text: In this Introduction, we outline expectations for when and how the hydrogen
and helium atoms in the universe turned from neutral to ionized, focusing on the
earliest, least well understood stages, and emphasize the most important open
questions. We include a historical summary, and highlight the role of reionization
as one of the few milestones in the evolution of the universe since the Big Bang,
and its status as a unique probe of the beginning stages of structure formation.

text: Ice cliffs have been identified as a reason for higher ablation rates on debris-covered
glaciers than are implied by the insulation effects of the debris. This study
aims to improve our understanding of cliff backwasting, and the role of radiative
fluxes in particular. An energy-balance model is forced with new data gathered
in May and October 2013 on Lirung Glacier, Nepalese Himalaya. Observations show
substantial variability in melt between cliffs, between locations on any cliff
and between seasons. Using a high-resolution digital elevation model we calculate
longwave fluxes incident to the cliff from surrounding terrain and include the
effect of local shading on shortwave radiation. This is an advance over previous
studies, that made simplified assumptions on cliff geometry and radiative fluxes.
Measured melt rates varied between 3.25 and 8.6 cm d−1 in May and 0.18 and 1.34
cm d−1 in October. Model results reproduce the strong variability in space and
time, suggesting considerable differences in radiative fluxes over one cliff.
In October the model fails to reproduce stake readings, probably due to the lack
of a refreezing component. Disregarding local topography can lead to overestimation
of melt at the point scale by up to ∼9%.

text: Spatial evolution of supraglacial debris cover on mountain glaciers is a largely
unmonitored and poorly understood phenomenon that directly affects glacier melt.
Supraglacial debris cover for 93 glaciers in the Karakoram, northern Pakistan,
was mapped from Landsat imagery acquired in 1977, 1998, 2009 and 2014. Surge-type
glaciers occupy 41% of the study area and were considered separately. The time
series of debris-covered surface area change shows a mean value of zero or near-zero
change for both surging and non-surging glaciers. An increase in debris-covered
area is often associated with negative regional mass balances. We extend this
logic to suggest that the stable regional mass balances in the Karakoram explain
the zero or near-zero change in debris-covered area. This coupling of trends combined
with our 37 year time series of data suggests the Karakoram anomaly extends further
back in time than previously known.

text: Thick debris cover on glaciers can significantly reduce ice melt. However,
several studies have suggested that debris-covered glaciers in the Himalaya might
have lost mass at a rate similar to debris-free glaciers. We reconstruct elevation
and mass changes for the debris-covered glaciers of the upper Langtang valley,
Nepalese Himalaya, using a digital elevation model (DEM) from 1974 stereo Hexagon
satellite data and the 2000 SRTM (Shuttle Radar Topography Mission) DEM. Uncertainties
are high in the accumulation areas, due to data gaps in the SRTM and difficulties
with delineation of the glacier borders. Even with these uncertainties, we obtain
thinning rates comparable to those of several other studies in the Himalaya. In
particular, we obtain a total mass balance for the investigated debris-covered
glaciers of the basin of –0.32 ± 0.18 m w.e. a−1. However,
there are major spatial differences both between glaciers and within any single
glacier, exhibiting a very distinct nonlinear mass-balance profile with elevation.
Through analysis of surface velocities derived from Landsat ETM+ imagery, we show
that thinning occurs in areas of low velocity and low slope. These areas are prone
to a general, dynamic decay of surface features and to the development of supraglacial
lakes and ice cliffs, which may be responsible for a considerable increase in
overall glacier ablation.

text: Meteorological studies in high-mountain environments form the basis of our
understanding of catchment hydrology and glacier accumulation and melt processes,
yet high-altitude (>4000 m above sea level, asl) observatories are rare. This
research presents meteorological data recorded between December 2012 and November
2013 at seven stations in Nepal, ranging in elevation from 3860 to 5360 m asl.
Seasonal and diurnal cycles in air temperature, vapour pressure, incoming short-wave
and long-wave radiation, atmospheric transmissivity, wind speed, and precipitation
are compared between sites. Solar radiation strongly affects diurnal temperature
and vapour pressure cycles, but local topography and valley-scale circulations
alter wind speed and precipitation cycles. The observed diurnal variability in
vertical temperature gradients in all seasons highlights the importance of in
situ measurements for melt modelling. The monsoon signal (progressive onset and
sharp end) is visible in all data-sets, and the passage of the remnants of Typhoon
Phailin in mid-October 2013 provides an interesting case study on the possible
effects of such storms on glaciers in the region.

text: "The hydrology of high-elevation watersheds of the Hindu Kush-Himalaya region
(HKH) is poorly known. The correct representation of internal states and process
dynamics in glacio-hydrological models can often not be verified due to missing
in situ measurements. We use a new set of detailed ground data from the upper
Langtang valley in Nepal to systematically guide a state-of-the art glacio-hydrological
model through a parameter assigning process with the aim to understand the hydrology
of the catchment and contribution of snow and ice processes to runoff. 14 parameters
are directly calculated on the basis of local data, and 13 parameters are calibrated
against 5 different datasets of in situ or remote sensing data. Spatial fields
of debris thickness are reconstructed through a novel approach that employs data
from an Unmanned Aerial Vehicle (UAV), energy balance modeling and statistical
techniques. The model is validated against measured catchment runoff (Nash–Sutcliffe
efficiency 0.87) and modeled snow cover is compared to Landsat snow cover. The
advanced representation of processes allowed assessing the role played by avalanching
for runoff for the first time for a Himalayan catchment (5% of annual water inputs
to the hydrological system are due to snow redistribution) and to quantify the
hydrological significance of sub-debris ice melt (9% of annual water inputs).
Snowmelt is the most important contributor to total runoff during the hydrological
year 2012/2013 (representing 40% of all sources), followed by rainfall (34%) and
ice melt (26%). A sensitivity analysis is used to assess the efficiency of the
monitoring network and identify the timing and location of field measurements
that constrain model uncertainty. The methodology to set up a glacio-hydrological
model in high-elevation regions presented in this study can be regarded as a benchmark
for modelers in the HKH seeking to evaluate their calibration approach, their
experimental setup and thus to reduce the predictive model uncertainty.\r\n\r\n"

text: Air temperature is one of the most relevant input variables for snow and ice
melt calculations. However, local meteorological conditions, complex topography,
and logistical concerns in glacierized regions make the measuring and modeling
of air temperature a difficult task. In this study, we investigate the spatial
distribution of 2 m air temperature over mountain glaciers and propose a modification
to an existing model to improve its representation. Spatially distributed meteorological
data from Haut Glacier d'Arolla (Switzerland), Place (Canada), and Juncal Norte
(Chile) Glaciers are used to examine approximate flow line temperatures during
their respective ablation seasons. During warm conditions (off-glacier temperatures
well above 0°C), observed air temperatures in the upper reaches of Place Glacier
and Haut Glacier d'Arolla decrease down glacier along the approximate flow line.
At Juncal Norte and Haut Glacier d'Arolla, an increase in air temperature is observed
over the glacier tongue. While the temperature behavior over the upper part can
be explained by the cooling effect of the glacier surface, the temperature increase
over the glacier tongue may be caused by several processes induced by the surrounding
warm atmosphere. In order to capture the latter effect, we add an additional term
to the Greuell and Böhm (GB) thermodynamic glacier wind model. For high off-glacier
temperatures, the modified GB model reduces root-mean-square error up to 32% and
provides a new approach for distributing air temperature over mountain glaciers
as a function of off-glacier temperatures and approximate glacier flow lines.

text: In this paper, we develop an energy method to study finite speed of propagation
and waiting time phenomena for the stochastic porous media equation with linear
multiplicative noise in up to three spatial dimensions. Based on a novel iteration
technique and on stochastic counterparts of weighted integral estimates used in
the deterministic setting, we formulate a sufficient criterion on the growth of
initial data which locally guarantees a waiting time phenomenon to occur almost
surely. Up to a logarithmic factor, this criterion coincides with the optimal
criterion known from the deterministic setting. Our technique can be modified
to prove finite speed of propagation as well.

text: We present an algorithm for the derivation of lower bounds on support propagation
for a certain class of nonlinear parabolic equations. We proceed by combining
the ideas in some recent papers by the author with the algorithmic construction
of entropies due to Jüngel and Matthes, reducing the problem to a quantifier elimination
problem. Due to its complexity, the quantifier elimination problem cannot be solved
by present exact algorithms. However, by tackling the quantifier elimination problem
numerically, in the case of the thin-film equation we are able to improve recent
results by the author in the regime of strong slippage n ∈ (1, 2). For certain
second-order doubly nonlinear parabolic equations, we are able to extend the known
lower bounds on free boundary propagation to the case of irregular oscillatory
initial data. Finally, we apply our method to a sixth-order quantum drift-diffusion
equation, resulting in an upper bound on the time which it takes for the support
to reach every point in the domain.

text: 'We derive a posteriori estimates for the modeling error caused by the assumption
of perfect incompressibility in the incompressible Navier-Stokes equation: Real
fluids are never perfectly incompressible but always feature at least some low
amount of compressibility. Thus, their behavior is described by the compressible
Navier-Stokes equation, the pressure being a steep function of the density. We
rigorously estimate the difference between an approximate solution to the incompressible
Navier-Stokes equation and any weak solution to the compressible Navier-Stokes
equation in the sense of Lions (without assuming any additional regularity of
solutions). Heuristics and numerical results suggest that our error estimates
are of optimal order in the case of "well-behaved" flows and divergence-free
approximations of the velocity field. Thus, we expect our estimates to justify
the idealization of fluids as perfectly incompressible also in practical situations.'

text: Understanding the role of electron correlations in strong spin-orbit transition-metal
oxides is key to the realization of numerous exotic phases including spin-orbit–assisted
Mott insulators, correlated topological solids, and prospective new high-temperature
superconductors. To date, most attention has been focused on the 5d iridium-based
oxides. We instead consider the Pt-based delafossite oxide PtCoO2. Our transport
measurements, performed on single-crystal samples etched to well-defined geometries
using focused ion beam techniques, yield a room temperature resistivity of only
2.1 microhm·cm (μΩ-cm), establishing PtCoO2 as the most conductive oxide known.
From angle-resolved photoemission and density functional theory, we show that
the underlying Fermi surface is a single cylinder of nearly hexagonal cross-section,
with very weak dispersion along kz. Despite being predominantly composed of d-orbital
character, the conduction band is remarkably steep, with an average effective
mass of only 1.14me. Moreover, the sharp spectral features observed in photoemission
remain well defined with little additional broadening for more than 500 meV below
EF, pointing to suppressed electron-electron scattering. Together, our findings
establish PtCoO2 as a model nearly-free–electron system in a 5d delafossite transition-metal
oxide.

text: Variation in mitochondrial DNA is often assumed to be neutral and is used
to construct the genealogical relationships among populations and species. However,
if extant variation is the result of episodes of positive selection, these genealogies
may be incorrect, although this information itself may pro-vide biologically and
evolutionary meaningful information. In fact, positive Darwinian selection has
been detected in the mitochondrial-encoded subunits that comprise complex I from
diverse taxa with seemingly dissimilar bioenergetic life histories, but the functional
implications of the selected sites are unknown. Complex I produces roughly 40%
of the proton flux that is used to synthesize ATP from ADP, and a functional model
based on the high-resolution structure of complex I described a unique biomechanical
apparatus for proton translocation. We reported positive selection at sites in
this apparatus during the evolution of Pacific salmon, and it appeared this was
also the case in published reports from other taxa, but a comparison among studies
was difficult because different statistical tests were used to detect selection
and oftentimes, specific sites were not reported. Here we review the literature
of positive selection in mitochondrial genomes, the statistical tests used to
detect selection, and the structural and functional models that are currently
available to study the physiological implications of selection. We then search
for signatures of positive selection among the coding mitochondrial genomes of
237 species with a common set of tests and verify that the ND5 subunit of complex
I is a repeated target of positive Darwinian selection in diverse taxa. We propose
a novel hypothesis to explain the results based on their bioenergetic life histories
and provide a guide for laboratory and field studies to test this hypothesis.

text: "We present a method and a tool for generating succinct representations of
sets of concurrent traces. We focus on trace sets that contain all correct or
all incorrect permutations of events from a given trace. We represent trace sets
as HB-Formulas that are Boolean combinations of happens-before constraints between
events. To generate a representation of incorrect interleavings, our method iteratively
explores interleavings that violate the specification and gathers generalizations
of the discovered interleavings into an HB-Formula; its complement yields a representation
of correct interleavings.\r\n\r\nWe claim that our trace set representations can
drive diverse verification, fault localization, repair, and synthesis techniques
for concurrent programs. We demonstrate this by using our tool in three case studies
involving synchronization synthesis, bug summarization, and abstraction refinement
based verification. In each case study, our initial experimental results have
been promising.\r\n\r\nIn the first case study, we present an algorithm for inferring
missing synchronization from an HB-Formula representing correct interleavings
of a given trace. The algorithm applies rules to rewrite specific patterns in
the HB-Formula into locks, barriers, and wait-notify constructs. In the second
case study, we use an HB-Formula representing incorrect interleavings for bug
summarization. While the HB-Formula itself is a concise counterexample summary,
we present additional inference rules to help identify specific concurrency bugs
such as data races, define-use order violations, and two-stage access bugs. In
the final case study, we present a novel predicate learning procedure that uses
HB-Formulas representing abstract counterexamples to accelerate counterexample-guided
abstraction refinement (CEGAR). In each iteration of the CEGAR loop, the procedure
refines the abstraction to eliminate multiple spurious abstract counterexamples
drawn from the HB-Formula."

text: 'The fitness effects of symbionts on their hosts can be context-dependent,
with usually benign symbionts causing detrimental effects when their hosts are
stressed, or typically parasitic symbionts providing protection towards their
hosts (e.g. against pathogen infection). Here, we studied the novel association
between the invasive garden ant Lasius neglectus and its fungal ectosymbiont Laboulbenia
formicarum for potential costs and benefits. We tested ants with different Laboulbenia
levels for their survival and immunity under resource limitation and exposure
to the obligate killing entomopathogen Metarhizium brunneum. While survival of
L. neglectus workers under starvation was significantly decreased with increasing
Laboulbenia levels, host survival under Metarhizium exposure increased with higher
levels of the ectosymbiont, suggesting a symbiont-mediated anti-pathogen protection,
which seems to be driven mechanistically by both improved sanitary behaviours
and an upregulated immune system. Ants with high Laboulbenia levels showed significantly
longer self-grooming and elevated expression of immune genes relevant for wound
repair and antifungal responses (β-1,3-glucan binding protein, Prophenoloxidase),
compared with ants carrying low Laboulbenia levels. This suggests that the ectosymbiont
Laboulbenia formicarum weakens its ant host by either direct resource exploitation
or the costs of an upregulated behavioural and immunological response, which,
however, provides a prophylactic protection upon later exposure to pathogens. '

text: We prove that the three-state toric homogeneous Markov chain model has Markov
degree two. In algebraic terminology this means, that a certain class of toric

text: 'The monotone secant conjecture posits a rich class of polynomial systems,
all of whose solutions are real. These systems come from the Schubert calculus
on flag manifolds, and the monotone secant conjecture is a compelling generalization
of the Shapiro conjecture for Grassmannians (Theorem of Mukhin, Tarasov, and Varchenko).
We present some theoretical evidence for this conjecture, as well as computational
evidence obtained by 1.9 teraHertz-years of computing, and we discuss some of
the phenomena we observed in our data. '

text: The paper describes a generalized iterative proportional fitting procedure
that can be used for maximum likelihood estimation in a special class of the general
log-linear model. The models in this class, called relational, apply to multivariate
discrete sample spaces that do not necessarily have a Cartesian product structure
and may not contain an overall effect. When applied to the cell probabilities,
the models without the overall effect are curved exponential families and the
values of the sufficient statistics are reproduced by the MLE only up to a constant
of proportionality. The paper shows that Iterative Proportional Fitting, Generalized
Iterative Scaling, and Improved Iterative Scaling fail to work for such models.
The algorithm proposed here is based on iterated Bregman projections. As a by-product,
estimates of the multiplicative parameters are also obtained. An implementation
of the algorithm is available as an R-package.

text: The concepts of faithfulness and strong-faithfulness are important for statistical
learning of graphical models. Graphs are not sufficient for describing the association
structure of a discrete distribution. Hypergraphs representing hierarchical log-linear
models are considered instead, and the concept of parametric (strong-) faithfulness
with respect to a hypergraph is introduced. Strong-faithfulness ensures the existence
of uniformly consistent parameter estimators and enables building uniformly consistent
procedures for a hypergraph search. The strength of association in a discrete
distribution can be quantified with various measures, leading to different concepts
of strong-faithfulness. Lower and upper bounds for the proportions of distributions
that do not satisfy strong-faithfulness are computed for different parameterizations
and measures of association.

text: Small GTP-binding proteins of the Ras superfamily play diverse roles in intracellular
trafficking. Among them, the Rab, Arf, and Rho families function in successive
steps of vesicle transport, in forming vesicles from donor membranes, directing
vesicle trafficking toward target membranes and docking vesicles onto target membranes.
These proteins act as molecular switches that are controlled by a cycle of GTP
binding and hydrolysis regulated by guanine nucleotide exchange factors (GEFs)
and GTPase-activating proteins (GAPs). In this study we explored the role of GAPs
in the regulation of the endocytic pathway using fluorescently labeled yeast mating
pheromone α-factor. Among 25 non-essential GAP mutants, we found that deletion
of the GLO3 gene, encoding Arf-GAP protein, caused defective internalization of
fluorescently labeled α-factor. Quantitative analysis revealed that glo3Δ cells
show defective α-factor binding to the cell surface. Interestingly, Ste2p, the
α-factor receptor, was mis-localized from the plasma membrane to the vacuole in
glo3Δ cells. Domain deletion mutants of Glo3p revealed that a GAP-independent
function, as well as the GAP activity, of Glo3p is important for both α-factor
binding and Ste2p localization at the cell surface. Additionally, we found that
deletion of the GLO3 gene affects the size and number of Arf1p-residing Golgi
compartments and causes a defect in transport from the TGN to the plasma membrane.
Furthermore, we demonstrated that glo3Δ cells were defective in the late endosome-to-TGN
transport pathway, but not in the early endosome-to-TGN transport pathway. These
findings suggest novel roles for Arf-GAP Glo3p in endocytic recycling of cell
surface proteins.
