We consider two types of path constraints: (i) a quantitative constraint defines the set of paths where the payoff is at least a given threshold λ1ε(0,1]; and (ii) a qualitative constraint which is a special case of the quantitative constraint with λ1=1. We consider the computation of the almost-sure winning set, where the controller needs to ensure that the path constraint is satisfied with probability 1. Our main results for qualitative path constraints are as follows: (i) the problem of deciding the existence of a finite-memory controller is EXPTIME-complete; and (ii) the problem of deciding the existence of an infinite-memory controller is undecidable. For quantitative path constraints we show that the problem of deciding the existence of a finite-memory controller is undecidable. We also present a prototype implementation of our EXPTIME algorithm and experimental results on several examples."}],"citation":{"ama":"Chatterjee K, Chmelik M.

Better understanding of its functional diversity and complexity has led to an increased demand for specificity in experimental procedures and manipulations. In view of the complex 3D structure of the hippocampal region, precisely positioned experimental approaches require a fine-grained architectural description that is available and readable to experimentalists lacking detailed anatomical experience. In this paper, we provide the first cyto- and chemoarchitectural description of the hippocampal formation and parahippocampal region in the rat at high resolution and in the three standard sectional planes: coronal, horizontal and sagittal. The atlas uses a series of adjacent sections stained for neurons and for a number of chemical marker substances, particularly parvalbumin and calbindin. All the borders defined in one plane have been cross-checked against their counterparts in the other two planes. The entire dataset will be made available as a web-based interactive application through the Rodent Brain WorkBench (http://www.rbwb.org) which, together with this paper, provides a unique atlas resource.","lang":"eng"}],"scopus_import":"1","citation":{"ama":"Boccara CN, Kjønigsen L, Hammer I, Bjaalie J, Leergaard T, Witter M.

To date, however, a molecular evaluation of the current systematic treatments has not been carried out. The aim of the present study is to infer phylogenetic relationships among its subordinate taxa by using plastidial rps16 intron and nuclear internal transcribed spacer (ITS) DNA sequences; and evaluate the phylogenetic placement of the genus Petrocoptis within the family Caryophyllaceae. The monophyly of Petrocoptis is supported by both ITS and rps16 intron sequence analyses. Furthermore, time estimates using BEAST analyses indicate a Middle to Late Miocene diversification (10.59 Myr, 6.44–15.26 Myr highest posterior densities [HPD], for ITS; 14.30 Myr, 8.61–21.00 Myr HPD, for rps16 intron).","lang":"eng"}],"scopus_import":"1","publisher":"Springer"},{"citation":{"ama":"Kremer A, Lippens S, Bartunkova S, et al.

Over the last 80 years EM has vastly increased our understanding of the complex cellular structures that underlie the diverse functions that cells need to maintain life. One drawback that has been difficult to overcome was the inherent lack of volume information, mainly due to the limit on the thickness of sections that could be viewed in a transmission electron microscope (TEM). For many years scientists struggled to achieve three-dimensional (3D) EM using serial section reconstructions, TEM tomography, and scanning EM (SEM) techniques such as freeze-fracture. Although each technique yielded some special information, they required a significant amount of time and specialist expertise to obtain even a very small 3D EM dataset. Almost 20 years ago scientists began to exploit SEMs to image blocks of embedded tissues and perform serial sectioning of these tissues inside the SEM chamber. Using first focused ion beams (FIB) and subsequently robotic ultramicrotomes (serial block-face, SBF-SEM) microscopists were able to collect large volumes of 3D EM information at resolutions that could address many important biological questions, and do so in an efficient manner. We present here some examples of 3D EM taken from the many diverse specimens that have been imaged in our core facility.

Nevertheless, positional information has neither been defined mathematically nor quantified in a principled way. Here we provide an information-theoretic definition in the context of developmental gene expression patterns and examine the features of expression patterns that affect positional information quantitatively. We connect positional information with the concept of positional error and develop tools to directly measure information and error from experimental data. We illustrate our framework for the case of gap gene expression patterns in the early Drosophila embryo and show how information that is distributed among only four genes is sufficient to determine developmental fates with nearly single-cell resolution. Our approach can be generalized to a variety of different model systems; procedures and examples are discussed in detail.

Can such spatial coupling be of benefit for conveying signals subject to gene regulatory noise? Here we extend our information-theoretic framework for gene regulation to spatially extended systems. As an example, we consider a lattice of nuclei responding to a concentration field of a transcriptional regulator (the &quot;input&quot;) by expressing a single diffusible target gene. When input concentrations are low, diffusive coupling markedly improves information transmission; optimal gene activation functions also systematically change. A qualitatively new regulatory strategy emerges where individual cells respond to the input in a nearly step-like fashion that is subsequently averaged out by strong diffusion. While motivated by early patterning events in the Drosophila embryo, our framework is generically applicable to spatially coupled stochastic gene expression models."}],"oa_version":"Preprint","oa":1,"publication_status":"published","doi":"10.1103/PhysRevE.91.062710","intvolume":"        91","language":[{"iso":"eng"}],"author":[{"orcid":"0000-0002-1287-3779","last_name":"Sokolowski","first_name":"Thomas R","full_name":"Sokolowski, Thomas R","id":"3E999752-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0002-6699-1455","last_name":"Tkacik","first_name":"Gasper","full_name":"Tkacik, Gasper","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87"}],"date_created":"2018-12-11T11:54:49Z","year":"2015","corr_author":"1","publication":"Physical Review E Statistical Nonlinear and Soft Matter Physics","day":"15","_id":"1940","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","department":[{"_id":"GaTk"}],"issue":"6"},{"status":"public","type":"journal_article","publisher":"Elsevier","oa_version":"None","citation":{"chicago":"Rakusová, Hana, Matyas Fendrych, and Jiří Friml. “Intracellular Trafficking and PIN-Mediated Cell Polarity during Tropic Responses in Plants.” <i>Current Opinion in Plant Biology</i>.

Inflammatory processes are often associated with an increased production of serotonin, which operates by activating specific receptors. However, the functional role of serotonin receptors in regulation of dendritic cell functions is poorly understood. Here, we demonstrate that expression of serotonin receptor 5-HT7 (5-HT7TR) as well as its downstream effector Cdc42 is upregulated in dendritic cells upon maturation. Although dendritic cell maturation was independent of 5-HT7TR, receptor stimulation affected dendritic cell morphology through Cdc42-mediated signaling. In addition, basal activity of 5-HT7TR was required for the proper expression of the chemokine receptor CCR7, which is a key factor that controls dendritic cell migration. Consistent with this, we observed that 5-HT7TR enhances chemotactic motility of dendritic cells in vitro by modulating their directionality and migration velocity. Accordingly, migration of dendritic cells in murine colon explants was abolished after pharmacological receptor inhibition. Our results indicate that there is a crucial role for 5-HT7TR-Cdc42-mediated signaling in the regulation of dendritic cell morphology and motility, suggesting that 5-HT7TR could be a new target for treatment of a variety of inflammatory and immune disorders."}],"scopus_import":"1","citation":{"ieee":"K.

We study the most fundamental objective for concurrent games, namely, mean-payoff or limit-average objective, where a reward is associated to each transition, and the goal of player 1 is to maximize the long-run average of the rewards, and the objective of player 2 is strictly the opposite (i.e., the games are zero-sum). The path constraint for player 1 could be qualitative, i.e., the mean-payoff is the maximal reward, or arbitrarily close to it; or quantitative, i.e., a given threshold between the minimal and maximal reward. We consider the computation of the almost-sure (resp. positive) winning sets, where player 1 can ensure that the path constraint is satisfied with probability 1 (resp. positive probability). Almost-sure winning with qualitative constraint exactly corresponds to the question of whether there exists a strategy to ensure that the payoff is the maximal reward of the game. Our main results for qualitative path constraints are as follows: (1) we establish qualitative determinacy results that show that for every state either player 1 has a strategy to ensure almost-sure (resp. positive) winning against all player-2 strategies, or player 2 has a spoiling strategy to falsify almost-sure (resp. positive) winning against all player-1 strategies; (2) we present optimal strategy complexity results that precisely characterize the classes of strategies required for almost-sure and positive winning for both players; and (3) we present quadratic time algorithms to compute the almost-sure and the positive winning sets, matching the best known bound of the algorithms for much simpler problems (such as reachability objectives). For quantitative constraints we show that a polynomial time solution for the almost-sure or the positive winning set would imply a solution to a long-standing open problem (of solving the value problem of turn-based deterministic mean-payoff games) that is not known to be solvable in polynomial time.","lang":"eng"}],"status":"public","type":"journal_article","related_material":{"record":[{"id":"5403","relation":"earlier_version","status":"public"}]}},{"day":"22","publication":"Cell","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","_id":"532","issue":"3","department":[{"_id":"JiFr"}],"page":"670 - 683","language":[{"iso":"eng"}],"author":[{"last_name":"Li","first_name":"Wenyang","full_name":"Li, Wenyang"},{"full_name":"Ma, Mengdi","last_name":"Ma","first_name":"Mengdi"},{"last_name":"Feng","first_name":"Ying","full_name":"Feng, Ying"},{"first_name":"Hongjiang","last_name":"Li","orcid":"0000-0001-5039-9660","id":"33CA54A6-F248-11E8-B48F-1D18A9856A87","full_name":"Li, Hongjiang"},{"first_name":"Yichuan","last_name":"Wang","full_name":"Wang, Yichuan"},{"first_name":"Yutong","last_name":"Ma","full_name":"Ma, Yutong"},{"first_name":"Mingzhe","last_name":"Li","full_name":"Li, Mingzhe"},{"first_name":"Fengying","last_name":"An","full_name":"An, Fengying"},{"full_name":"Guo, Hongwei","first_name":"Hongwei","last_name":"Guo"}],"publication_status":"published","doi":"10.1016/j.cell.2015.09.037","intvolume":"       163","year":"2015","date_created":"2018-12-11T11:47:00Z","type":"journal_article","status":"public","citation":{"ama":"Li W, Ma M, Feng Y, et al.

Previous studies uncovered EIN2 as an essential signal transducer linking ethylene perception on ER to transcriptional regulation in the nucleus through a “cleave and shuttle” model. In this study, we report another mechanism of EIN2-mediated ethylene signaling, whereby EIN2 imposes the translational repression of EBF1 and EBF2 mRNA. We find that the EBF1/2 3′ UTRs mediate EIN2-directed translational repression and identify multiple poly-uridylates (PolyU) motifs as functional cis elements of 3′ UTRs. Furthermore, we demonstrate that ethylene induces EIN2 to associate with 3′ UTRs and target EBF1/2 mRNA to cytoplasmic processing-body (P-body) through interacting with multiple P-body factors, including EIN5 and PABs. Our study illustrates translational regulation as a key step in ethylene signaling and presents mRNA 3′ UTR functioning as a “signal transducer” to sense and relay cellular signaling in plants.","lang":"eng"}],"oa_version":"None","publisher":"Cell Press","external_id":{"isi":["000364828900020"]},"date_updated":"2025-09-23T08:40:43Z","quality_controlled":"1","month":"10","volume":163,"publist_id":"7285","title":"EIN2-directed translational regulation of ethylene signaling in arabidopsis","article_processing_charge":"No","date_published":"2015-10-22T00:00:00Z","isi":1},{"oa":1,"publication_status":"published","doi":"10.15479/AT:IST-2015-319-v1-1","month":"02","file":[{"date_updated":"2020-07-14T12:46:52Z","content_type":"application/pdf","relation":"main_file","file_size":1089651,"file_id":"5482","date_created":"2018-12-12T11:53:21Z","access_level":"open_access","file_name":"IST-2015-319-v1+1_long.pdf","checksum":"62c6ea01e342553dcafb88a070fb1ad5","creator":"system"}],"file_date_updated":"2020-07-14T12:46:52Z","pubrep_id":"319","language":[{"iso":"eng"}],"ddc":["000"],"author":[{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee"},{"full_name":"Ibsen-Jensen, Rasmus","id":"3B699956-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-4783-0389","first_name":"Rasmus","last_name":"Ibsen-Jensen"},{"orcid":"0000-0002-8943-0722","first_name":"Andreas","last_name":"Pavlogiannis","full_name":"Pavlogiannis, Andreas","id":"49704004-F248-11E8-B48F-1D18A9856A87"}],"date_updated":"2025-09-23T08:47:23Z","title":"Faster algorithms for quantitative verification in constant treewidth graphs","date_created":"2018-12-12T11:39:17Z","date_published":"2015-02-10T00:00:00Z","alternative_title":["IST Austria Technical Report"],"year":"2015","type":"technical_report","publication_identifier":{"issn":["2664-1690"]},"status":"public","related_material":{"record":[{"id":"5437","relation":"later_version","status":"public"},{"status":"public","id":"1607","relation":"later_version"}]},"day":"10","page":"31","publisher":"IST Austria","has_accepted_license":"1","_id":"5430","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"KrCh"}],"citation":{"ama":"Chatterjee K, Ibsen-Jensen R, Pavlogiannis A. <i>Faster Algorithms for Quantitative Verification in Constant Treewidth Graphs</i>.

The algorithmic problem given a graph and a quantitative property asks to compute the optimal value (the infimum value over all traces) from every node of the graph. We consider graphs with constant treewidth, and it is well-known that the control-flow graphs of most programs have constant treewidth. Let n denote the number of nodes of a graph, m the number of edges (for constant treewidth graphs m = O ( n ) ) and W the largest absolute value of the weights. Our main theoretical results are as follows. First, for constant treewidth graphs we present an algorithm that approximates the mean-payoff value within a mul- tiplicative factor of ∊ in time O ( n · log( n/∊ )) and linear space, as compared to the classical algorithms that require quadratic time. Second, for the ratio property we present an algorithm that for constant treewidth graphs works in time O ( n · log( | a · b · n | )) = O ( n · log( n · W )) , when the output is a b , as compared to the previously best known algorithm with running time O ( n 2 · log( n · W )) . Third, for the minimum initial credit problem we show that (i) for general graphs the problem can be solved in O ( n 2 · m ) time and the associated decision problem can be solved in O ( n · m ) time, improving the previous known O ( n 3 · m · log( n · W )) and O ( n 2 · m ) bounds, respectively; and (ii) for constant treewidth graphs we present an algorithm that requires O ( n · log n ) time, improving the previous known O ( n 4 · log( n · W )) bound.

The structure of the population affects the outcome of the evolutionary process. Evolutionary graph theory is a powerful approach to study this phenomenon. There are two graphs. The interaction graph specifies who interacts with whom in the context of evolution.The replacement graph specifies who competes with whom for reproduction. \r\nThe vertices of the two graphs are the same, and each vertex corresponds to an individual of the population. A key quantity is the fixation probability of a new mutant. It is defined as the probability that a newly introduced mutant (on a single vertex) generates a lineage of offspring which eventually takes over the entire population of resident individuals. The basic computational questions are as follows: (i) the qualitative question asks whether the fixation probability is positive; and (ii) the quantitative approximation question asks for an approximation of the fixation probability. \r\nOur main results are:\r\n(1) We show that the qualitative question is NP-complete and the quantitative approximation question is #P-hard in the special case when the interaction and the replacement graphs coincide and even with the restriction that the resident individuals do not reproduce (which corresponds to an invading population taking over an empty structure).\r\n(2) We show that in general the qualitative question is PSPACE-complete and the quantitative approximation question is PSPACE-hard and can be solved in exponential time.\r\n"}],"department":[{"_id":"KrCh"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"5432","status":"public","publication_identifier":{"issn":["2664-1690"]},"type":"technical_report","day":"19","related_material":{"record":[{"status":"public","relation":"earlier_version","id":"5421"},{"status":"public","id":"5440","relation":"later_version"}]}}]
