A specialized two-cell stack with advanced localized diagnostics was developed and used to analyze the mechanism and effect of cell-to-cell coupling as a result of operationally relevant variations in reactant feed flow. Contributions to overall and local voltage changes with respect to uniformly operated cells are scrutinized. Unequal operation of the cells causes in-plane current in the bipolar plate to redistribute current and result in inhomogeneous polarization. Both increasing and decreasing polarization along the air-flow path reduces cell power as compared to isopotential operation. A two-dimensional model based on a commercial computational fluid dynamics code is used to back and extend the experimental results to more general cases. Furthermore, the experimental setup presented allowed for the first time to perform simultaneous localized electrochemical impedance spectroscopy beyond the single-cell level. The mechanism of mutual cell interaction on local and integral spectra is revealed. Results show that virtually identical operation of the cells is essential to obtain meaningful integral spectra."}],"publication_status":"published","date_created":"2020-01-15T12:21:47Z","intvolume":"       155","status":"public","issue":"7","year":"2008","date_updated":"2021-01-12T08:13:03Z","date_published":"2008-05-08T00:00:00Z","author":[{"last_name":"Freunberger","full_name":"Freunberger, Stefan Alexander","first_name":"Stefan Alexander","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","orcid":"0000-0003-2902-5319"},{"last_name":"Schneider","full_name":"Schneider, Ingo A.","first_name":"Ingo A."},{"full_name":"Sui, Pang-Chieh","last_name":"Sui","first_name":"Pang-Chieh"},{"full_name":"Wokaun, Alexander","last_name":"Wokaun","first_name":"Alexander"},{"first_name":"Nedjib","full_name":"Djilali, Nedjib","last_name":"Djilali"},{"last_name":"Büchi","full_name":"Büchi, Felix N.","first_name":"Felix N."}],"article_processing_charge":"No","day":"08","publisher":"The Electrochemical Society","extern":"1","_id":"7321","language":[{"iso":"eng"}],"article_number":"B704","citation":{"apa":"Freunberger, S.

Beside ensuring sufficient electrical and thermal contact between the whole electrode area and the flow field, these typically 200–400 μm thick porous structures enable the access of educts to the electrode area which would be occluded by the flow field lands if the flow field is directly attached to the electrode. Hence, the characterisation of properties pertaining to mass transport of educts and products through these structures is indispensable whilst examining the contribution of the GDLs to the overall electrochemical characteristics of a MEA. A fast and cost effective method to measure the effective diffusivity of a GDL is presented. Electrochemical impedance spectroscopy is applied to measure the effective ionic conductivity of an electrolyte-soaked GDL. Taking advantage of the analogy between Ficks and Ohms law, this provides a measure for the effective diffusivity. The method is described in detail, including experimental as well as theoretical aspects, and selected results, highlighting the anisotropy and dependence on the degree of compression, are shown. Moreover, a two-dimensional model consisting of regularly spaced ellipses is developed to represent the porous structure of the GDL, and by using conformal maps, the agreement between this model and experiment with respect to the sensitivity of the effective diffusivity towards compression is shown."}],"doi":"10.1016/j.jelechem.2007.09.014","quality_controlled":"1","type":"journal_article","oa_version":"None","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"01","volume":612,"article_type":"original","title":"Electrochemical diffusimetry of fuel cell gas diffusion layers","page":"63-77","publication":"Journal of Electroanalytical Chemistry","publication_identifier":{"issn":["1572-6657"]},"citation":{"ama":"Kramer D, Freunberger SA, Flückiger R, et al.

We show that the data are compatible with the assumption of s = 0, although moderate amounts of selection acting on this mutation cannot be excluded.

The open nature of the Wikipedia has been key to its success, but has also created a challenge: how can readers develop an informed opinion on its reliability? We propose a system that computes quantitative values of trust for the text in Wikipedia articles; these trust values provide an indication of text reliability.\n\nThe system uses as input the revision history of each article, as well as information about the reputation of the contributing authors, as provided by a reputation system. The trust of a word in an article is computed on the basis of the reputation of the original author of the word, as well as the reputation of all authors who edited text near the word. The algorithm computes word trust values that vary smoothly across the text; the trust values can be visualized using varying text-background colors. The algorithm ensures that all changes to an article's text are reflected in the trust values, preventing surreptitious content changes.\n\nWe have implemented the proposed system, and we have used it to compute and display the trust of the text of thousands of articles of the English Wikipedia. To validate our trust-computation algorithms, we show that text labeled as low-trust has a significantly higher probability of being edited in the future than text labeled as high-trust.","lang":"eng"}],"date_created":"2018-12-11T12:03:40Z","doi":"10.1145/1822258.1822293","type":"conference","quality_controlled":0,"status":"public","date_published":"2008-09-10T00:00:00Z","date_updated":"2021-01-12T07:43:53Z","year":"2008","author":[{"first_name":"B Thomas","full_name":"Adler, B Thomas","last_name":"Adler"},{"full_name":"Krishnendu Chatterjee","last_name":"Chatterjee","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu"},{"first_name":"Luca","last_name":"De Alfaro","full_name":"de Alfaro, Luca"},{"full_name":"Faella, Marco","last_name":"Faella","first_name":"Marco"},{"first_name":"Ian","last_name":"Pye","full_name":"Pye, Ian"},{"first_name":"Vishwanath","last_name":"Raman","full_name":"Raman, Vishwanath"}]},{"title":"Robust content-driven reputation","month":"10","publist_id":"2885","conference":{"name":"AISec: Artificial Intelligence and Security"},"acknowledgement":"This research has been partially supported by the CITRIS: Center for Information Technology Research in the Interest of Society.","page":"33 - 42","citation":{"ama":"Chatterjee K, De Alfaro L, Pye I.

Existing content-driven systems are prone to Sybil attacks, in which multiple identities, controlled by the same person, perform coordinated actions to increase their reputation. We show that content-driven reputation systems can be made resistant to such attacks by taking advantage of thefact that the reputation increments and decrements depend on content modifications, which are visible to all. We present an algorithm for content-driven reputation that prevents a set of identities from increasing their maximum reputation without doing any useful work. Here, work is considered useful if it causes content to evolve in a direction that is consistent with the actions of high-reputation users. We argue that the content modifications that require no effort, such as the insertion or deletion of arbitrary text, are invariably non-useful. We prove a truthfullness result for the resulting system, stating that users who wish to perform a contribution do not gain by employing complex contribution schemes, compared to simply performing the contribution at once. In particular, splitting the contribution in multiple portions, or employing the coordinated actions of multiple identities, do not yield additional reputation. Taken together, these results indicate that content-driven systems can be made robust with respect to Sybil attacks.

These metrics capture the similarity of states with respect to quantitative specifications written in the quantitative μ-calculus and related probabilistic logics.\r\nWe present algorithms for computing the metrics on Markov decision processes (MDPs), turn- based stochastic games, and concurrent games. For turn-based games and MDPs, we provide a polynomial-time algorithm based on linear programming for the computation of the one-step metric distance between states. The algorithm improves on the previously known exponential-time algo- rithm based on a reduction to the theory of reals. We then present PSPACE algorithms for both the decision problem and the problem of approximating the metric distance between two states, matching the best known bound for Markov chains. For the bisimulation kernel of the metric, which corresponds to probabilistic bisimulation, our algorithm works in time O(n4) for both turn-based games and MDPs; improving the previously best known O(n9 · log(n)) time algorithm for MDPs. For a concurrent game G, we show that computing the exact distance between states is at least as hard as computing the value of concurrent reachability games and the square-root-sum problem in computational geometry. We show that checking whether the metric distance is bounded by a rational r, can be accomplished via a reduction to the theory of real closed fields, involving a\r\nformula with three quantifier alternations, yielding O(|G|O(|G|5)) time complexity, improving the previously known reduction with O(|G|O(|G|7)) time complexity.

This arises from the backwards shift in cell firing relative to local theta oscillations (phase precession). Here we demonstrate phase precession during place-field crossings in an open-field foraging task. This produced spike sequences in each theta cycle that disambiguate the rat's trajectory through two-dimensional space and can be used to predict movement direction. Furthermore, position and movement direction were maximally predicted from firing in the early and late portions of the theta cycle, respectively.

This cofiring increase depended on the number of times that cells fired together with short latencies ( &lt; 50 ms) during exploration, and was strongest between cells representing the most visited places. This is indicative of a Hebbian learning rule in which changes in firing associations between cells are determined by the number of waking coincident firing events.

Ivy cells express nitric oxide synthase, neuropeptide Y, and high levels of GABA(A) receptor alpha 1 subunit; they discharge at a low frequency with wide spikes in vivo, yet are distinctively phase-locked to behaviorally relevant network rhythms including theta, gamma, and ripple oscillations. Paired recordings in vitro showed that Ivy cells receive depressing EPSPs from pyramidal cells, which in turn receive slowly rising and decaying inhibitory input from Ivy cells.

Furthermore, it has been suggested that the encoding of these and other types of temporal memory sequences is organized by gamma oscillations nested within theta oscillations. Here, we examined whether gamma-related firing of place cells permits such discrete temporal coding. We found that gamma-modulated CA1 pyramidal cells separated into two classes on the basis of gamma firing phases during waking theta periods. These groups also differed in terms of their spike waveforms, firing rates, and burst firing tendency. During gamma oscillations one group's firing became restricted to theta phases associated with the highest gamma power. Consequently, on the linear track, cells in this group often failed to fire early in theta-phase precession (as the rat entered the place field) if gamma oscillations were present. The second group fired throughout the theta cycle during gamma oscillations, and maintained gamma-modulated firing at different stages of theta-phase precession. Our results suggest that the two different pyramidal cell classes may support different types of population codes within a theta cycle: one in which spike sequences representing movement trajectories occur across subsequent gamma cycles nested within each theta cycle, and another in which firing in synchronized gamma discharges without temporal sequences encode a representation of location. We propose that gamma oscillations during theta-phase precession organize the mnemonic recall of population patterns representing places and movement paths.","lang":"eng"}],"status":"public","page":"2274 - 2286","publication":"Journal of Neuroscience","title":"Gamma oscillatory firing reveals distinct populations of pyramidal cells in the CA1 region of the hippocampus","publist_id":"2847","volume":28,"month":"02","day":"27","publisher":"Society for Neuroscience","_id":"3537","extern":1,"citation":{"chicago":"Senior, Timothy, John Huxter, Kevin Allen, Joseph O’Neill, and Jozsef L Csicsvari. “Gamma Oscillatory Firing Reveals Distinct Populations of Pyramidal Cells in the CA1 Region of the Hippocampus.” <i>Journal of Neuroscience</i>.

Abnormal beta oscillations and motor symptoms are concomitantly and acutely suppressed by dopaminergic therapies, suggesting that these inappropriate rhythms might also emerge acutely from disrupted dopamine transmission. The neural basis of these abnormal beta oscillations is unclear, and how they might compromise information processing, or how they arise, is unknown. Using a 6-hydroxydopamine-lesioned rodent model of PD, we demonstrate that beta oscillations are inappropriately exaggerated, compared with controls, in a brain-state-dependent manner after chronic dopamine loss. Exaggerated beta oscillations are expressed at the levels of single neurons and small neuronal ensembles, and are focally present and spatially distributed within STN. They are also expressed in synchronous population activities, as evinced by oscillatory local field potentials, in STN and cortex. Excessively synchronized beta oscillations reduce the information coding capacity of STN neuronal ensembles, which may contribute to parkinsonian motor impairment. Acute disruption of dopamine transmission in control animals with antagonists of D-1/D-2 receptors did not exaggerate STN or cortical beta oscillations. Moreover, beta oscillations were not exaggerated until several days after 6-hydroxydopamine injections. Thus, contrary to predictions, abnormally amplified beta oscillations in cortico-STN circuits do not result simply from an acute absence of dopamine receptor stimulation, but are instead delayed sequelae of chronic dopamine depletion. Targeting the plastic processes underlying the delayed emergence of pathological beta oscillations after continuing dopaminergic dysfunction may offer considerable therapeutic promise."}],"date_created":"2018-12-11T12:03:53Z","publication_status":"published","intvolume":"        28","quality_controlled":0,"type":"journal_article","status":"public"},{"extern":1,"_id":"3577","publisher":"Springer","day":"01","citation":{"apa":"Biasotti, S., Attali, D., Boissonnat, J., Edelsbrunner, H., Elber, G., Mortara, M., … Veltkam, R.

Recent evidence shows that endocytic turnover of E-cadherin regulates the migration of mesendodermal cells during zebrafish gastrulation by modulating their adhesive interactions with neighboring cells.

In this case it is very hard to ensure that an optimization algorithm can be smoothly scaled up from a low-dimensional optimization problem to the one with a high dimensionality. This paper addresses the scalability issue of a novel optimization algorithm inspired by the Shifting Balance Theory (SBT) of evolution in population genetics. Toward this end, a cluster-based WSN is employed in this paper as a benchmark to perform a comparative study. The total energy consumption is minimized under the required quality of service by jointly optimizing the transmission power and rate for each sensor node. The results obtained by the SBT-based algorithm are compared with the Metropolis algorithm (MA) and currently popular particle swarm optimizer (PSO) to assess the scaling performance of the three algorithms against the same WSN optimization problem.","lang":"eng"}],"intvolume":"      5216","publication_status":"published","date_created":"2018-12-11T12:04:10Z","status":"public","page":"249 - 260","title":" Scalability of a novel shifting balance theory-based optimization algorithm: A comparative study on a cluster-based wireless sensor network","conference":{"name":"IECS: International Conference on Evolvable Systems"},"volume":5216,"publist_id":"2783","month":"09","day":"08","publisher":"Springer","_id":"3600","extern":1,"citation":{"apa":"Yang, E., Barton, N.

Given the ubiquity of assortative mating in nature, why and how it has evolved remain open questions. Here we attempt to answer these questions in those cases where the trait under assortment is the same in males and females. We consider the most favorable scenario for assortment to evolve, where the same trait is under assortment and viability selection. We find conditions for assortment to evolve using a multilocus formalism in a haploid population. Our results show how epistasis in fitness between the loci that control the focal trait is crucial for assortment to evolve. We then assume specific forms of assortment in haploids and diploids and study the limiting cases of selective and nonselective mating. We find that selection for increased assortment is weak and that where increased assortment is costly, it does not invade."}],"publication_status":"published","intvolume":"       171","date_created":"2018-12-11T12:04:12Z","doi":"10.1086/587062","author":[{"last_name":"De Cara","full_name":"De Cara, Maria A","first_name":"Maria"},{"first_name":"Nicholas H","orcid":"0000-0002-8548-5240","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","last_name":"Barton","full_name":"Nicholas Barton"},{"first_name":"Mark","last_name":"Kirkpatrick","full_name":"Kirkpatrick, Mark"}],"year":"2008","issue":"5","date_published":"2008-05-01T00:00:00Z","date_updated":"2021-01-12T07:44:36Z","citation":{"chicago":"De Cara, Maria, Nicholas H Barton, and Mark Kirkpatrick. “A Model for the Evolution of Assortative Mating.” <i>American Naturalist</i>.

The formulae are derived using a continuous diffusion approximation, which is accurate over all but very small spatial scales. The continuous approximation is confirmed by comparison with the exact solution to the stepping stone model. In both one and two spatial dimensions, the variance of fluctuations in allele frequencies increases near the barrier; when the barrier is very strong, the variance doubles. However, the effect on fluctuations close to the barrier is much greater when the population is spread over two spatial dimensions than when it occupies a linear, one-dimensional habitat: barriers of strength comparable with the dispersal range (B≈σ) can have an appreciable effect in two dimensions, whereas only barriers with strength comparable with the characteristic scale (B\\! \\approx\\! L \\equals \\sigma \\sol \\sqrt {2 \\mu}\\hskip2) are significant in one dimension (μ is the rate of mutation or long-range dispersal). Thus, in a two-dimensional population, barriers to gene flow can be detected through their effect on the spatial pattern of genetic marker alleles.","lang":"eng"}],"publication_status":"published","intvolume":"        90","doi":"10.1017/S0016672307009081","type":"journal_article","quality_controlled":0}]
