We describe a comprehensive de novo assembled transcriptome in the common frog Rana temporaria based on five developmental stages and three adult tissues from both sexes, obtained from a population with karyotypically homomorphic but genetically differentiated sex chromosomes. This allows the study of sex-biased gene expression throughout development, and its effect on the rate of gene evolution while accounting for pleiotropic expression, which is known to negatively correlate with the evolutionary rate. Overall, sex-biased genes had little overlap among developmental stages and adult tissues. Late developmental stages and gonad tissues had the highest numbers of stage-or tissue-specific genes. We find that pleiotropic gene expression is a better predictor than sex bias for the evolutionary rate of genes, though it often interacts with sex bias. Although genetically differentiated, the sex chromosomes were not enriched in sex-biased genes, possibly due to a very recent arrest of XY recombination. These results extend our understanding of the developmental dynamics, tissue specificity, and genomic localization of sex-biased genes."}],"date_published":"2018-06-12T00:00:00Z","status":"public","publication":"Genes","publist_id":"7714","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","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"},"intvolume":" 9","title":"Tissue specificity and dynamics of sex biased gene expression in a common frog population with differentiated, yet homomorphic, sex chromosomes","doi":"10.3390/genes9060294","isi":1,"external_id":{"isi":["000436494200026"]},"day":"12","date_updated":"2023-09-19T10:15:31Z","has_accepted_license":"1","year":"2018","article_processing_charge":"No","oa":1,"file_date_updated":"2020-07-14T12:45:22Z","article_number":"294","month":"06","file":[{"access_level":"open_access","date_created":"2019-02-01T07:52:28Z","date_updated":"2020-07-14T12:45:22Z","file_size":3985796,"file_id":"5905","relation":"main_file","file_name":"2018_Genes_Ma.pdf","creator":"dernst","checksum":"423069beb1cd3cdd25bf3f464b38f1d7","content_type":"application/pdf"}],"author":[{"full_name":"Ma, Wen","first_name":"Wen","last_name":"Ma"},{"last_name":"Veltsos","first_name":"Paris","full_name":"Veltsos, Paris"},{"id":"4E099E4E-F248-11E8-B48F-1D18A9856A87","first_name":"Melissa A","last_name":"Toups","full_name":"Toups, Melissa A","orcid":"0000-0002-9752-7380"},{"first_name":"Nicolas","last_name":"Rodrigues","full_name":"Rodrigues, Nicolas"},{"last_name":"Sermier","first_name":"Roberto","full_name":"Sermier, Roberto"},{"last_name":"Jeffries","first_name":"Daniel","full_name":"Jeffries, Daniel"},{"full_name":"Perrin, Nicolas","first_name":"Nicolas","last_name":"Perrin"}],"citation":{"ama":"Ma W, Veltsos P, Toups MA, et al.

A crucial question in indirect reciprocity is which social norms can maintain stable cooperation in a society. Past research has highlighted eight such norms, called “leading-eight” strategies. This past research, however, is based on the assumption that all relevant information about other population members is publicly available and that everyone agrees on who is good or bad. Instead, here we explore the reputation dynamics when information is private and noisy. We show that under these conditions, most leading-eight strategies fail to evolve. Those leading-eight strategies that do evolve are unable to sustain full cooperation.Indirect reciprocity is a mechanism for cooperation based on shared moral systems and individual reputations. It assumes that members of a community routinely observe and assess each other and that they use this information to decide who is good or bad, and who deserves cooperation. When information is transmitted publicly, such that all community members agree on each other’s reputation, previous research has highlighted eight crucial moral systems. These “leading-eight” strategies can maintain cooperation and resist invasion by defectors. However, in real populations individuals often hold their own private views of others. Once two individuals disagree about their opinion of some third party, they may also see its subsequent actions in a different light. Their opinions may further diverge over time. Herein, we explore indirect reciprocity when information transmission is private and noisy. We find that in the presence of perception errors, most leading-eight strategies cease to be stable. Even if a leading-eight strategy evolves, cooperation rates may drop considerably when errors are common. Our research highlights the role of reliable information and synchronized reputations to maintain stable moral systems.","lang":"eng"}],"intvolume":" 115","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa_version":"Submitted Version","date_created":"2018-12-11T11:44:05Z","scopus_import":"1","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pubmed/30429320","open_access":"1"}],"volume":115,"type":"journal_article","pmid":1,"project":[{"name":"Quantitative Graph Games: Theory and Applications","_id":"2581B60A-B435-11E9-9278-68D0E5697425","grant_number":"279307","call_identifier":"FP7"},{"grant_number":"P 23499-N23","_id":"2584A770-B435-11E9-9278-68D0E5697425","name":"Modern Graph Algorithmic Techniques in Formal Verification","call_identifier":"FWF"},{"call_identifier":"FWF","grant_number":"S 11407_N23","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FP7","_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme","grant_number":"291734"}],"quality_controlled":"1","department":[{"_id":"KrCh"}],"publisher":"National Academy of Sciences","publication_status":"published","issue":"48","page":"12241-12246","_id":"2","language":[{"iso":"eng"}],"month":"11","author":[{"first_name":"Christian","last_name":"Hilbe","id":"2FDF8F3C-F248-11E8-B48F-1D18A9856A87","full_name":"Hilbe, Christian","orcid":"0000-0001-5116-955X"},{"id":"38B437DE-F248-11E8-B48F-1D18A9856A87","first_name":"Laura","last_name":"Schmid","orcid":"0000-0002-6978-7329","full_name":"Schmid, Laura"},{"orcid":"0000-0002-1097-9684","full_name":"Tkadlec, Josef","first_name":"Josef","last_name":"Tkadlec","id":"3F24CCC8-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Chatterjee","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X"},{"last_name":"Nowak","first_name":"Martin","full_name":"Nowak, Martin"}],"citation":{"ama":"Hilbe C, Schmid L, Tkadlec J, Chatterjee K, Nowak M.

However, acute effects of NE stimulation have not been described at the transcriptional network level. Results: We used RNA-seq to uncover a broad transcriptional response. The inference of protein-protein and protein-DNA interaction networks allowed us to identify a set of immediate-early genes (IEGs) with high betweenness, validating our approach and suggesting a hierarchical control of transcriptional regulation. In addition, we identified a transcriptional regulatory network with IEGs as master regulators, including HSF1 and NFIL3 as novel NE-induced IEG candidates. Moreover, a functional enrichment analysis and gene clustering into functional modules suggest a crosstalk between metabolic, signaling, and immune responses. Conclusions: Altogether, our network biology approach explores for the first time the immediate-early systems level response of human adipocytes to acute sympathetic activation, thereby providing a first network basis of early cell fate programs and crosstalks between metabolic and transcriptional networks required for proper WAT function."}],"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"},"intvolume":" 19","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","quality_controlled":"1","department":[{"_id":"SiHi"}],"publisher":"BioMed Central","publication_status":"published","type":"journal_article","volume":19,"file":[{"content_type":"application/pdf","file_name":"2018_BMCGenomics_Higareda.pdf","relation":"main_file","checksum":"a56516e734dab589dc7f3e1915973b4d","creator":"dernst","file_size":4629784,"file_id":"5712","access_level":"open_access","date_created":"2018-12-17T14:52:57Z","date_updated":"2020-07-14T12:45:23Z"}],"author":[{"first_name":"Juan","last_name":"Higareda Almaraz","full_name":"Higareda Almaraz, Juan"},{"full_name":"Karbiener, Michael","first_name":"Michael","last_name":"Karbiener"},{"last_name":"Giroud","first_name":"Maude","full_name":"Giroud, Maude"},{"orcid":"0000-0002-7462-0048","full_name":"Pauler, Florian","first_name":"Florian","last_name":"Pauler","id":"48EA0138-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Gerhalter","first_name":"Teresa","full_name":"Gerhalter, Teresa"},{"last_name":"Herzig","first_name":"Stephan","full_name":"Herzig, Stephan"},{"last_name":"Scheideler","first_name":"Marcel","full_name":"Scheideler, Marcel"}],"file_date_updated":"2020-07-14T12:45:23Z","month":"11","ddc":["570"],"citation":{"ieee":"J.

The underlying idea is that population structure affects its spatial genetic structure. Therefore, genotype information can be utilized to estimate important demographic parameters such as migration rates. These indirect estimates of population structure have become very attractive, as genotype data is now widely available. However, there also has been much concern about these approaches. Importantly, genetic structure can be influenced by many complex patterns, which often cannot be disentangled. Moreover, many methods merely fit heuristic patterns of genetic structure, and do not build upon population genetics theory. Here, I describe two novel inference methods that address these shortcomings. In Chapter 2, I introduce an inference scheme based on a new type of signal, identity by descent (IBD) blocks. Recently, it has become feasible to detect such long blocks of genome shared between pairs of samples. These blocks are direct traces of recent coalescence events. As such, they contain ample signal for inferring recent demography. I examine sharing of IBD blocks in two-dimensional populations with local migration. Using a diffusion approximation, I derive formulas for an isolation by distance pattern of long IBD blocks and show that sharing of long IBD blocks approaches rapid exponential decay for growing sample distance. I describe an inference scheme based on these results. It can robustly estimate the dispersal rate and population density, which is demonstrated on simulated data. I also show an application to estimate mean migration and the rate of recent population growth within Eastern Europe. Chapter 3 is about a novel method to estimate barriers to gene flow in a two dimensional population. This inference scheme utilizes geographically localized allele frequency fluctuations - a classical isolation by distance signal. The strength of these local fluctuations increases on average next to a barrier, and there is less correlation across it. I again use a framework of diffusion of ancestral lineages to model this effect, and provide an efficient numerical implementation to fit the results to geo-referenced biallelic SNP data. This inference scheme is able to robustly estimate strong barriers to gene flow, as tests on simulated data confirm.","lang":"eng"}],"status":"public","date_published":"2018-02-21T00:00:00Z","publist_id":"7713","publication_status":"published","publisher":"Institute of Science and Technology Austria","department":[{"_id":"NiBa"}],"supervisor":[{"orcid":"0000-0002-8548-5240","full_name":"Barton, Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","first_name":"Nicholas H","last_name":"Barton"}],"type":"dissertation"},{"type":"dissertation","supervisor":[{"orcid":"0000-0002-9823-6833","full_name":"Edelsbrunner, Herbert","last_name":"Edelsbrunner","first_name":"Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87"}],"department":[{"_id":"HeEd"}],"publisher":"Institute of Science and Technology Austria","publication_status":"published","publist_id":"7712","date_published":"2018-06-11T00:00:00Z","status":"public","abstract":[{"text":"We describe arrangements of three-dimensional spheres from a geometrical and topological point of view. Real data (fitting this setup) often consist of soft spheres which show certain degree of deformation while strongly packing against each other. In this context, we answer the following questions: If we model a soft packing of spheres by hard spheres that are allowed to overlap, can we measure the volume in the overlapped areas? Can we be more specific about the overlap volume, i.e. quantify how much volume is there covered exactly twice, three times, or k times? What would be a good optimization criteria that rule the arrangement of soft spheres while making a good use of the available space? Fixing a particular criterion, what would be the optimal sphere configuration? The first result of this thesis are short formulas for the computation of volumes covered by at least k of the balls. The formulas exploit information contained in the order-k Voronoi diagrams and its closely related Level-k complex. The used complexes lead to a natural generalization into poset diagrams, a theoretical formalism that contains the order-k and degree-k diagrams as special cases. In parallel, we define different criteria to determine what could be considered an optimal arrangement from a geometrical point of view. Fixing a criterion, we find optimal soft packing configurations in 2D and 3D where the ball centers lie on a lattice. As a last step, we use tools from computational topology on real physical data, to show the potentials of higher-order diagrams in the description of melting crystals. The results of the experiments leaves us with an open window to apply the theories developed in this thesis in real applications.","lang":"eng"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa_version":"Published Version","date_created":"2018-12-11T11:45:10Z","alternative_title":["ISTA Thesis"],"year":"2018","has_accepted_license":"1","article_processing_charge":"No","oa":1,"doi":"10.15479/AT:ISTA:th_1026","title":"Multiple covers with balls","date_updated":"2023-09-07T12:25:32Z","day":"11","publication_identifier":{"issn":["2663-337X"]},"page":"171","_id":"201","pubrep_id":"1026","language":[{"iso":"eng"}],"degree_awarded":"PhD","file":[{"access_level":"closed","date_updated":"2020-07-14T12:45:24Z","date_created":"2019-02-05T07:43:31Z","file_size":11827713,"file_id":"5918","relation":"source_file","file_name":"IST-2018-1025-v2+5_ist-thesis-iglesias-11June2018(1).zip","creator":"kschuh","checksum":"dd699303623e96d1478a6ae07210dd05","content_type":"application/zip"},{"file_size":4783846,"file_id":"5919","access_level":"open_access","date_created":"2019-02-05T07:43:45Z","date_updated":"2020-07-14T12:45:24Z","content_type":"application/pdf","relation":"main_file","file_name":"IST-2018-1025-v2+4_ThesisIglesiasFinal11June2018.pdf","creator":"kschuh","checksum":"ba163849a190d2b41d66fef0e4983294"}],"author":[{"last_name":"Iglesias Ham","first_name":"Mabel","id":"41B58C0C-F248-11E8-B48F-1D18A9856A87","full_name":"Iglesias Ham, Mabel"}],"file_date_updated":"2020-07-14T12:45:24Z","month":"06","ddc":["514","516"],"citation":{"apa":"Iglesias Ham, M.

Local differences in auxin concentrations are achieved mainly by polarized cellular distribution of PIN auxin transporters, but whether other mechanisms involving auxin homeostasis are also relevant for the formation of auxin gradients is not clear. Here we show that auxin methylation is required for asymmetric auxin distribution across the hypocotyl, particularly during its response to gravity. We found that loss-of-function mutants in Arabidopsis IAA CARBOXYL METHYLTRANSFERASE1 (IAMT1) prematurely unfold the apical hook, and that their hypocotyls are impaired in gravitropic reorientation. This defect is linked to an auxin-dependent increase in PIN gene expression, leading to an increased polar auxin transport and lack of asymmetric distribution of PIN3 in the iamt1 mutant. Gravitropic reorientation in the iamt1 mutant could be restored with either endodermis-specific expression of IAMT1 or partial inhibition of polar auxin transport, which also results in normal PIN gene expression levels. We propose that IAA methylation is necessary in gravity-sensing cells to restrict polar auxin transport within the range of auxin levels that allow for differential responses."}],"publist_id":"7710","publication":"PNAS","status":"public","date_published":"2018-06-26T00:00:00Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","intvolume":" 115","oa_version":"None","scopus_import":"1","date_created":"2018-12-11T11:45:11Z","main_file_link":[{"url":"http://eprints.nottingham.ac.uk/52388/","open_access":"1"}],"type":"journal_article","volume":115,"department":[{"_id":"JiFr"}],"quality_controlled":"1","project":[{"call_identifier":"FP7","_id":"25716A02-B435-11E9-9278-68D0E5697425","name":"Polarity and subcellular dynamics in plants","grant_number":"282300"}],"publication_status":"published","publisher":"National Academy of Sciences"},{"month":"07","article_number":"94","file_date_updated":"2020-07-14T12:44:45Z","file":[{"relation":"main_file","file_name":"2018_ACM_Jeschke.pdf","creator":"dernst","checksum":"db75ebabe2ec432bf41389e614d6ef62","content_type":"application/pdf","access_level":"open_access","date_created":"2018-12-18T09:59:23Z","date_updated":"2020-07-14T12:44:45Z","file_size":22185016,"file_id":"5744"}],"author":[{"full_name":"Jeschke, Stefan","last_name":"Jeschke","first_name":"Stefan","id":"44D6411A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Skrivan, Tomas","last_name":"Skrivan","first_name":"Tomas","id":"486A5A46-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Mueller Fischer","first_name":"Matthias","full_name":"Mueller Fischer, Matthias"},{"last_name":"Chentanez","first_name":"Nuttapong","full_name":"Chentanez, Nuttapong"},{"full_name":"Macklin, Miles","last_name":"Macklin","first_name":"Miles"},{"orcid":"0000-0001-6646-5546","full_name":"Wojtan, Christopher J","id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87","last_name":"Wojtan","first_name":"Christopher J"}],"citation":{"ieee":"S.

This paper attempts to bridge this long-standing gap between complexity and performance, by proposing a new wave simulation method that can faithfully simulate wave interactions with moving obstacles in real time while simultaneously preserving minute details and accommodating very large simulation domains.\r\n\r\nPrevious methods for simulating 2D water waves directly compute the change in height of the water surface, a strategy which imposes limitations based on the CFL condition (fast moving waves require small time steps) and Nyquist's limit (small wave details require closely-spaced simulation variables). This paper proposes a novel wavelet transformation that discretizes the liquid motion in terms of amplitude-like functions that vary over space, frequency, and direction, effectively generalizing Fourier-based methods to handle local interactions. Because these new variables change much more slowly over space than the original water height function, our change of variables drastically reduces the limitations of the CFL condition and Nyquist limit, allowing us to simulate highly detailed water waves at very large visual resolutions. Our discretization is amenable to fast summation and easy to parallelize. We also present basic extensions like pre-computed wave paths and two-way solid fluid coupling. Finally, we argue that our discretization provides a convenient set of variables for artistic manipulation, which we illustrate with a novel wave-painting interface."}],"tmp":{"image":"/images/cc_by_nc_sa.png","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","short":"CC BY-NC-SA (4.0)"},"intvolume":" 37","user_id":"2EBD1598-F248-11E8-B48F-1D18A9856A87","project":[{"name":"Efficient Simulation of Natural Phenomena at Extremely Large Scales","_id":"2533E772-B435-11E9-9278-68D0E5697425","grant_number":"638176","call_identifier":"H2020"},{"grant_number":"665385","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"quality_controlled":"1","department":[{"_id":"ChWo"}],"acknowledged_ssus":[{"_id":"ScienComp"}],"publisher":"ACM","publication_status":"published","volume":37,"type":"journal_article"},{"date_updated":"2023-09-11T14:00:26Z","day":"22","publication_identifier":{"issn":["0167-7055"]},"external_id":{"isi":["000434085600016"]},"isi":1,"doi":"10.1111/cgf.13351","title":"Extended narrow band FLIP for liquid simulations","article_processing_charge":"No","oa":1,"year":"2018","ec_funded":1,"has_accepted_license":"1","ddc":["006"],"citation":{"ama":"Sato T, Wojtan C, Thuerey N, Igarashi T, Ando R.

To improve performance, the subsequent narrow band FLIP method (NB‐FLIP) uses a FLIP‐based fluid simulation only near the liquid surface and a traditional grid‐based fluid simulation away from the surface. This spatially‐limited FLIP simulation significantly reduces the number of particles and alleviates a computational bottleneck. In this paper, we extend the NB‐FLIP idea even further, by allowing a simulation to transition between a FLIP‐like fluid simulation and a grid‐based simulation in arbitrary locations, not just near the surface. This approach leads to even more savings in memory and computation, because we can concentrate the particles only in areas where they are needed. More importantly, this new method allows us to seamlessly transition to smooth implicit surface geometry wherever the particle‐based simulation is unnecessary. Consequently, our method leads to a practical algorithm for avoiding the noisy surface artifacts associated with particle‐based liquid simulations, while simultaneously maintaining the benefits of a FLIP simulation in regions of dynamic motion."}]},{"issue":"2","language":[{"iso":"eng"}],"_id":"136","author":[{"full_name":"Suri, Balachandra","last_name":"Suri","first_name":"Balachandra","id":"47A5E706-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Jeffrey","last_name":"Tithof","full_name":"Tithof, Jeffrey"},{"last_name":"Grigoriev","first_name":"Roman","full_name":"Grigoriev, Roman"},{"last_name":"Schatz","first_name":"Michael","full_name":"Schatz, Michael"}],"month":"08","citation":{"mla":"Suri, Balachandra, et al. “Unstable Equilibria and Invariant Manifolds in Quasi-Two-Dimensional Kolmogorov-like Flow.” Physical Review E, vol. 98, no. 2, American Physical Society, 2018, doi:10.1103/PhysRevE.98.023105.","short":"B.

However, extracting the full demographic information from these data is not trivial, and requires inferential methods that account for the diversity of coalescent histories throughout the genome. Here, we evaluate the potential and limitations of one such approach. We reexamine a well-known system of mussel sister species, using the joint site frequency spectrum (jSFS) of synonymousmutations computed either fromexome capture or RNA-seq, in an Approximate Bayesian Computation (ABC) framework. We first assess the best sampling strategy (number of: individuals, loci, and bins in the jSFS), and show that model selection is robust to variation in the number of individuals and loci. In contrast, different binning choices when summarizing the jSFS, strongly affect the results: including classes of low and high frequency shared polymorphisms can more effectively reveal recent migration events. We then take advantage of the flexibility of ABC to compare more realistic models of speciation, including variation in migration rates through time (i.e., periodic connectivity) and across genes (i.e., genome-wide heterogeneity in migration rates). We show that these models were consistently selected as the most probable, suggesting that mussels have experienced a complex history of gene flow during divergence and that the species boundary is semi-permeable. Our work provides a comprehensive evaluation of ABC demographic inference in mussels based on the coding jSFS, and supplies guidelines for employing different sequencing techniques and sampling strategies. We emphasize, perhaps surprisingly, that inferences are less limited by the volume of data, than by the way in which they are analyzed.","lang":"eng"}],"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"},"intvolume":" 2018","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","department":[{"_id":"BeVi"},{"_id":"NiBa"}],"publisher":"PeerJ","publication_status":"published","volume":2018,"type":"journal_article"},{"publication_status":"published","publisher":"MDPI","department":[{"_id":"DaSi"},{"_id":"JiFr"}],"project":[{"call_identifier":"H2020","_id":"261099A6-B435-11E9-9278-68D0E5697425","name":"Tracing Evolution of Auxin Transport and Polarity in Plants","grant_number":"742985"},{"call_identifier":"FWF","grant_number":"I03630","_id":"26538374-B435-11E9-9278-68D0E5697425","name":"Molecular mechanisms of endocytic cargo recognition in plants"}],"quality_controlled":"1","volume":19,"type":"journal_article","scopus_import":"1","date_created":"2018-12-11T11:44:09Z","oa_version":"Published Version","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","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"},"intvolume":" 19","abstract":[{"lang":"eng","text":"The intercellular transport of auxin is driven by PIN-formed (PIN) auxin efflux carriers. PINs are localized at the plasma membrane (PM) and on constitutively recycling endomembrane vesicles. Therefore, PINs can mediate auxin transport either by direct translocation across the PM or by pumping auxin into secretory vesicles (SVs), leading to its secretory release upon fusion with the PM. Which of these two mechanisms dominates is a matter of debate. Here, we addressed the issue with a mathematical modeling approach. We demonstrate that the efficiency of secretory transport depends on SV size, half-life of PINs on the PM, pH, exocytosis frequency and PIN density. 3D structured illumination microscopy (SIM) was used to determine PIN density on the PM. Combining this data with published values of the other parameters, we show that the transport activity of PINs in SVs would have to be at least 1000× greater than on the PM in order to produce a comparable macroscopic auxin transport. If both transport mechanisms operated simultaneously and PINs were equally active on SVs and PM, the contribution of secretion to the total auxin flux would be negligible. In conclusion, while secretory vesicle-mediated transport of auxin is an intriguing and theoretically possible model, it is unlikely to be a major mechanism of auxin transport inplanta."}],"status":"public","date_published":"2018-11-12T00:00:00Z","publist_id":"8042","publication":"International Journal of Molecular Sciences","publication_identifier":{"eissn":["1422-0067"]},"day":"12","date_updated":"2023-09-18T08:09:32Z","title":"Relative contribution of PIN-containing secretory vesicles and plasma membrane PINs to the directed auxin transport: Theoretical estimation","doi":"10.3390/ijms19113566","isi":1,"external_id":{"isi":["000451528500282"]},"oa":1,"article_processing_charge":"No","has_accepted_license":"1","ec_funded":1,"year":"2018","article_type":"original","citation":{"apa":"Hille, S., Akhmanova, M., Glanc, M., Johnson, A.

Promising abstraction techniques usually employ interval methods or template polyhedra. Interval methods account for dense time and guarantee soundness, and there are interval-based tools that overapproximate affine flowpipes. But interval methods impose bounded and rigid shapes, which make refinement expensive and fixpoint detection difficult. Template polyhedra, on the other hand, can be adapted flexibly and can be unbounded, but sound template refinement for unbounded reachability analysis has been implemented only for systems with piecewise constant dynamics. We capitalize on the advantages of both techniques, combining interval arithmetic and template polyhedra, using the former to abstract time and the latter to abstract space. During a CEGAR loop, whenever a spurious error trajectory is found, we compute additional space constraints and split time intervals, and use these space-time interpolants to eliminate the counterexample. Space-time interpolation offers a lazy, flexible framework for increasing precision while guaranteeing soundness, both for error avoidance and fixpoint detection. To the best of out knowledge, this is the first abstraction refinement scheme for the reachability analysis over unbounded and dense time of affine hybrid systems, which is both sound and automatic. We demonstrate the effectiveness of our algorithm with several benchmark examples, which cannot be handled by other tools."}],"publisher":"Springer","publication_status":"published","project":[{"grant_number":"S 11407_N23","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"name":"Moderne Concurrency Paradigms","_id":"25F5A88A-B435-11E9-9278-68D0E5697425","grant_number":"S11402-N23","call_identifier":"FWF"}],"quality_controlled":"1","department":[{"_id":"ToHe"}],"volume":10981,"type":"conference"},{"file_date_updated":"2020-07-14T12:44:53Z","month":"07","file":[{"file_name":"2018_LNCS_Chatterjee.pdf","relation":"main_file","checksum":"1a6ffa4febe8bb8ac28be3adb3eafebc","creator":"dernst","content_type":"application/pdf","access_level":"open_access","date_created":"2018-12-18T08:52:38Z","date_updated":"2020-07-14T12:44:53Z","file_size":675606,"file_id":"5737"}],"author":[{"orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"id":"540c9bbd-f2de-11ec-812d-d04a5be85630","first_name":"Monika H","last_name":"Henzinger","full_name":"Henzinger, Monika H","orcid":"0000-0002-5008-6530"},{"full_name":"Loitzenbauer, Veronika","first_name":"Veronika","last_name":"Loitzenbauer"},{"full_name":"Oraee, Simin","first_name":"Simin","last_name":"Oraee"},{"last_name":"Toman","first_name":"Viktor","id":"3AF3DA7C-F248-11E8-B48F-1D18A9856A87","full_name":"Toman, Viktor","orcid":"0000-0001-9036-063X"}],"citation":{"ista":"Chatterjee K, Henzinger MH, Loitzenbauer V, Oraee S, Toman V. 2018.

We consider graphs and Markov decision processes (MDPs), which are fundamental models for reactive systems. One of the very basic specifications that arise in verification of reactive systems is the strong fairness (aka Streett) objective. Given different types of requests and corresponding grants, the objective requires that for each type, if the request event happens infinitely often, then the corresponding grant event must also happen infinitely often. All ω -regular objectives can be expressed as Streett objectives and hence they are canonical in verification. To handle the state-space explosion, symbolic algorithms are required that operate on a succinct implicit representation of the system rather than explicitly accessing the system. While explicit algorithms for graphs and MDPs with Streett objectives have been widely studied, there has been no improvement of the basic symbolic algorithms. The worst-case numbers of symbolic steps required for the basic symbolic algorithms are as follows: quadratic for graphs and cubic for MDPs. In this work we present the first sub-quadratic symbolic algorithm for graphs with Streett objectives, and our algorithm is sub-quadratic even for MDPs. Based on our algorithmic insights we present an implementation of the new symbolic approach and show that it improves the existing approach on several academic benchmark examples."}],"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"},"intvolume":" 10982","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","project":[{"call_identifier":"FP7","name":"Quantitative Graph Games: Theory and Applications","_id":"2581B60A-B435-11E9-9278-68D0E5697425","grant_number":"279307"},{"grant_number":"ICT15-003","_id":"25892FC0-B435-11E9-9278-68D0E5697425","name":"Efficient Algorithms for Computer Aided Verification"},{"grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425","name":"Rigorous Systems Engineering","call_identifier":"FWF"},{"grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program","call_identifier":"H2020"}],"quality_controlled":"1","department":[{"_id":"KrCh"}],"publisher":"Springer","publication_status":"published","volume":10982,"type":"conference"},{"month":"06","oa_version":"Preprint","author":[{"last_name":"Fortuin","first_name":"Vincent","full_name":"Fortuin, Vincent"},{"full_name":"Hüser, Matthias","first_name":"Matthias","last_name":"Hüser"},{"full_name":"Locatello, Francesco","orcid":"0000-0002-4850-0683","last_name":"Locatello","first_name":"Francesco","id":"26cfd52f-2483-11ee-8040-88983bcc06d4"},{"last_name":"Strathmann","first_name":"Heiko","full_name":"Strathmann, Heiko"},{"first_name":"Gunnar","last_name":"Rätsch","full_name":"Rätsch, Gunnar"}],"date_created":"2023-08-22T14:12:48Z","citation":{"apa":"Fortuin, V., Hüser, M., Locatello, F., Strathmann, H., & Rätsch, G.

Since human\r\ncognition is not optimized to work well in high-dimensional spaces, these areas\r\ncould benefit from interpretable low-dimensional representations. However, most\r\nrepresentation learning algorithms for time series data are difficult to\r\ninterpret. This is due to non-intuitive mappings from data features to salient\r\nproperties of the representation and non-smoothness over time. To address this\r\nproblem, we propose a new representation learning framework building on ideas\r\nfrom interpretable discrete dimensionality reduction and deep generative\r\nmodeling. This framework allows us to learn discrete representations of time\r\nseries, which give rise to smooth and interpretable embeddings with superior\r\nclustering performance. We introduce a new way to overcome the\r\nnon-differentiability in discrete representation learning and present a\r\ngradient-based version of the traditional self-organizing map algorithm that is\r\nmore performant than the original. Furthermore, to allow for a probabilistic\r\ninterpretation of our method, we integrate a Markov model in the representation\r\nspace. This model uncovers the temporal transition structure, improves\r\nclustering performance even further and provides additional explanatory\r\ninsights as well as a natural representation of uncertainty. We evaluate our\r\nmodel in terms of clustering performance and interpretability on static\r\n(Fashion-)MNIST data, a time series of linearly interpolated (Fashion-)MNIST\r\nimages, a chaotic Lorenz attractor system with two macro states, as well as on\r\na challenging real world medical time series application on the eICU data set.\r\nOur learned representations compare favorably with competitor methods and\r\nfacilitate downstream tasks on the real world data.","lang":"eng"}],"_id":"14198","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","external_id":{"arxiv":["1806.02199"]},"title":"SOM-VAE: Interpretable discrete representation learning on time series","department":[{"_id":"FrLo"}],"date_updated":"2023-09-13T06:35:12Z","publication_status":"published","day":"06","main_file_link":[{"url":"https://arxiv.org/abs/1806.02199","open_access":"1"}],"year":"2018","conference":{"name":"ICLR: International Conference on Learning Representations","location":"New Orleans, LA, United States","end_date":"2019-05-09","start_date":"2019-05-06"},"article_processing_charge":"No","oa":1,"type":"conference"},{"page":"449 - 467","_id":"142","language":[{"iso":"eng"}],"acknowledgement":"Austrian Science Fund FWF: S11402-N23, S11405-N23, Z211-N32","author":[{"orcid":"0000-0002-3066-6941","full_name":"Kong, Hui","last_name":"Kong","first_name":"Hui","id":"3BDE25AA-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Bartocci, Ezio","first_name":"Ezio","last_name":"Bartocci"},{"full_name":"Henzinger, Thomas A","orcid":"0000−0002−2985−7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","first_name":"Thomas A"}],"file":[{"file_size":5591566,"file_id":"5718","access_level":"open_access","date_updated":"2020-07-14T12:44:53Z","date_created":"2018-12-17T15:57:06Z","content_type":"application/pdf","file_name":"2018_LNCS_Kong.pdf","relation":"main_file","checksum":"fd95e8026deacef3dc752a733bb9355f","creator":"dernst"}],"file_date_updated":"2020-07-14T12:44:53Z","month":"07","ddc":["000"],"citation":{"ama":"Kong H, Bartocci E, Henzinger TA.

The common approach to tackle this problem is to perform a numerical integration over a given time horizon based on Taylor expansion and interval arithmetic. However, this method results to be very conservative when there is a large difference in speed between trajectories as time progresses. In this paper, we propose to use combinations of barrier functions, which we call piecewise barrier tube (PBT), to over-approximate flowpipe. The basic idea of PBT is that for each segment of a flowpipe, a coarse box which is big enough to contain the segment is constructed using sampled simulation and then in the box we compute by linear programming a set of barrier functions (called barrier tube or BT for short) which work together to form a tube surrounding the flowpipe. The benefit of using PBT is that (1) BT is independent of time and hence can avoid being stretched and deformed by time; and (2) a small number of BTs can form a tight over-approximation for the flowpipe, which means that the computation required to decide whether the BTs intersect the unsafe set can be reduced significantly. We implemented a prototype called PBTS in C++. Experiments on some benchmark systems show that our approach is effective.","lang":"eng"}],"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"},"intvolume":" 10981","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa_version":"Published Version","date_created":"2018-12-11T11:44:51Z","scopus_import":"1","alternative_title":["LNCS"],"type":"conference","volume":10981,"quality_controlled":"1","project":[{"call_identifier":"FWF","grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425","name":"Rigorous Systems Engineering"},{"call_identifier":"FWF","_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"The Wittgenstein Prize","grant_number":"Z211"}],"department":[{"_id":"ToHe"}],"publisher":"Springer","publication_status":"published"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 84","abstract":[{"lang":"eng","text":"Variational inference is a popular technique to approximate a possibly\r\nintractable Bayesian posterior with a more tractable one.

While the former targets the optimization by moving along coordinates, the latter considers a generalized notion of directions. Exploiting the connection between the two algorithms, we present a unified analysis of both, providing affine invariant sublinear O(1/t) rates on smooth objectives and linear convergence on strongly convex objectives. As a byproduct of our affine invariant analysis of matching pursuit, our rates for steepest coordinate descent are the tightest known. Furthermore, we show the first accelerated convergence rate O(1/t2) for matching pursuit and steepest coordinate descent on convex objectives."}],"publisher":"ML Research Press","publication_status":"published","quality_controlled":"1","department":[{"_id":"FrLo"}],"volume":80,"type":"conference","main_file_link":[{"url":"https://arxiv.org/abs/1803.09539","open_access":"1"}]}]
