  text: Watermarking techniques for vector graphics dislocate vertices in order to
    embed imperceptible, yet detectable, statistical features into the input data.
    The embedding process may result in a change of the topology of the input data,
    e.g., by introducing self-intersections, which is undesirable or even disastrous
    for many applications. In this paper we present a watermarking framework for two-dimensional
    vector graphics that employs conventional watermarking techniques but still provides
    the guarantee that the topology of the input data is preserved. The geometric
    part of this framework computes so-called maximum perturbation regions (MPR) of
    vertices. We propose two efficient algorithms to compute MPRs based on Voronoi
    diagrams and constrained triangulations. Furthermore, we present two algorithms
    to conditionally correct the watermarked data in order to increase the watermark
    embedding capacity and still guarantee topological correctness. While we focus
    on the watermarking of input formed by straight-line segments, one of our approaches
    can also be extended to circular arcs. We conclude the paper by demonstrating
    and analyzing the applicability of our framework in conjunction with two well-known
    watermarking techniques.

  text: Hitting and batting tasks, such as tennis forehands, ping-pong strokes, or
    baseball batting, depend on predictions where the ball can be intercepted and
    how it can properly be returned to the opponent. These predictions get more accurate
    over time, hence the behaviors need to be continuously modified. As a result,
    movement templates with a learned global shape need to be adapted during the execution
    so that the racket reaches a target position and velocity that will return the
    ball over to the other side of the net or court. It requires altering learned
    movements to hit a varying target with the necessary velocity at a specific instant
    in time. Such a task cannot be incorporated straightforwardly in most movement
    representations suitable for learning. For example, the standard formulation of
    the dynamical system based motor primitives (introduced by Ijspeert et al (2002b))
    does not satisfy this property despite their flexibility which has allowed learning
    tasks ranging from locomotion to kendama. In order to fulfill this requirement,
    we reformulate the Ijspeert framework to incorporate the possibility of specifying
    a desired hitting point and a desired hitting velocity while maintaining all advantages
    of the original formulation.We show that the proposed movement template formulation
    works well in two scenarios, i.e., for hitting a ball on a string with a table
    tennis racket at a specified velocity and for returning balls launched by a ball
    gun successfully over the net using forehand movements.

  text: We prove polynomial upper bounds of geometric Ramsey numbers of pathwidth-2
    outerplanar triangulations in both convex and general cases. We also prove that
    the geometric Ramsey numbers of the ladder graph on 2n vertices are bounded by
    O(n3) and O(n10), in the convex and general case, respectively. We then apply
    similar methods to prove an (Formula presented.) upper bound on the Ramsey number

  text: 'Local protein interactions (&quot;molecular context&quot; effects) dictate
    amino acid replacements and can be described in terms of site-specific, energetic
    preferences for any different amino acid. It has been recently debated whether
    these preferences remain approximately constant during evolution or whether, due
    to coevolution of sites, they change strongly. Such research highlights an unresolved
    and fundamental issue with far-reaching implications for phylogenetic analysis
    and molecular evolution modeling. Here, we take advantage of the recent availability
    of phenotypically supported laboratory resurrections of Precambrian thioredoxins
    and β-lactamases to experimentally address the change of site-specific amino acid
    preferences over long geological timescales. Extensive mutational analyses support
    the notion that evolutionary adjustment to a new amino acid may occur, but to
    a large extent this is insufficient to erase the primitive preference for amino
    acid replacements. Generally, site-specific amino acid preferences appear to remain
    conserved throughout evolutionary history despite local sequence divergence. We
    show such preference conservation to be readily understandable in molecular terms
    and we provide crystallographic evidence for an intriguing structural-switch mechanism:
    Energetic preference for an ancestral amino acid in a modern protein can be linked
    to reorganization upon mutation to the ancestral local structure around the mutated
    site. Finally, we point out that site-specific preference conservation naturally
    leads to one plausible evolutionary explanation for the existence of intragenic
    global suppressor mutations.'

  text: We prove a Strichartz inequality for a system of orthonormal functions, with
    an optimal behavior of the constant in the limit of a large number of functions.
    The estimate generalizes the usual Strichartz inequality, in the same fashion
    as the Lieb-Thirring inequality generalizes the Sobolev inequality. As an application,
    we consider the Schrödinger equation with a time-dependent potential and we show
    the existence of the wave operator in Schatten spaces.

  text: ' A discounted-sum automaton (NDA) is a nondeterministic finite automaton
    with edge weights, valuing a run by the discounted sum of visited edge weights.
    More precisely, the weight in the i-th position of the run is divided by λi, where
    the discount factor λ is a fixed rational number greater than 1. The value of
    a word is the minimal value of the automaton runs on it. Discounted summation
    is a common and useful measuring scheme, especially for infinite sequences, reflecting
    the assumption that earlier weights are more important than later weights. Unfortunately,
    determinization of NDAs, which is often essential in formal verification, is,
    in general, not possible. We provide positive news, showing that every NDA with
    an integral discount factor is determinizable. We complete the picture by proving
    that the integers characterize exactly the discount factors that guarantee determinizability:
    for every nonintegral rational discount factor λ, there is a nondeterminizable
    λ-NDA. We also prove that the class of NDAs with integral discount factors enjoys
    closure under the algebraic operations min, max, addition, and subtraction, which
    is not the case for general NDAs nor for deterministic NDAs. For general NDAs,
    we look into approximate determinization, which is always possible as the influence
    of a word''s suffix decays. We show that the naive approach, of unfolding the
    automaton computations up to a sufficient level, is doubly exponential in the
    discount factor. We provide an alternative construction for approximate determinization,
    which is singly exponential in the discount factor, in the precision, and in the
    number of states. We also prove matching lower bounds, showing that the exponential
    dependency on each of these three parameters cannot be avoided. All our results
    hold equally for automata over finite words and for automata over infinite words. '

  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 κ limit-average 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 case of one limit-average function,
    both randomization and memory are necessary for strategies even for ε-approximation,
    and that finite-memory randomized strategies are sufficient for achieving Pareto
    optimal values. Under the satisfaction objective, in contrast to the case of one
    limit-average function, infinite memory is necessary for strategies achieving
    a specific value (i.e. randomized finite-memory strategies are not sufficient),
    whereas memoryless randomized strategies are sufficient for ε-approximation, for
    all ε &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 ε-approximated in time polynomial in the size of the
    MDP and 1/ε, and exponential in the number of limit-average functions, for all
    ε &gt; 0. Our analysis also reveals flaws in previous work for MDPs with multiple
    mean-payoff functions under the expectation objective, corrects the flaws, and
    allows us to obtain improved results.

  text: Coordinated migration of newly-born neurons to their target territories is
    essential for correct neuronal circuit assembly in the developing brain. Although
    a cohort of signaling pathways has been implicated in the regulation of cortical
    projection neuron migration, the precise molecular mechanisms and how a balanced
    interplay of cell-autonomous and non-autonomous functions of candidate signaling
    molecules controls the discrete steps in the migration process, are just being
    revealed. In this chapter, I will focally review recent advances that improved
    our understanding of the cell-autonomous and possible cell-nonautonomous functions
    of the evolutionarily conserved LIS1/NDEL1-complex in regulating the sequential
    steps of cortical projection neuron migration. I will then elaborate on the emerging
    concept that the Reelin signaling pathway, acts exactly at precise stages in the
    course of cortical projection neuron migration. Lastly, I will discuss how finely
    tuned transcriptional programs and downstream effectors govern particular aspects
    in driving radial migration at discrete stages and how they regulate the precise
    positioning of cortical projection neurons in the developing cerebral cortex.

  text: We present a general framework for applying machine-learning algorithms to
    the verification of Markov decision processes (MDPs). The primary goal of these
    techniques is to improve performance by avoiding an exhaustive exploration of
    the state space. Our framework focuses on probabilistic reachability, which is
    a core property for verification, and is illustrated through two distinct instantiations.
    The first assumes that full knowledge of the MDP is available, and performs a
    heuristic-driven partial exploration of the model, yielding precise lower and
    upper bounds on the required probability. The second tackles the case where we
    may only sample the MDP, and yields probabilistic guarantees, again in terms of
    both the lower and upper bounds, which provides efficient stopping criteria for
    the approximation. The latter is the first extension of statistical model checking
    for unbounded properties inMDPs. In contrast with other related techniques, our
    approach is not restricted to time-bounded (finite-horizon) or discounted properties,
    nor does it assume any particular properties of the MDP. We also show how our
    methods extend to LTL objectives. We present experimental results showing the
    performance of our framework on several examples.

  text: 'Understanding the dynamics of noisy neurons remains an important challenge
    in neuroscience. Here, we describe a simple probabilistic model that accurately
    describes the firing behavior in a large class (type II) of neurons. To demonstrate
    the usefulness of this model, we show how it accurately predicts the interspike
    interval (ISI) distributions, bursting patterns and mean firing rates found by:
    (1) simulations of the classic Hodgkin-Huxley model with channel noise, (2) experimental
    data from squid giant axon with a noisy input current and (3) experimental data
    on noisy firing from a neuron within the suprachiasmatic nucleus (SCN). This simple
    model has 6 parameters, however, in some cases, two of these parameters are coupled
    and only 5 parameters account for much of the known behavior. From these parameters,
    many properties of spiking can be found through simple calculation. Thus, we show
    how the complex effects of noise can be understood through a simple and general
    probabilistic model.'

  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: Recently, there has been an effort to add quantitative objectives to formal
    verification and synthesis. We introduce and investigate the extension of temporal
    logics with quantitative atomic assertions. At the heart of quantitative objectives
    lies the accumulation of values along a computation. It is often the accumulated
    sum, as with energy objectives, or the accumulated average, as with 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 (or Boolean) 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 in time. We also allow the path-accumulation assertions
    LimInfAvg(v) ≥ c and LimSupAvg(v) ≥ c, referring to the average value along an
    entire infinite computation. We study the border of decidability for such quantitative
    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 with
    both prefix-accumulation assertions, or extending LTL with both path-accumulation
    assertions, results in temporal logics whose model-checking problem is decidable.
    Moreover, the prefix-accumulation assertions may be generalized with &quot;controlled
    accumulation,&quot; allowing, for example, to specify constraints on the average
    waiting time between a request and a grant. On the negative side, we show that
    this branching-time logic is, in a sense, the maximal logic with one or both of
    the prefix-accumulation assertions that permits a decidable model-checking procedure.
    Extending a temporal logic that has the EG or EU modalities, such as CTL or LTL,
    makes the problem undecidable.

  text: 'We consider two-player zero-sum partial-observation stochastic games on graphs.
    Based on the information available to the players these games can be classified
    as follows: (a) general partial-observation (both players have partial view of
    the game); (b) one-sided partial-observation (one player has partial-observation
    and the other player has complete-observation); and (c) perfect-observation (both
    players have complete view of the game). The one-sided partial-observation games
    subsumes the important special case of one-player partial-observation stochastic
    games (or partial-observation Markov decision processes (POMDPs)). Based on the
    randomization available for the strategies, (a) the players may not be allowed
    to use randomization (pure strategies), or (b) they may choose a probability distribution
    over actions but the actual random choice is external and not visible to the player
    (actions invisible), or (c) they may use full randomization. We consider all these
    classes of games with reachability, and parity objectives that can express all
    ω-regular objectives. The analysis problems are classified into the qualitative
    analysis that asks for the existence of a strategy that ensures the objective
    with probability 1; and the quantitative analysis that asks for the existence
    of a strategy that ensures the objective with probability at least λ (0,1). In
    this talk we will cover a wide range of results: for perfect-observation games;
    for POMDPs; for one-sided partial-observation games; and for general partial-observation
    games.'

  text: 'In two-player finite-state stochastic games of partial observation on graphs,
    in every state of the graph, the players simultaneously choose an action, and
    their joint actions determine a probability distribution over the successor states.
    The game is played for infinitely many rounds and thus the players construct an
    infinite path in the graph. We consider reachability objectives where the first
    player tries to ensure a target state to be visited almost-surely (i.e., with
    probability 1) or positively (i.e., with positive probability), no matter the
    strategy of the second player. We classify such games according to the information
    and to the power of randomization available to the players. On the basis of information,
    the game can be one-sided with either (a) player 1, or (b) player 2 having partial
    observation (and the other player has perfect observation), or two-sided with
    (c) both players having partial observation. On the basis of randomization, (a)
    the players may not be allowed to use randomization (pure strategies), or (b)
    they may choose a probability distribution over actions but the actual random
    choice is external and not visible to the player (actions invisible), or (c) they
    may use full randomization. Our main results for pure strategies are as follows:
    (1) For one-sided games with player 2 having perfect observation we show that
    (in contrast to full randomized strategies) belief-based (subset-construction
    based) strategies are not sufficient, and we present an exponential upper bound
    on memory both for almost-sure and positive winning strategies; we show that the
    problem of deciding the existence of almost-sure and positive winning strategies
    for player 1 is EXPTIME-complete and present symbolic algorithms that avoid the
    explicit exponential construction. (2) For one-sided games with player 1 having
    perfect observation we show that nonelementarymemory is both necessary and sufficient
    for both almost-sure and positive winning strategies. (3) We show that for the
    general (two-sided) case finite-memory strategies are sufficient for both positive
    and almost-sure winning, and at least nonelementary memory is required. We establish
    the equivalence of the almost-sure winning problems for pure strategies and for
    randomized strategies with actions invisible. Our equivalence result exhibit serious
    flaws in previous results of the literature: we show a nonelementary memory lower
    bound for almost-sure winning whereas an exponential upper bound was previously
    claimed.'

  text: 'We study two-player concurrent games on finite-state graphs played for an
    infinite number of rounds, where 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. The objectives are ω-regular
    winning conditions specified as parity objectives. We consider the qualitative
    analysis problems: the computation of the almost-sure and limit-sure winning set
    of states, where player 1 can ensure to win with probability 1 and with probability
    arbitrarily close to 1, respectively. In general the almost-sure and limit-sure
    winning strategies require both infinite-memory as well as infinite-precision
    (to describe probabilities). While the qualitative analysis problem for concurrent
    parity games with infinite-memory, infinite-precision randomized strategies was
    studied before, we study the bounded-rationality problem for qualitative analysis
    of concurrent parity games, where the strategy set for player 1 is restricted
    to bounded-resource strategies. In terms of precision, strategies can be deterministic,
    uniform, finite-precision, or infinite-precision; and in terms of memory, strategies
    can be memoryless, finite-memory, or infinite-memory. We present a precise and
    complete characterization of the qualitative winning sets for all combinations
    of classes of strategies. In particular, we show that uniform memoryless strategies
    are as powerful as finite-precision infinite-memory strategies, and infinite-precision
    memoryless strategies are as powerful as infinite-precision finite-memory strategies.
    We show that the winning sets can be computed in (n2d+3) time, where n is the
    size of the game structure and 2d is the number of priorities (or colors), and
    our algorithms are symbolic. The membership problem of whether a state belongs
    to a winning set can be decided in NP ∩ coNP. Our symbolic algorithms are based
    on a characterization of the winning sets as μ-calculus formulas, however, our
    μ-calculus formulas are crucially different from the ones for concurrent parity
    games (without bounded rationality); and our memoryless witness strategy constructions
    are significantly different from the infinite-memory witness strategy constructions
    for concurrent parity games.'

  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: Extensionality axioms are common when reasoning about data collections, such
    as arrays and functions in program analysis, or sets in mathematics. An extensionality
    axiom asserts that two collections are equal if they consist of the same elements
    at the same indices. Using extensionality is often required to show that two collections
    are equal. A typical example is the set theory theorem (∀x)(∀y)x∪y = y ∪x. Interestingly,
    while humans have no problem with proving such set identities using extensionality,
    they are very hard for superposition theorem provers because of the calculi they
    use. In this paper we show how addition of a new inference rule, called extensionality
    resolution, allows first-order theorem provers to easily solve problems no modern
    first-order theorem prover can solve. We illustrate this by running the VAMPIRE
    theorem prover with extensionality resolution on a number of set theory and array
    problems. Extensionality resolution helps VAMPIRE to solve problems from the TPTP
    library of first-order problems that were never solved before by any prover.

  text: 'Background: The brood of ants and other social insects is highly susceptible
    to pathogens, particularly those that penetrate the soft larval and pupal cuticle.
    We here test whether the presence of a pupal cocoon, which occurs in some ant
    species but not in others, affects the sanitary brood care and fungal infection
    patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We
    use a) a comparative approach analysing four species with either naked or cocooned
    pupae and b) a within-species analysis of a single ant species, in which both
    pupal types co-exist in the same colony. Results: We found that the presence of
    a cocoon did not compromise fungal pathogen detection by the ants and that species
    with cocooned pupae increased brood grooming after pathogen exposure. All tested
    ant species further removed brood from their nests, which was predominantly expressed
    towards larvae and naked pupae treated with the live fungal pathogen. In contrast,
    cocooned pupae exposed to live fungus were not removed at higher rates than cocooned
    pupae exposed to dead fungus or a sham control. Consistent with this, exposure
    to the live fungus caused high numbers of infections and fungal outgrowth in larvae
    and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed
    the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion:
    Our study suggests that the pupal cocoon has a protective effect against fungal
    infection, causing an adaptive change in sanitary behaviours by the ants. It further
    demonstrates that brood removal - originally described for honeybees as “hygienic
    behaviour” – is a widespread sanitary behaviour in ants, which likely has important
    implications on disease dynamics in social insect colonies.'

  text: Multi-dimensional mean-payoff and energy games provide the mathematical foundation
    for the quantitative study of reactive systems, and play a central role in the
    emerging quantitative theory of verification and synthesis. In this work, we study
    the strategy synthesis problem for games with such multi-dimensional objectives
    along with a parity condition, a canonical way to express ω ω -regular conditions.
    While in general, the winning strategies in such games may require infinite memory,
    for synthesis the most relevant problem is the construction of a finite-memory
    winning strategy (if one exists). Our main contributions are as follows. First,
    we show a tight exponential bound (matching upper and lower bounds) on the memory
    required for finite-memory winning strategies in both multi-dimensional mean-payoff
    and energy games along with parity objectives. This significantly improves the
    triple exponential upper bound for multi energy games (without parity) that could
    be derived from results in literature for games on vector addition systems with
    states. Second, we present an optimal symbolic and incremental algorithm to compute
    a finite-memory winning strategy (if one exists) in such games. Finally, we give
    a complete characterization of when finite memory of strategies can be traded
    off for randomness. In particular, we show that for one-dimension mean-payoff
    parity games, randomized memoryless strategies are as powerful as their pure finite-memory
    counterparts.
