At every round of a game, each player simultaneously and independently selects a move; the moves jointly determine the transition to a successor state. Two basic objectives are the safety objective to stay forever in a given set of states, and its dual, the reachability objective to reach a given set of states. We present in this paper a strategy improvement algorithm for computing the value of a concurrent safety game, that is, the maximal probability with which player 1 can enforce the safety objective. The algorithm yields a sequence of player-1 strategies which ensure probabilities of winning that converge monotonically to the value of the safety game. Our result is significant because the strategy improvement algorithm provides, for the first time, a way to approximate the value of a concurrent safety game from below. Since a value iteration algorithm, or a strategy improvement algorithm for reachability games, can be used to approximate the same value from above, the combination of both algorithms yields a method for computing a converging sequence of upper and lower bounds for the values of concurrent reachability and safety games. Previous methods could approximate the values of these games only from one direction, and as no rates of convergence are known, they did not provide a practical way to solve these games.","lang":"eng"}],"extern":1,"file":[{"creator":"system","date_updated":"2020-07-14T12:46:31Z","date_created":"2018-12-12T10:08:03Z","content_type":"application/pdf","file_size":212369,"checksum":"ce7dc1667502e26b23c07a767ac41ae6","file_id":"4662","file_name":"IST-2012-37-v1+1_Termination_criteria_for_solving_concurrent_safety_and_reachability_games.pdf","access_level":"open_access","relation":"main_file"}],"date_published":"2009-01-01T00:00:00Z","month":"01","year":"2009","doi":"10.1137/1.9781611973068.23","date_updated":"2021-01-12T07:59:35Z","date_created":"2018-12-11T12:09:24Z","oa":1,"conference":{"name":"SODA: Symposium on Discrete Algorithms"},"publist_id":"176","file_date_updated":"2020-07-14T12:46:31Z","type":"conference","title":"Termination criteria for solving concurrent safety and reachability games","_id":"4544","publication_status":"published","status":"public"},{"abstract":[{"lang":"eng","text":"A stochastic game is a two-player game played oil a graph, where in each state the successor is chosen either by One of the players, or according to a probability distribution.

However, among two implementations that satisfy a given specification, one may be preferred to another. For example, if a specification asks that every request is followed by a response, one may prefer an implementation that generates responses quickly but does not generate unnecessary responses. We use quantitative properties to measure the “goodness” of an implementation. Using games with corresponding quantitative objectives, we can synthesize “optimal” implementations, which are preferred among the set of possible implementations that satisfy a given specification.\r\nIn particular, we show how automata with lexicographic mean-payoff conditions can be used to express many interesting quantitative properties for reactive systems. In this framework, the synthesis of optimal implementations requires the solution of lexicographic mean-payoff games (for safety requirements), and the solution of games with both lexicographic mean-payoff and parity objectives (for liveness requirements). We present algorithms for solving both kinds of novel graph games.","lang":"eng"}],"external_id":{"arxiv":["0904.2638"]},"date_published":"2009-06-19T00:00:00Z","year":"2009","acknowledgement":"This research was supported by the Swiss National Science Foundation (Indo-Swiss Research Program and NCCR MICS) and the European Union projects COMBEST and COCONUT.","doi":"10.1007/978-3-642-02658-4_14","alternative_title":["LNCS"],"date_created":"2018-12-11T12:09:31Z","conference":{"end_date":"2009-07-02","location":"Grenoble, France","name":"CAV: Computer Aided Verification","start_date":"2009-06-26"},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"type":"conference","title":"Better quality in synthesis through quantitative objectives","project":[{"call_identifier":"FP7","name":"COMponent-Based Embedded Systems design Techniques","grant_number":"215543","_id":"25EFB36C-B435-11E9-9278-68D0E5697425"}],"publication_status":"published","ec_funded":1,"page":"140 - 156","citation":{"ista":"Bloem R, Chatterjee K, Henzinger TA, Jobstmann B. 2009.

Our main results are twofold. First, we present a complete picture of the computational complexity of the qualitative analysis of POMDPs with parity objectives (a canonical form to express omega-regular objectives) and its subclasses. Our contribution consists in establishing several upper and lower bounds that were not known in literature. Second, we present optimal bounds (matching upper and lower bounds) on the memory required by pure and randomized observation-based strategies for the qualitative analysis of POMDPs with parity objectives and its subclasses.","lang":"eng"}],"oa_version":"Published Version","author":[{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X"},{"last_name":"Doyen","full_name":"Doyen, Laurent","first_name":"Laurent"},{"last_name":"Henzinger","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A","orcid":"0000−0002−2985−7724"}],"day":"09","publication_status":"published","type":"technical_report","title":"Qualitative analysis of partially-observable Markov decision processes","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","alternative_title":["IST Austria Technical Report"],"date_created":"2018-12-12T11:39:05Z","doi":"10.15479/AT:IST-2009-0001","year":"2009","publication_identifier":{"issn":["2664-1690"]}},{"publication_status":"published","status":"public","_id":"2868","type":"journal_article","title":"Hormone interactions at the root apical meristem","publist_id":"3903","date_created":"2018-12-11T12:00:01Z","doi":"10.1007/s11103-008-9393-6","date_updated":"2021-01-12T07:00:22Z","year":"2009","month":"03","publication":"Plant Molecular Biology","extern":1,"date_published":"2009-03-01T00:00:00Z","intvolume":"        69","publisher":"Springer","abstract":[{"text":"Plants exhibit an amazing developmental flexibility. Plant embryogenesis results in the establishment of a simple apical-basal axis represented by apical shoot and basal root meristems. Later, during postembryonic growth, shaping of the plant body continues by the formation and activation of numerous adjacent meristems that give rise to lateral shoot branches, leaves, flowers, or lateral roots. This developmental plasticity reflects an important feature of the plant's life strategy based on the rapid reaction to different environmental stimuli, such as temperature fluctuations, availability of nutrients, light or water and response resulting in modulation of developmental programs. Plant hormones are important endogenous factors for the integration of these environmental inputs and regulation of plant development. After a period of studies focused primarily on single hormonal pathways that enabled us to understand the hormone perception and signal transduction mechanisms, it became obvious that the developmental output mediated by a single hormonal pathway is largely modified through a whole network of interactions with other hormonal pathways. In this review, we will summarize recent knowledge on hormonal networks that regulate the development and growth of root with focus on the hormonal interactions that shape the root apical meristem.\n","lang":"eng"}],"quality_controlled":0,"volume":69,"citation":{"ieee":"E.

We achieve this by maintaining an auxiliary graph whose nodes correspond to alternating trees in the Edmonds’s algorithm. While our use of priority queues does not improve the worst-case complexity, it appears to lead to an efficient technique. In the majority of our tests Blossom V outperformed previous implementations of Cook and Rohe (INFORMS J Comput 11(2):138–148, 1999) and Mehlhorn and Schäfer (J Algorithmics Exp (JEA) 7:4, 2002), sometimes by an order of magnitude.

They induce highly specialized feeding sites (NFS) in infected plant roots from which they withdraw nutrients. In order to establish these NFS, it is thought that the nematodes manipulate the molecular and physiological pathways of their hosts. Evidence is accumulating that the plant signalling molecule auxin is involved in the initiation and development of the feeding sites of sedentary plant-parasitic nematodes. Intercellular transport of auxin is essential for various aspects of plant growth and development. Here, we analysed the spatial and temporal expression of PIN auxin transporters during the early events of NFS establishment using promoter-GUS/GFP fusion lines. Additionally, single and double pin mutants were used in infection studies to analyse the role of the different PIN proteins during cyst nematode infection. Based on our results, we postulate a model in which PIN1-mediated auxin transport is needed to deliver auxin to the initial syncytial cell, whereas PIN3 and PIN4 distribute the accumulated auxin laterally and are involved in the radial expansion of the NFS. Our data demonstrate that cyst nematodes are able to hijack the auxin distribution network in order to facilitate the infection process. © 2009 Grunewald et al","lang":"eng"}],"intvolume":"         5","extern":1,"date_published":"2009-01-01T00:00:00Z","publication":"PLoS Pathogens","month":"01","year":"2009","doi":" 10.1371/journal.ppat.1000266","date_updated":"2021-01-12T07:40:40Z","date_created":"2018-12-11T12:01:03Z","publist_id":"3656","type":"journal_article","title":"Parasitic nematodes modulate PIN mediated auxin transport to facilitate infection","_id":"3046","publication_status":"published","status":"public"},{"quality_controlled":0,"volume":57,"citation":{"apa":"Titapiwatanakun, B., Blakeslee, J., Bandyopadhyay, A., Yang, H., Mravec, J., Sauer, M., … Murphy, A.

The PIN and ABCB transport proteins, best represented by PIN1 and ABCB19 (PGP19), have been shown to coordinately regulate auxin efflux. When PIN1 and ABCB19 coincide on the plasma membrane, their interaction enhances the rate and specificity of auxin efflux and the dynamic cycling of PIN1 is reduced. However, ABCB19 function is not regulated by the dynamic cellular trafficking mechanisms that regulate PIN1 in apical tissues, as localisation of ABCB19 on the plasma membrane was not inhibited by short-term treatments with latrunculin B, oryzalin, brefeldin A (BFA) or wortmannin - all of which have been shown to alter PIN1 and/or PIN2 plasma membrane localisation. When taken up by endocytosis, the styryl dye FM4-64 labels diffuse rather than punctuate intracellular bodies in abcb19 (pgp19), and some aggregations of PIN1 induced by short-term BFA treatment did not disperse after BFA washout in abcb19. Although the subcellular localisations of ABCB19 and PIN1 in the reciprocal mutant backgrounds were like those in wild type, PIN1 plasma membrane localisation in abcb19 roots was more easily perturbed by the detergent Triton X-100, but not other non-ionic detergents. ABCB19 is stably associated with sterol/sphingolipid-enriched membrane fractions containing BIG/TIR3 and partitions into Triton X-100 detergent-resistant membrane (DRM) fractions. In the wild type, PIN1 was also present in DRMs, but was less abundant in abcb19 DRMs. These observations suggested a rationale for the observed lack of auxin transport activity when PIN1 is expressed in a non-plant heterologous system. PIN1 was therefore expressed in Schizosaccharomyces pombe, which has plant-like sterol-enriched microdomains, and catalysed auxin transport in these cells. These data suggest that ABCB19 stabilises PIN1 localisation at the plasma membrane in discrete cellular subdomains where PIN1 and ABCB19 expression overlaps.

Membrane proteins of the PIN-FORMED (PIN) family exhibit polar localization in plant cells and facilitate cellular efflux of the plant hormone auxin, thereby regulating multiple developmental processes [1, 2]. PIN proteins undergo constitutive endocytosis and GNOM ARF GEF-dependent recycling [3-5], and their localization is under extensive regulation by developmental and environmental cues [6-9]. We designed a fluorescence imaging-based screen to identify Arabidopsis thaliana mutants defective in internalization of proteins including PINs from the plasma membrane. We identified three mutant loci, BFA-visualized endocytic trafficking defective1 (ben1) through ben3 that do not efficiently accumulate PIN1-GFP in intracellular compartments after inhibition of recycling and secretion by fungal toxin brefeldin A (BFA). Fine mapping revealed that BEN1 encodes an ARF GEF vesicle trafficking regulator from the functionally uncharacterized BIG class. ben1 mutant has been previously implicated in pathogen response [10] and shows cell polarity, BFA sensitivity, and growth defects. BEN1 is involved in endocytosis of plasma membrane proteins and localizes to early endocytic compartments distinct from GNOM-positive endosomes.

The phytohormones auxin and cytokinin (CK) are important regulators of the developmental fate of pluripotent plant cells. However, the molecular nature of their interaction(s) in control of plant organogenesis is largely unknown. Here, we show that CK modulates auxin-induced organogenesis (AIO) via regulation of the efflux-dependent intercellular auxin distribution. We used the hypocotyl explants-based in vitro system to study the mechanism underlying de novo organogenesis. We show that auxin, but not CK, is capable of triggering organogenesis in hypocotyl explants. The AIO is accompanied by endogenous CK production and tissue-specific activation of CK signaling. CK affects differential auxin distribution, and the CK-mediated modulation of organogenesis is simulated by inhibition of polar auxin transport. CK reduces auxin efflux from cultured tobacco cells and regulates expression of auxin efflux carriers from the PIN family in hypocotyl explants. Moreover, endogenous CK levels influence PIN transcription and are necessary to maintain intercellular auxin distribution in planta. Based on these findings, we propose a model in which auxin acts as a trigger of the organogenic processes, whose output is modulated by the endogenously produced CKs. We propose that an important mechanism of this CK action is its effect on auxin distribution via regulation of expression of auxin efflux carriers.","lang":"eng"}],"publisher":"National Academy of Sciences"},{"publist_id":"3652","date_created":"2018-12-11T12:01:04Z","date_updated":"2021-01-12T07:40:42Z","doi":"10.1073/pnas.0900060106","year":"2009","status":"public","publication_status":"published","_id":"3050","type":"journal_article","title":"Cytokinin regulates root meristem activity via modulation of the polar auxin transport","quality_controlled":0,"volume":106,"issue":"11","citation":{"ieee":"K.

Typically, in certain developmental processes more than 1 hormone is implicated and, thus, coordination of their overlapping activities is crucial for correct plant development. However, molecular mechanisms underlying the hormonal crosstalk are only poorly understood. Multiple hormones including cytokinin and auxin have been implicated in the regulation of root development. Here we dissect the roles of cytokinin in modulating growth of the primary root. We show that cytokinin effect on root elongation occurs through ethylene signaling whereas cytokinin effect on the root meristem size involves ethylene-independent modulation of transport-dependent asymmetric auxin distribution. Exogenous or endogenous modification of cytokinin levels and cytokinin signaling lead to specific changes in transcription of several auxin efflux carrier genes from the PIN family having a direct impact on auxin efflux from cultured cells and on auxin distribution in the root apex. We propose a novel model for cytokinin action in regulating root growth: Cytokinin influences cell-to-cell auxin transport by modification of expression of several auxin transport components and thus modulates auxin distribution important for regulation of activity and size of the root meristem."}],"publisher":"National Academy of Sciences"},{"citation":{"ama":"Weijers D, Friml J.

Various environmental and endogenous signals can be integrated into changes in auxin distribution through their effects on local auxin biosynthesis and intercellular auxin transport. Individual cells interpret auxin largely by a nuclear signaling pathway that involves the F box protein TIR1 acting as an auxin receptor. Auxin-dependent TIR1 activity leads to ubiquitination-based degradation of transcriptional repressors and complex transcriptional reprogramming. Thus, auxin appears to be a versatile trigger of preprogrammed developmental changes in plant cells.","lang":"eng"}],"external_id":{"pmid":["    19303845"]},"date_published":"2009-03-20T00:00:00Z","publication":"Cell","year":"2009","doi":"10.1016/j.cell.2009.03.001","date_created":"2018-12-11T12:01:05Z","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"title":"Auxin: A trigger for change in plant development","type":"journal_article","publication_status":"published","page":"1005 - 1016","citation":{"ieee":"S.

To compensate for the absence of a cardiovascular system, plants have evolved specialized transport pathways to distribute signals and nutrients. The main transport streams include the xylem flow of the nutrients from the root to the shoot and the phloem flow of materials from the photosynthetic active tissues. These long-distance transport processes are complemented by several intercellular transport mechanisms (apoplastic, symplastic and transcellular transport). A prominent example of transcellular flow is transport of the phytohormone auxin within tissues. The process is mediated by influx and efflux carriers, whose polar localization in the plasma membrane determines the directionality of the flow. This polar auxin transport generates auxin maxima and gradients within tissues that are instrumental in the diverse regulation of various plant developmental processes, including embryogenesis, organogenesis, vascular tissue formation and tropisms."}],"publisher":"Nature Publishing Group"}]
