The combined measurement of current and resistance allows for investigating the interaction of mass- and charge-transport processes, which determine the local rate distribution across the domain of channels and ribs. Therewith, the influence of relevant operating parameters such as reactant composition, dew points, and cell compression on local current generation is investigated. The results show that the distribution of water and oxidant across the channel and rib are the main reasons for significant current gradients on a scale smaller than a millimeter. Humidity variation mainly affects the membrane resistance under the channel, while reactant concentration predominantly influences current generation under the rib-covered cell area."}],"issue":"3"},{"date_created":"2018-12-11T11:48:19Z","page":"943 - 953","doi":"10.1007/978-3-642-10631-6_95","conference":{"name":"ISAAC: International Symposium on Algorithms and Computation"},"publication_status":"published","date_published":"2009-01-01T00:00:00Z","language":[{"iso":"eng"}],"oa_version":"None","type":"conference","article_processing_charge":"No","publist_id":"6903","volume":"5878 LNCS","citation":{"chicago":"Alistarh, Dan-Adrian, Seth Gilbert, Rachid Guerraoui, and Corentin Travers. “Of Choices, Failures and Asynchrony: The Many Faces of Set Agreement,” 5878 LNCS:943–53.

The impossibility of fault-tolerant set agreement in asynchronous networks is one of the seminal results in distributed computing. The complexity of set agreement in synchronous networks has also been a significant research challenge. Real systems, however, are neither purely synchronous nor purely asynchronous. Rather, they tend to alternate between periods of synchrony and periods of asynchrony. In this paper, we analyze the complexity of set agreement in a &quot;partially synchronous&quot; setting, presenting the first (asymptotically) tight bound on the complexity of set agreement in such systems. We introduce a novel technique for simulating, in fault-prone asynchronous shared memory, executions of an asynchronous and failure-prone messagepassing system in which some fragments appear synchronous to some processes. We use this technique to derive a lower bound on the round complexity of set agreement in a partially synchronous system by a reduction from asynchronous wait-free set agreement. We also present an asymptotically matching algorithm that relies on a distributed asynchrony detection mechanism to decide as soon as possible during periods of synchrony. By relating environments with differing degrees of synchrony, our simulation technique is of independent interest. In particular, it allows us to obtain a new lower bound on the complexity of early deciding k-set agreement complementary to that of [12], and to re-derive the combinatorial topology lower bound of [13] in an algorithmic way."}],"acknowledgement":"Corentin Travers was supposrted in part by a Sam & Cecilia Neaman Fellowship","date_updated":"2023-02-23T13:10:05Z","_id":"752","author":[{"full_name":"Alistarh, Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","last_name":"Alistarh","first_name":"Dan-Adrian","orcid":"0000-0003-3650-940X"},{"first_name":"Seth","last_name":"Gilbert","full_name":"Gilbert, Seth"},{"full_name":"Guerraoui, Rachid","first_name":"Rachid","last_name":"Guerraoui"},{"last_name":"Travers","first_name":"Corentin","full_name":"Travers, Corentin"}],"title":"Of choices, failures and asynchrony: the many faces of set agreement","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","publisher":"Springer","alternative_title":["LNCS"],"month":"01"},{"language":[{"iso":"eng"}],"date_published":"2009-04-01T00:00:00Z","type":"journal_article","oa_version":"None","date_created":"2020-04-30T11:01:57Z","page":"1639-1648","publication":"Genetics","publication_status":"published","doi":"10.1534/genetics.108.086801","quality_controlled":"1","volume":181,"citation":{"ista":"Robinson MR, Wilson AJ, Pilkington JG, Clutton-Brock TH, Pemberton JM, Kruuk LEB. 2009.

The implication of this observation is that the environmental response may influence the evolution of traits in the wild. Here, we examined how the genetic architecture of a suite of sexually dimorphic traits changed as a function of environmental conditions in an unmanaged population of Soay sheep (Ovis aries) on the island of Hirta, St. Kilda, northwest Scotland. We examined the stability of phenotypic, genetic, and environmental (residual) covariance in males during the first year of life between horn length, body weight, and parasite load in environments of different quality. We then examined the same covariance structures across environments within and between the adult sexes. We found significant genotype-by-environment interactions for lamb male body weight and parasite load, leading to a change in the genetic correlation among environments. Horn length was genetically correlated with body weight in males but not females and the genetic correlation among traits within and between the sexes was dependent upon the environmental conditions experienced during adulthood. Genetic correlations were smaller in more favorable environmental conditions, suggesting that in good environments, loci are expressed that have sex-specific effects. The reduction in genetic correlation between the sexes may allow independent evolutionary trajectories for each sex. This study demonstrates that the genetic architecture of traits is not stable under temporally varying environments and highlights the fact that evolutionary processes may depend largely upon ecological conditions.\r\nENVIRONMENTAL heterogeneity has long been recognized as an important factor influencing the evolution of fitness-related traits in the wild (Roff 2002). The evolution of a trait depends upon the selection upon it, underlying genetic variation, and to a large degree the genetic relationships with other traits (Lynch and Walsh 1998). There is evidence that selection can vary considerably from year to year (Price et al. 1984; Robinson et al. 2008) and genetic variability in quantitative traits can change in response to environmental conditions (Hoffmann and Merilä 1999; Charmantier and Garant 2005). However, we know surprisingly little about the influence of environmental conditions on genetic correlations between traits in wild populations. Laboratory evidence suggests that the environment may influence genetic relationships between traits (Sgrò and Hoffmann 2004), but estimates obtained in a controlled or in an arbitrary range of conditions show a lack of concordance with those obtained in wild habitats (Conner et al. 2003). As a result, laboratory and environment-specific estimates of genetic correlations can make predictions for a trait's evolution, but these are valid only for the environment in which they were measured. Therefore, at present, it is difficult to generalize about the evolution of a trait that is expressed in populations that experience variable environmental conditions (Steppan et al. 2002).\r\nThe influence of changing environmental conditions on the G matrix (the matrix of additive genetic variance and covariances corresponding to a set of traits) has been the focus of theoretical quantitative genetic studies (e.g., Jones et al. 2003). There is evidence of genotype-by-environment interaction for many traits expressed in wild populations (Charmantier and Garant 2005) and thus we may also expect that associations between traits may depend upon the environmental conditions encountered by an individual. Genetic correlations among traits may arise from pleiotropy, where a given locus affects more than one trait (Cheverud 1988; Lynch and Walsh 1998), which may limit the potential for those traits to evolve independently. There has recently been much interest in assessing genetic correlations between the sexes (Rice and Chippindale 2001; Foerster et al. 2007; Poissant et al. 2008), but all of these predictions have also been made in average environmental conditions. For sexually dimorphic traits, expectations of between-sex genetic correlations are unclear (Lande 1980; Badyaev 2002). We might expect that the genetic determination of a trait and the patterns of genetic covariance between traits may differ both within and between the sexes, producing the differences in trait growth that are commonly observed (Lande 1980; Badyaev 2002; Roff 2002), but so far evidence suggests that genetic expression in both sexes is influenced by the same developmental pathway (Roff 2002; Jensen et al. 2003; Parker and Garant 2005). However, to our knowledge, no study has yet determined whether genetic correlations, both within and between the sexes, vary across gradients of the environmental conditions encountered by individuals in the wild (Garant et al. 2008).\r\nThis study aims to assess the stability of phenotypic, genetic, and environmental (residual) associations between traits, within and between the sexes, across a range of environmental conditions experienced by a wild population. We focus on the traits of horn length, body weight, and parasite load in a feral population of Soay sheep (Ovis aries) from the island of Hirta, St. Kilda, United Kingdom. Weather conditions, population density, and consequently resource availability fluctuate from year to year, providing substantial differences between individuals in the environments they experience and thus their survival rates (Clutton-Brock and Pemberton 2004). These varying conditions, combined with a large pedigree and extensive repeated morphological measures, provide an excellent opportunity to assess the potential effects of environmental heterogeneity on genetic architecture of traits. Previous studies on this population have shown additive genetic variance for many morphological traits (Milner et al. 2000; Coltman et al. 2001; Wilson et al. 2005), genetic correlations between traits (Coltman et al. 2001), and genotype-by-environment interactions for birth weight (Wilson et al. 2006). Here we apply a random regression animal model approach to assess the extent to which quantitative genetic parameters of a range of morphological traits measured during life vary as a function of environmental conditions. We then extend this methodology to the multivariate case, testing whether the phenotypic covariance structure, and the underlying G matrix, depends on the environmental conditions experienced. Since the traits considered here are known to be sexually dimorphic and there are differences in trait growth and survival across ages, we look at sex-specific traits in lambs and then across all ages.","lang":"eng"}],"month":"04","title":"The impact of environmental heterogeneity on genetic architecture in a wild population of soay sheep","publication_identifier":{"issn":["0016-6731","1943-2631"]},"status":"public","publisher":"Genetics Society of America","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"main_file_link":[{"url":"http://arxiv.org/abs/0904.2638","open_access":"1"}],"intvolume":"      5643","citation":{"short":"R.

An observation-based strategy relies on partial information about the history of a play, namely, on the past sequence of observa- tions. We consider the qualitative analysis problem: given a POMDP with an omega-regular objective, whether there is an observation-based strategy to achieve the objective with probability 1 (almost-sure winning), or with positive probability (positive winning). 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."}],"day":"09","year":"2009","author":[{"last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu"},{"last_name":"Doyen","first_name":"Laurent","full_name":"Doyen, Laurent"},{"full_name":"Henzinger, Thomas A","orcid":"0000−0002−2985−7724","first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger"}],"file":[{"access_level":"open_access","creator":"system","checksum":"04d9cc065cc19598a4e8631c47f1a562","file_id":"5486","date_created":"2018-12-12T11:53:25Z","file_name":"IST-2009-0001_IST-2009-0001.pdf","date_updated":"2020-07-14T12:46:43Z","file_size":342088,"content_type":"application/pdf","relation":"main_file"}],"_id":"5395","publisher":"IST Austria","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Qualitative analysis of partially-observable Markov decision processes","publication_identifier":{"issn":["2664-1690"]},"oa":1,"month":"09","alternative_title":["IST Austria Technical Report"]},{"publisher":"Cold Spring Harbor Laboratory Press","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"The human CDK8 subcomplex is a molecular switch that controls Mediator coactivator function","oa":1,"month":"02","date_updated":"2021-01-12T08:05:32Z","abstract":[{"text":"The human CDK8 subcomplex (CDK8, cyclin C, Med12, and Med13) negatively regulates transcription in ways not completely defined; past studies suggested CDK8 kinase activity was required for its repressive function. Using a reconstituted transcription system together with recombinant or endogenous CDK8 subcomplexes, we demonstrate that, in fact, Med12 and Med13 are critical for subcomplex-dependent repression, whereas CDK8 kinase activity is not. A hallmark of activated transcription is efficient reinitiation from promoter-bound scaffold complexes that recruit a series of pol II enzymes to the gene. Notably, the CDK8 submodule strongly represses even reinitiation events, suggesting a means to fine tune transcript levels. Structural and biochemical studies confirm the CDK8 submodule binds the Mediator leg/tail domain via the Med13 subunit, and this submodule-Mediator association precludes pol II recruitment. Collectively, these results reveal the CDK8 subcomplex functions as a simple switch that controls the Mediator-pol II interaction to help regulate transcription initiation and reinitiation events. As Mediator is generally required for expression of protein-coding genes, this may reflect a common mechanism by which activated transcription is shut down in human cells.","lang":"eng"}],"issue":"4","day":"15","year":"2009","extern":"1","author":[{"first_name":"Matthew","last_name":"Knuesel","full_name":"Knuesel, Matthew"},{"first_name":"Krista","last_name":"Meyer","full_name":"Meyer, Krista"},{"last_name":"Bernecky","id":"2CB9DFE2-F248-11E8-B48F-1D18A9856A87","first_name":"Carrie A","orcid":"0000-0003-0893-7036","full_name":"Bernecky, Carrie A"},{"full_name":"Taatjes, Dylan","first_name":"Dylan","last_name":"Taatjes"}],"_id":"599","publist_id":"7211","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2648653/","open_access":"1"}],"article_processing_charge":"No","intvolume":"        23","volume":23,"citation":{"ista":"Knuesel M, Meyer K, Bernecky C, Taatjes D. 2009.

Here we show that some Caenorhabditis elegans wild strains switch between two foraging behaviours in response to subtle changes in ambient oxygen. This finely tuned switch is conferred by a naturally variable hexacoordinated globin, GLB-5. GLB-5 acts with the atypical soluble guanylate cyclases1,2,3, which are a different type of oxygen binding protein, to tune the dynamic range of oxygen-sensing neurons close to atmospheric (21%) concentrations. Calcium imaging indicates that one group of these neurons is activated when oxygen rises towards 21%, and is inhibited as oxygen drops below 21%. The soluble guanylate cyclase GCY-35 is required for high oxygen to activate the neurons; GLB-5 provides inhibitory input when oxygen decreases below 21%. Together, these oxygen binding proteins tune neuronal and behavioural responses to a narrow oxygen concentration range close to atmospheric levels. The effect of the glb-5 gene on oxygen sensing and foraging is modified by the naturally variable neuropeptide receptor npr-1 (refs 4, 5), providing insights into how polygenic variation reshapes neural circuit function."}],"pmid":1,"date_updated":"2021-01-12T08:06:20Z","extern":"1","year":"2009","day":"23","author":[{"last_name":"Persson","first_name":"Annelie","full_name":"Persson, Annelie"},{"first_name":"Einav","last_name":"Gross","full_name":"Gross, Einav"},{"last_name":"Laurent","first_name":"Patrick","full_name":"Laurent, Patrick"},{"first_name":"Karl Emanuel","last_name":"Busch","full_name":"Busch, Karl Emanuel"},{"full_name":"Bretes, Hugo","first_name":"Hugo","last_name":"Bretes"},{"last_name":"de Bono","id":"4E3FF80E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8347-0443","first_name":"Mario","full_name":"de Bono, Mario"}],"_id":"6144","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","publisher":"Springer Nature","status":"public","publication_identifier":{"issn":["0028-0836","1476-4687"]},"title":"Natural variation in a neural globin tunes oxygen sensing in wild Caenorhabditis elegans","month":"04"},{"publisher":"Elsevier","status":"public","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","title":"Coordinated regulation of foraging and metabolism in C. elegans by RFamide neuropeptide signaling","publication_identifier":{"issn":["1550-4131"]},"month":"04","date_updated":"2021-01-12T08:06:20Z","pmid":1,"issue":"4","day":"08","year":"2009","extern":"1","author":[{"full_name":"Cohen, Merav","last_name":"Cohen","first_name":"Merav"},{"full_name":"Reale, Vincenzina","last_name":"Reale","first_name":"Vincenzina"},{"full_name":"Olofsson, Birgitta","last_name":"Olofsson","first_name":"Birgitta"},{"first_name":"Andrew","last_name":"Knights","full_name":"Knights, Andrew"},{"full_name":"Evans, Peter","first_name":"Peter","last_name":"Evans"},{"first_name":"Mario","orcid":"0000-0001-8347-0443","id":"4E3FF80E-F248-11E8-B48F-1D18A9856A87","last_name":"de Bono","full_name":"de Bono, Mario"}],"_id":"6145","external_id":{"pmid":["19356718"]},"citation":{"ista":"Cohen M, Reale V, Olofsson B, Knights A, Evans P, de Bono M. 2009.

Such positive photoconductance is observed in both bulk and nanostructured5,6 photoconductors. Here we describe a class of nanoparticle-based materials whose conductivity can either increase or decrease on irradiation with visible light of wavelengths close to the particles’ surface plasmon resonance. The remarkable feature of these plasmonic materials is that the sign of the conductivity change and the nature of the electron transport between the nanoparticles depend on the molecules comprising the self-assembled monolayers (SAMs)7,8 stabilizing the nanoparticles. For SAMs made of electrically neutral (polar and non-polar) molecules, conductivity increases on irradiation. If, however, the SAMs contain electrically charged (either negatively or positively) groups, conductivity decreases. The optical and electrical characteristics of these previously undescribed inverse photoconductors can be engineered flexibly by adjusting the material properties of the nanoparticles and of the coating SAMs. In particular, in films comprising mixtures of different nanoparticles or nanoparticles coated with mixed SAMs, the overall photoconductance is a weighted average of the changes induced by the individual components. These and other observations can be rationalized in terms of light-induced creation of mobile charge carriers whose transport through the charged SAMs is inhibited by carrier trapping in transient polaron-like states9,10. The nanoparticle-based photoconductors we describe could have uses in chemical sensors and/or in conjunction with flexible substrates."}],"issue":"7253","date_updated":"2023-08-08T09:00:59Z","year":"2009","_id":"13418","scopus_import":"1","citation":{"ieee":"H.
