This work considers some of the theoretical power and limitations of this technique. We focus on concurrent systems in which processes communicate via pairwise rendezvous, as well as the special cases of disjunctive guards and token passing; specifications are expressed in indexed temporal logic without the next operator; and the underlying network topologies are generated by suitable Monadic Second Order Logic formulas and graph operations. First, we settle the exact computational complexity of the parameterized model checking problem for some of our concurrent systems, and establish new decidability results for others. Second, we consider the cases that model checking the parameterized system can be reduced to model checking some fixed number of processes, the number is known as a cutoff. We provide many cases for when such cutoffs can be computed, establish lower bounds on the size of such cutoffs, and identify cases where no cutoff exists. Third, we consider cases for which the parameterized system is equivalent to a single finite-state system (more precisely a Büchi word automaton), and establish tight bounds on the sizes of such automata.","lang":"eng"}],"date_updated":"2021-01-12T06:54:59Z","year":"2014","day":"01","alternative_title":["LNCS"],"month":"09","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","status":"public","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","title":"Parameterized model checking of rendezvous systems"},{"ec_funded":1,"month":"09","oa":1,"status":"public","_id":"2053","year":"2014","date_updated":"2021-01-12T06:55:00Z","abstract":[{"lang":"eng","text":"In contrast to the usual understanding of probabilistic systems as stochastic processes, recently these systems have also been regarded as transformers of probabilities.

Our definition applies in the same way to discrete systems as well as to systems with uncountable state and action spaces. Several examples demonstrate that our definition refines the understanding of behavioural equivalences of probabilistic systems. In particular, it solves a longstanding open problem concerning the representation of memoryless continuous time by memoryfull continuous time.

The objectives are ω-regular winning conditions specified as parity objectives. We consider the qualitative analysis problems: the computation of the almost-sure and limit-sure winning set of states, where player 1 can ensure to win with probability 1 and with probability arbitrarily close to 1, respectively. In general the almost-sure and limit-sure winning strategies require both infinite-memory as well as infinite-precision (to describe probabilities). While the qualitative analysis problem for concurrent parity games with infinite-memory, infinite-precision randomized strategies was studied before, we study the bounded-rationality problem for qualitative analysis of concurrent parity games, where the strategy set for player 1 is restricted to bounded-resource strategies. In terms of precision, strategies can be deterministic, uniform, finite-precision, or infinite-precision; and in terms of memory, strategies can be memoryless, finite-memory, or infinite-memory. We present a precise and complete characterization of the qualitative winning sets for all combinations of classes of strategies. In particular, we show that uniform memoryless strategies are as powerful as finite-precision infinite-memory strategies, and infinite-precision memoryless strategies are as powerful as infinite-precision finite-memory strategies. We show that the winning sets can be computed in (n2d+3) time, where n is the size of the game structure and 2d is the number of priorities (or colors), and our algorithms are symbolic. The membership problem of whether a state belongs to a winning set can be decided in NP ∩ coNP. Our symbolic algorithms are based on a characterization of the winning sets as μ-calculus formulas, however, our μ-calculus formulas are crucially different from the ones for concurrent parity games (without bounded rationality); and our memoryless witness strategy constructions are significantly different from the infinite-memory witness strategy constructions for concurrent parity games."}],"date_updated":"2023-02-23T11:23:36Z","year":"2014","month":"09","ec_funded":1,"status":"public","oa_version":"None","date_published":"2014-09-01T00:00:00Z","doi":"10.1007/978-3-662-44584-6_37","publication_status":"published","conference":{"location":"Rome, Italy","end_date":"2014-09-05","name":"CONCUR: Concurrency Theory","start_date":"2014-09-02"},"intvolume":"      8704","citation":{"chicago":"Chatterjee, Krishnendu. “Qualitative Concurrent Parity Games: Bounded Rationality.” In <i>Lecture Notes in Computer Science (Including Subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)</i>, edited by Paolo Baldan and Daniele Gorla, 8704:544–59.

A sufficient condition for defining a CTMC over the aggregates is presented as a variant of weak lumpability, which also characterizes that the measure over the original process can be recovered from that of the aggregated one. We show how the applicability of de-aggregation depends on the initial distribution. The application section is devoted to illustrate how the developed theory aids in reducing CTMC models of biochemical systems particularly in connection to protein-protein interactions. We assume that the model is written by a biologist in form of site-graph-rewrite rules. Site-graph-rewrite rules compactly express that, often, only a local context of a protein (instead of a full molecular species) needs to be in a certain configuration in order to trigger a reaction event. This observation leads to suitable aggregate Markov chains with smaller state spaces, thereby providing sufficient reduction in computational complexity. This is further exemplified in two case studies: simple unbounded polymerization and early EGFR/insulin crosstalk.","lang":"eng"}],"issue":"3","date_updated":"2021-01-12T06:55:01Z","year":"2014","_id":"2056","status":"public","oa":1,"month":"11","doi":"10.1007/s00285-013-0738-7","publication_status":"published","oa_version":"Submitted Version","date_published":"2014-11-20T00:00:00Z","scopus_import":1,"main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1303.4532"}],"intvolume":"        69","citation":{"chicago":"Ganguly, Arnab, Tatjana Petrov, and Heinz Koeppl. “Markov Chain Aggregation and Its Applications to Combinatorial Reaction Networks.” <i>Journal of Mathematical Biology</i>.

Two kinds of fusion schemes are generally considered: The early fusion and the late fusion. We focus on late classifier fusion, where one combines the scores of each modality at the decision level. To tackle this problem, we investigate a recent and elegant well-founded quadratic program named MinCq coming from the machine learning PAC-Bayesian theory. MinCq looks for the weighted combination, over a set of real-valued functions seen as voters, leading to the lowest misclassification rate, while maximizing the voters’ diversity. We propose an extension of MinCq tailored to multimedia indexing. Our method is based on an order-preserving pairwise loss adapted to ranking that allows us to improve Mean Averaged Precision measure while taking into account the diversity of the voters that we want to fuse.

However, the cells establishing these gradients during microspore embryogenesis remain to be identified. For the first time, we describe, using the DR5 or DR5rev reporter gene systems, the GFP- and GUS-based auxin biosensors to monitor auxin during Brassica napus androgenesis at cellular resolution in the initial stages. Our study provides evidence that the distribution of auxin changes during embryo development and depends on the temperature-inducible in vitro culture conditions. For this, microspores (mcs) were induced to embryogenesis by heat treatment and then subjected to genetic modification via Agrobacterium tumefaciens. The duration of high temperature treatment had a significant influence on auxin distribution in isolated and in vitro-cultured microspores and on microspore-derived embryo development. In the “mild” heat-treated (1 day at 32 °C) mcs, auxin localized in a polar way already at the uni-nucleate microspore, which was critical for the initiation of embryos with suspensor-like structure. Assuming a mean mcs radius of 20 μm, endogenous auxin content in a single cell corresponded to concentration of 1.01 μM. In mcs subjected to a prolonged heat (5 days at 32 °C), although auxin concentration increased dozen times, auxin polarization was set up at a few-celled pro-embryos without suspensor. Those embryos were enclosed in the outer wall called the exine. The exine rupture was accompanied by the auxin gradient polarization. Relative quantitative estimation of auxin, using time-lapse imaging, revealed that primordia possess up to 1.3-fold higher amounts than those found in the root apices of transgenic MDEs in the presence of exogenous auxin. Our results show, for the first time, which concentration of endogenous auxin coincides with the first cell division and how the high temperature interplays with auxin, by what affects delay early establishing microspore polarity. Moreover, we present how the local auxin accumulation demonstrates the apical–basal axis formation of the androgenic embryo and directs the axiality of the adult haploid plant.","lang":"eng"}],"_id":"2059","oa":1,"status":"public","month":"02"},{"scopus_import":1,"publist_id":"4985","intvolume":"       251","citation":{"chicago":"Mazur, Ewa, Ewa Kurczyñska, and Jiří Friml. “Cellular Events during Interfascicular Cambium Ontogenesis in Inflorescence Stems of Arabidopsis.” <i>Protoplasma</i>.

Arabidopsis thaliana emerges as a good model plant for such a kind of study. Thus, this paper reports on cellular events taking place in the interfascicular regions of inflorescence stems of A. thaliana, leading to the development of interfascicular cambium from differentiated interfascicular parenchyma cells (IPC). These events are as follows: appearance of auxin accumulation, PIN1 gene expression, polar PIN1 protein localization in the basal plasma membrane and periclinal divisions. Distribution of auxin was observed to be higher in differentiating into cambium parenchyma cells compared to cells within the pith and cortex. Expression of PIN1 in IPC was always preceded by auxin accumulation. Basal localization of PIN1 was already established in the cells prior to their periclinal division. These cellular events initiated within parenchyma cells adjacent to the vascular bundles and successively extended from that point towards the middle region of the interfascicular area, located between neighboring vascular bundles. The final consequence of which was the closure of the cambial ring within the stem. Changes in the chemical composition of IPC walls were also detected and included changes of pectic epitopes, xyloglucans (XG) and extensins rich in hydroxyproline (HRGPs). In summary, results presented in this paper describe interfascicular cambium ontogenesis in terms of successive cellular events in the interfascicular regions of inflorescence stems of Arabidopsis."}],"issue":"5","date_updated":"2021-01-12T06:55:03Z","_id":"2061","author":[{"full_name":"Mazur, Ewa","first_name":"Ewa","last_name":"Mazur"},{"first_name":"Ewa","last_name":"Kurczyñska","full_name":"Kurczyñska, Ewa"},{"full_name":"Friml, Jiří","first_name":"Jiří","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml"}]},{"quality_controlled":"1","volume":345,"publist_id":"4984","pubrep_id":"821","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"PeJo"}],"has_accepted_license":"1","date_created":"2018-12-11T11:55:29Z","publication":"Science","publisher":"American Association for the Advancement of Science","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","title":"Fast-spiking parvalbumin^+ GABAergic interneurons: From cellular design to microcircuit function","project":[{"_id":"25C26B1E-B435-11E9-9278-68D0E5697425","grant_number":"P24909-B24","call_identifier":"FWF","name":"Mechanisms of transmitter release at GABAergic synapses"},{"call_identifier":"FP7","name":"Nanophysiology of fast-spiking, parvalbumin-expressing GABAergic interneurons","_id":"25C0F108-B435-11E9-9278-68D0E5697425","grant_number":"268548"}],"author":[{"full_name":"Hu, Hua","id":"4AC0145C-F248-11E8-B48F-1D18A9856A87","last_name":"Hu","first_name":"Hua"},{"first_name":"Jian","id":"3614E438-F248-11E8-B48F-1D18A9856A87","last_name":"Gan","full_name":"Gan, Jian"},{"orcid":"0000-0001-5001-4804","first_name":"Peter M","last_name":"Jonas","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","full_name":"Jonas, Peter M"}],"file":[{"content_type":"application/pdf","relation":"main_file","file_size":215514,"file_id":"5185","creator":"system","checksum":"a0036a589037d37e86364fa25cc0a82f","access_level":"open_access","file_name":"IST-2017-821-v1+1_1255263JonasPVReviewTextR_Final.pdf","date_updated":"2020-07-14T12:45:27Z","date_created":"2018-12-12T10:16:00Z"},{"file_size":1732723,"content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_id":"5186","checksum":"e1f57d2713725449cb898fdcb8ef47b8","creator":"system","date_created":"2018-12-12T10:16:01Z","date_updated":"2020-07-14T12:45:27Z","file_name":"IST-2017-821-v1+2_1255263JonasPVReviewFigures_Final.pdf"}],"day":"01","citation":{"short":"H.

In 1995, the properties of these interneurons were completely unknown. Twenty years later, thanks to the massive use of subcellular patch-clamp techniques, simultaneous multiple-cell recording, optogenetics, in vivo measurements, and computational approaches, our knowledge about PV+ interneurons became more extensive than for several types of pyramidal neurons. These findings have implications beyond the “small world” of basic research on GABAergic cells. For example, the results provide a first proof of principle that neuroscientists might be able to close the gaps between the molecular, cellular, network, and behavioral levels, representing one of the main challenges at the present time. Furthermore, the results may form the basis for PV+ interneurons as therapeutic targets for brain disease in the future. However, much needs to be learned about the basic function of these interneurons before clinical neuroscientists will be able to use PV+ interneurons for therapeutic purposes.","lang":"eng"}],"year":"2014"},{"publist_id":"4978","volume":8559,"quality_controlled":"1","intvolume":"      8559","citation":{"chicago":"Chatterjee, Krishnendu, Martin Chmelik, and Przemyslaw Daca. “CEGAR for Qualitative Analysis of Probabilistic Systems,” 8559:473–90.

Four excitatory synapses formed by two distinct inputs, auditory nerve (AN) and parallel fibers (PF), on different cell types were analyzed. These excitatory synapse types included AN synapses on bushy cells (AN-BC synapses) and fusiform cells (AN-FC synapses) and PF synapses on FC (PF-FC synapses) and cartwheel cell spines (PF-CwC synapses). Immunogold labeling revealed differences in synaptic structure as well as AMPAR and NMDAR number and/or density in both AN and PF synapses, indicating a target-dependent organization. The immunogold receptor labeling also identified differences in the synaptic organization of FCs based on AN or PF connections, indicating an input-dependent organization in FCs. Among the four excitatory synapse types, the AN-BC synapses were the smallest and had the most densely packed intramembrane particles (IMPs), whereas the PF-CwC synapses were the largest and had sparsely packed IMPs. All four synapse types showed positive correlations between the IMP-cluster area and the AMPAR number, indicating a common intrasynapse-type relationship for glutamatergic synapses. Immunogold particles for AMPARs were distributed over the entire area of individual AN synapses; PF synapses often showed synaptic areas devoid of labeling. The gold-labeling for NMDARs occurred in a mosaic fashion, with less positive correlations between the IMP-cluster area and the NMDAR number. Our observations reveal target- and input-dependent features in the structure, number, and organization of AMPARs and NMDARs in AN and PF synapses.","lang":"eng"}],"issue":"18","year":"2014","_id":"2064","status":"public","oa":1,"month":"07","page":"4023 - 4042","date_created":"2018-12-11T11:55:30Z","publication":"Journal of Comparative Neurology","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"RySh"}],"publist_id":"4974","quality_controlled":"1","volume":522,"acknowledgement":"National Institutes of Health (NIH) Grant Number: 1R01DC013048‐0; Biotechnology and Biological Sciences Research Council, UK Grant Number: BB/J015938/1\r\n","day":"29","author":[{"full_name":"Rubio, Maía","first_name":"Maía","last_name":"Rubio"},{"full_name":"Fukazawa, Yugo","last_name":"Fukazawa","first_name":"Yugo"},{"full_name":"Kamasawa, Naomi","last_name":"Kamasawa","first_name":"Naomi"},{"full_name":"Clarkson, Cheryl","first_name":"Cheryl","last_name":"Clarkson"},{"last_name":"Molnár","first_name":"Elek","full_name":"Molnár, Elek"},{"first_name":"Ryuichi","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","last_name":"Shigemoto","full_name":"Shigemoto, Ryuichi"}],"publisher":"Wiley-Blackwell","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","title":"Target- and input-dependent organization of AMPA and NMDA receptors in synaptic connections of the cochlear nucleus"},{"pubrep_id":"682","publist_id":"4955","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"838"}]},"quality_controlled":"1","editor":[{"first_name":"Juan","last_name":"Garay","full_name":"Garay, Juan"},{"last_name":"Gennaro","first_name":"Rosario","full_name":"Gennaro, Rosario"}],"volume":8616,"page":"113 - 130","date_created":"2018-12-11T11:55:36Z","has_accepted_license":"1","department":[{"_id":"KrPi"}],"language":[{"iso":"eng"}],"type":"conference","title":"The exact PRF-security of NMAC and HMAC","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","publisher":"Springer","alternative_title":["LNCS"],"day":"01","file":[{"file_size":492310,"content_type":"application/pdf","relation":"main_file","access_level":"open_access","checksum":"dab6ab36a5f6af94f2b597e6404ed11d","file_id":"4999","creator":"system","date_created":"2018-12-12T10:13:17Z","file_name":"IST-2016-682-v1+1_578.pdf","date_updated":"2020-07-14T12:45:28Z"}],"author":[{"last_name":"Gazi","id":"3E0BFE38-F248-11E8-B48F-1D18A9856A87","first_name":"Peter","full_name":"Gazi, Peter"},{"first_name":"Krzysztof Z","orcid":"0000-0002-9139-1654","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","last_name":"Pietrzak","full_name":"Pietrzak, Krzysztof Z"},{"last_name":"Rybar","id":"2B3E3DE8-F248-11E8-B48F-1D18A9856A87","first_name":"Michal","full_name":"Rybar, Michal"}],"project":[{"grant_number":"259668","_id":"258C570E-B435-11E9-9278-68D0E5697425","name":"Provable Security for Physical Cryptography","call_identifier":"FP7"}],"ddc":["000","004"],"file_date_updated":"2020-07-14T12:45:28Z","citation":{"chicago":"Gazi, Peter, Krzysztof Z Pietrzak, and Michal Rybar. “The Exact PRF-Security of NMAC and HMAC.” edited by Juan Garay and Rosario Gennaro, 8616:113–30.

A practical single-key variant of NMAC called HMAC is a very popular and widely deployed message authentication code (MAC). Security proofs and attacks for NMAC can typically be lifted to HMAC. NMAC was introduced by Bellare, Canetti and Krawczyk [Crypto'96], who proved it to be a secure pseudorandom function (PRF), and thus also a MAC, assuming that (1) f is a PRF and (2) the function we get when cascading f is weakly collision-resistant. Unfortunately, HMAC is typically instantiated with cryptographic hash functions like MD5 or SHA-1 for which (2) has been found to be wrong. To restore the provable guarantees for NMAC, Bellare [Crypto'06] showed its security based solely on the assumption that f is a PRF, albeit via a non-uniform reduction. - Our first contribution is a simpler and uniform proof for this fact: If f is an ε-secure PRF (against q queries) and a δ-non-adaptively secure PRF (against q queries), then NMAC f is an (ε+ℓqδ)-secure PRF against q queries of length at most ℓ blocks each. - We then show that this ε+ℓqδ bound is basically tight. For the most interesting case where ℓqδ ≥ ε we prove this by constructing an f for which an attack with advantage ℓqδ exists. This also violates the bound O(ℓε) on the PRF-security of NMAC recently claimed by Koblitz and Menezes. - Finally, we analyze the PRF-security of a modification of NMAC called NI [An and Bellare, Crypto'99] that differs mainly by using a compression function with an additional keying input. This avoids the constant rekeying on multi-block messages in NMAC and allows for a security proof starting by the standard switch from a PRF to a random function, followed by an information-theoretic analysis. We carry out such an analysis, obtaining a tight ℓq2/2 c bound for this step, improving over the trivial bound of ℓ2q2/2c. The proof borrows combinatorial techniques originally developed for proving the security of CBC-MAC [Bellare et al., Crypto'05]."}],"issue":"1","date_updated":"2023-09-07T12:02:27Z","_id":"2082"},{"scopus_import":1,"file_date_updated":"2020-07-14T12:45:28Z","ddc":["570"],"intvolume":"        68","citation":{"short":"M.

Using a single-cell alga Chlamydomonas reinhardtii, we investigated how sex and migration affected rates of evolutionary rescue in a sink environment, and subsequent changes in fitness following evolutionary rescue. We show that sex and migration affect both the rate of evolutionary rescue and subsequent adaptation. However, their combined effects change as the populations adapt to a sink habitat. Both sex and migration independently increased rates of evolutionary rescue, but the effect of sex on subsequent fitness improvements, following initial rescue, changed with migration, as sex was beneficial in the absence of migration but constraining adaptation when combined with migration.

We screened light-oxygen-voltage (LOV)-sensing domains for their ability to activate RTKs by light-activated dimerization. Incorporation of LOV domains found in aureochrome photoreceptors of stramenopiles resulted in robust activation of the fibroblast growth factor receptor 1 (FGFR1), epidermal growth factor receptor (EGFR) and rearranged during transfection (RET). In human cancer and endothelial cells, light induced cellular signalling with spatial and temporal precision. Furthermore, light faithfully mimicked complex mitogenic and morphogenic cell behaviour induced by growth factors.

Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness. We apply harmonic radar technology to characterize the impact of an emerging pathogen - Nosema ceranae (Microsporidia) - on honeybee (Apis mellifera) flight and orientation performance in the field. Honeybees are the most important commercial pollinators. Emerging diseases have been proposed to play a prominent role in colony decline, partly through sub-lethal behavioural manipulation of their hosts. We found that homing success was significantly reduced in diseased (65.8%) versus healthy foragers (92.5%). Although lost bees had significantly reduced continuous flight times and prolonged resting times, other flight characteristics and navigational abilities showed no significant difference between infected and non-infected bees. Our results suggest that infected bees express normal flight characteristics but are constrained in their homing ability, potentially compromising the colony by reducing its resource inputs, but also counteracting the intra-colony spread of infection. We provide the first high-resolution analysis of sub-lethal effects of an emerging disease on insect flight behaviour. The potential causes and the implications for both host and parasite are discussed.","lang":"eng"}],"year":"2014","article_number":"e103989","_id":"2086","status":"public","oa":1,"month":"08","has_accepted_license":"1","date_created":"2018-12-11T11:55:37Z","publication":"PLoS One","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"SyCr"}],"publist_id":"4949","pubrep_id":"437","volume":9,"quality_controlled":"1","related_material":{"record":[{"status":"public","relation":"research_data","id":"9888"}]},"acknowledgement":"This study was funded jointly by a grant from BBSRC, Defra, NERC, the Scottish Government and the Wellcome Trust, under the Insect Pollinators Initiative (grant numbers BB/I00097/1 and BB/I000100/1).

The long-standing best known upper bound for solving the problem is Õ(n ⋅ m), where n is the number of vertices and m is the number of edges in the graph. We are the first to break the Õ(n ⋅ m) boundary by presenting a new technique that reduces the running time to O(n2). This bound also leads to O(n2)-time algorithms for computing the set of almost-sure winning vertices for Büchi objectives (1) in alternating games with probabilistic transitions (improving an earlier bound of Õ(n ⋅ m)), (2) in concurrent graph games with constant actions (improving an earlier bound of O(n3)), and (3) in Markov decision processes (improving for m&gt;n4/3 an earlier bound of O(m ⋅ √m)). We then show how to maintain the winning set for Büchi objectives in alternating games under a sequence of edge insertions or a sequence of edge deletions in O(n) amortized time per operation. Our algorithms are the first dynamic algorithms for this problem. We then consider another core graph theoretic problem in verification of probabilistic systems, namely computing the maximal end-component decomposition of a graph. We present two improved static algorithms for the maximal end-component decomposition problem. Our first algorithm is an O(m ⋅ √m)-time algorithm, and our second algorithm is an O(n2)-time algorithm which is obtained using the same technique as for alternating Büchi games. Thus, we obtain an O(min &amp;lcu;m ⋅ √m,n2})-time algorithm improving the long-standing O(n ⋅ m) time bound. Finally, we show how to maintain the maximal end-component decomposition of a graph under a sequence of edge insertions or a sequence of edge deletions in O(n) amortized time per edge deletion, and O(m) worst-case time per edge insertion. Again, our algorithms are the first dynamic algorithms for this problem.","lang":"eng"}],"date_updated":"2025-06-02T08:53:48Z","_id":"2141","article_number":"a15","article_processing_charge":"No","publist_id":"4883","related_material":{"record":[{"status":"public","relation":"earlier_version","id":"3165"}]},"volume":61,"quality_controlled":"1","publication":"Journal of the ACM","date_created":"2018-12-11T11:55:57Z","department":[{"_id":"KrCh"}],"language":[{"iso":"eng"}],"type":"journal_article","title":"Efficient and dynamic algorithms for alternating Büchi games and maximal end-component decomposition","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","publisher":"ACM","day":"01","author":[{"orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu"},{"full_name":"Henzinger, Monika H","first_name":"Monika H","orcid":"0000-0002-5008-6530","last_name":"Henzinger","id":"540c9bbd-f2de-11ec-812d-d04a5be85630"}],"project":[{"_id":"2584A770-B435-11E9-9278-68D0E5697425","grant_number":"P 23499-N23","name":"Modern Graph Algorithmic Techniques in Formal Verification","call_identifier":"FWF"},{"name":"Efficient Algorithms for Computer Aided Verification","_id":"25892FC0-B435-11E9-9278-68D0E5697425","grant_number":"ICT15-003"},{"name":"Game Theory","call_identifier":"FWF","_id":"25863FF4-B435-11E9-9278-68D0E5697425","grant_number":"S11407"},{"grant_number":"279307","_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications","call_identifier":"FP7"},{"name":"Microsoft Research Faculty Fellowship","_id":"2587B514-B435-11E9-9278-68D0E5697425"}]},{"author":[{"full_name":"Bauer, Ulrich","orcid":"0000-0002-9683-0724","first_name":"Ulrich","last_name":"Bauer","id":"2ADD483A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Lesnick, Michael","first_name":"Michael","last_name":"Lesnick"}],"project":[{"call_identifier":"FP7","name":"Topological Complex Systems","grant_number":"318493","_id":"255D761E-B435-11E9-9278-68D0E5697425"}],"_id":"2153","abstract":[{"text":"We define a simple, explicit map sending a morphism f : M → N of pointwise finite dimensional persistence modules to a matching between the barcodes of M and N.

The largest possible value of cd has been the subject of ongoing research. Recently Gromov improved the existing lower bounds considerably by introducing a new, topological proof method. We provide an exposition of the combinatorial component of Gromov's approach, in terms accessible to combinatorialists and discrete geometers, and we investigate the limits of his method. In particular, we give tighter bounds on the cofilling profiles for the (n - 1)-simplex. These bounds yield a minor improvement over Gromov's lower bounds on cd for large d, but they also show that the room for further improvement through the cofilling profiles alone is quite small. We also prove a slightly better lower bound for c3 by an approach using an additional structure besides the cofilling profiles. We formulate a combinatorial extremal problem whose solution might perhaps lead to a tight lower bound for cd.","lang":"eng"}],"date_updated":"2021-01-12T06:55:38Z","_id":"2154","oa":1,"status":"public","month":"07"},{"quality_controlled":"1","publist_id":"4851","language":[{"iso":"eng"}],"department":[{"_id":"HeEd"}],"type":"conference","date_created":"2018-12-11T11:56:01Z","page":"484 - 490","publication":"Proceedings of the Annual Symposium on Computational Geometry","title":"The morse theory of Čech and Delaunay filtrations","publisher":"ACM","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","project":[{"name":"Topological Complex Systems","call_identifier":"FP7","_id":"255D761E-B435-11E9-9278-68D0E5697425","grant_number":"318493"}],"author":[{"last_name":"Bauer","id":"2ADD483A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9683-0724","first_name":"Ulrich","full_name":"Bauer, Ulrich"},{"first_name":"Herbert","orcid":"0000-0002-9823-6833","last_name":"Edelsbrunner","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","full_name":"Edelsbrunner, Herbert"}],"day":"01","acknowledgement":"This research is partially supported by ESF under the ACAT Research Network Programme, and by the Russian Government under mega project 11.G34.31.0053","citation":{"ista":"Bauer U, Edelsbrunner H. 2014.

Under this distance, the Reeb graph is stable against small changes of input functions. At the same time, it remains discriminative at differentiating input functions. In particular, the main result is that the functional distortion distance between two Reeb graphs is bounded from below by the bottleneck distance between both the ordinary and extended persistence diagrams for appropriate dimensions. As an application of our results, we analyze a natural simplification scheme for Reeb graphs, and show that persistent features in Reeb graph remains persistent under simplification. Understanding the stability of important features of the Reeb graph under simplification is an interesting problem on its own right, and critical to the practical usage of Reeb graphs.
