Unexpectedly,we found that the antagonist regulators of DNA repli-cation, GemC1 and Geminin, can tune the proportionof neural stem cells and ependymal cells.

How these cells are molecularly temporally patterned is poorly understood. We used single-cell RNA sequencing at high temporal resolution to trace the lineage of the molecular identities of successive generations of apical progenitors (APs) and their daughter neurons in mouse embryos. We identified a core set of evolutionarily conserved, temporally patterned genes that drive APs from internally driven to more exteroceptive states. We found that the Polycomb repressor complex 2 (PRC2) epigenetically regulates AP temporal progression. Embryonic age–dependent AP molecular states are transmitted to their progeny as successive ground states, onto which essentially conserved early postmitotic differentiation programs are applied, and are complemented by later-occurring environment-dependent signals. Thus, epigenetically regulated temporal molecular birthmarks present in progenitors act in their postmitotic progeny to seed adult neuronal diversity.","lang":"eng"}],"scopus_import":"1","date_updated":"2023-09-05T11:51:09Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","language":[{"iso":"eng"}],"status":"public","author":[{"full_name":"Telley, L","last_name":"Telley","first_name":"L"},{"first_name":"G","full_name":"Agirman, G","last_name":"Agirman"},{"last_name":"Prados","full_name":"Prados, J","first_name":"J"},{"orcid":"0000-0002-3183-8207","full_name":"Amberg, Nicole","last_name":"Amberg","first_name":"Nicole","id":"4CD6AAC6-F248-11E8-B48F-1D18A9856A87"},{"first_name":"S","last_name":"Fièvre","full_name":"Fièvre, S"},{"last_name":"Oberst","full_name":"Oberst, P","first_name":"P"},{"last_name":"Bartolini","full_name":"Bartolini, G","first_name":"G"},{"first_name":"I","last_name":"Vitali","full_name":"Vitali, I"},{"first_name":"C","last_name":"Cadilhac","full_name":"Cadilhac, C"},{"id":"37B36620-F248-11E8-B48F-1D18A9856A87","first_name":"Simon","last_name":"Hippenmeyer","full_name":"Hippenmeyer, Simon","orcid":"0000-0003-2279-1061"},{"first_name":"L","full_name":"Nguyen, L","last_name":"Nguyen"},{"last_name":"Dayer","full_name":"Dayer, A","first_name":"A"},{"last_name":"Jabaudon","full_name":"Jabaudon, D","first_name":"D"}],"citation":{"mla":"Telley, L., et al. “Temporal Patterning of Apical Progenitors and Their Daughter Neurons in the Developing Neocortex.” Science, vol. 364, no. 6440, eaav2522, AAAS, 2019, doi:10.1126/science.aav2522.","chicago":"Telley, L, G Agirman, J Prados, Nicole Amberg, S Fièvre, P Oberst, G Bartolini, et al. “Temporal Patterning of Apical Progenitors and Their Daughter Neurons in the Developing Neocortex.” Science.

At each time point,it reads the plant’s state and issues commands with the goal that the plant oper-ates optimally. Constructing optimal controllers is a fundamental and challengingproblem. Machine learning techniques have recently been successfully applied totrain controllers, yet they have limitations. Learned controllers are monolithic andhard to reason about. In particular, it is difficult to add features without retraining,to guarantee any level of performance, and to achieve acceptable performancewhen encountering untrained scenarios. These limitations can be addressed bydeploying quantitative run-timeshieldsthat serve as a proxy for the controller.At each time point, the shield reads the command issued by the controller andmay choose to alter it before passing it on to the plant. We show how optimalshields that interfere as little as possible while guaranteeing a desired level ofcontroller performance, can be generated systematically and automatically usingreactive synthesis. First, we abstract the plant by building a stochastic model.Second, we consider the learned controller to be a black box. Third, we mea-surecontroller performanceandshield interferenceby two quantitative run-timemeasures that are formally defined using weighted automata. Then, the problemof constructing a shield that guarantees maximal performance with minimal inter-ference is the problem of finding an optimal strategy in a stochastic2-player game“controller versus shield” played on the abstract state space of the plant with aquantitative objective obtained from combining the performance and interferencemeasures. We illustrate the effectiveness of our approach by automatically con-structing lightweight shields for learned traffic-light controllers in various roadnetworks. The shields we generate avoid liveness bugs, improve controller per-formance in untrained and changing traffic situations, and add features to learnedcontrollers, such as giving priority to emergency vehicles.","lang":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"date_updated":"2023-08-25T10:33:27Z","author":[{"id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","first_name":"Guy","full_name":"Avni, Guy","last_name":"Avni","orcid":"0000-0001-5588-8287"},{"full_name":"Bloem, Roderick","last_name":"Bloem","first_name":"Roderick"},{"first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee"},{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A","orcid":"0000−0002−2985−7724","last_name":"Henzinger","full_name":"Henzinger, Thomas A"},{"full_name":"Konighofer, Bettina","last_name":"Konighofer","first_name":"Bettina"},{"first_name":"Stefan","last_name":"Pranger","full_name":"Pranger, Stefan"}],"status":"public","_id":"6462","publication_status":"published","external_id":{"isi":["000491468000036"]},"alternative_title":["LNCS"],"ddc":["000"],"file":[{"file_name":"2019_CAV_Avni.pdf","file_id":"6816","creator":"dernst","relation":"main_file","access_level":"open_access","content_type":"application/pdf","date_updated":"2020-07-14T12:47:31Z","checksum":"c231579f2485c6fd4df17c9443a4d80b","file_size":659766,"date_created":"2019-08-14T09:35:24Z"}],"oa_version":"Published Version","type":"conference","publisher":"Springer","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"year":"2019","month":"07","project":[{"grant_number":"M02369","_id":"264B3912-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Formal Methods meets Algorithmic Game Theory"},{"grant_number":"Z211","name":"The Wittgenstein Prize","call_identifier":"FWF","_id":"25F42A32-B435-11E9-9278-68D0E5697425"},{"grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425","name":"Rigorous Systems Engineering","call_identifier":"FWF"}],"isi":1,"publication_identifier":{"issn":["0302-9743"],"isbn":["9783030255398"]}},{"day":"01","publication":"Nature Communications","volume":10,"date_published":"2019-05-01T00:00:00Z","intvolume":" 10","has_accepted_license":"1","file_date_updated":"2020-07-14T12:47:31Z","doi":"10.1038/s41467-019-09974-5","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"},"article_processing_charge":"No","oa":1,"article_number":"2013","quality_controlled":"1","date_created":"2019-05-19T21:59:14Z","citation":{"chicago":"Chassin, Hélène, Marius Müller, Marcel Tigges, Leo Scheller, Moritz Lang, and Martin Fussenegger. “A Modular Degron Library for Synthetic Circuits in Mammalian Cells.” Nature Communications.

Here we develop a versatile, easy-to-handle library of destabilizing tags (degrons) for the precise regulation of protein expression profiles in mammalian cells by modulating target protein half-lives in a predictable manner. Using the well-established tetracycline gene-regulation system as a model, we show that the dynamics of protein expression can be tuned by fusing appropriate degron tags to gene regulators. Next, we apply this degron library to tune a synthetic pulse-generating circuit in mammalian cells. With this toolbox we establish a set of pulse generators with tailored pulse lengths and magnitudes of protein expression. This methodology will prove useful in the functional roles of essential proteins, fine-tuning of gene-expression systems, and enabling a higher complexity in the design of synthetic biological systems in mammalian cells.","lang":"eng"}],"status":"public","author":[{"full_name":"Chassin, Hélène","last_name":"Chassin","first_name":"Hélène"},{"first_name":"Marius","last_name":"Müller","full_name":"Müller, Marius"},{"first_name":"Marcel","full_name":"Tigges, Marcel","last_name":"Tigges"},{"last_name":"Scheller","full_name":"Scheller, Leo","first_name":"Leo"},{"full_name":"Lang, Moritz","last_name":"Lang","id":"29E0800A-F248-11E8-B48F-1D18A9856A87","first_name":"Moritz"},{"first_name":"Martin","last_name":"Fussenegger","full_name":"Fussenegger, Martin"}],"publisher":"Springer Nature","external_id":{"isi":["000466338600006"]},"publication_status":"published","_id":"6465","issue":"1","ddc":["570"],"type":"journal_article","oa_version":"Published Version","file":[{"access_level":"open_access","content_type":"application/pdf","date_updated":"2020-07-14T12:47:31Z","file_size":1191827,"checksum":"e214d3e4f8c81e35981583c4569b51b8","date_created":"2019-05-20T07:33:54Z","file_name":"2019_NatureComm_Chassin.pdf","file_id":"6471","creator":"dernst","relation":"main_file"}],"month":"05","year":"2019","publication_identifier":{"eissn":["20411723"]},"isi":1,"department":[{"_id":"CaGu"}]},{"publisher":"Wiley","ddc":["580","576"],"file":[{"file_name":"2019_MolecularEcology_Field.pdf","relation":"main_file","creator":"dernst","file_id":"6472","date_updated":"2020-07-14T12:47:31Z","content_type":"application/pdf","access_level":"open_access","date_created":"2019-05-20T11:49:06Z","file_size":367711,"checksum":"521e3aff3e9263ddf2ffbfe0b6157715"}],"type":"journal_article","oa_version":"Published Version","issue":"7","_id":"6466","external_id":{"isi":["000474808300001"]},"publication_status":"published","isi":1,"publication_identifier":{"eissn":["1365294X"]},"year":"2019","month":"04","department":[{"_id":"NiBa"}],"date_updated":"2023-08-25T10:37:30Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"abstract":[{"text":"One of the most striking and consistent results in speciation genomics is the heterogeneous divergence observed across the genomes of closely related species. This pattern was initially attributed to different levels of gene exchange—with divergence preserved at loci generating a barrier to gene flow but homogenized at unlinked neutral loci. Although there is evidence to support this model, it is now recognized that interpreting patterns of divergence across genomes is not so straightforward. One \r\nproblem is that heterogenous divergence between populations can also be generated by other processes (e.g. recurrent selective sweeps or background selection) without any involvement of differential gene flow. Thus, integrated studies that identify which loci are likely subject to divergent selection are required to shed light on the interplay between selection and gene flow during the early phases of speciation. In this issue of Molecular Ecology, Rifkin et al. (2019) confront this challenge using a pair of sister morning glory species. They wisely design their sampling to take the geographic context of individuals into account, including geographically isolated (allopatric) and co‐occurring (sympatric) populations. This enabled them to show that individuals are phenotypically less differentiated in sympatry. They also found that the loci that resist introgression are enriched for those most differentiated in allopatry and loci that exhibit signals of divergent selection. One great strength of the \r\nstudy is the combination of methods from population genetics and molecular evolution, including the development of a model to simultaneously infer admixture proportions and selfing rates.","lang":"eng"}],"scopus_import":"1","author":[{"orcid":"0000-0002-4014-8478","full_name":"Field, David","last_name":"Field","first_name":"David","id":"419049E2-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Fraisse, Christelle","last_name":"Fraisse","orcid":"0000-0001-8441-5075","id":"32DF5794-F248-11E8-B48F-1D18A9856A87","first_name":"Christelle"}],"status":"public","oa":1,"date_created":"2019-05-19T21:59:15Z","citation":{"ama":"Field D, Fraisse C.

The amplitude of unitary [Ca2+] transients (evoked by a single action potential) negatively correlates with GCaMP6f expression, but displays large variability even among PCs with similarly low expression levels. The summation of fluorescence signals is frequency‐dependent, supralinear and also shows remarkable cell‐to‐cell variability. We performed experimental data‐based simulations and found that spike inference error rates using MLspike depend strongly on unitary peak amplitudes and GCaMP6f expression levels.

This communication between cells and their environment can be formalized in mathematical terms and be quantified as the information flow between them, as prescribed by information theory. \r\nThe recent availability of real–time dynamical patterns of signaling molecules in single cells has allowed us to identify encoding about the identity of the environment in the time–series. However, efficient estimation of the information transmitted by these signals has been a data–analysis challenge due to the high dimensionality of the trajectories and the limited number of samples. In the first part of this thesis, we develop and evaluate decoding–based estimation methods to lower bound the mutual information and derive model–based precise information estimates for biological reaction networks governed by the chemical master equation. This is followed by applying the decoding-based methods to study the intracellular representation of extracellular changes in budding yeast, by observing the transient dynamics of nuclear translocation of 10 transcription factors in response to 3 stress conditions. Additionally, we apply these estimators to previously published data on ERK and Ca2+ signaling and yeast stress response. We argue that this single cell decoding-based measure of information provides an unbiased, quantitative and interpretable measure for the fidelity of biological signaling processes. \r\nFinally, in the last section, we deal with gene regulation which is primarily controlled by transcription factors (TFs) that bind to the DNA to activate gene expression. The possibility that non-cognate TFs activate transcription diminishes the accuracy of regulation with potentially disastrous effects for the cell. This ’crosstalk’ acts as a previously unexplored source of noise in biochemical networks and puts a strong constraint on their performance. To mitigate erroneous initiation we propose an out of equilibrium scheme that implements kinetic proofreading. We show that such architectures are favored over their equilibrium counterparts for complex organisms despite introducing noise in gene expression.

However, not all systems fall into this category, with many-body localization providinga generic mechanism for thermalization to fail in strongly disordered systems. Many-bodylocalized (MBL) systems remain perfect insulators at nonzero temperature, which do notthermalize and therefore cannot be describedusing statistical mechanics. This Colloquiumreviews recent theoretical and experimental advances in studies of MBL systems, focusing onthe new perspective provided by entanglement and nonequilibrium experimental probes suchas quantum quenches. Theoretically, MBL systems exhibit a new kind of robust integrability: anextensive set of quasilocal integrals of motion emerges, which provides an intuitive explanationof the breakdown of thermalization. A description based on quasilocal integrals of motion isused to predict dynamical properties of MBL systems, such as the spreading of quantumentanglement, the behavior of local observables, and the response to external dissipativeprocesses. Furthermore, MBL systems can exhibit eigenstate transitions and quantum ordersforbidden in thermodynamic equilibrium. An outline isgiven of the current theoretical under-standing of the quantum-to-classical transitionbetween many-body localized and ergodic phasesand anomalous transport in the vicinity of that transition. Experimentally, synthetic quantumsystems, which are well isolated from an external thermal reservoir, provide natural platforms forrealizing the MBL phase. Recent experiments with ultracold atoms, trapped ions, superconductingqubits, and quantum materials, in which different signatures of many-body localization have beenobserved, are reviewed.

A major open problem in this context, however, is quality control. Good classification performance can only be expected if systems run under the specific conditions, in particular data distributions, that they were trained for. Surprisingly, none of the currently used deep network architectures have a built-in functionality that could detect if a network operates on data from a distribution it was not trained for, such that potentially a warning to the human users could be triggered. In this work, we describe KS(conf), a procedure for detecting such outside of specifications (out-of-specs) operation, based on statistical testing of the network outputs. We show by extensive experiments using the ImageNet, AwA2 and DAVIS datasets on a variety of ConvNets architectures that KS(conf) reliably detects out-of-specs situations. It furthermore has a number of properties that make it a promising candidate for practical deployment: it is easy to implement, adds almost no overhead to the system, works with all networks, including pretrained ones, and requires no a priori knowledge of how the data distribution could change.

The custom-shaped honeycombs are used as stationary flow management devices which generate specific modifications of the streamwise velocity profile. Stereoscopic particle image velocimetry and pressure drop measurements are used to investigate and capture the development of the relaminarizing flow downstream these devices. We compare the performance of straight (constant length across the radius of the pipe) honeycombs with custom-shaped ones (variable length across the radius) and try to determine the optimal shape for maximal relaminarization at minimal pressure loss. The optimally modified streamwise velocity profile is found to be M-shaped, and the maximum attainable Reynolds number for total relaminarization is found to be of the order of 10,000. Consequently, the respective reduction in skin friction downstream of the device is almost by a factor of 5. The break-even point, where the additional pressure drop caused by the device is balanced by the savings due to relaminarization and a net gain is obtained, corresponds to a downstream stretch of distances as low as approximately 100 pipe diameters of laminar flow."}],"scopus_import":"1","date_updated":"2024-03-25T23:30:20Z","language":[{"iso":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","title":"Relaminarization of pipe flow by means of 3D-printed shaped honeycombs","date_created":"2019-05-26T21:59:13Z","acknowledged_ssus":[{"_id":"M-Shop"}],"citation":{"mla":"Kühnen, Jakob, et al. “Relaminarization of Pipe Flow by Means of 3D-Printed Shaped Honeycombs.” Journal of Fluids Engineering, vol. 141, no. 11, 111105, ASME, 2019, doi:10.1115/1.4043494.","chicago":"Kühnen, Jakob, Davide Scarselli, and Björn Hof. “Relaminarization of Pipe Flow by Means of 3D-Printed Shaped Honeycombs.” Journal of Fluids Engineering.

Two important problems regarding smart contracts are formal analysis and compiler optimization. Formal analysis is extremely important, because smart contracts hold funds worth billions of dollars and their code is immutable after deployment. Hence, an undetected bug can cause significant financial losses. Compiler optimization is also crucial, because every action of a smart contract has to be executed by every node in the Blockchain network. Therefore, optimizations in compiling smart contracts can lead to significant savings in computation, time and energy.\r\n\r\nTwo classical approaches in program analysis and compiler optimization are intraprocedural and interprocedural analysis. In intraprocedural analysis, each function is analyzed separately, while interprocedural analysis considers the entire program. In both cases, the analyses are usually reduced to graph problems over the control flow graph (CFG) of the program. These graph problems are often computationally expensive. Hence, there has been ample research on exploiting structural properties of CFGs for efficient algorithms. One such well-studied property is the treewidth, which is a measure of tree-likeness of graphs. It is known that intraprocedural CFGs of structured programs have treewidth at most 6, whereas the interprocedural treewidth cannot be bounded. This result has been used as a basis for many efficient intraprocedural analyses.\r\n\r\nIn this paper, we explore the idea of exploiting the treewidth of smart contracts for formal analysis and compiler optimization. First, similar to classical programs, we show that the intraprocedural treewidth of structured Solidity and Vyper smart contracts is at most 9. Second, for global analysis, we prove that the interprocedural treewidth of structured smart contracts is bounded by 10 and, in sharp contrast with classical programs, treewidth-based algorithms can be easily applied for interprocedural analysis. Finally, we supplement our theoretical results with experiments using a tool we implemented for computing treewidth of smart contracts and show that the treewidth is much lower in practice. We use 36,764 real-world Ethereum smart contracts as benchmarks and find that they have an average treewidth of at most 3.35 for the intraprocedural case and 3.65 for the interprocedural case.\r\n"}],"scopus_import":"1","date_updated":"2024-03-25T23:30:18Z","language":[{"iso":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","status":"public","author":[{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu"},{"first_name":"Amir Kafshdar","id":"391365CE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-1702-6584","last_name":"Goharshady","full_name":"Goharshady, Amir Kafshdar"},{"full_name":"Goharshady, Ehsan Kafshdar","last_name":"Goharshady","first_name":"Ehsan Kafshdar"}],"citation":{"mla":"Chatterjee, Krishnendu, et al. “The Treewidth of Smart Contracts.” Proceedings of the 34th ACM Symposium on Applied Computing, vol.

Unlike previous approaches, our algorithms work without a template and generate an automaton with nondeterministic guards and invariants, and with an arbitrary number and topology of modes. They thus construct a succinct model from the data and provide formal guarantees. In particular, (1) the generated automaton can reproduce the data up to a specified tolerance and (2) the automaton is tight, given the first guarantee. Our first approach encodes the synthesis problem as a logical formula in the theory of linear arithmetic, which can then be solved by an SMT solver. This approach minimizes the number of modes in the resulting model but is only feasible for limited data sets. To address scalability, we propose a second approach that does not enforce to find a minimal model. The algorithm constructs an initial automaton and then iteratively extends the automaton based on processing new data. Therefore the algorithm is well-suited for online and synthesis-in-the-loop applications. The core of the algorithm is a membership query that checks whether, within the specified tolerance, a given data set can result from the execution of a given automaton. We solve this membership problem for linear hybrid automata by repeated reachability computations. We demonstrate the effectiveness of the algorithm on synthetic data sets and on cardiac-cell measurements.","lang":"eng"}],"keyword":["Synthesis","Linear hybrid automaton","Membership"],"scopus_import":"1","date_updated":"2023-08-25T10:40:41Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"author":[{"full_name":"Garcia Soto, Miriam","last_name":"Garcia Soto","orcid":"0000−0003−2936−5719","id":"4B3207F6-F248-11E8-B48F-1D18A9856A87","first_name":"Miriam"},{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A","full_name":"Henzinger, Thomas A","last_name":"Henzinger","orcid":"0000−0002−2985−7724"},{"first_name":"Christian","id":"3A2F4DCE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3658-1065","full_name":"Schilling, Christian","last_name":"Schilling"},{"last_name":"Zeleznik","full_name":"Zeleznik, Luka","id":"3ADCA2E4-F248-11E8-B48F-1D18A9856A87","first_name":"Luka"}],"status":"public","oa_version":"Published Version","ddc":["000"],"file":[{"date_updated":"2020-07-14T12:47:32Z","content_type":"application/pdf","access_level":"open_access","date_created":"2019-08-14T11:05:30Z","file_size":674795,"checksum":"1f1d61b83a151031745ef70a501da3d6","file_name":"2019_CAV_GarciaSoto.pdf","relation":"main_file","creator":"dernst","file_id":"6817"}],"type":"conference","_id":"6493","publication_status":"published","alternative_title":["LNCS"],"external_id":{"isi":["000491468000016"]},"publisher":"Springer","department":[{"_id":"ToHe"}],"isi":1,"publication_identifier":{"issn":["0302-9743"],"isbn":["9783030255398"]},"year":"2019","month":"07","project":[{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"},{"grant_number":"S 11407_N23","call_identifier":"FWF","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425"},{"grant_number":"Z211","_id":"25F42A32-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"The Wittgenstein Prize"}]},{"doi":"10.1016/j.jde.2018.09.012","article_processing_charge":"No","day":"5","publication":"Journal of Differential Equations","volume":266,"intvolume":" 266","date_published":"2019-03-05T00:00:00Z","publist_id":"7989","page":"3732-3763","title":"Entropy solutions for stochastic porous media equations","oa":1,"citation":{"mla":"Dareiotis, Konstantinos, et al. “Entropy Solutions for Stochastic Porous Media Equations.” Journal of Differential Equations, vol. 266, no. 6, Elsevier, 2019, pp. 3732–63, doi:10.1016/j.jde.2018.09.012.","chicago":"Dareiotis, Konstantinos, Mate Gerencser, and Benjamin Gess. “Entropy Solutions for Stochastic Porous Media Equations.” Journal of Differential Equations.

Here, we measured the effects of a set of Bacillus subtilis glutamate dehydrogenase mutants across 19 different environments—from phenotypically homogeneous single-cell populations in liquid media to heterogeneous biofilms, plant roots and soil populations. The effects of individual gene mutations on organismal fitness were highly reproducible in liquid cultures. However, 84% of the tested alleles showed opposing fitness effects under different growth conditions (sign environmental pleiotropy). In colony biofilms and soil samples, different alleles dominated in parallel replica experiments. Accordingly, we found that in these heterogeneous cell populations the fate of mutations was dictated by a combination of selection and drift. The latter relates to programmed prophage excisions that occurred during biofilm development. Overall, for each condition, a wide range of glutamate dehydrogenase mutations persisted and sometimes fixated as a result of the combined action of selection, pleiotropy and chance. However, over longer periods and in multiple environments, nearly all of this diversity would be lost—across all the environments and conditions that we tested, the wild type was the fittest allele."}],"scopus_import":"1","date_updated":"2023-08-28T08:39:47Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"status":"public","author":[{"last_name":"Noda-García","full_name":"Noda-García, Lianet","first_name":"Lianet"},{"first_name":"Dan","full_name":"Davidi, Dan","last_name":"Davidi"},{"first_name":"Elisa","last_name":"Korenblum","full_name":"Korenblum, Elisa"},{"first_name":"Assaf","last_name":"Elazar","full_name":"Elazar, Assaf"},{"first_name":"Ekaterina","id":"2EF67C84-F248-11E8-B48F-1D18A9856A87","full_name":"Putintseva, Ekaterina","last_name":"Putintseva"},{"first_name":"Asaph","full_name":"Aharoni, Asaph","last_name":"Aharoni"},{"last_name":"Tawfik","full_name":"Tawfik, Dan S.","first_name":"Dan S."}],"oa_version":"Preprint","type":"journal_article","publication_status":"published","external_id":{"isi":["000480348200017"]},"issue":"7","_id":"6506","publisher":"Springer Nature","department":[{"_id":"FyKo"}],"article_type":"original","publication_identifier":{"issn":["2058-5276"]},"isi":1,"year":"2019","month":"07"},{"quality_controlled":"1","acknowledged_ssus":[{"_id":"Bio"},{"_id":"PreCl"}],"citation":{"chicago":"Shamipour, Shayan, Roland Kardos, Shi-lei Xue, Björn Hof, Edouard B Hannezo, and Carl-Philipp J Heisenberg. “Bulk Actin Dynamics Drive Phase Segregation in Zebrafish Oocytes.” Cell.

In zebrafish oocytes, extensive ooplasmic streaming leads to the segregation of ooplasm from yolk granules along the animal-vegetal axis of the oocyte. Here, we show that this process does not rely on cortical actin reorganization, as previously thought, but instead on a cell-cycle-dependent bulk actin polymerization wave traveling from the animal to the vegetal pole of the oocyte. This wave functions in segregation by both pulling ooplasm animally and pushing yolk granules vegetally. Using biophysical experimentation and theory, we show that ooplasm pulling is mediated by bulk actin network flows exerting friction forces on the ooplasm, while yolk granule pushing is achieved by a mechanism closely resembling actin comet formation on yolk granules. Our study defines a novel role of cell-cycle-controlled bulk actin polymerization waves in oocyte polarization via ooplasmic segregation.","lang":"eng"}],"language":[{"iso":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2024-03-25T23:30:21Z","status":"public","author":[{"full_name":"Shamipour, Shayan","last_name":"Shamipour","id":"40B34FE2-F248-11E8-B48F-1D18A9856A87","first_name":"Shayan"},{"last_name":"Kardos","full_name":"Kardos, Roland","id":"4039350E-F248-11E8-B48F-1D18A9856A87","first_name":"Roland"},{"last_name":"Xue","full_name":"Xue, Shi-lei","id":"31D2C804-F248-11E8-B48F-1D18A9856A87","first_name":"Shi-lei"},{"id":"3A374330-F248-11E8-B48F-1D18A9856A87","first_name":"Björn","orcid":"0000-0003-2057-2754","full_name":"Hof, Björn","last_name":"Hof"},{"first_name":"Edouard B","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","last_name":"Hannezo","full_name":"Hannezo, Edouard B","orcid":"0000-0001-6005-1561"},{"id":"39427864-F248-11E8-B48F-1D18A9856A87","first_name":"Carl-Philipp J","orcid":"0000-0002-0912-4566","full_name":"Heisenberg, Carl-Philipp J","last_name":"Heisenberg"}]},{"author":[{"first_name":"Zhigang","id":"442E6A6C-F248-11E8-B48F-1D18A9856A87","last_name":"Bao","full_name":"Bao, Zhigang","orcid":"0000-0003-3036-1475"},{"first_name":"László","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5366-9603","last_name":"Erdös","full_name":"Erdös, László"},{"id":"434AD0AE-F248-11E8-B48F-1D18A9856A87","first_name":"Kevin","orcid":"0000-0003-0954-3231","full_name":"Schnelli, Kevin","last_name":"Schnelli"}],"status":"public","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"date_updated":"2023-08-28T09:32:29Z","scopus_import":"1","abstract":[{"text":"Let U and V be two independent N by N random matrices that are distributed according to Haar measure on U(N).

The same results hold true when U and V are Haar distributed on O(N).","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1612.05920","open_access":"1"}],"year":"2019","month":"05","project":[{"grant_number":"338804","name":"Random matrices, universality and disordered quantum systems","call_identifier":"FP7","_id":"258DCDE6-B435-11E9-9278-68D0E5697425"}],"isi":1,"publication_identifier":{"issn":["00911798"]},"department":[{"_id":"LaEr"}],"publisher":"Institute of Mathematical Statistics","issue":"3","_id":"6511","external_id":{"isi":["000466616100003"],"arxiv":["1612.05920"]},"publication_status":"published","oa_version":"Preprint","type":"journal_article","doi":"10.1214/18-AOP1284","ec_funded":1,"article_processing_charge":"No","volume":47,"publication":"Annals of Probability","day":"01","date_published":"2019-05-01T00:00:00Z","intvolume":" 47","page":"1270-1334","title":"Local single ring theorem on optimal scale","oa":1,"quality_controlled":"1","arxiv":1,"date_created":"2019-06-02T21:59:13Z","citation":{"mla":"Bao, Zhigang, et al. “Local Single Ring Theorem on Optimal Scale.” Annals of Probability, vol. 47, no. 3, Institute of Mathematical Statistics, 2019, pp. 1270–334, doi:10.1214/18-AOP1284.","chicago":"Bao, Zhigang, László Erdös, and Kevin Schnelli. “Local Single Ring Theorem on Optimal Scale.” Annals of Probability.

Although fetal LGR5-expressing cells can give rise to adult intestinal stem cells3,4, it remains unclear whether this population in the patterned epithelium represents unique intestinal stem-cell precursors. Here we show, using unbiased quantitative lineage-tracing approaches, biophysical modelling and intestinal transplantation, that all cells of the mouse intestinal epithelium—irrespective of their location and pattern of LGR5 expression in the fetal gut tube—contribute actively to the adult intestinal stem cell pool. Using 3D imaging, we find that during fetal development the villus undergoes gross remodelling and fission. This brings epithelial cells from the non-proliferative villus into the proliferative intervillus region, which enables them to contribute to the adult stem-cell niche. Our results demonstrate that large-scale remodelling of the intestinal wall and cell-fate specification are closely linked. Moreover, these findings provide a direct link between the observed plasticity and cellular reprogramming of differentiating cells in adult tissues following damage5,6,7,8,9, revealing that stem-cell identity is an induced rather than a hardwired property.","lang":"eng"}],"status":"public","author":[{"first_name":"Jordi","last_name":"Guiu","full_name":"Guiu, Jordi"},{"last_name":"Hannezo","full_name":"Hannezo, Edouard B","orcid":"0000-0001-6005-1561","first_name":"Edouard B","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Shiro","last_name":"Yui","full_name":"Yui, Shiro"},{"last_name":"Demharter","full_name":"Demharter, Samuel","first_name":"Samuel"},{"first_name":"Svetlana","full_name":"Ulyanchenko, Svetlana","last_name":"Ulyanchenko"},{"first_name":"Martti","last_name":"Maimets","full_name":"Maimets, Martti"},{"first_name":"Anne","full_name":"Jørgensen, Anne","last_name":"Jørgensen"},{"first_name":"Signe","full_name":"Perlman, Signe","last_name":"Perlman"},{"full_name":"Lundvall, Lene","last_name":"Lundvall","first_name":"Lene"},{"first_name":"Linn Salto","last_name":"Mamsen","full_name":"Mamsen, Linn Salto"},{"first_name":"Agnete","full_name":"Larsen, Agnete","last_name":"Larsen"},{"full_name":"Olesen, Rasmus H.","last_name":"Olesen","first_name":"Rasmus H."},{"first_name":"Claus Yding","last_name":"Andersen","full_name":"Andersen, Claus Yding"},{"last_name":"Thuesen","full_name":"Thuesen, Lea Langhoff","first_name":"Lea Langhoff"},{"last_name":"Hare","full_name":"Hare, Kristine Juul","first_name":"Kristine Juul"},{"last_name":"Pers","full_name":"Pers, Tune H.","first_name":"Tune H."},{"last_name":"Khodosevich","full_name":"Khodosevich, Konstantin","first_name":"Konstantin"},{"last_name":"Simons","full_name":"Simons, Benjamin D.","first_name":"Benjamin D."},{"full_name":"Jensen, Kim B.","last_name":"Jensen","first_name":"Kim B."}],"publisher":"Springer Nature","external_id":{"isi":["000470149000048"],"pmid":["31092921"]},"publication_status":"published","_id":"6513","type":"journal_article","oa_version":"Submitted Version","year":"2019","month":"06","publication_identifier":{"eissn":["14764687"],"issn":["00280836"]},"isi":1,"article_type":"original","department":[{"_id":"EdHa"}]}]
