  text: We use the lac operon in Escherichia coli as a prototype system to illustrate
    the current state, applicability, and limitations of modeling the dynamics of
    cellular networks. We integrate three different levels of description (molecular,
    cellular, and that of cell population) into a single model, which seems to capture
    many experimental aspects of the system.

  text: Kv3 channels are thought to be essential for the fast-spiking (FS) phenotype
    in GABAergic interneurons, but how these channels confer the ability to generate
    action potentials (APs) at high frequency is unknown. To address this question,
    we developed a fast dynamic-clamp system (approximately 50 kHz) that allowed us
    to add a Kv3 model conductance to CA1 oriens alveus (OA) interneurons in hippocampal
    slices. Selective pharmacological block of Kv3 channels by 0.3 mm 4-aminopyridine
    or 1 mm tetraethylammonium ions led to a marked broadening of APs during trains
    of short stimuli and a reduction in AP frequency during 1 sec stimuli. The addition
    of artificial Kv3 conductance restored the original AP pattern. Subtraction of
    Kv3 conductance by dynamic clamp mimicked the effects of the blockers. Application
    of artificial Kv3 conductance also led to FS in OA interneurons after complete
    K+ channel block and even induced FS in hippocampal pyramidal neurons in the absence
    of blockers. Adding artificial Kv3 conductance with altered deactivation kinetics
    revealed a nonmonotonic relationship between mean AP frequency and deactivation
    rate, with a maximum slightly above the original value. Insertion of artificial
    Kv3 conductance with either lowered activation threshold or inactivation also
    led to a reduction in the mean AP frequency. However, the mechanisms were distinct.
    Shifting the activation threshold induced adaptation, whereas adding inactivation
    caused frequency-dependent AP broadening. In conclusion, Kv3 channels are necessary
    for the FS phenotype of OA interneurons, and several of their gating properties
    appear to be optimized for high-frequency repetitive activity.

  text: To probe exocytosis at a cortical glutamatergic synapse, we made capacitance
    measurements in whole-cell recorded hippocampal mossy fiber terminals. Evaluation
    of different methods by using a morphology-based equivalent electrical model revealed
    that quantitative capacitance measurements are possible in this presynaptic structure.
    Voltage pulses leading to presynaptic Ca2+ inflow evoked large capacitance signals
    that showed saturation with increasing pulse duration. The mean peak capacitance
    increase was 100 fF, corresponding to a pool of approximately 1,400 releasable
    vesicles. Thus hippocampal mossy fiber synapses have a vesicular &quot;maxipool.&quot;
    Large pool size and rapid vesicle recycling may underlie the uniquely large extent
    of activity-dependent plasticity in this synapse.

  text: Many verification, planning, and control problems can be modeled as games
    played on state-transition graphs by one or two players whose conflicting goals
    are to form a path in the graph. The focus here is on simple stochastic parity
    games, that is, two-player games with turn-based probabilistic transitions and
    omega-regular objectives formalized as parity (Rabin chain) winning conditions.
    An efficient translation from simple stochastic parity games to nonstochastic
    parity games is given. As many algorithms are known for solving the latter, the
    translation yields efficient algorithms for computing the states of a simple stochastic
    parity game from which a player can win with probability 1. An important special
    case of simple stochastic parity games are the Markov decision processes with
    Buchi objectives. For this special case a first provably subquadratic algorithm
    is given for computing the states from which the single player has a strategy
    to achieve a Buchi objective with probability 1. For game graphs with m edges
    the algorithm works in time O(mrootm). Interestingly, a similar technique sheds
    light on the question of the computational complexity of solving simple Buchi
    games and yields the first provably subquadratic algorithm, with a running time
    of O(n(2)/log n) for game graphs with n vertices and O(n) edges.

  text: We study the problem of determining stack boundedness and the exact maximum
    stack size for three classes of interrupt-driven programs. Interrupt-driven programs
    axe used in many real-time applications that require responsive interrupt handling.
    In order to ensure responsiveness, programmers often enable interrupt processing
    in the body of lower-priority interrupt handlers. In such programs a programming
    error can allow interrupt handlers to be interrupted in cyclic fashion to lead
    to an unbounded stack, causing the system to crash. For a restricted class of
    interrupt-driven programs, we show that there is a polynomial-time procedure to
    check stack boundedness, while determining the exact maximum stack size is PSPACE-complete.
    For a larger class of programs, the two problems are both PSPACE-complete, and
    for the largest class of programs we consider, the two problems are PSPACE-hard
    and can be solved in exponential time.

  text: 'Unlike most social insects, many Cardiocondyla ant species have two male
    morphs: wingless (ergatoid) males, who remain in the natal nest, and winged males
    who disperse but, strangely, before leaving may also mate within the nest. Whereas
    ergatoid males are highly intolerant of each other and fight among themselves,
    they tend to tolerate their winged counterparts. This is despite the fact that
    these winged males, like ergatoid males, represent mating competition. Why should
    ergatoid males tolerate their winged rivals? We developed a mathematical model
    to address this question. Our model focuses on a number of factors likely toinfluence
    whether ergatoid males are tolerant of winged males: ergatoid male–winged male
    relatedness, number of virgin queens, number of winged males, and the number of
    ejaculates a winged male has (winged males are sperm limited, whereas ergatoid
    males have lifelong spermatogenesis). Surprisingly, we found that increasing the
    number of virgin queens favors a kill strategy, whereas an increase in the other
    factors favors a let-live strategy; these predictions appear true for C. obscurior
    and for a number of other Cardiocondyla species. Two further aspects, unequal
    insemination success and multiple mating in queens, were also incorporated into
    the model and predictions made about their effects on toleration of winged males.
    The model is applicable more generally in species that have dimorphic males, such
    as some other ants, bees, and fig wasps.'

  text: Dispersal is advantageous, but, at the same time, it implies high costs and
    risks. Due to these counteracting selection pressures, many species evolved dispersal
    polymorphisms, which, in ants, are typically restricted to the female sex (queens).
    Male polymorphism is presently only known from a few genera, such as Cardiocondyla,
    in which winged dispersing males coexist with wingless fighter males that mate
    exclusively inside their maternal nests. We studied the developmental mechanisms
    underlying these alternative male morphs and found that, first, male dimorphism
    is not genetically determined, but is induced by environmental conditions (decreasing
    temperature and density). Second, male morph is not yet fixed at the egg stage,
    but it differentiates during larval development. This flexible developmental pattern
    of male morphs allows Cardiocondyla ant colonies to react quickly to changes in
    their environment. Under good conditions, they invest exclusively in philopatric
    wingless males. But, when environmental conditions turn bad, colonies start to
    produce winged dispersal males, even though these males require a many times higher
    investment by the colony than their much smaller wingless counterparts. Cardiocondyla
    ants share this potential of optimal resource allocation with other colonial animals
    and some seed dimorphic plants.

  text: Computing the volume occupied by individual atoms in macromolecular structures
    has been the subject of research for several decades. This interest has grown
    in the recent years, because weighted volumes are widely used in implicit solvent
    models. Applications of the latter in molecular mechanics simulations require
    that the derivatives of these weighted volumes be known. In this article, we give
    a formula for the volume derivative of a molecule modeled as a space-filling diagram
    made up of balls in motion. The formula is given in terms of the weights, radii,
    and distances between the centers as well as the sizes of the facets of the power
    diagram restricted to the space-filling diagram. Special attention is given to
    the detection and treatment of singularities as well as discontinuities of the
    derivative.

  text: We present algorithms for constructing a hierarchy of increasingly coarse
    Morse-Smale complexes that decompose a piecewise linear 2-manifold. While these
    complexes are defined only in the smooth category, we extend the construction
    to the piecewise linearcategory by ensuring structural integrity and simulating
    differentiability. We then simplify Morse-Smale complexes by canceling pairs of
    critical points in order of increasing persistence.

  text: The body defined by a finite collection of disks is a subset of the plane
    bounded by a tangent continuous curve, which we call the skin. We give analytic
    formulas for the area, the perimeter, the area derivative, and the perimeter derivative
    of the body. Given the filtrations of the Delaunay triangulation and the Voronoi
    diagram of the disks, all formulas can be evaluated in time proportional to the
    number of disks.

  text: We combine topological and geometric methods to construct a multi-resolution
    data structure for functions over two-dimensional domains. Starting with the Morse-Smale
    complex, we construct a topological hierarchy by progressively canceling critical
    points in pairs. Concurrently, we create a geometric hierarchy by adapting the
    geometry to the changes in topology. The data structure supports mesh traversal
    operations similarly to traditional multi-resolution representations.

  text: During vertebrate gastrulation, highly coordinated cellular rearrangements
    lead to the formation of the three germ layers, ectoderm, mesoderm and endoderm.
    In zebrafish, silberblick (slb)/wnt11 regulates normal gastrulation movements
    by activating a signalling pathway similar to the Frizzled-signalling pathway,
    which establishes epithelial planar cell polarity (PCP) in Drosophila. However,
    the cellular mechanisms by which slb/wnt11 functions during zebrafish gastrulation
    are still unclear. Using high-resolution two-photon confocal imaging followed
    by computer-assisted reconstruction and motion analysis, we have analysed the
    movement and morphology of individual cells in three dimensions during the course
    of gastrulation. We show that in slb-mutant embryos, hypoblast cells within the
    forming germ ring have slower, less directed migratory movements at the onset
    of gastrulation. These aberrant cell movements are accompanied by defects in the
    orientation of cellular processes along the individual movement directions of
    these cells. We conclude that slb/wnt11-mediated orientation of cellular processes
    plays a role in facilitating and stabilising movements of hypoblast cells in the
    germ ring, thereby pointing at a novel function of the slb/wnt11 signalling pathway
    for the regulation of migratory cell movements at early stages of gastrulation.

  text: 'Background: During vertebrate gastrulation, cell polarization and migration
    are core components in the cellular rearrangements that lead to the formation
    of the three germ layers, ectoderm, mesoderm, and endoderm. Previous studies have
    implicated the Wnt/planar cell polarity (PCP) signaling pathway in controlling
    cell morphology and movement during gastrulation. However, cell polarization and
    directed cell migration are reduced but not completely abolished in the absence
    of Wnt/PCP signals; this observation indicates that other signaling pathways must
    be involved. Results: We show that Phosphoinositide 3-Kinases (PI3Ks) are required
    at the onset of zebrafish gastrulation in mesendodermal cells for process formation
    and cell polarization. Platelet Derived Growth Factor (PDGF) functions upstream
    of PI3K, while Protein Kinase B (PKB), a downstream effector of PI3K activity,
    localizes to the leading edge of migrating mesendodermal cells. In the absence
    of PI3K activity, PKB localization and cell polarization are strongly reduced
    in mesendodermal cells and are followed by slower but still highly coordinated
    and directed movements of these cells. Conclusions: We have identified a novel
    role of a signaling pathway comprised of PDGF, PI3K, and PKB in the control of
    morphogenetic cell movements during gastrulation. Furthermore, our findings provide
    insight into the relationship between cell polarization and directed cell migration
    at the onset of zebrafish gastrulation.'

  text: Wnt genes play important roles in regulating patterning and morphogenesis
    during vertebrate gastrulation. In zebrafish, slb/wnt11 is required for convergence
    and extension movements, but not cell fate specification during gastrulation.
    To determine if other Wnt genes functionally interact with slb/wnt11, we analysed
    the role of ppt/wnt5 during zebrafish gastrulation. ppt/wnt5 is maternally provided
    and zygotically expressed at all stages during gastrulation. The analysis of ppt
    mutant embryos reveals that Ppt/Wnt5 regulates cell elongation and convergent
    extension movements in posterior regions of the gastrula, while its function in
    more anterior regions is largely redundant to that of Slb/Wnt11. Frizzled-2 functions
    downstream of ppt/wnt5, indicating that it might act as a receptor for Ppt/Wnt5
    in this process. The characterisation of the role of Ppt/Wnt5 provides insight
    into the functional diversity of Wnt genes in regulating vertebrate gastrulation
    movements. (C) 2003 Elsevier Science Ireland Ltd. All rights reserved.

  text: Chromosomal rearrangements can promote reproductive isolation by reducing
    recombination along a large section of the genome. We model the effects of the
    genetic barrier to gene flow caused by a chromosomal rearrangement on the rate
    of accumulation of postzygotic isolation genes in parapatry. We find that, if
    reproductive isolation is produced by the accumulation in parapatry of sets of
    alleles compatible within but incompatible across species, chromosomal rearrangements
    are far more likely to favor it than classical genetic barriers without chromosomal
    changes. New evidence of the role of chromosomal rearrangements in parapatric
    speciation suggests that postzygotic isolation is often due to the accumulation
    of such incompatibilities. The model makes testable qualitative predictions about
    the genetic signature of speciation.
