text: Machine learning interatomic potentials are revolutionizing large-scale, accurate
atomistic modeling in material science and chemistry. Many potentials use atomic
cluster expansion or equivariant message-passing frameworks. Such frameworks typically
use spherical harmonics as angular basis functions, followed by Clebsch-Gordan
contraction to maintain rotational symmetry. We propose a mathematically equivalent
and simple alternative that performs all operations in the Cartesian coordinates.
This approach provides a complete set of polynormially independent features of
atomic environments while maintaining interaction body orders. Additionally, we
integrate low-dimensional embeddings of various chemical elements, trainable radial
channel coupling, and inter-atomic message passing. The resulting potential, named
Cartesian Atomic Cluster Expansion (CACE), exhibits good accuracy, stability,
and generalizability. We validate its performance in diverse systems, including
bulk water, small molecules, and 25-element high-entropy alloys.

text: An azeotrope is a constant boiling point mixture, and its behavior is important
for fluid separation processes. Predicting azeotropes from atomistic simulations
is difficult due to the complexities and convergence problems of Monte Carlo and
free-energy perturbation techniques. Here, we present a methodology for predicting
the azeotropes of binary mixtures, which computes the compositional dependence
of chemical potentials from molecular dynamics simulations using the S0 method
and employs experimental boiling point and vaporization enthalpy data. Using this
methodology, we reproduce the azeotropes, or lack thereof, in five case studies,
including ethanol/water, ethanol/isooctane, methanol/water, hydrazine/water, and
acetone/chloroform mixtures. We find that it is crucial to use the experimental
boiling point and vaporization enthalpy for reliable azeotrope predictions, as
empirical force fields are not accurate enough for these quantities. Finally,
we use regular solution models to rationalize the azeotropes and reveal that they
tend to form when the mixture components have similar boiling points and strong
interactions.

text: High elevation headwater catchments are complex hydrological systems that
seasonally buffer water and release it in the form of snow and ice melt, modulating
downstream runoff regimes and water availability. In High Mountain Asia (HMA),
where a wide range of climates from semi-arid to monsoonal exist, the importance
of the cryospheric contributions to the water budget varies with the amount and
seasonal distribution of precipitation. Losses due to evapotranspiration and sublimation
are to date largely unquantified components of the water budget in such catchments,
although they can be comparable in magnitude to glacier melt contributions to
streamflow. Here, we simulate the hydrology of three high elevation headwater
catchments in distinct climates in HMA over 10 years using an ecohydrological
model geared towards high-mountain areas including snow and glaciers, forced with
reanalysis data. Our results show that evapotranspiration and sublimation together
are most important at the semi-arid site, Kyzylsu, on the northernmost slopes
of the Pamir mountain range. Here, the evaporative loss amounts to 28% of the
water throughput, which we define as the total water added to, or removed from
the water balance within a year. In comparison, evaporative losses are 19% at
the Central Himalayan site Langtang and 13% at the wettest site, 24 K, on the
Southeastern Tibetan Plateau. At the three sites, respectively, sublimation removes
15%, 13% and 6% of snowfall, while evapotranspiration removes the equivalent of
76%, 28% and 19% of rainfall. In absolute terms, and across a comparable elevation
range, the highest ET flux is 413 mm yr−1 at 24 K, while the highest sublimation
flux is 91 mm yr−1 at Kyzylsu. During warm and dry years, glacier melt was found
to only partially compensate for the annual supply deficit.

text: As their statistical power grows, genome-wide association studies (GWAS) have
identified an increasing number of loci underlying quantitative traits of interest.
These loci are scattered throughout the genome and are individually responsible
only for small fractions of the total heritable trait variance. The recently proposed
omnigenic model provides a conceptual framework to explain these observations
by postulating that numerous distant loci contribute to each complex trait via
effect propagation through intracellular regulatory networks. We formalize this
conceptual framework by proposing the “quantitative omnigenic model” (QOM), a
statistical model that combines prior knowledge of the regulatory network topology
with genomic data. By applying our model to gene expression traits in yeast, we
demonstrate that QOM achieves similar gene expression prediction performance to
traditional GWAS with hundreds of times less parameters, while simultaneously
extracting candidate causal and quantitative chains of effect propagation through
the regulatory network for every individual gene. We estimate the fraction of
heritable trait variance in cis- and in trans-, break the latter down by effect
propagation order, assess the trans- variance not attributable to transcriptional
regulation, and show that QOM correctly accounts for the low-dimensional structure
of gene expression covariance. We furthermore demonstrate the relevance of QOM
for systems biology, by employing it as a statistical test for the quality of
regulatory network reconstructions, and linking it to the propagation of nontranscriptional
(including environmental) effects.

text: Tidal freshwater marshes are threatened by seawater intrusion globally due
to freshwater discharge reduction and sea-level rise. However, terrestrial nitrate
(NO3−) transport responding to seawater intrusion remains poorly understood in
tidal marshes. After validation against laboratory experiments, numerical simulations
were conducted to analyze seawater intrusion effects on terrestrial NO3− transport
and transformation in tidal marsh aquifers. Results reveal that seawater intrusion
noticeably affects NO3− transport from the marsh aquifer to the tidal creek. Seawater
intrusion results in an upper saline plume and a saltwater wedge within the aquifer,
which markedly narrows the discharge outlet width of the NO3− plume and intensifies
the peak NO3− flux across the creek bank. Consequently, both the NO3− removal
efficiency and total nitrogen gas load to the creek decrease substantially after
seawater intrusion. This is because the reduction of the transit time and the
mixing zone width of the NO3− plume after seawater intrusion weakens denitrification.
Sensitivity analyses indicate that the difference of the NO3− removal efficiency
before and after seawater intrusion depends on soil properties. A larger unsaturated
flow effect, saturated hydraulic conductivity or effective porosity leads to a
greater difference of the NO3− removal efficiency before and after seawater intrusion.
The predicted decrease of the NO3− removal efficiency after seawater intrusion
is consistent with existing field data.

text: Wildfires are increasing in frequency, intensity, and extent globally due
to climate change and they can alter forest composition, structure, and function.
The destruction and subsequent regrowth of young vegetation can modify the ecosystem
evapotranspiration and downstream water availability. However, the response of
forest recovery on hydrology is not well known with even the sign of evapotranspiration
and water yield changes following forest fires being uncertain across the globe.
Here, we quantify the effects of forest regrowth after catastrophic wildfires
on evapotranspiration and runoff in the world's tallest angiosperm forest (Eucalyptus
regnans) in Australia. We combine eddy covariance measurements including pre-
and post-fire periods, mechanistic ecohydrological modeling and then extend the
analysis spatially to multiple fires in eucalypt-dominated forests in south-eastern
Australia by utilizing remote sensing. We find a fast recovery of evapotranspiration
which reaches and exceeds pre-fire values within 2 years after the bushfire, a
result confirmed by eddy covariance data, remote sensing, and modeling. Such a
fast evapotranspiration recovery is likely generalizable to tall eucalypt forests
in south-eastern Australia as shown by remote sensing. Once climate variability
is discounted, ecohydrological modeling shows evapotranspiration rates from the
recovering forest which reach peak values of +20% evapotranspiration 3 years post-fire.
As a result, modeled runoff decreases substantially. Contrary to previous research,
we find that the increase in modeled evapotranspiration is largely caused by the
aerodynamic effects of a much shorter forest height leading to higher surface
temperature, higher humidity gradients and therefore increased transpiration.
However, increases in evapotranspiration as well as decreases in runoff caused
by the young forest are constrained by energy and water limitations. Our result
of an increase in evapotranspiration due to aerodynamic warming in a shorter forest
after wildfires could occur in many parts of the world experiencing forest disturbances.

text: Production of thermoelectric materials from solution-processed particles involves
the synthesis of particles, their purification and densification into pelletized
material. Chemical changes that occur during each one of these steps render them
performance determining. Particularly the purification steps, bypassed in conventional
solid-state synthesis, are the cause for large discrepancies among similar solution-processed
materials. In present work, the investigation focuses on a water-based surfactant
free solution synthesis of SnSe, a highly relevant thermoelectric material. We
show and rationalize that the number of leaching steps, purification solvent,
annealing, and annealing atmosphere have significant influence on the Sn : Se
ratio and impurity content in the powder. Such compositional changes that are
undetectable by conventional characterization techniques lead to distinct consolidated
materials with different types and concentration of defects. Additionally, the
profound effect on their transport properties is demonstrated. We emphasize that
understanding the chemistry and identifying key chemical species and their role
throughout the process is paramount for optimizing material performance. Furthermore,
we aim to demonstrate the necessity of comprehensive reporting of these steps
as a standard practice to ensure material reproducibility.

text: 'In recent years, solution processes have gained considerable traction as
a cost-effective and scalable method to produce high-performance thermoelectric
materials. The process entails a series of critical steps: synthesis, purification,
thermal treatments, and consolidation, each playing a pivotal role in determining
performance, stability, and reproducibility. We have noticed a need for more comprehensive
details for each of the described steps in most published works. Recognizing the
significance of detailed synthetic protocols, we describe here the approach used
to synthesize and characterize one of the highest-performing polycrystalline p-type
SnSe. In particular, we report the synthesis of SnSe particles in water and the
subsequent surface treatment with CdSe molecular complexes that yields CdSe-SnSe
nanocomposites upon consolidation. Moreover, the surface treatment inhibits grain
growth through Zenner pinning of secondary phase CdSe nanoparticles and enhances
defect formation at different length scales. The enhanced complexity in the CdSe-SnSe
nanocomposite microstructure with respect to SnSe promotes phonon scattering and
thereby significantly reduces the thermal conductivity. Such surface engineering
provides opportunities in solution processing for introducing and controlling
defects, making it possible to optimize the transport properties and attain a
high thermoelectric figure of merit.'

text: Mountains are important suppliers of freshwater to downstream areas, affecting
large populations in particular in High Mountain Asia (HMA). Yet, the propagation
of water from HMA headwaters to downstream areas is not fully understood, as interactions
in the mountain water cycle between the cryo-, hydro- and biosphere remain elusive.
We review the definition of blue and green water fluxes as liquid water that contributes
to runoff at the outlet of the selected domain (blue) and water lost to the atmosphere
through vapor fluxes, that is evaporation from water, ground, and interception
plus transpiration (green) and propose to add the term white water to account
for the (often neglected) evaporation and sublimation from snow and ice. We provide
an assessment of models that can simulate the cryo-hydro-biosphere continuum and
the interactions between spheres in high mountain catchments, going beyond disciplinary
separations. Land surface models are uniquely able to account for such complexity,
since they solve the coupled fluxes of water, energy, and carbon between the land
surface and atmosphere. Due to the mechanistic nature of such models, specific
variables can be compared systematically to independent remote sensing observations
– providing vital insights into model accuracy and enabling the understanding
of the complex watersheds of HMA. We discuss recent developments in spaceborne
earth observation products that have the potential to support catchment modeling
in high mountain regions. We then present a pilot study application of the mechanistic
land surface model Tethys & Chloris to a glacierized watershed in the Nepalese
Himalayas and discuss the use of high-resolution earth observation data to constrain
the meteorological forcing uncertainty and validate model results. We use these
insights to highlight the remaining challenges and future opportunities that remote
sensing data presents for land surface modeling in HMA.

text: In the class of projective billiards, which contains the usual billiards,
we exhibit counter-examples to Ivrii's conjecture, which states that in any planar
billiard with smooth boundary the set of periodic orbits has zero measure. The
counter-examples are polygons admitting a 2-parameters family of n-periodic orbits,
with n being either 3 or any even integer greater than 4.

text: 'There is an ever-growing zoo of modern neural network models that can efficiently
learn end-to-end control from visual observations. These advanced deep models,
ranging from convolutional to Vision Transformers, from small to gigantic networks,
have been extensively tested on offline image classification tasks. In this paper,
we study these vision models with respect to the open-loop training to closed-loop
generalization abilities, i.e., deployment realizes a causal feedback loop that
is not present during training. This causality gap typically emerges in robotics
applications such as autonomous driving, where a network is trained to imitate
the control commands of a human. In this setting, two situations arise: 1) Closed-loop
testing in-distribution, where the test environment shares properties with those
of offline training data. 2) Closed-loop testing under distribution shifts and
out-of-distribution. Contrary to recently reported results, we show that under
proper training guidelines, all vision architectures perform indistinguishably
well on in-distribution deployment, resolving the causality gap. In situation
2, We observe that scale is the strongest factor in improving closed-loop generalization
regardless of the choice of the model architecture. Our results predict the trend
that in the future we will see larger and larger models being used in offline-training-online-deployment
imitation learning tasks in robotic applications.'

text: Strong data processing inequalities (SDPI) are an important object of study
in Information Theory and have been well studied for f -divergences. Universal
upper and lower bounds have been provided along with several applications, connecting
them to impossibility (converse) results, concentration of measure, hypercontractivity,
and so on. In this paper, we study Renyi divergence and the corresponding SDPI
constant whose behavior seems to deviate from that of ordinary <1>-divergences.
In particular, one can find examples showing that the universal upper bound relating
its SDPI constant to the one of Total Variation does not hold in general. In this
work, we prove, however, that the universal lower bound involving the SDPI constant
of the Chi-square divergence does indeed hold. Furthermore, we also provide a
characterization of the distribution that achieves the supremum when is equal
to 2 and consequently compute the SDPI constant for Renyi divergence of the general
binary channel.

text: We propose a concatenated code construction for a class of discrete-alphabet
oblivious arbitrarily varying channels (AVCs) with cost constraints. The code
has time and space complexity polynomial in the blocklength n . It uses a Reed-Solomon
outer code, logarithmic blocklength random inner codes, and stochastic encoding
by permuting the codeword before transmission. When the channel satisfies a condition
called strong DS-nonsymmetrizability (a modified version of nonsymmetrizability
originally due to Dobrushin and Stambler), we show that the code achieves a rate
that for a variety of oblivious AVCs (such as classically studied error/erasure
channels) match the known capacities.

text: 'Sibson''s α -mutual information has received renewed attention recently in
several contexts: concentration of measure under dependence, statistical learning,
hypothesis testing, and estimation theory. In this work, we introduce several
variational representations of Sibson''s α -mutual information: 1) as a supremum
over joint distributions of (a combination of) KL divergences; and 2) as a supremum
over functions of opportune expected values. Leveraging them, we produce a variety
of novel and known results, including a generalization of transportation-cost
inequalities and Fano''s inequality.'

text: 'Markov chains are the de facto finite-state model for stochastic dynamical
systems, and Markov decision processes (MDPs) extend Markov chains by incorporating
non-deterministic behaviors. Given an MDP and rewards on states, a classical optimization
criterion is the maximal expected total reward where the MDP stops after T steps,
which can be computed by a simple dynamic programming algorithm. We consider a
natural generalization of the problem where the stopping times can be chosen according
to a probability distribution, such that the expected stopping time is T, to optimize
the expected total reward. Quite surprisingly we establish inter-reducibility
of the expected stopping-time problem for Markov chains with the Positivity problem
(which is related to the well-known Skolem problem), for which establishing either
decidability or undecidability would be a major breakthrough. Given the hardness
of the exact problem, we consider the approximate version of the problem: we show
that it can be solved in exponential time for Markov chains and in exponential
space for MDPs.'

text: 'Combinatorial optimization is a challenging problem applicable in a wide
range of fields from logistics to finance. Recently, quantum computing has been
used to attempt to solve these problems using a range of algorithms, including
parameterized quantum circuits, adiabatic protocols, and quantum annealing. These
solutions typically have several challenges: 1) there is little to no performance
gain over classical methods; 2) not all constraints and objectives may be efficiently
encoded in the quantum ansatz; and 3) the solution domain of the objective function
may not be the same as the bit strings of measurement outcomes. This work presents
“nonnative hybrid algorithms”: a framework to overcome these challenges by integrating
quantum and classical resources with a hybrid approach. By designing nonnative
quantum variational anosatzes that inherit some but not all problem structure,
measurement outcomes from the quantum computer can act as a resource to be used
by classical routines to indirectly compute optimal solutions, partially overcoming
the challenges of contemporary quantum optimization approaches. These methods
are demonstrated using a publicly available neutral-atom quantum computer on two
simple problems of Max k-Cut and maximum independent set. We find improvements
in solution quality when comparing the hybrid algorithm to its “no quantum” version,
a demonstration of a “comparative advantage.”'

text: The ascent of water from the soil to the leaves of vascular plants, described
by the study of plant hydraulics, regulates ecosystem responses to environmental
forcing and recovery from stress periods. Several approaches to model plant hydraulics
have been proposed. In this study, we introduce four different versions of plant
hydraulics representations in the terrestrial biosphere model T&C to understand
the significance of plant hydraulics to ecosystem functioning. We tested representations
of plant hydraulics, investigating plant water capacitance, and long-term xylem
damages following drought. The four models we tested were a combination of representations
including or neglecting capacitance and including or neglecting xylem damage legacies.
Using the models at six case studies spanning semiarid to tropical ecosystems,
we quantify how plant xylem flow, plant water storage and long-term xylem damage
can modulate overall water and carbon dynamics across multiple time scales. We
show that as drought develops, models with plant hydraulics predict a slower onset
of plant water stress, and a diurnal variability of water and carbon fluxes closer
to observations. Plant water storage was found to be particularly important for
the diurnal dynamics of water and carbon fluxes, with models that include plant
water capacitance yielding better results. Models including permanent damage to
conducting plant tissues show an additional significant drought legacy effect,
limiting plant productivity during the recovery phase following major droughts.
However, when considering ecosystem responses to the observed climate variability,
plant hydraulic modules alone cannot significantly improve the overall model performance,
even though they reproduce more realistic water and carbon dynamics. This opens
new avenues for model development, explicitly linking plant hydraulics with additional
ecosystem processes, such as plant phenology and improved carbon allocation algorithms.

text: Accurately predicting weather and climate in cities is critical for safeguarding
human health and strengthening urban resilience. Multimodel evaluations can lead
to model improvements; however, there have been no major intercomparisons of urban-focussed
land surface models in over a decade. Here, in Phase 1 of the Urban-PLUMBER project,
we evaluate the ability of 30 land surface models to simulate surface energy fluxes
critical to atmospheric meteorological and air quality simulations. We establish
minimum and upper performance expectations for participating models using simple
information-limited models as benchmarks. Compared with the last major model intercomparison
at the same site, we find broad improvement in the current cohort's predictions
of short-wave radiation, sensible and latent heat fluxes, but little or no improvement
in long-wave radiation and momentum fluxes. Models with a simple urban representation
(e.g., ‘slab’ schemes) generally perform well, particularly when combined with
sophisticated hydrological/vegetation models. Some mid-complexity models (e.g.,
‘canyon’ schemes) also perform well, indicating efforts to integrate vegetation
and hydrology processes have paid dividends. The most complex models that resolve
three-dimensional interactions between buildings in general did not perform as
well as other categories. However, these models also tended to have the simplest
representations of hydrology and vegetation. Models without any urban representation
(i.e., vegetation-only land surface models) performed poorly for latent heat fluxes,
and reasonably for other energy fluxes at this suburban site. Our analysis identified
widespread human errors in initial submissions that substantially affected model
performances. Although significant efforts are applied to correct these errors,
we conclude that human factors are likely to influence results in this (or any)
model intercomparison, particularly where participating scientists have varying
experience and first languages. These initial results are for one suburban site,
and future phases of Urban-PLUMBER will evaluate models across 20 sites in different
urban and regional climate zones.
