  text: The plant hormones auxin and cytokinin mutually coordinate their activities
    to control various aspects of development [1-9], and their crosstalk occurs at
    multiple levels [10, 11]. Cytokinin-mediated modulation of auxin transport provides
    an efficient means to regulate auxin distribution in plant organs. Here, we demonstrate
    that cytokinin does not merely control the overall auxin flow capacity, but might
    also act as a polarizing cue and control the auxin stream directionality during
    plant organogenesis. Cytokinin enhances the PIN-FORMED1 (PIN1) auxin transporter
    depletion at specific polar domains, thus rearranging the cellular PIN polarities
    and directly regulating the auxin flow direction. This selective cytokinin sensitivity
    correlates with the PIN protein phosphorylation degree. PIN1 phosphomimicking
    mutations, as well as enhanced phosphorylation in plants with modulated activities
    of PIN-specific kinases and phosphatases, desensitize PIN1 to cytokinin. Our results
    reveal conceptually novel, cytokinin-driven polarization mechanism that operates
    in developmental processes involving rapid auxin stream redirection, such as lateral
    root organogenesis, in which a gradual PIN polarity switch defines the growth
    axis of the newly formed organ.

  text: 'We consider Ising models in d = 2 and d = 3 dimensions with nearest neighbor
    ferromagnetic and long-range antiferromagnetic interactions, the latter decaying
    as (distance)-p, p &gt; 2d, at large distances. If the strength J of the ferromagnetic
    interaction is larger than a critical value J c, then the ground state is homogeneous.
    It has been conjectured that when J is smaller than but close to J c, the ground
    state is periodic and striped, with stripes of constant width h = h(J), and h
    → ∞ as J → Jc -. (In d = 3 stripes mean slabs, not columns.) Here we rigorously
    prove that, if we normalize the energy in such a way that the energy of the homogeneous
    state is zero, then the ratio e 0(J)/e S(J) tends to 1 as J → Jc -, with e S(J)
    being the energy per site of the optimal periodic striped/slabbed state and e
    0(J) the actual ground state energy per site of the system. Our proof comes with
    explicit bounds on the difference e 0(J)-e S(J) at small but positive J c-J, and
    also shows that in this parameter range the ground state is striped/slabbed in
    a certain sense: namely, if one looks at a randomly chosen window, of suitable
    size ℓ (very large compared to the optimal stripe size h(J)), one finds a striped/slabbed
    state with high probability.'

  text: 'The social intelligence hypothesis states that the need to cope with complexities
    of social life has driven the evolution of advanced cognitive abilities. It is
    usually invoked in the context of challenges arising from complex intragroup structures,
    hierarchies, and alliances. However, a fundamental aspect of group living remains
    largely unexplored as a driving force in cognitive evolution: the competition
    between individuals searching for resources (producers) and conspecifics that
    parasitize their findings (scroungers). In populations of social foragers, abilities
    that enable scroungers to steal by outsmarting producers, and those allowing producers
    to prevent theft by outsmarting scroungers, are likely to be beneficial and may
    fuel a cognitive arms race. Using analytical theory and agent-based simulations,
    we present a general model for such a race that is driven by the producer-scrounger
    game and show that the race''s plausibility is dramatically affected by the nature
    of the evolving abilities. If scrounging and scrounging avoidance rely on separate,
    strategy-specific cognitive abilities, arms races are short-lived and have a limited
    effect on cognition. However, general cognitive abilities that facilitate both
    scrounging and scrounging avoidance undergo stable, long-lasting arms races. Thus,
    ubiquitous foraging interactions may lead to the evolution of general cognitive
    abilities in social animals, without the requirement of complex intragroup structures.'

    that the limiting spectrum is supported on a single interval, and the external
    potential is C4 and regular. We also prove that the edge universality holds for
    generalized Wigner matrices for all symmetry classes. Moreover, our results allow
    us to extend bulk universality for beta ensembles from analytic potentials to

  text: Invasive alien parasites and pathogens are a growing threat to biodiversity
    worldwide, which can contribute to the extinction of endemic species. On the Galápagos
    Islands, the invasive parasitic fly Philornis downsi poses a major threat to the
    endemic avifauna. Here, we investigated the influence of this parasite on the
    breeding success of two Darwin's finch species, the warbler finch (Certhidea olivacea)
    and the sympatric small tree finch (Camarhynchus parvulus), on Santa Cruz Island
    in 2010 and 2012. While the population of the small tree finch appeared to be
    stable, the warbler finch has experienced a dramatic decline in population size
    on Santa Cruz Island since 1997. We aimed to identify whether warbler finches
    are particularly vulnerable during different stages of the breeding cycle. Contrary
    to our prediction, breeding success was lower in the small tree finch than in
    the warbler finch. In both species P. downsi had a strong negative impact on breeding
    success and our data suggest that heavy rain events also lowered the fledging
    success. On the one hand parents might be less efficient in compensating their
    chicks' energy loss due to parasitism as they might be less efficient in foraging
    on days of heavy rain. On the other hand, intense rainfalls might lead to increased
    humidity and more rapid cooling of the nests. In the case of the warbler finch
    we found that the control of invasive plant species with herbicides had a significant
    additive negative impact on the breeding success. It is very likely that the availability
    of insects (i.e. food abundance) is lower in such controlled areas, as herbicide
    usage led to the removal of the entire understory. Predation seems to be a minor
    factor in brood loss.

  text: 'First cycle games (FCG) are played on a finite graph by two players who push
    a token along the edges until a vertex is repeated, and a simple cycle is formed.
    The winner is determined by some fixed property Y of the sequence of labels of
    the edges (or nodes) forming this cycle. These games are traditionally of interest
    because of their connection with infinite-duration games such as parity and mean-payoff
    games. We study the memory requirements for winning strategies of FCGs and certain
    associated infinite duration games. We exhibit a simple FCG that is not memoryless
    determined (this corrects a mistake in Memoryless determinacy of parity and mean
    payoff games: a simple proof by Bj⋯orklund, Sandberg, Vorobyov (2004) that claims
    that FCGs for which Y is closed under cyclic permutations are memoryless determined).
    We show that θ (n)! memory (where n is the number of nodes in the graph), which
    is always sufficient, may be necessary to win some FCGs. On the other hand, we
    identify easy to check conditions on Y (i.e., Y is closed under cyclic permutations,
    and both Y and its complement are closed under concatenation) that are sufficient
    to ensure that the corresponding FCGs and their associated infinite duration games
    are memoryless determined. We demonstrate that many games considered in the literature,
    such as mean-payoff, parity, energy, etc., satisfy these conditions. On the complexity
    side, we show (for efficiently computable Y) that while solving FCGs is in PSPACE,
    solving some families of FCGs is PSPACE-hard. '

  text: Energy games belong to a class of turn-based two-player infinite-duration
    games played on a weighted directed graph. It is one of the rare and intriguing
    combinatorial problems that lie in NP∩co-NP, but are not known to be in P. The
    existence of polynomial-time algorithms has been a major open problem for decades
    and apart from pseudopolynomial algorithms there is no algorithm that solves any
    non-trivial subclass in polynomial time. In this paper, we give several results
    based on the weight structures of the graph. First, we identify a notion of penalty
    and present a polynomial-time algorithm when the penalty is large. Our algorithm
    is the first polynomial-time algorithm on a large class of weighted graphs. It
    includes several worst-case instances on which previous algorithms, such as value
    iteration and random facet algorithms, require at least sub-exponential time.
    Our main technique is developing the first non-trivial approximation algorithm
    and showing how to convert it to an exact algorithm. Moreover, we show that in
    a practical case in verification where weights are clustered around a constant
    number of values, the energy game problem can be solved in polynomial time. We
    also show that the problem is still as hard as in general when the clique-width
    is bounded or the graph is strongly ergodic, suggesting that restricting the graph
    structure does not necessarily help.

  text: Transgenerational effects are broader than only parental relationships. Despite
    mounting evidence that multigenerational effects alter phenotypic and life-history
    traits, our understanding of how they combine to determine fitness is not well
    developed because of the added complexity necessary to study them. Here, we derive
    a quantitative genetic model of adaptation to an extraordinary new environment
    by an additive genetic component, phenotypic plasticity, maternal and grandmaternal
    effects. We show how, at equilibrium, negative maternal and negative grandmaternal
    effects maximize expected population mean fitness. We define negative transgenerational
    effects as those that have a negative effect on trait expression in the subsequent
    generation, that is, they slow, or potentially reverse, the expected evolutionary
    dynamic. When maternal effects are positive, negative grandmaternal effects are
    preferred. As expected under Mendelian inheritance, the grandmaternal effects
    have a lower impact on fitness than the maternal effects, but this dual inheritance
    model predicts a more complex relationship between maternal and grandmaternal
    effects to constrain phenotypic variance and so maximize expected population mean
    fitness in the offspring.

  text: "Model-based testing is a promising technology for black-box software and
    hardware testing, in which test cases are generated automatically from high-level
    specifications. Nowadays, systems typically consist of multiple interacting components
    and, due to their complexity, testing presents a considerable portion of the effort
    and cost in the design process. Exploiting the compositional structure of system
    specifications can considerably reduce the effort in model-based testing. Moreover,
    inferring properties about the system from testing its individual components allows
    the designer to reduce the amount of integration testing.\r\nIn this paper, we
    study compositional properties of the IOCO-testing theory. We propose a new approach
    to composition and hiding operations, inspired by contract-based design and interface
    theories. These operations preserve behaviors that are compatible under composition
    and hiding, and prune away incompatible ones. The resulting specification characterizes
    the input sequences for which the unit testing of components is sufficient to
    infer the correctness of component integration without the need for further tests.
    We provide a methodology that uses these results to minimize integration testing
    effort, but also to detect potential weaknesses in specifications. While we focus
    on asynchronous models and the IOCO conformance relation, the resulting methodology
    can be applied to a broader class of systems."

  text: 'Recently there has been a significant effort to add quantitative properties
    in formal verification and synthesis. While weighted automata over finite and
    infinite words provide a natural and flexible framework to express quantitative
    properties, perhaps surprisingly, several basic system properties such as average
    response time cannot be expressed with weighted automata. In this work, we introduce
    nested weighted automata as a new formalism for expressing important quantitative
    properties such as average response time. We establish an almost complete decidability
    picture for the basic decision problems for nested weighted automata, and illustrate
    its applicability in several domains.  '

  text: As hybrid systems involve continuous behaviors, they should be evaluated by
    quantitative methods, rather than qualitative methods. In this paper we adapt
    a quantitative framework, called model measuring, to the hybrid systems domain.
    The model-measuring problem asks, given a model M and a specification, what is
    the maximal distance such that all models within that distance from M satisfy
    (or violate) the specification. A distance function on models is given as part
    of the input of the problem. Distances, especially related to continuous behaviors
    are more natural in the hybrid case than the discrete case. We are interested
    in distances represented by monotonic hybrid automata, a hybrid counterpart of
    (discrete) weighted automata, whose recognized timed languages are monotone (w.r.t.
    inclusion) in the values of parameters.The contributions of this paper are twofold.
    First, we give sufficient conditions under which the model-measuring problem can
    be solved. Second, we discuss the modeling of distances and applications of the
    model-measuring problem.

  text: "We define the model-measuring problem: given a model M and specification
    φ, what is the maximal distance ρ such that all models M'within distance ρ from
    M satisfy (or violate)φ. The model measuring problem presupposes a distance function
    on models. We concentrate on automatic distance functions, which are defined by
    weighted automata.\r\nThe model-measuring problem subsumes several generalizations
    of the classical model-checking problem, in particular, quantitative model-checking
    problems that measure the degree of satisfaction of a specification, and robustness
    problems that measure how much a model can be perturbed without violating the
    specification.\r\nWe show that for automatic distance functions, and ω-regular
    linear-time and branching-time specifications, the model-measuring problem can
    be solved.\r\nWe use automata-theoretic model-checking methods for model measuring,
    replacing the emptiness question for standard word and tree automata by the optimal-weight
    question for the weighted versions of these automata. We consider weighted automata
    that accumulate weights by maximizing, summing, discounting, and limit averaging.
    \r\nWe give several examples of using the model-measuring problem to compute various
    notions of robustness and quantitative satisfaction for temporal specifications."

  text: We consider multi-player graph games with partial-observation and parity objective.
    While the decision problem for three-player games with a coalition of the first
    and second players against the third player is undecidable, we present a decidability
    result for partial-observation games where the first and third player are in a
    coalition against the second player, thus where the second player is adversarial
    but weaker due to partial-observation. We establish tight complexity bounds in
    the case where player 1 is less informed than player 2, namely 2-EXPTIME-completeness
    for parity objectives. The symmetric case of player 1 more informed than player
    2 is much more complicated, and we show that already in the case where player
    1 has perfect observation, memory of size non-elementary is necessary in general
    for reachability objectives, and the problem is decidable for safety and reachability
    objectives. Our results have tight connections with partial-observation stochastic
    games for which we derive new complexity results.

  text: "We consider the reachability and shortest path problems on low tree-width
    graphs, with n nodes, m edges, and tree-width t, on a standard RAM with wordsize

    Our main contributions are three fold:\r\n1. For reachability, we present an algorithm
    that requires O(n·t2·log(n/t)) preprocessing time, O(n·(t·log(n/t))/W) space,
    and O(t/W) time for pair queries and O((n·t)/W) time for single-source queries.
    Note that for constant t our algorithm uses O(n·logn) time for preprocessing;
    and O(n/W) time for single-source queries, which is faster than depth first search/breath
    first search (after the preprocessing).\r\n2. We present an algorithm for shortest
    path that requires O(n·t2) preprocessing time, O(n·t) space, and O(t2) time for
    pair queries and O(n·t) time single-source queries.\r\n3. We give a space versus

    queries.\r\nOur algorithms improve all existing results, and use very simple data

  text: 'We consider concurrent mean-payoff games, a very well-studied class of two-player
    (player 1 vs player 2) zero-sum games on finite-state graphs where every transition
    is assigned a reward between 0 and 1, and the payoff function is the long-run
    average of the rewards. The value is the maximal expected payoff that player 1
    can guarantee against all strategies of player 2. We consider the computation
    of the set of states with value 1 under finite-memory strategies for player 1,
    and our main results for the problem are as follows: (1) we present a polynomial-time
    algorithm; (2) we show that whenever there is a finite-memory strategy, there
    is a stationary strategy that does not need memory at all; and (3) we present
    an optimal bound (which is double exponential) on the patience of stationary strategies
    (where patience of a distribution is the inverse of the smallest positive probability
    and represents a complexity measure of a stationary strategy).'

  text: 'Evolution occurs in populations of reproducing individuals. The structure
    of the population affects the outcome of the evolutionary process. Evolutionary
    graph theory is a powerful approach to study this phenomenon. There are two graphs.
    The interaction graph specifies who interacts with whom in the context of evolution.
    The replacement graph specifies who competes with whom for reproduction. The vertices
    of the two graphs are the same, and each vertex corresponds to an individual.
    A key quantity is the fixation probability of a new mutant. It is defined as the
    probability that a newly introduced mutant (on a single vertex) generates a lineage
    of offspring which eventually takes over the entire population of resident individuals.
    The basic computational questions are as follows: (i) the qualitative question
    asks whether the fixation probability is positive; and (ii) the quantitative approximation
    question asks for an approximation of the fixation probability. Our main results
    are: (1) We show that the qualitative question is NP-complete and the quantitative
    approximation question is #P-hard in the special case when the interaction and
    the replacement graphs coincide and even with the restriction that the resident
    individuals do not reproduce (which corresponds to an invading population taking
    over an empty structure). (2) We show that in general the qualitative question
    is PSPACE-complete and the quantitative approximation question is PSPACE-hard
    and can be solved in exponential time.'
