  text: Asteroseismology provides global stellar parameters such as masses, radii,
    or surface gravities using mean global seismic parameters and effective temperature
    for thousands of low-mass stars (0.8 M⊙ < M < 3 M⊙). This methodology has been
    successfully applied to stars in which acoustic modes excited by turbulent convection
    are measured. Other methods such as the Flicker technique can also be used to
    determine stellar surface gravities, but only works for log g above 2.5 dex. In
    this work, we present a new metric called FliPer (Flicker in spectral power density,
    in opposition to the standard Flicker measurement which is computed in the time
    domain); it is able to extend the range for which reliable surface gravities can
    be obtained (0.1 < log g < 4.6 dex) without performing any seismic analysis for
    stars brighter than Kp < 14. FliPer takes into account the average variability
    of a star measured in the power density spectrum in a given range of frequencies.
    However, FliPer values calculated on several ranges of frequency are required
    to better characterize a star. Using a large set of asteroseismic targets it is
    possible to calibrate the behavior of surface gravity with FliPer through machine
    learning. This calibration made with a random forest regressor covers a wide range
    of surface gravities from main-sequence stars to subgiants and red giants, with
    very small uncertainties from 0.04 to 0.1 dex. FliPer values can be inserted in
    automatic global seismic pipelines to either give an estimation of the stellar
    surface gravity or to assess the quality of the seismic results by detecting any
    outliers in the obtained νmax values. FliPer also constrains the surface gravities
    of main-sequence dwarfs using only long-cadence data for which the Nyquist frequency
    is too low to measure the acoustic-mode properties.

  text: "The recently launched NASA Transiting Exoplanet Survey Satellite (TESS) mission
    is going to collect lightcurves for a few hundred million of stars and we expect
    to increase the number of pulsating stars to analyze compared to the few thousand
    stars observed by the CoRoT, Kepler and K2 missions. However, most of the TESS
    targets have not yet been properly classified and characterized. In order to improve
    the analysis of the TESS data, it is crucial to determine the type of stellar
    pulsations in a timely manner. We propose an automatic method to classify stars
    attending to their pulsation properties, in particular, to identify solar-like
    pulsators among all TESS targets. It relies on the use of the global amount of
    power contained in the power spectrum (already known as the FliPer method) as
    a key parameter, along with\r\nthe effective temperature, to feed into a machine
    learning classifier. Our study, based on TESS simulated datasets, shows that we
    are able to classify pulsators with a 98% accuracy."

  text: Our understanding of stars through asteroseismic data analysis is limited
    by our ability to take advantage of the huge amount of observed stars provided
    by space missions such as CoRoT, Kepler , K2, and soon TESS and PLATO. Global
    seismic pipelines provide global stellar parameters such as mass and radius using
    the mean seismic parameters, as well as the effective temperature. These pipelines
    are commonly used automatically on thousands of stars observed by K2 for 3 months
    (and soon TESS for at least ∼ 1 month). However, pipelines are not immune from
    misidentifying noise peaks and stellar oscillations. Therefore, new validation
    techniques are required to assess the quality of these results. We present a new
    metric called FliPer (Flicker in Power), which takes into account the average
    variability at all measured time scales. The proper calibration of FliPer enables
    us to obtain good estimations of global stellar parameters such as surface gravity
    that are robust against the influence of noise peaks and hence are an excellent
    way to find faults in asteroseismic pipelines.

  text: Segmentation is the process of partitioning digital images into meaningful
    regions. The analysis of biological high content images often requires segmentation
    as a first step. We propose ilastik as an easy-to-use tool which allows the user
    without expertise in image processing to perform segmentation and classification
    in a unified way. ilastik learns from labels provided by the user through a convenient
    mouse interface. Based on these labels, ilastik infers a problem specific segmentation.
    A random forest classifier is used in the learning step, in which each pixel's
    neighborhood is characterized by a set of generic (nonlinear) features. ilastik
    supports up to three spatial plus one spectral dimension and makes use of all
    dimensions in the feature calculation. ilastik provides realtime feedback that
    enables the user to interactively refine the segmentation result and hence further
    fine-tune the classifier. An uncertainty measure guides the user to ambiguous
    regions in the images. Real time performance is achieved by multi-threading which
    fully exploits the capabilities of modern multi-core machines. Once a classifier
    has been trained on a set of representative images, it can be exported and used
    to automatically process a very large number of images (e.g. using the CellProfiler
    pipeline). ilastik is an open source project and released under the BSD license
    at www.ilastik.org.

  text: "The purpose of this paper is to construct examples of diffusion for E-Hamiltonian
    perturbations\r\nof completely integrable Hamiltonian systems in 2d-dimensional
    phase space, with d large.\r\nIn the first part of the paper, simple and explicit
    examples are constructed illustrating absence\r\nof ‘long-time’ stability for
    size E Hamiltonian perturbations of quasi-convex integrable systems\r\nalready
    when the dimension 2d of phase space becomes as large as log 1/E . We first produce\r\nthe
    example in Gevrey class and then a real analytic one, with some additional work.\r\nIn
    the second part, we consider again E-Hamiltonian perturbations of completely integrable\r\nHamiltonian
    system in 2d-dimensional space with E-small but not too small, |E| > exp(−d),
    with\r\nd the number of degrees of freedom assumed large. It is shown that for
    a class of analytic\r\ntime-periodic perturbations, there exist linearly diffusing
    trajectories. The underlying idea for\r\nboth examples is similar and consists
    in coupling a fixed degree of freedom with a large\r\nnumber of them. The procedure
    and analytical details are however significantly different. As\r\nmentioned, the
    construction in Part I is totally elementary while Part II is more involved, relying\r\nin
    particular on the theory of normally hyperbolic invariant manifolds, methods of
    generating\r\nfunctions, Aubry–Mather theory, and Mather’s variational methods."

  text: 'We present a model for edge updates with restricted randomness in dynamic
    graph algorithms and a general technique for analyzing the expected running time
    of an update operation. This model is able to capture the average case in many
    applications, since (1) it allows restrictions on the set of edges which can be
    used for insertions and (2) the type (insertion or deletion) of each update operation
    is arbitrary, i.e., not random. We use our technique to analyze existing and new
    dynamic algorithms for the following problems: maximum cardinality matching, minimum
    spanning forest, connectivity, 2-edge connectivity, k -edge connectivity, k -vertex
    connectivity, and bipartiteness. Given a random graph G with m 0 edges and n vertices
    and a sequence of l update operations such that the graph contains m i edges after
    operation i , the expected time for performing the updates for any l is O(llogn+∑li=1n/m−−√i)
    in the case of minimum spanning forests, connectivity, 2-edge connectivity, and
    bipartiteness. The expected time per update operation is O(n) in the case of maximum
    matching. We also give improved bounds for k -edge and k -vertex connectivity.
    Additionally we give an insertions-only algorithm for maximum cardinality matching
    with worst-case O(n) amortized time per insertion.'

  text: "In the present paper, we give a definition of prevalent (\"metrically prevalent\"
    ) sets in nonlinear function\r\nspaces. A subset of a Euclidean space is said
    to be metrically prevalent if its complement has measure zero.\r\nThere is no
    natural way to generalize the definition of a set of measure zero in a finite-dimensional
    space\r\nto the infinite-dimensional case [6]. Therefore, it is necessary to give
    a special definition of a metrically\r\nprevalent set (set of full measure) in
    an infinite-dimensional space. There are various ways to do so. We\r\nsuggest
    one of the possible ways to define the class of metrically prevalent sets in the
    space of smooth maps\r\nof one smooth manifold into another. It is shown in this
    paper that the class of metrically prevalent sets\r\nhas natural properties; in
    particular, the intersection of finitely many metrically prevalent sets is metrically\r\nprevalent.
    The main result of the paper is a prevalent version of Thorn's transversality
    theorem.\r\nIt is common practice in singularity theory and the theory of dynamical
    systems to say that a property\r\nholds for \"almost every\" map (or flow) if
    it holds for a residual set, i.e., a set that contains a countable\r\nintersection
    of open dense sets in the corresponding function space. However, even in finite-dimensional\r\nspaces
    such a set can have arbitrarily small (say, zero) Lebesgue measure. We prove that
    Thorn's transversality theorem holds for an essentially \"thicker\" set than a
    residual set. It seems reasonable to revise from\r\nthe prevalent point of view
    the classical results of singularity theory and theory of dynamical systems,\r\nincluding
    the multijet transversality theorem, Mather's stability theorem, Kupka-Smale's
    theorem for dynamical systems, etc. We shall do this elsewhere. The notion of
    prevalence in linear Banach spaces was\r\nintroduced and investigated in [8].
    One of the possible ways to define a class of prevalent sets in the space\r\nof
    smooth maps of manifolds, which essentially differs from that presented in this
    paper, is given in [7].\r\nDefinitions of typicalness based on the Lebesgue measure
    in a finite-dimensional space were suggested\r\nby Kolmogorov [10] and Arnold
    [11]. These definitions were cited and discussed in [9]. Here we only point\r\nout
    that the finite-dimensional analog of Arnold's definition allows prevalent sets
    to have arbitrarily small\r\nmeasure, whereas the prevalent sets in the sense
    of the finite-dimensional analog of the definition given in\r\nthe present paper
    are necessarily of full measure. Our definition is a modification of that due
    to Arnold.\r\nI wish to thank Yu. S. Illyashenko for constant attention to this
    work and useful discussions and\r\nR. I. Bogdanov for help in the preparation
    of this paper. "

  text: 'The tra-1 gene is a terminal regulator of somatic sex in Caenorhabditis elegans:
    high tra-1 activity elicits female development, low tra-1 activity elicits male
    development. To investigate the function and evolution of tra- 1, we examined
    the tra-1 gene from the closely related nematode C. briggsae. Ce-tra-1 and Cb-tra-1
    are unusually divergent. Each gene generates two transcripts, but only one of
    these is present in both species. This common transcript encodes TRA-1A, which
    shows only 44% amino acid identity between the species, a figure much lower than
    that for previously compared genes. A Cb-tra-1 transgene rescues many tissues
    of tra-1(null) mutants of C. elegans but not the somatic gonad or germ line. This
    transgene also causes nongonadal feminization of XO animals, indicating incorrect
    sexual regulation. Alignment of Ce-TRA-1A and Cb-TRA-1A defined several conserved
    regions likely to be important for tra-1 function. The phenotype differences between
    Ce-tra- 1(null) mutants rescued by Cb-tra-1 transgenes and wild-type C. elegans
    indicate significant divergence of regulatory regions. These molecular and functional
    studies suggest that evolution of sex determination in nematodes is rapid and
    genetically complex.'
