Different parts of their ZW sex chromosomes have stopped recombining in distinct lineages, creating “evolutionary strata” of various ages. Although the Z-chromosome is well characterized at the genomic and molecular level, the W-chromosome has remained largely unstudied from an evolutionary perspective, as only a few W-linked genes have been detected outside of the model species Schistosoma mansoni. Here, we characterize the gene content and evolution of the W-chromosomes of S. mansoni and of the divergent species S. japonicum. We use a combined RNA/DNA k-mer based pipeline to assemble around 100 candidate W-specific transcripts in each of the species. About half of them map to known protein coding genes, the majority homologous to S. mansoni Z-linked genes. We perform an extended analysis of the evolutionary strata present in the two species (including characterizing a previously undetected young stratum in S. japonicum) to infer patterns of sequence and expression evolution of W-linked genes at different time points after recombination was lost. W-linked genes show evidence of degeneration, including high rates of protein evolution and reduced expression. Most are found in young lineage-specific strata, with only a few high expression ancestral W-genes remaining, consistent with the progressive erosion of nonrecombining regions. Among these, the splicing factor u2af2 stands out as a promising candidate for primary sex determination, opening new avenues for understanding the molecular basis of the reproductive biology of this group."}],"keyword":["sex chromosomes","evolutionary strata","W-linked gene","sex determining gene","schistosome parasites"],"author":[{"first_name":"Marwan N","id":"0B46FACA-A8E1-11E9-9BD3-79D1E5697425","orcid":"0000-0002-5328-7231","full_name":"Elkrewi, Marwan N","last_name":"Elkrewi"},{"orcid":"0000-0002-8876-6494","last_name":"Moldovan","full_name":"Moldovan, Mikhail A.","id":"c8bb7f32-3315-11ec-b58b-e5950e6c14a0","first_name":"Mikhail A."},{"last_name":"Picard","full_name":"Picard, Marion A L","orcid":"0000-0002-8101-2518","first_name":"Marion A L","id":"2C921A7A-F248-11E8-B48F-1D18A9856A87"},{"id":"49E1C5C6-F248-11E8-B48F-1D18A9856A87","first_name":"Beatriz","full_name":"Vicoso, Beatriz","last_name":"Vicoso","orcid":"0000-0002-4579-8306"}],"status":"public"},{"language":[{"iso":"eng"}],"user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","date_updated":"2021-10-28T15:44:05Z","acknowledgement":"The authors warmly thank Mitia Duerinckx for discussions on annealed estimates, and Mathias Schäffner for pointing out that the conditions of [14] apply to  ̄a in the setting of Theorem 2.2 and for discussions on regularity theory for operators with non-standard growth conditions.

To better understand the mechanisms for such sharp compartmentalization, we study the effect of an imposed heterotypic tension at the interface between two distinct cell types in a fully 3D Voronoi model for confluent tissues. We find that cells rapidly sort and self-organize to generate a tissue-scale interface between cell types, and cells adjacent to this interface exhibit signature geometric features including nematic-like ordering, bimodal facet areas, and registration, or alignment, of cell centers on either side of the two-tissue interface. The magnitude of these features scales directly with the magnitude of the imposed tension, suggesting that biologists can estimate the magnitude of tissue surface tension between two tissue types simply by segmenting a 3D tissue. To uncover the underlying physical mechanisms driving these geometric features, we develop two minimal, ordered models using two different underlying lattices that identify an energetic competition between bulk cell shapes and tissue interface area. When the interface area dominates, changes to neighbor topology are costly and occur less frequently, which generates the observed geometric features.","lang":"eng"}]},{"publisher":"Journal of Machine Learning Research","file":[{"date_updated":"2021-10-27T15:34:18Z","access_level":"open_access","content_type":"application/pdf","date_created":"2021-10-27T15:34:18Z","success":1,"file_size":3527521,"checksum":"3389d9d01fc58f8fb4c1a53e14a8abbf","file_name":"2021_JMachLearnRes_Hoefler.pdf","relation":"main_file","file_id":"10192","creator":"cziletti"}],"oa_version":"Published Version","ddc":["000"],"type":"journal_article","issue":"241","_id":"10180","external_id":{"arxiv":["2102.00554"]},"publication_status":"published","publication_identifier":{"eissn":["1533-7928"],"issn":["1532-4435"]},"year":"2021","month":"09","department":[{"_id":"DaAl"}],"article_type":"original","date_updated":"2022-05-13T09:36:08Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"abstract":[{"text":"The growing energy and performance costs of deep learning have driven the community to reduce the size of neural networks by selectively pruning components. Similarly to their biological counterparts, sparse networks generalize just as well, sometimes even better than, the original dense networks. Sparsity promises to reduce the memory footprint of regular networks to fit mobile devices, as well as shorten training time for ever growing networks. In this paper, we survey prior work on sparsity in deep learning and provide an extensive tutorial of sparsification for both inference and training. We describe approaches to remove and add elements of neural networks, different training strategies to achieve model sparsity, and mechanisms to exploit sparsity in practice. Our work distills ideas from more than 300 research papers and provides guidance to practitioners who wish to utilize sparsity today, as well as to researchers whose goal is to push the frontier forward. We include the necessary background on mathematical methods in sparsification, describe phenomena such as early structure adaptation, the intricate relations between sparsity and the training process, and show techniques for achieving acceleration on real hardware. We also define a metric of pruned parameter efficiency that could serve as a baseline for comparison of different sparse networks. We close by speculating on how sparsity can improve future workloads and outline major open problems in the field.","lang":"eng"}],"main_file_link":[{"url":"https://www.jmlr.org/papers/v22/21-0366.html","open_access":"1"}],"scopus_import":"1","author":[{"first_name":"Torsten","last_name":"Hoefler","full_name":"Hoefler, Torsten"},{"id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","first_name":"Dan-Adrian","orcid":"0000-0003-3650-940X","last_name":"Alistarh","full_name":"Alistarh, Dan-Adrian"},{"full_name":"Ben-Nun, Tal","last_name":"Ben-Nun","first_name":"Tal"},{"first_name":"Nikoli","full_name":"Dryden, Nikoli","last_name":"Dryden"},{"last_name":"Peste","full_name":"Peste, Elena-Alexandra","id":"32D78294-F248-11E8-B48F-1D18A9856A87","first_name":"Elena-Alexandra"}],"status":"public","oa":1,"citation":{"apa":"Hoefler, T., Alistarh, D.-A., Ben-Nun, T., Dryden, N., &#38; Peste, E.-A.

For an execution of n events over k threads and d variables, we establish novel bounds that scale as nk+1 for TSO and as nk+1· min(nk2, 2k· d) for PSO. Moreover, based on our solution to these problems, we develop an SMC algorithm under TSO and PSO that uses the RF equivalence. The algorithm is exploration-optimal, in the sense that it is guaranteed to explore each class of the RF partitioning exactly once, and spends polynomial time per class when k is bounded. Finally, we implement all our algorithms in the SMC tool Nidhugg, and perform a large number of experiments over benchmarks from existing literature. Our experimental results show that our algorithms for VTSO-rf and VPSO-rf provide significant scalability improvements over standard alternatives. Moreover, when used for SMC, the RF partitioning is often much coarser than the standard Shasha-Snir partitioning for TSO/PSO, which yields a significant speedup in the model checking task.\r\n\r\n"}],"related_material":{"record":[{"id":"10199","relation":"dissertation_contains","status":"public"}]},"keyword":["safety","risk","reliability and quality","software"],"language":[{"iso":"eng"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2025-07-14T09:10:16Z","author":[{"first_name":"Truc Lam","full_name":"Bui, Truc Lam","last_name":"Bui"},{"first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","orcid":"0000-0002-4561-241X"},{"first_name":"Tushar","last_name":"Gautam","full_name":"Gautam, Tushar"},{"orcid":"0000-0002-8943-0722","full_name":"Pavlogiannis, Andreas","last_name":"Pavlogiannis","first_name":"Andreas","id":"49704004-F248-11E8-B48F-1D18A9856A87"},{"id":"3AF3DA7C-F248-11E8-B48F-1D18A9856A87","first_name":"Viktor","orcid":"0000-0001-9036-063X","last_name":"Toman","full_name":"Toman, Viktor"}],"status":"public","quality_controlled":"1","arxiv":1,"date_created":"2021-10-27T15:05:34Z","citation":{"apa":"Bui, T.

In particular, concurrent programs are notoriously difficult both to be written correctly and to be analyzed formally, as complex thread interaction has to be accounted for. The difficulties are further exacerbated when concurrent programs get executed on modern-day hardware, which contains various buffering and caching mechanisms for efficiency reasons. This causes further subtle non-determinism, which can often produce very unintuitive behavior of the concurrent programs. Model checking is at the forefront of tackling the verification problem, where the task is to decide, given as input a concurrent system and a desired property, whether the system satisfies the property. The inherent state-space explosion problem in model checking of concurrent systems causes naïve explicit methods not to scale, thus more inventive methods are required. One such method is stateless model checking (SMC), which explores in memory-efficient manner the program executions rather than the states of the program. State-of-the-art SMC is typically coupled with partial order reduction (POR) techniques, which argue that certain executions provably produce identical system behavior, thus limiting the amount of executions one needs to explore in order to cover all possible behaviors. Another method to tackle the state-space explosion is symbolic model checking, where the considered techniques operate on a succinct implicit representation of the input system rather than explicitly accessing the system. In this thesis we present new techniques for verification of concurrent systems. We present several novel POR methods for SMC of concurrent programs under various models of semantics, some of which account for write-buffering mechanisms. Additionally, we present novel algorithms for symbolic model checking of finite-state concurrent systems, where the desired property of the systems is to ensure a formally defined notion of fairness.","lang":"eng"}],"status":"public","author":[{"id":"3AF3DA7C-F248-11E8-B48F-1D18A9856A87","first_name":"Viktor","last_name":"Toman","full_name":"Toman, Viktor","orcid":"0000-0001-9036-063X"}],"publisher":"Institute of Science and Technology Austria","supervisor":[{"orcid":"0000-0002-4561-241X","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"}],"oa_version":"Published Version","file":[{"file_name":"toman_th_final.pdf","relation":"main_file","creator":"vtoman","file_id":"10225","date_updated":"2021-11-08T14:12:22Z","content_type":"application/pdf","access_level":"open_access","date_created":"2021-11-08T14:12:22Z","file_size":2915234,"checksum":"4f412a1ee60952221b499a4b1268df35"},{"content_type":"application/zip","access_level":"closed","date_updated":"2021-11-09T09:00:50Z","checksum":"9584943f99127be2dd2963f6784c37d4","file_size":8616056,"date_created":"2021-11-08T14:12:46Z","file_name":"toman_thesis.zip","creator":"vtoman","file_id":"10226","relation":"source_file"}],"type":"dissertation","ddc":["000"],"alternative_title":["ISTA Thesis"],"publication_status":"published","_id":"10199","publication_identifier":{"issn":["2663-337X"]},"project":[{"grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program","call_identifier":"H2020"},{"name":"Rigorous Systems Engineering","call_identifier":"FWF","_id":"25F2ACDE-B435-11E9-9278-68D0E5697425","grant_number":"S11402-N23"},{"grant_number":"ICT15-003","_id":"25892FC0-B435-11E9-9278-68D0E5697425","name":"Efficient Algorithms for Computer Aided Verification"},{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818"}],"month":"10","year":"2021","department":[{"_id":"GradSch"},{"_id":"KrCh"}]},{"title":"Satb2 acts as a gatekeeper for major developmental transitions during early vertebrate embryogenesis","date_created":"2021-10-31T23:01:29Z","citation":{"ama":"Pradhan SJ, Reddy PC, Smutny M, et al.

ZGA is dependent upon dynamic chromatin architecture sculpted by conserved DNA-binding proteins. However, the direct mechanistic link between the onset of ZGA and the tissue-specific transcription remains unclear. Here, we have addressed the involvement of chromatin organizer Satb2 in orchestrating both processes during zebrafish embryogenesis. Integrative analysis of transcriptome, genome-wide occupancy and chromatin accessibility reveals contrasting molecular activities of maternally deposited and zygotically synthesized Satb2. Maternal Satb2 prevents premature transcription of zygotic genes by influencing the interplay between the pluripotency factors. By contrast, zygotic Satb2 activates transcription of the same group of genes during neural crest development and organogenesis. Thus, our comparative analysis of maternal versus zygotic function of Satb2 underscores how these antithetical activities are temporally coordinated and functionally implemented highlighting the evolutionary implications of the biphasic and bimodal regulation of landmark developmental transitions by a single determinant."}],"scopus_import":"1","date_updated":"2023-08-14T10:32:48Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}]},{"publication_identifier":{"eissn":["2041-1723"]},"isi":1,"month":"10","year":"2021","department":[{"_id":"BjHo"}],"article_type":"original","publisher":"Springer Nature","oa_version":"Published Version","type":"journal_article","file":[{"file_id":"10212","creator":"cchlebak","relation":"main_file","file_name":"2021_NatComm_Sortino.pdf","success":1,"file_size":1434201,"checksum":"8580d128389860f732028c521cd5949e","date_created":"2021-11-03T11:31:24Z","access_level":"open_access","content_type":"application/pdf","date_updated":"2021-11-03T11:31:24Z"}],"ddc":["530"],"publication_status":"published","external_id":{"arxiv":["2103.16986"],"isi":["000708601800015"]},"_id":"10203","status":"public","author":[{"full_name":"Sortino, Luca","last_name":"Sortino","first_name":"Luca"},{"last_name":"Zotev","full_name":"Zotev, Panaiot G.","first_name":"Panaiot G."},{"first_name":"Catherine L.","full_name":"Phillips, Catherine L.","last_name":"Phillips"},{"first_name":"Alistair J.","last_name":"Brash","full_name":"Brash, Alistair J."},{"last_name":"Cambiasso","full_name":"Cambiasso, Javier","first_name":"Javier"},{"first_name":"Elena","id":"0BE7553A-1004-11EA-B805-18983DDC885E","last_name":"Marensi","full_name":"Marensi, Elena","orcid":"0000-0001-7173-4923"},{"full_name":"Fox, A.

Here, we couple monolayer WSe2 to high-refractive-index gallium phosphide dielectric nano-antennas providing both optical enhancement and monolayer deformation. For single photon emitters formed on such nano-antennas, we find very low (femto-Joule) saturation pulse energies and up to 104 times brighter photoluminescence than in WSe2 placed on low-refractive-index SiO2 pillars. We show that the key to these observations is the increase on average by a factor of 5 of the quantum efficiency of the emitters coupled to the nano-antennas. This further allows us to gain new insights into their photoluminescence dynamics, revealing the roles of the dark exciton reservoir and Auger processes. We also find that the coherence time of such emitters is limited by intrinsic dephasing processes.

Maintaining this accuracy in dynamic environments, where inputs frequently fall outside the fixed set of initially known classes, remains a challenge. The typical approach is to detect inputs from novel classes and retrain the classifier on an augmented dataset. However, not only the classifier but also the detection mechanism needs to adapt in order to distinguish between newly learned and yet unknown input classes. To address this challenge, we introduce an algorithmic framework for active monitoring of a neural network. A monitor wrapped in our framework operates in parallel with the neural network and interacts with a human user via a series of interpretable labeling queries for incremental adaptation.

Two popular solutions are based on a linear estimator 𝑥𝑥^L and a spectral estimator 𝑥𝑥^s. The former is a data-dependent linear combination of the columns of the measurement matrix, and its analysis is quite simple. The latter is the principal eigenvector of a data-dependent matrix, and a recent line of work has studied its performance. In this paper, we show how to optimally combine 𝑥𝑥^L and 𝑥𝑥^s. At the heart of our analysis is the exact characterization of the empirical joint distribution of (𝑥𝑥,𝑥𝑥^L,𝑥𝑥^s) in the high-dimensional limit. This allows us to compute the Bayes-optimal combination of 𝑥𝑥^L and 𝑥𝑥^s, given the limiting distribution of the signal 𝑥𝑥. When the distribution of the signal is Gaussian, then the Bayes-optimal combination has the form 𝜃𝑥𝑥^L+𝑥𝑥^s and we derive the optimal combination coefficient. In order to establish the limiting distribution of (𝑥𝑥,𝑥𝑥^L,𝑥𝑥^s), we design and analyze an approximate message passing algorithm whose iterates give 𝑥𝑥^L and approach 𝑥𝑥^s. Numerical simulations demonstrate the improvement of the proposed combination with respect to the two methods considered separately."}],"keyword":["Applied Mathematics","Computational Theory and Mathematics","Computational Mathematics","Analysis"],"scopus_import":"1","isi":1,"publication_identifier":{"issn":["1615-3375"],"eissn":["1615-3383"]},"year":"2021","month":"08","project":[{"_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854","name":"IST Austria Open Access Fund"}],"department":[{"_id":"MaMo"}],"article_type":"original","publisher":"Springer","ddc":["510"],"file":[{"file_id":"10542","creator":"alisjak","relation":"main_file","file_name":"2021_Springer_Mondelli.pdf","file_size":2305731,"success":1,"checksum":"9ea12dd8045a0678000a3a59295221cb","date_created":"2021-12-13T15:47:54Z","access_level":"open_access","content_type":"application/pdf","date_updated":"2021-12-13T15:47:54Z"}],"oa_version":"Published Version","type":"journal_article","_id":"10211","publication_status":"published","external_id":{"isi":["000685721000001"],"arxiv":["2008.03326"]},"doi":"10.1007/s10208-021-09531-x","file_date_updated":"2021-12-13T15:47:54Z","article_processing_charge":"Yes (via OA deal)","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"publication":"Foundations of Computational Mathematics","acknowledgement":"M.

In the stochastic population protocol model, a collection of n indistinguishable, resource-limited nodes collectively solve tasks via pairwise interactions. In each interaction, two randomly chosen neighbors first read each other’s states, and then update their local states. A rich line of research has established tight upper and lower bounds on the complexity of fundamental tasks, such as majority and leader election, in this model, when G is a clique. Specifically, in the clique, these tasks can be solved fast, i.e., in n polylog n pairwise interactions, with high probability, using at most polylog n states per node. In this work, we consider the more general setting where G is an arbitrary graph, and present a technique for simulating protocols designed for fully-connected networks in any connected regular graph. Our main result is a simulation that is efficient on many interesting graph families: roughly, the simulation overhead is polylogarithmic in the number of nodes, and quadratic in the conductance of the graph. As an example, this implies that, in any regular graph with conductance φ, both leader election and exact majority can be solved in φ^{-2} ⋅ n polylog n pairwise interactions, with high probability, using at most φ^{-2} ⋅ polylog n states per node. This shows that there are fast and space-efficient population protocols for leader election and exact majority on graphs with good expansion properties."}],"language":[{"iso":"eng"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2023-02-21T09:24:08Z","status":"public","author":[{"id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","first_name":"Dan-Adrian","orcid":"0000-0003-3650-940X","last_name":"Alistarh","full_name":"Alistarh, Dan-Adrian"},{"first_name":"Rati","last_name":"Gelashvili","full_name":"Gelashvili, Rati"},{"orcid":"0000-0002-6432-6646","last_name":"Rybicki","full_name":"Rybicki, Joel","first_name":"Joel","id":"334EFD2E-F248-11E8-B48F-1D18A9856A87"}],"publication_status":"published","alternative_title":["LIPIcs"],"external_id":{"arxiv":["2102.08808"]},"_id":"10218","oa_version":"Published Version","type":"conference","file":[{"date_updated":"2021-11-12T08:16:44Z","content_type":"application/pdf","access_level":"open_access","date_created":"2021-11-12T08:16:44Z","file_size":534219,"success":1,"checksum":"fd2a690f6856d21247e9aa952b0e2885","file_name":"2021_LIPIcsDISC_Alistarh.pdf","relation":"main_file","creator":"cchlebak","file_id":"10274"}],"ddc":["000"],"publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","department":[{"_id":"DaAl"}],"project":[{"grant_number":"840605","call_identifier":"H2020","name":"Coordination in constrained and natural distributed systems","_id":"26A5D39A-B435-11E9-9278-68D0E5697425"}],"month":"10","year":"2021","publication_identifier":{"issn":["1868-8969"],"isbn":["9-783-9597-7210-5"]},"date_published":"2021-10-04T00:00:00Z","intvolume":"       209","has_accepted_license":"1","publication":"35th International Symposium on Distributed Computing","acknowledgement":"This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 840605.","day":"04","volume":209,"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"ec_funded":1,"article_processing_charge":"No","file_date_updated":"2021-11-12T08:16:44Z","doi":"10.4230/LIPIcs.DISC.2021.43","arxiv":1,"quality_controlled":"1","conference":{"end_date":"2021-10-08","location":"Freiburg, Germany","start_date":"2021-10-04","name":"DISC: Distributed Computing "},"citation":{"mla":"Alistarh, Dan-Adrian, et al. “Brief Announcement: Fast Graphical Population Protocols.” <i>35th International Symposium on Distributed Computing</i>, vol. 209, 43, Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2021, doi:<a href=\"https://doi.org/10.4230/LIPIcs.DISC.2021.43\">10.4230/LIPIcs.DISC.2021.43</a>.","chicago":"Alistarh, Dan-Adrian, Rati Gelashvili, and Joel Rybicki. “Brief Announcement: Fast Graphical Population Protocols.” In <i>35th International Symposium on Distributed Computing</i>, Vol. 209.

An almost r-embedding is a map f: K → ℝd such that the images of any r pairwise disjoint simplices of K do not have a common point. We show that if r is not a prime power and d ≥ 2r + 1, then there is a counterexample to the topological Tverberg conjecture, i.e., there is an almost r-embedding of the (d +1)(r − 1)-simplex in ℝd. This improves on previous constructions of counterexamples (for d ≥ 3r) based on a series of papers by M. Özaydin, M. Gromov, P. Blagojević, F. Frick, G. Ziegler, and the second and fourth present authors.\r\n\r\nThe counterexamples are obtained by proving the following algebraic criterion in codimension 2: If r ≥ 3 and if K is a finite 2(r − 1)-complex, then there exists an almost r-embedding K → ℝ2r if and only if there exists a general position PL map f: K → ℝ2r such that the algebraic intersection number of the f-images of any r pairwise disjoint simplices of K is zero. This result can be restated in terms of a cohomological obstruction and extends an analogous codimension 3 criterion by the second and fourth authors. As another application, we classify ornaments f: S3 ⊔ S3 ⊔ S3 → ℝ5 up to ornament concordance.\r\n\r\nIt follows from work of M. Freedman, V. Krushkal and P. Teichner that the analogous criterion for r = 2 is false. We prove a lemma on singular higher-dimensional Borromean rings, yielding an elementary proof of the counterexample.","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1511.03501","open_access":"1"}],"related_material":{"record":[{"status":"public","relation":"earlier_version","id":"8183"},{"id":"9308","status":"public","relation":"earlier_version"}]},"scopus_import":"1","date_updated":"2023-08-14T11:43:55Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"author":[{"last_name":"Avvakumov","full_name":"Avvakumov, Sergey","first_name":"Sergey","id":"3827DAC8-F248-11E8-B48F-1D18A9856A87"},{"id":"32BF9DAA-F248-11E8-B48F-1D18A9856A87","first_name":"Isaac","last_name":"Mabillard","full_name":"Mabillard, Isaac"},{"first_name":"Arkadiy B.","full_name":"Skopenkov, Arkadiy B.","last_name":"Skopenkov"},{"full_name":"Wagner, Uli","last_name":"Wagner","orcid":"0000-0002-1494-0568","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","first_name":"Uli"}],"status":"public","type":"journal_article","oa_version":"Preprint","_id":"10220","publication_status":"published","external_id":{"arxiv":["1511.03501"],"isi":["000712942100013"]},"publisher":"Springer Nature","department":[{"_id":"UlWa"}],"article_type":"original","isi":1,"publication_identifier":{"eissn":["1565-8511"],"issn":["0021-2172"]},"year":"2021","month":"10","project":[{"name":"Algorithms for Embeddings and Homotopy Theory","call_identifier":"FWF","_id":"26611F5C-B435-11E9-9278-68D0E5697425","grant_number":"P31312"}]},{"title":"Eigenstate thermalization hypothesis for Wigner matrices","page":"1005–1048","quality_controlled":"1","arxiv":1,"date_created":"2021-11-07T23:01:25Z","citation":{"ama":"Cipolloni G, Erdös L, Schröder DJ.
