text: A robust combiner for hash functions takes two candidate implementations and
constructs a hash function which is secure as long as at least one of the candidates
is secure. So far, hash function combiners only aim at preserving a single property
such as collision-resistance or pseudorandomness. However, when hash functions
are used in protocols like TLS they are often required to provide several properties
simultaneously. We therefore put forward the notion of robust multi-property combiners
and elaborate on different definitions for such combiners. We then propose a combiner
that provably preserves (target) collision-resistance, pseudorandomness, and being
a secure message authentication code. This combiner satisfies the strongest notion
we propose, which requires that the combined function satisfies every security
property which is satisfied by at least one of the underlying hash function. If
the underlying hash functions have output length n, the combiner has output length
2 n. This basically matches a known lower bound for black-box combiners for collision-resistance
only, thus the other properties can be achieved without penalizing the length
of the hash values. We then propose a combiner which also preserves the property
of being indifferentiable from a random oracle, slightly increasing the output
length to 2 n+ω(log n). Moreover, we show how to augment our constructions in
order to make them also robust for the one-wayness property, but in this case
require an a priory upper bound on the input length.

text: Adaptation in the retina is thought to optimize the encoding of natural light
signals into sequences of spikes sent to the brain. While adaptive changes in
retinal processing to the variations of the mean luminance level and second-order
stimulus statistics have been documented before, no such measurements have been
performed when higher-order moments of the light distribution change. We therefore
measured the ganglion cell responses in the tiger salamander retina to controlled
changes in the second (contrast), third (skew) and fourth (kurtosis) moments of
the light intensity distribution of spatially uniform temporally independent stimuli.
The skew and kurtosis of the stimuli were chosen to cover the range observed in
natural scenes. We quantified adaptation in ganglion cells by studying linear-nonlinear
models that capture well the retinal encoding properties across all stimuli. We
found that the encoding properties of retinal ganglion cells change only marginally
when higher-order statistics change, compared to the changes observed in response
to the variation in contrast. By analyzing optimal coding in LN-type models, we
showed that neurons can maintain a high information rate without large dynamic
adaptation to changes in skew or kurtosis. This is because, for uncorrelated stimuli,
spatio-temporal summation within the receptive field averages away non-gaussian
aspects of the light intensity distribution.

text: "Bi2S3-xTex bulk nanocomposites with crystal domain sizes in the range from
50 nm to 100 nm were obtained from the reaction of Bi2S3 nanorods with Te powder.
The thermoelectric properties of the obtained nanocomposites were analysed in
the temperature range from 0°C to 300°C. We observed how the thermoelectric properties
of the material improved with the annealing temperature, being a spark plasma
sintering process needed to maintain the material nanostructuration while maximising
its electrical properties. Finally thermoelectric dimensionless figures of merit
ZT up to 0.42 were obtained before any charge carrier concentration optimisation.

text: 'Thermoelectricity is a key technology with the potential to improve the efficiency
of energy conversion processes, which may strongly benefit from advances in the
field of nanotechnology. Nanostructured materials are very appealing for thermoelectric
applications, but the full development of their potential requires precise control
of their properties at the nanoscale. Bottom-up assembly of nanoparticles provides
access to a three-dimensional composition control at the nanoscale not attainable
in any other technology. In particular, colloidal nanoheterostructures are especially
interesting building blocks for the bottom-up production of functional nanomaterials.
In the present work, we use PbTe@PbS core-shell nanoparticles as building blocks
for the bottom-up production of PbTe-PbS nanocomposites. We used a ligand exchange
strategy and a hot press process to promote the electrical conductivity of the
nanocomposite and to increase its density. These two approaches allowed us to
improve the performance of bottom-up assembled PbTe-PbS bulk nanostructured materials. '

text: Herein, a colloidal synthetic route to produce highly monodisperse Cu2HgGeSe4
(CHGSe) nanoparticles (NPs) is presented in detail. The high yield of the developed
procedure allowed the production of CHGSe NPs at the gram scale. A thorough analysis
of their structural and optical properties is shown. CHGSe NPs displayed poly-tetrahedral
morphology and narrow size distributions with average size in the range of 10–40
nm and size dispersions below 10 %. A 1.6 eV optical band gap was measured by
mean of UV–Vis. By adjusting the cation ratio, an effective control of their electrical
conductivity is achieved. The prepared NPs are used as building blocks for the
production of CHGSe bulk nanostructured materials. The thermoelectric properties
of CHGSe nanomaterials are studied in the temperature range from 300 to 730 K.
CHGSe nanomaterials reached electrical conductivities up to 5 × 104 S m−1, Seebeck
coefficients above 100 μV K−1, and thermal conductivities below 1.0 W m−1 K−1
which translated into thermoelectric figures of merit up to 0.34 at 730 K.

text: 'We report on the photocatalytic hydrogen evolution under full-arc light irradiation
of CuIn1-xGaxS2 wurtzite nanocrystals in the presence of SO3 2- and S2- as sacrificial
reagents. We analyzed the hydrogen generation rate as a function of the Ga content
and associated it with the energy band positions. For photocatalytic water splitting,
the CuInS2 bandgap is slightly too low to efficiently overcome the reaction over-potential.
The presence of Ga shifts up the CuInS2 conduction band edge providing a larger
driving force for photogenerated carriers to activate the water splitting reduction
reaction. The larger the Ga content, the more energetically favorable the electron
injection, and thus a more efficient use of the photogenerated carriers is reached.
However, the band gap increase associated with the Ga incorporation reduces the
concentration of photogenerated carriers available for water splitting, and consequently
a lower hydrogen conversion rate is obtained for very high Ga contents. The optimum
Ga concentration was experimentally found at CuIn0.3Ga0.7S2. '

text: Cu2ZnSnS4, based on abundant and environmental friendly elements and with
a direct band gap of 1.5 eV, is a main candidate material for solar energy conversion
through both photovoltaics and photocatalysis. We detail here the synthesis of
quasi-spherical Cu 2ZnSnS4 nanoparticles with unprecedented narrow size distributions.
We further detail their use as seeds to produce CZTS-Au and CZTS-Pt heterostructured
nanoparticles. Such heterostructured nanoparticles are shown to have excellent
photocatalytic properties toward degradation of Rhodamine B and hydrogen generation
by water splitting.

text: 'Near-resonant Raman scattering measurements of zinc sulfide nanoparticles
and thin films have been made and correlated to grain and particle size, respectively,
using a 325 nm wavelength excitation source. The area ratios between the first,
second, and third order peaks of ZnS identified as the T 2(LO) mode decrease with
increasing ZnS grain size. This is an effect attributed to changes in the bandgap
energy from quantum confinement due to the varying grain size between the films/particles,
as noted by a shift in the room temperature photoluminescence emission corresponding
to the free exciton emission energy. While Raman scattering spectroscopy is typically
limited to identification of phases and their crystalline properties, it is possible
to attain more than such straightforward information by calibrating the spectral
features to variations between sets of samples. These results open the possibility
of making a quantitative grain size estimation in ZnS thin films and nanostructures,
as well as in other material systems where ZnS may be expected as a secondary
phase, such as Cu2ZnSnS4. Additionally, more commonly used excitation wavelengths
for Raman scattering, such as 514 and 532 nm, are shown to be of limited use in
characterizing ZnS thin films due to the extremely low Raman scattering efficiency
of ZnS in films with sub-micron thicknesses. '

text: Monodispersed Pt3Sn nanoparticles were prepared through a mild thermal synthesis
in the presence of surfactants. The performance of Pt3Sn for the electrooxidation
of ethanol and adsorbed carbon monoxide (COad) in acid medium was studied by a
combination of electrochemical and insitu spectroscopic methods, namely, infrared
reflection absorption spectroscopy and differential electrochemical mass spectrometry
(DEMS), and the results were compared to those obtained with the use of Pt black.
The formation of the Pt3Sn solid solution promoted the oxidation of COad at less-positive
potentials than those required for Pt black. Also, the electrooxidation of ethanol,
especially at lower potentials, was more favorable with Pt3Sn, as deduced from
the higher faradaic currents recorded during the ethanol oxidation reaction (EOR).
However, the distribution of products as deduced by DEMS analysis suggested that
the formation of C1 products, CO2 inclusive, is less significant on Pt3Sn than
on Pt. In fact, the higher faradaic current recorded with the former catalyst
can be attributed to the greater amounts of acetaldehyde and acetic acid formed.
After the EOR, the surface of both Pt and Pt3Sn remained covered by ethanol adsorbates.
Whereas C2 fragments were the main adsorbates at the surface of Pt3Sn after the
EOR, both C1 and C2 species remained adsorbed at Pt black.

text: An appropriate way of realizing property nanoengineering in complex quaternary
chalcogenide nanocrystals is presented for Cu2Cd xSnSey(CCTSe) polypods. The pivotal
role of the polarity in determining morphology, growth, and the polytypic branching
mechanism is demonstrated. Polarity is considered to be responsible for the formation
of an initial seed that takes the form of a tetrahedron with four cation-polar
facets. Size and shape confinement of the intermediate pentatetrahedral seed is
also attributed to polarity, as their external facets are anion-polar. The final
polypod extensions also branch out as a result of a cation-polarity-driven mechanism.
Aberration-corrected scanning transmission electron microscopy is used to identify
stannite cation ordering, while ab initio studies are used to show the influence
of cation ordering/distortion, stoichiometry, and polytypic structural change
on the electronic band structure.

text: We introduce algorithms for the computation of homology, cohomology, and related
operations on cubical cell complexes, using the technique based on a chain contraction
from the original chain complex to a reduced one that represents its homology.
This work is based on previous results for simplicial complexes, and uses Serre’s
diagonalization for cubical cells. An implementation in C++ of the introduced
algorithms is available at http://www.pawelpilarczyk.com/chaincon/ together with
some examples. The paper is self-contained as much as possible, and is written
at a very elementary level, so that basic knowledge of algebraic topology should
be sufficient to follow it.

text: Invasive alien parasites and pathogens are a growing threat to biodiversity
worldwide, which can contribute to the extinction of endemic species. On the Galápagos
Islands, the invasive parasitic fly Philornis downsi poses a major threat to the
endemic avifauna. Here, we investigated the influence of this parasite on the
breeding success of two Darwin's finch species, the warbler finch (Certhidea olivacea)
and the sympatric small tree finch (Camarhynchus parvulus), on Santa Cruz Island
in 2010 and 2012. While the population of the small tree finch appeared to be
stable, the warbler finch has experienced a dramatic decline in population size
on Santa Cruz Island since 1997. We aimed to identify whether warbler finches
are particularly vulnerable during different stages of the breeding cycle. Contrary
to our prediction, breeding success was lower in the small tree finch than in
the warbler finch. In both species P. downsi had a strong negative impact on breeding
success and our data suggest that heavy rain events also lowered the fledging
success. On the one hand parents might be less efficient in compensating their
chicks' energy loss due to parasitism as they might be less efficient in foraging
on days of heavy rain. On the other hand, intense rainfalls might lead to increased
humidity and more rapid cooling of the nests. In the case of the warbler finch
we found that the control of invasive plant species with herbicides had a significant
additive negative impact on the breeding success. It is very likely that the availability
of insects (i.e. food abundance) is lower in such controlled areas, as herbicide
usage led to the removal of the entire understory. Predation seems to be a minor
factor in brood loss.

text: 'First cycle games (FCG) are played on a finite graph by two players who push
a token along the edges until a vertex is repeated, and a simple cycle is formed.
The winner is determined by some fixed property Y of the sequence of labels of
the edges (or nodes) forming this cycle. These games are traditionally of interest
because of their connection with infinite-duration games such as parity and mean-payoff
games. We study the memory requirements for winning strategies of FCGs and certain
associated infinite duration games. We exhibit a simple FCG that is not memoryless
determined (this corrects a mistake in Memoryless determinacy of parity and mean
payoff games: a simple proof by Bj⋯orklund, Sandberg, Vorobyov (2004) that claims
that FCGs for which Y is closed under cyclic permutations are memoryless determined).
We show that θ (n)! memory (where n is the number of nodes in the graph), which
is always sufficient, may be necessary to win some FCGs. On the other hand, we
identify easy to check conditions on Y (i.e., Y is closed under cyclic permutations,
and both Y and its complement are closed under concatenation) that are sufficient
to ensure that the corresponding FCGs and their associated infinite duration games
are memoryless determined. We demonstrate that many games considered in the literature,
such as mean-payoff, parity, energy, etc., satisfy these conditions. On the complexity
side, we show (for efficiently computable Y) that while solving FCGs is in PSPACE,
solving some families of FCGs is PSPACE-hard. '

text: Energy games belong to a class of turn-based two-player infinite-duration
games played on a weighted directed graph. It is one of the rare and intriguing
combinatorial problems that lie in NP∩co-NP, but are not known to be in P. The
existence of polynomial-time algorithms has been a major open problem for decades
and apart from pseudopolynomial algorithms there is no algorithm that solves any
non-trivial subclass in polynomial time. In this paper, we give several results
based on the weight structures of the graph. First, we identify a notion of penalty
and present a polynomial-time algorithm when the penalty is large. Our algorithm
is the first polynomial-time algorithm on a large class of weighted graphs. It
includes several worst-case instances on which previous algorithms, such as value
iteration and random facet algorithms, require at least sub-exponential time.
Our main technique is developing the first non-trivial approximation algorithm
and showing how to convert it to an exact algorithm. Moreover, we show that in
a practical case in verification where weights are clustered around a constant
number of values, the energy game problem can be solved in polynomial time. We
also show that the problem is still as hard as in general when the clique-width
is bounded or the graph is strongly ergodic, suggesting that restricting the graph
structure does not necessarily help.

text: Transgenerational effects are broader than only parental relationships. Despite
mounting evidence that multigenerational effects alter phenotypic and life-history
traits, our understanding of how they combine to determine fitness is not well
developed because of the added complexity necessary to study them. Here, we derive
a quantitative genetic model of adaptation to an extraordinary new environment
by an additive genetic component, phenotypic plasticity, maternal and grandmaternal
effects. We show how, at equilibrium, negative maternal and negative grandmaternal
effects maximize expected population mean fitness. We define negative transgenerational
effects as those that have a negative effect on trait expression in the subsequent
generation, that is, they slow, or potentially reverse, the expected evolutionary
dynamic. When maternal effects are positive, negative grandmaternal effects are
preferred. As expected under Mendelian inheritance, the grandmaternal effects
have a lower impact on fitness than the maternal effects, but this dual inheritance
model predicts a more complex relationship between maternal and grandmaternal
effects to constrain phenotypic variance and so maximize expected population mean
fitness in the offspring.

text: We use two hydrological models of varying complexity to study the Juncal River
Basin in the Central Andes of Chile with the aim to understand the degree of conceptualization
and the spatial structure that are needed to model present and future streamflows.
We use a conceptual semi-distributed model based on elevation bands [Water Evaluation
and Planning (WEAP)], frequently used for water management, and a physically oriented,
fully distributed model [Topographic Kinematic Wave Approximation and Integration
ETH Zurich (TOPKAPI-ETH)] developed for research purposes mainly. We evaluate
the ability of the two models to reproduce the key hydrological processes in the
basin with emphasis on snow accumulation and melt, streamflow and the relationships
between internal processes. Both models are capable of reproducing observed runoff
and the evolution of Moderate-resolution Imaging Spectroradiometer snow cover
adequately. In spite of WEAP's simple and conceptual approach for modelling snowmelt
and its lack of glacier representation and snow gravitational redistribution as
well as a proper routing algorithm, this model can reproduce historical data with
a similar goodness of fit as the more complex TOPKAPI-ETH. We show that the performance
of both models can be improved by using measured precipitation gradients of higher
temporal resolution. In contrast to the good performance of the conceptual model
for the present climate, however, we demonstrate that the simplifications in WEAP
lead to error compensation, which results in different predictions in simulated
melt and runoff for a potentially warmer future climate. TOPKAPI-ETH, using a
more physical representation of processes, depends less on calibration and thus
is less subject to a compensation of errors through different model components.
Our results show that data obtained locally in ad hoc short-term field campaigns
are needed to complement data extrapolated from long-term records for simulating
changes in the water cycle of high-elevation catchments but that these data can
only be efficiently used by a model applying a spatially distributed physical
representation of hydrological processes.

text: Central Asian water resources largely depend on melt water generated in the
Pamir and Tien Shan mountain ranges. To estimate future water availability in
this region, it is necessary to use climate projections to estimate the future
glacier extent and volume. In this study, we evaluate the impact of uncertainty
in climate change projections on the future glacier extent in the Amu and Syr
Darya river basins. To this end we use the latest climate change projections generated
for the upcoming IPCC report (CMIP5) and, for comparison, projections used in
the fourth IPCC assessment (CMIP3). With these projections we force a regionalized
glacier mass balance model, and estimate changes in the basins' glacier extent
as a function of the glacier size distribution in the basins and projected temperature
and precipitation. This glacier mass balance model is specifically developed for
implementation in large scale hydrological models, where the spatial resolution
does not allow for simulating individual glaciers and data scarcity is an issue.
Although the CMIP5 ensemble results in greater regional warming than the CMIP3
ensemble and the range in projections for temperature as well as precipitation
is wider for the CMIP5 than for the CMIP3, the spread in projections of future
glacier extent in Central Asia is similar for both ensembles. This is because
differences in temperature rise are small during periods of maximum melt (July–September)
while differences in precipitation change are small during the period of maximum
accumulation (October–February). However, the model uncertainty due to parameter
uncertainty is high, and has roughly the same importance as uncertainty in the
climate projections. Uncertainty about the size of the decline in glacier extent
remains large, making estimates of future Central Asian glacier evolution and
downstream water availability uncertain.

text: 'In the headwater catchments of the main Asian rivers, glaciohydrological
models are a useful tool to anticipate impacts of climatic changes. However, the
reliability of their projections strongly depends on the quality and quantity
of data that are available for parameter estimation, model calibration and validation,
as well as on the accuracy of climate change projections. In this study the physically
oriented, glaciohydrological model TOPKAPI-ETH is used to simulate future changes
in snow, glacier, and runoff from the Hunza River Basin in northern Pakistan.
Three key sources of model uncertainty in future runoff projections are compared:
model parameters, climate projections, and natural climate variability. A novel
approach, applicable also to ungauged catchments, is used to determine which model
parameters and model components significantly affect the overall model uncertainty.
We show that the model is capable of reproducing streamflow and glacier mass balances,
but that all analyzed sources of uncertainty significantly affect the reliability
of future projections, and that their effect is variable in time and in space.
The effect of parametric uncertainty often exceeds the impact of climate uncertainty
and natural climate variability, especially in heavily glacierized subcatchments.
The results of the uncertainty analysis allow detailed recommendations on network
design and the timing and location of field measurements, which could efficiently
help to reduce model uncertainty in the future.'
