In this paper, we provide a sober look at recent progress in the field and challenge some common assumptions. We first theoretically show that the unsupervised learning of disentangled representations is fundamentally impossible without inductive biases on both the models and the data. Then, we train over 14000\r\n models covering most prominent methods and evaluation metrics in a reproducible large-scale experimental study on eight data sets. We observe that while the different methods successfully enforce properties “encouraged” by the corresponding losses, well-disentangled models seemingly cannot be identified without supervision. Furthermore, different evaluation metrics do not always agree on what should be considered “disentangled” and exhibit systematic differences in the estimation. Finally, increased disentanglement does not seem to necessarily lead to a decreased sample complexity of learning for downstream tasks. Our results suggest that future work on disentanglement learning should be explicit about the role of inductive biases and (implicit) supervision, investigate concrete benefits of enforcing disentanglement of the learned representations, and consider a reproducible experimental setup covering several data sets."}],"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"},"department":[{"_id":"FrLo"}],"author":[{"first_name":"Francesco","id":"26cfd52f-2483-11ee-8040-88983bcc06d4","orcid":"0000-0002-4850-0683","last_name":"Locatello","full_name":"Locatello, Francesco"},{"first_name":"Stefan","last_name":"Bauer","full_name":"Bauer, Stefan"},{"last_name":"Lucic","first_name":"Mario","full_name":"Lucic, Mario"},{"first_name":"Gunnar","last_name":"Rätsch","full_name":"Rätsch, Gunnar"},{"full_name":"Gelly, Sylvain","first_name":"Sylvain","last_name":"Gelly"},{"last_name":"Schölkopf","first_name":"Bernhard","full_name":"Schölkopf, Bernhard"},{"full_name":"Bachem, Olivier","last_name":"Bachem","first_name":"Olivier"}],"title":"A sober look at the unsupervised learning of disentangled representations and their evaluation","main_file_link":[{"open_access":"1","url":"https://jmlr.csail.mit.edu/papers/v21/19-976.html"}],"arxiv":1,"type":"journal_article","month":"09","publication":"Journal of Machine Learning Research","has_accepted_license":"1","external_id":{"arxiv":["2010.14766"]},"citation":{"ieee":"F.

Yet, most deep learning approaches learn distributed representations that do not capture the compositional properties of natural scenes. In this paper, we present the Slot Attention module, an architectural component that interfaces with perceptual representations such as the output of a convolutional neural network and produces a set of task-dependent abstract representations which we call slots. These slots are exchangeable and can bind to any object in the input by specializing through a competitive procedure over multiple rounds of attention. We empirically demonstrate that Slot Attention can extract object-centric representations that enable generalization to unseen compositions when trained on unsupervised object discovery and supervised property prediction tasks.\r\n\r\n"}],"quality_controlled":"1","department":[{"_id":"FrLo"}],"author":[{"full_name":"Locatello, Francesco","last_name":"Locatello","orcid":"0000-0002-4850-0683","first_name":"Francesco","id":"26cfd52f-2483-11ee-8040-88983bcc06d4"},{"first_name":"Dirk","last_name":"Weissenborn","full_name":"Weissenborn, Dirk"},{"first_name":"Thomas","last_name":"Unterthiner","full_name":"Unterthiner, Thomas"},{"full_name":"Mahendran, Aravindh","first_name":"Aravindh","last_name":"Mahendran"},{"last_name":"Heigold","first_name":"Georg","full_name":"Heigold, Georg"},{"last_name":"Uszkoreit","first_name":"Jakob","full_name":"Uszkoreit, Jakob"},{"last_name":"Dosovitskiy","first_name":"Alexey","full_name":"Dosovitskiy, Alexey"},{"last_name":"Kipf","first_name":"Thomas","full_name":"Kipf, Thomas"}],"conference":{"end_date":"2020-12-12","location":"Virtual","name":"NeurIPS: Neural Information Processing Systems","start_date":"2020-12-06"},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","publisher":"Neural Information Processing Systems Foundation","date_published":"2020-12-20T00:00:00Z","page":"11525-11538","_id":"14326","intvolume":"        33","alternative_title":["Advances in Neural Information Processing Systems"],"date_created":"2023-09-13T12:03:46Z","language":[{"iso":"eng"}],"publication_status":"published","status":"public","date_updated":"2025-07-10T11:50:47Z","article_processing_charge":"No","day":"20","volume":33,"oa":1,"oa_version":"Preprint","external_id":{"arxiv":["2006.15055"]},"year":"2020","citation":{"apa":"Locatello, F., Weissenborn, D., Unterthiner, T., Mahendran, A., Heigold, G., Uszkoreit, J., … Kipf, T.

However, a major challenge still lies in the efficient and reproducible preparation of adherent cells for subsequent cryo-EM analysis. This is due to the sensitivity of many cellular specimens to the varying seeding and culturing conditions required for EM experiments, the often limited amount of cellular material and also the fragility of EM grids and their substrate. Here, we present low-cost and reusable 3D printed grid holders, designed to improve specimen preparation when culturing challenging cellular samples directly on grids. The described grid holders increase cell culture reproducibility and throughput, and reduce the resources required for cell culturing. We show that grid holders can be integrated into various cryo-EM workflows, including micro-patterning approaches to control cell seeding on grids, and for generating samples for cryo-focused ion beam milling and cryo-electron tomography experiments. Their adaptable design allows for the generation of specialized grid holders customized to a large variety of applications."}],"article_processing_charge":"No","day":"01","file":[{"success":1,"file_id":"14593","file_name":"3Dprint-files_download_v2.zip","date_created":"2023-11-22T14:58:44Z","relation":"main_file","checksum":"0108616e2a59e51879ea51299a29b091","access_level":"open_access","date_updated":"2023-11-22T14:58:44Z","file_size":49297,"creator":"fschur","content_type":"application/zip"},{"date_created":"2023-12-01T10:39:59Z","file_name":"readme.txt","file_id":"14637","success":1,"checksum":"4c66ddedee4d01c1c4a7978208350cfc","access_level":"open_access","relation":"main_file","creator":"cchlebak","file_size":641,"date_updated":"2023-12-01T10:39:59Z","content_type":"text/plain"}],"file_date_updated":"2023-12-01T10:39:59Z","project":[{"name":"Structure and isoform diversity of the Arp2/3 complex","_id":"9B954C5C-BA93-11EA-9121-9846C619BF3A","grant_number":"P33367"}]},{"keyword":["General Mathematics"],"corr_author":"1","type":"journal_article","arxiv":1,"publication_identifier":{"eissn":["1431-0643"],"issn":["1431-0635"]},"related_material":{"record":[{"id":"6183","relation":"earlier_version","status":"public"}]},"title":"The Dyson equation with linear self-energy: Spectral bands, edges and cusps","department":[{"_id":"LaEr"}],"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"},"author":[{"first_name":"Johannes","id":"36D3D8B6-F248-11E8-B48F-1D18A9856A87","last_name":"Alt","full_name":"Alt, Johannes"},{"full_name":"Erdös, László","orcid":"0000-0001-5366-9603","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","first_name":"László","last_name":"Erdös"},{"full_name":"Krüger, Torben H","id":"3020C786-F248-11E8-B48F-1D18A9856A87","first_name":"Torben H","orcid":"0000-0002-4821-3297","last_name":"Krüger"}],"abstract":[{"lang":"eng","text":"We study the unique solution m of the Dyson equation \\( -m(z)^{-1} = z\\1 - a + S[m(z)] \\) on a von Neumann algebra A with the constraint Imm≥0. Here, z lies in the complex upper half-plane, a is a self-adjoint element of A and S is a positivity-preserving linear operator on A. We show that m is the Stieltjes transform of a compactly supported A-valued measure on R. Under suitable assumptions, we establish that this measure has a uniformly 1/3-Hölder continuous density with respect to the Lebesgue measure, which is supported on finitely many intervals, called bands. In fact, the density is analytic inside the bands with a square-root growth at the edges and internal cubic root cusps whenever the gap between two bands vanishes. The shape of these singularities is universal and no other singularity may occur. We give a precise asymptotic description of m near the singular points. These asymptotics generalize the analysis at the regular edges given in the companion paper on the Tracy-Widom universality for the edge eigenvalue statistics for correlated random matrices [the first author et al., Ann. Probab. 48, No. 2, 963--1001 (2020; Zbl 1434.60017)] and they play a key role in the proof of the Pearcey universality at the cusp for Wigner-type matrices [G. Cipolloni et al., Pure Appl.

To understand this phenomenon at the molecular level, we present the first four crystal structures of heterodimeric septin complexes. We describe in detail the two distinct types of G-interface present within the octameric particles, which must polymerize to form filaments. These are formed between SEPT2 and SEPT6 and between SEPT7 and SEPT3, and their description permits an understanding of the structural basis for the selectivity necessary for correct filament assembly. By replacing SEPT6 by SEPT8 or SEPT11, it is possible to rationalize Kinoshita's postulate, which predicts the exchangeability of septins from within a subgroup. Switches I and II, which in classical small GTPases provide a mechanism for nucleotide-dependent conformational change, have been repurposed in septins to play a fundamental role in molecular recognition. Specifically, it is switch I which holds the key to discriminating between the two different G-interfaces. Moreover, residues which are characteristic for a given subgroup play subtle, but pivotal, roles in guaranteeing that the correct interfaces are formed.","lang":"eng"}],"article_type":"original","publisher":"Elsevier","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"date_created":"2024-02-28T08:50:34Z","issue":"21","intvolume":"       432","_id":"15036","page":"5784-5801","date_published":"2020-10-02T00:00:00Z","pmid":1},{"external_id":{"pmid":["32087370"]},"citation":{"ieee":"J.

It is regulated by ubiquitination, a post-translational modification crucial for the proper sorting of endocytosed PM proteins to the vacuole for subsequent degradation. To understand the significance and the variety of roles played by this reversible modification, the function of ubiquitin receptors, which translate the ubiquitin signature into a cellular response, needs to be elucidated. In this study, we show that TOL (TOM1-like) proteins function in plants as multivalent ubiquitin receptors, governing ubiquitinated cargo delivery to the vacuole via the conserved Endosomal Sorting Complex Required for Transport (ESCRT) pathway. TOL2 and TOL6 interact with components of the ESCRT machinery and bind to K63-linked ubiquitin via two tandemly arranged conserved ubiquitin-binding domains. Mutation of these domains results not only in a loss of ubiquitin binding but also altered localization, abolishing TOL6 ubiquitin receptor activity. Function and localization of TOL6 is itself regulated by ubiquitination, whereby TOL6 ubiquitination potentially modulates degradation of PM-localized cargoes, assisting in the fine-tuning of the delicate interplay between protein recycling and downregulation. Taken together, our findings demonstrate the function and regulation of a ubiquitin receptor that mediates vacuolar degradation of PM proteins in higher plants."}]},{"status":"public","publication_status":"published","doi":"10.1609/aaai.v34i06.6531","date_updated":"2025-04-15T06:30:08Z","project":[{"grant_number":"S11407","call_identifier":"FWF","_id":"25863FF4-B435-11E9-9278-68D0E5697425","name":"Game Theory"}],"volume":34,"article_processing_charge":"No","day":"03","oa_version":"Preprint","oa":1,"citation":{"ieee":"T.

A classical optimization criterion for MDPs is to maximize the expected discounted-sum payoff, which ignores low probability catastrophic events with highly negative impact on the system. On the other hand, risk-averse policies require the probability of undesirable events to be below a given threshold, but they do not account for optimization of the expected payoff. We consider MDPs with discounted-sum payoff with failure states which represent catastrophic outcomes. The objective of risk-constrained planning is to maximize the expected discounted-sum payoff among risk-averse policies that ensure the probability to encounter a failure state is below a desired threshold. Our main contribution is an efficient risk-constrained planning algorithm that combines UCT-like search with a predictor learned through interaction with the MDP (in the style of AlphaZero) and with a risk-constrained action selection via linear programming. We demonstrate the effectiveness of our approach with experiments on classical MDPs from the literature, including benchmarks with an order of 106 states.</jats:p>","lang":"eng"}],"author":[{"last_name":"Brázdil","first_name":"Tomáš","full_name":"Brázdil, Tomáš"},{"full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","last_name":"Chatterjee"},{"full_name":"Novotný, Petr","last_name":"Novotný","first_name":"Petr"},{"full_name":"Vahala, Jiří","first_name":"Jiří","last_name":"Vahala"}],"department":[{"_id":"KrCh"}],"conference":{"name":"AAAI: Conference on Artificial Intelligence","location":"New York, NY, United States","start_date":"2020-02-07","end_date":"2020-02-12"},"publisher":"Association for the Advancement of Artificial Intelligence","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"15055","intvolume":"        34","page":"9794-9801","date_published":"2020-04-03T00:00:00Z","language":[{"iso":"eng"}],"acknowledgement":"Krishnendu Chatterjee is supported by the Austrian Science Fund (FWF) NFN Grant No. S11407-N23 (RiSE/SHiNE), and COST Action GAMENET.

VRK-1, the single Caenorhabditis elegans VRK ortholog, functions in cell division and germline proliferation. However, the role of VRK-1 in postmitotic cells and adult life span remains unknown. Here, we show that VRK-1 increases organismal longevity by activating the cellular energy sensor, AMP-activated protein kinase (AMPK), via direct phosphorylation. We found that overexpression of vrk-1 in the soma of adult C. elegans increased life span and, conversely, inhibition of vrk-1 decreased life span. In addition, vrk-1 was required for longevity conferred by mutations that inhibit C. elegans mitochondrial respiration, which requires AMPK. VRK-1 directly phosphorylated and up-regulated AMPK in both C. elegans and cultured human cells. Thus, our data show that the somatic nuclear kinase, VRK-1, promotes longevity through AMPK activation, and this function appears to be conserved between C. elegans and humans.","lang":"eng"}],"quality_controlled":"1","department":[{"_id":"MaDe"}],"tmp":{"short":"CC BY-NC (4.0)","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","image":"/images/cc_by_nc.png","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode"},"author":[{"first_name":"Sangsoon","last_name":"Park","full_name":"Park, Sangsoon"},{"last_name":"Artan","orcid":"0000-0001-8945-6992","id":"C407B586-6052-11E9-B3AE-7006E6697425","first_name":"Murat","full_name":"Artan, Murat"},{"first_name":"Seung Hyun","last_name":"Han","full_name":"Han, Seung Hyun"},{"first_name":"Hae-Eun H.","last_name":"Park","full_name":"Park, Hae-Eun H."},{"full_name":"Jung, Yoonji","last_name":"Jung","first_name":"Yoonji"},{"full_name":"Hwang, Ara B.","last_name":"Hwang","first_name":"Ara B."},{"last_name":"Shin","first_name":"Won Sik","full_name":"Shin, Won Sik"},{"first_name":"Kyong-Tai","last_name":"Kim","full_name":"Kim, Kyong-Tai"},{"first_name":"Seung-Jae V.","last_name":"Lee","full_name":"Lee, Seung-Jae V."}],"title":"VRK-1 extends life span by activation of AMPK via phosphorylation","publication_identifier":{"eissn":["2375-2548"]},"type":"journal_article","date_published":"2020-07-01T00:00:00Z","article_number":"aaw7824","intvolume":"         6","_id":"15057","date_created":"2024-03-04T09:41:57Z","issue":"27","acknowledgement":"This research was supported by grants NRF-2019R1A3B2067745 and NRF-2017R1A5A1015366 funded by the Korean Government (MSIT) through the National Research Foundation (NRF) of Korea to S.-J.V.L. and by grant Basic Science Research Program (No. 2019R1A2C2009440) funded by the Korean Government (MSIT) through the NRF of Korea to K.-T.K.

The proposed radiometer is based on an electro-optic upconverter that boosts up microwave photons energy by upconverting them into an optical domain what makes them immune to thermal noise even if operating at room temperature. The converter uses a high-quality factor whispering gallery\r\nmode (WGM) resonator providing naturally narrow bandwidth and therefore might be useful for applications like microwave hyperspectral sensing. The upconversion process is explained by\r\nproviding essential information about photon conversion efficiency and sensitivity. To prove the concept, we describe an experiment which shows state-of-the-art photon conversion efficiency n=10-5 per mW of pump power at the frequency of 80 GHz.","lang":"eng"}]},{"article_processing_charge":"No","day":"08","volume":117,"oa":1,"oa_version":"Published Version","ddc":["570"],"doi":"10.1073/pnas.1917269117","publication_status":"published","status":"public","date_updated":"2026-06-18T17:45:21Z","acknowledged_ssus":[{"_id":"LifeSc"}],"month":"09","publication":"Proceedings of the National Academy of Sciences of the United States of America","external_id":{"pmid":["32848067"]},"year":"2020","citation":{"apa":"Pinotsis, N., Zielinska, K., Babuta, M., Arolas, J.

Here we report the mechanism of Ca2+-mediated regulation of Entamoeba histolytica α-actinin-2 (EhActn2) with features expected for the common ancestor of Entamoeba and higher eukaryotic α-actinins. Crystal structures of Ca2+-free and Ca2+-bound EhActn2 reveal a calmodulin-like domain (CaMD) uniquely inserted within the rod domain. Integrative studies reveal an exceptionally high affinity of the EhActn2 CaMD for Ca2+, binding of which can only be regulated in the presence of physiological concentrations of Mg2+. Ca2+ binding triggers an increase in protein multidomain rigidity, reducing conformational flexibility of F-actin–binding domains via interdomain cross-talk and consequently inhibiting F-actin bundling. In vivo studies uncover that EhActn2 plays an important role in phagocytic cup formation and might constitute a new drug target for amoebic dysentery.","lang":"eng"}],"quality_controlled":"1","department":[{"_id":"CaBe"}],"author":[{"full_name":"Pinotsis, Nikos","first_name":"Nikos","last_name":"Pinotsis"},{"first_name":"Karolina","last_name":"Zielinska","full_name":"Zielinska, Karolina"},{"full_name":"Babuta, Mrigya","last_name":"Babuta","first_name":"Mrigya"},{"first_name":"Joan L.","last_name":"Arolas","full_name":"Arolas, Joan L."},{"full_name":"Kostan, Julius","first_name":"Julius","last_name":"Kostan"},{"first_name":"Muhammad Bashir","last_name":"Khan","full_name":"Khan, Muhammad Bashir"},{"first_name":"Claudia","last_name":"Schreiner","full_name":"Schreiner, Claudia"},{"full_name":"Testa Salmazo, Anita P","last_name":"Testa Salmazo","first_name":"Anita P","id":"41F1F098-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Ciccarelli","first_name":"Luciano","full_name":"Ciccarelli, Luciano"},{"full_name":"Puchinger, Martin","last_name":"Puchinger","first_name":"Martin"},{"first_name":"Eirini A.","last_name":"Gkougkoulia","full_name":"Gkougkoulia, Eirini A."},{"full_name":"Ribeiro, Euripedes de Almeida","first_name":"Euripedes de Almeida","last_name":"Ribeiro"},{"full_name":"Marlovits, Thomas C.","first_name":"Thomas C.","last_name":"Marlovits"},{"full_name":"Bhattacharya, Alok","last_name":"Bhattacharya","first_name":"Alok"},{"first_name":"Kristina","last_name":"Djinovic-Carugo","full_name":"Djinovic-Carugo, Kristina"}],"title":"Calcium modulates the domain flexibility and function of an α-actinin similar to the ancestral α-actinin","main_file_link":[{"url":"https://doi.org/10.1073/pnas.191726911","open_access":"1"}],"publication_identifier":{"issn":["0027-8424"],"eissn":["1091-6490"]},"type":"journal_article","date_published":"2020-09-08T00:00:00Z","pmid":1,"page":"22101-22112","_id":"15061","intvolume":"       117","issue":"36","date_created":"2024-03-04T10:03:52Z","acknowledgement":"We thank the staff of the macromolecular crystallography (MX) and SAXS beamlines at the European Synchrotron Radiation facility, Diamond, and Swiss Light Source for excellent support, and the Life Sciences Facility of the Institute of Science and Technology Austria for usage of the rheometer.

In the same step, the chosen node picks a random neighbor, and the two nodes balance their loads by averaging them. We are interested in the expected gap between the minimum and maximum loads at nodes as the process progresses, and its dependence on n and on the graph structure. Variants of the above graphical balanced allocation process have been studied previously by Peres, Talwar, and Wieder [Peres et al., 2015], and by Sauerwald and Sun [Sauerwald and Sun, 2015]. These authors left as open the question of characterizing the gap in the case of cycle graphs in the dynamic case, where weights are created during the algorithm’s execution. For this case, the only known upper bound is of 𝒪(n log n), following from a majorization argument due to [Peres et al., 2015], which analyzes a related graphical allocation process. In this paper, we provide an upper bound of 𝒪 (√n log n) on the expected gap of the above process for cycles of length n. We introduce a new potential analysis technique, which enables us to bound the difference in load between k-hop neighbors on the cycle, for any k ≤ n/2. We complement this with a \"gap covering\" argument, which bounds the maximum value of the gap by bounding its value across all possible subsets of a certain structure, and recursively bounding the gaps within each subset. We provide analytical and experimental evidence that our upper bound on the gap is tight up to a logarithmic factor."}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/3.0/legalcode","image":"/images/cc_by.png","short":"CC BY (3.0)","name":"Creative Commons Attribution 3.0 Unported (CC BY 3.0)"},"department":[{"_id":"DaAl"}],"author":[{"full_name":"Alistarh, Dan-Adrian","last_name":"Alistarh","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3650-940X","first_name":"Dan-Adrian"},{"id":"3279A00C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5634-0731","first_name":"Giorgi","last_name":"Nadiradze","full_name":"Nadiradze, Giorgi"},{"full_name":"Sabour, Amirmojtaba","last_name":"Sabour","id":"bcc145fd-e77f-11ea-ae8b-80d661dbff67","first_name":"Amirmojtaba"}]},{"doi":"10.4171/owr/2019/56","title":"Random matrices","status":"public","publication_status":"published","publication_identifier":{"issn":["1660-8933"]},"type":"journal_article","date_updated":"2024-03-12T12:25:18Z","day":"19","article_processing_charge":"No","abstract":[{"text":"Large complex systems tend to develop universal patterns that often represent their essential characteristics. For example, the cumulative effects of independent or weakly dependent random variables often yield the Gaussian universality class via the central limit theorem. For non-commutative random variables, e.g. matrices, the Gaussian behavior is often replaced by another universality class, commonly called random matrix statistics. Nearby eigenvalues are strongly correlated, and, remarkably, their correlation structure is universal, depending only on the symmetry type of the matrix. Even more surprisingly, this feature is not restricted to matrices; in fact Eugene Wigner, the pioneer of the field, discovered in the 1950s that distributions of the gaps between energy levels of complicated quantum systems universally follow the same random matrix statistics. This claim has never been rigorously proved for any realistic physical system but experimental data and extensive numerics leave no doubt as to its correctness. Since then random matrices have proved to be extremely useful phenomenological models in a wide range of applications beyond quantum physics that include number theory, statistics, neuroscience, population dynamics, wireless communication and mathematical finance. The ubiquity of random matrices in natural sciences is still a mystery, but recent years have witnessed a breakthrough in the mathematical description of the statistical structure of their spectrum. Random matrices and closely related areas such as log-gases have become an extremely active research area in probability theory.\r\nThis workshop brought together outstanding researchers from a variety of mathematical backgrounds whose areas of research are linked to random matrices. While there are strong links between their motivations, the techniques used by these researchers span a large swath of mathematics, ranging from purely algebraic techniques to stochastic analysis, classical probability theory, operator algebra, supersymmetry, orthogonal polynomials, etc.","lang":"eng"}],"quality_controlled":"1","volume":16,"oa_version":"None","author":[{"full_name":"Erdös, László","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","first_name":"László","orcid":"0000-0001-5366-9603","last_name":"Erdös"},{"full_name":"Götze, Friedrich","last_name":"Götze","first_name":"Friedrich"},{"last_name":"Guionnet","first_name":"Alice","full_name":"Guionnet, Alice"}],"department":[{"_id":"LaEr"}],"article_type":"original","publisher":"European Mathematical Society","year":"2020","citation":{"ieee":"L.
