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.","lang":"eng"}],"date_published":"2021-08-17T00:00:00Z","file_date_updated":"2021-12-13T15:47:54Z","keyword":["Applied Mathematics","Computational Theory and Mathematics","Computational Mathematics","Analysis"],"publication":"Foundations of Computational Mathematics","day":"17","language":[{"iso":"eng"}],"year":"2021","scopus_import":"1","publisher":"Springer","file":[{"success":1,"date_updated":"2021-12-13T15:47:54Z","content_type":"application/pdf","file_name":"2021_Springer_Mondelli.pdf","access_level":"open_access","file_size":2305731,"file_id":"10542","creator":"alisjak","date_created":"2021-12-13T15:47:54Z","checksum":"9ea12dd8045a0678000a3a59295221cb","relation":"main_file"}],"date_created":"2021-11-03T10:59:08Z","project":[{"_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854","name":"IST Austria Open Access Fund"}],"article_type":"original"},{"day":"04","year":"2021","language":[{"iso":"eng"}],"publication":"35th International Symposium on Distributed Computing","file_date_updated":"2021-11-12T09:23:22Z","abstract":[{"lang":"eng","text":"This paper reports a new concurrent graph data structure that supports updates of both edges and vertices and queries: Breadth-first search, Single-source shortest-path, and Betweenness centrality.

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.

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.

A prominent example of this is the response to gravity, in which shoots bend up and roots bend down1. This paradox is based on opposite effects of the phytohormone auxin, which promotes cell expansion in shoots while inhibiting it in roots via a yet unknown cellular mechanism2. Here, by combining microfluidics, live imaging, genetic engineering and phosphoproteomics in Arabidopsis thaliana, we advance understanding of how auxin inhibits root growth. We show that auxin activates two distinct, antagonistically acting signalling pathways that converge on rapid regulation of apoplastic pH, a causative determinant of growth. Cell surface-based TRANSMEMBRANE KINASE1 (TMK1) interacts with and mediates phosphorylation and activation of plasma membrane H+-ATPases for apoplast acidification, while intracellular canonical auxin signalling promotes net cellular H+ influx, causing apoplast alkalinization. Simultaneous activation of these two counteracting mechanisms poises roots for rapid, fine-tuned growth modulation in navigating complex soil environments.","lang":"eng"}],"author":[{"orcid":"0000-0002-5607-272X","first_name":"Lanxin","last_name":"Li","id":"367EF8FA-F248-11E8-B48F-1D18A9856A87","full_name":"Li, Lanxin"},{"id":"362BF7FE-F248-11E8-B48F-1D18A9856A87","full_name":"Verstraeten, Inge","orcid":"0000-0001-7241-2328","last_name":"Verstraeten","first_name":"Inge"},{"full_name":"Roosjen, Mark","first_name":"Mark","last_name":"Roosjen"},{"last_name":"Takahashi","first_name":"Koji","full_name":"Takahashi, Koji"},{"first_name":"Lesia","last_name":"Rodriguez Solovey","orcid":"0000-0002-7244-7237","full_name":"Rodriguez Solovey, Lesia","id":"3922B506-F248-11E8-B48F-1D18A9856A87"},{"id":"4515C308-F248-11E8-B48F-1D18A9856A87","full_name":"Merrin, Jack","first_name":"Jack","last_name":"Merrin","orcid":"0000-0001-5145-4609"},{"full_name":"Chen, Jian","first_name":"Jian","last_name":"Chen"},{"first_name":"Lana","last_name":"Shabala","full_name":"Shabala, Lana"},{"full_name":"Smet, Wouter","last_name":"Smet","first_name":"Wouter"},{"last_name":"Ren","first_name":"Hong","full_name":"Ren, Hong"},{"full_name":"Vanneste, Steffen","first_name":"Steffen","last_name":"Vanneste"},{"last_name":"Shabala","first_name":"Sergey","full_name":"Shabala, Sergey"},{"full_name":"De Rybel, Bert","first_name":"Bert","last_name":"De Rybel"},{"first_name":"Dolf","last_name":"Weijers","full_name":"Weijers, Dolf"},{"first_name":"Toshinori","last_name":"Kinoshita","full_name":"Kinoshita, Toshinori"},{"full_name":"Gray, William M.","last_name":"Gray","first_name":"William M."},{"last_name":"Friml","first_name":"Jiří","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jiří"}],"article_type":"original","project":[{"grant_number":"742985","call_identifier":"H2020","name":"Tracing Evolution of Auxin Transport and Polarity in Plants","_id":"261099A6-B435-11E9-9278-68D0E5697425"},{"grant_number":"I03630","call_identifier":"FWF","_id":"26538374-B435-11E9-9278-68D0E5697425","name":"Molecular mechanisms of endocytic cargo recognition in plants"},{"_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program","call_identifier":"H2020","grant_number":"665385"},{"grant_number":"25351","_id":"26B4D67E-B435-11E9-9278-68D0E5697425","name":"A Case Study of Plant Growth Regulation: Molecular Mechanism of Auxin-mediated Rapid Growth Inhibition in Arabidopsis Root"}],"date_created":"2021-11-07T23:01:25Z","main_file_link":[{"url":"https://www.doi.org/10.21203/rs.3.rs-266395/v3","open_access":"1"}],"pmid":1,"publisher":"Springer Nature","scopus_import":"1","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","related_material":{"record":[{"relation":"earlier_version","id":"10095","status":"public"}],"link":[{"url":"https://ist.ac.at/en/news/stop-and-grow/","relation":"press_release","description":"News on IST Webpage"}]},"oa_version":"Preprint","month":"11","publication_identifier":{"issn":["00280836"],"eissn":["14764687"]},"date_updated":"2024-10-29T10:22:45Z","publication_status":"published","oa":1,"intvolume":"       599","page":"273-277","_id":"10223","external_id":{"pmid":["34707283"],"isi":["000713338100006"]},"doi":"10.1038/s41586-021-04037-6","department":[{"_id":"JiFr"},{"_id":"NanoFab"}],"quality_controlled":"1","acknowledgement":"We thank N.

How independent organs achieve anisotropic shapes and polarities is poorly understood. To address this question, we constructed a mechano-biochemical model for Arabidopsis root meristem growth that integrates biologically plausible principles. Computer model simulations demonstrate how differential growth of neighboring tissues results in the initial symmetry-breaking leading to anisotropic root growth. Furthermore, the root growth feeds back on a polar transport network of the growth regulator auxin. Model, predictions are in close agreement with in vivo patterns of anisotropic growth, auxin distribution, and cell polarity, as well as several root phenotypes caused by chemical, mechanical, or genetic perturbations. Our study demonstrates that the combination of tissue mechanics and polar auxin transport organizes anisotropic root growth and cell polarities during organ outgrowth. Therefore, a mobile auxin signal transported through immobile cells drives polarity and growth mechanics to coordinate complex organ development.","lang":"eng"}],"volume":10,"publication":"eLife","year":"2021","language":[{"iso":"eng"}],"day":"01"},{"month":"10","oa_version":"Published Version","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","oa":1,"publication_status":"published","ddc":["610"],"date_updated":"2023-08-14T11:43:23Z","publication_identifier":{"eissn":["1664-302X"]},"has_accepted_license":"1","article_number":"760017","doi":"10.3389/fmicb.2021.760017","external_id":{"isi":["000715997300001"],"pmid":["34745067"]},"_id":"10271","intvolume":"        12","acknowledgement":"High-throughput sequencing data were generated by the Vienna BioCenter Core Facilities.

Using the interactions between the antifolate drug trimethoprim and the ribosome-targeting antibiotic erythromycin in Escherichia coli as a model, we applied a transcriptomic approach for dissecting interactions between two antibiotics with different modes of action. When trimethoprim and erythromycin were combined, the transcriptional response of genes from the sulfate reduction pathway deviated from the dominant effect of trimethoprim on the transcriptome. We successfully altered the drug interaction from additivity to suppression by increasing the sulfate level in the growth environment and identified sulfate reduction as an important metabolic determinant that shapes the interaction between the two drugs. Our work highlights the potential of using prioritization of gene expression patterns as a tool for identifying key metabolic determinants that shape drug-drug interactions. We further demonstrated that the sigma factor-binding protein gene crl shapes the interactions between the two antibiotics, which provides a rare example of how naturally occurring variations between strains of the same bacterial species can sometimes generate very different drug interactions.","lang":"eng"}],"date_published":"2021-10-20T00:00:00Z","article_type":"original","project":[{"grant_number":"P27201-B22","call_identifier":"FWF","name":"Revealing the mechanisms underlying drug interactions","_id":"25E9AF9E-B435-11E9-9278-68D0E5697425"},{"_id":"25E83C2C-B435-11E9-9278-68D0E5697425","name":"Optimality principles in responses to antibiotics","grant_number":"303507","call_identifier":"FP7"}],"date_created":"2021-11-11T10:39:37Z","file":[{"file_name":"2021_FrontiersMicrob_Qi.pdf","access_level":"open_access","file_size":2397203,"date_updated":"2021-11-11T10:54:40Z","content_type":"application/pdf","creator":"cchlebak","date_created":"2021-11-11T10:54:40Z","relation":"main_file","checksum":"d41321748e9588dd3cf03e9a7222127f","file_id":"10272","success":1}],"publisher":"Frontiers","pmid":1,"scopus_import":"1"},{"scopus_import":"1","pmid":1,"publisher":"Springer Nature","file":[{"success":1,"file_id":"10292","relation":"main_file","checksum":"1c392b12b9b7b615d422d9fabe19cdb9","date_created":"2021-11-15T13:25:52Z","creator":"cchlebak","content_type":"application/pdf","date_updated":"2021-11-15T13:25:52Z","file_size":6282703,"access_level":"open_access","file_name":"2021_NatComm_Aubret.pdf"}],"date_created":"2021-11-14T23:01:23Z","article_type":"original","date_published":"2021-11-04T00:00:00Z","abstract":[{"lang":"eng","text":"Machines enabled the Industrial Revolution and are central to modern technological progress: A machine’s parts transmit forces, motion, and energy to one another in a predetermined manner. Today’s engineering frontier, building artificial micromachines that emulate the biological machinery of living organisms, requires faithful assembly and energy consumption at the microscale. Here, we demonstrate the programmable assembly of active particles into autonomous metamachines using optical templates. Metamachines, or machines made of machines, are stable, mobile and autonomous architectures, whose dynamics stems from the geometry. We use the interplay between anisotropic force generation of the active colloids with the control of their orientation by local geometry. This allows autonomous reprogramming of active particles of the metamachines to achieve multiple functions. It permits the modular assembly of metamachines by fusion, reconfiguration of metamachines and, we anticipate, a shift in focus of self-assembly towards active matter and reprogrammable materials."}],"volume":12,"author":[{"full_name":"Aubret, Antoine","first_name":"Antoine","last_name":"Aubret"},{"last_name":"Martinet","first_name":"Quentin","orcid":"0000-0002-2916-6632","id":"b37485a8-d343-11eb-a0e9-df8c484ef8ab","full_name":"Martinet, Quentin"},{"first_name":"Jérémie A","last_name":"Palacci","orcid":"0000-0002-7253-9465","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","full_name":"Palacci, Jérémie A"}],"issue":"1","file_date_updated":"2021-11-15T13:25:52Z","year":"2021","language":[{"iso":"eng"}],"day":"04","publication":"Nature Communications","type":"journal_article","status":"public","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"title":"Metamachines of pluripotent colloids","isi":1,"article_processing_charge":"Yes","citation":{"ieee":"A.

These syndromes show a broad variety of somatic phenotypes including cancers, skin abnormalities, heart disease and facial dysmorphisms. Less well studied are the neuropsychiatric symptoms such as ASD. Here, we assess the relevance of these signalopathies in ASD reviewing genetic, human cell model, rodent studies and clinical trials. We conclude that signalopathies have an increased liability for ASD and that, in particular, ASD individuals with dysmorphic features and intellectual disability (ID) have a higher chance for disruptive mutations in RAS- and mTOR-related genes. Studies on rodent and human cell models confirm aberrant neuronal development as the underlying pathology. Human studies further suggest that multiple hits are necessary to induce the respective phenotypes. Recent clinical trials do only report improvements for comorbid conditions such as epilepsy or cancer but not for behavioral aspects. Animal models show that treatment during early development can rescue behavioral phenotypes. Taken together, we suggest investigating the differential roles of mTOR and RAS signaling in both human and rodent models, and to test drug treatment both during and after neuronal development in the available model systems"}],"volume":12,"author":[{"full_name":"Vasic, Verica","last_name":"Vasic","first_name":"Verica"},{"last_name":"Jones","first_name":"Mattson S.O.","full_name":"Jones, Mattson S.O."},{"full_name":"Haslinger, Denise","id":"76922BDA-3D3B-11EA-90BD-A44F3DDC885E","last_name":"Haslinger","first_name":"Denise"},{"first_name":"Lisa","last_name":"Knaus","full_name":"Knaus, Lisa","id":"3B2ABCF4-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Schmeisser, Michael J.","first_name":"Michael J.","last_name":"Schmeisser"},{"first_name":"Gaia","last_name":"Novarino","orcid":"0000-0002-7673-7178","id":"3E57A680-F248-11E8-B48F-1D18A9856A87","full_name":"Novarino, Gaia"},{"first_name":"Andreas G.","last_name":"Chiocchetti","full_name":"Chiocchetti, Andreas G."}]},{"publication_identifier":{"issn":["0028-646X"],"eissn":["1469-8137"]},"date_updated":"2023-08-14T11:46:43Z","publication_status":"published","oa":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","oa_version":"Preprint","month":"11","type":"journal_article","status":"public","title":"Mutually opposing activity of PIN7 splicing isoforms is required for auxin-mediated tropic responses in Arabidopsis thaliana","isi":1,"article_processing_charge":"No","citation":{"ista":"Kashkan I, Hrtyan M, Retzer K, Humpolíčková J, Jayasree A, Filepová R, Vondráková Z, Simon S, Rombaut D, Jacobs TB, Frilander MJ, Hejátko J, Friml J, Petrášek J, Růžička K. 2021.

Nonetheless, little effort has been dedicated to investigating the functional relevance of particular splicing events, even those in the key developmental and hormonal regulators. Combining approaches of genetics, biochemistry and advanced confocal microscopy, we describe the impact of alternative splicing on the PIN7 gene in the model plant Arabidopsis thaliana. PIN7 encodes a polarly localized transporter for the phytohormone auxin and produces two evolutionarily conserved transcripts, PIN7a and PIN7b. PIN7a and PIN7b, differing in a four amino acid stretch, exhibit almost identical expression patterns and subcellular localization. We reveal that they are closely associated and mutually influence each other's mobility within the plasma membrane. Phenotypic complementation tests indicate that the functional contribution of PIN7b per se is minor, but it markedly reduces the prominent PIN7a activity, which is required for correct seedling apical hook formation and auxin-mediated tropic responses. Our results establish alternative splicing of the PIN family as a conserved, functionally relevant mechanism, revealing an additional regulatory level of auxin-mediated plant development.","lang":"eng"}],"volume":233,"author":[{"first_name":"Ivan","last_name":"Kashkan","full_name":"Kashkan, Ivan"},{"last_name":"Hrtyan","first_name":"Mónika","full_name":"Hrtyan, Mónika","id":"45A71A74-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Retzer","first_name":"Katarzyna","full_name":"Retzer, Katarzyna"},{"first_name":"Jana","last_name":"Humpolíčková","full_name":"Humpolíčková, Jana"},{"last_name":"Jayasree","first_name":"Aswathy","full_name":"Jayasree, Aswathy"},{"full_name":"Filepová, Roberta","last_name":"Filepová","first_name":"Roberta"},{"first_name":"Zuzana","last_name":"Vondráková","full_name":"Vondráková, Zuzana"},{"id":"4542EF9A-F248-11E8-B48F-1D18A9856A87","full_name":"Simon, Sibu","first_name":"Sibu","last_name":"Simon","orcid":"0000-0002-1998-6741"},{"first_name":"Debbie","last_name":"Rombaut","full_name":"Rombaut, Debbie"},{"first_name":"Thomas B.","last_name":"Jacobs","full_name":"Jacobs, Thomas B."},{"first_name":"Mikko J.","last_name":"Frilander","full_name":"Frilander, Mikko J."},{"last_name":"Hejátko","first_name":"Jan","full_name":"Hejátko, Jan"},{"first_name":"Jiří","last_name":"Friml","orcid":"0000-0002-8302-7596","full_name":"Friml, Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Jan","last_name":"Petrášek","full_name":"Petrášek, Jan"},{"first_name":"Kamil","last_name":"Růžička","full_name":"Růžička, Kamil"}],"year":"2021","language":[{"iso":"eng"}],"day":"05","publication":"New Phytologist","scopus_import":"1","main_file_link":[{"url":"https://www.biorxiv.org/content/10.1101/2020.05.02.074070v2","open_access":"1"}],"pmid":1,"publisher":"Wiley","article_type":"original","date_created":"2021-11-14T23:01:24Z"},{"file_date_updated":"2022-05-16T07:07:41Z","author":[{"first_name":"Leonardo","last_name":"Restivo","full_name":"Restivo, Leonardo"},{"full_name":"Gerlach, Björn","last_name":"Gerlach","first_name":"Björn"},{"full_name":"Tsoory, Michael","first_name":"Michael","last_name":"Tsoory"},{"first_name":"Lior","last_name":"Bikovski","full_name":"Bikovski, Lior"},{"full_name":"Badurek, Sylvia","first_name":"Sylvia","last_name":"Badurek"},{"full_name":"Pitzer, Claudia","first_name":"Claudia","last_name":"Pitzer"},{"full_name":"Kos-Braun, Isabelle C.","first_name":"Isabelle C.","last_name":"Kos-Braun"},{"full_name":"Mausset-Bonnefont, Anne Laure Mj","first_name":"Anne Laure Mj","last_name":"Mausset-Bonnefont"},{"full_name":"Ward, Jonathan","last_name":"Ward","first_name":"Jonathan"},{"id":"4272DB4A-F248-11E8-B48F-1D18A9856A87","full_name":"Schunn, Michael","orcid":"0000-0003-4326-5300","first_name":"Michael","last_name":"Schunn"},{"full_name":"Noldus, Lucas P.J.J.","first_name":"Lucas P.J.J.","last_name":"Noldus"},{"full_name":"Bespalov, Anton","first_name":"Anton","last_name":"Bespalov"},{"first_name":"Vootele","last_name":"Voikar","full_name":"Voikar, Vootele"}],"date_published":"2021-11-04T00:00:00Z","volume":22,"abstract":[{"lang":"eng","text":"During the past decade, the scientific community and outside observers have noted a concerning lack of rigor and transparency in preclinical research that led to talk of a “reproducibility crisis” in the life sciences (Baker, 2016; Bespalov & Steckler, 2018; Heddleston et al, 2021). Various measures have been proposed to address the problem: from better training of scientists to more oversight to expanded publishing practices such as preregistration of studies. The recently published EQIPD (Enhancing Quality in Preclinical Data) System is, to date, the largest initiative that aims to establish a systematic approach for increasing the robustness and reliability of biomedical research (Bespalov et al, 2021). However, promoting a cultural change in research practices warrants a broad adoption of the Quality System and its underlying philosophy. It is here that academic Core Facilities (CF), research service providers at universities and research institutions, can make a difference. It is fair to assume that a significant fraction of published data originated from experiments that were designed, run, or analyzed in CFs. These academic services play an important role in the research ecosystem by offering access to cutting-edge equipment and by developing and testing novel techniques and methods that impact research in the academic and private sectors alike (Bikovski et al, 2020). Equipment and infrastructure are not the only value: CFs employ competent personnel with profound knowledge and practical experience of the specific field of interest: animal behavior, imaging, crystallography, genomics, and so on. Thus, CFs are optimally positioned to address concerns about the quality and robustness of preclinical research."}],"publication":"EMBO Reports","language":[{"iso":"eng"}],"year":"2021","day":"04","file":[{"success":1,"date_created":"2022-05-16T07:07:41Z","creator":"dernst","relation":"main_file","checksum":"74743baa6ef431ef60c3de3bc4da045a","file_id":"11381","file_name":"2021_EmboReports_Restivo.pdf","access_level":"open_access","file_size":488583,"date_updated":"2022-05-16T07:07:41Z","content_type":"application/pdf"}],"publisher":"EMBO Press","scopus_import":"1","date_created":"2021-11-14T23:01:24Z","article_type":"original","has_accepted_license":"1","article_number":"e53824","month":"11","oa_version":"Published Version","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","oa":1,"publication_status":"published","publication_identifier":{"eissn":["1469-3178"],"issn":["1469-221X"]},"ddc":["570"],"date_updated":"2023-08-14T11:47:35Z","citation":{"apa":"Restivo, L., Gerlach, B., Tsoory, M., Bikovski, L., Badurek, S., Pitzer, C., … Voikar, V.

These two integrable models exhibit a form of duality, and the essential steps of our investigation can therefore be performed in parallel. In every case, conditionally on all eigenvalues, diagonal overlaps are shown to be distributed as a product of independent random variables with explicit distributions. This enables us to prove that the scaled diagonal overlaps, conditionally on one eigenvalue, converge in distribution to a heavy-tail limit, namely, the inverse of a γ2 distribution. We also provide formulae for the conditional expectation of diagonal and off-diagonal overlaps, either with respect to one eigenvalue, or with respect to the whole spectrum. These results, analogous to what is known for the complex Ginibre ensemble, can be obtained in these cases thanks to integration techniques inspired from a previous work by Forrester & Krishnapur."}],"volume":26,"author":[{"last_name":"Dubach","first_name":"Guillaume","orcid":"0000-0001-6892-8137","id":"D5C6A458-10C4-11EA-ABF4-A4B43DDC885E","full_name":"Dubach, Guillaume"}],"date_created":"2021-11-14T23:01:25Z","project":[{"_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","call_identifier":"H2020"}],"article_type":"original","file":[{"success":1,"content_type":"application/pdf","date_updated":"2021-11-15T10:10:17Z","access_level":"open_access","file_size":735940,"file_name":"2021_ElecJournalProb_Dubach.pdf","file_id":"10288","relation":"main_file","checksum":"1c975afb31460277ce4d22b93538e5f9","creator":"cchlebak","date_created":"2021-11-15T10:10:17Z"}],"publisher":"Institute of Mathematical Statistics","scopus_import":"1"},{"intvolume":"       213","_id":"10290","external_id":{"isi":["000720259500002"]},"doi":"10.1016/j.jsb.2021.107808","department":[{"_id":"FlSc"}],"quality_controlled":"1","acknowledgement":"This research was supported by the Scientific Service Units (SSUs) of IST Austria through resources provided by Scientific Computing (SciComp), the Life Science Facility (LSF), the BioImaging Facility (BIF), and the Electron Microscopy Facility (EMF).

This is particularly true for dynamic extra- and intracellular filamentous assemblies, playing a role in cell motility, cell integrity, cytokinesis, tissue formation and maintenance. For example, genetic manipulation or modulation of actin regulatory proteins frequently manifests in changes of the morphology, dynamics, and ultrastructural architecture of actin filament-rich cell peripheral structures, such as lamellipodia or filopodia. However, the observed ultrastructural effects often remain subtle and require sufficiently large datasets for appropriate quantitative analysis. The acquisition of such large datasets has been enabled by recent advances in high-throughput cryo-electron tomography (cryo-ET) methods. This also necessitates the development of complementary approaches to maximize the extraction of relevant biological information. We have developed a computational toolbox for the semi-automatic quantification of segmented and vectorized filamentous networks from pre-processed cryo-electron tomograms, facilitating the analysis and cross-comparison of multiple experimental conditions. GUI-based components simplify the processing of data and allow users to obtain a large number of ultrastructural parameters describing filamentous assemblies. We demonstrate the feasibility of this workflow by analyzing cryo-ET data of untreated and chemically perturbed branched actin filament networks and that of parallel actin filament arrays. In principle, the computational toolbox presented here is applicable for data analysis comprising any type of filaments in regular (i.e. parallel) or random arrangement. We show that it can ease the identification of key differences between experimental groups and facilitate the in-depth analysis of ultrastructural data in a time-efficient manner."}],"author":[{"id":"38C393BE-F248-11E8-B48F-1D18A9856A87","full_name":"Dimchev, Georgi A","orcid":"0000-0001-8370-6161","first_name":"Georgi A","last_name":"Dimchev"},{"full_name":"Amiri, Behnam","first_name":"Behnam","last_name":"Amiri"},{"last_name":"Fäßler","first_name":"Florian","orcid":"0000-0001-7149-769X","id":"404F5528-F248-11E8-B48F-1D18A9856A87","full_name":"Fäßler, Florian"},{"full_name":"Falcke, Martin","first_name":"Martin","last_name":"Falcke"},{"full_name":"Schur, Florian KM","id":"48AD8942-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-4790-8078","first_name":"Florian KM","last_name":"Schur"}]},{"project":[{"_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications","call_identifier":"FP7","grant_number":"279307"},{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","grant_number":"863818"},{"grant_number":"Z211","call_identifier":"FWF","name":"The Wittgenstein Prize","_id":"25F42A32-B435-11E9-9278-68D0E5697425"},{"_id":"2584A770-B435-11E9-9278-68D0E5697425","name":"Modern Graph Algorithmic Techniques in Formal Verification","grant_number":"P 23499-N23","call_identifier":"FWF"},{"name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","call_identifier":"FWF"}],"date_created":"2021-11-15T17:12:57Z","supervisor":[{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","first_name":"Krishnendu"}],"file":[{"file_size":29703124,"access_level":"closed","file_name":"submission_new.zip","embargo_to":"open_access","content_type":"application/zip","date_updated":"2022-12-20T23:30:08Z","checksum":"86a05b430756ca12ae8107b6e6f3c1e5","relation":"source_file","creator":"lschmid","date_created":"2021-11-18T12:41:46Z","file_id":"10305"},{"relation":"main_file","checksum":"d940af042e94660c6b6a7b4f0b184d47","date_created":"2021-11-18T12:59:15Z","creator":"lschmid","file_id":"10306","access_level":"open_access","file_size":8320985,"file_name":"thesis_new_upload.pdf","content_type":"application/pdf","date_updated":"2022-12-20T23:30:08Z","embargo":"2022-10-18"}],"publisher":"Institute of Science and Technology Austria","ec_funded":1,"year":"2021","language":[{"iso":"eng"}],"day":"17","date_published":"2021-11-17T00:00:00Z","abstract":[{"lang":"eng","text":"Indirect reciprocity in evolutionary game theory is a prominent mechanism for explaining the evolution of cooperation among unrelated individuals. In contrast to direct reciprocity, which is based on individuals meeting repeatedly, and conditionally cooperating by using their own experiences, indirect reciprocity is based on individuals’ reputations. If a player helps another, this increases the helper’s public standing, benefitting them in the future. This lets cooperation in the population emerge without individuals having to meet more than once. While the two modes of reciprocity are intertwined, they are difficult to compare. Thus, they are usually studied in isolation. Direct reciprocity can maintain cooperation with simple strategies, and is robust against noise even when players do not remember more\r\nthan their partner’s last action. Meanwhile, indirect reciprocity requires its successful strategies, or social norms, to be more complex. Exhaustive search previously identified eight such norms, called the “leading eight”, which excel at maintaining cooperation. However, as the first result of this thesis, we show that the leading eight break down once we remove the fundamental assumption that information is synchronized and public, such that everyone agrees on reputations. Once we consider a more realistic scenario of imperfect information, where reputations are private, and individuals occasionally misinterpret or miss observations, the leading eight do not promote cooperation anymore. Instead, minor initial disagreements can proliferate, fragmenting populations into subgroups. In a next step, we consider ways to mitigate this issue. We first explore whether introducing “generosity” can stabilize cooperation when players use the leading eight strategies in noisy environments. This approach of modifying strategies to include probabilistic elements for coping with errors is known to work well in direct reciprocity. However, as we show here, it fails for the more complex norms of indirect reciprocity. Imperfect information still prevents cooperation from evolving. On the other hand, we succeeded to show in this thesis that modifying the leading eight to use “quantitative assessment”, i.e. tracking reputation scores on a scale beyond good and bad, and making overall judgments of others based on a threshold, is highly successful, even when noise increases in the environment. Cooperation can flourish when reputations\r\nare more nuanced, and players have a broader understanding what it means to be “good.” Finally, we present a single theoretical framework that unites the two modes of reciprocity despite their differences. Within this framework, we identify a novel simple and successful strategy for indirect reciprocity, which can cope with noisy environments and has an analogue in direct reciprocity. We can also analyze decision making when different sources of information are available. Our results help highlight that for sustaining cooperation, already the most simple rules of reciprocity can be sufficient."}],"author":[{"orcid":"0000-0002-6978-7329","first_name":"Laura","last_name":"Schmid","id":"38B437DE-F248-11E8-B48F-1D18A9856A87","full_name":"Schmid, Laura"}],"file_date_updated":"2022-12-20T23:30:08Z","department":[{"_id":"GradSch"},{"_id":"KrCh"}],"degree_awarded":"PhD","page":"171","_id":"10293","doi":"10.15479/at:ista:10293","status":"public","type":"dissertation","title":"Evolution of cooperation via (in)direct reciprocity under imperfect information","article_processing_charge":"No","citation":{"mla":"Schmid, Laura. <i>Evolution of Cooperation via (in)Direct Reciprocity under Imperfect Information</i>.

In striking contrast, viscoelastic fluids can exhibit disordered motion even at vanishing inertia. Intermediate between these cases, a state of chaotic motion, “elastoinertial turbulence” (EIT), has been observed in a narrow Reynolds number interval. We here determine the origin of EIT in experiments and show that characteristic EIT structures can be detected across an unexpectedly wide range of parameters. Close to onset, a pattern of chevron-shaped streaks emerges in qualitative agreement with linear and weakly nonlinear theory. However, in experiments, the dynamics remain weakly chaotic, and the instability can be traced to far lower Reynolds numbers than permitted by theory. For increasing inertia, the flow undergoes a transformation to a wall mode composed of inclined near-wall streaks and shear layers. This mode persists to what is known as the “maximum drag reduction limit,” and overall EIT is found to dominate viscoelastic flows across more than three orders of magnitude in Reynolds number.","lang":"eng"}],"volume":118,"date_published":"2021-11-03T00:00:00Z","author":[{"full_name":"Choueiri, George H","id":"448BD5BC-F248-11E8-B48F-1D18A9856A87","first_name":"George H","last_name":"Choueiri"},{"last_name":"Lopez Alonso","first_name":"Jose M","orcid":"0000-0002-0384-2022","full_name":"Lopez Alonso, Jose M","id":"40770848-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Atul","last_name":"Varshney","orcid":"0000-0002-3072-5999","id":"2A2006B2-F248-11E8-B48F-1D18A9856A87","full_name":"Varshney, Atul"},{"full_name":"Sankar, Sarath","last_name":"Sankar","first_name":"Sarath"},{"full_name":"Hof, Björn","id":"3A374330-F248-11E8-B48F-1D18A9856A87","last_name":"Hof","first_name":"Björn","orcid":"0000-0003-2057-2754"}],"day":"03","language":[{"iso":"eng"}],"year":"2021","publication":"Proceedings of the National Academy of Sciences","keyword":["multidisciplinary","elastoinertial turbulence","viscoelastic flows","elastic instability","drag reduction"],"publisher":"National Academy of Sciences","main_file_link":[{"url":"https://arxiv.org/abs/2103.00023","open_access":"1"}],"pmid":1,"scopus_import":"1","project":[{"call_identifier":"FWF","grant_number":"I04188","_id":"238B8092-32DE-11EA-91FC-C7463DDC885E","name":"Instabilities in pulsating pipe flow of Newtonian and complex fluids"}],"article_type":"original","date_created":"2021-11-17T13:24:24Z"}]
