text: 'Forests under livestock grazing sustain important ecosystem services but
face potential trade-offs between production and ecological integrity. While the
effects of grazing on individual forest attributes are well documented, their
integrated consequences remain poorly understood, particularly in temperate forest
ecosystems. We evaluated the combined influence of livestock grazing intensity
and canopy cover on individual attributes and ecosystem multifunctionality in
native Nothofagus forests of Tierra del Fuego, Argentina. Across eight ranches
spanning two agroecological regions (Ecotone and Mountain Range), we quantified
forest regeneration, understorey richness and biomass, and soil properties, integrating
them into a multifunctionality index. Using generalized linear mixed models, we
found strong context-dependence: in the Mountain Range, higher grazing intensity
reduced seedling and sapling density, organic matter content, coarse woody debris,
and overall multifunctionality. In the Ecotone, these effects of livestock use
intensity were attenuated, and canopy cover diminished sapling density and multifunctionality,
but moderate cover enhanced understorey. Our results extend multifunctionality
research from grazed grasslands to grazed temperate forests and show that ecological
responses and trade-offs vary across landscape units. We conclude that the Mountain
Range is more vulnerable to grazing, requiring stricter management, whereas the
Ecotone retains greater capacity to sustain multifunctionality under controlled
livestock use intensity. These findings underscore the importance of region-specific
silvopastoral strategies that reconcile food production with forest conservation
in southern Patagonia and comparable temperate forest landscapes worldwide.'

text: The oxygen reduction reaction (ORR) remains a critical bottleneck in fuel
cells and metal-air batteries due to the lack of highly efficient electrocatalysts.
Here, we report a simple strategy for synthesizing a palladium-based heterostructured
electrocatalyst supported on a carbon nitride matrix (PdH-Pd@CN), which exhibits
remarkable ORR activity with a half-wave potential of 0.91 V and excellent durability
in 0.1 M KOH. Within the heterostructure, hydrogen intercalation expands the Pd
lattice, while interstitial hydrogen doping facilitates charge transfer from Pd
to H owing to their electronegativity difference. These synergistic effects modulate
the electronic structure, thereby enhancing both activity and stability. When
employed in Zn-air batteries, PdH-Pd@CN delivers a maximum power density of 176
mW cm− (Liu et al., 2025) and capacity of 805 mAh g− (Sun et al., 2021) Zn. These
findings demonstrate the strong potential of PdH-Pd@CN as an efficient ORR electrocatalyst
for next-generation metal-air batteries and related energy technologies.

text: "Little Red Dots (LRDs) are compact sources at z > 5 discovered through James
Webb Space Telescope spectroscopy. Their spectra exhibit broad Balmer emission
lines (>~1000 km s^−1), alongside absorption features and a pronounced Balmer
break – evidence for a dense, neutral hydrogen medium, in which the n = 2 state
is significantly populated. When interpreted as arising\r\nfrom active galactic
nucleus broad-line regions, inferred black hole masses from local scaling relations
exceed expectations given their stellar masses, challenging models of early black
hole–galaxy co-evolution. However, radiative transfer effects in dense media may
also impact the formation of hydrogen emission lines. We model three scattering
processes shaping hydrogen\r\nline profiles: resonance scattering by hydrogen
in the n = 2 state, Raman scattering of ultraviolet (UV) radiation by ground-state
hydrogen, and Thomson scattering by free electrons. Using 3D Monte Carlo radiative
transfer simulations, we examine their imprint on line shapes and ratios. Resonance
scattering produces strong deviations from Case B flux ratios, clear differences\r\nbetween
Hα and Hβ, and encodes gas kinematics in line profiles but cannot broaden Hβ due
to conversion to Paα. While Raman scattering can yield broad wings, scattering
of the UV continuum is disfavoured given the absence of strong full width at half-maximum
variations across transitions. Raman scattering of higher Lyman-series emission
can produce Hα/Hβ wing\r\nwidth ratios of >~1.28, agreeing with observations.
Thomson scattering can reproduce the observed >~ 1000 km s^−1 wings under plausible
conditions – e.g. Te ∼ 10^4 K and Ne ∼ 10^24 cm^−2 – and lead to black hole mass
overestimates by factors 10. Our results provide a framework for interpreting
hydrogen lines in LRDs and similar systems."

text: Cellular plasticity, the ability of a differentiated cell to adopt another
phenotypic identity, is restricted under basal conditions, but can be elicited
upon damage. However, the molecular mechanism enabling such plasticity remains
largely unexplored. Here, we report damage-induced cellular plasticity of secretory
enteroendocrine cells (EEs) in the adult Drosophila midgut. Ionizing radiation
induces EE fate conversion and activates stress-responsive programs in EE lineages,
accompanied by the induction of the stress-inducible transcription factor Xrp1
and the cytokine gene upd3. Xrp1 and upd3 are both necessary for radiation-induced
EE plasticity. Under basal conditions, EE-specific Xrp1 overexpression triggers
ectopic expression of progenitor-specific genes, which is necessary for Xrp1 to
drive EE plasticity. Our work identifies Xrp1 as a crucial regulator that coordinates
damage-induced signaling and transcriptional reprogramming, enabling the reactivation
of cellular plasticity in differentiated cells.

text: Formation during the first cycles of Li-rich layered oxide (LRLO) cathode
materials consolidates the interphase and leads to structural changes that are
decisive for long-term cyclability. However, the nature and effect of the changes
are material-dependent and unknown for the important class of Co-free, Ni-poor
LRLOs. Here, we analyze the processes during the tailored formation procedure
of a typical class member, Li1.28Ni0.15Mn0.57O2, and demonstrate that it remarkably
changes lattice composition and structure as a prerequisite for stable cycling.
We combine electrochemistry, operando mass spectrometry, X-ray diffraction, and
X-ray absorption spectroscopy with density functional theory simulations. Activation
most prominently compresses the layer spacing along the c-axis and increases reversible
structural breathing. The large capacity of ∼250 mAh g–1 originates from the Ni2+/Ni4+
and O2–/O– redox couples. Electron exchange during O-redox is smeared over the
entire anionic sublattice rather than localized on specific oxygen atomic sites.
This redox mechanism is reversible without detrimental oxygen evolution, avoiding
continued degradation common in conventional LRLOs. Sequential Ni- and O-redox
during activation irreversibly distorts the coordination of the redox-inactive
Mn4+ centers. This structural evolution of the MnO6 octahedra appears to enable
the superior electrochemical performance of this LRLO phase. These findings define
an activation pathway for the important class of Co-free, Ni-poor LRLOs, offering
potential guidance for the rational design of high-performance, more sustainable
cathode materials.

text: "It is common for programmers to assemble their programs from a combination
of trusted and untrusted components. In this context, a trusted program component
is said to be robustly safe if it behaves safely when linked against arbitrary
untrusted code. Prior work has shown how various encapsulation mechanisms (in
both high- and low-level languages) can be used to protect code so that it is
robustly safe, but none of the existing work has explored how robust safety can
be achieved in a patently unsafe language like C.\r\nIn this paper, we show how
to bring robust safety to a simple yet representative C-like language we call
Rec. Although Rec (like C) is inherently ”dangerous” and thus not robustly safe,
we can ”save” Rec programs via compilation to Cap, a CHERI-like capability machine.
To formalize the benefits of such a hardening compiler, we develop Reckon, a separation
logic for verifying robust safety of Rec programs. Reckon is not sound under Rec’s
unsafe, C-like semantics, but it is sound when Rec programs are hardened via compilation
and linked against untrusted code running on Cap. As a crucial step in proving
soundness of Reckon, we introduce a novel technique of semantic back-translation,
which we formalize by building on the DimSum framework for multi-language semantics.
All our results are mechanized in the Rocq prover."

text: "Many blockchains such as Ethereum execute all incoming transactions sequentially
significantly limiting the potential throughput. A common approach to scale execution
is parallel execution engines that fully utilize modern multi-core architectures.
Parallel execution is then either done optimistically, by executing transactions
in parallel and detecting conflicts on the fly, or guided, by requiring exhaustive
client transaction hints and scheduling transactions accordingly.\r\n\r\nHowever,
recent studies have shown that the performance of parallel execution engines depends
on the nature of the underlying workload. In fact, in some cases, only a 60% speed-up
compared to sequential execution could be obtained. This is the case, as transactions
that access the same resources must be executed sequentially. For example, if
10% of the transactions in a block access the same resource, the execution cannot
meaningfully scale beyond 10 cores. Therefore, a single popular application can
bottleneck the execution and limit the potential throughput.\r\n\r\nIn this paper,
we introduce Anthemius, a block construction algorithm that optimizes parallel
transaction execution throughput. We evaluate Anthemius exhaustively under a range
of workloads, and show that Anthemius enables the underlying parallel execution
engine to process over twice as many transactions."

text: 'Scalability is a crucial requirement for modern large-scale systems, enabling
elasticity and ensuring responsiveness under varying load. While cloud systems
have achieved scalable architectures, blockchain systems remain constrained by
the need to over-provision validator machines to handle peak load. This leads
to resource inefficiency, poor cost scaling, and limits on performance. To address
these challenges, we introduce Pilotfish, the first scale-out transaction execution
engine for blockchains. Pilotfish enables validators to scale horizontally by
distributing transaction execution across multiple worker machines, allowing elasticity
without compromising consistency or determinism. It integrates seamlessly with
the lazy blockchain architecture, completing the missing piece of execution elasticity.
To achieve this, Pilotfish tackles several key challenges: ensuring scalable and
strongly consistent distributed transactions, handling partial crash recovery
with lightweight replication, and maintaining concurrency with a novel versioned-queue
scheduling algorithm. Our evaluation shows that Pilotfish scales linearly up to
at least eight workers per validator for compute-bound workloads, while maintaining
low latency. By solving scalable execution, Pilotfish brings blockchains closer
to achieving end-to-end elasticity, unlocking new possibilities for efficient
and adaptable blockchain systems.'

text: 'The abundant population of little red dots (LRDs), compact objects with red
UV to optical colors and broad Balmer lines at high redshift, is revealing new
insights into the properties of early active galactic nuclei (AGN). Perhaps the
most surprising features of this population are the presence of Balmer absorption
and ubiquitous strong Balmer breaks. Recent models link these features to an active
supermassive black hole (SMBH) cocooned in very dense gas (NH ∼ 1024 cm−2). We
present a stringent test of such models using VLT/MUSE observations of A2744-45924,
the most luminous LRD known to date (LHα ≈ 1044 erg s−1), located behind the Abell-2744
lensing cluster at z = 4.464 (μ = 1.8). We detect a moderately extended Lyα nebula
(h ≈ 5.7 pkpc), spatially offset from the point-like Hα seen by JWST by ≈1.6 pkpc.
The Lyα emission is narrow (FWHM = 270 ± 15 km s−1), and faint (Lyα = 0.07Hα)
compared to Lyα nebulae typically observed around quasars of similar luminosity.
We detect compact N IV]λ1486 emission, spatially aligned with Hα, and a spatial
shift in the far-UV continuum matching the Lyα offset. We discuss that Hα and
Lyα have distinct physical origins: Hα originates from the AGN, while Lyα is powered
by star formation. In the environment of A2744-45924, we identified four extended
Lyα halos (Δz < 0.02, Δr < 100 pkpc). Their Lyα luminosities match the expectations
based on Hα emission, and show no evidence for radiation from A2744-45924 affecting
its surroundings. The lack of strong, compact, and broad Lyα and the absence of
a luminous extended halo, suggest that the UV AGN light is obscured by dense gas
cloaking the SMBH with a covering factor close to unity.'

text: "In this work, we introduce and study what we believe is an intriguing, and,
to the best of our knowledge, previously unknown connection between two fundamental
areas in computational topology, namely topological data analysis (TDA) and knot
theory. Given a function from a topological space to ℝ, TDA provides tools to
simplify and study the importance of topological features: in particular, the
\U0001D459^\U0001D461ℎ-dimensional persistence diagram encodes the topological
changes (or \U0001D459-homology) in the sublevel set as the function value increases
into a set of points in the plane. Given a continuous one parameter family of
such functions, we can combine the persistence diagrams into an object known as
a vineyard, which tracks the evolution of points in the persistence diagram as
the function changes. If we further restrict that family of functions to be periodic,
we identify the two ends of the vineyard, yielding a closed vineyard. This allows
the study of monodromy, which in this context means that following the family
of functions for a period permutes the set of points in a non-trivial way. Recent
work has studied monodromy in the directional persistent homology transform, demonstrating
some interesting connections between an input shape and monodromy in the persistent
homology transform for 0-dimensional homology embedded in ℝ^2.\r\nIn this work,
given a link and a value \U0001D459, we construct a topological space (based on
the given link) and periodic family of functions on this space (based on the Euclidean
distance function), such that the closed \U0001D459-vineyard contains this link.
This shows that vineyards are topologically as rich as one could possibly hope,
suggesting many future directions of work. Importantly, it has at least two immediate
consequences we explicitly point out:\r\n1.\tMonodromy of any periodicity can
occur in a \U0001D459-vineyard for any \U0001D459. This answers a variant of a
question by Arya and collaborators. To exhibit this as a consequence of our first
main result we also reformulate monodromy in a more geometric way, which may be
of interest in itself.\r\n2.\tTopologically distinguishing closed vineyards is
likely to be difficult (from a complexity theory as well as from a practical perspective)
because of the difficulty of knot and link recognition, which have strong connections
to many NP-hard problems."

text: 'Causal discovery from i.i.d. observational data is known to be generally
ill-posed. We demonstrate that if we have access to the distribution induced by
a structural causal model, and additional data from (in the best case) only two
environments that sufficiently differ in the noise statistics, the unique causal
graph is identifiable. Notably, this is the first result in the literature that
guarantees the entire causal graph recovery with a constant number of environments
and arbitrary nonlinear mechanisms. Our only constraint is the Gaussianity of
the noise terms; however, we propose potential ways to relax this requirement.
Of interest on its own, we expand on the well-known duality between independent
component analysis (ICA) and causal discovery; recent advancements have shown
that nonlinear ICA can be solved from multiple environments, at least as many
as the number of sources: we show that the same can be achieved for causal discovery
while having access to much less auxiliary information.'

text: Quantifying cell morphology is central to understanding cellular regulation,
fate, and heterogeneity, yet conventional image-based analyses often struggle
with diverse or irregular shapes. We present a computational framework that uses
topological data analysis to characterise and compare single-cell morphologies
from fluorescence microscopy. Each cell is represented by its contour together
with the position of its nucleus, from which we construct a filtration based on
a radial distance function and derive a persistence diagram encoding the shape’s
topological evolution. The similarity between two cells is quantified using the
2-Wasserstein distance between their diagrams, yielding a shape distance we call
the PH distance. We apply this method to two representative experimental systems—primary
human mesenchymal stem cells (hMSCs) and HeLa cells—and show that PH distances
enable the detection of outliers in those systems, the identification of sub-populations,
and the quantification of shape heterogeneity. We benchmark PH against three established
contour-based distances (aspect ratio, Fourier descriptors, and elastic shape
analysis) and show that PH offers better separation between cell types and greater
robustness when clustering heterogeneous populations. Together, these results
demonstrate that persistent-homology-based signatures provide a principled and
sensitive approach for analysing cell morphology in settings where traditional
geometric or image-based descriptors are insufficient.

which makes them an ideal clade to study such transitions. We analyzed more than
100 dipteran whole-genome assemblies and identified 4 new lineages that underwent
sex-chromosome turnover (in addition to the 5 previously reported). We find that
the majority of turnovers happened in the group Schizophora, which tend to have
fewer genes on Muller element F (the chromosome homologous to the ancestral insect
X chromosome) than lower dipterans, a factor previously hypothesized to facilitate
turnover. Most derived X chromosomes have higher GC content than autosomes, consistent
with a high prevalence of male achiasmy in Diptera. In addition, an excess of
gene movement out of the X is detected for most of these new X chromosomes, and
many of these moved genes have high testis expression in Drosophila, suggesting
that out-of-X gene movement contributes to the long-term demasculinization of
X chromosomes.

text: We unify the variational hypocoercivity framework established by D. Albritton,
S. Armstrong, J.-C. Mourrat, and M. Novack [2], with the notion of second-order
lifts of reversible diffusion processes, recently introduced by A. Eberle and
the second author [30]. We give an abstract, yet fully constructive, presentation
of the theory, so that it can be applied to a large class of linear kinetic equations.
As this hypocoercivity technique does not twist the reference norm, we can recover
accurate and sharp convergence rates in various models. Among those, adaptive
Langevin dynamics (ALD) is discussed in full detail and we show that for near-quadratic
potentials, with suitable choices of parameters, it is a near-optimal second-order
lift of the overdamped Langevin dynamics. As a further consequence, we observe
that the Generalised Langevin Equation (GLE) is also a second-order lift, as the
standard (kinetic) Langevin dynamics are, of the overdamped Langevin dynamics.
Then, convergence of (GLE) cannot exceed ballistic speed, i.e. the square root
of the rate of the overdamped regime. We illustrate this phenomenon with explicit
computations in a benchmark Gaussian case.

text: "Data structures based on trees and tree traversals are ubiquitous in computer
systems. Many low-level programs, including some implementations of critical systems
like page tables and the web browser DOM, rely on generic tree-traversal functions
that traverse tree nodes in a pre-determined order, applying a client-provided
operation to each visited node. Developing a general approach to specifying and
verifying such traversals is tricky since the client-provided per-node operation
can be stateful and may potentially depend on or modify the structure of the tree
being traversed.\r\nIn this paper, we present a recipe for (semi-)automated verification
of such generic, stateful tree traversals. Our recipe is (a) general: it applies
to a range of tree traversals, in particular, pre-, post- and in-order depth-first
traversals; (b) modular: parts of a traversal’s proof can be reused in verifying
other similar traversals; (c) expressive: using the specification of a tree traversal,
we can verify clients that use the traversal in a variety of different ways; and
(d) automatable: many proof obligations can be discharged automatically.\r\nAt
the heart of our recipe is a novel use of tree zippers to represent a logical
abstraction of the tree traversal state, and zipper transitions as an abstraction
of traversal steps. We realize our recipe in the RefinedC framework in Rocq, which
allows us to verify a number of different tree traversals and their clients written
in C."

text: Three-dimensional (3D) microscopy data is often anisotropic with significantly
lower resolution (up to 8x) along the z axis than along the xy axes. Computationally
generating plausible isotropic resolution from anisotropic imaging data would
benefit the visual analysis of large-scale volumes. This paper proposes niiv,
a self-supervised method for isotropic reconstruction of 3D microscopy data that
can quickly produce images at arbitrary output resolutions. The representation
embeds a learned latent code within a neural field that describes the implicit
higher-resolution isotropic image region. We use an attention-guided latent interpolation
approach, which allows flexible information exchange over a local latent neighborhood.
Under isotropic volume assumptions, we self-supervise this representation on low-/high-resolution
lateral image pairs to reconstruct an isotropic volume from low-resolution axial
images. We evaluate our method on simulated and real anisotropic electron (EM)
and light microscopy (LM) data. Compared to diffusion-based baselines, niiv shows
improved reconstruction quality (+1 dB PSNR) and is over three orders of magnitude
faster (1,000x) to infer. Specifically, niiv reconstructs a 128^3 voxel volume
in 2/10th of a second, renderable at varying (continuous) high resolutions for
display. Our code is available at https://github.com/jakobtroidl/niiv-miccai.

text: 'We consider several problems related to packing forests in graphs. The first
one is to find k edge-disjoint forests in a directed graph G of maximal size such
that the indegree of each vertex in these forests is at most k. We describe a
min-max characterization for this problem and show that it can be solved in almost
linear time for fixed k, extending the algorithm of [Gabow, 1995]. Specifically,
the complexity is O(kδm log n), where n, m are the number of vertices and edges
in G respectively, and δ = max{1, k − kG}, where kG is the edge connectivity of
the graph. Using our solution to this problem, we improve complexities for two
existing applications:(1) k-forest problem: find k forests in an undirected graph
G maximizing the number of edges in their union. We show how to solve this problem
in O(k3 min{kn, m} log2 n + k · MAXFLOW(m, m) log n) time, breaking the Ok(n3/2)
complexity barrier of previously known approaches.(2) Directed edge-connectivity
augmentation problem: find a smallest set of directed edges whose addition to
the given directed graph makes it strongly k-connected. We improve the deterministic
complexity for this problem from O(kδ(m + δn) log n) [Gabow, STOC 1994] to O(kδm
log n). A similar approach with the same complexity also works for the undirected
version of the problem.'

text: 'Protein conformational energy landscapes are shaped not only by intramolecular
interactions but also by their environment. In protein crystals and protein-protein
complexes, intermolecular contacts alter this energy landscape, but the exact
nature of this alteration is difficult to decipher. Understanding how the crystal
lattice affects protein dynamics is crucial for crystallography-based studies
of motion, yet its influence on collective motions remains unclear. Aromatic ring
flips in the hydrophobic core represent sensitive probes of such dynamics. Here,
we compare the kinetics of aromatic ring flips in the protein GB1 in crystals,
in complex with its binding partner IgG, and in solution, combining advanced isotope
labeling with quantitative NMR methods. We show that rings in the core flip nearly
a thousand times less frequently in crystals than in solution. Enhanced-sampling
molecular dynamics simulations, based on a new crystal structure, reproduce these
elevated barriers and reveal how the crystal restrains motions. '

text: We present a general theoretical framework for helical dichroism (HD), establishing
an explicit link between chiral resolution and orbital angular momentum (OAM)
exchange in light–matter interaction. Tracing microscopic mechanisms of the OAM
transfer, we derive rotational selection rules, which establish that HD emerges
only from the spin–orbit coupling of light, even for beams without the far-field
OAM. Our findings refine the conditions for observing HD, provide a tool to re-examine
the outcome of prior experiments, and guide future designs for chiral sensing
with structured light.

text: Vernalization-regulated flowering is vital for wheat yield and geographical
distribution, and the diversity of flowering time genes is essential for the breeding
of climate-resilient varieties. Sugars have long been recognized in regulating
flowering; however, the intrinsic connection between carbohydrate metabolism and
vernalization response remains largely unexplored. Here, we identify a fructose
1,6-bisphosphate aldolase (FBA) encoding gene, HtL1/FBA10, as a modulator of heading
time variation based on a genome-wide association study utilizing wheat core germplasm
collections. Evolutionary analysis shows a decrease in the proportion of haplotype-2
of HtL1, which is linked to delayed flowering, in Chinese and American wheat varieties
compared to landraces. Vernalization reduces HtL1/FBA10 phosphorylation levels
and increases its O-GlcNAcylation, which in turn enhances its enzymatic activity
and facilitates VERNALIZATION 1 (VRN1) transcription by regulating histone acetylation
at the VRN1 locus. Our findings provide mechanistic insights into the interplay
between glucose metabolism and the epigenetic regulation of vernalization in winter
wheat.
