  text: "Two-player games on graphs provide the theoretical framework for many important
    problems such as reactive synthesis. While the traditional study of two-player
    zero-sum games has been extended to multi-player games with several notions of
    equilibria, they are decidable only for perfect-information games, whereas several
    applications require imperfect-information games.\r\nIn this paper we propose
    a new notion of equilibria, called doomsday equilibria, which is a strategy profile
    such that all players satisfy their own objective, and if any coalition of players
    deviates and violates even one of the players objective, then the objective of
    every player is violated.\r\nWe present algorithms and complexity results for
    deciding the existence of doomsday equilibria for various classes of ω-regular
    objectives, both for imperfect-information games, and for perfect-information
    games.We provide optimal complexity bounds for imperfect-information games, and
    in most cases for perfect-information games."

  text: We propose a method for visualizing two-dimensional symmetric positive definite
    tensor fields using the Heat Kernel Signature (HKS). The HKS is derived from the
    heat kernel and was originally introduced as an isometry invariant shape signature.
    Each positive definite tensor field defines a Riemannian manifold by considering
    the tensor field as a Riemannian metric. On this Riemmanian manifold we can apply
    the definition of the HKS. The resulting scalar quantity is used for the visualization
    of tensor fields. The HKS is closely related to the Gaussian curvature of the
    Riemannian manifold and the time parameter of the heat kernel allows a multiscale
    analysis in a natural way. In this way, the HKS represents field related scale
    space properties, enabling a level of detail analysis of tensor fields. This makes
    the HKS an interesting new scalar quantity for tensor fields, which differs significantly
    from usual tensor invariants like the trace or the determinant. A method for visualization
    and a numerical realization of the HKS for tensor fields is proposed in this chapter.
    To validate the approach we apply it to some illustrating simple examples as isolated
    critical points and to a medical diffusion tensor data set.

  text: "In this paper, we introduce planar matchings on directed pseudo-line arrangements,
    which yield a planar set of pseudo-line segments such that only matching-partners
    are adjacent. By translating the planar matching problem into a corresponding
    stable roommates problem we show that such matchings always exist.\r\nUsing our
    new framework, we establish, for the first time, a complete, rigorous definition
    of weighted straight skeletons, which are based on a so-called wavefront propagation
    process. We present a generalized and unified approach to treat structural changes
    in the wavefront that focuses on the restoration of weak planarity by finding
    planar matchings."

  text: Saddle periodic orbits are an essential and stable part of the topological
    skeleton of a 3D vector field. Nevertheless, there is currently no efficient algorithm
    to robustly extract these features. In this chapter, we present a novel technique
    to extract saddle periodic orbits. Exploiting the analytic properties of such
    an orbit, we propose a scalar measure based on the finite-time Lyapunov exponent
    (FTLE) that indicates its presence. Using persistent homology, we can then extract
    the robust cycles of this field. These cycles thereby represent the saddle periodic
    orbits of the given vector field. We discuss the different existing FTLE approximation
    schemes regarding their applicability to this specific problem and propose an
    adapted version of FTLE called Normalized Velocity Separation. Finally, we evaluate
    our method using simple analytic vector field data.

    structures without sacrificing efficiency or user-friendliness. This makes PHAT
    a versatile platform for experimenting with algorithmic ideas and comparing them
    to state of the art implementations.

  text: The spindle assembly checkpoint prevents separation of sister chromatids until
    each kinetochore is attached to the mitotic spindle. Rodriguez-Bravo et al. report
    that the nuclear pore complex scaffolds spindle assembly checkpoint signaling
    in interphase, providing a store of inhibitory signals that limits the speed of
    the subsequent mitosis.

  text: In eukaryotic cells the nuclear genome is enclosed by the nuclear envelope
    (NE). In metazoans, the NE breaks down in mitosis and it has been assumed that
    the physical barrier separating nucleoplasm and cytoplasm remains intact during
    the rest of the cell cycle and cell differentiation. However, recent studies suggest
    that nonmitotic NE remodeling plays a critical role in development, virus infection,
    laminopathies, and cancer. Although the mechanisms underlying these NE restructuring
    events are currently being defined, one common theme is activation of protein
    kinase C family members in the interphase nucleus to disrupt the nuclear lamina,
    demonstrating the importance of the lamina in maintaining nuclear integrity.

  text: The nuclear pore complex (NPC) plays a critical role in gene expression by
    mediating import of transcription regulators into the nucleus and export of RNA
    transcripts to the cytoplasm. Emerging evidence suggests that in addition to mediating
    transport, a subset of nucleoporins (Nups) engage in transcriptional activation
    and elongation at genomic loci that are not associated with NPCs. The underlying
    mechanism and regulation of Nup mobility on and off nuclear pores remain unclear.
    Here we show that Nup50 is a mobile Nup with a pronounced presence both at the
    NPC and in the nucleoplasm that can move between these different localizations.
    Strikingly, the dynamic behavior of Nup50 in both locations is dependent on active
    transcription by RNA polymerase II and requires the N-terminal half of the protein,
    which contains importin α– and Nup153-binding domains. However, Nup50 dynamics
    are independent of importin α, Nup153, and Nup98, even though the latter two proteins
    also exhibit transcription-dependent mobility. Of interest, depletion of Nup50
    from C2C12 myoblasts does not affect cell proliferation but inhibits differentiation
    into myotubes. Taken together, our results suggest a transport-independent role
    for Nup50 in chromatin biology that occurs away from the NPC.

  text: We have observed a sample of typical z ∼ 1 star-forming galaxies, selected
    from the HiZELS survey, with the new K-band Multi-Object Spectrograph (KMOS) near-infrared,
    multi-integral field unit instrument on the Very Large Telescope (VLT), in order
    to obtain their dynamics and metallicity gradients. The majority of our galaxies
    have a metallicity gradient consistent with being flat or negative (i.e. higher
    metallicity cores than outskirts). Intriguingly, we find a trend between metallicity
    gradient and specific star formation rate (sSFR), such that galaxies with a high
    sSFR tend to have relatively metal poor centres, a result which is strengthened
    when combined with data sets from the literature. This result appears to explain
    the discrepancies reported between different high-redshift studies and varying
    claims for evolution. From a galaxy evolution perspective, the trend we see would
    mean that a galaxy's sSFR is governed by the amount of metal-poor gas that can
    be funnelled into its core, triggered either by merging or through efficient accretion.
    In fact, merging may play a significant role as it is the starburst galaxies at
    all epochs, which have the more positive metallicity gradients. Our results may
    help to explain the origin of the fundamental metallicity relation, in which galaxies
    at a fixed mass are observed to have lower metallicities at higher star formation
    rates, especially if the metallicity is measured in an aperture encompassing only
    the central regions of the galaxy. Finally, we note that this study demonstrates
    the power of KMOS as an efficient instrument for large-scale resolved galaxy surveys.

  text: 'Candidate galaxies at redshifts of z ∼ 10 are now being found in extremely
    deep surveys, probing very small areas. As a consequence, candidates are very
    faint, making spectroscopic confirmation practically impossible. In order to overcome
    such limitations, we have undertaken the CF-HiZELS survey, which is a large-area,
    medium-depth near-infrared narrow-band survey targeted at z = 8.8 Lyman α (Lyα)
    emitters (LAEs) and covering 10 deg2 in part of the SSA22 field with the Canada–France–Hawaii
    Telescope (CFHT). We surveyed a comoving volume of 4.7 × 106 Mpc3 to a Lyα luminosity
    limit of 6.3 × 1043舁erg舁s−1. We look for Lyα candidates by applying the following
    criteria: (i) clear emission-line source, (ii) no optical detections (ugriz from
    CFHTLS), (iii) no visible detection in the optical stack (ugriz > 27), (iv) visually
    checked reliable NBJ and J detections and (v) J − K ≤ 0. We compute photometric
    redshifts and remove a significant amount of dusty lower redshift line-emitters
    at z ∼ 1.4 or 2.2. A total of 13 Lyα candidates were found, of which two are marked
    as strong candidates, but the majority have very weak constraints on their spectral
    energy distributions. Using follow-up observations with SINFONI/VLT, we are able
    to exclude the most robust candidates as LAEs. We put a strong constraint on the
    Lyα luminosity function at z ∼ 9 and make realistic predictions for ongoing and
    future surveys. Our results show that surveys for the highest redshift LAEs are
    susceptible of multiple contaminations and that spectroscopic follow-up is absolutely
    necessary.'

  text: We report on the magnetic properties of a hot-pressed FeSb 2 sample. We find
    a significant increase in the magnetic susceptibility in our sample when compared
    with the values previously reported for the polycrystalline sample. The pronounced
    Curie tail at low temperature corresponds to 0.2% of Fe 2+ impurities per mole.
    In the intrinsic conductivity region, the susceptibility due to free carriers
    shows thermally activated behavior and is consistent with the data reported for
    single crystal FeSb 2 . Based on our data and analysis, while the enhanced magnetic
    susceptibility in our sample comes mainly from a small amount of unreacted Fe,
    the contribution from the enhanced carrier density due to lattice and strain defects
    arising from the ball milling process is also significant. Existence of an unreacted
    Fe phase is evidenced by small coercivity values of ~100 observed at 50 and 300
    K.

  text: "We study a weighted online bipartite matching problem: G(V 1, V 2, E) is
    a weighted bipartite graph where V 1 is known beforehand and the vertices of V
    2 arrive online. The goal is to match vertices of V 2 as they arrive to vertices
    in V 1, so as to maximize the sum of weights of edges in the matching. If assignments
    to V 1 cannot be changed, no bounded competitive ratio is achievable. We study
    the weighted online matching problem with free disposal, where vertices in V 1
    can be assigned multiple times, but only get credit for the maximum weight edge
    assigned to them over the course of the algorithm. For this problem, the greedy
    algorithm is 0.5-competitive and determining whether a better competitive ratio
    is achievable is a well known open problem.\r\n\r\nWe identify an interesting
    special case where the edge weights are decomposable as the product of two factors,
    one corresponding to each end point of the edge. This is analogous to the well
    studied related machines model in the scheduling literature, although the objective
    functions are different. For this case of decomposable edge weights, we design
    a 0.5664 competitive randomized algorithm in complete bipartite graphs. We show
    that such instances with decomposable weights are non-trivial by establishing
    upper bounds of 0.618 for deterministic and 0.8 for randomized algorithms.\r\n\r\nA
    tight competitive ratio of 1 − 1/e ≈ 0.632 was known previously for both the 0-1
    case as well as the case where edge weights depend on the offline vertices only,
    but for these cases, reassignments cannot change the quality of the solution.
    Beating 0.5 for weighted matching where reassignments are necessary has been a
    significant challenge. We thus give the first online algorithm with competitive
    ratio strictly better than 0.5 for a non-trivial case of weighted matching with
    free disposal."

  text: "Assume a seller wants to sell a digital product in a social network where
    a buyer’s valuation of the item has positive network externalities from her neighbors
    that already have the item. The goal of the seller is to maximize his revenue.
    Previous work on this problem [7] studies the case where clients are offered the
    item in sequence and have to pay personalized prices. This is highly infeasible
    in large scale networks such as the Facebook graph: (1) Offering items to the
    clients one after the other consumes a large amount of time, and (2) price-discrimination
    of clients could appear unfair to them and result in negative client reaction
    or could conflict with legal requirements.\r\n\r\nWe study a setting dealing with
    these issues. Specifically, the item is offered in parallel to multiple clients
    at the same time and at the same price. This is called a round. We show that with
    O(logn) rounds, where n is the number of clients, a constant factor of the revenue
    with price discrimination can be achieved and that this is not possible with o(logn)
    rounds. Moreover we show that it is APX-hard to maximize the revenue and we give
    constant factor approximation algorithms for various further settings of limited
    price discrimination."

  text: While the penetration of objects into granular media is well-studied, there
    is little understanding of how objects settle in gravities, geff, different from
    that of Earth - a scenario potentially relevant to the geomorphology of planets
    and asteroids and also to their exploration using man-made devices. By conducting
    experiments in an accelerating frame, we explore geff ranging from 0.4 g to 1.2
    g. Surprisingly, we find that the rest depth is independent of geff and also that
    the time required for the object to come to rest scales like geff-1/2. With discrete
    element modeling simulations, we reproduce the experimental results and extend
    the range of geff to objects as small as asteroids and as large as Jupiter. Our
    results shed light on the initial stage of sedimentation into dry granular media
    across a range of celestial bodies and also have implications for the design of
    man-made, extraterrestrial vehicles and structures. Key Points The settling depth
    in granular media is independent of gravity The settling time scales like g-1/2
    Layering driven by granular sedimentation should be similar.

  text: 'The decremental single-source shortest paths (SSSP) problem concerns maintaining
    the distances between a given source node s to every node in an n-node m-edge
    graph G undergoing edge deletions. While its static counterpart can be easily
    solved in near-linear time, this decremental problem is much more challenging
    even in the undirected unweighted case. In this case, the classic O(mn) total
    update time of Even and Shiloach (JACM 1981) has been the fastest known algorithm
    for three decades. With the loss of a (1 + ε)-approximation factor, the running
    time was recently improved to O(n 2+o(1) ) by Bernstein and Roditty (SODA 2011),
    and more recently to O(n 1.8+o(1) + m 1+o(1) ) by Henzinger, Krinninger, and Nanongkai
    (SODA 2014). In this paper, we finally bring the running time of this case down
    to near-linear: We give a (1 + ε)-approximation algorithm with O(m 1+o(1) ) total
    update time, thus obtaining near-linear time. Moreover, we obtain O(m 1+o(1) log
    W) time for the weighted case, where the edge weights are integers from 1 to W.
    The only prior work on weighted graphs in o(mn log W) time is the O(mn 0.986 log
    W)-time algorithm by Henzinger, Krinninger, and Nanongkai (STOC 2014) which works
    for the general weighted directed case. In contrast to the previous results which
    rely on maintaining a sparse emulator, our algorithm relies on maintaining a so-called
    sparse (d, ε)-hop set introduced by Cohen (JACM 2000) in the PRAM literature.
    A (d, ε)-hop set of a graph G = (V, E) is a set E'' of weighted edges such that
    the distance between any pair of nodes in G can be (1 + ε)-approximated by their
    d-hop distance (given by a path containing at most d edges) on G''=(V, E∪E'').
    Our algorithm can maintain an (n o(1) , ε)-hop set of near-linear size in near-linear
    time under edge deletions. It is the first of its kind to the best of our knowledge.
    To maintain the distances on this hop set, we develop a monotone bounded-hop Even-Shiloach
    tree. It results from extending and combining the monotone Even-Shiloach tree
    of Henzinger, Krinninger, and Nanongkai (FOCS 2013) with the bounded-hop SSSP
    technique of Bernstein (STOC 2013). These two new tools might be of independent
    interest.'

  text: "We consider dynamic algorithms for maintaining Single-Source Reachability
    (SSR) and approximate Single-Source Shortest Paths (SSSP) on n-node m-edge directed
    graphs under edge deletions (decremental algorithms). The previous fastest algorithm
    for SSR and SSSP goes back three decades to Even and Shiloach (JACM 1981); it
    has O(1) query time and O(mn) total update time (i.e., linear amortized update
    time if all edges are deleted). This algorithm serves as a building block for
    several other dynamic algorithms. The question whether its total update time can
    be improved is a major, long standing, open problem.\r\n\r\nIn this paper, we
    answer this question affirmatively. We obtain a randomized algorithm which, in
    a simplified form, achieves an Õ(mn0.984) expected total update time for SSR and
    (1 + ε)-approximate SSSP, where Õ(·) hides poly log n. We also extend our algorithm
    to achieve roughly the same running time for Strongly Connected Components (SCC),
    improving the algorithm of Roditty and Zwick (FOCS 2002), and an algorithm that
    improves the Õ (mn log W)-time algorithm of Bernstein (STOC 2013) for approximating
    SSSP on weighted directed graphs, where the edge weights are integers from 1 to
    W. All our algorithms have constant query time in the worst case."

  text: We present the first deterministic data structures for maintaining approximate
    minimum vertex cover and maximum matching in a fully dynamic graph in  time per
    update. In particular, for minimum vertex cover we provide deterministic data
    structures for maintaining a (2 + ε) approximation in O(log n/ε2) amortized time
    per update. For maximum matching, we show how to maintain a (3 + e) approximation
    in O(m1/3/ε2) amortized time per update, and a (4 + ε) approximation in O(m1/3/ε2)
    worst-case time per update. Our data structure for fully dynamic minimum vertex
    cover is essentially near-optimal and settles an open problem by Onak and Rubinfeld
    [13].

  text: "We study dynamic (1 + ∊)-approximation algorithms for the single-source shortest
    paths problem in an unweighted undirected n-node m-edge graph under edge deletions.
    The fastest algorithm for this problem is an algorithm with O(n2+o(1)) total update
    time and constant query time by Bernstein and Roditty (SODA 2011). In this paper,
    we improve the total update time to O(n1.8+o(1) + m1+o(1)) while keeping the query
    time constant. This running time is essentially tight when m = Ω(n1.8) since we
    need Ω(m) time even in the static setting. For smaller values of m, the running
    time of our algorithm is subquadratic, and is the first that breaks through the
    quadratic time barrier.\r\n\r\nIn obtaining this result, we develop a fast algorithm
    for what we call center cover data structure. We also make non-trivial extensions
    to our previous techniques called lazy-update and monotone Even-Shiloach trees
    (ICALP 2013 and FOCS 2013). As by-products of our new techniques, we obtain two
    new results for the decremental all-pairs shortest-paths problem. Our first result
    is the first approximation algorithm whose total update time is faster than Õ(mn)
    for all values of m. Our second result is a new trade-off between the total update
    time and the additive approximation guarantee."

  text: Observations of flowing granular matter have suggested that same-material
    tribocharging depends on particle size, typically rendering large grains positive
    and small ones negative. Models assuming the transfer of trapped electrons can
    account for this trend, but have not been validated. Tracking individual grains
    in an electric field, we show quantitatively that charge is transferred based
    on size between materially identical grains. However, the surface density of trapped
    electrons, measured independently by thermoluminescence techniques, is orders
    of magnitude too small to account for the scale of charge transferred. This reveals
    that trapped electrons are not a necessary ingredient for same-material tribocharging.

  text: An experimentally easy to perform method for the generation of alumina-supported
    Fe3O4 nanoparticles [(6±1) nm size, 0.67 wt %]and the use of this material in
    hydrazine-mediated heterogeneously catalyzed reductions of nitroarenes to anilines
    under batch and continuous-flow conditions is presented. The bench-stable, reusable
    nano-Fe3O4@Al2O3 catalyst can selectively reduce functionalized nitroarenes at
    1 mol % catalyst loading by using a 20 mol % excess of hydrazine hydrate in an
    elevated temperature regime (150 °C, reaction time 2–6 min in batch). For continuous-flow
    processing, the catalyst material is packed into dedicated cartridges and used
    in a commercially available high-temperature/-pressure flow device. In continuous
    mode, reaction times can be reduced to less than 1 min at 150 °C (30 bar back
    pressure) in a highly intensified process. The nano-Fe3O4@Al2O3 catalyst demonstrated
    stable reduction of nitrobenzene (0.5 M in MeOH) for more than 10 h on stream
    at a productivity of 30 mmol h−1 (0.72 mol per day). Importantly, virtually no
    leaching of the catalytically active material could be observed by inductively
    coupled plasma MS monitoring.
