The singular value statistics of all three ensembles is shown to be determinantal and we derive double contour integral representations for their respective kernels. Three different kernels are found in the limit of infinite matrix dimension at the origin of the spectrum. They depend on finite rank perturbations of the correlation and coupling matrices and are shown to be integrable. The first kernel (I) is found for two independent matrices from the second, and two weakly coupled matrices from the third ensemble. It generalises the Meijer G-kernel for two independent and uncorrelated matrices. The third kernel (III) is obtained for the generalised Wishart ensemble and for two strongly coupled matrices.

Here we present the first genomic view of a reciprocal translocation that causes two physically unconnected pairs of chromosomes to be coinherited as sex chromosomes. In a population of the common frog (Rana temporaria), both pairs of X and Y chromosomes show extensive sequence differentiation, but not degeneration of the Y chromosomes. A new method based on gene trees shows both chromosomes are sex‐linked. Furthermore, the gene trees from the two Y chromosomes have identical topologies, showing they have been coinherited since the reciprocal translocation occurred. Reciprocal translocations can thus reshape sex linkage on a much greater scale compared with inversions, the type of rearrangement that is much better known in sex chromosome evolution, and they can greatly amplify the power of sexually antagonistic selection to drive genomic rearrangement. Two more populations show evidence of other rearrangements, suggesting that this species has unprecedented structural polymorphism in its sex chromosomes.","lang":"eng"}],"_id":"7421","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","intvolume":" 28","status":"public","title":"A reciprocal translocation radically reshapes sex‐linked inheritance in the common frog","oa_version":"None","article_processing_charge":"No","day":"01","citation":{"short":"M.A. Toups, N.

Isolated SVs from neurons that have been genetically engineered, e.g. to introduce genetically encoded indicators, are not readily available but would permit new insights into SV structure and function. Furthermore, it is unclear if cultured neurons can provide sufficient starting material for SV isolation procedures.\r\n\r\nNew method\r\nHere, we demonstrate an efficient ex vivo procedure to obtain functional SVs from cultured rat cortical neurons after genetic engineering with a lentivirus.\r\n\r\nResults\r\nWe show that ∼108 plated cortical neurons allow isolation of suitable SV amounts for functional analysis and imaging. We found that SVs isolated from cultured neurons have neurotransmitter uptake comparable to that of SVs isolated from intact cortex. Using total internal reflection fluorescence (TIRF) microscopy, we visualized an exogenous SV-targeted marker protein and demonstrated the high efficiency of SV modification.\r\n\r\nComparison with existing methods\r\nObtaining SVs from genetically engineered neurons currently generally requires the availability of transgenic animals, which is constrained by technical (e.g. cost and time) and biological (e.g. developmental defects and lethality) limitations.\r\n\r\nConclusions\r\nThese results demonstrate the modification and isolation of functional SVs using cultured neurons and viral transduction.

At the same time, recent work exhibits the impressive tolerance of machine learning algorithms to errors or noise arising from relaxed communication or synchronization. In this paper, we connect these two trends, and consider the following question: Can we design machine learning systems that are tolerant to network unreliability during training? With this motivation, we focus on a theoretical problem of independent interest-given a standard distributed parameter server architecture, if every communication between the worker and the server has a non-zero probability p of being dropped, does there exist an algorithm that still converges, and at what speed? The technical contribution of this paper is a novel theoretical analysis proving that distributed learning over unreliable network can achieve comparable convergence rate to centralized or distributed learning over reliable networks. Further, we prove that the influence of the packet drop rate diminishes with the growth of the number of parameter servers. We map this theoretical result onto a real-world scenario, training deep neural networks over an unreliable network layer, and conduct network simulation to validate the system improvement by allowing the networks to be unreliable."}],"type":"conference","oa_version":"Preprint","title":"Distributed learning over unreliable networks","status":"public","_id":"7437","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1"},{"date_published":"2019-10-31T00:00:00Z","article_type":"original","page":"1583-1602","publication":"SIAM Journal on Computing","citation":{"mla":"Achlioptas, Dimitris, et al. “A Local Lemma for Focused Stochastical Algorithms.” SIAM Journal on Computing, vol. 48, no. 5, SIAM, 2019, pp. 1583–602, doi:10.1137/16m109332x.","short":"D.

These algorithms search a state space by repeatedly selecting some constraint that is violated in the current state and moving to a random nearby state that addresses the violation, while (we hope) not introducing many new violations. An important class of focused local search algorithms with provable performance guarantees has recently arisen from algorithmizations of the Lovász local lemma (LLL), a nonconstructive tool for proving the existence of satisfying states by introducing a background measure on the state space. While powerful, the state transitions of algorithms in this class must be, in a precise sense, perfectly compatible with the background measure. In many applications this is a very restrictive requirement, and one needs to step outside the class. Here we introduce the notion of measure distortion and develop a framework for analyzing arbitrary focused stochastic local search algorithms, recovering LLL algorithmizations as the special case of no distortion. Our framework takes as input an arbitrary algorithm of such type and an arbitrary probability measure and shows how to use the measure as a yardstick of algorithmic progress, even for algorithms designed independently of the measure."}],"issue":"5","type":"journal_article","language":[{"iso":"eng"}],"doi":"10.1137/16m109332x","quality_controlled":"1","isi":1,"project":[{"_id":"25FBA906-B435-11E9-9278-68D0E5697425","grant_number":"616160","call_identifier":"FP7","name":"Discrete Optimization in Computer Vision: Theory and Practice"}],"oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1809.01537"}],"external_id":{"isi":["000493900200005"],"arxiv":["1809.01537"]},"month":"10","publication_identifier":{"eissn":["1095-7111"],"issn":["0097-5397"]},"date_created":"2020-01-30T09:27:32Z","date_updated":"2023-09-06T15:25:29Z","volume":48,"author":[{"full_name":"Achlioptas, Dimitris","first_name":"Dimitris","last_name":"Achlioptas"},{"full_name":"Iliopoulos, Fotis","last_name":"Iliopoulos","first_name":"Fotis"},{"full_name":"Kolmogorov, Vladimir","id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","last_name":"Kolmogorov","first_name":"Vladimir"}],"publication_status":"published","department":[{"_id":"VlKo"}],"publisher":"SIAM","year":"2019","ec_funded":1},{"month":"11","publication_identifier":{"eissn":["1557-7368"],"issn":["0730-0301"]},"doi":"10.1145/3355089.3356565","language":[{"iso":"eng"}],"external_id":{"isi":["000498397300001"]},"isi":1,"quality_controlled":"1","article_number":"151","author":[{"last_name":"Karlík","first_name":"Ondřej","full_name":"Karlík, Ondřej"},{"last_name":"Šik","first_name":"Martin","full_name":"Šik, Martin"},{"full_name":"Vévoda, Petr","first_name":"Petr","last_name":"Vévoda"},{"id":"486A5A46-F248-11E8-B48F-1D18A9856A87","first_name":"Tomas","last_name":"Skrivan","full_name":"Skrivan, Tomas"},{"full_name":"Křivánek, Jaroslav","last_name":"Křivánek","first_name":"Jaroslav"}],"date_created":"2020-01-30T10:19:43Z","date_updated":"2023-09-06T15:22:23Z","volume":38,"year":"2019","publication_status":"published","department":[{"_id":"ChWo"}],"publisher":"ACM","day":"01","article_processing_charge":"No","scopus_import":"1","date_published":"2019-11-01T00:00:00Z","publication":"ACM Transactions on Graphics","citation":{"chicago":"Karlík, Ondřej, Martin Šik, Petr Vévoda, Tomas Skrivan, and Jaroslav Křivánek. “MIS Compensation: Optimizing Sampling Techniques in Multiple Importance Sampling.” ACM Transactions on Graphics.

We show that by generalizing the MIS framework, variance can be substantially reduced. Specifically, we optimize one of the combined sampling techniques so as to decrease the overall variance of the resulting MIS estimator. We apply the approach to the computation of direct illumination due to an HDR environment map and to the computation of global illumination using a path guiding algorithm. The implementation can be as simple as subtracting a constant value from the tabulated sampling density done entirely in a preprocessing step. This produces a consistent noise reduction in all our tests with no negative influence on run time, no artifacts or bias, and no failure cases.","lang":"eng"}],"issue":"6","type":"journal_article","oa_version":"None","_id":"7418","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","title":"MIS compensation: Optimizing sampling techniques in multiple importance sampling","status":"public","intvolume":" 38"},{"oa_version":"Preprint","status":"public","title":"Bogoliubov theory in the Gross–Pitaevskii limit","intvolume":" 222","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"7413","abstract":[{"lang":"eng","text":"We consider Bose gases consisting of N particles trapped in a box with volume one and interacting through a repulsive potential with scattering length of order N−1 (Gross–Pitaevskii regime).

Parallel divergence often occurs in heterogeneous environments with different kinds of environmental gradients in different locations, but the genomic basis underlying this process is unknown. We investigated the genomics of rapid parallel adaptation in the marine snail Littorina saxatilis in response to two independent environmental axes (crab-predation versus wave-action and low-shore versus high-shore). Using pooled whole-genome resequencing, we show that sharing of genomic regions of high differentiation between environments is generally low but increases at smaller spatial scales. We identify different shared genomic regions of divergence for each environmental axis and show that most of these regions overlap with candidate chromosomal inversions. Several inversion regions are divergent and polymorphic across many localities. We argue that chromosomal inversions could store shared variation that fuels rapid parallel adaptation to heterogeneous environments, possibly as balanced polymorphism shared by adaptive gene flow."}],"issue":"12","quality_controlled":"1","isi":1,"project":[{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"},{"grant_number":"797747","_id":"265B41B8-B435-11E9-9278-68D0E5697425","name":"Theoretical and empirical approaches to understanding Parallel Adaptation","call_identifier":"H2020"}],"tmp":{"name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png","short":"CC BY-NC (4.0)"},"oa":1,"external_id":{"pmid":["31840052"],"isi":["000505069600008"]},"language":[{"iso":"eng"}],"doi":"10.1126/sciadv.aav9963","month":"12","publication_identifier":{"issn":["2375-2548"]},"publication_status":"published","publisher":"AAAS","department":[{"_id":"NiBa"}],"year":"2019","pmid":1,"date_created":"2020-01-29T15:58:27Z","date_updated":"2023-09-06T15:35:56Z","volume":5,"author":[{"full_name":"Morales, Hernán E.","first_name":"Hernán E.","last_name":"Morales"},{"full_name":"Faria, Rui","first_name":"Rui","last_name":"Faria"},{"last_name":"Johannesson","first_name":"Kerstin","full_name":"Johannesson, Kerstin"},{"last_name":"Larsson","first_name":"Tomas","full_name":"Larsson, Tomas"},{"first_name":"Marina","last_name":"Panova","full_name":"Panova, Marina"},{"last_name":"Westram","first_name":"Anja M","orcid":"0000-0003-1050-4969","id":"3C147470-F248-11E8-B48F-1D18A9856A87","full_name":"Westram, Anja M"},{"last_name":"Butlin","first_name":"Roger K.","full_name":"Butlin, Roger K."}],"article_number":"eaav9963","license":"https://creativecommons.org/licenses/by-nc/4.0/","file_date_updated":"2020-07-14T12:47:57Z","ec_funded":1},{"month":"09","publication_identifier":{"issn":["0022-1120"],"eissn":["1469-7645"]},"doi":"10.1017/jfm.2019.486","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1808.04080","open_access":"1"}],"oa":1,"external_id":{"arxiv":["1808.04080"],"isi":["000475349900001"]},"isi":1,"quality_controlled":"1","author":[{"full_name":"Lopez Alonso, Jose M","last_name":"Lopez Alonso","first_name":"Jose M","orcid":"0000-0002-0384-2022","id":"40770848-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Choueiri, George H","first_name":"George H","last_name":"Choueiri","id":"448BD5BC-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Hof, Björn","first_name":"Björn","last_name":"Hof","id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754"}],"date_created":"2020-01-29T16:05:19Z","date_updated":"2023-09-06T15:36:36Z","volume":874,"year":"2019","publication_status":"published","publisher":"CUP","department":[{"_id":"BjHo"}],"day":"10","article_processing_charge":"No","scopus_import":"1","date_published":"2019-09-10T00:00:00Z","publication":"Journal of Fluid Mechanics","citation":{"chicago":"Lopez Alonso, Jose M, George H Choueiri, and Björn Hof. “Dynamics of Viscoelastic Pipe Flow at Low Reynolds Numbers in the Maximum Drag Reduction Limit.” Journal of Fluid Mechanics.

Until recently, the consensus was that,in this limit, flows are in a marginal state where only a minimal level of turbulence activ-ity persists. Observations in direct numerical simulations using minimal sized channelsappeared to support this view and reported long “hibernation” periods where turbu-lence is marginalized. In simulations of pipe flow we find that, indeed, with increasingWeissenberg number (Wi), turbulence expresses long periods of hibernation if the domainsize is small. However, with increasing pipe length, the temporal hibernation continuouslyalters to spatio-temporal intermittency and here the flow consists of turbulent puffs sur-rounded by laminar flow. Moreover, upon an increase in Wi, the flow fully relaminarises,in agreement with recent experiments. At even larger Wi, a different instability is en-countered causing a drag increase towards MDR. Our findings hence link earlier minimalflow unit simulations with recent experiments and confirm that the addition of polymersinitially suppresses Newtonian turbulence and leads to a reverse transition. The MDRstate on the other hand results from a separate instability and the underlying dynamicscorresponds to the recently proposed state of elasto-inertial-turbulence (EIT).","lang":"eng"}],"type":"journal_article","oa_version":"Preprint","_id":"7397","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","title":"Dynamics of viscoelastic pipe flow at low Reynolds numbers in the maximum drag reduction limit","status":"public","intvolume":" 874"},{"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"},"oa":1,"external_id":{"arxiv":["1709.09380"],"isi":["000494042900008"]},"project":[{"call_identifier":"H2020","name":"Alpha Shape Theory Extended","_id":"266A2E9E-B435-11E9-9278-68D0E5697425","grant_number":"788183"},{"call_identifier":"FWF","name":"Persistence and stability of geometric complexes","grant_number":"I02979-N35","_id":"2561EBF4-B435-11E9-9278-68D0E5697425"},{"name":"IST Austria Open Access Fund","_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854"}],"quality_controlled":"1","isi":1,"doi":"10.1007/s00454-018-0049-2","language":[{"iso":"eng"}],"publication_identifier":{"issn":["01795376"],"eissn":["14320444"]},"month":"12","year":"2019","department":[{"_id":"HeEd"}],"publisher":"Springer","publication_status":"published","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"6287"}]},"author":[{"orcid":"0000-0002-9823-6833","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","last_name":"Edelsbrunner","first_name":"Herbert","full_name":"Edelsbrunner, Herbert"},{"first_name":"Anton","last_name":"Nikitenko","id":"3E4FF1BA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0659-3201","full_name":"Nikitenko, Anton"}],"volume":62,"date_updated":"2023-09-07T12:07:12Z","date_created":"2018-12-16T22:59:20Z","ec_funded":1,"file_date_updated":"2020-07-14T12:47:10Z","license":"https://creativecommons.org/licenses/by/4.0/","citation":{"ama":"Edelsbrunner H, Nikitenko A.

Here, when subjected to strong enough perturbations, the flow becomes turbulent in spite of the laminar base flow being linearly stable. The nature of this instability has puzzled the scientific community for decades. At onset, turbulence appears in localized patches and flows are spatio-temporally intermittent. In pipe flow the localized turbulent structures are referred to as puffs and in planar flows like plane Couette and channel flow, patches arise in the form of localized oblique bands. In this thesis, we study the onset of turbulence in channel flow in direct numerical simulations from a dynamical system theory perspective, as well as by performing experiments in a large aspect ratio channel.\r\n\r\nThe aim of the experimental work is to determine the critical Reynolds number where turbulence first becomes sustained. Recently, the onset of turbulence has been described in analogy to absorbing state phase transition (i.e. directed percolation). In particular, it has been shown that the critical point can be estimated from the competition between spreading and decay processes. Here, by performing experiments, we identify the mechanisms underlying turbulence proliferation in channel flow and find the critical Reynolds number, above which turbulence becomes sustained. Above the critical point, the continuous growth at the tip of the stripes outweighs the stochastic shedding of turbulent patches at the tail and the stripes expand. For growing stripes, the probability to decay decreases while the probability of stripe splitting increases. Consequently, and unlike for the puffs in pipe flow, neither of these two processes is time-independent i.e. memoryless. Coupling between stripe expansion and creation of new stripes via splitting leads to a significantly lower critical point ($Re_c=670+/-10$) than most earlier studies suggest. \r\n\r\nWhile the above approach sheds light on how turbulence first becomes sustained, it provides no insight into the origin of the stripes themselves. In the numerical part of the thesis we investigate how turbulent stripes form from invariant solutions of the Navier-Stokes equations. The origin of these turbulent stripes can be identified by applying concepts from the dynamical system theory. In doing so, we identify the exact coherent structures underlying stripes and their bifurcations and how they give rise to the turbulent attractor in phase space. We first report a family of localized nonlinear traveling wave solutions of the Navier-Stokes equations in channel flow. These solutions show structural similarities with turbulent stripes in experiments like obliqueness, quasi-streamwise streaks and vortices, etc. A parametric study of these traveling wave solution is performed, with parameters like Reynolds number, stripe tilt angle and domain size, including the stability of the solutions. These solutions emerge through saddle-node bifurcations and form a phase space skeleton for the turbulent stripes observed in the experiments. The lower branches of these TW solutions at different tilt angles undergo Hopf bifurcation and new solutions branches of relative periodic orbits emerge. These RPO solutions do not belong to the same family and therefore the routes to chaos for different angles are different. \r\n\r\nIn shear flows, turbulence at onset is transient in nature. Consequently,turbulence can not be tracked to lower Reynolds numbers, where the dynamics may simplify. Before this happens, turbulence becomes short-lived and laminarizes. In the last part of the thesis, we show that using numerical simulations we can continue turbulent stripes in channel flow past the 'relaminarization barrier' all the way to their origin. Here, turbulent stripe dynamics simplifies and the fluctuations are no longer stochastic and the stripe settles down to a relative periodic orbit. This relative periodic orbit originates from the aforementioned traveling wave solutions. Starting from the relative periodic orbit, a small increase in speed i.e. Reynolds number gives rise to chaos and the attractor dimension sharply increases in contrast to the classical transition scenario where the instabilities affect the flow globally and give rise to much more gradual route to turbulence.","lang":"eng"}],"page":"138","citation":{"mla":"Paranjape, Chaitanya S.

A pressing data-analysis challenge has thus been to efficiently estimate the amount of information that these dynamics convey from experimental data. Here we develop and evaluate decoding-based estimation methods to lower bound the mutual information about a finite set of inputs, encoded in single-cell high-dimensional time series data. For biological reaction networks governed by the chemical Master equation, we derive model-based information approximations and analytical upper bounds, against which we benchmark our proposed model-free decoding estimators. In contrast to the frequently-used k-nearest-neighbor estimator, decoding-based estimators robustly extract a large fraction of the available information from high-dimensional trajectories with a realistic number of data samples. We apply these estimators to previously published data on Erk and Ca2+ signaling in mammalian cells and to yeast stress-response, and find that substantial amount of information about environmental state can be encoded by non-trivial response statistics even in stationary signals. We argue that these single-cell, decoding-based information estimates, rather than the commonly-used tests for significant differences between selected population response statistics, provide a proper and unbiased measure for the performance of biological signaling networks.","lang":"eng"}],"issue":"9","type":"journal_article"},{"department":[{"_id":"JiFr"}],"publisher":"Springer Nature","publication_status":"published","year":"2019","volume":15,"date_created":"2019-05-05T21:59:11Z","date_updated":"2023-09-07T12:54:35Z","related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"7172"}]},"author":[{"first_name":"Wim","last_name":"Dejonghe","full_name":"Dejonghe, Wim"},{"last_name":"Sharma","first_name":"Isha","full_name":"Sharma, Isha"},{"first_name":"Bram","last_name":"Denoo","full_name":"Denoo, Bram"},{"full_name":"De Munck, Steven","first_name":"Steven","last_name":"De Munck"},{"first_name":"Qing","last_name":"Lu","full_name":"Lu, Qing"},{"full_name":"Mishev, Kiril","last_name":"Mishev","first_name":"Kiril"},{"full_name":"Bulut, Haydar","last_name":"Bulut","first_name":"Haydar"},{"first_name":"Evelien","last_name":"Mylle","full_name":"Mylle, Evelien"},{"full_name":"De Rycke, Riet","first_name":"Riet","last_name":"De Rycke"},{"id":"3407EB18-F248-11E8-B48F-1D18A9856A87","first_name":"Mina K","last_name":"Vasileva","full_name":"Vasileva, Mina K"},{"full_name":"Savatin, Daniel V.","first_name":"Daniel V.","last_name":"Savatin"},{"last_name":"Nerinckx","first_name":"Wim","full_name":"Nerinckx, Wim"},{"full_name":"Staes, An","first_name":"An","last_name":"Staes"},{"full_name":"Drozdzecki, Andrzej","last_name":"Drozdzecki","first_name":"Andrzej"},{"full_name":"Audenaert, Dominique","last_name":"Audenaert","first_name":"Dominique"},{"first_name":"Klaas","last_name":"Yperman","full_name":"Yperman, Klaas"},{"full_name":"Madder, Annemieke","first_name":"Annemieke","last_name":"Madder"},{"id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596","first_name":"Jiří","last_name":"Friml","full_name":"Friml, Jiří"},{"full_name":"Van Damme, Daniël","last_name":"Van Damme","first_name":"Daniël"},{"first_name":"Kris","last_name":"Gevaert","full_name":"Gevaert, Kris"},{"first_name":"Volker","last_name":"Haucke","full_name":"Haucke, Volker"},{"last_name":"Savvides","first_name":"Savvas N.","full_name":"Savvides, Savvas N."},{"full_name":"Winne, Johan","last_name":"Winne","first_name":"Johan"},{"first_name":"Eugenia","last_name":"Russinova","full_name":"Russinova, Eugenia"}],"publication_identifier":{"eissn":["15524469"],"issn":["15524450"]},"month":"06","quality_controlled":"1","isi":1,"external_id":{"isi":["000468195600018"]},"language":[{"iso":"eng"}],"doi":"10.1038/s41589-019-0262-1","type":"journal_article","issue":"6","abstract":[{"text":"Clathrin-mediated endocytosis (CME) is a highly conserved and essential cellular process in eukaryotic cells, but its dynamic and vital nature makes it challenging to study using classical genetics tools.

While the molecular signaling cascades are increasingly well\r\ndescribed, the mechanical signals affecting tissue shape changes have only recently been\r\nstudied in greater detail. To gain more insight into the mechanochemical and biophysical\r\nbasis of an epithelial spreading process (epiboly) in early zebrafish development, we studied\r\ncell-cell junction formation and actomyosin network dynamics at the boundary between\r\nsurface layer epithelial cells (EVL) and the yolk syncytial layer (YSL). During zebrafish epiboly,\r\nthe cell mass sitting on top of the yolk cell spreads to engulf the yolk cell by the end of\r\ngastrulation. It has been previously shown that an actomyosin ring residing within the YSL\r\npulls on the EVL tissue through a cable-constriction and a flow-friction motor, thereby\r\ndragging the tissue vegetal wards. Pulling forces are likely transmitted from the YSL\r\nactomyosin ring to EVL cells; however, the nature and formation of the junctional structure\r\nmediating this process has not been well described so far. Therefore, our main aim was to\r\ndetermine the nature, dynamics and potential function of the EVL-YSL junction during this\r\nepithelial tissue spreading. Specifically, we show that the EVL-YSL junction is a\r\nmechanosensitive structure, predominantly made of tight junction (TJ) proteins. The process\r\nof TJ mechanosensation depends on the retrograde flow of non-junctional, phase-separated\r\nZonula Occludens-1 (ZO-1) protein clusters towards the EVL-YSL boundary. Interestingly, we\r\ncould demonstrate that ZO-1 is present in a non-junctional pool on the surface of the yolk\r\ncell, and ZO-1 undergoes a phase separation process that likely renders the protein\r\nresponsive to flows. These flows are directed towards the junction and mediate proper\r\ntension-dependent recruitment of ZO-1. Upon reaching the EVL-YSL junction ZO-1 gets\r\nincorporated into the junctional pool mediated through its direct actin-binding domain.\r\nWhen the non-junctional pool and/or ZO-1 direct actin binding is absent, TJs fail in their\r\nproper mechanosensitive responses resulting in slower tissue spreading. We could further\r\ndemonstrate that depletion of ZO proteins within the YSL results in diminished actomyosin\r\nring formation. This suggests that a mechanochemical feedback loop is at work during\r\nzebrafish epiboly: ZO proteins help in proper actomyosin ring formation and actomyosin\r\ncontractility and flows positively influence ZO-1 junctional recruitment. Finally, such a\r\nmesoscale polarization process mediated through the flow of phase-separated protein\r\nclusters might have implications for other processes such as immunological synapse\r\nformation, C. elegans zygote polarization and wound healing."}],"type":"dissertation","alternative_title":["ISTA Thesis"],"oa_version":"Published Version","file":[{"file_name":"DocumentSourceFiles.zip","access_level":"closed","creator":"cschwayer","content_type":"application/zip","file_size":19431292,"file_id":"7194","relation":"source_file","date_created":"2019-12-19T15:18:11Z","date_updated":"2020-07-14T12:47:52Z","checksum":"585583c1c875c5d9525703a539668a7c"},{"access_level":"open_access","file_name":"Thesis_CS_final.pdf","creator":"cschwayer","content_type":"application/pdf","file_size":19226428,"file_id":"7195","relation":"main_file","checksum":"9b9b24351514948d27cec659e632e2cd","date_created":"2019-12-19T15:19:21Z","date_updated":"2020-07-14T12:47:52Z"}],"_id":"7186","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","title":"Mechanosensation of tight junctions depends on ZO-1 phase separation and flow","ddc":["570"],"status":"public","has_accepted_license":"1","article_processing_charge":"No","day":"16","date_published":"2019-12-16T00:00:00Z","citation":{"chicago":"Schwayer, Cornelia. “Mechanosensation of Tight Junctions Depends on ZO-1 Phase Separation and Flow.” Institute of Science and Technology Austria, 2019. https://doi.org/10.15479/AT:ISTA:7186.","short":"C.

It is well known that there is no algorithm to decide whether the fundamental group π1(X) of a given finite simplicial complex X is trivial. On the other hand, there are several algorithms that, given a finite simplicial complex X that is simply connected (i.e., with π1(X) trivial), compute the higher homotopy group πd(X) for any given d ≥ 2.\r\nHowever, these algorithms come with a caveat: They compute the isomorphism type of πd(X), d ≥ 2 as an abstract finitely generated abelian group given by generators and relations, but they work with very implicit representations of the elements of πd(X). We present an algorithm that, given a simply connected space X, computes πd(X) and represents its elements as simplicial maps from suitable triangulations of the d-sphere Sd to X. For fixed d, the algorithm runs in time exponential in size(X), the number of simplices of X. Moreover, we prove that this is optimal: For every fixed d ≥ 2,\r\nwe construct a family of simply connected spaces X such that for any simplicial map representing a generator of πd(X), the size of the triangulation of S d on which the map is defined, is exponential in size(X).\r\nIn the second part of the thesis, we prove that the following question is algorithmically undecidable for d < ⌊3(k+1)/2⌋, k ≥ 5 and (k, d) ̸= (5, 7), which covers essentially everything outside the meta-stable range: Given a finite simplicial complex K of dimension k, decide whether there exists a piecewise-linear (i.e., linear on an arbitrarily fine subdivision of K) embedding f : K ↪→ Rd of K into a d-dimensional Euclidean space.","lang":"eng"}],"alternative_title":["ISTA Thesis"],"type":"dissertation","oa_version":"Published Version","file":[{"date_created":"2019-08-07T13:02:50Z","date_updated":"2020-07-14T12:47:37Z","checksum":"3231e7cbfca3b5687366f84f0a57a0c0","file_id":"6771","relation":"main_file","creator":"szhechev","file_size":1464227,"content_type":"application/pdf","file_name":"Stephan_Zhechev_thesis.pdf","access_level":"open_access"},{"content_type":"application/octet-stream","file_size":303988,"creator":"szhechev","file_name":"Stephan_Zhechev_thesis.tex","access_level":"closed","date_updated":"2020-07-14T12:47:37Z","date_created":"2019-08-07T13:03:22Z","checksum":"85d65eb27b4377a9e332ee37a70f08b6","relation":"source_file","file_id":"6772"},{"file_id":"6773","relation":"supplementary_material","checksum":"86b374d264ca2dd53e712728e253ee75","date_updated":"2020-07-14T12:47:37Z","date_created":"2019-08-07T13:03:34Z","access_level":"closed","file_name":"supplementary_material.zip","creator":"szhechev","file_size":1087004,"content_type":"application/zip"}],"status":"public","ddc":["514"],"title":"Algorithmic aspects of homotopy theory and embeddability","_id":"6681","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","has_accepted_license":"1","article_processing_charge":"No","day":"08","date_published":"2019-08-08T00:00:00Z","page":"104","citation":{"mla":"Zhechev, Stephan Y.
