Plant hormones auxin and cytokinin are the main regulators of the lateral root organogenesis. Additionally to their solo activities, the interaction between auxin and\r\ncytokinin plays crucial role in fine-tuning of lateral root development and growth. In particular, cytokinin modulates auxin distribution within the developing lateral root by affecting the endomembrane trafficking of auxin transporter PIN1 and promoting its vacuolar degradation (Marhavý et al., 2011, 2014). This effect is independent of transcription and\r\ntranslation. Therefore, it suggests novel, non-canonical cytokinin activity occuring possibly on the posttranslational level. Impact of cytokinin and other plant hormones on auxin transporters (including PIN1) on the posttranslational level is described in detail in the introduction part of this thesis in a form of a review (Semeradova et al., 2020). To gain insights into the molecular machinery underlying cytokinin effect on the endomembrane trafficking in the plant cell, in particular on the PIN1 degradation, we conducted two large proteomic screens: 1) Identification of cytokinin binding proteins using\r\nchemical proteomics. 2) Monitoring of proteomic and phosphoproteomic changes upon cytokinin treatment. In the first screen, we identified DYNAMIN RELATED PROTEIN 2A (DRP2A). We found that DRP2A plays a role in cytokinin regulated processes during the plant growth and that cytokinin treatment promotes destabilization of DRP2A protein. However, the role of DRP2A in the PIN1 degradation remains to be elucidated. In the second screen, we found VACUOLAR PROTEIN SORTING 9A (VPS9A). VPS9a plays crucial role in plant’s response to cytokin and in cytokinin mediated PIN1 degradation. Altogether, we identified proteins, which bind to cytokinin and proteins that in response to\r\ncytokinin exhibit significantly changed abundance or phosphorylation pattern. By combining information from these two screens, we can pave our way towards understanding of noncanonical cytokinin effects.","lang":"eng"}],"oa_version":"Published Version","alternative_title":["ISTA Thesis"],"month":"10"},{"day":"29","has_accepted_license":"1","year":"2021","date_published":"2021-07-29T00:00:00Z","doi":"10.15479/at:ista:9728","date_created":"2021-07-27T13:40:30Z","page":"118","publisher":"Institute of Science and Technology Austria","oa":1,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"mla":"Agrawal, Nishchal.

Multiphase flows are more difficult to investigate as their dynamics occur in large parameter space and involve complex phenomena such as preferential concentration, turbulence modulation, non-Newtonian rheology, etc. Over the last few decades, experiments in particle-laden flows have taken a back seat in favour of ever-improving computational resources. However, computers are still not powerful enough to simulate a real-world fluid with millions of finite-size particles. Experiments are essential not only because they offer a reliable way to investigate real-world multiphase flows but also because they serve to validate numerical studies and steer the research in a relevant direction. In this work, we have experimentally investigated particle-laden flows in pipes, and in particular, examined the effect of particles on the laminar-turbulent transition and the drag scaling in turbulent flows.\r\n\r\nFor particle-laden pipe flows, an earlier study [Matas et al., 2003] reported how the sub-critical (i.e., hysteretic) transition that occurs via localised turbulent structures called puffs is affected by the addition of particles. In this study, in addition to this known transition, we found a super-critical transition to a globally fluctuating state with increasing particle concentration. At the same time, the Newtonian-type transition via puffs is delayed to larger Reynolds numbers. At an even higher concentration, only the globally fluctuating state is found. The dynamics of particle-laden flows are hence determined by two competing instabilities that give rise to three flow regimes: Newtonian-type turbulence at low, a particle-induced globally fluctuating state at high, and a coexistence state at intermediate concentrations.\r\n\r\nThe effect of particles on turbulent drag is ambiguous, with studies reporting drag reduction, no net change, and even drag increase. The ambiguity arises because, in addition to particle concentration, particle shape, size, and density also affect the net drag. Even similar particles might affect the flow dissimilarly in different Reynolds number and concentration ranges. In the present study, we explored a wide range of both Reynolds number and concentration, using spherical as well as cylindrical particles. We found that the spherical particles do not reduce drag while the cylindrical particles are drag-reducing within a specific Reynolds number interval. The interval strongly depends on the particle concentration and the relative size of the pipe and particles. Within this interval, the magnitude of drag reduction reaches a maximum. These drag reduction maxima appear to fall onto a distinct power-law curve irrespective of the pipe diameter and particle concentration, and this curve can be considered as the maximum drag reduction asymptote for a given fibre shape. Such an asymptote is well known for polymeric flows but had not been identified for particle-laden flows prior to this work."}],"acknowledged_ssus":[{"_id":"M-Shop"}],"month":"07","alternative_title":["ISTA Thesis"],"ddc":["532"],"supervisor":[{"first_name":"Björn","id":"3A374330-F248-11E8-B48F-1D18A9856A87","full_name":"Hof, Björn","orcid":"0000-0003-2057-2754","last_name":"Hof"}],"date_updated":"2024-02-28T13:14:39Z","file_date_updated":"2022-07-29T22:30:05Z","department":[{"_id":"GradSch"},{"_id":"BjHo"}],"_id":"9728","status":"public","keyword":["Drag Reduction","Transition to Turbulence","Multiphase Flows","particle Laden Flows","Complex Flows","Experiments","Fluid Dynamics"],"type":"dissertation","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"}},{"publisher":"National Academy of Sciences","quality_controlled":"1","oa":1,"acknowledgement":"We thank T.

Here, we develop a coarse-grained model to systematically explore the effect that the structural properties of the lipid membrane and the nature of protein–membrane interactions have on the nucleation rates of amyloid fibrils. We identify two physically distinct nucleation pathways—protein-rich and lipid-rich—and quantify how the membrane fluidity and protein–membrane affinity control the relative importance of those molecular pathways. We find that the membrane’s susceptibility to reshaping and being incorporated into the fibrillar aggregates is a key determinant of its ability to promote protein aggregation. We then characterize the rates and the free-energy profile associated with this heterogeneous nucleation process, in which the surface itself participates in the aggregate structure. Finally, we compare quantitatively our data to experiments on membrane-catalyzed amyloid aggregation of α-synuclein, a protein implicated in Parkinson’s disease that predominately nucleates on membranes.

To accomplish this, we combine an evolutionary algorithm with coarse-grained molecular dynamics simulations and explore the solution space of ligand patterns on a nanoparticle that promote efficient and reliable cell uptake. Surprisingly, we find that in the regime of low ligand number the best-performing structures are characterized by ligands arranged into long one-dimensional chains that pattern the surface of the particle. We show that these chains of ligands provide particles with high rotational freedom and they lower the free energy barrier for membrane crossing. Our approach reveals a set of nonintuitive design rules that can be used to inform artificial nanoparticle construction and the search for inhibitors of viral entry.","lang":"eng"}],"pmid":1,"oa_version":"Published Version","main_file_link":[{"open_access":"1","url":"https://www.biorxiv.org/content/10.1101/2020.02.27.968149v1"}],"scopus_import":"1","intvolume":" 125","month":"11","date_updated":"2021-11-30T08:33:14Z","ddc":["530"],"extern":"1","file_date_updated":"2021-11-26T07:16:49Z","_id":"10344","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","status":"public","year":"2020","has_accepted_license":"1","publication":"Physical Review Letters","day":"23","date_created":"2021-11-26T07:10:43Z","date_published":"2020-11-23T00:00:00Z","doi":"10.1103/physrevlett.125.228101","acknowledgement":"We acknowledge support from EPSRC (J.

The resulting trajectories are usually consistent with some type of anomalous diffusion, but the molecular origins behind the observed anomalous behaviour are usually not obvious. Here we use coarse-grained molecular dynamics simulations to help identify the physical mechanisms that can give rise to experimentally observed trajectories of nanoscopic objects moving on biological membranes. We find that diffusion on membranes of high fluidities typically results in normal diffusion of the adsorbed nanoparticle, irrespective of the concentration of receptors, receptor clustering, or multivalent interactions between the particle and membrane receptors. Gel-like membranes on the other hand result in anomalous diffusion of the particle, which becomes more pronounced at higher receptor concentrations. This anomalous diffusion is characterised by local particle trapping in the regions of high receptor concentrations and fast hopping between such regions. The normal diffusion is recovered in the limit where the gel membrane is saturated with receptors. We conclude that hindered receptor diffusivity can be a common reason behind the observed anomalous diffusion of viruses, vesicles, and nanoparticles adsorbed on cell and model membranes. Our results enable direct comparison with experiments and offer a new route for interpreting motility experiments on cell membranes.","lang":"eng"}],"extern":"1","date_updated":"2021-11-26T07:00:33Z","keyword":["condensed matter physics","general chemistry"],"status":"public","type":"journal_article","article_type":"original","_id":"10341"},{"_id":"10346","keyword":["biophysics"],"status":"public","article_type":"original","type":"journal_article","extern":"1","date_updated":"2021-11-26T07:45:24Z","oa_version":"Published Version","pmid":1,"abstract":[{"text":"One of the most robust examples of self-assembly in living organisms is the formation of collagen architectures. Collagen type I molecules are a crucial component of the extracellular matrix, where they self-assemble into fibrils of well-defined axial striped patterns. This striped fibrillar pattern is preserved across the animal kingdom and is important for the determination of cell phenotype, cell adhesion, and tissue regulation and signaling. The understanding of the physical processes that determine such a robust morphology of self-assembled collagen fibrils is currently almost completely missing. Here, we develop a minimal coarse-grained computational model to identify the physical principles of the assembly of collagen-mimetic molecules. We find that screened electrostatic interactions can drive the formation of collagen-like filaments of well-defined striped morphologies. The fibril axial pattern is determined solely by the distribution of charges on the molecule and is robust to the changes in protein concentration, monomer rigidity, and environmental conditions. We show that the striped fibrillar pattern cannot be easily predicted from the interactions between two monomers but is an emergent result of multibody interactions. Our results can help address collagen remodeling in diseases and aging and guide the design of collagen scaffolds for biotechnological applications.","lang":"eng"}],"intvolume":" 119","month":"09","main_file_link":[{"open_access":"1","url":"https://www.biorxiv.org/content/10.1101/2020.06.08.140061v1"}],"scopus_import":"1","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0006-3495"]},"issue":"9","volume":119,"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","citation":{"ama":"Hafner AE, Gyori NG, Bench CA, Davis LK, Šarić A.

Low molecular weight oligomers are thought to be a central factor in the pathology of these diseases, as well as critical intermediates in the fibril formation process, and as such have received much recent attention. Moreover, on-pathway oligomeric intermediates are potential targets for therapeutic strategies aimed at interrupting the fibril formation process. However, a consistent framework for distinguishing on-pathway from off-pathway oligomers has hitherto been lacking and, in particular, no consensus definition of on- and off-pathway oligomers is available. In this paper, we argue that a non-binary definition of oligomers' contribution to fibril-forming pathways may be more informative and we suggest a quantitative framework, in which each oligomeric species is assigned a value between 0 and 1 describing its relative contribution to the formation of fibrils. First, we clarify the distinction between oligomers and fibrils, and then we use the formalism of reaction networks to develop a general definition for on-pathway oligomers, that yields meaningful classifications in the context of amyloid formation. By applying these concepts to Monte Carlo simulations of a minimal aggregating system, and by revisiting several previous studies of amyloid oligomers in light of our new framework, we demonstrate how to perform these classifications in practice. For each oligomeric species we obtain the degree to which it is on-pathway, highlighting the most effective pharmaceutical targets for the inhibition of amyloid fibril formation.","lang":"eng"}],"oa_version":"Published Version","pmid":1,"license":"https://creativecommons.org/licenses/by-nc/3.0/","volume":11,"issue":"24","publication_status":"published","publication_identifier":{"issn":["2041-6520"],"eissn":["2041-6539"]},"language":[{"iso":"eng"}],"tmp":{"short":"CC BY-NC (3.0)","name":"Creative Commons Attribution-NonCommercial 3.0 Unported (CC BY-NC 3.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/3.0/legalcode","image":"/images/cc_by_nc.png"},"type":"journal_article","article_type":"original","keyword":["general chemistry"],"status":"public","_id":"10350","date_updated":"2021-11-26T11:21:20Z","extern":"1"},{"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","citation":{"chicago":"Tarrason Risa, Gabriel, Fredrik Hurtig, Sian Bray, Anne E.

Here, in exploring the mechanism of cell division in S. acidocaldarius, we identify a role for the archaeal proteasome in regulating the transition from the end of one cell cycle to the beginning of the next. Further, we identify the archaeal ESCRT-III homolog, CdvB, as a key target of the proteasome and show that its degradation triggers division by allowing constriction of the CdvB1:CdvB2 ESCRT-III division ring. These findings offer a minimal mechanism for ESCRT-III–mediated membrane remodeling and point to a conserved role for the proteasome in eukaryotic and archaeal cell cycle control.","lang":"eng"}],"month":"08","intvolume":" 369","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://www.biorxiv.org/content/10.1101/774273v1"}]},{"extern":"1","date_updated":"2021-11-26T08:59:06Z","_id":"10347","status":"public","keyword":["multidisciplinary"],"type":"journal_article","article_type":"original","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0027-8424"],"eissn":["1091-6490"]},"publication_status":"published","volume":117,"issue":"39","pmid":1,"oa_version":"Published Version","abstract":[{"lang":"eng","text":"Understanding the mechanism of action of compounds capable of inhibiting amyloid-fibril formation is critical to the development of potential therapeutics against protein-misfolding diseases. A fundamental challenge for progress is the range of possible target species and the disparate timescales involved, since the aggregating proteins are simultaneously the reactants, products, intermediates, and catalysts of the reaction. It is a complex problem, therefore, to choose the states of the aggregating proteins that should be bound by the compounds to achieve the most potent inhibition. We present here a comprehensive kinetic theory of amyloid-aggregation inhibition that reveals the fundamental thermodynamic and kinetic signatures characterizing effective inhibitors by identifying quantitative relationships between the aggregation and binding rate constants.

By developing a general approach that combines theory, experiment and simulation, we reveal, in molecular detail, the mechanisms of Aβ42 oligomer dynamics during amyloid fibril formation. Even though all mature amyloid fibrils must originate as oligomers, we found that most Aβ42 oligomers dissociate into their monomeric precursors without forming new fibrils. Only a minority of oligomers converts into fibrillar structures. Moreover, the heterogeneous ensemble of oligomeric species interconverts on timescales comparable to those of aggregation.

How it breaks membranes, though, remains unknown. Here, we characterize a sequential polymerization of ESCRT-III subunits that, driven by a recruitment cascade and by continuous subunit-turnover powered by the ATPase Vps4, induces membrane deformation and fission. During this process, the exchange of Vps24 for Did2 induces a tilt in the polymer-membrane interface, which triggers transition from flat spiral polymers to helical filament to drive the formation of membrane protrusions, and ends with the formation of a highly constricted Did2-Ist1 co-polymer that we show is competent to promote fission when bound on the inside of membrane necks.

The collective FG Nup behavior has long been conceptualized either as a polymer brush, dominated by entropic and excluded-volume (repulsive) interactions, or as a hydrogel, dominated by cohesive (attractive) interactions between FG Nups. Here we compare mesoscale computational simulations with a wide range of experimental data to demonstrate that FG Nups are at the crossover point between these two regimes. Specifically, we find that repulsive and attractive interactions are balanced, resulting in morphologies and dynamics that are close to those of ideal polymer chains. We demonstrate that this property of FG Nups yields sufficient cohesion to seal the transport barrier, and yet maintains fast dynamics at the molecular scale, permitting the rapid polymer rearrangements needed for transport events."}],"month":"02","intvolume":" 101","scopus_import":"1","main_file_link":[{"url":"https://www.biorxiv.org/content/10.1101/571687","open_access":"1"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2470-0045"],"eissn":["2470-0053"]},"publication_status":"published","issue":"2","volume":101},{"extern":"1","date_updated":"2021-11-26T11:21:12Z","_id":"10353","keyword":["general physics and astronomy"],"status":"public","type":"journal_article","article_type":"original","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"volume":124,"issue":"4","oa_version":"Preprint","pmid":1,"abstract":[{"text":"Experiments have suggested that bacterial mechanosensitive channels separate into 2D clusters, the role of which is unclear.

As a result, controlling spin magnetism with electric fields—a longstanding technological goal in spintronics and multiferroics1,2—can be achieved only indirectly. Here we experimentally demonstrate direct electric-field control of magnetic states in an orbital Chern insulator3,4,5,6, a magnetic system in which non-trivial band topology favours long-range order of orbital angular momentum but the spins are thought to remain disordered7,8,9,10,11,12,13,14. We use van der Waals heterostructures consisting of a graphene monolayer rotationally faulted with respect to a Bernal-stacked bilayer to realize narrow and topologically non-trivial valley-projected moiré minibands15,16,17. At fillings of one and three electrons per moiré unit cell within these bands, we observe quantized anomalous Hall effects18 with transverse resistance approximately equal to h/2e2 (where h is Planck’s constant and e is the charge on the electron), which is indicative of spontaneous polarization of the system into a single-valley-projected band with a Chern number equal to two. At a filling of three electrons per moiré unit cell, we find that the sign of the quantum anomalous Hall effect can be reversed via field-effect control of the chemical potential; moreover, this transition is hysteretic, which we use to demonstrate non-volatile electric-field-induced reversal of the magnetic state. A theoretical analysis19 indicates that the effect arises from the topological edge states, which drive a change in sign of the magnetization and thus a reversal in the favoured magnetic state. Voltage control of magnetic states can be used to electrically pattern non-volatile magnetic-domain structures hosting chiral edge states, with applications ranging from reconfigurable microwave circuit elements to ultralow-power magnetic memories.","lang":"eng"}],"pmid":1,"oa_version":"Preprint"},{"date_published":"2020-10-01T00:00:00Z","date_created":"2022-01-20T10:55:36Z","page":"55","day":"01","language":[{"iso":"eng"}],"publication":"arXiv","year":"2020","publication_status":"submitted","month":"10","oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2010.00584"}],"oa_version":"Preprint","acknowledgement":"We thank NSF CMP program for suggestions regarding the topic and general structure of the workshop.

In this manuscript we share our personal views of what the major open problems are in correlated electron systems and we discuss some possible routes to make progress in this rich and fascinating field. This manuscript is the result of the vigorous discussions and deliberations that took place at Johns Hopkins University during a three-day workshop January 27, 28, and 29, 2020 that brought together six senior scientists and 46 more junior scientists.

Inspired by the structure of the nervous system of the soil-worm, C. elegans, we introduce ordinary neural circuits (ONCs), defined as the model of biological neural circuits reparameterized for the control of alternative tasks. We first demonstrate that ONCs realize networks with higher maximum flow compared to arbitrary wired networks. We then learn instances of ONCs to control a series of robotic tasks, including the autonomous parking of a real-world rover robot. For reconfiguration of the purpose of the neural circuit, we adopt a search-based optimization algorithm. Ordinary neural circuits perform on par and, in some cases, significantly surpass the performance of contemporary deep learning models. ONC networks are compact, 77% sparser than their counterpart neural controllers, and their neural dynamics are fully interpretable at the cell-level."}],"department":[{"_id":"GradSch"},{"_id":"ToHe"}],"file_date_updated":"2022-01-26T11:08:51Z","ddc":["000"],"date_updated":"2022-01-26T11:14:27Z","status":"public","type":"conference","conference":{"name":"ML: Machine Learning","end_date":"2020-07-18","location":"Virtual","start_date":"2020-07-12"},"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/3.0/legalcode","short":"CC BY-NC-ND (3.0)"},"series_title":"PMLR","_id":"10673"},{"date_updated":"2022-01-27T10:58:38Z","extern":"1","_id":"10693","type":"conference","conference":{"end_date":"2020-03-06","location":"Denver, CO, United States","start_date":"2020-03-02","name":"APS: American Physical Society"},"status":"public","publication_identifier":{"issn":["0003-0503"]},"publication_status":"published","language":[{"iso":"eng"}],"volume":65,"issue":"1","abstract":[{"text":"High quality graphene heterostructures host an array of fractional quantum Hall isospin ferromagnets with diverse spin and valley orders. While a variety of phase transitions have been observed, disentangling the isospin phase diagram of these states is hampered by the absence of direct probes of spin and valley order. I will describe nonlocal transport measurements based on launching spin waves from a gate defined lateral heterojunction, performed in ultra-clean Corbino geometry graphene devices. At high magnetic fields, we find that the spin-wave transport signal is detected in all FQH states between ν = 0 and 1; however, between ν = 1 and 2 only odd numerator FQH states show finite nonlocal transport, despite the identical ground state spin polarizations in odd- and even numerator states. The results reveal that the neutral spin-waves are both spin and sublattice polarized making them a sensitive probe of ground state sublattice structure. Armed with this understanding, we use nonlocal transport signal to a magnetic field tuned isospin phase transition, showing that the emergent even denominator state at ν = 1/2 in monolayer graphene is indeed a multicomponent state featuring equal populations on each sublattice.","lang":"eng"}],"oa_version":"Published Version","alternative_title":["Bulletin of the American Physical Society"],"main_file_link":[{"url":"https://meetings.aps.org/Meeting/MAR20/Session/B54.7","open_access":"1"}],"month":"03","intvolume":" 65","citation":{"mla":"Zhou, Haoxin, et al. “Sublattice Resolved Spin Wave Transport through Graphene Fractional Quantum Hall States as a Probe of Isospin Order.” APS March Meeting 2020, vol. 65, no. 1, B54. 00007, American Physical Society, 2020.","apa":"Zhou, H., Polshyn, H., Tanaguchi, T., Watanabe, K., & Young, A.

In this system, the quantization arises from spontaneous ferromagnetic polarization into a single spin and valley moiré subband, which is topological despite the lack of spin orbit coupling.

For example, electron solids may prevail close to integer filling of the Landau levels before giving way to fractional quantum Hall liquids at higher carrier density1,2. Here, we report the observation of an electron solid with non-collinear spin texture in monolayer graphene, consistent with solidification of skyrmions3—topological spin textures characterized by quantized electrical charge4,5. We probe the spin texture of the solids using a modified Corbino geometry that allows ferromagnetic magnons to be launched and detected6,7. We find that magnon transport is highly efficient when one Landau level is filled (ν=1), consistent with quantum Hall ferromagnetic spin polarization. However, even minimal doping immediately quenches the magnon signal while leaving the vanishing low-temperature charge conductivity unchanged. Our results can be understood by the formation of a solid of charged skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay. Data near fractional fillings show evidence of several fractional skyrmion solids, suggesting that graphene hosts a highly tunable landscape of coupled spin and charge orders."}]},{"publisher":"Wiley","quality_controlled":"1","oa":1,"doi":"10.1002/adbi.202000044","date_published":"2020-05-01T00:00:00Z","date_created":"2022-04-07T07:43:57Z","has_accepted_license":"1","year":"2020","day":"01","publication":"Advanced Biosystems","article_number":"2000044","author":[{"last_name":"Bersini","full_name":"Bersini, Simone","first_name":"Simone"},{"first_name":"Rafael","last_name":"Arrojo e Drigo","full_name":"Arrojo e Drigo, Rafael"},{"last_name":"Huang","full_name":"Huang, Ling","first_name":"Ling"},{"first_name":"Maxim N.","full_name":"Shokhirev, Maxim N.","last_name":"Shokhirev"},{"first_name":"Martin W","id":"86c0d31b-b4eb-11ec-ac5a-eae7b2e135ed","full_name":"HETZER, Martin W","orcid":"0000-0002-2111-992X","last_name":"HETZER"}],"article_processing_charge":"No","external_id":{"pmid":["32402127"]},"title":"Transcriptional and functional changes of the human microvasculature during physiological aging and Alzheimer disease","citation":{"chicago":"Bersini, Simone, Rafael Arrojo e Drigo, Ling Huang, Maxim N.

However, it is largely unknown which factors drive the age-dependent or pathological decline of the vasculature and how vascular defects relate to tissue aging. The goal of the study is to design a multianalytical approach to identify how the cellular microenvironment (i.e., fibroblasts) and serum from healthy donors of different ages or Alzheimer disease (AD) patients can modulate the functionality of organ-specific vascular endothelial cells (VECs). Long-living human microvascular networks embedding VECs and fibroblasts from skin biopsies are generated. RNA-seq, secretome analyses, and microfluidic assays demonstrate that fibroblasts from young donors restore the functionality of aged endothelial cells, an effect also achieved by serum from young donors. New biomarkers of vascular aging are validated in human biopsies and it is shown that young serum induces angiopoietin-like-4, which can restore compromised vascular barriers. This strategy is then employed to characterize transcriptional/functional changes induced on the blood–brain barrier by AD serum, demonstrating the importance of PTP4A3 in the regulation of permeability. Features of vascular degeneration during aging and AD are recapitulated, and a tool to identify novel biomarkers that can be exploited to develop future therapeutics modulating vascular function is established.","lang":"eng"}],"oa_version":"Published Version","pmid":1,"volume":4,"issue":"5","publication_identifier":{"issn":["2366-7478","2366-7478"]},"publication_status":"published","file":[{"content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"5584d9a1609812dc75c02ce1e35d2ec0","file_id":"11134","success":1,"date_updated":"2022-04-08T07:06:05Z","file_size":2490829,"creator":"dernst","date_created":"2022-04-08T07:06:05Z","file_name":"2020_AdvancedBiosystems_Bersini.pdf"}],"language":[{"iso":"eng"}],"type":"journal_article","article_type":"original","tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png"},"status":"public","keyword":["General Biochemistry","Genetics and Molecular Biology","Biomedical Engineering","Biomaterials"],"_id":"11056","file_date_updated":"2022-04-08T07:06:05Z","date_updated":"2022-07-18T08:30:48Z","extern":"1","ddc":["570"]},{"title":"Direct reprogramming of human smooth muscle and vascular endothelial cells reveals defects associated with aging and Hutchinson-Gilford progeria syndrome","external_id":{"pmid":["32896271"]},"article_processing_charge":"No","author":[{"first_name":"Simone","last_name":"Bersini","full_name":"Bersini, Simone"},{"first_name":"Roberta","full_name":"Schulte, Roberta","last_name":"Schulte"},{"last_name":"Huang","full_name":"Huang, Ling","first_name":"Ling"},{"full_name":"Tsai, Hannah","last_name":"Tsai","first_name":"Hannah"},{"last_name":"HETZER","orcid":"0000-0002-2111-992X","full_name":"HETZER, Martin W","id":"86c0d31b-b4eb-11ec-ac5a-eae7b2e135ed","first_name":"Martin W"}],"user_id":"72615eeb-f1f3-11ec-aa25-d4573ddc34fd","citation":{"ista":"Bersini S, Schulte R, Huang L, Tsai H, Hetzer M. 2020.

Here, we generated induced vascular endothelial cells (iVECs) and smooth muscle cells (iSMCs) by direct reprogramming of healthy human fibroblasts from donors of different ages and Hutchinson-Gilford Progeria Syndrome (HGPS) patients. iVECs induced from old donors revealed upregulation of GSTM1 and PALD1, genes linked to oxidative stress, inflammation and endothelial junction stability, as vascular aging markers. A functional assay performed on PALD1 KD VECs demonstrated a recovery in vascular permeability. We found that iSMCs from HGPS donors overexpressed bone morphogenetic protein (BMP)−4, which plays a key role in both vascular calcification and endothelial barrier damage observed in HGPS. Strikingly, BMP4 concentrations are higher in serum from HGPS vs. age-matched mice. Furthermore, targeting BMP4 with blocking antibody recovered the functionality of the vascular barrier in vitro, hence representing a potential future therapeutic strategy to limit cardiovascular dysfunction in HGPS. These results show that iVECs and iSMCs retain disease-related signatures, allowing modeling of vascular aging and HGPS in vitro.","lang":"eng"}]},{"keyword":["General Neuroscience"],"status":"public","article_type":"review","type":"journal_article","_id":"11054","extern":"1","date_updated":"2022-07-18T08:29:35Z","intvolume":" 106","month":"06","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.neuron.2020.05.031"}],"scopus_import":"1","pmid":1,"oa_version":"Published Version","abstract":[{"text":"In recent years, the nuclear pore complex (NPC) has emerged as a key player in genome regulation and cellular homeostasis.

Many aspects of the underlying principles that mediate transcriptional memory and reactivation in the daughter cells remain unclear. Here, we used ChIP-seq on synchronized cells at different stages after mitosis to generate genome-wide maps of histone modifications. Combined with EU-RNA-seq and Hi-C analyses, we found that during prometaphase, promoters, enhancers, and insulators retain H3K4me3 and H3K4me1, while losing H3K27ac. Enhancers globally retaining mitotic H3K4me1 or locally retaining mitotic H3K27ac are associated with cell type-specific genes and their transcription factors for rapid transcriptional activation. As cells exit mitosis, promoters regain H3K27ac, which correlates with transcriptional reactivation. Insulators also gain H3K27ac and CCCTC-binding factor (CTCF) in anaphase/telophase. This increase of H3K27ac in anaphase/telophase is required for posttranscriptional activation and may play a role in the establishment of topologically associating domains (TADs). Together, our results suggest that the genome is reorganized in a sequential order, in which histone methylations occur first in prometaphase, histone acetylation, and CTCF in anaphase/telophase, transcription in cytokinesis, and long-range chromatin interactions in early G1. We thus provide insights into the histone modification landscape that allows faithful reestablishment of the transcriptional program and TADs during cell division.","lang":"eng"}],"pmid":1,"oa_version":"Published Version","scopus_import":"1","month":"04","intvolume":" 34","publication_identifier":{"issn":["0890-9369","1549-5477"]},"publication_status":"published","file":[{"file_name":"2020_GenesDevelopment_Kang.pdf","date_created":"2022-04-08T07:12:33Z","file_size":4406772,"date_updated":"2022-04-08T07:12:33Z","creator":"dernst","success":1,"checksum":"84e92d40e67936c739628315c238daf9","file_id":"11136","content_type":"application/pdf","relation":"main_file","access_level":"open_access"}],"language":[{"iso":"eng"}],"volume":34,"issue":"13-14"},{"article_number":"e201900623","citation":{"short":"S.

Nup93 depletion induced stress fiber formation associated with reduced cell migration/proliferation and impaired expression of mesenchymal-like genes.

The Lyα emitter (LAE) fraction, XLAE, is a potentially powerful probe of the evolution of the intergalactic neutral hydrogen gas fraction. However, uncertainties in the measurement of XLAE are still under debate.\r\nAims. Thanks to deep data obtained with the integral field spectrograph Multi Unit Spectroscopic Explorer (MUSE), we can measure the evolution of the LAE fraction homogeneously over a wide redshift range of z ≈ 3–6 for UV-faint galaxies (down to UV magnitudes of M1500 ≈ −17.75). This is a significantly fainter range than in former studies (M1500 ≤ −18.75) and it allows us to probe the bulk of the population of high-redshift star-forming galaxies.\r\nMethods. We constructed a UV-complete photometric-redshift sample following UV luminosity functions and measured the Lyα emission with MUSE using the latest (second) data release from the MUSE Hubble Ultra Deep Field Survey.\r\nResults. We derived the redshift evolution of XLAE for M1500 ∈ [ − 21.75; −17.75] for the first time with a equivalent width range EW(Lyα) ≥ 65 Å and found low values of XLAE ≲ 30% at z ≲ 6. The best-fit linear relation is XLAE = 0.07+0.06−0.03z − 0.22+0.12−0.24. For M1500 ∈ [ − 20.25; −18.75] and EW(Lyα) ≥ 25 Å, our XLAE values are consistent with those in the literature within 1σ at z ≲ 5, but our median values are systematically lower than reported values over the whole redshift range. In addition, we do not find a significant dependence of XLAE on M1500 for EW(Lyα) ≥ 50 Å at z ≈ 3–4, in contrast with previous work. The differences in XLAE mainly arise from selection biases for Lyman Break Galaxies (LBGs) in the literature: UV-faint LBGs are more easily selected if they have strong Lyα emission, hence XLAE is biased towards higher values when those samples are used.\r\nConclusions. Our results suggest either a lower increase of XLAE towards z ≈ 6 than previously suggested, or even a turnover of XLAE at z ≈ 5.5, which may be the signature of a late or patchy reionization process. We compared our results with predictions from a cosmological galaxy evolution model. We find that a model with a bursty star formation (SF) can reproduce our observed LAE fractions much better than models where SF is a smooth function of time."}]},{"article_type":"original","type":"journal_article","keyword":["Space and Planetary Science","Astronomy and Astrophysics galaxies: high-redshift / galaxies: formation / galaxies: evolution / cosmology: observations"],"status":"public","_id":"11504","date_updated":"2022-07-19T09:36:58Z","extern":"1","main_file_link":[{"url":"https://arxiv.org/abs/2002.05731","open_access":"1"}],"scopus_import":"1","intvolume":" 635","month":"03","abstract":[{"lang":"eng","text":"We present spatially resolved maps of six individually-detected Lyman α haloes (LAHs) as well as a first statistical analysis of the Lyman α (Lyα) spectral signature in the circum-galactic medium of high-redshift star-forming galaxies (−17.5 > MUV > −21.5) using the Multi-Unit Spectroscopic Explorer. Our resolved spectroscopic analysis of the LAHs reveals significant intrahalo variations of the Lyα line profile. Using a three-dimensional two-component model for the Lyα emission, we measured the full width at half maximum (FWHM), the peak velocity shift, and the asymmetry of the Lyα line in the core and in the halo of 19 galaxies. We find that the Lyα line shape is statistically different in the halo compared to the core (in terms of width, peak wavelength, and asymmetry) for ≈40% of our galaxies. Similarly to object-by-object based studies and a recent resolved study using lensing, we find a correlation between the peak velocity shift and the width of the Lyα line both at the interstellar and circum-galactic scales. This trend has been predicted by radiative transfer simulations of galactic winds as a result of resonant scattering in outflows. While there is a lack of correlation between the spectral properties and the spatial scale lengths of our LAHs, we find a correlation between the width of the line in the LAH and the halo flux fraction. Interestingly, UV bright galaxies (MUV < −20) show broader, more redshifted, and less asymmetric Lyα lines in their haloes. The most significant correlation found is for the FWHM of the line and the UV continuum slope of the galaxy, suggesting that the redder galaxies have broader Lyα lines. The generally broad and red line shapes found in the halo component suggest that the Lyα haloes are powered either by scattering processes through an outflowing medium, fluorescent emission from outflowing cold clumps of gas, or a mix of both. Considering the large diversity of the Lyα line profiles observed in our sample and the lack of strong correlation, the interpretation of our results is still broadly open and underlines the need for realistic spatially resolved models of the LAHs."}],"oa_version":"Published Version","volume":635,"publication_status":"published","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"language":[{"iso":"eng"}],"article_number":"A82","article_processing_charge":"No","external_id":{"arxiv":["2002.05731"]},"author":[{"full_name":"Leclercq, Floriane","last_name":"Leclercq","first_name":"Floriane"},{"first_name":"Roland","last_name":"Bacon","full_name":"Bacon, Roland"},{"first_name":"Anne","full_name":"Verhamme, Anne","last_name":"Verhamme"},{"first_name":"Thibault","last_name":"Garel","full_name":"Garel, Thibault"},{"first_name":"Jérémy","full_name":"Blaizot, Jérémy","last_name":"Blaizot"},{"last_name":"Brinchmann","full_name":"Brinchmann, Jarle","first_name":"Jarle"},{"last_name":"Cantalupo","full_name":"Cantalupo, Sebastiano","first_name":"Sebastiano"},{"full_name":"Claeyssens, Adélaïde","last_name":"Claeyssens","first_name":"Adélaïde"},{"last_name":"Conseil","full_name":"Conseil, Simon","first_name":"Simon"},{"full_name":"Contini, Thierry","last_name":"Contini","first_name":"Thierry"},{"full_name":"Hashimoto, Takuya","last_name":"Hashimoto","first_name":"Takuya"},{"first_name":"Edmund Christian","full_name":"Herenz, Edmund Christian","last_name":"Herenz"},{"first_name":"Haruka","last_name":"Kusakabe","full_name":"Kusakabe, Haruka"},{"first_name":"Raffaella Anna","last_name":"Marino","full_name":"Marino, Raffaella Anna"},{"first_name":"Michael","last_name":"Maseda","full_name":"Maseda, Michael"},{"id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J","last_name":"Matthee","orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J"},{"full_name":"Mitchell, Peter","last_name":"Mitchell","first_name":"Peter"},{"full_name":"Pezzulli, Gabriele","last_name":"Pezzulli","first_name":"Gabriele"},{"first_name":"Johan","last_name":"Richard","full_name":"Richard, Johan"},{"first_name":"Kasper Borello","full_name":"Schmidt, Kasper Borello","last_name":"Schmidt"},{"full_name":"Wisotzki, Lutz","last_name":"Wisotzki","first_name":"Lutz"}],"title":"The MUSE Hubble Ultra Deep field survey: XIII.

We used data from the MUSE Hubble Ultra Deep Survey to construct mean rest-frame spectra of continuum-faint (median MUV of −18 and down to MUV of −16), low stellar mass (median value of 108.4 M⊙ and down to 107 M⊙) LAEs at redshift z ≳ 3. We computed various averaged spectra of LAEs, subsampled on the basis of their observational (e.g., Lyα strength, UV magnitude and spectral slope) and physical (e.g., stellar mass and star-formation rate) properties. We searched for UV spectral features other than Lyα, such as higher ionization nebular emission lines and absorption features. We successfully observed the O III]λ1666 and [C III]λ1907+C III]λ1909 collisionally excited emission lines and the He IIλ1640 recombination feature, as well as the resonant C IVλλ1548,1551 doublet either in emission or P-Cygni. We compared the observed spectral properties of the different mean spectra and find the emission lines to vary with the observational and physical properties of the LAEs. In particular, the mean spectra of LAEs with larger Lyα equivalent widths, fainter UV magnitudes, bluer UV spectral slopes, and lower stellar masses show the strongest nebular emission. The line ratios of these lines are similar to those measured in the spectra of local metal-poor galaxies, while their equivalent widths are weaker compared to the handful of extreme values detected in individual spectra of z > 2 galaxies. This suggests that weak UV features are likely ubiquitous in high z, low-mass, and faint LAEs. We publicly released the stacked spectra, as they can serve as empirical templates for the design of future observations, such as those with the James Webb Space Telescope and the Extremely Large Telescope."}],"oa_version":"Published Version","date_updated":"2022-07-19T09:35:43Z","extern":"1","type":"journal_article","article_type":"original","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: evolution / galaxies: high-redshift / ISM: lines and bands / ultraviolet: ISM / ultraviolet: galaxies"],"status":"public","_id":"11501","date_created":"2022-07-06T09:38:16Z","date_published":"2020-09-18T00:00:00Z","doi":"10.1051/0004-6361/202038133","year":"2020","publication":"Astronomy & Astrophysics","day":"18","oa":1,"quality_controlled":"1","publisher":"EDP Sciences","acknowledgement":"We thank Margherita Talia, Stéphane Charlot, Adele Plat and Alba Vidal-García for helpful discussions.

With only two masks of Keck/MOSFIRE near-IR spectroscopy in both H (∼1.47–1.81 μm) and K (∼1.92–2.40 μm) bands (∼1.5 hr each), we confirm 35 unique protocluster members with at least two emission lines detected with S/N > 3. Combined with 12 extra members from the zCOSMOS-deep spectroscopic survey (47 in total), we estimate a mean redshift and a line-of-sight velocity dispersion of zmean = 2.23224 ± 0.00101 and σlos = 645 ± 69 km s−1 for this protocluster, respectively. Assuming virialization and spherical symmetry for the system, we estimate a total mass of Mvir ∼ (1–2) ×1014M⊙ for the structure. We evaluate a number density enhancement of δg ∼ 7 for this system and we argue that the structure is likely not fully virialized at z ∼ 2.2. However, in a spherical collapse model, δg is expected to grow to a linear matter enhancement of ∼1.9 by z = 0, exceeding the collapse threshold of 1.69, and leading to a fully collapsed and virialized Coma-type structure with a total mass of Mdyn(z = 0) ∼ 9.2 × 1014M⊙ by now. This observationally efficient confirmation suggests that large narrowband emission-line galaxy surveys, when combined with ancillary photometric data, can be used to effectively trace the large-scale structure and protoclusters at a time when they are mostly dominated by star-forming galaxies.","lang":"eng"}],"extern":"1","date_updated":"2022-07-19T09:31:35Z","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"status":"public","article_type":"original","type":"journal_article","_id":"11513","date_created":"2022-07-06T13:10:51Z","doi":"10.3847/1538-4357/ab75c3","date_published":"2020-03-19T00:00:00Z","publication":"The Astrophysical Journal","day":"19","year":"2020","oa":1,"publisher":"IOP Publishing","quality_controlled":"1","acknowledgement":"We are thankful to the anonymous referee for useful comments and suggestions that improved the quality of this paper.

Here, we measure the average velocity offset for a sample of 96 z ≈ 3.3 Ly α emitters (LAEs) with a median Ly α flux (luminosity) of ≈10−17 erg cm−2 s−1 (≈1042 erg s−1) and a median star formation rate (SFR) of ≈1.3 M⊙ yr−1 (not corrected for possible dust extinction), detected by the Multi-Unit Spectroscopic Explorer as part of our MUSEQuBES circumgalactic medium (CGM) survey. By postulating that the stacked CGM absorption profiles of these LAEs, probed by eight background quasars, must be centred on the systemic redshift, we measure an average velocity offset, Voffset = 171\\pm 8 km s−1, between the Ly α emission peak and the systemic redshift. The observed Voffset is lower by factors of ≈1.4 and ≈2.6 compared to the velocity offsets measured for narrow-band-selected LAEs and Lyman break galaxies, respectively, which probe galaxies with higher masses and SFRs. Consistent with earlier studies based on direct measurements for individual objects, we find that the Voffset is correlated with the full width at half-maximum of the red peak of the Ly α line, and anticorrelated with the rest-frame equivalent width. Moreover, we find that Voffset is correlated with SFR with a sub-linear scaling relation, Voffset∝SFR0.16±0.03. Adopting the mass scaling for main-sequence galaxies, such a relation suggests that Voffset scales with the circular velocity of the dark matter haloes hosting the LAEs."}],"intvolume":" 496","month":"08","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1910.03593"}],"scopus_import":"1","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"volume":496,"issue":"2","related_material":{"link":[{"relation":"erratum","url":"https://doi.org/10.1093/mnras/staa2668"}]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Muzahid S, Schaye J, Marino RA, Cantalupo S, Brinchmann J, Contini T, Wendt M, Wisotzki L, Zabl J, Bouché N, Akhlaghi M, Chen H-W, Claeyssens A, Johnson S, Leclercq F, Maseda M, Matthee JJ, Richard J, Urrutia T, Verhamme A. 2020.

Previous studies have suggested that it may host an extreme ionizing source. Here, we present deep integral field spectroscopy of CR7 with VLT/Multi Unit Spectroscopic Explorer (MUSE). We measure extended emission with a similar halo scale length as typical LAEs at z ≈ 5. CR7’s Ly α halo is clearly elongated along the direction connecting the multiple components, likely tracing the underlying gas distribution. The Ly α emission originates almost exclusively from the brightest UV component, but we also identify a faint kinematically distinct Ly α emitting region nearby a fainter component. Combined with new near-infrared data, the MUSE data show that the rest-frame Ly α equivalent width (EW) is ≈100 Å. This is a factor 4 higher than the EW measured in low-redshift analogues with carefully matched Ly α profiles (and thus arguably H I column density), but this EW can plausibly be explained by star formation. Alternative scenarios requiring active galactic nucleus (AGN) powering are also disfavoured by the narrower and steeper Ly α spectrum and much smaller IR to UV ratio compared to obscured AGN in other Ly α blobs. CR7’s Ly α emission, while extremely luminous, resembles the emission in more common LAEs at lower redshifts very well and is likely powered by a young metal-poor starburst.","lang":"eng"}],"extern":"1","date_updated":"2022-08-18T11:04:05Z","status":"public","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: evolution","galaxies: high-redshift","dark ages","reionization","first stars","cosmology: observations"],"type":"journal_article","article_type":"original","_id":"11529","date_published":"2020-10-01T00:00:00Z","doi":"10.1093/mnras/staa2550","date_created":"2022-07-07T10:36:01Z","page":"3043-3059","day":"01","publication":"Monthly Notices of the Royal Astronomical Society","year":"2020","publisher":"Oxford University Press","quality_controlled":"1","oa":1,"title":"The nature of CR7 revealed with MUSE: A young starburst powering extended Ly α emission at z = 6.6","author":[{"orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J","last_name":"Matthee","id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J"},{"full_name":"Pezzulli, Gabriele","last_name":"Pezzulli","first_name":"Gabriele"},{"full_name":"Mackenzie, Ruari","last_name":"Mackenzie","first_name":"Ruari"},{"full_name":"Cantalupo, Sebastiano","last_name":"Cantalupo","first_name":"Sebastiano"},{"first_name":"Haruka","full_name":"Kusakabe, Haruka","last_name":"Kusakabe"},{"last_name":"Leclercq","full_name":"Leclercq, Floriane","first_name":"Floriane"},{"full_name":"Sobral, David","last_name":"Sobral","first_name":"David"},{"last_name":"Richard","full_name":"Richard, Johan","first_name":"Johan"},{"first_name":"Lutz","full_name":"Wisotzki, Lutz","last_name":"Wisotzki"},{"first_name":"Simon","last_name":"Lilly","full_name":"Lilly, Simon"},{"first_name":"Leindert","full_name":"Boogaard, Leindert","last_name":"Boogaard"},{"first_name":"Raffaella","full_name":"Marino, Raffaella","last_name":"Marino"},{"last_name":"Maseda","full_name":"Maseda, Michael","first_name":"Michael"},{"first_name":"Themiya","last_name":"Nanayakkara","full_name":"Nanayakkara, Themiya"}],"external_id":{"arxiv":["2008.01731"]},"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"J.J.

Lyman α (Ly α) emitters (LAEs) at z ∼ 2–6. We find typical stellar masses of 109.3 ± 0.6 M⊙ and star formation rates (SFR) of SFRSED=4.4+10.5−2.4 M⊙ yr−1 and SFRLyα=5.9+6.3−2.6 M⊙ yr−1, combined with very blue UV slopes of β=−2.1+0.5−0.4, but with significant variations within the population. MUV and β are correlated in a similar way to UV-selected sources, but LAEs are consistently bluer. This suggests that LAEs are the youngest and/or most dust-poor subset of the UV-selected population. We also study the Ly α rest-frame equivalent width (EW0) and find 45 ‘extreme’ LAEs with EW0 > 240 Å (3σ), implying a low number density of (7 ± 1) × 10−7 Mpc−3. Overall, we measure little to no evolution of the Ly α EW0 and scale length parameter (w0), which are consistently high (EW0=140+280−70 Å, w0=129+11−11 Å) from z ∼ 6 to z ∼ 2 and below. However, w0 is anticorrelated with MUV and stellar mass. Our results imply that sources selected as LAEs have a high Ly α escape fraction (fesc,Ly α) irrespective of cosmic time, but fesc,Ly α is still higher for UV-fainter and lower mass LAEs. The least massive LAEs (<109.5 M⊙) are typically located above the star formation ‘main sequence’ (MS), but the offset from the MS decreases towards z ∼ 6 and towards 1010 M⊙. Our results imply a lack of evolution in the properties of LAEs across time and reveals the increasing overlap in properties of LAEs and UV-continuum selected galaxies as typical star-forming galaxies at high redshift effectively become LAEs.","lang":"eng"}],"title":"The evolution of rest-frame UV properties, Ly α EWs, and the SFR–stellar mass relation at z ∼ 2–6 for SC4K LAEs","external_id":{"arxiv":["1910.02959"]},"article_processing_charge":"No","author":[{"first_name":"S","full_name":"Santos, S","last_name":"Santos"},{"first_name":"D","full_name":"Sobral, D","last_name":"Sobral"},{"last_name":"Matthee","full_name":"Matthee, Jorryt J","orcid":"0000-0003-2871-127X","first_name":"Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720"},{"first_name":"J","last_name":"Calhau","full_name":"Calhau, J"},{"first_name":"E","full_name":"da Cunha, E","last_name":"da Cunha"},{"full_name":"Ribeiro, B","last_name":"Ribeiro","first_name":"B"},{"full_name":"Paulino-Afonso, A","last_name":"Paulino-Afonso","first_name":"A"},{"first_name":"P","last_name":"Arrabal Haro","full_name":"Arrabal Haro, P"},{"first_name":"J","last_name":"Butterworth","full_name":"Butterworth, J"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Santos S, Sobral D, Matthee JJ, Calhau J, da Cunha E, Ribeiro B, Paulino-Afonso A, Arrabal Haro P, Butterworth J. 2020.

Ly α emission is clearly detected with S/N ≈ 40 and FWHM of 374 km s−1.

The Ly α profile is broader and redshifted with respect to the [C II] line (by 213 km s−1), but there are spatial variations that are qualitatively similar in both lines and coincide with resolved UV components. This suggests that the emission originates from two components with plausibly different H I column densities. We place VR7 in the context of other galaxies at similar and lower redshift. The Ly α halo scale length is similar at different redshifts and velocity shifts with respect to the systemic are typically smaller. Overall, we find little indications of a more neutral vicinity at higher redshift.

We isolate a sample of 35 z ≈ 4–5 continuum-faint Lyman-α emitters from deep VLT/MUSE spectroscopy and directly measure their H α emission using stacked Spitzer/IRAC Ch. 1 photometry. Based on Hubble Space Telescope imaging, we determine that the average UV continuum magnitude is fainter than −16 (≈ 0.01 L⋆), implying a median Lyman-α equivalent width of 259 Å. By combining the H α measurement with the UV magnitude, we determine the ionizing photon production efficiency, ξion, a first for such faint galaxies. The measurement of log10 (ξion [Hz erg−1]) = 26.28 (+0.28−0.40) is in excess of literature measurements of both continuum- and emission line-selected samples, implying a more efficient production of ionizing photons in these lower luminosity, Lyman-α-selected systems. We conclude that this elevated efficiency can be explained by stellar populations with metallicities between 4 × 10−4 and 0.008, with light-weighted ages less than 3 Myr.","lang":"eng"}],"volume":493,"issue":"4","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]}},{"type":"journal_article","article_type":"original","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: active","galaxies: high-redshift","intergalactic medium","quasars: emission lines","quasars: general"],"status":"public","_id":"11530","date_updated":"2022-08-18T11:17:47Z","extern":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2005.01732"}],"scopus_import":"1","intvolume":" 495","month":"06","abstract":[{"text":"A prediction of the classic active galactic nucleus (AGN) unification model is the presence of ionization cones with different orientations depending on the AGN type. Confirmations of this model exist for present times, but it is less clear in the early Universe. Here, we use the morphology of giant Ly α nebulae around AGNs at redshift z ∼ 3 to probe AGN emission and therefore the validity of the AGN unification model at this redshift. We compare the spatial morphology of 19 nebulae previously found around type I AGNs with a new sample of four Ly α nebulae detected around type II AGNs. Using two independent techniques, we find that nebulae around type II AGNs are more asymmetric than around type I, at least at radial distances r > 30 physical kpc (pkpc) from the ionizing source. We conclude that the type I and type II AGNs in our sample show evidence of different surrounding ionizing geometries. This suggests that the classical AGN unification model is also valid for high-redshift sources. Finally, we discuss how the lack of asymmetry in the inner parts (r ≲ 30 pkpc) and the associated high values of the He II to Ly α ratios in these regions could indicate additional sources of (hard) ionizing radiation originating within or in proximity of the AGN host galaxies. This work demonstrates that the morphologies of giant Ly α nebulae can be used to understand and study the geometry of high-redshift AGNs on circumnuclear scales and it lays the foundation for future studies using much larger statistical samples.","lang":"eng"}],"oa_version":"Preprint","issue":"2","volume":495,"publication_status":"published","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]},"language":[{"iso":"eng"}],"article_processing_charge":"No","external_id":{"arxiv":["2005.01732"]},"author":[{"first_name":"J S","full_name":"den Brok, J S","last_name":"den Brok"},{"first_name":"S","last_name":"Cantalupo","full_name":"Cantalupo, S"},{"first_name":"R","last_name":"Mackenzie","full_name":"Mackenzie, R"},{"last_name":"Marino","full_name":"Marino, R A","first_name":"R A"},{"first_name":"G","full_name":"Pezzulli, G","last_name":"Pezzulli"},{"full_name":"Matthee, Jorryt J","orcid":"0000-0003-2871-127X","last_name":"Matthee","id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J"},{"first_name":"S D","last_name":"Johnson","full_name":"Johnson, S D"},{"first_name":"M","last_name":"Krumpe","full_name":"Krumpe, M"},{"first_name":"T","full_name":"Urrutia, T","last_name":"Urrutia"},{"full_name":"Kollatschny, W","last_name":"Kollatschny","first_name":"W"}],"title":"Probing the AGN unification model at redshift z ∼ 3 with MUSE observations of giant Lyα nebulae","citation":{"ama":"den Brok JS, Cantalupo S, Mackenzie R, et al.

Here, we study the X-ray and radio properties of ∼4000 LAEs at 2.2 < z < 6 from the SC4K survey in the COSMOS field. We detect 254 (6.8per cent±0.4per cent) LAEs individually in the X-rays (S/N > 3) with an average luminosity of 1044.31±0.01ergs−1 and average black hole accretion rate (BHAR) of 0.72±0.01 M⊙ yr−1, consistent with moderate to high accreting active galactic neuclei (AGNs). We detect 120 sources in deep radio data (radio AGN fraction of 3.2per cent±0.3per cent). The global AGN fraction (8.6per cent±0.4per cent) rises with Ly α luminosity and declines with increasing redshift. For X-ray-detected LAEs, Ly α luminosities correlate with the BHARs, suggesting that Ly α luminosity becomes a BHAR indicator. Most LAEs (93.1per cent±0.6per cent) at 2 < z < 6 have no detectable X-ray emission (BHARs < 0.017 M⊙ yr−1). The median star formation rate (SFR) of star-forming LAEs from Ly α and radio luminosities is 7.6+6.6−2.8 M⊙ yr−1. The black hole to galaxy growth ratio (BHAR/SFR) for LAEs is <0.0022, consistent with typical star-forming galaxies and the local BHAR/SFR relation. We conclude that LAEs at 2 < z < 6 include two different populations: an AGN population, where Ly α luminosity traces BHAR, and another with low SFRs which remain undetected in even the deepest X-ray stacks but is detected in the radio stacks.","lang":"eng"}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1909.11672"}],"month":"04","intvolume":" 493","publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"publication_status":"published","language":[{"iso":"eng"}],"volume":493,"issue":"3","citation":{"ieee":"J.

Asteroseismology is the most precise method of providing such information for field star populations en masse, but existing samples for the most part have been limited to a few narrow fields of view by the CoRoT and Kepler missions. In an effort to provide well-characterized stellar parameters across a wide range in Galactic position, we present the second data release of red giant asteroseismic parameters for the K2 Galactic Archaeology Program (GAP). We provide ${\\nu }_{\\max }$ and ${\\rm{\\Delta }}\\nu $ based on six independent pipeline analyses; first-ascent red giant branch (RGB) and red clump (RC) evolutionary state classifications from machine learning; and ready-to-use radius and mass coefficients, κR and κM, which, when appropriately multiplied by a solar-scaled effective temperature factor, yield physical stellar radii and masses. In total, we report 4395 radius and mass coefficients, with typical uncertainties of 3.3% (stat.) ± 1% (syst.) for κR and 7.7% (stat.) ± 2% (syst.) for κM among RGB stars, and 5.0% (stat.) ± 1% (syst.) for κR and 10.5% (stat.) ± 2% (syst.) for κM among RC stars. We verify that the sample is nearly complete—except for a dearth of stars with ${\\nu }_{\\max }\\lesssim 10\\mbox{--}20\\,\\mu \\mathrm{Hz}$—by comparing to Galactic models and visual inspection. Our asteroseismic radii agree with radii derived from Gaia Data Release 2 parallaxes to within 2.2% ± 0.3% for RGB stars and 2.0% ± 0.6% for RC stars.","lang":"eng"}],"extern":"1","date_updated":"2022-08-22T07:04:45Z","status":"public","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"type":"journal_article","article_type":"original","_id":"11610"},{"_id":"11611","article_type":"letter_note","type":"journal_article","keyword":["Astronomy and Astrophysics"],"status":"public","date_updated":"2022-08-22T07:08:29Z","extern":"1","abstract":[{"lang":"eng","text":"Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies1. Although these accreted stellar populations can be forensically identified as kinematically distinct structures within the Galaxy, it is difficult in general to date precisely the age at which any one merger occurred. Recent results have revealed a population of stars that were accreted via the collision of a dwarf galaxy, called Gaia–Enceladus1, leading to substantial pollution of the chemical and dynamical properties of the Milky Way. Here we identify the very bright, naked-eye star ν Indi as an indicator of the age of the early in situ population of the Galaxy. We combine asteroseismic, spectroscopic, astrometric and kinematic observations to show that this metal-poor, alpha-element-rich star was an indigenous member of the halo, and we measure its age to be 11.0±0.7 (stat) ±0.8 (sys) billion years. The star bears hallmarks consistent with having been kinematically heated by the Gaia–Enceladus collision. Its age implies that the earliest the merger could have begun was 11.6 and 13.2 billion years ago, at 68% and 95% confidence, respectively.

The launch of the NASA Transiting Exoplanet Survey Satellite (TESS) mission has enabled seismic-based inferences to go full sky—providing a clear advantage for large ensemble studies of the different Milky Way components. Here we demonstrate its potential for investigating the Galaxy by carrying out the first asteroseismic ensemble study of red giant stars observed by TESS. We use a sample of 25 stars for which we measure their global asteroseimic observables and estimate their fundamental stellar properties, such as radius, mass, and age. Significant improvements are seen in the uncertainties of our estimates when combining seismic observables from TESS with astrometric measurements from the Gaia mission compared to when the seismology and astrometry are applied separately. Specifically, when combined we show that stellar radii can be determined to a precision of a few percent, masses to 5%–10%, and ages to the 20% level. This is comparable to the precision typically obtained using end-of-mission Kepler data."}],"issue":"2","volume":889,"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"publication_status":"published","status":"public","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"type":"journal_article","article_type":"original","_id":"11612","extern":"1","date_updated":"2022-08-22T07:25:51Z","publisher":"IOP Publishing","quality_controlled":"1","oa":1,"acknowledgement":"This Letter includes data collected by the TESS mission, which are publicly available from the Mikulski Archive for Space Telescopes (MAST).

Stars more massive than ∼ 1.3 M⊙ are known to develop a convective core during the main-sequence: the dynamo process triggered by this convection could be the origin of a strong magnetic field inside the core of the star, trapped when it becomes stably stratified and for the rest of its evolution. The presence of highly magnetized white dwarfs strengthens the hypothesis of buried fossil magnetic fields inside the core of evolved low-mass stars. If such a fossil field exists, it should affect the mixed modes of red giants as they are sensitive to processes affecting the deepest layers of these stars. The impact of a magnetic field on dipolar oscillations modes was one of Pr. Michael J. Thompson’s research topics during the 90s when preparing the helioseismic SoHO space mission. As the detection of gravity modes in the Sun is still controversial, the investigation of the solar oscillation modes did not provide any hint of the existence of a magnetic field in the solar radiative core. Today we have access to the core of evolved stars thanks to the asteroseismic observation of mixed modes from CoRoT, Kepler, K2 and TESS missions. The idea of applying and generalizing the work done for the Sun came from discussions with Pr. Michael Thompson in early 2018 before we lost him. Following the path we drew together, we theoretically investigate the effect of a stable axisymmetric mixed poloidal and toroidal magnetic field, aligned with the rotation axis of the star, on the mixed modes frequencies of a typical evolved low-mass star. This enables us to estimate the magnetic perturbations to the eigenfrequencies of mixed dipolar modes, depending on the magnetic field strength and the evolutionary state of the star. We conclude that strong magnetic fields of ∼ 1MG should perturb the mixed-mode frequency pattern enough for its effects to be detectable inside current asteroseismic data."}],"oa_version":"Preprint","date_updated":"2022-08-22T08:07:42Z","extern":"1","type":"book_chapter","status":"public","_id":"11622","series_title":"ASSSP","page":"251-257","date_published":"2020-12-19T00:00:00Z","doi":"10.1007/978-3-030-55336-4_33","date_created":"2022-07-19T08:25:41Z","year":"2020","day":"19","publication":"Dynamics of the Sun and Stars","quality_controlled":"1","publisher":"Springer Nature","oa":1,"edition":"1","acknowledgement":"The authors of this work acknowledge the support received from the PLATO CNES grant, the National Aeronautics and Space Administration under Grant NNX15AF13G, by the National Science Foundation grant AST-1411685, the Ramon y Cajal fellowship number RYC-2015-17697, the ERC SPIRE grant (647383), and the Fundation L’Oréal-Unesco-Académie des sciences.","author":[{"id":"d9edb345-f866-11ec-9b37-d119b5234501","first_name":"Lisa Annabelle","orcid":"0000-0003-0142-4000","full_name":"Bugnet, Lisa Annabelle","last_name":"Bugnet"},{"full_name":"Prat, V.","last_name":"Prat","first_name":"V."},{"last_name":"Mathis","full_name":"Mathis, S.","first_name":"S."},{"first_name":"R.

Starting with the seminal work of Onak and Rubinfeld (in: Proceedings of the ACM symposium on theory of computing (STOC), 2010), this problem has received significant attention in recent years. Very recently, extending the framework of Baswana et al. (in: Proceedings of the IEEE symposium on foundations of computer science (FOCS), 2011) , Solomon (in: Proceedings of the IEEE symposium on foundations of computer science (FOCS), 2016) gave a randomized dynamic algorithm for this problem that has an approximation ratio of 2 and an amortized update time of O(1) with high probability. This algorithm requires the assumption of an oblivious adversary, meaning that the future sequence of edge insertions/deletions in the graph cannot depend in any way on the algorithm’s past output. A natural way to remove the assumption on oblivious adversary is to give a deterministic dynamic algorithm for the same problem in O(1) update time. In this paper, we resolve this question. We present a new deterministic fully dynamic algorithm that maintains a O(1)-approximate minimum vertex cover and maximum fractional matching, with an amortized update time of O(1). Previously, the best deterministic algorithm for this problem was due to Bhattacharya et al. (in: Proceedings of the ACM-SIAM symposium on discrete algorithms (SODA), 2015); it had an approximation ratio of (2+ε) and an amortized update time of O(logn/ε2). Our result can be generalized to give a fully dynamic O(f3)-approximate algorithm with O(f2) amortized update time for the hypergraph vertex cover and fractional hypergraph matching problem, where every hyperedge has at most f vertices.","lang":"eng"}],"volume":82,"issue":"4","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0178-4617"],"eissn":["1432-0541"]},"publication_status":"published","status":"public","keyword":["Dynamic algorithms","Data structures","Graph algorithms","Matching","Vertex cover"],"article_type":"original","type":"journal_article","_id":"11675","extern":"1","date_updated":"2022-09-12T08:55:46Z","quality_controlled":"1","publisher":"Springer Nature","oa":1,"date_published":"2020-04-01T00:00:00Z","doi":"10.1007/s00453-019-00630-4","date_created":"2022-07-27T14:31:06Z","page":"1057-1080","day":"01","publication":"Algorithmica","year":"2020","title":"Deterministic dynamic matching in O(1) update time","author":[{"first_name":"Sayan","full_name":"Bhattacharya, Sayan","last_name":"Bhattacharya"},{"last_name":"Chakrabarty","full_name":"Chakrabarty, Deeparnab","first_name":"Deeparnab"},{"id":"540c9bbd-f2de-11ec-812d-d04a5be85630","first_name":"Monika H","last_name":"Henzinger","orcid":"0000-0002-5008-6530","full_name":"Henzinger, Monika H"}],"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Bhattacharya S, Chakrabarty D, Henzinger MH. 2020.

A weighted set C_w that is a subset of the input is an ε-coreset if the cost of any feasible solution S with respect to C_w is within [1±ε] of the cost of S with respect to the original input. We give a very general technique to compute coresets in the fully-dynamic setting where input points can be added or deleted. Given a static (i.e., not dynamic) ε-coreset-construction algorithm that runs in time t(n, ε, λ) and computes a coreset of size s(n, ε, λ), where n is the number of input points and 1-λ is the success probability, we give a fully-dynamic algorithm that computes an ε-coreset with worst-case update time O((log n) ⋅ t(s(n, ε/log n, λ/n), ε/log n, λ/n)) (this bound is stated informally), where the success probability is 1-λ. Our technique is a fully-dynamic analog of the merge-and-reduce technique, which is due to Har-Peled and Mazumdar [Har-Peled and Mazumdar, 2004] and is based on a technique of Bentley and Saxe [Jon Louis Bentley and James B. Saxe, 1980], that applies to the insertion-only setting where points can only be added. Although, our space usage is O(n), our technique works in the presence of an adaptive adversary, and we show that Ω(n) space is required when adversary is adaptive.\r\nAs a concrete implication of our technique, using the result of Braverman et al. [{Braverman} et al., 2016], we get fully-dynamic ε-coreset-construction algorithms for k-median and k-means with worst-case update time O(ε^{-2} k² log⁵ n log³ k) and coreset size O(ε^{-2} k log n log² k) ignoring log log n and log(1/ε) factors and assuming that ε = Ω(1/poly(n)) and λ = Ω(1/poly(n)) (which are very weak assumptions made only to make these bounds easy to parse). This results in the first fully-dynamic constant-approximation algorithms for k-median and k-means with update times O(poly(k, log n, ε^{-1})). Specifically, the dependence on k is only quadratic, and the bounds are worst-case. The best previous bound for both problems was amortized O(nlog n) by Cohen-Addad et al. [Cohen-Addad et al., 2019] via randomized O(1)-coresets in O(n) space.\r\nWe also show that under the OMv conjecture [Monika Henzinger et al., 2015], a fully-dynamic (4 - δ)-approximation algorithm for k-means must either have an amortized update time of Ω(k^{1-γ}) or amortized query time of Ω(k^{2 - γ}), where γ > 0 is a constant.","lang":"eng"}],"intvolume":" 173","month":"08","main_file_link":[{"open_access":"1","url":"https://doi.org/10.4230/LIPIcs.ESA.2020.57"}],"alternative_title":["LIPIcs"],"scopus_import":"1"},{"year":"2020","publication":"8th Annual European Symposium on Algorithms","day":"26","date_created":"2022-08-12T07:13:25Z","date_published":"2020-08-26T00:00:00Z","doi":"10.4230/LIPIcs.ESA.2020.58","oa":1,"publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","quality_controlled":"1","citation":{"chicago":"Henzinger, Monika H, Khan Shahbaz, Richard Paul, and Christian Schulz. “Dynamic Matching Algorithms in Practice.” In 8th Annual European Symposium on Algorithms, Vol. 173.

The problem has been thoroughly investigated in theory and many specialized algorithms for solving it have been proposed in the last decades. In two large studies [Frigioni ea, 2001; Krommidas and Zaroliagis, 2008], a number of these algorithms have been evaluated experimentally against simple, static algorithms for graph traversal, showing the competitiveness and even superiority of the simple algorithms in practice, except for very dense random graphs or very high ratios of queries. A major drawback of those studies is that only small and mostly randomly generated graphs are considered.\r\nIn this paper, we engineer new algorithms to maintain all-pairs reachability information which are simple and space-efficient. Moreover, we perform an extensive experimental evaluation on both generated and real-world instances that are several orders of magnitude larger than those in the previous studies. Our results indicate that our new algorithms outperform all state-of-the-art algorithms on all types of input considerably in practice.","lang":"eng"}],"volume":160,"language":[{"iso":"eng"}],"publication_identifier":{"issn":["1868-8969"],"isbn":["9783959771481"]},"publication_status":"published","status":"public","type":"conference","conference":{"name":"SEA: Symposium on Experimental Algorithms","location":"Pisa, Italy","end_date":"2020-09-09","start_date":"2020-09-07"},"_id":"11822","extern":"1","date_updated":"2023-02-14T09:58:42Z"},{"date_updated":"2023-02-14T10:03:43Z","extern":"1","conference":{"name":"STACS: Symposium on Theoretical Aspects of Computer Science","start_date":"2020-03-10","end_date":"2020-03-13","location":"Montpellier, France"},"type":"conference","status":"public","_id":"11825","volume":154,"publication_status":"published","publication_identifier":{"isbn":["9783959771405"],"issn":["1868-8969"]},"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.4230/LIPIcs.STACS.2020.53","open_access":"1"}],"alternative_title":["LIPIcs"],"scopus_import":"1","intvolume":" 154","month":"03","abstract":[{"lang":"eng","text":"We give a fully dynamic (Las-Vegas style) algorithm with constant expected amortized time per update that maintains a proper (Δ+1)-vertex coloring of a graph with maximum degree at most Δ.

In particular, we develop a technique that, given any problem that admits a certain notion of vertex sparsifiers, gives data structures that maintain approximate solutions in sub-linear update and query time. We illustrate the applicability of our paradigm to the following problems. (1)A fully-dynamic algorithm that approximates all-pair maximum-flows/minimum-cuts up to a nearly logarithmic factor in O~(n2/3) 11The O~(⋅) notation is used in this paper to hide poly-logarithmic factors. amortized time against an oblivious adversary, and O~(m3/4) time against an adaptive adversary. (2)An incremental data structure that maintains O(1) - approximate shortest path in no(1) time per operation, as well as fully dynamic approximate all-pair shortest path and transshipment in O~(n2/3+o(1)) amortized time per operation. (3)A fully-dynamic algorithm that approximates all-pair effective resistance up to an (1+ϵ) factor in O~(n2/3+o(1)ϵ−O(1)) amortized update time per operation. The key tool behind result (1) is the dynamic maintenance of an algorithmic construction due to Madry [FOCS' 10], which partitions a graph into a collection of simpler graph structures (known as j-trees) and approximately captures the cut-flow and metric structure of the graph. The O(1)-approximation guarantee of (2) is by adapting the distance oracles by [Thorup-Zwick JACM '05]. Result (3) is obtained by invoking the random-walk based spectral vertex sparsifier by [Durfee et al. STOC '19] in a hierarchical manner, while carefully keeping track of the recourse among levels in the hierarchy.

It is one of the most fundamental problems on graphs and appears directly or indirectly in many and varied applications. While there has been theoretical work on this problem, showing both linear conditional lower bounds for the fully dynamic problem and insertions-only and deletions-only upper bounds beating these conditional lower bounds, there has been no experimental study that compares the performance of fully dynamic reachability algorithms in practice. Previous experimental studies in this area concentrated only on the more general all-pairs reachability or transitive closure problem and did not use real-world dynamic graphs.\r\n\r\nIn this paper, we bridge this gap by empirically studying an extensive set of algorithms for the single-source reachability problem in the fully dynamic setting. In particular, we design several fully dynamic variants of well-known approaches to obtain and maintain reachability information with respect to a distinguished source. Moreover, we extend the existing insertions-only or deletions-only upper bounds into fully dynamic algorithms. Even though the worst-case time per operation of all the fully dynamic algorithms we evaluate is at least linear in the number of edges in the graph (as is to be expected given the conditional lower bounds) we show in our extensive experimental evaluation that their performance differs greatly, both on generated as well as on real-world instances."}],"month":"01","scopus_import":"1","quality_controlled":"1","publisher":"Society for Industrial and Applied Mathematics","main_file_link":[{"url":"https://arxiv.org/abs/1905.01216","open_access":"1"}],"oa":1},{"date_created":"2022-08-17T06:47:40Z","doi":"10.1137/1.9781611976007.4","date_published":"2020-01-01T00:00:00Z","page":"42-55","publication":"2020 Symposium on Algorithm Engineering and Experiments","language":[{"iso":"eng"}],"day":"01","year":"2020","publication_status":"published","publication_identifier":{"eisbn":["978-1-61197-600-7"]},"month":"01","oa":1,"main_file_link":[{"url":"https://arxiv.org/abs/1908.04141","open_access":"1"}],"publisher":"Society for Industrial and Applied Mathematics","quality_controlled":"1","scopus_import":"1","oa_version":"Preprint","abstract":[{"lang":"eng","text":"We introduce the fastest known exact algorithm for the multiterminal cut problem with k terminals.

In this work we study vertex sparsifiers, i.e., sparsifiers whose goal is to reduce the number of vertices. We focus on the following notions: (1) Given a digraph 𝐺=(𝑉,𝐸) and terminal vertices 𝐾⊂𝑉 with |𝐾|=𝑘, a (vertex) reachability sparsifier of 𝐺 is a digraph 𝐻=(𝑉𝐻,𝐸𝐻), 𝐾⊂𝑉𝐻 that preserves all reachability information among terminal pairs. Let |𝑉𝐻| denote the size of 𝐻. In this work we introduce the notion of reachability-preserving minors (RPMs), i.e., we require 𝐻 to be a minor of 𝐺. We show any directed graph 𝐺 admits an RPM 𝐻 of size 𝑂(𝑘3), and if 𝐺 is planar, then the size of 𝐻 improves to 𝑂(𝑘2log𝑘). We complement our upper bound by showing that there exists an infinite family of grids such that any RPM must have Ω(𝑘2) vertices. (2) Given a weighted undirected graph 𝐺=(𝑉,𝐸) and terminal vertices 𝐾 with |𝐾|=𝑘, an exact (vertex) cut sparsifier of 𝐺 is a graph 𝐻 with 𝐾⊂𝑉𝐻 that preserves the value of minimum cuts separating any bipartition of 𝐾. We show that planar graphs with all the 𝑘 terminals lying on the same face admit exact cut sparsifiers of size 𝑂(𝑘2) that are also planar. Our result extends to flow and distance sparsifiers. It improves the previous best-known bound of 𝑂(𝑘222𝑘) for cut and flow sparsifiers by an exponential factor and matches an Ω(𝑘2) lower-bound for this class of graphs."}],"oa_version":"Preprint","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1702.01136"}],"scopus_import":"1","intvolume":" 34","month":"01","date_updated":"2023-02-21T16:29:44Z","extern":"1","_id":"11894","type":"journal_article","article_type":"original","status":"public"},{"citation":{"mla":"Reischauer, Susanne, et al. “Modular, Self-Assembling Metallaphotocatalyst for Cross-Couplings Using the Full Visible-Light Spectrum.” ACS Catalysis, vol. 10, no. 22, American Chemical Society, 2020, pp. 13269–13274, doi:10.1021/acscatal.0c03950.","ama":"Reischauer S, Strauss V, Pieber B.

These protocols rely on a few photocatalysts that can only convert a small portion of visible light (<500 nm) into chemical energy. The high-energy photons that excite the photocatalyst can result in unwanted side reactions. Dyes that absorb a much broader spectrum of light are not applicable because of their short-lived singlet excited states. Here, we describe a self-assembling catalyst system that overcomes this limitation. Immobilization of a nickel catalyst on dye-sensitized titanium dioxide results in a material that catalyzes carbon–heteroatom and carbon–carbon bond formations. The modular approach of dye-sensitized metallaphotocatalysts accesses the entire visible light spectrum and allows tackling selectivity issues resulting from low wavelengths strategically. The concept overcomes current limitations of metallaphotocatalysis by unlocking the potential of dyes that were previously unsuitable.","lang":"eng"}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.26434/chemrxiv.12444908","open_access":"1"}],"month":"11","intvolume":" 10","publication_identifier":{"eissn":["2155-5435"]},"publication_status":"published","language":[{"iso":"eng"}],"issue":"22","volume":10},{"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/ejoc.201901173"}],"scopus_import":"1","intvolume":" 2020","month":"03","abstract":[{"text":"Photochemistry enables new synthetic means to form carbon–heteroatom bonds.

We report a comprehensive kinetic examination of a model carboxylate O-arylation, comparing a state-of-the-art homogeneous photocatalyst (Ir(ppy)3) with a competitive heterogeneous photocatalyst (graphitic carbon nitride). Experimental conditions were adjusted such that the nickel catalytic cycle is saturated with excited photocatalyst. This approach was designed to remove the role of the photocatalyst, by which only the intrinsic behaviors of the nickel catalytic cycles are observed. The two reactions did not display identical kinetics. Ir(ppy)3 deactivates the nickel catalytic cycle and creates more dehalogenated side product. Kinetic data for the reaction using Ir(ppy)3 supports a turnover-limiting reductive elimination. Graphitic carbon nitride gave higher selectivity, even at high photocatalyst-to-nickel ratios. The heterogeneous reaction also showed a rate dependence on aryl halide, indicating that oxidative addition plays a role in rate determination. The results argue against the current mechanistic hypothesis, which states that the photocatalyst is only involved to trigger reductive elimination.","lang":"eng"}],"oa_version":"Published Version","pmid":1,"volume":142,"issue":"25","publication_identifier":{"eissn":["1520-5126"],"issn":["0002-7863"]},"publication_status":"published","language":[{"iso":"eng"}],"author":[{"first_name":"Jamal A.","last_name":"Malik","full_name":"Malik, Jamal A."},{"first_name":"Amiera","last_name":"Madani","full_name":"Madani, Amiera"},{"id":"93e5e5b2-0da6-11ed-8a41-af589a024726","first_name":"Bartholomäus","last_name":"Pieber","orcid":"0000-0001-8689-388X","full_name":"Pieber, Bartholomäus"},{"last_name":"Seeberger","full_name":"Seeberger, Peter H.","first_name":"Peter H."}],"external_id":{"pmid":["32469219"]},"article_processing_charge":"No","title":"Evidence for photocatalyst involvement in oxidative additions of nickel-catalyzed carboxylate O-arylations","citation":{"chicago":"Malik, Jamal A., Amiera Madani, Bartholomäus Pieber, and Peter H.

Performing these transformations on larger scales using a continuous process is difficult due to the problems associated with handling solids in flow. By combining an oscillatory pump with a microstructured plug flow photoreactor, a stable suspension of the photocatalyst can be maintained, circumventing clogging of the reactor channels. Through careful tuning of the oscillator properties, the residence time distribution (RTD) was optimized, whilst maintaining a stable catalyst suspension. Short residence times (20 min) were achieved using optimized conditions and the recyclability of the photocatalyst was demonstrated over 10 cycles with no loss of activity. During a stable 4.5 hour scale-out demonstration, the model substrate could be isolated on 12 g scale (90% yield, 2.67 g h−1). Moreover, the method was applied for the gram scale synthesis of an intermediate of the active pharmaceutical ingredient tetracaine.","lang":"eng"}]},{"publisher":"American Association for the Advancement of Science","quality_controlled":"1","oa":1,"year":"2020","day":"06","publication":"Science Advances","doi":"10.1126/sciadv.aaz4074","date_published":"2020-03-06T00:00:00Z","date_created":"2019-11-19T14:01:10Z","article_number":"eaaz4074","citation":{"chicago":"Ghosh, Sayak, Michael Matty, Ryan Baumbach, Eric D.

We observe no anomalies in the shear elastic moduli, providing strong thermodynamic evidence for a one-component order parameter. We develop a machine learning framework that reaches this conclusion directly from the raw data, even in a crystal that is too small for traditional resonant ultrasound.

We further derive a prescriptive approach to avoid this performance degradation, as well as algorithmic insights on optimistic BST design. Our work underlines the gap between the theory and practice of multi-core performance, and calls for further research to help bridge this gap.","lang":"eng"}]},{"title":"The evolutionary price of anarchy: Locally bounded agents in a dynamic virus game","external_id":{"arxiv":["1906.00110"]},"article_processing_charge":"No","author":[{"id":"38B437DE-F248-11E8-B48F-1D18A9856A87","first_name":"Laura","last_name":"Schmid","orcid":"0000-0002-6978-7329","full_name":"Schmid, Laura"},{"first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee"},{"first_name":"Stefan","last_name":"Schmid","full_name":"Schmid, Stefan"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Schmid L, Chatterjee K, Schmid S. 2020.

Leaving agents to selfishly optimize comes with the risk of ending up in sub-optimal states (in terms of performance and/or costs), compared to a centralized system design. However, the PoA relies on strong assumptions about agents' rationality (e.g., resources and information) and interactions, whereas in many distributed systems agents interact locally with bounded resources. They do so repeatedly over time (in contrast to \"one-shot games\"), and their strategies may evolve. Using a more realistic evolutionary game model, this paper introduces a realized evolutionary Price of Anarchy (ePoA). The ePoA allows an exploration of equilibrium selection in dynamic distributed systems with multiple equilibria, based on local interactions of simple memoryless agents. Considering a fundamental game related to virus propagation on networks, we present analytical bounds on the ePoA in basic network topologies and for different strategy update dynamics. In particular, deriving stationary distributions of the stochastic evolutionary process, we find that the Nash equilibria are not always the most abundant states, and that different processes can feature significant off-equilibrium behavior, leading to a significantly higher ePoA compared to the PoA studied traditionally in the literature.

For example, the performance of a web server may be monitored based on the ratio of the total count of requests from the least and most active clients. Exact frequency monitoring, however, can be prohibitively expensive; in the above example it would require as many counters as there are clients. In this paper, we propose the efficient probabilistic monitoring of common frequency properties, including the mode (i.e., the most common event) and the median of an event sequence. We define a logic to express composite frequency properties as a combination of atomic frequency properties. Our main contribution is an algorithm that, under suitable probabilistic assumptions, can be used to monitor these important frequency properties with four counters, independent of the number of different events. Our algorithm samples longer and longer subwords of an infinite event sequence. We prove the almost-sure convergence of our algorithm by generalizing ergodic theory from increasing-length prefixes to increasing-length subwords of an infinite sequence. A similar algorithm could be used to learn a connected Markov chain of a given structure from observing its outputs, to arbitrary precision, for a given confidence.

The nematode Caenorhabditis elegans, owing to its compact translucent nervous system, is a powerful system in which to study conserved aspects of the development and plasticity of neuronal morphology. Here we focus on one pair of sensory neurons, termed URX, which the worm uses to sense and avoid high levels of environmental oxygen. Previous studies have reported that the URX neuron pair has variable branched endings at its dendritic sensory tip. By controlling oxygen levels and analyzing mutants, we found that these microtubule-rich branched endings grow over time as a consequence of neuronal activity in adulthood. We also find that the growth of these branches correlates with an increase in cellular sensitivity to particular ranges of oxygen that is observable in the behavior of older worms. Given the strengths of C. elegans as a model organism, URX may serve as a potent system for uncovering genes and mechanisms involved in activity-dependent morphological changes in neurons and possible adaptive changes in the aging nervous system."}],"month":"05","intvolume":" 461","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1101/685339"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["0012-1606"]},"publication_status":"published","volume":461,"issue":"1","_id":"7545","status":"public","type":"journal_article","article_type":"original","extern":"1","date_updated":"2021-01-12T08:14:06Z"},{"publication":"Mathematics in Computer Science","day":"01","year":"2020","has_accepted_license":"1","date_created":"2020-03-05T13:30:18Z","doi":"10.1007/s11786-020-00461-5","date_published":"2020-03-01T00:00:00Z","page":"141-176","oa":1,"publisher":"Springer Nature","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Choudhary, Aruni, et al. “Coxeter Triangulations Have Good Quality.” Mathematics in Computer Science, vol. 14, Springer Nature, 2020, pp. 141–76, doi:10.1007/s11786-020-00461-5.","apa":"Choudhary, A., Kachanovich, S., & Wintraecken, M.

In the regime of small spin-orbit coupling with regard to the spin-orbital exchange, the ground state to a large extent resembles the one obtained in the limit of vanishing spin-orbit coupling. On the other hand, for large spin-orbit coupling the ground state can, depending on the model parameters, either still show negligible spin-orbital entanglement or evolve to a highly spin-orbitally-entangled phase with completely distinct properties that are described by an effective XXZ model. The presented results suggest that (i) the spin-orbital entanglement may be induced by large on-site spin-orbit coupling, as found in the 5d transition metal oxides, such as the iridates; (ii) for Mott insulators with weak spin-orbit coupling of Ising type, such as, e.g., the alkali hyperoxides, the effects of the spin-orbit coupling on the ground state can, in the first order of perturbation theory, be neglected."}],"oa_version":"Published Version","file_date_updated":"2020-07-14T12:48:00Z","department":[{"_id":"MiLe"}],"date_updated":"2021-01-12T08:14:23Z","ddc":["530"],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"journal_article","article_type":"original","status":"public","_id":"7594"},{"has_accepted_license":"1","year":"2020","day":"01","publication":"23rd International Conference on Principles of Distributed Systems","page":"15:1-15:16","date_published":"2020-02-01T00:00:00Z","doi":"10.4230/LIPIcs.OPODIS.2019.15","date_created":"2020-03-22T23:00:46Z","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","quality_controlled":"1","oa":1,"citation":{"mla":"Alistarh, Dan-Adrian, et al. “In Search of the Fastest Concurrent Union-Find Algorithm.” 23rd International Conference on Principles of Distributed Systems, vol. 153, Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2020, p. 15:1-15:16, doi:10.4230/LIPIcs.OPODIS.2019.15.","ieee":"D.-A.

Recently, there has been mounting interest in analyzing this problem in the concurrent scenario, and several asymptotically-efficient algorithms have been proposed. Yet, to date, there is very little known about the practical performance of concurrent Union-Find. This work addresses this gap. We evaluate and analyze the performance of several concurrent Union-Find algorithms and optimization strategies across a wide range of platforms (Intel, AMD, and ARM) and workloads (social, random, and road networks, as well as integrations into more complex algorithms). We first observe that, due to the limited computational cost, the number of induced cache misses is the critical determining factor for the performance of existing algorithms. We introduce new techniques to reduce this cost by storing node priorities implicitly and by using plain reads and writes in a way that does not affect the correctness of the algorithms. Finally, we show that Union-Find implementations are an interesting application for Transactional Memory (TM): one of the fastest algorithm variants we discovered is a sequential one that uses coarse-grained locking with the lock elision optimization to reduce synchronization cost and increase scalability.

The PD biogenesis is an intriguing but poorly understood process. By expressing an Arabidopsis remorin protein in mammalian cells, we have reconstituted a PD-like filamentous structure, termed remorin filament (RF), connecting neighboring cells physically and physiologically. Notably, RFs are capable of transporting macromolecules intercellularly, in a way similar to plant PD. With further super-resolution microscopic analysis and biochemical characterization, we found that RFs are also composed of actin filaments, forming the core skeleton structure, aligned with the remorin protein. This unique heterologous filamentous structure might explain the molecular mechanism for remorin function as well as PD construction. Furthermore, remorin protein exhibits a specific distribution manner in the plasma membrane in mammalian cells, representing a lipid nanodomain, depending on its lipid modification status. Our studies not only provide crucial insights into the mechanism of PD biogenesis, but also uncovers unsuspected fundamental mechanistic and evolutionary links between intercellular communication systems of plants and animals."}],"oa_version":"Preprint","oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1101/791137"}],"publisher":"Cold Spring Harbor Laboratory","month":"02","citation":{"mla":"Wei, Zhuang, et al. “Plasmodesmata-like Intercellular Connections by Plant Remorin in Animal Cells.” BioRxiv, Cold Spring Harbor Laboratory, 2020, doi:10.1101/791137.","ama":"Wei Z, Tan S, Liu T, et al.

We demonstrate the utility of this approach, and compare it to the geometric morphometric approach, using a large set of Littorina saxatilis shells in which locally adapted populations differ in shape.

Here we propose a maximum likelihood method to estimate the contribution of GxE to continuous traits taking into account all interacting environmental variables, without the need to measure any. Extensive simulations demonstrate that our method provides unbiased interaction estimates and excellent coverage. We also offer strategies to distinguish specific GxE from general scale effects. Applying our method to 32 traits in the UK Biobank reveals that while the genetic risk score (GRS) of 376 variants explains 5.2% of body mass index (BMI) variance, GRSxE explains an additional 1.9%. Nevertheless, this interaction holds for any variable with identical correlation to BMI as the GRS, hence may not be GRS-specific. Still, we observe that the global contribution of specific GRSxE to complex traits is substantial for nine obesity-related measures (including leg impedance and trunk fat-free mass).","lang":"eng"}],"oa_version":"Published Version"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Kimchi, Ofer, Carl Peter Goodrich, Alexis Courbet, Agnese I.

We construct mathematical models for two posttranslational oscillators, using few components that interact only through reversible binding and phosphorylation/dephosphorylation reactions. Our designed oscillators rely on the self-assembly of two protein species into multimeric functional enzymes that respectively inhibit and enhance this self-assembly. We limit our analysis to within experimental constraints, finding (i) significant portions of the restricted parameter space yielding oscillations and (ii) that oscillation periods can be tuned by several orders of magnitude using recent advances in computational protein design.

(PODC'19), and significantly improves upon the state-of-the-art O(logΔ)-round deterministic (Δ+1)-coloring bound of Parter (ICALP'18).\r\nA remarkable property of our algorithm is its simplicity. Whereas the state-of-the-art randomized algorithms for this problem are based on the quite involved local coloring algorithm of Chang et al. (STOC'18), our algorithm can be described in just a few lines. At a high level, it applies a careful derandomization of a recursive procedure which partitions the nodes and their respective palettes into separate bins. We show that after O(1) recursion steps, the remaining uncolored subgraph within each bin has linear size, and thus can be solved locally by collecting it to a single node. This algorithm can also be implemented in the Massively Parallel Computation (MPC) model provided that each machine has linear (in n, the number of nodes in the input graph) space.\r\nWe also show an extension of our algorithm to the MPC regime in which machines have sublinear space: we present the first deterministic (Δ+1)-list coloring algorithm designed for sublinear-space MPC, which runs in O(logΔ+loglogn) rounds."}],"oa_version":"Submitted Version","month":"07","publication_status":"published","file":[{"date_created":"2020-10-08T08:17:36Z","file_name":"ColoringArxiv.pdf","date_updated":"2020-10-08T08:17:36Z","file_size":520051,"creator":"pdavies","checksum":"46fe4fc58a64eb04068115573f631d4c","file_id":"8624","success":1,"content_type":"application/pdf","access_level":"open_access","relation":"main_file"}],"language":[{"iso":"eng"}],"ec_funded":1},{"doi":"10.1137/1.9781611975994.47","date_published":"2020-01-01T00:00:00Z","date_created":"2020-05-10T22:00:48Z","page":"767-785","day":"01","publication":"Proceedings of the Annual ACM-SIAM Symposium on Discrete Algorithms","year":"2020","quality_controlled":"1","publisher":"SIAM","oa":1,"title":"Embeddability of simplicial complexes is undecidable","author":[{"last_name":"Filakovský","full_name":"Filakovský, Marek","first_name":"Marek","id":"3E8AF77E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Wagner, Uli","orcid":"0000-0002-1494-0568","last_name":"Wagner","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","first_name":"Uli"},{"full_name":"Zhechev, Stephan Y","last_name":"Zhechev","first_name":"Stephan Y","id":"3AA52972-F248-11E8-B48F-1D18A9856A87"}],"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Filakovský, Marek, et al. “Embeddability of Simplicial Complexes Is Undecidable.” Proceedings of the Annual ACM-SIAM Symposium on Discrete Algorithms, vol. 2020–January, SIAM, 2020, pp. 767–85, doi:10.1137/1.9781611975994.47.","ama":"Filakovský M, Wagner U, Zhechev SY.

This movement is setting the groundwork for a revolution, allowing scientific equipment to be sourced at a fraction of the cost and has the potential to increase the availability of equipment for scientists around the world. Science education is increasingly recognized as another channel for science diplomacy. In this perspective, we introduce the idea that the Maker movement and open-source technologies have the potential to revolutionize science, technology, engineering and mathematics (STEM) education worldwide.

SCOPES is self-contained, independent of local resources, and cost-effective. SCOPES can be adapted to communicate complex subjects from genetics to neurobiology, perform real-world biological experiments and explore digitized scientific samples. We envision such platforms will enhance science diplomacy by providing a means for scientists to share their findings with classrooms and for educators to incorporate didactic concepts into STEM lessons. By providing students the opportunity to design, perform, and share scientific experiments, students also experience firsthand the benefits of a multinational scientific community.

More precisely, we consider a two-level system for electrons and holes which is augmented by an intermediate energy level for electrons in so-called trapped states. The recombination dynamics use the mass action principle by taking into account this additional trap level. The main part of the paper is concerned with the derivation of an entropy–entropy production inequality, which entails exponential convergence to the equilibrium via the so-called entropy method. The novelty of our approach lies in the fact that the entropy method is applied uniformly in a fast-reaction parameter which governs the lifetime of electrons on the trap level. Thus, the resulting decay estimate for the densities of electrons and holes extends to the corresponding quasi-steady-state approximation.","lang":"eng"}],"oa_version":"Published Version","volume":6,"publication_identifier":{"eissn":["22969039"],"issn":["22969020"]},"publication_status":"published","file":[{"relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"file_id":"8802","checksum":"6bc6832caacddceee1471291e93dcf1d","creator":"dernst","file_size":8408694,"date_updated":"2020-11-25T08:59:59Z","file_name":"2020_JourEllipticParabEquat_Fellner.pdf","date_created":"2020-11-25T08:59:59Z"}],"language":[{"iso":"eng"}],"article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","_id":"7866","file_date_updated":"2020-11-25T08:59:59Z","department":[{"_id":"JuFi"}],"date_updated":"2021-01-12T08:15:47Z","ddc":["510"],"quality_controlled":"1","publisher":"Springer Nature","oa":1,"acknowledgement":"Open access funding provided by Austrian Science Fund (FWF).

Our process, which we call homotopic curve shortening (HCS), starts with a closed curve (which might self-intersect) in the presence of a set P⊂ ℝ² of point obstacles, and evolves in discrete steps, where each step consists of (1) taking shortcuts around the obstacles, and (2) reducing the curve to its shortest homotopic equivalent. We find experimentally that, if the initial curve is held fixed and P is chosen to be either a very fine regular grid or a uniformly random point set, then HCS behaves at the limit like the affine curve-shortening flow (ACSF). This connection between HCS and ACSF generalizes the link between \"grid peeling\" and the ACSF observed by Eppstein et al. (2017), which applied only to convex curves, and which was studied only for regular grids. We prove that HCS satisfies some properties analogous to those of ACSF: HCS is invariant under affine transformations, preserves convexity, and does not increase the total absolute curvature. Furthermore, the number of self-intersections of a curve, or intersections between two curves (appropriately defined), does not increase. Finally, if the initial curve is simple, then the number of inflection points (appropriately defined) does not increase.","lang":"eng"}],"intvolume":" 164","month":"06","alternative_title":["LIPIcs"],"scopus_import":"1","language":[{"iso":"eng"}],"file":[{"checksum":"6872df6549142f709fb6354a1b2f2c06","file_id":"8007","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_name":"2020_LIPIcsSoCG_Avvakumov.pdf","date_created":"2020-06-23T11:13:49Z","creator":"dernst","file_size":575896,"date_updated":"2020-07-14T12:48:06Z"}],"publication_status":"published","publication_identifier":{"issn":["18688969"],"isbn":["9783959771436"]},"volume":164,"_id":"7991","status":"public","tmp":{"short":"CC BY (3.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/3.0/legalcode","name":"Creative Commons Attribution 3.0 Unported (CC BY 3.0)"},"conference":{"name":"SoCG: Symposium on Computational Geometry","end_date":"2020-06-26","location":"Zürich, Switzerland","start_date":"2020-06-22"},"type":"conference","ddc":["510"],"date_updated":"2021-01-12T08:16:23Z","file_date_updated":"2020-07-14T12:48:06Z","department":[{"_id":"UlWa"}]},{"language":[{"iso":"eng"}],"file":[{"date_created":"2020-06-23T06:56:23Z","file_name":"2020_LIPIcsSoCG_Patakova_61.pdf","creator":"dernst","date_updated":"2020-07-14T12:48:06Z","file_size":645421,"checksum":"d0996ca5f6eb32ce955ce782b4f2afbe","file_id":"8005","access_level":"open_access","relation":"main_file","content_type":"application/pdf"}],"publication_status":"published","publication_identifier":{"isbn":["9783959771436"],"issn":["18688969"]},"volume":164,"oa_version":"Published Version","abstract":[{"lang":"eng","text":"We prove general topological Radon-type theorems for sets in ℝ^d, smooth real manifolds or finite dimensional simplicial complexes. Combined with a recent result of Holmsen and Lee, it gives fractional Helly theorem, and consequently the existence of weak ε-nets as well as a (p,q)-theorem. More precisely: Let X be either ℝ^d, smooth real d-manifold, or a finite d-dimensional simplicial complex. Then if F is a finite, intersection-closed family of sets in X such that the ith reduced Betti number (with ℤ₂ coefficients) of any set in F is at most b for every non-negative integer i less or equal to k, then the Radon number of F is bounded in terms of b and X. Here k is the smallest integer larger or equal to d/2 - 1 if X = ℝ^d; k=d-1 if X is a smooth real d-manifold and not a surface, k=0 if X is a surface and k=d if X is a d-dimensional simplicial complex. Using the recent result of the author and Kalai, we manage to prove the following optimal bound on fractional Helly number for families of open sets in a surface: Let F be a finite family of open sets in a surface S such that the intersection of any subfamily of F is either empty, or path-connected. Then the fractional Helly number of F is at most three.

Given a point p in the interior of K, a hyperplane h passing through p is called barycentric if p is the barycenter of K ∩ h. In 1961, Grünbaum raised the question whether, for every K, there exists an interior point p through which there are at least n+1 distinct barycentric hyperplanes. Two years later, this was seemingly resolved affirmatively by showing that this is the case if p=p₀ is the point of maximal depth in K. However, while working on a related question, we noticed that one of the auxiliary claims in the proof is incorrect. Here, we provide a counterexample; this re-opens Grünbaum’s question. It follows from known results that for n ≥ 2, there are always at least three distinct barycentric cuts through the point p₀ ∈ K of maximal depth. Using tools related to Morse theory we are able to improve this bound: four distinct barycentric cuts through p₀ are guaranteed if n ≥ 3.","lang":"eng"}],"oa_version":"Published Version","alternative_title":["LIPIcs"],"scopus_import":1,"intvolume":" 164","month":"06","publication_status":"published","publication_identifier":{"isbn":["9783959771436"],"issn":["18688969"]},"language":[{"iso":"eng"}],"file":[{"creator":"dernst","file_size":750318,"date_updated":"2020-07-14T12:48:06Z","file_name":"2020_LIPIcsSoCG_Patakova.pdf","date_created":"2020-06-23T06:45:52Z","relation":"main_file","access_level":"open_access","content_type":"application/pdf","checksum":"ce1c9194139a664fb59d1efdfc88eaae","file_id":"8004"}],"volume":164,"_id":"7992","conference":{"start_date":"2020-06-22","location":"Zürich, Switzerland","end_date":"2020-06-26","name":"SoCG: Symposium on Computational Geometry"},"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"conference","status":"public","date_updated":"2021-01-12T08:16:23Z","ddc":["510"],"department":[{"_id":"UlWa"}],"file_date_updated":"2020-07-14T12:48:06Z"},{"article_number":"9:1 - 9:14","project":[{"name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Arroyo Guevara, Alan M, Julien Bensmail, and R.

While thermalization in one-dimensional systems can often be suppressed by integrability mechanisms, in two spatial dimensions thermalization is expected to be far more effective due to the increased phase space. In this work we propose a general framework for escaping or delaying the emergence of the thermal state in two-dimensional arrays of Rydberg atoms via the mechanism of quantum scars, i.e., initial states that fail to thermalize. The suppression of thermalization is achieved in two complementary ways: by adding local perturbations or by adjusting the driving Rabi frequency according to the local connectivity of the lattice. We demonstrate that these mechanisms allow us to realize robust quantum scars in various two-dimensional lattices, including decorated lattices with nonconstant connectivity. In particular, we show that a small decrease of the Rabi frequency at the corners of the lattice is crucial for mitigating the strong boundary effects in two-dimensional systems. Our results identify synchronization as an important tool for future experiments on two-dimensional quantum scars.","lang":"eng"}],"intvolume":" 2","month":"06","ddc":["530"],"date_updated":"2021-01-12T08:16:30Z","department":[{"_id":"MaSe"}],"file_date_updated":"2020-07-14T12:48:08Z","_id":"8011","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","publication":"Physical Review Research","day":"22","year":"2020","has_accepted_license":"1","date_created":"2020-06-23T12:00:19Z","date_published":"2020-06-22T00:00:00Z","doi":"10.1103/physrevresearch.2.022065","oa":1,"publisher":"American Physical Society","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Michailidis A, Turner CJ, Papić Z, Abanin DA, Serbyn M. 2020.

These emergent features are typical of systems at the critical point of continuous phase transitions, and have led to the hypothesis that such systems may self-organize at criticality, i.e. without any fine tuning of parameters. Since the introduction of the Bak-Tang-Wiesenfeld (BTW) model, the paradigm of self-organized criticality (SOC) has been very fruitful for the analysis of emergent collective behaviors in a number of systems, including the brain. Although considerable effort has been devoted in identifying and modeling scaling features of burst and avalanche statistics, dynamical aspects related to the temporal organization of bursts remain often poorly understood or controversial. Of crucial importance to understand the mechanisms responsible for emergent behaviors is the relationship between active and quiet periods, and the nature of the correlations. Here we investigate the dynamics of active (θ-bursts) and quiet states (δ-bursts) in brain activity during the sleep-wake cycle. We show the duality of power-law (θ, active phase) and exponential-like (δ, quiescent phase) duration distributions, typical of SOC, jointly emerge with power-law temporal correlations and anti-correlated coupling between active and quiet states. Importantly, we demonstrate that such temporal organization shares important similarities with earthquake dynamics, and propose that specific power-law correlations and coupling between active and quiet states are distinctive characteristics of a class of systems with self-organization at criticality.","lang":"eng"}],"title":"Power-law correlations and coupling of active and quiet states underlie a class of complex systems with self-organization at criticality","article_processing_charge":"No","author":[{"first_name":"Fabrizio","id":"A057D288-3E88-11E9-986D-0CF4E5697425","full_name":"Lombardi, Fabrizio","orcid":"0000-0003-2623-5249","last_name":"Lombardi"},{"first_name":"Jilin W.J.L.","last_name":"Wang","full_name":"Wang, Jilin W.J.L."},{"full_name":"Zhang, Xiyun","last_name":"Zhang","first_name":"Xiyun"},{"last_name":"Ivanov","full_name":"Ivanov, Plamen Ch","first_name":"Plamen Ch"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Lombardi F, Wang JWJL, Zhang X, Ivanov PC.

This IgE-mediated disease can be treated with allergen immunotherapy (AIT), which typically gives rise to IgG antibodies inducing tolerance. Although the main mechanisms of allergen immunotherapy (AIT) are known, questions regarding possible Fc-mediated effects of IgG antibodies remain unanswered. This can mainly be attributed to the unavailability of appropriate tools, i.e., well-characterised recombinant antibodies (rAbs). We hereby aimed at providing human rAbs of several classes for mechanistic studies and as possible candidates for passive immunotherapy. We engineered IgE, IgG1, and IgG4 sharing the same variable region against the major birch pollen allergen Bet v 1 using Polymerase Incomplete Primer Extension (PIPE) cloning. We tested IgE functionality and IgG blocking capabilities using appropriate model cell lines. In vitro studies showed IgE engagement with FcεRI and CD23 and Bet v 1-dependent degranulation. Overall, we hereby present fully functional, human IgE, IgG1, and IgG4 sharing the same variable region against Bet v 1 and showcase possible applications in first mechanistic studies.

In this work, we achieve the best of both worlds by proposing a novel abstractions called the finality gadget. A finality gadget allows for transactions to always optimistically commit but informs the clients that these transactions might be unsafe. As a result, a blockchain can execute transactions optimistically and only commit them after they have been sufficiently and provably audited. In\r\nthis work, we formally model the finality gadget abstraction, prove that it is impossible to solve it deterministically in full asynchrony (even though it is stronger than consensus) and provide a partially synchronous protocol which is currently securing a major blockchain. This way we show that the protocol designer can decouple safety and liveness in order to speed up recovery from failures. We believe that there can be other types of finality gadgets that provide weaker safety (e.g., probabilistic) in order to gain more efficiency and this can depend on the probability that the network is not in synchrony."}],"oa_version":"Preprint","author":[{"full_name":"Stewart, Alistair","last_name":"Stewart","first_name":"Alistair"},{"first_name":"Eleftherios","id":"f5983044-d7ef-11ea-ac6d-fd1430a26d30","last_name":"Kokoris Kogias","full_name":"Kokoris Kogias, Eleftherios"}],"article_processing_charge":"No","external_id":{"arxiv":["2007.01560"]},"title":"GRANDPA: A Byzantine finality gadget","citation":{"ama":"Stewart A, Kokoris Kogias E.

In a nutshell: a reverse firewall is placed outside of a device and its goal is to “sanitize” the messages sent by it, in such a way that a malicious device cannot leak its secrets to the outside world. It is typically assumed that the cryptographic devices are attacked in a “functionality-preserving way” (i.e. informally speaking, the functionality of the protocol remains unchanged under this attacks). In their paper, Mironov and Stephens-Davidowitz construct a protocol for passively-secure two-party computations with firewalls, leaving extension of this result to stronger models as an open question.\r\nIn this paper, we address this problem by constructing a protocol for secure computation with firewalls that has two main advantages over the original protocol from Eurocrypt 2015. Firstly, it is a multiparty computation protocol (i.e. it works for an arbitrary number n of the parties, and not just for 2). Secondly, it is secure in much stronger corruption settings, namely in the active corruption model. More precisely: we consider an adversary that can fully corrupt up to 𝑛−1 parties, while the remaining parties are corrupt in a functionality-preserving way.\r\nOur core techniques are: malleable commitments and malleable non-interactive zero-knowledge, which in particular allow us to create a novel protocol for multiparty augmented coin-tossing into the well with reverse firewalls (that is based on a protocol of Lindell from Crypto 2001)."}],"oa_version":"Preprint","volume":12171,"ec_funded":1,"publication_identifier":{"isbn":["9783030568795"],"eissn":["16113349"],"issn":["03029743"]},"publication_status":"published","language":[{"iso":"eng"}]},{"oa_version":"Preprint","abstract":[{"lang":"eng","text":"Discrete Gaussian distributions over lattices are central to lattice-based cryptography, and to the computational and mathematical aspects of lattices more broadly. The literature contains a wealth of useful theorems about the behavior of discrete Gaussians under convolutions and related operations. Yet despite their structural similarities, most of these theorems are formally incomparable, and their proofs tend to be monolithic and written nearly “from scratch,” making them unnecessarily hard to verify, understand, and extend.\r\nIn this work we present a modular framework for analyzing linear operations on discrete Gaussian distributions. The framework abstracts away the particulars of Gaussians, and usually reduces proofs to the choice of appropriate linear transformations and elementary linear algebra. To showcase the approach, we establish several general properties of discrete Gaussians, and show how to obtain all prior convolution theorems (along with some new ones) as straightforward corollaries. As another application, we describe a self-reduction for Learning With Errors (LWE) that uses a fixed number of samples to generate an unlimited number of additional ones (having somewhat larger error). The distinguishing features of our reduction are its simple analysis in our framework, and its exclusive use of discrete Gaussians without any loss in parameters relative to a prior mixed discrete-and-continuous approach.\r\nAs a contribution of independent interest, for subgaussian random matrices we prove a singular value concentration bound with explicitly stated constants, and we give tighter heuristics for specific distributions that are commonly used for generating lattice trapdoors. These bounds yield improvements in the concrete bit-security estimates for trapdoor lattice cryptosystems."}],"month":"05","intvolume":" 12110","alternative_title":["LNCS"],"scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://eprint.iacr.org/2020/337"}],"language":[{"iso":"eng"}],"publication_identifier":{"isbn":["9783030453732"],"eissn":["16113349"],"issn":["03029743"]},"publication_status":"published","volume":12110,"ec_funded":1,"_id":"8339","status":"public","type":"conference","conference":{"start_date":"2020-05-04","end_date":"2020-05-07","location":"Edinburgh, United Kingdom","name":"PKC: Public-Key Cryptography"},"date_updated":"2023-02-23T13:31:06Z","department":[{"_id":"KrPi"}],"quality_controlled":"1","publisher":"Springer Nature","oa":1,"day":"15","publication":"23rd IACR International Conference on the Practice and Theory of Public-Key Cryptography","year":"2020","doi":"10.1007/978-3-030-45374-9_21","date_published":"2020-05-15T00:00:00Z","date_created":"2020-09-06T22:01:13Z","page":"623-651","project":[{"grant_number":"682815","name":"Teaching Old Crypto New Tricks","call_identifier":"H2020","_id":"258AA5B2-B435-11E9-9278-68D0E5697425"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Genise N, Micciancio D, Peikert C, Walter M. 2020.
