  text: A comparative, experimental diffusivity study of gas diffusion layer (GDL)
    materials for polymer electrolyte fuel cells (PEFC) is presented for the first
    time. The GDL plays an important role for electrochemical losses due to gas transport
    limitations at high current densities. Characterization and optimization of these
    layers is therefore essential to improve power density. A recently developed method
    which allows for fast diffusimetry is applied and data compared to the literature
    values. Measurements are made as a function of direction and compression and the
    effect of different binder structures and hydrophobic treatments on effective
    diffusivities are discussed. A better understanding of the results is gained by
    including novel GDL cross-section images and a meaningful unit cell model for
    the interpretation of the data. The diffusivity data is valuable for GDL manufacturers
    and future PEFC models. The study reveals that a binder–fiber ratio larger than
    50% has a negative impact on the effective diffusion properties. The hydrophobic
    treatment which is necessary to improve the water management can impede diffusion
    and thus reduce the power density. Furthermore binder has an isotropic effect
    while compression pronounces the in-plane orientation of the fibers.

  text: Cell interaction phenomena in polymer electrolyte fuel cell stacks that arise
    from imbalance between adjacent cells are investigated in detail experimentally
    and theoretically. 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.

  text: The gas diffusion layers (GDLs) of a membrane electrode assembly (MEA) serve
    as link between flow field and porous electrode within a polymer electrolyte fuel
    cell. 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.

  text: The propagation of single cell performance losses to adjacent cells in a polymer
    electrolyte fuel cell stack is studied by means of local current density measurements
    in a two cell stack. In this stack, the working conditions of adjacent cells can
    be controlled independently in order to deliberately change the performance of
    one cell (inducing cell) and study the coupling effects to the adjacent cell (response
    cell), while keeping the working conditions of the later one unchanged. The experiments
    have shown that changes in the current density distribution caused by lowering
    of the air stoichiometry in the inducing cell cause changes in the current density
    distribution of the response cell in the order of 60% of the change of the inducing
    cell, even when the air stoichiometry of the response cell is kept constant. The
    losses in cell voltage of the inducing cell cause losses in cell voltage of the
    response cell in a magnitude between 30 and 50%.

  text: 'This paper addresses the following question: what is the minimum-sized synchronous
    window needed to solve consensus in an otherwise asynchronous system? In answer
    to this question, we present the first optimally-resilient algorithm ASAP that
    solves consensus as soon as possible in an eventually synchronous system, i.e.,
    a system that from some time GST onwards, delivers messages in a timely fashion.
    ASAP guarantees that, in an execution with at most f failures, every process decides
    no later than round GST + f + 2, which is optimal.'

  text: We develop a new method for estimating effective population sizes, Ne, and
    selection coefficients, s, from time-series data of allele frequencies sampled
    from a single diallelic locus. The method is based on calculating transition probabilities,
    using a numerical solution of the diffusion process, and assuming independent
    binomial sampling from this diffusion process at each time point. We apply the
    method in two example applications. First, we estimate selection coefficients
    acting on the CCR5-Δ32 mutation on the basis of published samples of contemporary
    and ancient human DNA. 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. In our second example, we estimate the selection coefficient acting
    on a mutation segregating in an experimental phage population. We show that the
    selection coefficient acting on this mutation is ~0.43.

    The Wikipedia is a collaborative encyclopedia: anyone can contribute to its articles simply by clicking on an &quot;edit&quot; button. 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.

    The 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.

    We 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.

  text: 'In content-driven reputation systems for collaborative content, users gain
    or lose reputation according to how their contributions fare: authors of long-lived
    contributions gain reputation, while authors of reverted contributions lose reputation.
    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. Copyright 2008 ACM.'

  text: "Simulation and bisimulation metrics for stochastic systems provide a quantitative
    gen- eralization of the classical simulation and bisimulation relations. 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. These
    algorithms can be iterated\r\nto approximate the metrics using binary search."

    to the rate, at which neurons fire. Evidence of temporal coding in the hippocampus
    comes from place cells, whose spike times relative to theta oscillations reflect
    a rat's position while running along stereotyped trajectories. 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 represents the first direct evidence of a combined representation
    of position, trajectory and heading in the hippocampus, organized on a fine temporal
    scale by theta oscillations.

  text: The hippocampus is thought to be involved in episodic memory formation by
    reactivating traces of waking experience during sleep. Indeed, the joint firing
    of spatially tuned pyramidal cells encoding nearby places recur during sleep.
    We found that the sleep cofiring of rat CA1 pyramidal cells encoding similar places
    increased relative to the sleep session before exploration. 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. In contrast, cells encoding different locations reduced
    their cofiring in proportion to the number of times that they fired independently.
    Together these data indicate that reactivated patterns are shaped by both positive
    and negative changes in cofiring, which are determined by recent behavior.

  text: In the cerebral cortex, GABAergic interneurons are often regarded as fast-spiking
    cells. We have identified a type of slow-spiking interneuron that offers distinct
    contributions to network activity. “Ivy” cells, named after their dense and fine
    axons innervating mostly basal and oblique pyramidal cell dendrites, are more
    numerous than the parvalbumin-expressing basket, bistratified, or axo-axonic cells.
    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. In contrast to fast-spiking
    interneurons operating with millisecond precision, the highly abundant Ivy cells
    express presynaptically acting neuromodulators and regulate the excitability of
    pyramidal cell dendrites through slowly rising and decaying GABAergic inputs.

  text: 'Hippocampal place cells that fire together within the same cycle of theta
    oscillations represent the sequence of positions (movement trajectory) that a
    rat traverses on a linear track. 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.'

  text: In the subthalamic nucleus (STN) of Parkinson's disease (PD) patients, a pronounced
    synchronization of oscillatory activity at beta frequencies (15-30 Hz) accompanies
    movement difficulties. 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.

  text: The controlled internalization of membrane receptors and lipids is crucial
    for cells to control signaling pathways and interact with their environment. During
    clathrin-mediated endocytosis, membrane constituents are transported via endocytic
    vesicles into early endosomes, from which they are further distributed within
    the cell. The small guanosine triphosphatase (GTPase) Rab5 is both required and
    sufficient for the formation of these early endosomes and can be used to experimentally
    address endocytic processes. 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. This in turn
    leads to effective and synchronized movement within the embryo. In this review,
    we discuss techniques to manipulate E-cadherin endocytosis by morpholino-mediated
    knockdown of rab5 during zebrafish gastrulation. We describe the use of antibodies
    specifically directed against zebrafish E-cadherin to detect its intracellular
    localization and of in situ hybridization and primary cell culture to reveal patterns
    of cell migration and adhesion, respectively

  text: In this paper, adaptive formation control and bio-inspired optimization are
    jointly addressed for a cluster-based satellite wireless sensor network in which
    there are multiple satellites flying in formation (MSFF) in the presence of unknown
    disturbances. The full nonlinear dynamics model describing the relative positioning
    of the MSFF system is used to develop an adaptive formation controller. First,
    the original nonlinear system is transformed into a linear controllable system
    with aperturbation term by invoking the input-output feedback linearization technique.
    Second, by using the integral feedback design scheme, the adaptive formation controller
    is presented for improving the steady-state performance of the MSFF system in
    the presence of unknown disturbances. Third, as a currently popular bio-inspired
    algorithm, PSO (particle swarm optimizer) is employed to minimize the total energy
    consumption under the required quality of service by jointly optimizing the transmission
    power and rate for each satellite. Simulation results are provided to demonstrate
    the effectiveness of the adaptive formation controller and the PSO-based optimization
    for saving the total communication energy.

  text: Scalability is one of the most important issues for optimization algorithms
    used in wireless sensor networks (WSNs) since there are often many parameters
    to be optimized at the same time. 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.
