text: A cation exchange-based route was used to produce Cu2ZnSnS4 (CZTS)-Ag2S nanoparticles
with controlled composition. We report a detailed study of the formation of such
CZTS-Ag2S nanoheterostructures and of their photocatalytic properties. When compared
to pure CZTS, the use of nanoscale p-n heterostructures as light absorbers for
photocatalytic water splitting provides superior photocurrents. We associate this
experimental fact to a higher separation efficiency of the photogenerated electron-hole
pairs. We believe this and other type-II nanoheterostructures will open the door
to the use of CZTS, with excellent light absorption properties and made of abundant
and environmental friendly elements, to the field of photocatalysis.

text: 'A simple and effective method to introduce precise amounts of doping in nanomaterials
produced from the bottom-up assembly of colloidal nanoparticles (NPs) is described.
The procedure takes advantage of a ligand displacement step to incorporate controlled
concentrations of halide ions while removing carboxylic acids from the NP surface.
Upon consolidation of the NPs into dense pellets, halide ions diffuse within the
crystal structure, doping the anion sublattice and achieving n-type electrical
doping. Through the characterization of the thermoelectric properties of nanocrystalline
PbS, we demonstrate this strategy to be effective to control charge transport
properties on thermoelectric nanomaterials assembled from NP building blocks.
This approach is subsequently extended to PbTexSe1-x@PbS core-shell NPs, where
a significant enhancement of the thermoelectric figure of merit is achieved. '

text: We report the synthesis and photocatalytic and magnetic characterization of
colloidal nanoheterostructures formed by combining a Pt-based magnetic metal alloy
(PtCo, PtNi) with Cu2ZnSnS4 (CZTS). While CZTS is one of the main candidate materials
for solar energy conversion, the introduction of a Pt-based alloy on its surface
strongly influences its chemical and electronic properties, ultimately determining
its functionality. In this regard, up to a 15-fold increase of the photocatalytic
hydrogen evolution activity was obtained with CZTS–PtCo when compared with CZTS.
Furthermore, two times higher hydrogen evolution rates were obtained for CZTS–PtCo
when compared with CZTS–Pt, in spite of the lower precious metal loading of the
former. Besides, the magnetic properties of the PtCo nanoparticles attached to
the CZTS nanocrystals were retained in the heterostructures, which could facilitate
catalyst purification and recovery for its posterior recycling and/or reutilization.

text: 'Monodisperse Pd2Sn nanorods with tuned size and aspect ratio were prepared
by co-reduction of metal salts in the presence of trioctylphosphine, amine, and
chloride ions. Asymmetric Pd2Sn nanostructures were achieved by the selective
desorption of a surfactant mediated by chlorine ions. A preliminary evaluation
of the geometry influence on catalytic properties evidenced Pd2Sn nanorods to

text: We use ultrafast optical spectroscopy to observe binding of charged single-particle
excitations (SE) in the magnetically frustrated Mott insulator Na2IrO3. Above
the antiferromagnetic ordering temperature (TN) the system response is due to
both Hubbard excitons (HE) and their constituent unpaired SE. The SE response
becomes strongly suppressed immediately below TN. We argue that this increase
in binding energy is due to a unique interplay between the frustrated Kitaev and
the weak Heisenberg-type ordering term in the Hamiltonian, mediating an effective
interaction between the spin-singlet SE. This interaction grows with distance
causing the SE to become trapped in the HE, similar to quark confinement inside
hadrons. This binding of charged particles, induced by magnetic ordering, is a
result of a confinement-deconfinement transition of spin excitations. This observation
provides evidence for spin liquid type behavior which is expected in Na2IrO3.

text: We prove that nonlinear Gibbs measures can be obtained from the corresponding
many-body, grand-canonical, quantum Gibbs states, in a mean-field limit where
the temperature T diverges and the interaction strength behaves as 1/T. We proceed
by characterizing the interacting Gibbs state as minimizing a functional counting
the free-energy relatively to the non-interacting case. We then perform an infinite-dimensional
analogue of phase-space semiclassical analysis, using fine properties of the quantum
relative entropy, the link between quantum de Finetti measures and upper/lower
symbols in a coherent state basis, as well as Berezin-Lieb type inequalities.
Our results cover the measure built on the defocusing nonlinear Schrödinger functional
on a finite interval, as well as smoother interactions in dimensions d 2.

text: Dendritic cells are potent antigen-presenting cells endowed with the unique
ability to initiate adaptive immune responses upon inflammation. Inflammatory
processes are often associated with an increased production of serotonin, which
operates by activating specific receptors. However, the functional role of serotonin
receptors in regulation of dendritic cell functions is poorly understood. Here,
we demonstrate that expression of serotonin receptor 5-HT7 (5-HT7TR) as well as
its downstream effector Cdc42 is upregulated in dendritic cells upon maturation.
Although dendritic cell maturation was independent of 5-HT7TR, receptor stimulation
affected dendritic cell morphology through Cdc42-mediated signaling. In addition,
basal activity of 5-HT7TR was required for the proper expression of the chemokine
receptor CCR7, which is a key factor that controls dendritic cell migration. Consistent
with this, we observed that 5-HT7TR enhances chemotactic motility of dendritic
cells in vitro by modulating their directionality and migration velocity. Accordingly,
migration of dendritic cells in murine colon explants was abolished after pharmacological
receptor inhibition. Our results indicate that there is a crucial role for 5-HT7TR-Cdc42-mediated
signaling in the regulation of dendritic cell morphology and motility, suggesting
that 5-HT7TR could be a new target for treatment of a variety of inflammatory
and immune disorders.

text: We consider two-player games played on weighted directed graphs with mean-payoff
and total-payoff objectives, two classical quantitative objectives. While for
single-dimensional games the complexity and memory bounds for both objectives
coincide, we show that in contrast to multi-dimensional mean-payoff games that
are known to be coNP-complete, multi-dimensional total-payoff games are undecidable.
We introduce conservative approximations of these objectives, where the payoff
is considered over a local finite window sliding along a play, instead of the
whole play. For single dimension, we show that (i) if the window size is polynomial,
deciding the winner takes polynomial time, and (ii) the existence of a bounded
window can be decided in NP ∩ coNP, and is at least as hard as solving mean-payoff
games. For multiple dimensions, we show that (i) the problem with fixed window
size is EXPTIME-complete, and (ii) there is no primitive-recursive algorithm to
decide the existence of a bounded window.

text: 'We consider concurrent games played by two players on a finite-state graph,
where in every round the players simultaneously choose a move, and the current
state along with the joint moves determine the successor state. We study the most
fundamental objective for concurrent games, namely, mean-payoff or limit-average
objective, where a reward is associated to each transition, and the goal of player
1 is to maximize the long-run average of the rewards, and the objective of player
2 is strictly the opposite (i.e., the games are zero-sum). The path constraint
for player 1 could be qualitative, i.e., the mean-payoff is the maximal reward,
or arbitrarily close to it; or quantitative, i.e., a given threshold between the
minimal and maximal reward. We consider the computation of the almost-sure (resp.
positive) winning sets, where player 1 can ensure that the path constraint is
satisfied with probability 1 (resp. positive probability). Almost-sure winning
with qualitative constraint exactly corresponds to the question of whether there
exists a strategy to ensure that the payoff is the maximal reward of the game.
Our main results for qualitative path constraints are as follows: (1) we establish
qualitative determinacy results that show that for every state either player 1
has a strategy to ensure almost-sure (resp. positive) winning against all player-2
strategies, or player 2 has a spoiling strategy to falsify almost-sure (resp.
positive) winning against all player-1 strategies; (2) we present optimal strategy
complexity results that precisely characterize the classes of strategies required
for almost-sure and positive winning for both players; and (3) we present quadratic
time algorithms to compute the almost-sure and the positive winning sets, matching
the best known bound of the algorithms for much simpler problems (such as reachability
objectives). For quantitative constraints we show that a polynomial time solution
for the almost-sure or the positive winning set would imply a solution to a long-standing
open problem (of solving the value problem of turn-based deterministic mean-payoff
games) that is not known to be solvable in polynomial time.'

text: Ethylene is a gaseous phytohormone that plays vital roles in plant growth
and development. Previous studies uncovered EIN2 as an essential signal transducer
linking ethylene perception on ER to transcriptional regulation in the nucleus
through a “cleave and shuttle” model. In this study, we report another mechanism
of EIN2-mediated ethylene signaling, whereby EIN2 imposes the translational repression
of EBF1 and EBF2 mRNA. We find that the EBF1/2 3′ UTRs mediate EIN2-directed translational
repression and identify multiple poly-uridylates (PolyU) motifs as functional
cis elements of 3′ UTRs. Furthermore, we demonstrate that ethylene induces EIN2
to associate with 3′ UTRs and target EBF1/2 mRNA to cytoplasmic processing-body
(P-body) through interacting with multiple P-body factors, including EIN5 and
PABs. Our study illustrates translational regulation as a key step in ethylene
signaling and presents mRNA 3′ UTR functioning as a “signal transducer” to sense
and relay cellular signaling in plants.

text: We investigate the performance of five glacier melt models over a multi-decadal
period in order to assess their ability to model future glacier response. The
models range from a simple degree-day model, based solely on air temperature,
to more-sophisticated models, including the full shortwave radiation balance.
In addition to the empirical models, the performance of a physically based energy-balance
(EB) model is examined. The melt models are coupled to an accumulation and a surface
evolution model and applied in a distributed manner to Rhonegletscher, Switzerland,
over the period 1929–2012 at hourly resolution. For calibration, seasonal mass-balance
measurements (2006–12) are used. Decadal ice volume changes for six periods in
the years 1929–2012 serve for model validation. Over the period 2006–12, there
are almost no differences in performance between the models, except for EB, which
is less consistent with observations, likely due to lack of meteorological in
situ data. However, simulations over the long term (1929–2012) reveal that models
which include a separate term for shortwave radiation agree best with the observed
ice volume changes, indicating that their melt relationships are robust in time
and thus suitable for long-term modelling, in contrast to more empirical approaches
that are oversensitive to temperature fluctuations.

text: 'Glaciers in the Andes of Chile seem to be shrinking and possibly loosing
mass, but the number and types of studies conducted, constrained mainly by data
availability, are not sufficient to provide a synopsis of glacier changes for
the past or future or explain in an explicit way causes of the observed changes.
In this paper, we provide a systematic review of changes in glaciers for the entire
country, followed by a discussion of the studies that have provided evidence of
such changes. We identify a missing type of work in distributed, physically-oriented
modelling studies that are needed to bridge the gap between the numerous remote
sensing studies and the specific, point scale works focused on process understanding.
We use an advanced mass balance model applied to one of the best monitored glaciers
in the region to investigate four main research issues that should be addressed
in modelling studies for a sound assessment of glacier changes: 1) the use of
physically-based models of glacier ablation (energy balance models) versus more
empirical models (enhanced temperature index approaches); 2) the importance of
the correct extrapolation of air temperature forcing on glaciers and in high elevation
areas and the large uncertainty in model outputs associated with it; 3) the role
played by snow gravitational redistribution; and 4) the uncertainty associated
with future climate scenarios. We quantify differences in model outputs associated
with each of these choices, and conclude with suggestions for future work directions.'

text: 'Switzerland is one of the countries with some of the longest and best glaciological
data sets. Its glaciers and their changes in response to climate have been extensively
investigated, and the number and quality of related studies are notable. However,
a comprehensive review of glacier changes and their impact on the hydrology of
glacierised catchments for Switzerland is missing and we use the opportunity provided
by the EU-FP7 ACQWA project to review the current state of knowledge about past
changes and future projections. We examine the type of models that have been applied
to infer glacier evolution and identify knowledge gaps that should be addressed
in future research in addition to those indicated in previous publications. Common
characteristics in long-term series of projected future glacier runoff are an
initial peak followed by a decline, associated with shifts in seasonality, earlier
melt onset and reduced summer runoff. However, the quantitative predictions are
difficult to compare, as studies differ in terms of model structure, calibration
strategies, input data, temporal and spatial resolution as well as future scenarios
used for impact studies. We identify two sources of uncertainties among those
emerging from recent research, and use simulations over four glaciers to: i) quantify
the importance of the correct extrapolation of air temperature, and ii) point
at the key role played by debris cover in modulating glacier response.'

text: Himalayan glacier tongues are commonly debris covered and they are an important
source of melt water. However, they remain relatively unstudied because of the
inaccessibility of the terrain and the difficulties in field work caused by the
thick debris mantles. Observations of debris-covered glaciers are therefore scarce
and airborne remote sensing may bridge the gap between scarce field observations
and coarse resolution space-borne remote sensing. In this study we deploy an Unmanned
Aerial Vehicle (UAV) before and after the melt and monsoon season (May and October
2013) over the debris-covered tongue of the Lirung Glacier in Nepal. Based on
stereo-imaging and the structure for motion algorithm we derive highly detailed
ortho-mosaics and digital elevation models (DEMs), which we geometrically correct
using differential GPS observations collected in the field. Based on DEM differencing
and manual feature tracking we derive the mass loss and the surface velocity of
the glacier at a high spatial accuracy. On average, mass loss is limited and the
surface velocity is very small. However, the spatial variability of melt rates
is very high, and ice cliffs and supra-glacial ponds show mass losses that can
be an order of magnitude higher than the average. We suggest that future research
should focus on the interaction between supra-glacial ponds, ice cliffs and englacial
hydrology to further understand the dynamics of debris-covered glaciers. Finally,
we conclude that UAV deployment has large potential in glaciology and it may revolutionize
methods currently applied in studying glacier surface features.

text: The performance of glaciohydrological models which simulate catchment response
to climate variability depends to a large degree on the data used to force the
models. The forcing data become increasingly important in high-elevation, glacierized
catchments where the interplay between extreme topography, climate, and the cryosphere
is complex. It is challenging to generate a reliable forcing data set that captures
this spatial heterogeneity. In this paper, we analyze the results of a 1 year
field campaign focusing on air temperature and precipitation observations in the
Langtang valley in the Nepalese Himalayas. We use the observed time series to
characterize both temperature lapse rates (LRs) and precipitation gradients (PGs).
We study their spatial and temporal variability, and we attempt to identify possible
controlling factors. We show that very clear LRs exist in the valley and that
there are strong seasonal differences related to the water vapor content in the
atmosphere. Results also show that the LRs are generally shallower than the commonly
used environmental lapse rates. The analysis of the precipitation observations
reveals that there is great variability in precipitation over short horizontal
distances. A uniform valley wide PG cannot be established, and several scale-dependent
mechanisms may explain our observations. We complete our analysis by showing the
impact of the observed LRs and PGs on the outputs of the TOPKAPI-ETH glaciohydrological
model. We conclude that LRs and PGs have a very large impact on the water balance
composition and that short-term monitoring campaigns have the potential to improve
model quality considerably.

text: We show that weak solutions of the Derrida-Lebowitz-Speer-Spohn (DLSS) equation
display infinite speed of support propagation. We apply our method to the case
of the quantum drift-diffusion equation which augments the DLSS equation with
a drift term and possibly a second-order diffusion term. The proof is accomplished
using weighted entropy estimates, Hardy's inequality and a family of singular
weight functions to derive a differential inequality; the differential inequality
shows exponential growth of the weighted entropy, with the growth constant blowing
up very fast as the singularity of the weight becomes sharper. To the best of
our knowledge, this is the first example of a nonnegativity-preserving higher-order
parabolic equation displaying infinite speed of support propagation.

text: We derive upper bounds on the waiting time of solutions to the thin-film equation
in the regime of weak slippage n ∈ [2, 32\11). In particular, we give sufficient
conditions on the initial data for instantaneous forward motion of the free boundary.
For n ∈ (2, 32\11), our estimates are sharp, for n = 2, they are sharp up to a
logarithmic correction term. Note that the case n = 2 corresponds-with a grain
of salt-to the assumption of the Navier slip condition at the fluid-solid interface.
We also obtain results in the regime of strong slippage n ∈ (1,2); however, in
this regime we expect them not to be optimal. Our method is based on weighted
backward entropy estimates, Hardy's inequality and singular weight functions;
we deduce a differential inequality which would enforce blowup of the weighted
entropy if the contact line were to remain stationary for too long.

text: Passive immunotherapy with monoclonal antibodies represents a cornerstone
of human anticancer therapies, but has not been established in veterinary medicine
yet. As the tumor-associated antigen EGFR (ErbB-1) is highly conserved between
humans and dogs, and considering the effectiveness of the anti-EGFR antibody cetuximab
in human clinical oncology, we present here a “caninized” version of this antibody,
can225IgG, for comparative oncology studies. Variable region genes of 225, the
murine precursor of cetuximab, were fused with canine constant heavy gamma and
kappa chain genes, respectively, and transfected into Chinese hamster ovary (CHO)
DUKX-B11 cells. Of note, 480 clones were screened and the best clones were selected
according to productivity and highest specificity in EGFR-coated ELISA. Upon purification
with Protein G, the recombinant cetuximab-like canine IgG was tested for integrity,
correct assembly, and functionality. Specific binding to the surface of EGFR-overexpressing
cells was assessed by flow cytometry and immunofluorescence; moreover, binding
to canine mammary tissue was demonstrated by immunohistochemistry. In cell viability
and proliferation assays, incubation with can225IgG led to significant tumor cell
growth inhibition. Moreover, this antibody mediated significant tumor cell killing
via phagocytosis in vitro. We thus present here, for the first time, the generation
of a canine IgG antibody and its hypothetical structure. On the basis of its cetuximab-like
binding site, on the one hand, and the expression of a 91% homologous EGFR molecule
in canine cancer, on the other hand, this antibody may be a promising research
compound to establish passive immunotherapy in dog patients with cancer.

text: Recombination between double-stranded DNA molecules is a key genetic process
which occurs in a wide variety of organisms. Usually, crossing-over (CO) occurs
during meiosis between genotypes with 98.0-99.9% sequence identity, because within-population
nucleotide diversity only rarely exceeds 2%. However, some species are hypervariable
and it is unclear how CO can occur between genotypes with less than 90% sequence
identity. Here, we study CO in Schizophyllum commune, a hypervariable cosmopolitan
basidiomycete mushroom, a frequently encountered decayer of woody substrates.
We crossed two haploid individuals, from the United States and from Russia, and
obtained genome sequences for their 17 offspring. The average genetic distance
between the parents was 14%, making it possible to study CO at very high resolution.
We found reduced levels of linkage disequilibrium between loci flanking the CO
sites indicating that they are mostly confined to hotspots of recombination. Furthermore,
CO events preferentially occurred in regions under stronger negative selection,
in particular within exons that showed reduced levels of nucleotide diversity.
Apparently, in hypervariable species CO must avoid regions of higher divergence
between the recombining genomes due to limitations imposed by the mismatch repair
system, with regions under strong negative selection providing the opportunity
for recombination. These patterns are opposite to those observed in a number of
less variable species indicating that population genomics of hypervariable species
may reveal novel biological phenomena.
