text: 'Patho-mechanistic origins of ulcerative colitis are still poorly understood.
The actin cross-linker filamin A (FLNA) impacts cellular responses through interaction
with cytosolic proteins. Posttranscriptional A-to-I editing generates two forms
of FLNA: genome-encoded FLNAQ and FLNAR. FLNA is edited in colon fibroblasts,
smooth muscle cells, and endothelial cells. We found that the FLNA editing status
determines colitis severity. Editing was highest in healthy colons and reduced
during murine and human colitis. Mice that exclusively express FLNAR were highly
resistant to DSS-induced colitis, whereas fully FLNAQ animals developed severe
inflammation. While the genetic induction of FLNA editing influenced transcriptional
states of structural cells and microbiome composition, we found that FLNAR exerts
protection specifically via myeloid cells, which are physiologically unedited.
Introducing fixed FLNAR did not hamper cell migration but reduced macrophage inflammation
and rendered neutrophils less prone to NETosis. Thus, loss of FLNA editing correlates
with colitis severity, and targeted editing of myeloid cells serves as a novel
therapeutic approach in intestinal inflammation.'

text: "Context. The observed Lyman-alpha (Lyα) line profile is a convolution of
the complex Lyα radiative transfer taking place in the interstellar, circumgalactic,
and intergalactic media (ISM, CGM, and IGM, respectively). Discerning the different
components of the Lyα line is crucial in order to use it as a probe of galaxy
formation or the evolution of the IGM.\r\n\r\nAims. We aim to present the second
version of zELDA (redshift Estimator for Line profiles of Distant Lyman-Alpha
emitters), an open-source Python module focused on modelling and fitting observed
Lyα line profiles. This new version of zELDA focuses on disentangling the galactic
from the IGM effects.\r\n\r\nMethods. We built realistic Lyα line profiles that
include the ISM and IGM contributions by combining the Monte Carlo radiative-transfer
simulations for the so-called shell model (ISM) and IGM transmission curves generated
from TNG100. We used these mock line profiles to train different artificial neural
networks. These use the observed spectrum as input and the outflow parameters
of the best fitting ‘shell model’ as output along with the redshift and Lyα emission
IGM escape fraction of the source.\r\n\r\nResults. We measured the accuracy of
zELDA on mock Lyα line profiles. We find that zELDA is capable of reconstructing
the ISM emerging Lyα line profile with high levels of accuracy (Kolmogórov-Smirnov<0.1)
for 95% of the cases for HST/COS-like observations and 80% for MUSE-WIDE-like
observations. zELDA is able to measure the IGM transmission with typical uncertainties
below 10% for HST/COS and MUSE-WIDE data.\r\n\r\nConclusions. This work represents
a step forward in the high-precision reconstruction of IGM-attenuated Lyα line
profiles. zELDA allows the disentanglement of the galactic and IGM contribution
shaping the Lyα line shape and thus allows us to use Lyα as a tool to study galaxy
and ISM evolution."

text: We present an analysis of the UV continuum slope, β, using a sample of 726
galaxies with z > 4, selected from a mixture of JWST ERS, GTO, and GO observational
programs. We considered only spectroscopic data obtained with the low-resolution
(R ∼ 30 − 300) PRISM/CLEAR NIRSpec configuration. Studying the correlation between
β and MUV, we find an overall decreasing trend, described by β = ( − 0.055 ± 0.017)MUV + ( − 2.98 ± 0.34).
This is consistent with previous studies, where brighter galaxies show redder
β values. However, when analyzing the trend in separate redshift bins, we find
that at high redshift the relation becomes much flatter and is consistent with
a flat slope within 1σ. Furthermore, we find that β tends to decrease with redshift,
following β = ( − 0.075 ± 0.010)z + ( − 1.496 ± 0.056). This is consistent with
most recent results showing a steepening of the spectra at higher z. We selected
a sample of galaxies with extremely blue slopes (i.e., β < −2.6). Such slopes
are steeper than predicted by stellar evolution models – even for dust-free, young,
metal-poor populations – when the contribution of nebular emission is included.
We selected 44 extremely blue galaxies (XBGs) and investigated the possible physical
origin of their steep slopes by comparing them to a subsample of redder galaxies
(matched in Δz = ±0.5 and ΔMUV = ±0.2). We find that XBGs have younger stellar
populations, stronger ionization fields, lower dust attenuation, and lower but
not pristine metallicity (∼10% Z⊙) compared to red galaxies. However, these properties
alone cannot explain the extreme β values. Using indirect inference of Lyman continuum
escape with the most recent models, we estimated the escape fraction fesc > 10%
in at least 25% of the XBGs, whereas all the red sources exhibit much lower fesc
values. A reduced nebular continuum contribution – resulting from either a high
escape fraction or a bursty star formation history – is likely the origin of the
extremely blue slopes.

text: JWST observations have uncovered a new population of red, compact objects
at high redshifts dubbed “little red dots” (LRDs), which typically show broad
emission lines and are thought to be dusty active galactic nuclei (AGNs). Some
of their other features, however, challenge the AGN explanation, such as prominent
Balmer breaks and extremely faint or even missing metal high-ionization lines,
X-ray, or radio emission, including in deep stacks. Time variability is another
robust test of AGN activity. Here, we exploit the z = 7.045 multiply imaged LRD
A2744-QSO1, which offers a particularly unique test of variability due to lensing-induced
time delays between the three images spanning 22 yr (2.7 yr in the rest-frame),
to investigate its photometric and spectroscopic variability. We find the equivalent
widths (EWs) of the broad Hα and Hβ lines, which are independent of magnification
and other systematics, to exhibit significant variations, of up to 18 ± 3% for
Hα and up to 22 ± 8% in Hβ, on a timescale of 875 d (2.4 yr) in the rest-frame.
This suggests that A2744-QSO1 is indeed an AGN. We find no significant photometric
variability beyond the limiting systematic uncertainties, so it currently cannot
be determined whether the EW variations are due to line-flux or continuum variability.
These results are consistent with a typical damped random walk variability model
for an AGN such as A2744-QSO1 (MBH = 4 × 107 M⊙) given the sparse sampling of
the light curve with the available data. Our results therefore support the AGN
interpretation of this LRD, and highlight the need for further photometric and
spectroscopic monitoring in order to build a detailed and reliable light curve.

text: "The separation logic framework Iris has been built on the premise that all
assertions are stable, meaning they unconditionally enjoy the famous frame rule.
This gives Iris—and the numerous program logics that build on it—very modular
reasoning principles. But stability also comes at a cost. It excludes a core feature
of the Viper verifier family, heap-dependent expression assertions, which lift
program expressions to the assertion level in order to reduce redundancy between
code and specifications and better facilitate SMT-based automation.\r\nIn this
paper, we bring heap-dependent expression assertions to Iris with Daenerys. To
do so, we must first revisit the very core of Iris, extending it with a new form
of unstable resources (and adapting the frame rule accordingly). On top, we then
build a program logic with heap-dependent expression assertions and lay the foundations
for connecting Iris to SMT solvers. We apply Daenerys to several case studies,
including some that go beyond what Viper and Iris can do individually and others
that benefit from the connection to SMT."

text: 'There has been a recent upsurge of interest in formal, machine-checked verification
of timing guarantees for C implementations of real-time system schedulers. However,
prior work has only considered tick-based schedulers, which enjoy a clearly defined
notion of time: the time "quantum". In this work, we present a new approach to
real-time systems verification for interrupt-free schedulers, which are commonly
used in deeply embedded and resource-constrained systems but which do not enjoy
a natural notion of periodic time. Our approach builds on and connects two recently
developed Rocq-based systems—RefinedC (for foundational C verification) and Prosa
(for verified response-time analysis)—adapting the former to reason about timed
traces and the latter to reason about overheads. We apply the resulting system,
which we call RefinedProsa, to verify Rössl, a simple yet representative, fixed-priority,
non-preemptive, interrupt-free scheduler implemented in C.'

text: Simplets are elementary units within simplicial complexes and are fundamental
for analyzing the structure of simplicial complexes. Previous efforts have mainly
focused on accurately counting or approximating the number of simplets rather
than studying their frequencies. However, analyzing simplet frequencies is more
practical for large-scale simplicial complexes. This paper introduces the Simplet
Frequency Distribution (SFD) vector, which enables the analysis of simplet frequencies
in simplicial complexes. Additionally, we provide a bound on the sample complexity
required to approximate the SFD vector using any uniform sampling-based algorithm
accurately. We extend the definition of simplet frequency distribution to encompass
simplices, allowing for the analysis of simplet frequencies within simplices of
simplicial complexes. This paper introduces the Simplet Degree Vector (SDV) and
the Simplet Degree Centrality (SDC), facilitating this analysis for each simplex.
Furthermore, we present a bound on the sample complexity required for accurately
approximating the SDV and SDC for a set of simplices using any uniform sampling-based
algorithm. We also introduce algorithms for approximating SFD, geometric SFD,
SDV, and SDC. We also validate the theoretical bounds with experiments on random
simplicial complexes and demonstrate the practical application through a case

text: The specific introduction of 1H-13C or 1H-15N moieties into otherwise deuterated
proteins holds great potential for high-resolution solution and magic-angle spinning
(MAS) NMR studies of protein structure and dynamics. Arginine residues play key
roles for example at active sites of enzymes. Taking advantage of a chemically
synthesized Arg with a 13C-1H2 group in an otherwise deuterated backbone, we demonstrate
here the usefulness of proton-detected arginine MAS NMR approaches to probe arginine
dynamics. In experiments on crystalline ubiquitin and the 134 kDa tetrameric enzyme
malate dehydrogenase we detected a wide range of motions, from sites that are
rigid on time scales of at least tens of milliseconds to residues undergoing predominantly
nanosecond motions. Spin-relaxation and dipolar-coupling measurements enabled
quantitative determination of these dynamics. We observed microsecond dynamics
of residue Arg54 in crystalline ubiquitin, whose backbone is known to sample different
β-turn conformations on this time scale. The labeling scheme and experiments presented
here expand the toolkit for high-resolution proton-detected MAS NMR

text: The acquisition of cellular identity requires large-scale alterations in cellular
state. The noncanonical proteasome activator PSME3 is known to regulate diverse
cellular processes, but its importance for differentiation remains unclear. Here,
we demonstrate that PSME3 binds dynamically to highly active promoters over the
course of differentiation. However, loss of PSME3 does not globally affect mRNA
transcription. We find instead that PSME3 influences the levels of several adhesion-related
proteins and acts upstream of the HSP90 co-chaperone NUDC to regulate cell motility
and myoblast differentiation in a proteasome-independent manner. Our findings
reveal several new facets of PSME3 functionality and highlight its importance
for the differentiation of myogenic cells.

text: It has been suggested that giant planet occurrence peaks for stars with M*
≈ 3 M⊙ at a value a factor of 4 higher than observed for solar-mass stars. This
population of giant planets predicted to frequently orbit main-sequence B stars
at a ≈ 10 au is difficult to characterize during the few hundred million years
while fusion persists in their host stars. By the time those stars become massive,
young white dwarfs, any giant planets present would still be luminous as a consequence
of their recent formation. From an initial sample of 2195 Gaia-identified massive,
young white dwarfs, we use homogeneous Spitzer Infrared Array Camera (IRAC) photometry
to search for evidence of unresolved giant planets. For 30 systems, these IRAC
data provide sensitivity to objects with M ≲ 10 MJup, and we identify one candidate
with M ≈ 4 MJup orbiting the white dwarf GALEX J071816.4+373139. Correcting for
the possibility that some of the white dwarfs in our sample result from mergers,
we find a giant planet occurrence n GP = 0.11+0.13-0.07 for stars with initial
masses M* ≳ 3 M⊙. Our occurrence inference is consistent with both the Doppler-inferred
occurrence of giant planets orbiting M* ≈ 2 M⊙ giant stars and the theoretically
predicted factor of 4 enhancement in the occurrence of giant planets orbiting
M* ≈ 3 M⊙ stars relative to solar-mass stars. Future James Webb Space Telescope
NIRCam observations of our sample would provide sensitivity to Saturn-mass planets
and thereby a definitive estimate of the occurrence of giant planets orbiting
stars with M* ≳ 3 M⊙.

text: Multiagent learning is challenging when agents face mixed-motivation interactions,
where conflicts of interest arise as agents independently try to optimize their
respective outcomes. Recent advancements in evolutionary game theory have identified
a class of “zero-determinant” strategies, which confer an agent with significant
unilateral control over outcomes in repeated games. Building on these insights,
we present a comprehensive generalization of zero-determinant strategies to stochastic
games, encompassing dynamic environments. We propose an algorithm that allows
an agent to discover strategies enforcing predetermined linear (or approximately
linear) payoff relationships. Of particular interest is the relationship in which
both payoffs are equal, which serves as a proxy for fairness in symmetric games.
We demonstrate that an agent can discover strategies enforcing such relationships
through experience alone, without coordinating with an opponent. In finding and
using such a strategy, an agent (“enforcer”) can incentivize optimal and equitable
outcomes, circumventing potential exploitation. In particular, from the opponent’s
viewpoint, the enforcer transforms a mixed-motivation problem into a cooperative
problem, paving the way for more collaboration and fairness in multiagent systems.

text: Recently discovered nanofluidic memristors, have raised promises for the development
of iontronics and neuromorphic computing with ions. Ionic memory effects are related
to ion dynamics inside nanochannels, with timescales associated with the manifold
physicochemical phenomena occurring at confined interfaces. Here, we explore experimentally
the frequency-dependent current–voltage response of model nanochannels—namely
glass nanopipettes—to investigate memory effects in ion transport. This characterisation,
which we refer to as mem-spectrometry, highlights two characteristic frequencies,
associated with short and long timescales of the order of 50 ms and 50 s in the
present system. Whereas the former can be associated with ionic diffusion, very
long timescales are difficult to explain with conventional transport phenomena.
We develop a minimal model accounting for these mem-spectrometry results, pointing
to surface charge regulation and ionic adsorption-desorption as possible origins
for the long-term memory. Our work demonstrates the relevance of mem-spectrometry
to highlight subtle ion transport properties in nanochannels, giving hereby new
insights on the mechanisms governing ion transport and current rectification in
charged conical nanopores.

text: "Context. Investigating the ionizing emission of star-forming galaxies and
the escape fraction of ionizing photons is critical to understanding their contribution
to reionization and their impact on the surrounding environment. The number of
ionizing photons available to reionize the intergalactic medium (IGM) depends
on not only the abundance of galaxies but also their efficiency in producing ionizing
photons (ξion). This quantity is thus fundamental to quantify the role of faint
versus bright sources in driving this process, as we must assess their relative
contribution to the total ionizing emissivity.\r\n\r\nAims. Our goal is to estimate
the ξion using Balmer lines (Hα or Hβ) in a sample of 761 galaxies at 4 ≤ z ≤ 10
selected from different JWST spectroscopic surveys. We aim to determine the redshift
evolution of ξion and the relation of ξion with the physical properties of the
galaxies.\r\n\r\nMethods. We used the available HST and JWST photometry to perform
a spectral energy distribution (SED) fitting in the sample to determine their
physical properties and relate them with ξion. We used the BAGPIPES code for the
SED fitting and assumed a delayed exponential model for the star formation history.
We used the NIRSpec spectra from prism or grating configurations to estimate Balmer
luminosities, and then constrained ξion values after dust correction.\r\n\r\nResults.
We find a mean value of 1025.22 Hz erg−1 for ξion in the sample with an observed
scatter of 0.42 dex. We find an increase in the median values of ξion with redshift
from 1025.09 Hz erg−1 at z ∼ 4.18 to 1025.28 Hz erg−1 at z ∼ 7.14, confirming
the redshift evolution of ξion found in other studies. Regarding the relation
between ξion and physical properties, we find a decrease in ξion with increasing
stellar mass, indicating that low-mass galaxies are efficient producers of ionizing
photons. We also find an increase in ξion with increasing specific star formation
rate (sSFR) and increasing UV absolute magnitude. This indicates that faint galaxies
and galaxies with high sSFR are also efficient producers. We also investigated
the relation of ξion with the rest-frame equivalent width (EW) of [OIII]λ5007
and find that galaxies with the higher EW([OIII]λ5007) are more efficient producers
of ionizing photons, with the best fit leading to the relation log(ξion) = 0.43 × log(EW[OIII])+23.99.
Similarly, we find that galaxies with higher O32 = [OIII]λ5007/[OII]λλ3727,3729
and lower gas-phase metallicities (based on the R23 = ([OIII]λλ4959,5007+[OII]λλ3727,3729)/Hβ
calibration) show higher ξion values."

text: In the dynamic arena of innovation, the relations between academia and industry
are a keystone for breakthroughs and practical applications. Yet, the groundwork
of these pivotal University-Industry (U-I) partnerships remains covered in complexity.
This paper delves into these intricate relations, unraveling the factors that
help successful collaborations. Grounded in the Resource-Based Theory, our study
transcends traditional analytical boundaries, leveraging a neural network model
to understand a comprehensive dataset from the UK’s Higher Education Statistics
Agency, SCIMAGO Rankings, and Clarivate Publications. This novel approach helps
to make clear the interplay of academic load, administrative support, scientific
output, and university rank in sculpting U-I collaboration dynamics. Our findings
suggest that reduced academic load and robust administrative support significantly
bolster U-I collaborations. However, the influence of scientific output and university
ranking is more nuanced, challenging the common belief. High scientific output,
while indicative of expertise, doesn't always align with industry goals. Similarly,
while higher-ranked universities could attract more collaborations, the benefits
are not universal. This paper not only contributes to a deeper understanding of
U-I collaborations, but also provides actionable insights for university administrators,
policymakers, and industry leaders. In a world where innovation is key, understanding
these collaborative dynamics is crucial for fostering partnerships that push the
boundaries of research and practical application.

text: "In the stochastic population protocol model, we are given a connected graph
with n nodes, and in every time step, a scheduler samples an edge of the graph
uniformly at random and the nodes connected by this edge interact. A fundamental
task in this model is stable leader election, in which all nodes start in an identical
state and the aim is to reach a configuration in which (1)\r\nexactly one node
is elected as leader and (2) this node remains as the unique leader no matter
what sequence of interactions follows. On cliques, the complexity of this problem
has recently been settled: time-optimal protocols stabilize in (n log n) expected
steps using (log log n) states, whereas protocols that use O(1) states require
(n2) expected steps. In this work, we investigate the complexity of stable leader
election on graphs. We provide the first non-trivial time lower bounds on general
graphs, showing that, when moving beyond cliques, the complexity of stable leader
election can range from O(1) to (n3) expected steps. We describe a protocol that
is time-optimal on many graph families, but uses polynomially-many states. In
contrast, we give a near-time-optimal protocol that uses only O(log2 n) states
that is at most a factor O(log n) slower. Finally, we observe that for many graphs
the constant-state protocol of Beauquier et al. [OPODIS 2013] is at most a factor
O(n log n) slower than the fast polynomial-state protocol, and among constant-state
protocols, this protocol has near-optimal average case complexity on dense random
graphs."

text: "Dynamically maintaining the minimum cut in a graph G under edge insertions
and deletion is a fundamental problem in dynamic graph algorithms for which no
conditional lower bound on the time per operation exists. In an n-node graph the
best known (1 + o (1))-approximate algorithm takes update time [14]. If the minimum
cut is guaranteed to be (log n )o (1), a deterministic exact algorithm with n
o (1) update time exists [8].\r\nWe present the first fully dynamic algorithm
for (1 + o (1))-approximate minimum cut with n o(1) update time. Our main technical
contribution is to show that it suffices to consider small-volume cuts in suitably
contracted graphs."

text: nspired by Richard Feynman’s 1959 lecture and the 1966 film Fantastic Voyage,
the field of micro/nanorobots has evolved from science fiction to reality, with
significant advancements in biomedical and environmental applications. Despite
the rapid progress, the deployment of functional micro/nanorobots remains limited.
This review of the technology roadmap identifies key challenges hindering their
widespread use, focusing on propulsion mechanisms, fundamental theoretical aspects,
collective behavior, material design, and embodied intelligence. We explore the
current state of micro/nanorobot technology, with an emphasis on applications
in biomedicine, environmental remediation, analytical sensing, and other industrial
technological aspects. Additionally, we analyze issues related to scaling up production,
commercialization, and regulatory frameworks that are crucial for transitioning
from research to practical applications. We also emphasize the need for interdisciplinary
collaboration to address both technical and nontechnical challenges, such as sustainability,
ethics, and business considerations. Finally, we propose a roadmap for future
research to accelerate the development of micro/nanorobots, positioning them as
essential tools for addressing grand challenges and enhancing the quality of life.

text: While the most widely used CRISPR-Cas enzyme is the Cas9 endonuclease from
Streptococcus pyogenes (Cas9), it exhibits single-turnover enzyme kinetics which
leads to long residence times on product DNA. This blocks access to DNA repair
machinery and acts as a major bottleneck during CRISPR-Cas9 gene editing. Cas9
can eventually be removed from the product by extrinsic factors, such as translocating
polymerases, but the mechanisms contributing to Cas9 dissociation following cleavage
remain poorly understood. Here, we employ truncated guide RNAs as a strategy to
weaken PAM-distal nucleic acid interactions and promote faster enzyme turnover.
Using kinetics-guided cryo-EM, we examine the conformational landscape of a multi-turnover
Cas9, including the first detailed snapshots of Cas9 dissociating from product
DNA. We discovered that while the PAM-distal product dissociates from Cas9 following
cleavage, tight binding of the PAM-proximal product directly inhibits re-binding
of new targets. Our work provides direct evidence as to why Cas9 acts as a single-turnover
enzyme and will guide future Cas9 engineering efforts.

text: The problem of mobile impurities in quantum baths is of fundamental importance
in many-body physics. There has recently been significant progress regarding our
understanding of this due to cold atom experiments, but so far it has mainly been
concerned with cases where the bath has no or only weak interactions, or the impurity
interacts weakly with the bath. Here, we address this gap by developing a new
theoretical framework for exploring a mobile impurity interacting strongly with
a highly correlated bath of bosons in the quantum critical regime of a Mott insulator
(MI) to superfluid (SF) quantum phase transition. Our framework is based on a
powerful quantum Gutzwiller (QGW) description of the bosonic bath combined with
diagrammatic field theory for the impurity-bath interactions. By resumming a selected
class of diagrams to infinite order, a rich picture emerges where the impurity
is dressed by the fundamental modes of the bath, which change character from gapped
particle-hole excitations in the MI to Higgs and gapless Goldstone modes in the
SF. This gives rise to the existence of several quasiparticle (polaron) branches
with properties reflecting the strongly correlated environment. In particular,
one polaron branch exhibits a sharp cusp in its energy, while a new ground-state
polaron emerges at the O(2) quantum phase transition point for integer filling,
which reflects the nonanalytic behavior at the transition and the appearance of
the Goldstone mode in the SF phase. Smooth versions of these features are inherited
in the polaron spectrum away from integer filling due to the influence of Mott
physics on the bosonic bath. We furthermore compare our diagrammatic results with
quantum Monte Carlo calculations, obtaining excellent agreement. This accuracy
is quite remarkable for such a highly non-trivial case of strong interactions
between the impurity and bosons in a maximally correlated quantum critical regime,
and it establishes the utility of our framework. Finally, our results show how
impurities can be used as quantum sensors and highlight fundamental differences
between experiments performed at a fixed particle number or a fixed chemical potential.

text: "A long-standing conjecture of Eckhoff, Linhart, and Welzl, which would generalize
McMullen’s Upper Bound Theorem for polytopes and refine asymptotic bounds due
to Clarkson, asserts that for k ⩽ ⌊(n-d-2)/2⌋, the complexity of the (⩽ k)-level
in a simple arrangement of n hemispheres in S^d is maximized for arrangements
that are polar duals of neighborly d-polytopes. We prove this conjecture in the
case n = d+4. By Gale duality, this implies the following result about crossing
numbers: In every spherical arc drawing of K_n in S² (given by a set V ⊂ S² of
n unit vectors connected by spherical arcs), the number of crossings is at least
1/4 ⌊n/2⌋ ⌊(n-1)/2⌋ ⌊(n-2)/2⌋ ⌊(n-3)/2⌋. This lower bound is attained if every
open linear halfspace contains at least ⌊(n-2)/2⌋ of the vectors in V.\r\nMoreover,
we determine the space of all linear and affine relations that hold between the
face numbers of levels in simple arrangements of n hemispheres in S^d. This completes
a long line of research on such relations, answers a question posed by Andrzejak
and Welzl in 2003, and generalizes the classical fact that the Dehn-Sommerville
relations generate all linear relations between the face numbers of simple polytopes
(which correspond to the 0-level).\r\nTo prove these results, we introduce the
notion of the g-matrix, which encodes the face numbers of levels in an arrangement
and generalizes the classical g-vector of a polytope."
