The games are concurrent in that at each turn, both players independently propose a time delay and an action, and the action with the shorter delay is chosen. To prevent a player from winning by blocking time, we restrict each player to strategies that ensure that the player cannot be responsible for causing a zeno run. First, we present an efficient reduction of these games to turn-based (i.e., nonconcurrent) finite-state (i.e., untimed) parity games. The states of the resulting game are pairs of clock regions of the original game. Our reduction improves the best known complexity for solving timed parity games. Moreover, the rich class of algorithms for classical parity games can now be applied to timed parity games. Second, we consider two restricted classes of strategies for the player that represents the controller in a real-time synthesis problem, namely, limit-robust and bounded-robust strategies. Using a limit-robust strategy, the controller cannot choose an exact real-valued time delay but must allow for some nonzero jitter in each of its actions. If there is a given lower bound on the jitter, then the strategy is bounded-robust. We show that exact strategies are more powerful than limit-robust strategies, which are more powerful than bounded-robust strategies for any bound. For both kinds of robust strategies, we present efficient reductions to standard timed automaton games. These reductions provide algorithms for the synthesis of robust real-time controllers.","lang":"eng"}],"volume":5215,"acknowledgement":"This research was supported in part by the NSF grants CCR-0132780, CNS-0720884, and CCR-0225610, and by the European COMBEST project.","status":"public","related_material":{"record":[{"status":"public","id":"3315","relation":"later_version"}]},"extern":1,"_id":"3876","author":[{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","full_name":"Krishnendu Chatterjee","first_name":"Krishnendu","last_name":"Chatterjee"},{"orcid":"0000−0002−2985−7724","full_name":"Thomas Henzinger","first_name":"Thomas A","last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Prabhu, Vinayak S","last_name":"Prabhu","first_name":"Vinayak"}],"date_created":"2018-12-11T12:05:39Z","publication_status":"published","intvolume":"      5215","month":"10","alternative_title":["LNCS"],"title":"Timed parity games: complexity and robustness","quality_controlled":0,"page":"124 - 140","publisher":"Springer","conference":{"name":"FORMATS: Formal Modeling and Analysis of Timed Systems"}},{"volume":5201,"extern":1,"status":"public","date_updated":"2021-01-12T07:52:53Z","year":"2008","citation":{"chicago":"Chatterjee, Krishnendu, Thomas A Henzinger, and Barbara Jobstmann. “Environment Assumptions for Synthesis,” 5201:147–61.

Initial specifications are often unrealizable, which means that there is no system that implements the specification. A common reason for unrealizability is that assumptions on the environment of the system are incomplete. We study the problem of correcting an unrealizable specification phi by computing an environment assumption psi such that the new specification psi -&gt; phi is realizable. Our aim is to construct an assumption psi that constrains only the environment and is as weak as possible. We present a two-step algorithm for computing assumptions. The algorithm operates on the game graph that is used to answer the realizability question. First, we compute a safety assumption that removes a minimal set of environment edges from the graph. Second, we compute a liveness assumption that puts fairness conditions on some of the remaining environment edges. We show that the problem of finding a minimal set of fair edges is computationally hard, and we use probabilistic games to compute a locally minimal fairness assumption."}],"publist_id":"2295","page":"147 - 161","quality_controlled":0,"publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","conference":{"name":"CONCUR: Concurrency Theory"},"_id":"3877","author":[{"orcid":"0000-0002-4561-241X","full_name":"Krishnendu Chatterjee","first_name":"Krishnendu","last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000−0002−2985−7724","full_name":"Thomas Henzinger","first_name":"Thomas A","last_name":"Henzinger"},{"last_name":"Jobstmann","first_name":"Barbara","full_name":"Jobstmann, Barbara"}],"publication_status":"published","date_created":"2018-12-11T12:05:39Z","month":"07","alternative_title":["LNCS"],"title":"Environment assumptions for synthesis","intvolume":"      5201"},{"extern":1,"status":"public","acknowledgement":"This research was supported in part by the NSF grants CCR-0132780 and CNS-0720884.","volume":5356,"main_file_link":[{"url":"http://arxiv.org/abs/0804.4525","open_access":"1"}],"abstract":[{"lang":"eng","text":"We study the problem of generating a test sequence that achieves maximal coverage for a reactive system under test.

We evaluate the relative informative power of the three methodological approaches and estimate both the number of independent introduction events from a yet unknown native range somewhere in the Black Sea area, and the invasive potential of the existing introduced populations.\r\n\r\nResults\r\n\r\nThree clusters of genetically similar populations were detected, and all but one population had a similar chemical profile. Aggression between populations could be predicted from their genetic and chemical distance, and two major clusters of non-aggressive groups of populations were found. However, populations of L. neglectus did not separate into clear supercolonial associations, as is typical for other invasive ants.\r\n\r\nConclusion\r\n\r\nThe three methodological approaches gave consistent and complementary results. All joint evidence supports the inference that the 14 introduced populations of L. neglectus in Europe likely arose from only very few independent introductions from the native range, and that new infestations were typically started through introductions from other invasive populations. This indicates that existing introduced populations have a very high invasive potential when the ants are inadvertently spread by human transport.

Wingless (“ergatoid”) males never leave their maternal colony and fight remorselessly among each other for the access to emerging females. The peaceful winged males disperse after about 10 days, but beforehand also mate in the nest. In the first 5 days of their life, winged males perform a chemical female mimicry that protects them against attack and even makes them sexually attractive to ergatoid males. When older, the chemical profile of winged males no longer matches that of virgin females; nevertheless, they are still tolerated, which so far has been puzzling. Contrasting this general pattern, we have identified a single aberrant colony in which all winged males were attacked and killed by the ergatoid males. A comparative analysis of the morphology and chemical profile of these untypical attacked winged males and the tolerated males from several normal colonies revealed that normal old males are still performing some chemical mimicry to the virgin queens, though less perfect than in their young ages. The anomalous attacked winged males, on the other hand, had a very different odour to the females. Our study thus exemplifies that the analysis of rare malfunctioning can add valuable insight on functioning under normal conditions and allows the conclusion that older winged males from normal colonies of the ant C. obscurior are guarded through an imperfect chemical female mimicry, still close enough to protect against attacks by the wingless fighters yet dissimilar enough not to elicit their sexual interest."}],"volume":95,"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","publication":"Naturwissenschaften","_id":"3905","issue":"11","author":[{"first_name":"Sylvia","last_name":"Cremer","orcid":"0000-0002-2193-3868","full_name":"Cremer, Sylvia","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Patrizia","last_name":"D'Ettorre","full_name":"D'Ettorre, Patrizia"},{"first_name":"Falko","last_name":"Drijfhout","full_name":"Drijfhout, Falko"},{"first_name":"Matthew","last_name":"Sledge","full_name":"Sledge, Matthew"},{"first_name":"Stefano","last_name":"Turillazzi","full_name":"Turillazzi, Stefano"},{"full_name":"Heinze, Jürgen","first_name":"Jürgen","last_name":"Heinze"}],"date_created":"2018-12-11T12:05:48Z","oa_version":"None","publication_status":"published","intvolume":"        95","month":"08","title":"Imperfect chemical female mimicry in males of the ant Cardiocondyla obscurior","page":"1101 - 1105","language":[{"iso":"eng"}],"publisher":"Springer"},{"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","volume":3,"acknowledgement":"Funding was obtained from the European Community: FP5 EU research-training network ‘INSECTS’ (JJB SC PD FPD DPH) and FP6 Individual Marie Curie EIF grant (SC), the Alexander-von-Humboldt Foundation (Feodor-Lynen postdoctoral stipend to SC), the Danish Natural Science Research Council (JSP), the Danish National Research Foundation (JJB DRN JSP), and the Austrian Science Fund (BCS FMS CS HK).","publist_id":"2247","day":"03","doi":"10.1371/journal.pone.0003838","type":"journal_article","date_published":"2008-12-03T00:00:00Z","year":"2008","citation":{"short":"S.

Older, heavily sclerotized males are usually capable of eliminating all younger rivals, whose cuticle is still soft. In Cardiocondyla sp. A, this type of local mate competition (LMC) has turned the standard pattern of brood production of social insects upside down, in that mother queens in multi-queen colonies produce extremely long-lived sons very early in the life cycle of the colony. Here, we investigated the emergence pattern of sexuals in two species with LMC, in which males are much less long-lived. Queens of Cardiocondyla obscurior and Cardiocondyla minutior reared their first sons significantly earlier in multi-queen than in single-queen societies. In addition, first female sexuals also emerged earlier in multi-queen colonies, so that early males had mating opportunities. Hence, the timing of sexual production appears to be well predicted by evolutionary theory, in particular by local mate and queen–queen competition.

The success rate of such interactions is extremely low, because the precursor frequency of a naive T cell recognizing a specific antigen is in the range of 1:10(5)-10(6). To make this principle practicable, encounter frequencies between DCs and T cells are maximized within lymph nodes (LNs) that are compact immunological projections of the peripheral tissue they drain. But LNs are more than passive meeting places for DCs that immigrated from the tissue and lymphocytes that recirculated via the blood. The microanatomy of the LN stroma actively organizes the cellular encounters by providing preformed migration tracks that create dynamic but highly ordered movement patterns. LN architecture further acts as a sophisticated filtration system that sieves the incoming interstitial fluid at different levels and guarantees that immunologically relevant antigens are loaded on DCs or B cells while inert substances are channeled back into the blood circulation. This review focuses on the non-hematopoietic infrastructure of the lymph node. We describe the association between fibroblastic reticular cell, conduit, DC, and T cell as the essential functional unit of the T-cell cortex.","lang":"eng"}],"publist_id":"2187","doi":"10.1111/j.1600-065X.2008.00592.x","day":"07","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","volume":221},{"page":"4 - 13","quality_controlled":0,"publisher":"Academic Press","_id":"3940","publication":"Seminars in Immunology","author":[{"full_name":"Lokmic, Zerina","first_name":"Zerina","last_name":"Lokmic"},{"first_name":"Tim","last_name":"Lämmermann","full_name":"Lämmermann, Tim"},{"id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","first_name":"Michael K","last_name":"Sixt","orcid":"0000-0002-6620-9179","full_name":"Michael Sixt"},{"full_name":"Cardell, Susanna","last_name":"Cardell","first_name":"Susanna"},{"first_name":"Rupert","last_name":"Hallmann","full_name":"Hallmann, Rupert"},{"first_name":"Lydia","last_name":"Sorokin","full_name":"Sorokin, Lydia"}],"issue":"1","publication_status":"published","date_created":"2018-12-11T12:06:00Z","title":"The extracellular matrix of the spleen as a potential organizer of immune cell compartments","month":"02","intvolume":"        20","volume":20,"extern":1,"status":"public","date_updated":"2021-01-12T07:53:20Z","year":"2008","citation":{"short":"Z.

In agreement with this principle, rapidly migrating leukocytes use integrin-mediated adhesion when moving over two-dimensional surfaces. As migration on two-dimensional substrates naturally overemphasizes the role of adhesion, the contribution of integrins during three-dimensional movement of leukocytes within tissues has remained controversial. We studied the interplay between adhesive, contractile and protrusive forces during interstitial leukocyte chemotaxis in vivo and in vitro. We ablated all integrin heterodimers from murine leukocytes, and show here that functional integrins do not contribute to migration in three-dimensional environments. Instead, these cells migrate by the sole force of actin-network expansion, which promotes protrusive flowing of the leading edge. Myosin II-dependent contraction is only required on passage through narrow gaps, where a squeezing contraction of the trailing edge propels the rigid nucleus."}],"day":"01","doi":"10.1038/nature06887","status":"public","extern":1,"volume":453,"issue":"7191","author":[{"full_name":"Lämmermann, Tim","first_name":"Tim","last_name":"Lämmermann"},{"last_name":"Bader","first_name":"Bernhard","full_name":"Bader, Bernhard L"},{"full_name":"Monkley, Susan J","last_name":"Monkley","first_name":"Susan"},{"first_name":"Tim","last_name":"Worbs","full_name":"Worbs, Tim"},{"full_name":"Wedlich-Söldner, Roland","first_name":"Roland","last_name":"Wedlich Söldner"},{"full_name":"Hirsch, Karin","last_name":"Hirsch","first_name":"Karin"},{"full_name":"Keller, Markus","last_name":"Keller","first_name":"Markus"},{"full_name":"Förster, Reinhold","first_name":"Reinhold","last_name":"Förster"},{"full_name":"Critchley, David R","last_name":"Critchley","first_name":"David"},{"last_name":"Fässler","first_name":"Reinhard","full_name":"Fässler, Reinhard"},{"id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt","first_name":"Michael K","full_name":"Michael Sixt","orcid":"0000-0002-6620-9179"}],"_id":"3941","publication":"Nature","intvolume":"       453","title":"Rapid leukocyte migration by integrin-independent flowing and squeezing","month":"05","date_created":"2018-12-11T12:06:00Z","publication_status":"published","quality_controlled":0,"page":"51 - 55","publisher":"Nature Publishing Group"},{"doi":"10.1084/jem.20070846","day":"02","abstract":[{"text":"Recent in vitro studies have suggested a role for sialylation in chemokine receptor binding to its ligand (Bannert, N., S.

This prompted us to investigate chemokine-induced leukocyte adhesion in inflamed cremaster muscle venules of alpha2,3 sialyltransferase (ST3Gal-IV)-deficient mice. We found a marked reduction in leukocyte adhesion to inflamed microvessels upon injection of the CXCR2 ligands CXCL1 (keratinocyte-derived chemokine) or CXCL8 (interleukin 8). In addition, extravasation of ST3Gal-IV(-/-) neutrophils into thioglycollate-pretreated peritoneal cavities was significantly decreased. In vitro assays revealed that CXCL8 binding to isolated ST3Gal-IV(-/-) neutrophils was markedly impaired. Furthermore, CXCL1-mediated adhesion of ST3Gal-IV(-/-) leukocytes at physiological flow conditions, as well as transendothelial migration of ST3Gal-IV(-/-) leukocytes in response to CXCL1, was significantly reduced. In human neutrophils, enzymatic desialylation decreased binding of CXCR2 ligands to the neutrophil surface and diminished neutrophil degranulation in response to these chemokines. In addition, binding of alpha2,3-linked sialic acid-specific Maackia amurensis lectin II to purified CXCR2 from neuraminidase-treated CXCR2-transfected HEK293 cells was markedly impaired. Collectively, we provide substantial evidence that sialylation by ST3Gal-IV significantly contributes to CXCR2-mediated leukocyte adhesion during inflammation in vivo.","lang":"eng"}],"publist_id":"2185","date_updated":"2021-01-12T07:53:21Z","year":"2008","citation":{"ista":"Frommhold D, Ludwig A, Bixel MG, Zarbock A, Babushkina I, Weissinger M, Cauwenberghs S, Ellies L, Marth J, Beck Sickinger A, Sixt MK, Lange Sperandio B, Zernecke A, Brandt E, Weber C, Vestweber D, Ley K, Sperandio M. 2008.

Proteinase 3 (PR3) and neutrophil elastase (NE) are 2 abundant neutrophil serine proteases implicated in antimicrobial defense with overlapping and potentially redundant substrate specificity. Here, we unraveled a cooperative role for PR3 and NE in neutrophil activation and noninfectious inflammation in vivo, which we believe to be novel. Mice lacking both PR3 and NE demonstrated strongly diminished immune complex-mediated (IC-mediated) neutrophil infiltration in vivo as well as reduced activation of isolated neutrophils by ICs in vitro. In contrast, in mice lacking just NE, neutrophil recruitment to ICs was only marginally impaired. The defects in mice lacking both PR3 and NE were directly linked to the accumulation of antiinflammatory progranulin (PGRN). Both PR3 and NE cleaved PGRN in vitro and during neutrophil activation and inflammation in vivo. Local administration of recombinant PGRN potently inhibited neutrophilic inflammation in vivo, demonstrating that PGRN represents a crucial inflammation-suppressing mediator. We conclude that PR3 and NE enhance neutrophil-dependent inflammation by eliminating the local antiinflammatory activity of PGRN. Our results support the use of serine protease inhibitors as antiinflammatory agents.","lang":"eng"}],"day":"01","doi":"10.1172/JCI34694","type":"journal_article","date_published":"2008-07-01T00:00:00Z","year":"2008","citation":{"apa":"Kessenbrock, K., Fröhlich, L., Sixt, M.

They do so in the steady-state and under inflammatory conditions. Peripheral T cell tolerance or T cell priming, respectively, are the consequences of migration. The nature of dendritic cell-containing vessels was mostly defined by electron microscopy or by their lack of blood endothelial markers. Selective markers for murine lymph endothelium were hitherto rare or not available. Here, we utilised recently developed antibodies against the murine hyaluronan receptor, LYVE-1, to study the lymph vessel network in mouse skin in more detail. In hairless skin from the ears, lymph vessels were spread out in a horizontal plane. They formed anastomoses, and they possessed frequent blind endings that were occasionally open. Lymph vessels were wider than blood vessels, which were identified by their strong CD31 expression. In body wall skin LYVE-1 reactive vessels did not extend laterally but they dived straight down into the deeper dermis. There, they are connected to each other and formed a network similar to ear skin. The number and width of lymph vessels did not grossly change upon inflammatory stimuli such as skin explant culture or tape stripping. There were also no marked changes in caliber in response to the TLR 7/8 ligand Imiquimod. Double-labelling experiments of cultured skin showed that most of the strongly cell surface MHC II-expressing (i.e. activated) dendritic cells were confined to the lymph vessels. Langerin/CD207(+) cells within this population appeared later than dermal dendritic cells, i.e. langerin-negative cells. Comparable results were obtained after stimulating the skin in vivo with the TLR 7/8 ligand Imiquimod or by tape stripping. In untreated skin (i.e. steady state) a few MHC II(+) and Langerin/CD207(+) cells, presumably migrating skin dendritic cells including epidermal Langerhans cells, were consistently observed within the lymph vessels. The novel antibody reagents may serve as important tools to further study the dendritic cell traffic in the skin under physiological conditions as well as in conditions of adoptive dendritic cell transfer in immunotherapy.","lang":"eng"}],"day":"30","doi":"10.1016/j.imbio.2008.07.025"},{"quality_controlled":0,"page":"257 - 282","publisher":"American Mathematical Society","author":[{"id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","first_name":"Herbert","last_name":"Edelsbrunner","orcid":"0000-0002-9823-6833","full_name":"Herbert Edelsbrunner"},{"full_name":"Harer, John","last_name":"Harer","first_name":"John"}],"publication":"Surveys on Discrete and Computational Geometry: Twenty Years Later","_id":"3969","title":"Persistent homology - a survey","month":"03","alternative_title":["Contemporary Mathematics"],"date_created":"2018-12-11T12:06:11Z","publication_status":"published","status":"public","extern":1,"acknowledgement":"Supported in part by DARPA under grants HR0011-05-1-0007 and HR0011-05-0057 and by the NSF under grant DBI-06-06873.","type":"book_chapter","date_published":"2008-03-28T00:00:00Z","citation":{"ista":"Edelsbrunner H, Harer J. 2008.Persistent homology - a survey.

Identifying subtle patterns of interest in large amounts of data (tens of thousands of profiles) associated with a certain level of noise remains a challenge. A microarray time series was recently generated to study the transcriptional program of the mouse segmentation clock, a biological oscillator associated with the periodic formation of the segments of the body axis. A method related to Fourier analysis, the Lomb-Scargle periodogram, was used to detect periodic profiles in the dataset, leading to the identification of a novel set of cyclic genes associated with the segmentation clock. Here, we applied to the same microarray time series dataset four distinct mathematical methods to identify significant patterns in gene expression profiles. These methods are called: Phase consistency, Address reduction, Cyclohedron test and Stable persistence, and are based on different conceptual frameworks that are either hypothesis- or data-driven. Some of the methods, unlike Fourier transforms, are not dependent on the assumption of periodicity of the pattern of interest. Remarkably, these methods identified blindly the expression profiles of known cyclic genes as the most significant patterns in the dataset. Many candidate genes predicted by more than one approach appeared to be true positive cyclic genes and will be of particular interest for future research. In addition, these methods predicted novel candidate cyclic genes that were consistent with previous biological knowledge and experimental validation in mouse embryos. Our results demonstrate the utility of these novel pattern detection strategies, notably for detection of periodic profiles, and suggest that combining several distinct mathematical approaches to analyze microarray datasets is a valuable strategy for identifying genes that exhibit novel, interesting transcriptional patterns.","lang":"eng"}],"publist_id":"2157","doi":"10.1371/journal.pone.0002856","day":"06","date_published":"2008-08-06T00:00:00Z","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"date_updated":"2021-01-12T07:53:33Z","year":"2008","citation":{"short":"M.
