Although much is \r\nknown about the gene regulatory programs and signaling pathways that operate at \r\nthe cellular scale, it has remained unclear how the macroscopic features of branched \r\norgans, including their size, network topology and spatial patterning, are encoded. \r\nLately, it has been proposed that, these features can be explained quantitatively in \r\nseveral organs within a single unifying framework. Based on large-\r\nscale organ recon\r\n-\r\nstructions and cell lineage tracing, it has been argued that morphogenesis follows \r\nfrom the collective dynamics of sublineage- \r\nrestricted self- \r\nrenewing progenitor cells, \r\nlocalized at ductal tips, that act cooperatively to drive a serial process of ductal elon\r\n-\r\ngation and stochastic tip bifurcation. By correlating differentiation or cell cycle exit \r\nwith proximity to maturing ducts, this dynamic results in the specification of a com-\r\nplex network of defined density and statistical organization. These results suggest \r\nthat, for several mammalian tissues, branched epithelial structures develop as a self- \r\norganized process, reliant upon a strikingly simple, but generic, set of local rules, \r\nwithout recourse to a rigid and deterministic sequence of genetically programmed \r\nevents. Here, we review the basis of these findings and discuss their implications.","lang":"eng"}],"type":"journal_article","citation":{"short":"E.B. Hannezo, B.D.

In particular, we show that, if the symmetry of a free quantum particle corresponds to a Lie group G, in the presence of a many-body environment this particle can be described by a deformed group, Gq. Crucially, the single deformation parameter, q, contains all the information about the many-particle interactions in the system. We exemplify our approach by considering a quantum rotor interacting with a bath of bosons, and demonstrate that extracting the value of q from closed-form solutions in the perturbative regime allows one to predict the behavior of the system for arbitrary values of the impurity-bath coupling strength, in good agreement with nonperturbative calculations. Furthermore, the value of the deformation parameter allows one to predict at which coupling strengths rotor-bath interactions result in a formation of a stable quasiparticle. The approach based on quantum groups does not only allow for a drastic simplification of impurity problems, but also provides valuable insights into hidden symmetries of interacting many-particle systems."}],"citation":{"short":"E.

Imaging data provide quantitative information about biological systems; however, mechanisms causing spatial patterning often remain elusive. In recent years, spatio-temporal mathematical modelling has helped to overcome this problem. Yet, outliers and structured noise limit modelling of whole imaging data, and models often consider spatial summary statistics. Here, we introduce an integrated data-driven modelling approach that can cope with measurement artefacts and whole imaging data. Our approach combines mechanistic models of the biological processes with robust statistical models of the measurement process. The parameters of the integrated model are calibrated using a maximum-likelihood approach. We used this integrated modelling approach to study in vivo gradients of the chemokine (C-C motif) ligand 21 (CCL21). CCL21 gradients guide dendritic cells and are important in the adaptive immune response. Using artificial data, we verified that the integrated modelling approach provides reliable parameter estimates in the presence of measurement noise and that bias and variance of these estimates are reduced compared to conventional approaches. The application to experimental data allowed the parametrization and subsequent refinement of the model using additional mechanisms. Among other results, model-based hypothesis testing predicted lymphatic vessel-dependent concentration of heparan sulfate, the binding partner of CCL21. The selected model provided an accurate description of the experimental data and was partially validated using published data. Our findings demonstrate that integrated statistical modelling of whole imaging data is computationally feasible and can provide novel biological insights."}],"quality_controlled":"1","publisher":"Royal Society Publishing","volume":15,"department":[{"_id":"MiSi"}]},{"doi":"10.1098/rsos.181286","day":"12","file":[{"file_size":646732,"creator":"dernst","file_name":"2018_RoyalSocOS_Corominas.pdf","date_created":"2019-02-05T14:38:09Z","access_level":"open_access","file_id":"5924","date_updated":"2020-07-14T12:47:13Z","relation":"main_file","content_type":"application/pdf","checksum":"9664d4417f6b792242e31eea77ce9501"}],"oa":1,"intvolume":" 5","date_published":"2018-12-12T00:00:00Z","article_number":"181286","publication_identifier":{"issn":["2054-5703"]},"year":"2018","acknowledgement":"This work was supported by the James McDonnell Foundation (B.C-M., S.V. and R.S.)","article_type":"original","publication":"Royal Society Open Science","isi":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","ddc":["570"],"oa_version":"Published Version","author":[{"id":"43BE2298-F248-11E8-B48F-1D18A9856A87","last_name":"Corominas-Murtra","full_name":"Corominas-Murtra, Bernat","orcid":"0000-0001-9806-5643","first_name":"Bernat"},{"first_name":"Martí Sànchez","full_name":"Fibla, Martí Sànchez","last_name":"Fibla"},{"first_name":"Sergi","full_name":"Valverde, Sergi","last_name":"Valverde"},{"last_name":"Solé","full_name":"Solé, Ricard","first_name":"Ricard"}],"title":"Chromatic transitions in the emergence of syntax networks","date_updated":"2023-10-18T06:41:12Z","language":[{"iso":"eng"}],"status":"public","file_date_updated":"2020-07-14T12:47:13Z","has_accepted_license":"1","article_processing_charge":"No","pmid":1,"type":"journal_article","abstract":[{"text":"The emergence of syntax during childhood is a remarkable example of how complex correlations unfold in nonlinear ways through development. In particular, rapid transitions seem to occur as children reach the age of two, which seems to separate a two-word, tree-like network of syntactic relations among words from the scale-free graphs associated with the adult, complex grammar. Here, we explore the evolution of syntax networks through language acquisition using the chromatic number, which captures the transition and provides a natural link to standard theories on syntactic structures. The data analysis is compared to a null model of network growth dynamics which is shown to display non-trivial and sensible differences. At a more general level, we observe that the chromatic classes define independent regions of the graph, and thus, can be interpreted as the footprints of incompatibility relations, somewhat as opposed to modularity considerations.","lang":"eng"}],"citation":{"short":"B.

Open-ended evolution (OEE) refers to the unbounded increase in complexity that seems to characterize evolution on multiple scales. This property seems to be a characteristic feature of biological and technological evolution and is strongly tied to the generative potential associated with combinatorics, which allows the system to grow and expand their available state spaces. Interestingly, many complex systems presumably displaying OEE, from language to proteins, share a common statistical property: the presence of Zipf's Law. Given an inventory of basic items (such as words or protein domains) required to build more complex structures (sentences or proteins) Zipf's Law tells us that most of these elements are rare whereas a few of them are extremely common. Using algorithmic information theory, in this paper we provide a fundamental definition for open-endedness, which can be understood as postulates. Its statistical counterpart, based on standard Shannon information theory, has the structure of a variational problem which is shown to lead to Zipf's Law as the expected consequence of an evolutionary process displaying OEE. We further explore the problem of information conservation through an OEE process and we conclude that statistical information (standard Shannon information) is not conserved, resulting in the paradoxical situation in which the increase of information content has the effect of erasing itself. We prove that this paradox is solved if we consider non-statistical forms of information. This last result implies that standard information theory may not be a suitable theoretical framework to explore the persistence and increase of the information content in OEE systems.","lang":"eng"}],"citation":{"ieee":"B.

In this paper, we propose a formal framework for specifying and monitoring rich temporal properties of real-valued signals. We introduce signal first-order logic (SFO) as a specification language that combines first-order logic with linear-real arithmetic and unary function symbols interpreted as piecewise-linear signals. We first show that while the satisfiability problem for SFO is undecidable, its membership and monitoring problems are decidable. We develop an offline monitoring procedure for SFO that has polynomial complexity in the size of the input trace and the specification, for a fixed number of quantifiers and function symbols. We show that the algorithm has computation time linear in the size of the input trace for the important fragment of bounded-response specifications interpreted over input traces with finite variability. We can use our results to extend signal temporal logic with first-order quantifiers over time and value parameters, while preserving its efficient monitoring. We finally demonstrate the practical appeal of our logic through a case study in the micro-electronics domain."}],"has_accepted_license":"1","article_processing_charge":"No","file_date_updated":"2020-07-14T12:47:13Z","language":[{"iso":"eng"}],"status":"public","page":"1-10","date_updated":"2025-07-10T11:53:06Z","author":[{"first_name":"Alexey","last_name":"Bakhirkin","full_name":"Bakhirkin, Alexey"},{"first_name":"Thomas","orcid":"0000-0001-5199-3143","last_name":"Ferrere","full_name":"Ferrere, Thomas","id":"40960E6E-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000−0002−2985−7724","last_name":"Henzinger","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A"},{"last_name":"Nickovicl","full_name":"Nickovicl, Deian","first_name":"Deian"}],"title":"Keynote: The first-order logic of signals","oa_version":"Published Version","ddc":["000"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"call_identifier":"FWF","grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425","name":"Rigorous Systems Engineering"},{"call_identifier":"FWF","grant_number":"Z211","_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"Formal methods for the design and analysis of complex systems"}],"isi":1,"publication":"2018 International Conference on Embedded Software","year":"2018","publication_identifier":{"isbn":["9781538655603"]},"date_published":"2018-09-30T00:00:00Z","file":[{"creator":"dernst","file_size":338006,"file_name":"2018_EMSOFT_Bakhirkin.pdf","date_created":"2020-05-14T16:01:29Z","access_level":"open_access","date_updated":"2020-07-14T12:47:13Z","file_id":"7839","content_type":"application/pdf","checksum":"234a33ad9055b3458fcdda6af251b33a","relation":"main_file"}],"oa":1,"doi":"10.1109/emsoft.2018.8537203","day":"30"},{"volume":37,"department":[{"_id":"UlWa"}],"publisher":"SAGE Publications","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1712.01341"}],"citation":{"short":"S.

The loop closure detection is one of the key points in simultaneous localization and mapping (SLAM) methods, especially in homogeneous environments with difficult scenes recognitions. The proposed approach is generic and could be coupled with conventional SLAM algorithms to reliably reduce their computing burden, thus improving the localization and mapping processes in the most challenging environments such as unexplored underwater extents. To prove that a robot performed a loop whatever the uncertainties in its evolution, we employ the notion of topological degree that originates in the field of differential topology. We show that a verification tool based on the topological degree is an optimal method for proving robot loops. This is demonstrated both on datasets from real missions involving autonomous underwater vehicles and by a mathematical discussion.","lang":"eng"}],"quality_controlled":"1","_id":"5960","month":"10","issue":"12","scopus_import":"1","publication_status":"published","date_created":"2019-02-13T09:36:20Z","external_id":{"arxiv":["1712.01341"],"isi":["000456881100004"]},"isi":1,"publication":"The International Journal of Robotics Research","arxiv":1,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa":1,"doi":"10.1177/0278364918808367","day":"24","date_published":"2018-10-24T00:00:00Z","intvolume":" 37","year":"2018","publication_identifier":{"eissn":["1741-3176"],"issn":["0278-3649"]},"title":"Proving the existence of loops in robot trajectories","author":[{"full_name":"Rohou, Simon","last_name":"Rohou","first_name":"Simon"},{"first_name":"Peter","id":"473294AE-F248-11E8-B48F-1D18A9856A87","full_name":"Franek, Peter","last_name":"Franek","orcid":"0000-0001-8878-8397"},{"full_name":"Aubry, Clément","last_name":"Aubry","first_name":"Clément"},{"first_name":"Luc","last_name":"Jaulin","full_name":"Jaulin, Luc"}],"date_updated":"2023-09-19T10:41:59Z","page":"1500-1516","status":"public","language":[{"iso":"eng"}],"article_processing_charge":"No","oa_version":"Preprint"},{"conference":{"end_date":"2018-07-27","location":"Egham, United Kingdom","name":"PODC: Principles of Distributed Computing","start_date":"2018-07-23"},"external_id":{"isi":["000458186900063"]},"publication_status":"published","date_created":"2019-02-13T09:48:55Z","oa_version":"None","language":[{"iso":"eng"}],"status":"public","month":"07","scopus_import":"1","article_processing_charge":"No","author":[{"first_name":"Dan-Adrian","orcid":"0000-0003-3650-940X","last_name":"Alistarh","full_name":"Alistarh, Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87"}],"title":"A brief tutorial on distributed and concurrent machine learning","_id":"5961","page":"487-488","date_updated":"2025-06-03T11:56:33Z","publication_identifier":{"isbn":["9781450357951"]},"year":"2018","day":"27","doi":"10.1145/3212734.3212798","abstract":[{"text":"The area of machine learning has made considerable progress over the past decade, enabled by the widespread availability of large datasets, as well as by improved algorithms and models.

Given the recent practical focus on distributed machine learning, significant work has been dedicated to the convergence properties of this algorithm under the inconsistent and noisy updates arising from execution in a distributed environment. However, surprisingly, the convergence properties of this classic algorithm in the standard shared-memory model are still not well-understood. In this work, we address this gap, and provide new convergence bounds for lock-free concurrent stochastic gradient descent, executing in the classic asynchronous shared memory model, against a strong adaptive adversary. Our results give improved upper and lower bounds on the \"price of asynchrony'' when executing the fundamental SGD algorithm in a concurrent setting. They show that this classic optimization tool can converge faster and with a wider range of parameters than previously known under asynchronous iterations. At the same time, we exhibit a fundamental trade-off between the maximum delay in the system and the rate at which SGD can converge, which governs the set of parameters under which this algorithm can still work efficiently."}],"quality_controlled":"1","publisher":"ACM","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1803.08841"}],"department":[{"_id":"DaAl"}],"conference":{"start_date":"2018-07-23","name":"PODC: Principles of Distributed Computing","location":"Egham, United Kingdom","end_date":"2018-07-27"},"external_id":{"arxiv":["1803.08841"],"isi":["000458186900022"]},"publication_status":"published","date_created":"2019-02-13T09:58:58Z","month":"07","scopus_import":"1","_id":"5962"},{"month":"07","scopus_import":"1","_id":"5963","conference":{"location":"Egham, United Kingdom","name":"PODC: Principles of Distributed Computing","start_date":"2018-07-23","end_date":"2018-07-27"},"external_id":{"isi":["000458186900048"],"arxiv":["1808.04155"]},"publication_status":"published","date_created":"2019-02-13T10:03:25Z","publisher":"ACM","main_file_link":[{"url":"https://arxiv.org/abs/1808.04155","open_access":"1"}],"department":[{"_id":"DaAl"}],"abstract":[{"text":"There has been significant progress in understanding the parallelism inherent to iterative sequential algorithms: for many classic algorithms, the depth of the dependence structure is now well understood, and scheduling techniques have been developed to exploit this shallow dependence structure for efficient parallel implementations. A related, applied research strand has studied methods by which certain iterative task-based algorithms can be efficiently parallelized via relaxed concurrent priority schedulers. These allow for high concurrency when inserting and removing tasks, at the cost of executing superfluous work due to the relaxed semantics of the scheduler. In this work, we take a step towards unifying these two research directions, by showing that there exists a family of relaxed priority schedulers that can efficiently and deterministically execute classic iterative algorithms such as greedy maximal independent set (MIS) and matching. Our primary result shows that, given a randomized scheduler with an expected relaxation factor of k in terms of the maximum allowed priority inversions on a task, and any graph on n vertices, the scheduler is able to execute greedy MIS with only an additive factor of \\poly(k) expected additional iterations compared to an exact (but not scalable) scheduler. This counter-intuitive result demonstrates that the overhead of relaxation when computing MIS is not dependent on the input size or structure of the input graph. Experimental results show that this overhead can be clearly offset by the gain in performance due to the highly scalable scheduler. In sum, we present an efficient method to deterministically parallelize iterative sequential algorithms, with provable runtime guarantees in terms of the number of executed tasks to completion.","lang":"eng"}],"type":"conference","citation":{"short":"D.-A.

While the standard solution to such conflicts is to immediately abort one of the transactions, some practical systems consider the alternative of delaying conflict resolution for a short interval, which may allow one of the transactions to commit. The challenge in the transactional conflict problem is to choose the optimal length of this delay interval so as to minimize the overall running time penalty for the conflicting transactions. In this paper, we propose a family of optimal online algorithms for the transactional conflict problem. Specifically, we consider variants of this problem which arise in different implementations of transactional systems, namely \"requestor wins'' and \"requestor aborts'' implementations: in the former, the recipient of a coherence request is aborted, whereas in the latter, it is the requestor which has to abort. Both strategies are implemented by real systems. We show that the requestor aborts case can be reduced to a classic instance of the ski rental problem, while the requestor wins case leads to a new version of this classical problem, for which we derive optimal deterministic and randomized algorithms. Moreover, we prove that, under a simplified adversarial model, our algorithms are constant-competitive with the offline optimum in terms of throughput. We validate our algorithmic results empirically through a hardware simulation of hardware transactional memory (HTM), showing that our algorithms can lead to non-trivial performance improvements for classic concurrent data structures."}],"type":"conference","citation":{"short":"D.-A.

In each stage Player 1 hides one or two pebbles in his hand, and his opponent has to guess that number; Player 1 loses a point if Player 2 is correct, and otherwise he wins a point. As soon as Player 1 hides one pebble, the players cannot change their choices in any future stage.\r\nBlackwell and Ferguson (1968) give an ε-optimal strategy for Player 1 that hides, in each stage, one pebble with a probability that depends on the entire past history. Any strategy that depends just on the clock or on a finite memory is worthless. The long-standing natural open problem has been whether every strategy that depends just on the clock and a finite memory is worthless. We prove that there is such a strategy that is ε-optimal. In fact, we show that just two states of memory are sufficient.\r\n"}],"type":"conference","citation":{"short":"K.A. Hansen, R. Ibsen-Jensen, A.

Moser andG. Tardos,J. ACM, 57 (2010), 11] to more general discrete spaces. At each step the method picks aflaw present in the current state and goes to a new state according to some prespecified probabilitydistribution (which depends on the current state and the selected flaw). However, the recent formu-lation is less flexible than the Moser–Tardos method since it requires a specific flaw selection rule,whereas the algorithm of Moser and Tardos allows an arbitrary rule (and thus can potentially beimplemented more efficiently). We formulate a new “commutativity” condition and prove that it issufficient for an arbitrary rule to work. It also enables an efficient parallelization under an additionalassumption.
