In addition to isotropic chemical-shift fluctuations exploited in solution-state NMR relaxation dispersion experiments, MAS NMR has a wider arsenal of observables, allowing to see motions even if the exchanging states do not differ in their chemical shifts.

Recently, this has changed as isotopic fractionation that deviates from classical mass dependence was reported both in vitro and in vivo. In these cases, the isotopic effect correlates with the nuclear magnetic spin. Here, we show nuclear spin effects using stable oxygen isotopes (16O, 17O, and 18O) in two separate setups: an artificial dioxygen production system and biological aquaporin channels in cells. We observe that oxygen dynamics in chiral environments (in particular its transport) depend on nuclear spin, suggesting future applications for controlled isotope separation to be used, for instance, in NMR. To demonstrate the mechanism behind our findings, we formulate theoretical models based on a nuclear-spin-enhanced switch between electronic spin states. Accounting for the role of nuclear spin in biology can provide insights into the role of quantum effects in living systems and help inspire the development of future biotechnology solutions."}],"quality_controlled":"1","publication_identifier":{"eissn":["1091-6490"]},"ec_funded":1,"year":"2023","language":[{"iso":"eng"}],"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","article_type":"original","publisher":"National Academy of Sciences","issue":"32","day":"31","article_processing_charge":"Yes (in subscription journal)","has_accepted_license":"1","department":[{"_id":"MiLe"}],"doi":"10.1073/pnas.2300828120","scopus_import":"1","intvolume":"       120","author":[{"full_name":"Vardi, Ofek","last_name":"Vardi","first_name":"Ofek"},{"last_name":"Maroudas-Sklare","full_name":"Maroudas-Sklare, Naama","first_name":"Naama"},{"first_name":"Yuval","full_name":"Kolodny, Yuval","last_name":"Kolodny"},{"full_name":"Volosniev, Artem","last_name":"Volosniev","orcid":"0000-0003-0393-5525","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","first_name":"Artem"},{"full_name":"Saragovi, Amijai","last_name":"Saragovi","first_name":"Amijai"},{"first_name":"Nir","full_name":"Galili, Nir","last_name":"Galili"},{"first_name":"Stav","last_name":"Ferrera","full_name":"Ferrera, Stav"},{"id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","first_name":"Areg","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg","orcid":"0000-0001-9666-3543"},{"first_name":"Nir","last_name":"Yuran","full_name":"Yuran, Nir"},{"full_name":"Affek, Hagit P.","last_name":"Affek","first_name":"Hagit P."},{"full_name":"Luz, Boaz","last_name":"Luz","first_name":"Boaz"},{"first_name":"Yonaton","last_name":"Goldsmith","full_name":"Goldsmith, Yonaton"},{"last_name":"Keren","full_name":"Keren, Nir","first_name":"Nir"},{"full_name":"Yochelis, Shira","last_name":"Yochelis","first_name":"Shira"},{"first_name":"Itay","last_name":"Halevy","full_name":"Halevy, Itay"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","orcid":"0000-0002-6990-7802"},{"last_name":"Paltiel","full_name":"Paltiel, Yossi","first_name":"Yossi"}],"volume":120,"date_created":"2023-08-13T22:01:12Z","oa":1,"month":"07","_id":"14037","ddc":["530"],"file_date_updated":"2023-08-14T07:43:45Z","status":"public","oa_version":"Published Version","article_number":"e2300828120"},{"department":[{"_id":"MaLo"}],"has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","day":"07","issue":"15","publisher":"Elsevier","article_type":"original","page":"1315-1332","language":[{"iso":"eng"}],"year":"2023","oa_version":"Published Version","status":"public","ddc":["570"],"_id":"14039","file_date_updated":"2023-08-14T07:57:55Z","month":"08","oa":1,"date_created":"2023-08-13T22:01:12Z","volume":58,"author":[{"first_name":"Thomas A.","full_name":"Leonard, Thomas A.","last_name":"Leonard"},{"first_name":"Martin","id":"462D4284-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7309-9724","full_name":"Loose, Martin","last_name":"Loose"},{"full_name":"Martens, Sascha","last_name":"Martens","first_name":"Sascha"}],"intvolume":"        58","scopus_import":"1","doi":"10.1016/j.devcel.2023.06.001","type":"journal_article","acknowledgement":"We acknowledge funding from the Austrian Science Fund (FWF F79, P32814-B, and P35061-B to S.M.; P34607-B to M.L.; and P30584-B and P33066-B to T.A.L.) and the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation program (grant agreement no. 101045340 to M.L.).

The membrane surface is, therefore, an essential platform upon which myriad cellular processes are scaffolded. In this review, we summarize our current understanding of the biophysics and biochemistry of membrane-localized reactions with particular focus on insights derived from reconstituted and cellular systems.

The highly conserved Ycf48 assembly factor binds to the newly synthesized D1 reaction center polypeptide and promotes the initial steps of PSII assembly, but its binding site is unclear. Here we use cryo-electron microscopy to determine the structure of a cyanobacterial PSII D1/D2 reaction center assembly complex with Ycf48 attached. Ycf48, a 7-bladed beta propeller, binds to the amino-acid residues of D1 that ultimately ligate the water-oxidising Mn4CaO5 cluster, thereby preventing the premature binding of Mn2+ and Ca2+ ions and protecting the site from damage. Interactions with D2 help explain how Ycf48 promotes assembly of the D1/D2 complex. Overall, our work provides valuable insights into the early stages of PSII assembly and the structural changes that create the binding site for the Mn4CaO5 cluster."}],"publication_status":"published","title":"The Ycf48 accessory factor occupies the site of the oxygen-evolving manganese cluster during photosystem II biogenesis","date_updated":"2025-04-23T13:05:33Z","isi":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"date_published":"2023-08-04T00:00:00Z","external_id":{"pmid":["37542031"],"isi":["001042606700004"]},"corr_author":"1","publication_identifier":{"eissn":["2041-1723"]},"year":"2023","language":[{"iso":"eng"}],"article_processing_charge":"Yes","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"LifeSc"},{"_id":"ScienComp"}],"has_accepted_license":"1","department":[{"_id":"LeSa"}],"publisher":"Springer Nature","article_type":"original","day":"04","author":[{"last_name":"Zhao","full_name":"Zhao, Ziyu","first_name":"Ziyu"},{"first_name":"Irene","id":"3ED6AF16-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5618-3449","full_name":"Vercellino, Irene","last_name":"Vercellino"},{"first_name":"Jana","last_name":"Knoppová","full_name":"Knoppová, Jana"},{"last_name":"Sobotka","full_name":"Sobotka, Roman","first_name":"Roman"},{"last_name":"Murray","full_name":"Murray, James W.","first_name":"James W."},{"last_name":"Nixon","full_name":"Nixon, Peter J.","first_name":"Peter J."},{"first_name":"Leonid A","id":"338D39FE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0977-7989","last_name":"Sazanov","full_name":"Sazanov, Leonid A"},{"first_name":"Josef","full_name":"Komenda, Josef","last_name":"Komenda"}],"volume":14,"date_created":"2023-08-13T22:01:13Z","doi":"10.1038/s41467-023-40388-6","scopus_import":"1","intvolume":"        14","_id":"14040","file_date_updated":"2023-08-14T07:01:12Z","ddc":["570"],"oa_version":"Published Version","status":"public","article_number":"4681","oa":1,"month":"08"},{"abstract":[{"text":"Tissue morphogenesis and patterning during development involve the segregation of cell types. Segregation is driven by differential tissue surface tensions generated by cell types through controlling cell-cell contact formation by regulating adhesion and actomyosin contractility-based cellular cortical tensions. We use vertebrate tissue cell types and zebrafish germ layer progenitors as in vitro models of 3-dimensional heterotypic segregation and developed a quantitative analysis of their dynamics based on 3D time-lapse microscopy. We show that general inhibition of actomyosin contractility by the Rho kinase inhibitor Y27632 delays segregation. Cell type-specific inhibition of non-muscle myosin2 activity by overexpression of myosin assembly inhibitor S100A4 reduces tissue surface tension, manifested in decreased compaction during aggregation and inverted geometry observed during segregation. The same is observed when we express a constitutively active Rho kinase isoform to ubiquitously keep actomyosin contractility high at cell-cell and cell-medium interfaces and thus overriding the interface-specific regulation of cortical tensions. Tissue surface tension regulation can become an effective tool in tissue engineering.","lang":"eng"}],"quality_controlled":"1","title":"3D cell segregation geometry and dynamics are governed by tissue surface tension regulation","publication_status":"published","date_updated":"2023-12-13T12:07:33Z","external_id":{"isi":["001042544100001"],"pmid":["37542157"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"date_published":"2023-08-04T00:00:00Z","isi":1,"publication_identifier":{"eissn":["2399-3642"]},"publication":"Communications Biology","citation":{"short":"E.

The majority of such studies however concerns models where such a dependence is explicit (the stress is a function of the velocity gradient), which makes the class of studied models unduly restrictive. The same concerns boundary conditions, or more precisely the slipping mechanisms on the boundary, where the no-slip is still the most preferred condition considered in the literature. Our main objective is to develop a robust mathematical theory for unsteady internal flows of implicitly constituted incompressible fluids with implicit relations between the tangential projections of the velocity and the normal traction on the boundary. The theory covers numerous rheological models used in chemistry, biorheology, polymer and food industry as well as in geomechanics. It also includes, as special cases, nonlinear slip as well as stick–slip boundary conditions. Unlike earlier studies, the conditions characterizing admissible classes of constitutive equations are expressed by means of tools of elementary calculus. In addition, a fully constructive proof (approximation scheme) is incorporated. Finally, we focus on the question of uniqueness of such weak solutions."}],"quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["001040354900001"],"arxiv":["2301.12834"]},"date_published":"2023-08-01T00:00:00Z","isi":1,"title":"On unsteady internal flows of incompressible fluids characterized by implicit constitutive equations in the bulk and on the boundary","publication_status":"published","date_updated":"2023-12-13T12:08:08Z"},{"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2010.16316"}],"author":[{"orcid":"0000-0002-5008-6530","full_name":"Henzinger, Monika H","last_name":"Henzinger","first_name":"Monika H","id":"540c9bbd-f2de-11ec-812d-d04a5be85630"},{"first_name":"Billy","full_name":"Jin, Billy","last_name":"Jin"},{"full_name":"Peng, Richard","last_name":"Peng","first_name":"Richard"},{"full_name":"Williamson, David P.","last_name":"Williamson","first_name":"David P."}],"date_created":"2023-08-13T22:01:13Z","volume":85,"scopus_import":"1","doi":"10.1007/s00453-023-01154-8","intvolume":"        85","oa_version":"Preprint","status":"public","_id":"14043","oa":1,"month":"12","page":"2680-3716","language":[{"iso":"eng"}],"year":"2023","article_processing_charge":"No","department":[{"_id":"MoHe"}],"publisher":"Springer Nature","article_type":"original","day":"01","quality_controlled":"1","abstract":[{"lang":"eng","text":"Over the last two decades, a significant line of work in theoretical algorithms has made progress in solving linear systems of the form Lx=b, where L is the Laplacian matrix of a weighted graph with weights w(i,j)>0 on the edges. The solution x of the linear system can be interpreted as the potentials of an electrical flow in which the resistance on edge (i, j) is 1/w(i, j). Kelner et al. (in: Proceedings of the 45th Annual ACM Symposium on the Theory of Computing, pp 911–920, 2013. https://doi.org/10.1145/2488608.2488724) give a combinatorial, near-linear time algorithm that maintains the Kirchoff Current Law, and gradually enforces the Kirchoff Potential Law by updating flows around cycles (cycle toggling). In this paper, we consider a dual version of the algorithm that maintains the Kirchoff Potential Law, and gradually enforces the Kirchoff Current Law by cut toggling: each iteration updates all potentials on one side of a fundamental cut of a spanning tree by the same amount. We prove that this dual algorithm also runs in a near-linear number of iterations. We show, however, that if we abstract cut toggling as a natural data structure problem, this problem can be reduced to the online vector–matrix-vector problem, which has been conjectured to be difficult for dynamic algorithms (Henzinger et al., in: Proceedings of the 47th Annual ACM Symposium on the Theory of Computing, pp 21–30, 2015. https://doi.org/10.1145/2746539.2746609). The conjecture implies that the data structure does not have an O(n1−ϵ) time algorithm for any ϵ>0, and thus a straightforward implementation of the cut-toggling algorithm requires essentially linear time per iteration. To circumvent the lower bound, we batch update steps, and perform them simultaneously instead of sequentially. An appropriate choice of batching leads to an O˜(m1.5) time cut-toggling algorithm for solving Laplacian systems. Furthermore, we show that if we sparsify the graph and call our algorithm recursively on the Laplacian system implied by batching and sparsifying, we can reduce the running time to O(m1+ϵ) for any ϵ>0. Thus, the dual cut-toggling algorithm can achieve (almost) the same running time as its primal cycle-toggling counterpart."}],"date_updated":"2025-04-15T06:24:05Z","project":[{"call_identifier":"H2020","_id":"bd9ca328-d553-11ed-ba76-dc4f890cfe62","name":"The design and evaluation of modern fully dynamic data structures","grant_number":"101019564"},{"grant_number":"P33775","_id":"bd9e3a2e-d553-11ed-ba76-8aa684ce17fe","name":"Fast Algorithms for a Reactive Network Layer"}],"publication_status":"published","title":"A combinatorial cut-toggling algorithm for solving Laplacian linear systems","date_published":"2023-12-01T00:00:00Z","external_id":{"isi":["001041254900002"],"arxiv":["2010.16316"]},"isi":1,"arxiv":1,"ec_funded":1,"publication_identifier":{"issn":["0178-4617"],"eissn":["1432-0541"]},"publication":"Algorithmica","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"M.

Previous work on monitoring hyperproperties focused on synchronous hyperproperties, usually specified in HyperLTL. When monitoring synchronous hyperproperties, all traces are assumed to proceed at the same speed. We introduce (multi-trace) prefix transducers and show how to use them for monitoring synchronous as well as, for the first time, asynchronous hyperproperties. Prefix transducers map multiple input traces into one or more output traces by incrementally matching prefixes of the input traces against expressions similar to regular expressions. The prefixes of different traces which are consumed by a single matching step of the monitor may have different lengths. The deterministic and executable nature of prefix transducers makes them more suitable as an intermediate formalism for runtime verification than logical specifications, which tend to be highly non-deterministic, especially in the case of asynchronous hyperproperties. We report on a set of experiments about monitoring asynchronous version of observational determinism.","lang":"eng"}],"date_updated":"2025-04-14T09:42:55Z","project":[{"grant_number":"101020093","call_identifier":"H2020","name":"Vigilant Algorithmic Monitoring of Software","_id":"62781420-2b32-11ec-9570-8d9b63373d4d"}],"title":"Monitoring hyperproperties with prefix transducers","publication_status":"published","date_published":"2023-10-01T00:00:00Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"ec_funded":1,"publication_identifier":{"isbn":["978-3-031-44266-7"],"eisbn":["978-3-031-44267-4"]},"corr_author":"1","page":"168-190","language":[{"iso":"eng"}],"year":"2023","has_accepted_license":"1","article_processing_charge":"Yes (in subscription journal)","department":[{"_id":"ToHe"}],"publisher":"Springer Nature","day":"01","author":[{"id":"87e34708-d6c6-11ec-9f5b-9391e7be2463","first_name":"Marek","full_name":"Chalupa, Marek","last_name":"Chalupa"},{"first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2985-7724","full_name":"Henzinger, Thomas A","last_name":"Henzinger"}],"date_created":"2023-08-16T20:46:08Z","related_material":{"record":[{"id":"15035","relation":"research_data","status":"public"}]},"volume":14245,"scopus_import":"1","doi":"10.1007/978-3-031-44267-4_9","intvolume":"     14245","oa_version":"Published Version","status":"public","_id":"14076","ddc":["000"],"file_date_updated":"2023-10-16T07:15:11Z","oa":1,"month":"10"},{"issue":"10","day":"01","publisher":"Elsevier","article_type":"review","department":[{"_id":"CaHe"}],"has_accepted_license":"1","article_processing_charge":"Yes (in subscription journal)","language":[{"iso":"eng"}],"year":"2023","month":"10","oa":1,"article_number":"102217","status":"public","oa_version":"Published Version","ddc":["570"],"_id":"14080","file_date_updated":"2024-01-30T12:52:12Z","intvolume":"        84","scopus_import":"1","doi":"10.1016/j.ceb.2023.102217","date_created":"2023-08-20T22:01:12Z","volume":84,"author":[{"last_name":"Hirashima","full_name":"Hirashima, Tsuyoshi","first_name":"Tsuyoshi"},{"id":"5299a9ce-7679-11eb-a7bc-d1e62b936307","first_name":"Naoya","full_name":"Hino, Naoya","last_name":"Hino"},{"first_name":"Kazuhiro","last_name":"Aoki","full_name":"Aoki, Kazuhiro"},{"last_name":"Matsuda","full_name":"Matsuda, Michiyuki","first_name":"Michiyuki"}],"file":[{"date_created":"2024-01-30T12:52:12Z","file_name":"2023_CurrentOpinionCellBio_Hirashima.pdf","success":1,"date_updated":"2024-01-30T12:52:12Z","creator":"dernst","access_level":"open_access","file_size":1173762,"file_id":"14909","content_type":"application/pdf","relation":"main_file","checksum":"25923f8ae71344e8974530dd23c71bdc"}],"type":"journal_article","acknowledgement":"TH was supported by JSPS KAKENHI Grant (no. 21H05290) and the Ministry of Education under the Research Centres of Excellence programme through the Mechanobiology Institute at National University of Singapore and by Department of Physiology at National University of Singapore.

Although these methods measure changes in global barrier function, they lack the sensitivity needed to detect local or transient barrier breaches, and they do not reveal the location of barrier leaks. Therefore, we previously developed a method that we named the zinc-based ultrasensitive microscopic barrier assay (ZnUMBA), which overcomes these limitations, allowing for detection of local tight junction leaks with high spatiotemporal resolution. Here, we present expanded applications for ZnUMBA. ZnUMBA can be used in Xenopus embryos to measure the dynamics of barrier restoration and actin accumulation following laser injury. ZnUMBA can also be effectively utilized in developing zebrafish embryos as well as cultured monolayers of Madin–Darby canine kidney (MDCK) II epithelial cells. ZnUMBA is a powerful and flexible method that, with minimal optimization, can be applied to multiple systems to measure dynamic changes in barrier function with spatiotemporal precision.","lang":"eng"}],"quality_controlled":"1","publication_identifier":{"eissn":["1477-9137"],"issn":["0021-9533"]},"ec_funded":1,"citation":{"short":"T.

A code is called (p,L)_q-list-decodable if every radius pn Hamming ball contains less than L codewords; (p,𝓁,L)_q-list-recoverability is a generalization where we place radius pn Hamming balls on every point of a combinatorial rectangle with side length 𝓁 and again stipulate that there be less than L codewords.\r\nOur main contribution is to precisely calculate the maximum value of p for which there exist infinite families of positive rate (p,𝓁,L)_q-list-recoverable codes, the quantity we call the zero-rate threshold. Denoting this value by p_*, we in fact show that codes correcting a p_*+ε fraction of errors must have size O_ε(1), i.e., independent of n. Such a result is typically referred to as a \"Plotkin bound.\" To complement this, a standard random code with expurgation construction shows that there exist positive rate codes correcting a p_*-ε fraction of errors. We also follow a classical proof template (typically attributed to Elias and Bassalygo) to derive from the zero-rate threshold other tradeoffs between rate and decoding radius for list-decoding and list-recovery.\r\nTechnically, proving the Plotkin bound boils down to demonstrating the Schur convexity of a certain function defined on the q-simplex as well as the convexity of a univariate function derived from it. We remark that an earlier argument claimed similar results for q-ary list-decoding; however, we point out that this earlier proof is flawed.","lang":"eng"}],"corr_author":"1","publication_identifier":{"isbn":["9783959772785"],"issn":["1868-8969"]},"arxiv":1},{"publication":"50th International Colloquium on Automata, Languages, and Programming","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Harris, D.

Though tight approximation algorithms for general matroid constraints exist in theory, the running times of such algorithms typically scale quadratically, and are not practical for truly large scale settings. Recent progress has focused on fast algorithms for important classes of matroids given in explicit form. Currently, nearly-linear time algorithms only exist for graphic and partition matroids [Alina Ene and Huy L. Nguyen, 2019]. In this work, we develop algorithms for monotone submodular maximization constrained by graphic, transversal matroids, or laminar matroids in time near-linear in the size of their representation. Our algorithms achieve an optimal approximation of 1-1/e-ε and both generalize and accelerate the results of Ene and Nguyen [Alina Ene and Huy L. Nguyen, 2019]. In fact, the running time of our algorithm cannot be improved within the fast continuous greedy framework of Badanidiyuru and Vondrák [Ashwinkumar Badanidiyuru and Jan Vondrák, 2014].\r\nTo achieve near-linear running time, we make use of dynamic data structures that maintain bases with approximate maximum cardinality and weight under certain element updates. These data structures need to support a weight decrease operation and a novel Freeze operation that allows the algorithm to freeze elements (i.e. force to be contained) in its basis regardless of future data structure operations. For the laminar matroid, we present a new dynamic data structure using the top tree interface of Alstrup, Holm, de Lichtenberg, and Thorup [Stephen Alstrup et al., 2005] that maintains the maximum weight basis under insertions and deletions of elements in O(log n) time. This data structure needs to support certain subtree query and path update operations that are performed every insertion and deletion that are non-trivial to handle in conjunction. For the transversal matroid the Freeze operation corresponds to requiring the data structure to keep a certain set S of vertices matched, a property that we call S-stability. While there is a large body of work on dynamic matching algorithms, none are S-stable and maintain an approximate maximum weight matching under vertex updates. We give the first such algorithm for bipartite graphs with total running time linear (up to log factors) in the number of edges."}],"quality_controlled":"1","external_id":{"arxiv":["2305.00122"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"date_published":"2023-07-01T00:00:00Z","date_updated":"2025-07-10T11:50:45Z","project":[{"grant_number":"101019564","call_identifier":"H2020","_id":"bd9ca328-d553-11ed-ba76-dc4f890cfe62","name":"The design and evaluation of modern fully dynamic data structures"},{"grant_number":"I05982","name":"Static and Dynamic Hierarchical Graph Decompositions","_id":"bda196b2-d553-11ed-ba76-8e8ee6c21103"},{"grant_number":"P33775","_id":"bd9e3a2e-d553-11ed-ba76-8aa684ce17fe","name":"Fast Algorithms for a Reactive Network Layer"}],"title":"Faster submodular maximization for several classes of matroids","publication_status":"published","conference":{"end_date":"2023-07-14","location":"Paderborn, Germany","start_date":"2023-07-10","name":"ICALP: Automata, Languages and Programming"},"type":"conference","acknowledgement":" Monika Henzinger: This project has received funding from the European Research Council\r\n(ERC) under the European Union’s Horizon 2020 research and innovation programme (Grant\r\nagreement No. 101019564 “The Design of Modern Fully Dynamic Data Structures (MoDynStruct)” and from the Austrian Science Fund (FWF) project “Static and Dynamic Hierarchical Graph Decompositions”, I 5982-N, and project “Fast Algorithms for a Reactive Network Layer (ReactNet)”, P 33775-N, with additional funding from the netidee SCIENCE Stiftung, 2020–2024.

We study theoretically the incompressible flow profiles around ±1 defects induced by polar and dipolar active forces. We show that dipolar forces induce vortical flows around the +1 defect, while the flow around the −1 defect has an 8-fold rotational symmetry. The vortical flow changes its chirality near the +1 defect core in the absence of the friction with a substrate. We show analytically that the flow induced by polar active forces is vortical near the +1 defect and is 4-fold symmetric near the −1 defect, while it becomes uniform in the far-field. For a pair of oppositely charged defects, this polar flow contributes to a mutual interaction force that depends only on the orientation of the defect pair relative to the background polarization, and that enhances defect pair annihilation. This is in contradiction with the effect of dipolar active forces which decay inversely proportional with the defect separation distance. As such, our analyses reveals a long-ranged mechanism for the pairwise interaction between topological defects in polar active matter.","lang":"eng"}],"publication_identifier":{"issn":["1744-683X"],"eissn":["1744-6848"]},"arxiv":1},{"type":"journal_article","citation":{"ieee":"J.

Many transient phenomena will remain enigmatic until we achieve a firm understanding of the physics and evolution of massive stars at low metallicity (Z). The Hubble Space Telescope has devoted 500 orbits to observing ∼250 massive stars at low Z in the ultraviolet (UV) with the COS and STIS spectrographs under the ULLYSES programme. The complementary X-Shooting ULLYSES (XShootU) project provides an enhanced legacy value with high-quality optical and near-infrared spectra obtained with the wide-wavelength coverage X-shooter spectrograph at ESO’s Very Large Telescope. We present an overview of the XShootU project, showing that combining ULLYSES UV and XShootU optical spectra is critical for the uniform determination of stellar parameters such as effective temperature, surface gravity, luminosity, and abundances, as well as wind properties such as mass-loss rates as a function of Z. As uncertainties in stellar and wind parameters percolate into many adjacent areas of astrophysics, the data and modelling of the XShootU project is expected to be a game changer for our physical understanding of massive stars at low Z. To be able to confidently interpret James Webb Space Telescope spectra of the first stellar generations, the individual spectra of low-Z stars need to be understood, which is exactly where XShootU can deliver.","lang":"eng"}],"quality_controlled":"1","article_type":"original","publisher":"EDP Sciences","day":"01","article_processing_charge":"No","year":"2023","language":[{"iso":"eng"}],"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"oa":1,"month":"07","_id":"14103","status":"public","oa_version":"Published Version","article_number":"A154","extern":"1","doi":"10.1051/0004-6361/202245650","scopus_import":"1","intvolume":"       675","author":[{"first_name":"Jorick S.","full_name":"Vink, Jorick S.","last_name":"Vink"},{"full_name":"Mehner, A.","last_name":"Mehner","first_name":"A."},{"last_name":"Crowther","full_name":"Crowther, P.

In this work, we have computed the first grid of evolutionary models of TŻOs with the MESA stellar evolution code. With these models, we predict several observational properties of TŻOs, including their surface temperatures and luminosities, pulsation periods, and nucleosynthetic products. We expand the range of possible TŻO solutions to cover 3.45≲log(Teff/K)≲3.65 and 4.85≲log(L/L⊙)≲5.5⁠. Due to the much higher densities our TŻOs reach compared to previous models, if TŻOs form we expect them to be stable over a larger mass range than previously predicted, without exhibiting a gap in their mass distribution. Using the GYRE stellar pulsation code we show that TŻOs should have fundamental pulsation periods of 1000–2000 d, and period ratios of ≈0.2–0.3. Models computed with a large 399 isotope fully coupled nuclear network show a nucleosynthetic signal that is different to previously predicted. We propose a new nucleosynthetic signal to determine a star’s status as a TŻO: the isotopologues 44TiO2 and 44TiO⁠, which will have a shift in their spectral features as compared to stable titanium-containing molecules. We find that in the local Universe (∼SMC metallicities and above) TŻOs show little heavy metal enrichment, potentially explaining the difficulty in finding TŻOs to-date."}],"publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"arxiv":1,"citation":{"short":"R.

Many recently proposed approaches try to counter this by aligning the model to the new distribution prior to inference. With no labels available this requires unsupervised objectives to adapt the model on the observed test data. In this paper, we propose Test-Time SelfTraining (TeST): a technique that takes as input a model trained on some source data and a novel data distribution at test time, and learns invariant and robust representations using a student-teacher framework. We find that models adapted using TeST significantly improve over baseline testtime adaptation algorithms. TeST achieves competitive performance to modern domain adaptation algorithms [4, 43], while having access to 5-10x less data at time of adaption. We thoroughly evaluate a variety of baselines on two tasks:\r\nobject detection and image segmentation and find that models adapted with TeST. We find that TeST sets the new stateof-the art for test-time domain adaptation algorithms.

Most machine learning efforts addressing this issue in an unsupervised setting have focused on slot-based methods, which may be limiting due to their discrete nature and difficulty to express uncertainty. Recently, the Complex AutoEncoder was proposed as an alternative that learns continuous and distributed object-centric representations. However, it is only applicable to simple toy data. In this paper, we present Rotating Features, a generalization of complex-valued features to higher dimensions, and a new evaluation procedure for extracting objects from distributed representations. Additionally, we show the applicability of our approach to pre-trained features. Together, these advancements enable us to scale distributed object-centric representations from simple toy to real-world data. We believe this work advances a new paradigm for addressing the binding problem in machine learning and has the potential to inspire further innovation in the field."}],"main_file_link":[{"url":"https://arxiv.org/abs/2306.00600","open_access":"1"}],"author":[{"first_name":"Sindy","last_name":"Löwe","full_name":"Löwe, Sindy"},{"last_name":"Lippe","full_name":"Lippe, Phillip","first_name":"Phillip"},{"id":"26cfd52f-2483-11ee-8040-88983bcc06d4","first_name":"Francesco","last_name":"Locatello","full_name":"Locatello, Francesco","orcid":"0000-0002-4850-0683"},{"first_name":"Max","last_name":"Welling","full_name":"Welling, Max"}],"date_created":"2023-08-22T14:18:00Z","day":"01","type":"preprint","article_processing_charge":"No","department":[{"_id":"FrLo"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Löwe, Sindy, et al. “Rotating Features for Object Discovery.” <i>ArXiv</i>, 2306.00600, doi:<a href=\"https://doi.org/10.48550/arXiv.2306.00600\">10.48550/arXiv.2306.00600</a>.","ista":"Löwe S, Lippe P, Locatello F, Welling M.
