text: We show a local rigidity result for the integrability of symplectic billiards.
We prove that any domain which is close to an ellipse, and for which the symplectic
billiard map is rationally integrable must be an ellipse as well. This is in spirit
of the result of [2] for Birkhoff billiards.

text: Enforcement of information-flow policies has been extensively studied by language-based
approaches over the past few decades. In this paper, we propose an alternative,
novel, general, and effective approach using enforcement of hyperproperties– a
powerful formalism for expressing and reasoning about a wide range of information-flow
security policies. We study black- vs. gray- vs. white-box enforcement of hyperproperties
expressed by nondeterministic finite-word hyperautomata (NFH), where the enforcer
has null, some, or complete information about the implementation of the system
under scrutiny. Given an NFH, in order to generate a runtime enforcer, we reduce
the problem to controller synthesis for hyperproperties and subsequently to the
satisfiability problem for quantified Boolean formulas (QBFs). The resulting enforcers
are transferable with low-overhead. We conduct a rich set of case studies, including
information-flow control for JavaScript code, as well as synthesizing obfuscators
for control plants.

text: Collective cell migration is coordinated by the front-to-rear intercellular
propagation of EGFR-Ras-ERK pathway activation. However, the molecular mechanisms
integrating front-to-rear information into this intercellular signaling cascade,
particularly the determinants of cellular front-side specification, remain elusive.
We visualized the activity of EGFR, Ras, Rac1 and Rab5A (hereafter Rab5) by using
FRET biosensors and chemogenetic tools. Whereas EGFR activation was uniformly
observed within cells, Ras activation was biased to the front side within cells.
The polarized Ras activation depended on Merlin and Rac1, which also showed front-biased
activation. Furthermore, Rab5, a crucial regulator of cell migration, demonstrated
similar front-biased activation and was found to function downstream of Ras while
being necessary for Rac1 activation. Thus, the positive feedback loop consisting
of Ras, Rab5 and Rac1 is activated primarily at the front of collectively migrating
cells. These findings offer new spatio-temporal insight into processing front–rear
information during collective cell migration.

text: Certification was made mandatory for the first time in the latest hardware
model checking competition. In this case study, we investigate the trade-offs
of requiring certificates for both passing and failing properties in the competition.
Our evaluation shows that participating model checkers were able to produce compact,
correct certificates that could be verified with minimal overhead. Furthermore,
the certifying winner of the competition outperforms the previous non-certifying
state-of-the-art model checker, demonstrating that certification can be adopted
without compromising model checking efficiency.

text: High-entropy alloys (HEAs) show great potential for catalyzing complex multi-step
reactions, but optimizing their parameters, i.e., composition, but also their
crystallinity and morphology, remains a significant challenge. In this study,
FeCoNiMoW HEAs are synthesized into either amorphous nanosheets (HEANS) or crystalline
nanoparticles (HEANP), which are then used to catalyze the lithium–sulfur (Li–S)
reaction of Li–S batteries (LSBs). Evaluations in symmetric cells, coin cells,
and pouch cells reveal that HEANS significantly enhance LSB performance, achieving
initial discharge capacities up to 1632 mAh g−1. The batteries also exhibit excellent
cycling stability over 1000 cycles at 3Cand maintain high-rate performance up
to 10C with a capacity of 614 mAh g−1. Comprehensive in situ analyses and density
functional theory calculations demonstrate that amorphous HEANS provide more active
sites, better ionic conductivity and stronger chemical interactions with lithium
polysulfides (LiPS). These properties effectively suppress the shuttle effect,
promote the complete S8 → Li2S conversion by reducing the impedance of the solid-electrolyte
interphase, and accelerate the Li2S4 → Li2S2 step by lowering the nucleation energy
barrier. Overall, this study highlights the superior catalytic properties of amorphous
2D HEAs in LSBs and offers new insights into the mechanisms of LiPS conversion.

text: We study the physical origin and spectroscopic impact of extreme nebular emission
in high-redshift galaxies. The nebular continuum, which can appear during an extreme
starburst, is of particular importance as it tends to redden UV slopes and has
a significant contribution to the UV luminosities of galaxies. Furthermore, its
shape can be used to infer the gas density and temperature of the interstellar
medium. First, we provide a theoretical background, showing how different stellar
populations (SPS models, initial mass functions (IMFs), and stellar temperatures)
and nebular conditions impact observed galaxy spectra. We demonstrate that, for
systems with strong nebular continuum emission, 1) UV fluxes can increase by up
to 0.7~mag (or more in the case of hot/massive stars) above the stellar continuum,
which may help reconcile the surprising abundance of bright high-redshift galaxies
and the elevated UV luminosity density at z>10, 2) at high gas densities, UV slopes
can redden from \beta<-2.5 to \beta\sim-1, 3) observational measurements of \xi_{\rm
ion} are gross underestimates, and 4) UV downturns from two-photon emission can
masquerade as damped Ly\alpha systems. Second, we present a dataset of 58 galaxies
observed with NIRSpec on JWST at 2.510 galaxies, finding
that UV slopes and UV downturns are in some cases redder or steeper than expected
from SPS models, which may hint at more exotic (e.g. hotter/more massive stars
or AGN) ionizing sources.

text: Understanding the rapid formation of supermassive black holes in the early
Universe requires insights into stellar mass growth in host galaxies. Here we
present NIRSpec rest-frame optical spectra and NIRCam imaging from JWST of two
galaxies at z > 6, both hosting moderate-luminosity quasars. These galaxies exhibit
Balmer absorption lines, like low-redshift post-starburst galaxies. Our analyses
of the medium-resolution spectra and multiband photometry show that the bulk of
the stellar mass (log(M*/M☉) ≥ 10.6) formed in starburst episodes at redshift
9 and 7. One of the galaxies shows a clear Balmer break and lacks spatially resolved
Hα emission. It falls well below the star-formation main sequence at z = 6, indicating
quiescence. The other is transitioning to quiescence; together, these massive
galaxies are among the most distant post-starburst systems known. The blueshifted
wings of the quasar [O iii] emission lines indicate quasar-driven outflow, which
possibly influences star formation. Direct stellar velocity dispersion measurements
reveal that one galaxy follows the local black hole mass versus σ* relation whereas
the other is overmassive. The existence of massive post-starburst galaxies hosting
billion-solar-mass black holes in short-lived quasar phases indicates that supermassive
black holes and host galaxies played a principal role in each other’s rapid early
formation.

text: "We present Virgil, a Mid-Infrared Instrument (MIRI) extremely red object
detected with the F1000W filter as part of the MIRI Deep Imaging Survey observations
of the Hubble Ultra Deep Field. Virgil is an Lyα emitter (LAE) at zspec = 6.6312
± 0.0019 (from the Very Large Telescope/MUSE) with a rest-frame UV-to-optical
spectral energy distribution (SED) typical of LAEs at similar redshifts. However,
MIRI observations reveal an unexpected extremely red color at rest-frame near-infrared
(NIR) wavelengths, F444W − F1000W = 2.33 ± 0.06. Such a steep\r\nrise in the NIR,
completely missed without MIRI imaging, is poorly reproduced by models including
only stellar populations and hints toward the presence of an active galactic nucleus,
although alternative explanations such as extreme dust obscuration and strong
nebular continuum and emission lines contribution due to young stellar ages cannot
be completely ruled out. According to the shape of its overall SED, Virgil belongs
to the recently discovered\r\npopulation of little red dots but displays an extended
rest-frame UV-optical wavelength morphology following a 2DSérsic profile with
an average index of n = 0.93+0.85_0.31 and re = 0.49+0.05_0.11 pkpc. Only at
MIRI wavelengths, Virgil is unresolved due to the coarser point-spread function.
This discovery demonstrates the crucial importance of deep MIRI surveys to reveal
the true nature and properties of high-z galaxies that otherwise would be misinterpreted
and raises the question of how common Virgil-like objects could be in the early
Universe."

text: Humanity has long sought inspiration from nature to innovate materials and
devices. As science advances, nature-inspired materials are becoming part of our
lives. Animate materials, characterized by their activity, adaptability, and autonomy,
emulate properties of living systems. While only biological materials fully embody
these principles, artificial versions are advancing rapidly, promising transformative
impacts in the circular economy, health and climate resilience within a generation.
This roadmap presents authoritative perspectives on animate materials across different
disciplines and scales, highlighting their interdisciplinary nature and potential
applications in diverse fields including nanotechnology, robotics and the built
environment. It underscores the need for concerted efforts to address shared challenges
such as complexity management, scalability, evolvability, interdisciplinary collaboration,
and ethical and environmental considerations. The framework defined by classifying
materials based on their level of animacy can guide this emerging field to encourage
cooperation and responsible development. By unravelling the mysteries of living
matter and leveraging its principles, we can design materials and systems that
will transform our world in a more sustainable manner.

text: Reproduction is a fundamental biological process, with organisms reproducing
sexually, asexually, and, in some cases, utilizing both modes of reproduction
within the same population. Does the ability to reproduce through a combination
of asexual and sexual modes offer an evolutionary advantage over relying on either
mode alone? Here, we introduce an empirically driven theoretical model to examine
the dynamics and interplay between sexual and asexual reproduction in stick insect
populations. We analyse it using a novel phase transition approach and corroborate
it using published experimental data. We find that the presence of males can either
increase or decrease the overall population size. However, maintaining an optimal
ratio of parthenogenetic to sexual reproduction is crucial for male resilience,
effectively delaying male extinction. Conversely, extreme levels of parthenogenetic
reproduction—whether too high or too low—can lead to male extinction, emphasizing
the need for a balanced number of virgin females to ensure the persistence of
males. Our model also explains male absence in Carausius morosus and persistence
in Extatosoma tiaratum. Our findings provide valuable insights into the interplay
of reproductive strategies and contribute to broader discussions on the transitions
between sexual and asexual reproduction.

text: Stress granules (SG) are biomolecular condensates that represent an adaptive
response of cells to various stresses, including heat. However, the cell type–specific
function and relevance of SG formation, especially during reproductive development,
are largely not understood. Here, we show that the meiotic A-type cyclin TARDY
ASYNCHRONOUS MEIOSIS (TAM) is recruited to SGs in male meiocytes of Arabidopsis
after exposure to heat. We find that the amino terminus of TAM is necessary and
sufficient for the localization of proteins to meiotic SGs. Swapping the amino
terminus of TAM with the one of its sister protein CYCA1;1 resulted in a separation-of-function
allele of TAM, which prevents the partitioning of TAM to SGs while restoring a
wild-type phenotype in a tam mutant background under nonheat stress conditions.
Notably, plants expressing this TAM version prematurely terminate meiosis under
heat resulting in unreduced gametes. Thus, the formation of TAM-containing SGs
is necessary for genome stability under heat stress.

text: We describe the design, synthesis, and single-molecule junction conductance
of π-electron molecules bearing both radial and linear π-conjugation pathways,
whereby cycloparaphenylene (CPP) radial cores are π-extended linearly with aryl
alkyne substituents as models for previously reported CPP-arylene ethynylene conjugated
polymers. Although radially and linearly conjugated molecules have been studied
previously in isolation as junction-bridging molecular electronic units, this
is the first study to examine molecules where both topologies are operative. Our
results reveal that the presence of radial CPP components within the junction-spanning
pathway leads to a reduction in the conductance of the backbone compared to model
linear phenyl substituents. Through tight-binding and DFT-based calculations,
we attribute this conductance change to intramolecular van der Waals (vdW) interactions
between the CPP ring and the junction-spanning arylene-ethynylene molecular backbone.
These interactions induce changes in the dihedral angles of the backbone, leading
to a reduced overlap of π orbitals within the molecular junction.

text: Let X be a smooth projective hypersurface defined over Q. We provide new bounds
for rational points of bounded height on X. In particular, we show that if X is
a smooth projective hypersurface in Pn with n 4 and degree d 50, then the set
of rational points on X of height bounded by B have cardinality On,d,ε (Bn−2+ε
). If X is smooth and has degree d 6, we improve the dimension growth conjecture
bound. We achieve an analogue result for affine hypersurfaces whose projective
closure is smooth.

text: The first influential hypothesis for sex chromosome evolution was proposed
in 1914 by H. J. Muller, who argued that once recombination was suppressed between
the X and Y chromosomes, Y-linked genes become “sheltered” from selection, leading
to accumulation of recessive loss-of-function (LOF) mutations and decay of Y-linked
genes. The hypothesis fell out of favor in the 1970s because early mathematical
models failed to support it and data on the dominance of lethal mutations were
viewed as incompatible with the hypothesis. We reevaluate the main arguments against
Muller's hypothesis and find that they do not conclusively exclude a role for
sheltering in sex chromosome evolution. By relaxing restrictive assumptions of
earlier models, we show that sheltering promotes fixation of LOF mutations with
sexually dimorphic fitness effects, resulting in decay of X-linked genes that
are exclusively expressed by males and Y-linked genes that are primarily, though
not necessarily exclusively, expressed by females. We further show that drift
and other processes contributing to Y degeneration (i.e. selective interference
and regulatory evolution) expand conditions of Y-linked gene loss by sheltering.
The actual contribution of sheltering to sex chromosome evolution hinges upon
the distribution of dominance and sex-specific fitness effects of LOF mutations,
which we discuss.

text: "Traffic in datacenters may follow some pattern: some pairs of servers communicate
more frequently than others. Demand-oblivious networks may perform poorly for
such workloads, and demand-aware networks optimized for traffic should be used
instead. Unfortunately, not all shapes of networks are feasible in real hardware.
Practical limitations are usually provided in the form of a topology. For example,
a network may be required to be a binary tree, a bounded-degree graph or a Fat
tree.\r\nIn this work, we consider a topology of a binary tree, one of the most
fundamental network topologies. We show that already finding an optimal demand-aware
binary tree network is NP-hard. Then, we explore how various optimization techniques,
including simple local searches, as well as deterministic mutation and crossover
operators, cope with generating efficient tree networks on real-life and synthetic
workloads."

text: "We present the first supermartingale certificate for quantitative \r\n-regular
properties of discrete-time infinite-state stochastic systems. Our certificate
is defined on the product of the stochastic system and a limit-deterministic Büchi
automaton that specifies the property of interest; hence we call it a limit-deterministic
Büchi supermartingale (LDBSM). Previously known supermartingale certificates applied
only to quantitative reachability, safety, or reach-avoid properties, and to qualitative
(i.e., probability 1) \r\n-regular properties.We also present fully automated
algorithms for the template-based synthesis of LDBSMs, for the case when the stochastic
system dynamics and the controller can be represented in terms of polynomial inequalities.
Our experiments demonstrate the ability of our method to solve verification and
control tasks for stochastic systems that were beyond the reach of previous supermartingale-based
approaches."

text: We develop a heuristic for the density of integer points on affine cubic surfaces.
Our heuristic applies to smooth surfaces defined by cubic polynomials that are
log K3, but it can also be adjusted to handle singular cubic surfaces. We compare
our heuristic to Heath-Brown’s prediction for sums of three cubes, as well as
to asymptotic formulae in the literature around Zagier’s work on the Markoff cubic
surface, and work of Baragar and Umeda on further surfaces of Markoff-type. We
also test our heuristic against numerical data for several families of cubic surfaces.
acknowledgement: "The authors owe a debt of thanks to Yonatan Harpaz for asking about
circle method heuristics for log K3 surfaces. His contribution to the resulting
discussion is gratefully acknowledged. Thanks are also due to Andrew Sutherland
for help with numerical data for the equation x^3 + y^3 + z^3 = 1, together with
Alex Gamburd, Amit Ghosh, Peter Sarnak and Matteo Verzobio for their interest in
this paper. Special thanks are due to Victor Wang for helpful conversations about
the circle method heuristics and to the anonymous referee for several useful comments.

text: "Population III stars are possible precursors to early supermassive black
holes (BHs). The presence of soft UV Lyman–Werner (LW) background radiation can
suppress Population III star formation in minihaloes and allow them to form in
pristine atomic-cooling haloes. In the absence of molecular hydrogen (H2) cooling,
atomic-cooling haloes enable rapid collapse with suppressed fragmentation. High
background LW fluxes from preceding star-formation have been proposed to dissociate
H2. This flux can be supplemented by LW radiation from one or more Population
III star(s) in the same halo, reducing the necessary background level. Here, we
consider atomic-cooling haloes in which multiple protostellar cores form close
to one another nearly simultaneously. We assess whether the first star’s LW radiation
can dissociate nearby \r\n, enabling rapid accretion on to a nearby protostellar
core, and the prompt formation of a second, supermassive star (SMS) from warm,
atomically-cooled gas. We use a set of hydrodynamical simulations with the code
enzo, with identical LW backgrounds centred on a halo with two adjacent collapsing
gas clumps. When an additional large local LW flux is introduced, we observe immediate
reductions in both the accretion rates and the stellar masses that form within
these clumps. While the LW flux reduces the H2 fraction and increases the gas
temperature, the halo core’s potential well is too shallow to promptly heat the
gas to >1000 K and increase the second protostar’s accretion rate. We conclude
that this internal LW feedback scenario is unlikely to facilitate SMS or massive
BH seed formation."

text: Zirconia nanocrystals (ZrO2 NCs) are a stable host material for lanthanides,
but their performance lags behind that of the leading NaYF4 nanomaterials. Here,
we leverage surface chemistry and core/shell architectures to uncover the contribution
of dopants at the nanocrystal surface and of dopants in the nanocrystal bulk.
We first assess the doping efficiency by ICP and find that, while Eu is almost
quantitatively incorporated, the other lanthanides (La, Ce, Tb, Tm, Er, Yb) have
about 50% incorporation efficiency over the studied doping range of 1–10%. We
then determine the nanocrystal surface chemistry using NMR spectroscopy, despite
the additional spectral line broadening caused by the paramagnetic lanthanide
dopants. By varying the surface ligands and measuring the photoluminescence, we
resolve the spectroscopic signals that are sensitive to a change in surface chemistry.
Time-resolved emission spectra further reinforce the notion of a bulk component
with a long luminescent lifetime and a surface component with a fast lifetime.
Upon shelling Eu- or Tb-doped zirconia NCs with pure zirconia, the surface component
disappears, and the photoluminescence quantum yield increases. We further functionalized
the surface of the core/shell particles with oleylphosphonic acid ligands to obtain
excellent dispersibility. These results show that lanthanide-doped zirconia NCs
can be engineered to eliminate deactivation pathways.
