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."}],"date_created":"2021-11-26T08:21:34Z","publication":"Science","type":"journal_article","intvolume":"       369","citation":{"short":"G.

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."}],"day":"08","date_created":"2021-11-26T09:08:19Z","keyword":["general chemistry"],"volume":11,"license":"https://creativecommons.org/licenses/by-nc/3.0/","title":"Identification of on- and off-pathway oligomers in amyloid fibril formation","main_file_link":[{"url":"https://pubs.rsc.org/en/content/articlehtml/2020/sc/c9sc06501f","open_access":"1"}],"language":[{"iso":"eng"}]},{"quality_controlled":"1","author":[{"last_name":"Michaels","first_name":"Thomas C.

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.

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."}],"day":"28","type":"journal_article","publication":"Physical Review E","intvolume":"       101","external_id":{"pmid":["32168597"]},"acknowledgement":"We thank Dino Osmanović (MIT), Roy Beck (Tel-Aviv), Larissa Kapinos (Basel), Roderick Lim (Basel), Ralf Richter (Leeds), and Anton Zilman (Toronto) for discussions.

As a result, using our ADKG we remove the trusted setup assumption that the most scalable consensus algorithms make. In order to create a DKG with a dual (f,2f+1)- threshold we first answer in the affirmative the open question posed by Cachin et al. [7] on how to create an Asynchronous Verifiable Secret Sharing (AVSS) protocol with a reconstruction threshold of f+1<k łe 2f+1, which is of independent interest. Our High-threshold-AVSS (HAVSS) uses an asymmetric bivariate polynomial to encode the secret. This enables the reconstruction of the secret only if a set of k nodes contribute while allowing an honest node that did not participate in the sharing phase to recover his share with the help of f+1 honest parties. Once we have HAVSS we can use it to bootstrap scalable partially synchronous consensus protocols, but the question on how to get a DKG in asynchrony remains as we need a way to produce common randomness. The solution comes from a novel Eventually Perfect Common Coin (EPCC) abstraction that enables the generation of a common coin from n concurrent HAVSS invocations. EPCC's key property is that it is eventually reliable, as it might fail to agree at most f times (even if invoked a polynomial number of times). Using EPCC we implement an Eventually Efficient Asynchronous Binary Agreement (EEABA) which is optimal when the EPCC agrees and protects safety when EPCC fails. Finally, using EEABA we construct the first ADKG which has the same overhead and expected runtime as the best partially-synchronous DKG (O(n4) words, O(f) rounds). As a corollary of our ADKG, we can also create the first Validated Asynchronous Byzantine Agreement (VABA) that does not need a trusted dealer to setup threshold signatures of degree n-f. Our VABA has an overhead of expected O(n2) words and O(1) time per instance, after an initial O(n4) words and O(f) time bootstrap via ADKG."}],"day":"30","date_created":"2021-12-16T13:23:27Z","title":"Asynchronous distributed key generation for computationally-secure randomness, consensus, and threshold signatures","main_file_link":[{"url":"https://eprint.iacr.org/2019/1015","open_access":"1"}],"language":[{"iso":"eng"}],"isi":1,"scopus_import":"1","year":"2020","status":"public","oa_version":"Preprint","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"isbn":["978-1-4503-7089-9"]},"conference":{"start_date":"2020-11-09","name":"CCS: Conference on Computer and Communications Security","end_date":"2020-11-13","location":"Virtual, United States"},"department":[{"_id":"ElKo"}],"article_processing_charge":"No","oa":1,"publisher":"Association for Computing Machinery","date_published":"2020-10-30T00:00:00Z","month":"10","date_updated":"2025-07-10T11:49:52Z","publication_status":"published"},{"publication_date":"2020-03-03","type":"patent","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","ipc":" H04L9/3247 ; G06Q20/29 ; G06Q20/382 ; H04L9/3236","citation":{"ama":"Ford B, Gasse L, Kokoris Kogias E, Jovanovic P.

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."}],"day":"23","keyword":["multidisciplinary"],"volume":588,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2004.11353"}],"language":[{"iso":"eng"}],"title":"Electrical switching of magnetic order in an orbital Chern insulator","intvolume":"       588","arxiv":1,"external_id":{"pmid":["33230333"],"arxiv":["2004.11353"]},"citation":{"ieee":"H.

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. Our hope, is that the topics we have presented will provide inspiration for others working in this field and motivation for the idea that significant progress can be made on very hard problems if we focus our collective energies.","lang":"eng"}],"date_created":"2022-01-20T10:55:36Z","title":"The future of the correlated electron problem","language":[{"iso":"eng"}],"oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2010.00584"}],"date_published":"2020-10-01T00:00:00Z","month":"10","date_updated":"2022-01-24T08:05:51Z","publication_status":"submitted","extern":"1"},{"year":"2020","status":"public","corr_author":"1","has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","file":[{"file_id":"10677","file_name":"iclr_2020.pdf","date_created":"2022-01-26T07:35:17Z","relation":"main_file","date_updated":"2022-01-26T07:35:17Z","creator":"mlechner","checksum":"ea13d42dd4541ddb239b6a75821fd6c9","file_size":249431,"access_level":"open_access","content_type":"application/pdf","success":1}],"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0)","image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (3.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/3.0/legalcode"},"oa":1,"article_processing_charge":"No","conference":{"end_date":"2020-05-01","location":"Virtual ; Addis Ababa, Ethiopia","start_date":"2020-04-26","name":"ICLR: International Conference on Learning Representations"},"department":[{"_id":"GradSch"},{"_id":"ToHe"}],"date_updated":"2025-04-15T06:25:56Z","publication_status":"published","month":"03","date_published":"2020-03-11T00:00:00Z","publisher":"ICLR","quality_controlled":"1","author":[{"last_name":"Lechner","id":"3DC22916-F248-11E8-B48F-1D18A9856A87","first_name":"Mathias","full_name":"Lechner, Mathias"}],"_id":"10672","project":[{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"Formal methods for the design and analysis of complex systems","grant_number":"Z211","call_identifier":"FWF"}],"publication":"8th International Conference on Learning Representations","type":"conference","ddc":["000"],"citation":{"apa":"Lechner, M.

While FA algorithms have been shown to work well in practice, there is a lack of rigorous theory proofing their learning capabilities. Here we introduce the first feedback alignment algorithm with provable learning guarantees. In contrast to existing work, we do not require any assumption about the size or depth of the network except that it has a single output neuron, i.e., such as for binary classification tasks. We show that our FA algorithm can deliver its theoretical promises in practice, surpassing the learning performance of existing FA methods and matching backpropagation in binary classification tasks. Finally, we demonstrate the limits of our FA variant when the number of output neurons grows beyond a certain quantity."}],"scopus_import":"1"},{"oa_version":"Published Version","file":[{"relation":"main_file","date_created":"2022-01-26T11:08:51Z","file_name":"2020_PMLR_Hasani.pdf","file_id":"10691","success":1,"access_level":"open_access","file_size":2329798,"checksum":"c9a4a29161777fc1a89ef451c040e3b1","content_type":"application/pdf","creator":"cchlebak","date_updated":"2022-01-26T11:08:51Z"}],"alternative_title":["PMLR"],"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0)","image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (3.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/3.0/legalcode"},"publication_identifier":{"issn":["2640-3498"]},"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","has_accepted_license":"1","status":"public","year":"2020","date_updated":"2025-04-15T06:25:56Z","publication_status":"published","date_published":"2020-01-01T00:00:00Z","article_processing_charge":"No","department":[{"_id":"GradSch"},{"_id":"ToHe"}],"conference":{"location":"Virtual","end_date":"2020-07-18","name":"ML: Machine Learning","start_date":"2020-07-12"},"oa":1,"ddc":["000"],"citation":{"apa":"Hasani, R., Lechner, M., Amini, A., Rus, D., &#38; Grosu, R.

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.","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"url":"http://proceedings.mlr.press/v119/hasani20a.html","open_access":"1"}],"series_title":"PMLR","title":"A natural lottery ticket winner: Reinforcement learning with ordinary neural circuits","file_date_updated":"2022-01-26T11:08:51Z"},{"publication":"APS March Meeting 2020","type":"conference","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.” <i>APS March Meeting 2020</i>, vol. 65, no. 1, B54. 00007, American Physical Society, 2020.","ieee":"H.

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."}],"day":"01","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","publication_identifier":{"issn":["0003-0503"]},"oa_version":"Published Version","alternative_title":["Bulletin of the American Physical Society"],"status":"public","issue":"1","year":"2020","publication_status":"published","date_updated":"2022-01-27T10:58:38Z","month":"03","date_published":"2020-03-01T00:00:00Z","publisher":"American Physical Society","oa":1,"conference":{"start_date":"2020-03-02","name":"APS: American Physical Society","end_date":"2020-03-06","location":"Denver, CO, United States"},"article_number":"B54. 00007","article_processing_charge":"No"},{"status":"public","issue":"1","year":"2020","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","publication_identifier":{"issn":["0003-0503"]},"alternative_title":["Bulletin of the American Physical Society"],"oa_version":"Published Version","oa":1,"article_number":"B51.00005","conference":{"location":"Denver, CO, United States","end_date":"2020-03-06","name":"APS: American Physical Society","start_date":"2020-03-02"},"article_processing_charge":"No","month":"03","date_published":"2020-03-01T00:00:00Z","date_updated":"2022-02-08T10:22:08Z","publication_status":"published","publisher":"American Physical Society","author":[{"id":"edfc7cb1-526e-11ec-b05a-e6ecc27e4e48","full_name":"Polshyn, Hryhoriy","first_name":"Hryhoriy","last_name":"Polshyn","orcid":"0000-0001-8223-8896"},{"full_name":"Zhu, Jihang","first_name":"Jihang","last_name":"Zhu"},{"last_name":"Kumar","first_name":"Manish","full_name":"Kumar, Manish"},{"first_name":"Takashi","full_name":"Taniguchi, Takashi","last_name":"Taniguchi"},{"full_name":"Watanabe, Kenji","first_name":"Kenji","last_name":"Watanabe"},{"last_name":"MacDonald","full_name":"MacDonald, Allan","first_name":"Allan"},{"last_name":"Young","first_name":"Andrea","full_name":"Young, Andrea"}],"quality_controlled":"1","_id":"10696","type":"conference","publication":"APS March Meeting 2020","intvolume":"        65","citation":{"apa":"Polshyn, H., Zhu, J., Kumar, M., Taniguchi, T., Watanabe, K., MacDonald, A., &#38; Young, A.

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."}],"date_created":"2022-01-28T12:04:09Z","volume":16,"title":"Skyrmion solids in monolayer graphene","main_file_link":[{"url":"https://arxiv.org/abs/1904.11485","open_access":"1"}],"language":[{"iso":"eng"}],"extern":"1","doi":"10.1038/s41567-019-0729-8","_id":"10701","author":[{"last_name":"Zhou","full_name":"Zhou, Haoxin","first_name":"Haoxin"},{"orcid":"0000-0001-8223-8896","last_name":"Polshyn","first_name":"Hryhoriy","full_name":"Polshyn, Hryhoriy","id":"edfc7cb1-526e-11ec-b05a-e6ecc27e4e48"},{"last_name":"Taniguchi","first_name":"Takashi","full_name":"Taniguchi, Takashi"},{"last_name":"Watanabe","full_name":"Watanabe, Kenji","first_name":"Kenji"},{"full_name":"Young, Andrea F.","first_name":"Andrea F.","last_name":"Young"}],"page":"154-158","quality_controlled":"1","arxiv":1,"intvolume":"        16","acknowledgement":"We acknowledge discussions with B.

In particular, variable accretion rates, instabilities, and reverberation effects in the accretion disc of a supermassive black hole are expected to produce correlated flux variations in ultraviolet (UV) and optical bands. Recent work has further argued that binary quasars should exhibit strongly correlated UV and optical periodicities. Strong UV–optical correlations have indeed been established in small samples of (N ≲ 30) quasars with well-sampled light curves, and have extended the ‘bluer-when-brighter’ trend previously found within the optical bands. Here, we further test the nature of quasar variability by examining the observed-frame UV–optical correlations among bright quasars extracted from the Half Million Quasars (HMQ) catalogue. We identified a large sample of 1315 quasars in HMQ with overlapping UV and optical light curves from the Galaxy Evolution Explorer and the Catalina Real-time Transient Survey, respectively. We find that strong correlations exist in this much larger sample, but we rule out, at ∼95 per cent confidence, the simple hypothesis that the intrinsic UV and optical variations of all quasars are fully correlated. Our results therefore imply the existence of physical mechanism(s) that can generate uncorrelated optical and UV flux variations."}],"extern":"1","scopus_import":"1"},{"article_type":"original","date_published":"2020-05-29T00:00:00Z","month":"05","date_updated":"2024-09-11T09:03:15Z","publication_status":"published","publisher":"American Astronomical Society","oa":1,"article_number":"284","article_processing_charge":"No","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publication_identifier":{"issn":["0004-6256","1538-3881"]},"oa_version":"Published Version","year":"2020","status":"public","issue":"6","extern":"1","scopus_import":"1","volume":159,"title":"Optimizing simulation parameters for weak lensing analyses involving non-Gaussian observables","main_file_link":[{"url":"https://doi.org/10.3847/1538-3881/ab8f8c","open_access":"1"}],"language":[{"iso":"eng"}],"abstract":[{"text":"We performed a series of numerical experiments to quantify the sensitivity of the predictions for weak lensing statistics obtained in ray-tracing dark matter (DM)-only simulations, to two hyper-parameters that influence the accuracy as well as the computational cost of the predictions: the thickness of the lens planes used to build past light cones and the mass resolution of the underlying DM simulation. The statistics considered are the power spectrum (PS) and a series of non-Gaussian observables, including the one-point probability density function, lensing peaks, and Minkowski functionals. Counterintuitively, we find that using thin lens planes (< 60 h−1 Mpc on a 240 h−1 Mpc simulation box) suppresses the PS over a broad range of scales beyond what would be acceptable for a survey comparable to the Large Synoptic Survey Telescope (LSST). A mass resolution of 7.2 × 1011 h−1 M⊙ per DM particle (or 2563 particles in a (240 h−1 Mpc)3 box) is sufficient to extract information using the PS and non-Gaussian statistics from weak lensing data at angular scales down to 1' with LSST-like levels of shape noise.","lang":"eng"}],"day":"29","date_created":"2024-09-05T09:35:49Z","type":"journal_article","publication":"The Astronomical Journal","intvolume":"       159","citation":{"ista":"Matilla JMZ, Waterval S, Haiman Z. 2020.
