  text: Previous estimates of melt and surface sublimation on glaciers of the subtropical
    semiarid Andes (29–34°S) have been obtained at few specific locations, but it
    is not clear how ablation components vary across the entire extent of a glacier
    in this dry environment. Here, we simulate the distributed energy and mass balance
    of Juncal Norte Glacier (33°S) during a 2-month summer period. Forcing fields
    of near-surface air temperature and wind speed are generated using two methods
    accounting for the main physical processes that shape their spatial variations.
    Simulated meteorological variables and ablation agree well with observations on
    the glacier tongue and reveal complex patterns of energy and mass fluxes. Ablation
    decreases from 70 mm w.e. d<jats:sup>−1</jats:sup> at the low-albedo glacier terminus
    (~3000 m), where almost 100% of total ablation corresponds to melt, to &lt;5 mm
    w.e. d<jats:sup>−1</jats:sup> at wind-exposed, strong-radiated sites above 5500
    m, where surface sublimation represents &gt;75% of total ablation. Our simulations
    provide the first glacier-scale estimates of ablation components on a glacier
    in the study region and better reproduce the observed and expected spatial variations
    of melt and surface sublimation, in comparison with more simple assumptions, such
    as linear gradients and uniform wind speeds.

  text: The hydrological systems of heavily-downwasted debris-covered glaciers differ
    from those of clean-ice glaciers due to the hummocky surface and debris mantle
    of such glaciers, leading to a relatively limited understanding of drainage pathways.
    Supraglacial ponds represent sinks within the discontinuous supraglacial drainage
    system, and occasionally drain englacially. To assess pond dynamics, we made pond
    water level measurements on Lirung Glacier, Nepal, during May and October of 2013
    and 2014. Simultaneously, aerial, satellite, and terrestrial orthoimages and digital
    elevation models were obtained, providing snapshots of the ponds and their surroundings.
    We performed a DEM-based analysis of the glacier's closed surface catchments to
    identify surface drainage pathways and englacial drainage points, and compared
    this to field observations of surface and near-surface water flow. The total ponded
    area was higher in the pre-monsoon than post-monsoon, with individual ponds filling
    and draining seasonally associated with the surface exposure of englacial conduit
    segments. We recorded four pond drainage events, all of which occurred gradually
    (duration of weeks), observed diurnal fluctuations indicative of varying water
    supply and outflow discharge, and we documented instances of interaction between
    distant ponds. The DEM drainage analysis identified numerous sinks >3 m in depth
    across the glacier surface, few of which exhibited ponds (23%), while the field
    survey highlighted instances of surface water only explicable via englacial routes.
    Taken together, our observations provide evidence for widespread supraglacial-englacial
    connectivity of meltwater drainage paths. Results suggest that successive englacial
    conduit collapse events, themselves likely driven by supraglacial pond drainage,
    cause the glacier surface drainage system to evolve into a configuration following
    relict englacial conduit systems. Within this system, ponds form in depressions
    of reduced drainage efficiency and link the supraglacial and englacial drainage
    networks.

  text: 'We investigate the energy balance and ablation regimes of glaciers in high-elevation,
    dry environments using glaciometeorological data collected on six glaciers in
    the semiarid Andes of North-Central Chile (29–34°S, 3127–5324 m). We use a point-scale
    physically based energy balance (EB) model and an enhanced Temperature-Index (ETI)
    model that calculates melt rates only as a function of air temperature and net
    shortwave radiation. At all sites, the largest energy inputs are net shortwave
    and incoming longwave radiation, which are controlled by surface albedo and elevation,
    respectively. Turbulent fluxes cancel each other out at the lower sites, but as
    elevation increases, cold, dry and wind-exposed conditions increase the magnitude
    of negative latent heat fluxes, associated with large surface sublimation rates.
    In midsummer (January), ablation rates vary from 67.9 mm w.e. d−1 at the lowest
    site (∼100% corresponding to melt), to 2.3 mm w.e. d−1 at the highest site (>85%
    corresponding to surface sublimation). At low-elevation, low-albedo, melt-dominated
    sites, the ETI model correctly reproduces melt using a large range of possible
    parameters, but both the performance and parameter transferability decrease with
    elevation for two main reasons: (i) the air temperature threshold approach for
    melt onset does not capture the diurnal variability of melt in cold and strong
    irradiated environments and (ii) energy losses decrease the correlation between
    melt and net shortwave radiation. We summarize our results by means of an elevation
    profile of ablation components that can be used as reference in future studies
    of glacier ablation in the semiarid Andes.'

  text: Supraglacial ponds play a key role in absorbing atmospheric energy and directing
    it to the ice of debris-covered glaciers, but the spatial and temporal distribution
    of these features is not well documented. We analyse 172 Landsat TM/ETM+ scenes
    for the period 1999–2013 to identify thawed supraglacial ponds for the debris-covered
    tongues of five glaciers in the Langtang Valley of Nepal. We apply an advanced
    atmospheric correction routine (Landcor/6S) and use band ratio and image morphological
    techniques to identify ponds and validate our results with 2.5 m Cartosat-1 observations.
    We then characterize the spatial, seasonal and interannual patterns of ponds.
    We find high variability in pond incidence between glaciers (May–October means
    of 0.08–1.69% of debris area), with ponds most frequent in zones of low surface
    gradient and velocity. The ponds show pronounced seasonality, appearing in the
    pre-monsoon as snow melts, peaking at the monsoon onset at 2% of debris-covered
    area, then declining in the post-monsoon as ponds drain or freeze. Ponds are highly
    recurrent and persistent, with 40.5% of pond locations occurring for multiple
    years. Rather than a trend in pond cover over the study period, we find high interannual
    variability for each glacier after controlling for seasonality.

  text: We study controller synthesis problems for finite-state Markov decision processes,
    where the objective is to optimize the expected mean-payoff performance and stability
    (also known as variability in the literature). We argue that the basic notion
    of expressing the stability using the statistical variance of the mean payoff
    is sometimes insufficient, and propose an alternative definition. We show that
    a strategy ensuring both the expected mean payoff and the variance below given
    bounds requires randomization and memory, under both the above definitions. We
    then show that the problem of finding such a strategy can be expressed as a set
    of constraints.

  text: "Transforming deterministic ω\r\n-automata into deterministic parity automata
    is traditionally done using variants of appearance records. We present a more
    efficient variant of this approach, tailored to Rabin automata, and several optimizations
    applicable to all appearance records. We compare the methods experimentally and
    find out that our method produces smaller automata than previous approaches. Moreover,
    the experiments demonstrate the potential of our method for LTL synthesis, using
    LTL-to-Rabin translators. It leads to significantly smaller parity automata when
    compared to state-of-the-art approaches on complex formulae."

  text: Engineering and enhancing the breaking of inversion symmetry in solids—that
    is, allowing electrons to differentiate between ‘up’ and ‘down’—is a key goal
    in condensed-matter physics and materials science because it can be used to stabilize
    states that are of fundamental interest and also have potential practical applications.
    Examples include improved ferroelectrics for memory devices and materials that
    host Majorana zero modes for quantum computing1,2. Although inversion symmetry
    is naturally broken in several crystalline environments, such as at surfaces and
    interfaces, maximizing the influence of this effect on the electronic states of
    interest remains a challenge. Here we present a mechanism for realizing a much
    larger coupling of inversion-symmetry breaking to itinerant surface electrons
    than is typically achieved. The key element is a pronounced asymmetry of surface
    hopping energies—that is, a kinetic-energy-coupled inversion-symmetry breaking,
    the energy scale of which is a substantial fraction of the bandwidth. Using spin-
    and angle-resolved photoemission spectroscopy, we demonstrate that such a strong
    inversion-symmetry breaking, when combined with spin–orbit interactions, can mediate
    Rashba-like3,4 spin splittings that are much larger than would typically be expected.
    The energy scale of the inversion-symmetry breaking that we achieve is so large
    that the spin splitting in the CoO2- and RhO2-derived surface states of delafossite
    oxides becomes controlled by the full atomic spin–orbit coupling of the 3d and
    4d transition metals, resulting in some of the largest known Rashba-like3,4 spin
    splittings. The core structural building blocks that facilitate the bandwidth-scaled
    inversion-symmetry breaking are common to numerous materials. Our findings therefore
    provide opportunities for creating spin-textured states and suggest routes to
    interfacial control of inversion-symmetry breaking in designer heterostructures
    of oxides and other material classes.

  text: We report growth of single crystals of the nonmagnetic metallic delafossite
    PdRhO2, comparing the results from three different methods. Complete crystallographic
    data were obtained from single crystal X-ray diffraction, and electronic structure
    calculations were made using the refined structural parameters. Focused-ion beam
    microstructuring was used to prepare a sample for measurements of the in- and
    out-of-plane electrical resistivity, and the large observed anisotropy is qualitatively
    consistent with the cylindrical Fermi surface predicted by the calculations.

  text: The complex behaviors underlying reward seeking and consumption are integral
    to organism survival. The hypothalamus and mesolimbic dopamine system are key
    mediators of these behaviors, yet regulation of appetitive and consummatory behaviors
    outside of these regions is poorly understood. The central nucleus of the amygdala
    (CeA) has been implicated in feeding and reward, but the neurons and circuit mechanisms
    that positively regulate these behaviors remain unclear. Here, we defined the
    neuronal mechanisms by which CeA neurons promote food consumption. Using in vivo
    activity manipulations and Ca2+ imaging in mice, we found that GABAergic serotonin
    receptor 2a (Htr2a)-expressing CeA neurons modulate food consumption, promote
    positive reinforcement and are active in vivo during eating. We demonstrated electrophysiologically,
    anatomically and behaviorally that intra-CeA and long-range circuit mechanisms
    underlie these behaviors. Finally, we showed that CeAHtr2a neurons receive inputs
    from feeding-relevant brain regions. Our results illustrate how defined CeA neural
    circuits positively regulate food consumption.

  text: Biofilm formation is critical for the infection cycle of Vibrio cholerae.
    Vibrio exopolysaccharides (VPS) and the matrix proteins RbmA, Bap1 and RbmC are
    required for the development of biofilm architecture. We demonstrate that RbmA
    binds VPS directly and uses a binary structural switch within its first fibronectin
    type III (FnIII-1) domain to control RbmA structural dynamics and the formation
    of VPS-dependent higher-order structures. The structural switch in FnIII-1 regulates
    interactions in trans with the FnIII-2 domain, leading to open (monomeric) or
    closed (dimeric) interfaces. The ability of RbmA to switch between open and closed
    states is important for V. cholerae biofilm formation, as RbmA variants with switches
    that are locked in either of the two states lead to biofilms with altered architecture
    and structural integrity.

  text: The C-terminal transactivation domain (TAD) of BMAL1 (brain and muscle ARNT-like
    1) is a regulatory hub for transcriptional coactivators and repressors that compete
    for binding and, consequently, contributes to period determination of the mammalian
    circadian clock. Here, we report the discovery of two distinct conformational
    states that slowly exchange within the dynamic TAD to control timing. This binary
    switch results from cis/trans isomerization about a highly conserved Trp-Pro imide
    bond in a region of the TAD that is required for normal circadian timekeeping.
    Both cis and trans isomers interact with transcriptional regulators, suggesting
    that isomerization could serve a role in assembling regulatory complexes in vivo.
    Toward this end, we show that locking the switch into the trans isomer leads to
    shortened circadian periods. Furthermore, isomerization is regulated by the cyclophilin
    family of peptidyl-prolyl isomerases, highlighting the potential for regulation
    of BMAL1 protein dynamics in period determination.

  text: Circadian clocks are ubiquitous timing systems that induce rhythms of biological
    activities in synchrony with night and day. In cyanobacteria, timing is generated
    by a posttranslational clock consisting of KaiA, KaiB, and KaiC proteins and a
    set of output signaling proteins, SasA and CikA, which transduce this rhythm to
    control gene expression. Here, we describe crystal and nuclear magnetic resonance
    structures of KaiB-KaiC,KaiA-KaiB-KaiC, and CikA-KaiB complexes. They reveal how
    the metamorphic properties of KaiB, a protein that adopts two distinct folds,
    and the post–adenosine triphosphate hydrolysis state of KaiC create a hub around
    which nighttime signaling events revolve, including inactivation of KaiA and reciprocal
    regulation of the mutually antagonistic signaling proteins, SasA and CikA.

  text: The basic helix–loop–helix PAS domain (bHLH-PAS) transcription factor CLOCK:BMAL1
    (brain and muscle Arnt-like protein 1) sits at the core of the mammalian circadian
    transcription/translation feedback loop. Precise control of CLOCK:BMAL1 activity
    by coactivators and repressors establishes the ∼24-h periodicity of gene expression.
    Formation of a repressive complex, defined by the core clock proteins cryptochrome
    1 (CRY1):CLOCK:BMAL1, plays an important role controlling the switch from repression
    to activation each day. Here we show that CRY1 binds directly to the PAS domain
    core of CLOCK:BMAL1, driven primarily by interaction with the CLOCK PAS-B domain.
    Integrative modeling and solution X-ray scattering studies unambiguously position
    a key loop of the CLOCK PAS-B domain in the secondary pocket of CRY1, analogous
    to the antenna chromophore-binding pocket of photolyase. CRY1 docks onto the transcription
    factor alongside the PAS domains, extending above the DNA-binding bHLH domain.
    Single point mutations at the interface on either CRY1 or CLOCK disrupt formation
    of the ternary complex, highlighting the importance of this interface for direct
    regulation of CLOCK:BMAL1 activity by CRY1.

  text: 'Cryptochromes are evolutionarily related to the light‐dependent DNA repair
    enzyme photolyase, serving as major regulators of circadian rhythms in insects
    and vertebrate animals. There are two types of cryptochromes in the animal kingdom:
    <jats:italic>Drosophila</jats:italic>‐like CRYs that act as nonvisual photopigments
    linking circadian rhythms to the environmental light/dark cycle, and vertebrate‐like
    CRYs that do not appear to sense light directly, but control the generation of
    circadian rhythms by acting as transcriptional repressors. Some animals have both
    types of CRYs, while others possess only one. Cryptochromes have two domains,
    the photolyase homology region (PHR) and an extended, intrinsically disordered
    C‐terminus. While all animal CRYs share a high degree of sequence and structural
    homology in their PHR domains, the C‐termini are divergent in both length and
    sequence identity. Recently, cryptochrome function has been shown to extend beyond
    its pivotal role in circadian clocks, participating in regulation of the DNA damage
    response, cancer progression and glucocorticoid signaling, as well as being implicated
    as possible magnetoreceptors. In this review, we provide a historical perspective
    on the discovery of animal cryptochromes, examine similarities and differences
    of the two types of animal cryptochromes and explore some of the divergent roles
    for this class of proteins.'

  text: Using images from the Hubble Space Telescope Advanced Camera for Surveys,
    we measure the rate of cooling of white dwarfs in the globular cluster 47 Tucanae
    and compare it to modelled cooling curves. We examine the effects of the outer
    convective envelope reaching the nearly isothermal degenerate core and the release
    of latent heat during core crystallization on the white dwarf cooling rates. For
    white dwarfs typical of 47 Tuc, the onset of these effects occur at similar times.
    The latent heat released during crystallization is a small heat source. In contrast,
    the heat reservoir of the degenerate core is substantially larger. When the convective
    envelope reaches the nearly isothermal interior of the white dwarf, the star becomes
    brighter than it would be in the absence of this effect. Our modelled cooling
    curves that include this convective coupling closely match the observed luminosity
    function of the white dwarfs in 47 Tuc.

  text: "Multi-epoch observations with the Advanced Camera Survey and WFC3 on the
    Hubble Space Telescope provide a unique and comprehensive probe of stellar dynamics
    within 47 Tucanae. We confront analytic models of the globular cluster with the
    observed stellar proper motions that probe along the main sequence from just above
    0.8–0.1M⊙ as well as white dwarfs younger than 1 Gyr. One field lies just beyond
    the half-light radius where dynamical models (e.g., lowered Maxwellian distributions)
    make robust predictions for the stellar proper motions. The observed proper motions
    in this outer field show evidence for anisotropy in the velocity distribution
    as well as skewness; the latter is evidence of rotation. The measured velocity
    dispersions and surface brightness distributions agree in detail with a rotating
    anisotropic model of the stellar distribution function with mild dependence of
    the proper-motion dispersion on mass. However, the best-fitting models underpredict
    the rotation and skewness of the stellar velocities. In the second field, centered
    on the core of the cluster, the mass segregation in proper motion is much stronger.
    Nevertheless the model developed in the outer field can be extended inward by
    taking this mass segregation into account in a heuristic fashion. The proper motions
    of the main-sequence stars yield a mass estimate of the cluster of \r\n at a distance
    of 4.7 kpc. By comparing the proper motions of a sample of giant and subgiant
    stars with the observed radial velocities we estimate the distance to the cluster
    kinematically to be 4.29 ± 0.47 kpc."

  text: We present a model to account for the observed debris discs around young white
    dwarfs and the presence of metal lines in their spectra. Stellar evolution models
    predict that the mass-loss on the AGB will be pulsed; furthermore, observations
    indicate that the bulk of the mass-loss occurs on the AGB. In this case, if the
    progenitors of the white dwarfs had remnants of planetary formation like the Sun’s
    Oort cloud or the Kuiper Belt and a planet lying within that cloud or nearby,
    we find that up to 2 per cent of the planetesimals will fall either into planet-crossing
    orbits or into chaotic regions after the mass-loss, depending on the location
    and mass of the planet (from Mars to Neptune). This yields a sufficient mass of
    comets that can be scattered towards the star, form a debris disc and pollute
    the atmosphere.

  text: High-energy (>250 keV) emission has been detected persisting for several tens
    of seconds after the initial spike of magnetar giant flares (GFs). It has been
    conjectured that this emission might arise via inverse Compton scattering in a
    highly extended corona generated by super-Eddington outflows high up in the magnetosphere.
    In this paper, we undertake a detailed examination of this model. We investigate
    the properties of the required scatterers, and whether the mechanism is consistent
    with the degree of pulsed emission observed in the tail of the GF. We conclude
    that the mechanism is consistent with current data, although the origin of the
    scattering population remains an open question. We propose an alternative picture
    in which the emission is closer to that star and is dominated by synchrotron radiation.
    The Reuven Ramaty High Energy Solar Spectroscopic Imager observations of the 2004
    December flare modestly favour this latter picture. We assess the prospects for
    the Fermi Gamma-ray Space Telescope to detect and characterize a similar high-energy
    component in a future GF. Such a detection should help to resolve some of the
    outstanding issues.
