text: 'Morse decompositions partition the flows in a vector field into equivalent
structures. Given such a decomposition, one can define a further summary of its
flow structure by what is called a connection matrix. These matrices, a generalization
of Morse boundary operators from classical Morse theory, capture the connections
made by the flows among the critical structures—such as attractors, repellers,
and orbits—in a vector field. Recently, in the context of combinatorial dynamics,
an efficient persistence-like algorithm to compute connection matrices has been
proposed in Dey, Lipiński, Mrozek, and Slechta [SIAM J. Appl. Dyn. Syst., 23 (2024),
pp. 81–97]. We show that, actually, the classical persistence algorithm with exhaustive
reduction retrieves connection matrices, both simplifying the algorithm of Dey
et al. and bringing the theory of persistence closer to combinatorial dynamical
systems. We supplement this main result with an observation: the concept of persistence
as defined for scalar fields naturally adapts to Morse decompositions whose Morse
sets are filtered with a Lyapunov function. We conclude by presenting preliminary
experimental results.'

text: During complex vocal interactions, different features of acoustic stimuli
are integrated to produce appropriate vocal responses,1 such as copying sounds
during vocal matching behavior in some animals.2,3,4,5,6,7,8,9,10,11,12 However,
little is known about the interplay and possible trade-offs between the different
temporal and spectral acoustic features during these vocal exchanges.2,13,14 Nightingales
can flexibly match the pitch of their tonal “whistle songs” in real time during
counter-singing duels.15,16 Here, we show that the syllable duration of whistle
playbacks could alter the song responses of wild nightingales, causing their whistle
duration distribution to shift toward the presented stimulus duration. When exposed
to whistle playbacks featuring unnatural combinations of pitch and duration, nightingales
demonstrate a flexible trade-off between pitch matching and temporal imitation,
yet they are constrained by their vocal repertoire. They selectively adapted their
vocal responses to approximate these novel stimuli, aligning them with their natural
whistle repertoire. We developed a computational model of nightingale whistle-matching
behavior that revealed a hierarchical organization of acoustic feature production.
During whistle matching, the feature integration process is constrained by the
duration of syllables, and pitch matching follows within this temporal framework,
forcing a trade-off between the two features. Our findings reveal a complex interplay
between the spectral and temporal domains that shapes song-matching behavior.

text: Copper chalcogenides offer high charge mobility and low lattice thermal conductivity
but suffer from structural instability due to dynamic Cu+ migration. Here, we
report a colloidal hot-injection synthesis of ternary cesium copper selenide (CsCu5Se3)
nanocrystals (NCs), achieving precise control over phase, size, and morphology
through tailored precursor-ligand modulation. This strategy enabled systematic
exploration of stable and metastable Cs–Cu–Se phases and mechanistic investigation
of nucleation and growth, providing insight into phase modulation and dimensional
control at the nanoscale. CsCu5Se3 NCs exhibit low lattice thermal conductivity
(∼0.5 Wm–1K–1) and an experimental zT of 0.27 at 718 K. Complementary first-principles
calculations, consistent with experimental electronic and optical responses, predict
a zT of 1.05 at 1000 K. These findings elucidate the formation dynamics of CsCu5Se3
and establish ABZ (A = alkali, B = metal, Z = chalcogen) NCs as tunable platforms
for advanced functional applications.

text: C(sp2)–heteroatom couplings operating via NiI/NiIII catalysis have emerged
as an alternative to canonical Pd0/PdII systems that require complex ligand architectures.
Despite intensive research efforts during the past decade, catalytic methods employing
this approach are still mostly confined to activated starting materials and require
high catalyst loadings due to the low catalytic activity of NiI and undesired
catalyst deactivation events. This article highlights recent advances in the field
toward solving these long-standing challenges. We survey strategies that streamline
the generation of catalytically competent NiI species from bench-stable NiII precatalysts,
and discuss mechanistic studies that shed light on deactivation pathways and the
rate-determining oxidative addition of aryl halides. In the final section, we
highlight recently developed synthetic methodologies, which provide evidence that
limitations can indeed be addressed by working at elevated temperatures, employing
alternative electrophiles, harnessing the benefits of additives, or fine-tuning
the metal’s reactivity through the ligand field.

text: We have addressed convective self‐aggregation (CSA) in steady and oscillating
sea surface temperature (SST) and solar radiation (SOLIN) cloud‐resolving model
simulations in a non‐rotating radiative‐convective equilibrium (RCE) framework.
Our experiment designs are motivated by land‐ocean heterogeneity of atmospheric
convection. The steady and oscillating forcings are idealizations of ocean and
land conditions, respectively, based on their differences in heat capacities.
In both kinds of simulations, the diurnal mean SST and SOLIN are the same, and
both SST and SOLIN are only varied in time (i.e., they are spatially homogeneous
at any given time). We find that diurnally oscillating forcing accelerates CSA.
Stronger long‐wave cooling in dry regions at night and during the warm SST phase
(late afternoon) both allow the long‐wave feedback, known to favor aggregation,
to intensify compared to steady forcing simulations. In addition to the long‐wave,
reduced short‐wave warming in dry regions (during the day) further enhances radiative
cooling there compared to moist regions. Overall, the radiative cooling is enhanced
in dry regions compared to neighboring moist convective regions. A dry subsidence
is driven by this net radiative (short‐wave plus long‐wave) cooling, consistent
with earlier work on CSA. Stronger radiative cooling allows stronger subsidence
which allows low‐level circulation to more efficiently transport moisture and
energy up‐gradient, driving convection to aggregate faster. We also note a sensitivity
of our experimental setup to initial conditions, more so at warmer SST. This stochastic
behavior might be critical in reconciling the differences of opinion regarding
the response of convection aggregation to oscillating SST forcing.

text: In this paper, we review recent results on stability and instability in logarithmic
Sobolev inequalities, with a particular emphasis on strong norms. We consider
several versions of these inequalities on the Euclidean space, for the Lebesgue
and the Gaussian measures, and discuss their differences in terms of moments and
stability. We give new and direct proofs, as well as examples and discuss the
stability of a logarithmic uncertainty principle. Although we do not cover all
aspects of the topic, we hope to contribute to establishing the state of the art.

text: According to the scientific consensus, tropical convection must decrease with
global warming. This decrease is manifested by a decrease of the mass transported
in the upward branch of the atmospheric overturning circulation – the convective
mass flux – and a connected decrease of high clouds in the tropics, with implications
for climate sensitivity. By using kilometer-scale simulations in radiative-convective
equilibrium and a convective tracking algorithm, we show that no such decrease
occurs in storms when taken individually and that the mass transport per storm
increases instead. Storms can achieve this result by aggregating more surface
of the convective cores – the inner part of the storm doing the vertical transport
– so that the decrease of tropical convection is actually explained by a decrease
in the total number of storms. There is little variation of the mean pressure
velocity in the cores of the storms, a robust finding of this study. This remarkable
invariance of the mean pressure velocity points to an emerging property of convection
that should receive more attention in future studies.

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: '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.
