  text: We present a new decidable logic called TREX for expressing constraints about
    imperative tree data structures. In particular, TREX supports a transitive closure
    operator that can express reachability constraints, which often appear in data
    structure invariants. We show that our logic is closed under weakest precondition
    computation, which enables its use for automated software verification. We further
    show that satisfiability of formulas in TREX is decidable in NP. The low complexity
    makes it an attractive alternative to more expensive logics such as monadic second-order
    logic (MSOL) over trees, which have been traditionally used for reasoning about
    tree data structures.

  text: 'We consider probabilistic automata on infinite words with acceptance defined
    by parity conditions. We consider three qualitative decision problems: (i) the
    positive decision problem asks whether there is a word that is accepted with positive
    probability; (ii) the almost decision problem asks whether there is a word that
    is accepted with probability 1; and (iii) the limit decision problem asks whether
    for every ε > 0 there is a word that is accepted with probability at least 1 −
    ε. We unify and generalize several decidability results for probabilistic automata
    over infinite words, and identify a robust (closed under union and intersection)
    subclass of probabilistic automata for which all the qualitative decision problems
    are decidable for parity conditions. We also show that if the input words are
    restricted to lasso shape words, then the positive and almost problems are decidable
    for all probabilistic automata with parity conditions.'

  text: There is recently a significant effort to add quantitative objectives to formal
    verification and synthesis. We introduce and investigate the extension of temporal
    logics with quantitative atomic assertions, aiming for a general and flexible
    framework for quantitative-oriented specifications. In the heart of quantitative
    objectives lies the accumulation of values along a computation. It is either the
    accumulated summation, as with the energy objectives, or the accumulated average,
    as with the mean-payoff objectives. We investigate the extension of temporal logics
    with the prefix-accumulation assertions Sum(v) ≥ c and Avg(v) ≥ c, where v is
    a numeric variable of the system, c is a constant rational number, and Sum(v)
    and Avg(v) denote the accumulated sum and average of the values of v from the
    beginning of the computation up to the current point of time. We also allow the
    path-accumulation assertions LimInfAvg(v) ≥ c and LimSupAvg(v) ≥ c, referring
    to the average value along an entire computation. We study the border of decidability
    for extensions of various temporal logics. In particular, we show that extending
    the fragment of CTL that has only the EX, EF, AX, and AG temporal modalities by
    prefix-accumulation assertions and extending LTL with path-accumulation assertions,
    result in temporal logics whose model-checking problem is decidable. The extended
    logics allow to significantly extend the currently known energy and mean-payoff
    objectives. Moreover, the prefix-accumulation assertions may be refined with “controlled-accumulation”,
    allowing, for example, to specify constraints on the average waiting time between
    a request and a grant. On the negative side, we show that the fragment we point
    to is, in a sense, the maximal logic whose extension with prefix-accumulation
    assertions permits a decidable model-checking procedure. Extending a temporal
    logic that has the EG or EU modalities, and in particular CTL and LTL, makes the
    problem undecidable.

  text: 'We introduce TopoCut: a new way to integrate knowledge about topological
    properties (TPs) into random field image segmentation model. Instead of including
    TPs as additional constraints during minimization of the energy function, we devise
    an efficient algorithm for modifying the unary potentials such that the resulting
    segmentation is guaranteed with the desired properties. Our method is more flexible
    in the sense that it handles more topology constraints than previous methods,
    which were only able to enforce pairwise or global connectivity. In particular,
    our method is very fast, making it for the first time possible to enforce global
    topological properties in practical image segmentation tasks.'

  text: We consider Markov Decision Processes (MDPs) with mean-payoff parity and energy
    parity objectives. In system design, the parity objective is used to encode ω-regular
    specifications, and the mean-payoff and energy objectives can be used to model
    quantitative resource constraints. The energy condition re- quires that the resource
    level never drops below 0, and the mean-payoff condi- tion requires that the limit-average
    value of the resource consumption is within a threshold. While these two (energy
    and mean-payoff) classical conditions are equivalent for two-player games, we
    show that they differ for MDPs. We show that the problem of deciding whether a
    state is almost-sure winning (i.e., winning with probability 1) in energy parity
    MDPs is in NP ∩ coNP, while for mean- payoff parity MDPs, the problem is solvable
    in polynomial time, improving a recent PSPACE bound.

  text: We report the switching behavior of the full bacterial flagellum system that
    includes the filament and the motor in wild-type Escherichia coli cells. In sorting
    the motor behavior by the clockwise bias, we find that the distributions of the
    clockwise (CW) and counterclockwise (CCW) intervals are either exponential or
    nonexponential with long tails. At low bias, CW intervals are exponentially distributed
    and CCW intervals exhibit long tails. At intermediate CW bias (0.5) both CW and
    CCW intervals are mainly exponentially distributed. A simple model suggests that
    these two distinct switching behaviors are governed by the presence of signaling
    noise within the chemotaxis network. Low noise yields exponentially distributed
    intervals, whereas large noise yields nonexponential behavior with long tails.
    These drastically different motor statistics may play a role in optimizing bacterial
    behavior for a wide range of environmental conditions.

  text: Imprinted genes are expressed primarily or exclusively from either the maternal
    or paternal allele, a phenomenon that occurs in flowering plants and mammals.
    Flowering plant imprinted gene expression has been described primarily in endosperm,
    a terminal nutritive tissue consumed by the embryo during seed development or
    after germination. Imprinted expression in Arabidopsis thaliana endosperm is orchestrated
    by differences in cytosine DNA methylation between the paternal and maternal genomes
    as well as by Polycomb group proteins. Currently, only 11 imprinted A. thaliana
    genes are known. Here, we use extensive sequencing of cDNA libraries to identify
    9 paternally expressed and 34 maternally expressed imprinted genes in A. thaliana
    endosperm that are regulated by the DNA-demethylating glycosylase DEMETER, the
    DNA methyltransferase MET1, and/or the core Polycomb group protein FIE. These
    genes encode transcription factors, proteins involved in hormone signaling, components
    of the ubiquitin protein degradation pathway, regulators of histone and DNA methylation,
    and small RNA pathway proteins. We also identify maternally expressed genes that
    may be regulated by unknown mechanisms or deposited from maternal tissues. We
    did not detect any imprinted genes in the embryo. Our results show that imprinted
    gene expression is an extensive mechanistically complex phenomenon that likely
    affects multiple aspects of seed development.

  text: In this paper, we establish a correspondence between the incremental algorithm
    for computing AT-models [8,9] and the one for computing persistent homology [6,14,15].
    We also present a decremental algorithm for computing AT-models that allows to
    extend the persistence computation to a wider setting. Finally, we show how to
    combine incremental and decremental techniques for persistent homology computation.

  text: Defining population structure and genetic diversity levels is of the utmost
    importance for developing efficient conservation strategies. Overfishing has caused
    mean annual catches of the European spiny lobster (Palinurus elephas) to decrease
    alarmingly along its distribution area. In this context, there is a need for comprehensive
    studies to evaluate the genetic health of the exploited populations. The present
    work is based on a set of 10 nuclear markers amplified in 331 individuals from
    10 different localities covering most of P. elephas distribution area. Samples
    from Atlantic and Mediterranean basins showed small but significant differences,
    indicating that P. elephas populations do not behave as a single panmictic unit
    but form two partially-overlapping groups. Despite intense overfishing, our dataset
    did not recover a recent bottleneck signal, and showed a large and stable historical
    effective size instead. This result could be accounted for by specific life history
    traits (reproduction and longevity) and the limitations of molecular markers in
    covering very recent timescales for non temporal samples. Our study emphasizes
    the necessity of integrating information on effective population sizes and life
    history parameters when evaluating population connectivity levels from genetic
    data.

  text: We consider Markov Decision Processes (MDPs) with mean-payoff parity and energy
    parity objectives. In system design, the parity objective is used to encode ω-regular
    specifications, and the mean-payoff and energy objectives can be used to model
    quantitative resource constraints. The energy condition re- quires that the resource
    level never drops below 0, and the mean-payoff condi- tion requires that the limit-average
    value of the resource consumption is within a threshold. While these two (energy
    and mean-payoff) classical conditions are equivalent for two-player games, we
    show that they differ for MDPs. We show that the problem of deciding whether a
    state is almost-sure winning (i.e., winning with probability 1) in energy parity
    MDPs is in NP ∩ coNP, while for mean- payoff parity MDPs, the problem is solvable
    in polynomial time, improving a recent PSPACE bound.

  text: We study Markov decision processes (MDPs) with multiple limit-average (or
    mean-payoff) functions. We consider two different objectives, namely, expectation
    and satisfaction objectives. Given an MDP with k reward functions, in the expectation
    objective the goal is to maximize the expected limit-average value, and in the
    satisfaction objective the goal is to maximize the probability of runs such that
    the limit-average value stays above a given vector. We show that under the expectation
    objective, in contrast to the single-objective case, both randomization and memory
    are necessary for strategies, and that finite-memory randomized strategies are
    sufficient. Under the satisfaction objective, in contrast to the single-objective
    case, infinite memory is necessary for strategies, and that randomized memoryless
    strategies are sufficient for epsilon-approximation, for all epsilon&gt;;0. We
    further prove that the decision problems for both expectation and satisfaction
    objectives can be solved in polynomial time and the trade-off curve (Pareto curve)
    can be epsilon-approximated in time polynomial in the size of the MDP and 1/epsilon,
    and exponential in the number of reward functions, for all epsilon&gt;;0. Our
    results also reveal flaws in previous work for MDPs with multiple mean-payoff
    functions under the expectation objective, correct the flaws and obtain improved
    results.

  text: 'The class of omega-regular languages provides a robust specification language
    in verification. Every omega-regular condition can be decomposed into a safety
    part and a liveness part. The liveness part ensures that something good happens
    &quot;eventually&quot;. Finitary liveness was proposed by Alur and Henzinger as
    a stronger formulation of liveness. It requires that there exists an unknown,
    fixed bound b such that something good happens within b transitions. In this work
    we consider automata with finitary acceptance conditions defined by finitary Buchi,
    parity and Streett languages. We study languages expressible by such automata:
    we give their topological complexity and present a regular-expression characterization.
    We compare the expressive power of finitary automata and give optimal algorithms
    for classical decisions questions. We show that the finitary languages are Sigma
    2-complete; we present a complete picture of the expressive power of various classes
    of automata with finitary and infinitary acceptance conditions; we show that the
    languages defined by finitary parity automata exactly characterize the star-free
    fragment of omega B-regular languages; and we show that emptiness is NLOGSPACE-complete
    and universality as well as language inclusion are PSPACE-complete for finitary
    parity and Streett automata.'

  text: We study synthesis of controllers for real-time systems, where the objective
    is to stay in a given safe set. The problem is solved by obtaining winning strategies
    in the setting of concurrent two-player timed automaton games with safety objectives.
    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. We construct winning strategies for the controller which require access only
    to (1) the system clocks (thus, controllers which require their own internal infinitely
    precise clocks are not necessary), and (2) a linear (in the number of clocks)
    number of memory bits. Precisely, we show that for safety objectives, a memory
    of size (3 · |C|+lg(|C|+1)) bits suffices for winning controller strategies, where
    C is the set of clocks of the timed automaton game, significantly improving the
    previous known exponential bound. We also settle the open question of whether
    winning region controller strategies require memory for safety objectives by showing
    with an example the necessity of memory for region strategies to win for safety
    objectives.

  text: 'Games on graphs provide a natural model for reactive non-terminating systems.
    In such games, the interaction of two players on an arena results in an infinite
    path that describes a run of the system. Different settings are used to model
    various open systems in computer science, as for instance turn-based or concurrent
    moves, and deterministic or stochastic transitions. In this paper, we are interested
    in turn-based games, and specifically in deterministic parity games and stochastic
    reachability games (also known as simple stochastic games). We present a simple,
    direct and efficient reduction from deterministic parity games to simple stochastic
    games: it yields an arena whose size is linear up to a logarithmic factor in size
    of the original arena.'

  text: A controller for a discrete game with ω-regular objectives requires attention
    if, intuitively, it requires measuring the state and switching from the current
    control action. Minimum attention controllers are preferable in modern shared
    implementations of cyber-physical systems because they produce the least burden
    on system resources such as processor time or communication bandwidth. We give
    algorithms to compute minimum attention controllers for ω-regular objectives in
    imperfect information discrete two-player games. We show a polynomial-time reduction
    from minimum attention controller synthesis to synthesis of controllers for mean-payoff
    parity objectives in games of incomplete information. This gives an optimal EXPTIME-complete
    synthesis algorithm. We show that the minimum attention controller problem is
    decidable for infinite state systems with finite bisimulation quotients. In particular,
    the problem is decidable for timed and rectangular automata.

  text: In two-player games on graph, the players construct an infinite path through
    the game graph and get a reward computed by a payoff function over infinite paths.
    Over weighted graphs, the typical and most studied payoff functions compute the
    limit-average or the discounted sum of the rewards along the path. Besides their
    simple definition, these two payoff functions enjoy the property that memoryless
    optimal strategies always exist. In an attempt to construct other simple payoff
    functions, we define a class of payoff functions which compute an (infinite) weighted
    average of the rewards. This new class contains both the limit-average and the
    discounted sum functions, and we show that they are the only members of this class
    which induce memoryless optimal strategies, showing that there is essentially
    no other simple payoff functions.

  text: 'Compositional theories are crucial when designing large and complex systems
    from smaller components. In this work we propose such a theory for synchronous
    concurrent systems. Our approach follows so-called interface theories, which use
    game-theoretic interpretations of composition and refinement. These are appropriate
    for systems with distinct inputs and outputs, and explicit conditions on inputs
    that must be enforced during composition. Our interfaces model systems that execute
    in an infinite sequence of synchronous rounds. At each round, a contract must
    be satisfied. The contract is simply a relation specifying the set of valid input/output
    pairs. Interfaces can be composed by parallel, serial or feedback composition.
    A refinement relation between interfaces is defined, and shown to have two main
    properties: (1) it is preserved by composition, and (2) it is equivalent to substitutability,
    namely, the ability to replace an interface by another one in any context. Shared
    refinement and abstraction operators, corresponding to greatest lower and least
    upper bounds with respect to refinement, are also defined. Input-complete interfaces,
    that impose no restrictions on inputs, and deterministic interfaces, that produce
    a unique output for any legal input, are discussed as special cases, and an interesting
    duality between the two classes is exposed. A number of illustrative examples
    are provided, as well as algorithms to compute compositions, check refinement,
    and so on, for finite-state interfaces.'

  text: 'We consider two-player games played on a finite state space for an infinite
    number of rounds. The games are concurrent: in each round, the two players (player
    1 and player 2) choose their moves independently and simultaneously; the current
    state and the two moves determine the successor state. We consider ω-regular winning
    conditions specified as parity objectives. Both players are allowed to use randomization
    when choosing their moves. We study the computation of the limit-winning set of
    states, consisting of the states where the sup-inf value of the game for player
    1 is 1: in other words, a state is limit-winning if player 1 can ensure a probability
    of winning arbitrarily close to 1. We show that the limit-winning set can be computed
    in O(n2d+2) time, where n is the size of the game structure and 2d is the number
    of priorities (or colors). The membership problem of whether a state belongs to
    the limit-winning set can be decided in NP ∩ coNP. While this complexity is the
    same as for the simpler class of turn-based parity games, where in each state
    only one of the two players has a choice of moves, our algorithms are considerably
    more involved than those for turn-based games. This is because concurrent games
    do not satisfy two of the most fundamental properties of turn-based parity games.
    First, in concurrent games limit-winning strategies require randomization; and
    second, they require infinite memory.'
