text: The oxidation of biomass-derived compounds such as glucose within electrochemical
cells enables both the energy-efficient production of hydrogen and the generation
of additional added-value chemicals from biomass. However, for this biomass valorization
approach to become commercially viable, selective, cost-effective, and highly
active electrooxidation catalysts need to be developed. In this work, we detail
the synthesis of a nickel (Ni) and zinc (Zn)-based electrocatalyst for the glucose
oxidation reaction (GOR) to formic acid (FoA) via calcination of a Zn-based zeolitic
imidazole framework (ZIF) functionalized with ethylenediamine and doped with Ni.
The structure, morphology, and electrochemical performance of the catalysts towards
the anodic GOR to FoA coupled with the cathodic hydrogen evolution reaction (HER)
are subsequently studied. Chronopotentiometry tests with 0.1 M of glucose show
a conversion of 94 % at 250 mA in only 70 min, with a Faradaic efficiency (FE)
of 91 % toward the production of FoA. Meanwhile, at the cathode, the HER FE is
close to 98 %.

text: Root system integrates multiple environmental cues, chiefly gravity and soil
humidity, to anchor plants in soil and forage for water. While the mechanism of
auxin-mediated root gravitropism is comparably well-understood, the root’s capability
to grow toward moist soil for water uptake and drought avoidance, termed root
hydrotropism, remains largely mysterious. Here, we provide key insights into the
mechanism of hydrotropic growth and assign a role to the master regulator of hydrotropism,
MIZU-KUSSEI 1 (MIZ1). We show that efficient hydrotropism requires the attenuation
of antagonistically acting gravitropism, which is inhibited under drought conditions.
Drought stress interferes with subcellular trafficking and the lateral mobility
of PIN auxin transporters, which are polarly localized at the root cell plasma
membranes. This leads to defects in PIN2 polarity and gravity-induced polarization
of PIN3, ultimately inhibiting gravity-induced auxin redistribution and root bending.
The miz1 mutant is defective in all these regulations, and in support of MIZ1’s
action on PINs, pin mutations rescue the hydrotropic defects in the miz1 mutant.
These observations identify a mechanism for how drought via MIZ1 attenuates gravitropism
to promote root hydrotropism for efficient water foraging under drought conditions.

text: 'From anthropogenic litter carried by ocean currents to plant stems travelling
through the atmosphere, geophysical flows are often seeded with elongated, fibre-like
particles. In this study, we used a large-scale laboratory model of a tidal current
– representative of a widespread class of geophysical flows – to investigate the
tumbling motion of long, slender and floating fibres in the complex turbulence
generated by flow interactions with a tidal inlet. Despite the non-stationary,
non-homogeneous and anisotropic nature of this turbulence, we find that long fibres
statistically rotate at the same frequency as eddies of similar size, a phenomenon
called scale selection, which is known to occur in ideal turbulence. Furthermore,
we report that the signal of the instantaneous transverse velocity difference
between the fibre ends changes significantly from the signal produced by the flow
in the fibre surroundings, although the two are statistically equivalent. These
observations have twofold implications. On the one hand, they confirm the reliability
of using the end-to-end velocity signal of rigid fibres to probe the two-point
transverse statistics of the flow, even under realistic conditions: oceanographers
could exploit this observation to measure transverse velocity differences through
elongated floats in the field, where superdiffusion complicates collecting sufficient
data to probe two-point turbulence statistics at a fixed separation effectively.
On the other hand, by addressing the dynamics of inertial range particles floating
in the coastal zone, these observations are crucial to improving our ability to
predict the fate of meso- and macro-litter, a size class that is currently understudied.'

text: Feigenbaum universality is shown to occur in subcritical shear flows. Our
testing ground is the counter-rotation regime of the Taylor–Couette flow, where
numerical calculations are performed within a small periodic domain. The accurate
computation of up to the seventh period-doubling bifurcation, assisted by a purposely
defined Poincaré section, has enabled us to reproduce the two Feigenbaum universal
constants with unprecedented accuracy in a fluid flow problem. We have further
devised a method to predict the bifurcation diagram up to the accumulation point
of the cascade based on the detailed inspection of just the first few period-doubling
bifurcations. Remarkably, the method is applicable beyond the accumulation point,
with predictions remaining valid, in a statistical sense, for the chaotic dynamics
that follows.

text: "In an era of high-resolution displays, powerful design software, and automated
plotting tools, one would think that scientific figures would be clearer than
ever. Yet, despite numerous editorials, guidelines, and workshops dedicated to
improving figure design, poorly constructed figures remain a persistent issue.
Editors and experienced researchers have repeatedly highlighted key pitfalls such
as cluttered layouts, inconsistent formatting, poor color choices, and misleading
visuals. (1−8) Yet, the aforementioned graphical shortcomings continue to plague
even high-impact journals. Why? The problem is not a lack of technology; it is
a combination of poor design habits, rushed deadlines, and a tendency to treat
figures as mere “data dumps” rather than as essential storytelling tools.\r\nMany
people process information more effectively through visuals, naturally associating
concepts easily when presented graphically. A well-crafted figure serves as a
narrative within the larger story, making complex ideas more accessible. Unfortunately,
visual storytelling often takes a backseat in scientific communication. Scientists
are trained to analyze and interpret data, but many default to software-generated
plots without considering accessibility or how their figures will be perceived
by readers outside their immediate field. Without thoughtful design, figures lose
their power to enhance understanding, ultimately limiting the significance of
the research itself.\r\nIn this editorial, we examine the challenges that, in
our view, hamper scientific figure design and discuss how thoughtful refinements
driven by feedback, iteration, and design principles can enhance clarity and impact
visual communication."

text: The transition to chaos in the subcritical regime of counter-rotating Taylor–Couette
flow is investigated using a minimal periodic domain capable of sustaining coherent
structures. Following a Feigenbaum cascade, the dynamics is found to be remarkably
well approximated by a simple discrete map that admits rigorous proof of its chaotic
nature. The chaotic set that arises for the map features densely distributed periodic
points that are in one-to-one correspondence with unstable periodic orbits (UPOs)
of the Navier–Stokes system. This supports the increasingly accepted view that
UPOs may serve as the backbone of turbulence and, indeed, we demonstrate that
it is possible to reconstruct every statistical property of chaotic fluid flow
from UPOs.

text: 'The phytohormone auxin is a major signal coordinating growth and development
in plants. The variety of its effects arises from its ability to form local auxin
maxima and gradients within tissues, generated through directional cell-to-cell
transport and elaborate metabolic control. These auxin distribution patterns instruct
cells in a context-dependent manner to undergo predefined developmental transitions.
In this Review, we discuss advances in auxin action at the level of homeostasis
and signalling. We highlight key insights into the structural basis of PIN-mediated
intercellular auxin transport and explore two novel non-transcriptional auxin
signalling mechanisms: one involving intracellular Ca2+ transients and another
involving cell-surface auxin perception that mediates global, ultrafast phosphorylation.
Furthermore, we examine emerging evidence indicating the involvement of cyclic
adenosine monophosphate as a second messenger in the transcriptional auxin response.
Together, these recent developments in auxin research have profoundly deepened
our understanding of the complex and diverse activities of auxin in plant growth
and development.'

text: For general large non–Hermitian random matrices X and deterministic normal

of the third and last remaining typical universality class for non–Hermitian random
matrices (for normal deformations), after bulk and sharp edge universalities have
been established in recent years.

text: "Garbling is a fundamental cryptographic primitive, with numerous theoretical
and practical applications. Since the first construction by Yao (FOCS’82, ’86),
a line of work has concerned itself with reducing the communication and computational
complexity of that construction. One of the most efficient garbling schemes presently
is the ‘Half Gates’ scheme by Zahur, Rosulek, and Evans (Eurocrypt’15). Despite
its widespread adoption, the provable security of this scheme has been based on
assumptions whose only instantiations are in idealized models. For example, in
their original paper, Zahur, Rosulek, and Evans showed that hash functions satisfying
a notion called circular correlation robustness (CCR) suffice for this task, and
then proved that CCR secure hash functions can be instantiated in the random permutation
model.\r\nIn this work, we show how to securely instantiate the Half Gates scheme
in the standard model. To this end, we first show how this scheme can be securely
instantiated given a (family of) weak CCR hash function, a notion that we introduce.
Furthermore, we show how a weak CCR hash function can be used to securely instantiate
other efficient garbling schemes, namely the ones by Rosulek and Roy (Crypto’21)
and Heath (Eurocrypt’24). Thus we believe this notion to be of independent interest.\r\nFinally,
we construct such weak CCR hash functions using indistinguishability obfuscation
and one-way functions. The security proof of this construction constitutes our
main technical contribution. While our construction is not practical, it serves

we regard to be particularly important given the recent initiative by NIST to
standardize garbling, and the optimizations in Half Gates being potentially adopted."

text: "Cooperative verification is gaining momentum in recent years. The usual setup
in cooperative verification is that a verifier A is run with some pre-defined
resources, and if it is not able to verify the program, the verification task
is passed to a verifier B together with information learned about the program
by verifier A, then the chain can continue to a verifier C, and so on. This scheme
is static: tools run one after another in a fixed pre-defined order and fixed
parameters and resource limits (the scheme may differ for properties to be analyzed,
though).\r\n\r\nBubaak is a program analysis tool that allows to run multiple
program verifiers in a dynamically changing combination of parallel and sequential
portfolios. Bubaak starts the verification process by invoking an initial set
of tasks; every task, when it is done (e.g., because of hitting a time limit or
finishing its job), rewrites itself into one or more successor tasks. New tasks
can be also spawned upon events generated by other tasks. This all happens dynamically
based on the information gathered by finished and running tasks. During their
execution, tasks that run in parallel can exchange (partial) verification artifacts,
either directly or with Bubaak as an intermediary."

text: Two standard models for probabilistic systems are Markov chains (MCs) and
Markov decision processes (MDPs). Classic objectives for such probabilistic models
for control and planning problems are reachability and stochastic shortest path.
The widely studied algorithmic approach for these problems is the Value Iteration
(VI) algorithm which iteratively applies local updates called Bellman updates.
There are many practical approaches for VI in the literature but they all require
exponentially many Bellman updates for MCs in the worst case. A preprocessing
step is an algorithm that is discrete, graph-theoretical, and requires linear
space. An important open question is whether, after a polynomial-time preprocessing,
VI can be achieved with sub-exponentially many Bellman updates. In this work,
we present a new approach for VI based on guessing values. Our theoretical contributions
are twofold. First, for MCs, we present an almost-linear-time preprocessing algorithm
after which, along with guessing values, VI requires only subexponentially many
Bellman updates. Second, we present an improved analysis of the speed of convergence
of VI for MDPs. Finally, we present a practical algorithm for MDPs based on our
new approach. Experimental results show that our approach provides a considerable
improvement over existing VI-based approaches on several benchmark examples from
the literature.

text: Statistical model checking estimates probabilities and expectations of interest
in probabilistic system models by using random simulations. Its results come with
statistical guarantees. However, many tools use unsound statistical methods that
produce incorrect results more often than they claim. In this paper, we provide
a comprehensive overview of tools and their correctness, as well as of sound methods
available for estimating probabilities from the literature. For expected rewards,
we investigate how to bound the path reward distribution to apply sound statistical
methods for bounded distributions, of which we recommend the Dvoretzky-Kiefer-Wolfowitz
inequality that has not been used in SMC so far. We prove that even reachability
rewards can be bounded in theory, and formalise the concept of limit-PAC procedures
for a practical solution. The modes SMC tool implements our methods and recommendations,
which we use to experimentally confirm our results.

text: The possibility of errors in human-engineered formal verification software,
such as model checkers, poses a serious threat to the purpose of these tools.
An established approach to mitigate this problem are certificates—lightweight,
easy-to-check proofs of the verification results. In this paper, we develop novel
certificates for model checking of Markov decision processes (MDPs) with quantitative
reachability and expected reward properties. Our approach is conceptually simple
and relies almost exclusively on elementary fixed point theory. Our certificates
work for arbitrary finite MDPs and can be readily computed with little overhead
using standard algorithms. We formalize the soundness of our certificates in Isabelle/HOL
and provide a formally verified certificate checker. Moreover, we augment existing
algorithms in the probabilistic model checker Storm with the ability to produce
certificates and demonstrate practical applicability by conducting the first formal
certification of the reference results in the Quantitative Verification Benchmark
Set.

text: We consider the problem of refuting equivalence of probabilistic programs,
i.e., the problem of proving that two probabilistic programs induce different
output distributions. We study this problem in the context of programs with conditioning
(i.e., with observe and score statements), where the output distribution is conditioned
by the event that all the observe statements along a run evaluate to true, and
where the probability densities of different runs may be updated via the score
statements. Building on a recent work on programs without conditioning, we present
a new equivalence refutation method for programs with conditioning. Our method
is based on weighted restarting, a novel transformation of probabilistic programs
with conditioning to the output equivalent probabilistic programs without conditioning
that we introduce in this work. Our method is the first to be both a) fully automated,
and b) providing provably correct answers. We demonstrate the applicability of
our method on a set of programs from the probabilistic inference literature.

text: Snow cover is of key importance for water resources in high mountain Asia
(HMA) and is expected to undergo extensive changes in a warming climate. Past
studies have quantified snow cover changes with satellite products of relatively
low spatial resolution (∼500 m) which are hindered by the steep topography of
this mountain region. We derive snowlines from Sentinel-2 and Landsat 5, 7 and
8 images, which, thanks to their higher spatial resolution, are less sensitive
to the local topography. We calculate the snow line altitude (SLA) and its seasonality
for all glacierized catchments of HMA and link these patterns to climate variables
corrected for topographic biases. As such, the snowline changes provide a clear
proxy for climatic changes. Our results highlight a strong spatial variability
in mean SLA and in its seasonal changes, including across mountain chains and
between the monsoon-dominated and the westerlies-dominated catchments. Over the
period 1999–2019, the western regions of HMA (Pamir, Karakoram, Western Himalaya)
have undergone increased snow coverage, expressed as seasonal SLA decrease, in
spring and summer. This change is opposed to a widespread increase in SLA in autumn
across the region, and especially the southeastern regions of HMA (Nyainqentanglha,
Hengduan Shan, South–East Himalaya). Our results indicate that the diversity of
seasonal snow dynamics across the region is controlled not by temperature or precipitation
directly but by the timing and partitioning of solid precipitation. Decadal snowline
changes (1999–2009 vs 2009–2019) seasonally precede temperature changes, suggesting
that seasonal temperature changes in the Karakoram–Pamir and Eastern Nyainqentanglha
regions may have responded to snow cover changes, rather than driving them.

text: "A verifiable delay function VDF(x, T)->(y, π) maps an input x and time parameter
T to an output y together with an efficiently verifiable proof π certifying that
y was correctly computed. The function runs in T sequential steps, and it should
not be possible to compute y much faster than that. The only known practical VDFs
use sequential squaring in groups of unknown order as the sequential function,
i.e., y = x^2^T. There are two constructions for the proof of exponentiation (PoE)
certifying that y = x^2^T, with Wesolowski (Eurocrypt’19) having very short proofs,
but they are more expensive to compute and the soundness relies on stronger assumptions
than the PoE proposed by Pietrzak (ITCS’19).\r\nA recent application of VDFs by
Arun, Bonneau and Clark (Asiacrypt’22) are short-lived proofs and signatures,
which are proofs and signatures that are only sound for some time t, but after
that can be forged by anyone. For this they rely on “watermarkable VDFs”, where
the proof embeds a prover chosen watermark. To achieve stronger notions of proofs/signatures
with reusable forgeability, they rely on “zero-knowledge VDFs”, where instead
of the output y, one just proves knowledge of this output. The existing proposals
for watermarkable and zero-knowledge VDFs all build on Wesolowski’s PoE, for the
watermarkable VDFs there’s currently no security proof.\r\n\r\nIn this work we
give the first constructions that transform any PoEs in hidden order groups into
watermarkable VDFs and into zkVDFs, solving an open question by Arun et al. Unlike
our watermarkable VDF, the zkVDF (required for reusable forgeability) is not very
practical as the number of group elements in the proof is a security parameter.
To address this, we introduce the notion of zero-knowledge proofs of sequential
work (zkPoSW), a notion that relaxes zkVDFs by not requiring that the output is
unique. We show that zkPoSW are sufficient to construct proofs or signatures with
reusable forgeability, and construct efficient zkPoSW from any PoE, ultimately
achieving short lived proofs and signatures that improve upon Arun et al.’s construction
in several dimensions (faster forging times, arguably weaker assumptions).\r\nA
key idea underlying our constructions is to not directly construct a (watermarked
or zk) proof for y = x^2^T, but instead give a (watermarked or zk) proof for the
more basic statement that \r\nx^l, y^l satisfy x^l = x ^r, y^l = y^r for some
r, together with a normal PoE for y^l = (x^l)^2^T."

text: The transverse thermoelectric (Nernst) effect is a powerful probe for studying
the electronic and structural properties of materials. In this study, we employ
transverse thermoelectric measurements to investigate the ferroelectric distortion
in the topological crystalline insulator (TCI) Pb0.60Sn0.40Te, a compound derived
from PbTe and SnTe, known for their exceptional thermoelectric performance and
distinct ferroelectric properties. By leveraging Nernst measurements, we provide
direct evidence of ferroelectric distortion in this TCI, corroborated by Shubnikov–de
Haas quantum oscillations that confirm the presence of two topologically nontrivial
Fermi pockets. Density functional theory calculations show that these pockets
originate from the L and T points in the Brillouin zone of the distorted structure
within the TCI phase. Raman spectroscopy further identifies a structural phase
transition below 50 K, consistent with the quantum oscillation observations. This
observation is further substantiated by temperature-dependent synchrotron X-ray
pair distribution function analysis and transmission electron microscopy, which
confirm the local off-centering of cations at low temperature. These findings
underscore the potential of transverse thermoelectric measurements in unveiling
ferroelectric distortions and their role in modulating topological quantum states,
opening new directions for research into the synergy between ferroelectricity
and topological phases.
