text: The brightest steady sources of radiation in the universe, active galactic
nuclei (AGNs), are powered by gas accretion on to a central supermassive black
hole (SMBH). The large sizes and accretion rates implicated in AGN accretion discs
are expected to lead to gravitational instability and fragmentation, effectively
cutting off mass inflow to the SMBH. Radiative feedback from disc-embedded stars
has been invoked to yield marginally stable, steady-state solutions in the outer
discs. Here, we examine the consequences of this star formation with a semi-analytical
model in which stellar-mass black hole (sBH) remnants in the disc provide an additional
source of stabilizing radiative feedback. Assuming star formation seeds the embedded
sBH population, we model the time-evolving feedback from both stars and the growing
population of accreting sBHs. We find that in the outer disc, the luminosity of
the sBHs quickly dominates that of their parent stars. However, because sBHs consume
less gas than stars to stabilize the disc, the presence of the sBHs enhances the
mass flux to the inner disc. As a result, star formation persists over the lifetime
of the AGN, damped in the outer disc, but amplified in a narrow ring in the inner
disc. Heating from the embedded sBHs significantly modifies the disc’s temperature
profile and hardens its spectral energy distribution, and direct emission from
the sBHs adds a new hard X-ray component.

text: Recent hydrodynamical simulations have shown that circumbinary gas disks drive
the orbits of massive binary black holes (BHs) to become eccentric, even when
general relativistic (GR) corrections to the orbit are significant. Here, we study
the GR apsidal precession of eccentric equal-mass massive binary BHs in circumbinary
disks via two-dimensional hydrodynamical simulations. We perform a suite of simulations
comparing precessing and nonprecessing binaries across a range of eccentricities,
semimajor axes, and precession rates. We find that the GR precession of the binary’s
semimajor axis can introduce a dominant modulation in the binary’s accretion rate
and the corresponding high-energy electromagnetic light curves. We discuss the
conditions under which this occurs and its detailed characteristics and mechanism.
Finally, we discuss the potential to observe these precession signatures in electromagnetic-
and gravitational-wave observations, as well as the precession signal’s unique
importance as a potential tool to constrain the mass, eccentricity, and semimajor
axis of binary merger events.

text: "Introduction: Parkinson’s disease (PD) impairs motor preparation due to basal
ganglia dysfunction, contributing to motor deficits. Galvanic Vestibular Stimulation
(GVS), a non-invasive neuromodulation technique, shows promise in enhancing motor
function in PD, but its underlying neural mechanisms are poorly understood. This
study employs a Deep Koopman model to linearize and analyze preparatory EEG dynamics
in PD, hypothesizing that GVS restores cortical activity patterns critical for
motor planning.\r\nMethods: EEG data from 18 PD participants (on/off medication)
and 18 healthy controls were collected during a preparatory phase of a motor task
under three conditions: sham, GVS1 (50–100 Hz multi-sine), and GVS2 (100–150 Hz
multi-sine). A Deep Koopman framework mapped EEG signals into a three-dimensional
latent space for linear dynamical analysis. Temporal dynamics were assessed via
eigenvalue analysis, spatial contributions via regression-based scalp mapping,
and motor performance correlations via Pearson’s coefficients. A Linear Quadratic
Regulator (LQR) simulated control of PD dynamics toward healthy patterns.\r\nResults:
The Deep Koopman model accurately captured EEG dynamics, with eigenvalue analysis
showing no significant temporal dynamic differences across groups. Spatial contribution
analysis revealed that PD-Off sham conditions deviated most from healthy control
EEG patterns, while GVS and medication significantly reduced these deviations,
aligning PD patterns closer to controls. Closer alignment correlated with improved
motor performance metrics, including reduced reaction and squeeze times. LQR control
effectively guided PD neural dynamics toward healthy trajectories in the latent
space.\r\nDiscussion: GVS enhances motor preparation in PD by restoring healthy
cortical EEG patterns, with additive benefits from dopaminergic medication. The
Deep Koopman framework offers a powerful approach for dissecting complex EEG dynamics
and designing targeted neuromodulation strategies. These findings elucidate GVS’s
therapeutic mechanisms and highlight its potential for personalized PD interventions,
warranting further exploration in larger cohorts and varied stimulation protocols."

text: The plant hormone auxin regulates growth and development through at least
two distinct signaling pathways. The nuclear pathway, involving TIR1/AFB receptors,
mediates transcription; whereas the cell surface ABP1-TMK1 auxin perception triggers
global ultrafast phosphorylation response. Here, we revisit the rich history of
the disputed ABP1 auxin receptor, highlighting recent findings of the involvement
of TMKs and other molecular components and focusing on their role in auxin canalization-mediated
development.

text: "The Lovász Local Lemma (LLL) is a powerful tool in probabilistic\r\ncombinatorics
which can be used to establish the existence of objects with certain\r\nproperties.
The breakthrough paper by Moser & Tardos (STOC’09 and JACM 2010)\r\nand follow-up
work revealed that the LLL has intimate connections with a class of\r\nstochastic
local search algorithms for finding such desirable objects.\r\nBesides conditions
for convergence, many other natural questions can be asked\r\nabout algorithms;
for instance, “are they parallelizable?”, “how many solutions can\r\nthey output?”,
“what is the expected ‘weight’ of a solution?”. These questions and\r\nmore have
been answered for a class of LLL-inspired algorithms called commutative. In\r\nthis
paper we introduce a new, very natural and more general notion of commutativity\r\n(essentially
matrix commutativity) which allows us to show a number of new refined\r\nproperties
of LLL-inspired local search algorithms with significantly simpler proofs."

text: 'This paper deals with the algorithmic aspects of solving feasibility problems
of semidefinite programming (SDP), aka linear matrix inequalities (LMIs). Since
in some SDP instances all feasible solutions have irrational entries, numerical
solvers that work with rational numbers can only find an approximate solution.
We study the following question: Is it possible to certify feasibility of a given
SDP using an approximate solution that is sufficiently close to some exact solution?
Existing approaches make the assumption that there exist rational feasible solutions
(and use techniques such as rounding and lattice reduction algorithms). We propose
an alternative approach that does not need this assumption. More specifically,
we show how to construct a system of polynomial equations whose set of real solutions
is guaranteed to have an isolated correct solution (assuming that the target exact
solution is maximum-rank). This allows, in particular, for us to use algorithms
from real algebraic geometry for solving systems of polynomial equations, yielding
a hybrid (or symbolic-numerical) method for SDPs. We experimentally compare it
with a pure symbolic method in [D. Henrion, S. Naldi, and M. Safey El Din, SIAM
J. Optim., 26 (2016), pp. 2512–2539]; the hybrid method was able to certify feasibility
of many SDP instances on which the aforementioned paper failed. Our approach may
have further applications, such as refining an approximate solution using methods
of numerical algebraic geometry for systems of polynomial equations.'

text: Personalized federated learning has emerged as a popular approach to training
on devices holding statistically heterogeneous data, known as clients. However,
most existing approaches require a client to have labeled data for training or
finetuning in order to obtain their own personalized model. In this paper we address
this by proposing FLowDUP, a novel method that is able to generate a personalized
model using only a forward pass with unlabeled data. The generated model parameters
reside in a low-dimensional subspace, enabling efficient communication and computation.
FLowDUP's learning objective is theoretically motivated by our new transductive
multi-task PAC-Bayesian generalization bound, that provides performance guarantees
for unlabeled clients. The objective is structured in such a way that it allows
both clients with labeled data and clients with only unlabeled data to contribute
to the training process. To supplement our theoretical results we carry out a
thorough experimental evaluation of FLowDUP, demonstrating strong empirical performance
on a range of datasets with differing sorts of statistically heterogeneous clients.
Through numerous ablation studies, we test the efficacy of the individual components
of the method.

text: The condensation of charged polymers is an important driver for the formation
of biomolecular condensates. Recent experiments suggest that this mechanism also
controls the clustering of eukaryotic chromosomes during the late stages of cell
division. In this process, interchromosome attraction is driven by the condensation
of cytoplasmic RNA and Ki-67, a charged intrinsically disordered protein that
coats the chromosomes as a brush. Attraction between chromosomes has been shown
to be specifically promoted by a localized charged patch on Ki-67, although the
physical mechanism remains unclear. To elucidate this process, we combine coarse-grained
simulations and analytical theory to study the RNA-mediated interaction between
charged polymer brushes on the chromosome surfaces. We show that the charged patch
on Ki-67 leads to interchromosome attraction via RNA bridging between the two
brushes, whereby the RNA preferentially interacts with the charged patches, leading
to stable, long-range forces. By contrast, if the brush is uniformly charged,
bridging is basically absent due to complete adsorption of RNA onto the brush.
Moreover, the RNA dynamics becomes caged in presence of the charged patch while
remaining diffusive with uniform charge. Our work sheds light on the physical
origin of chromosome clustering, while also suggesting a general mechanism for
cells to tune work production by biomolecular condensates via different charge
distributions.

text: 'The migration behavior of colliding cells is critically determined by transient
contact interactions. During these interactions, the motility machinery, including
the front-rear polarization of the cell, dynamically responds to surface protein-mediated
transmission of forces and biochemical signals between cells. While biomolecular
details of such contact interactions are increasingly well understood, it remains
unclear what biophysical interaction mechanisms govern the cell-level dynamics
of colliding cells and how these mechanisms vary across cell types. Here we develop
a phenomenological theory based on 14 candidate contact-interaction mechanisms
coupling cell position, protrusion, and polarity. Using high-throughput micropattern
experiments, we detect which of these phenomenological contact interactions captures
the interaction behaviors of cells. We find that various cell types—ranging from
mesenchymal to epithelial cells—are accurately captured by a single model with
only two interaction mechanisms: polarity-protrusion coupling and polarity-polarity
coupling. Remarkably, the qualitatively different interaction behaviors of distinct
cells, as well as cells subject to molecular perturbations of surface protein-mediated
signaling, can all be quantitatively captured by varying the strength and sign
of the polarity-polarity coupling mechanism. Altogether, our data-driven phenomenological
theory of cell-cell interactions reveals polarity-polarity coupling as a versatile
and general contact-interaction mechanism, which may underlie diverse collective
migration behaviors of motile cells.'

text: Intelligent soft matter lies at the intersection of materials science, physics,
and cognitive science, promising to change how we design and interact with materials.
This transformative field aims to create materials with life-like capabilities,
such as perception, learning, memory, and adaptive behavior. Unlike traditional
materials, which typically perform static or predefined functions, intelligent
soft matter can dynamically interact with its environment, integrating multiple
sensory inputs, retaining past experiences, and making decisions to optimize its
responses. Inspired by biological systems, these materials leverage the inherent
properties of soft matter such as flexibility, adaptability, and responsiveness
to perform functions that mimic cognitive processes. By synthesizing current research
trends and projecting their evolution, we present a forward-looking perspective
on how intelligent soft matter could be constructed, with the aim of inspiring
innovations in areas such as biomedical devices, adaptive robotics, and beyond.
We highlight new pathways for integrating sensing, memory and actuation with low-power
internal operations, and we discuss key challenges in realizing materials that
exhibit truly “intelligent behavior”. These approaches outline a path toward more
robust, versatile, and scalable materials that can potentially act, compute, and
“think” through their inherent intrinsic material properties—moving beyond traditional
smart technologies that rely on external control.

text: White dwarfs (WDs) showing transits from orbiting planetary debris provide
significant insights into the structure and dynamics of debris disks, which are
eventually accreted to produce metal pollution. This is a rare class of objects
with only eight published systems. In this work, we perform a systematic search
for such systems within 500 pc in the Gaia-eDR3 catalog of WDs using the light
curves from the Zwicky Transient Facility (ZTF) and present six new candidates.
Our selection process targets the top 1% most photometrically variable sources
identified using a combined variability metric from ZTF and Gaia eDR3 photometry,
boosted by a metric space we define using von Neumann statistics and Pearson-Skew
as a novel discovery tool to identify these systems. This is followed by optical
spectroscopic observations of visually selected variables to confirm metal pollution.
Four of the six systems show long-timescale photometric variability spanning several
months to years, resulting either from long-term evolution of transit activity
or dust and debris clouds at wide orbits. Among them, WD J1013–0427 shows an indication
of reddening during the long-duration dip. Interpreting this as dust extinction
makes it the first system to indicate an abundance of dust grains with radius
≲0.3 μm in the occulting material. The same object also shows metal emission lines
that map an optically thick eccentric gas disk orbiting within the star’s Roche
limit. For each candidate, we infer the abundances of the photospheric metals
and estimate accretion rates. We show that transiting debris systems tend to have
higher inferred accretion rates compared to the general population of metal-polluted
WDs. Growing the number of these systems will further illuminate such comparative
properties in the near future. Separately, we also serendipitously discovered
an AM Canis Venaticorum showing a very long-duration outburst—only the fourth
such system to be known.

text: Widely deployed consensus protocols in the cloud are often leader-based and
optimized for low latency under synchronous network conditions. However, cloud
networks can experience disruptions such as network partitions, high-loss links,
and configuration errors. These disruptions interfere with the operation of leader-based
protocols, as their view change mechanisms interrupt the normal case replication
and cause the system to stall. We propose RACS, a novel randomized consensus protocol
that ensures robustness against adversarial network conditions. RACS achieves
optimal one-round trip latency under synchronous network conditions while remaining
resilient to adversarial network conditions. RACS follows a simple design inspired
by Raft, the most widely used consensus protocol in the cloud, and therefore enables
seamless integration with the existing cloud software stack. Experiments with
a prototype running on Amazon EC2 show that RACS achieves 28k cmd/sec throughput,
ninefold higher than Raft under adversarial cloud network conditions. Under synchronous
network conditions, RACS matches the performance of Multi-Paxos and Raft, achieving
a throughput of 200k cmd/sec with a median latency of 300ms, confirming that RACS
introduces no unnecessary overhead. Finally, SADL-RACS, a throughput-optimized
version of RACS, achieves a throughput of 500k cmd/sec, delivering 150 percent
higher throughput than Raft.

text: 'Given a family of varieties over the projective line, we study the density
of fibres that are everywhere locally soluble in the case that components of higher
multiplicity are allowed. We use log geometry to formulate a new sparsity criterion
for the existence of everywhere locally soluble fibres and formulate new conjectures
that generalise previous work of Loughran and Smeets. These conjectures involve
geometric invariants of the associated multiplicity orbifolds on the base of the
fibration in the spirit of Campana. We give evidence for the conjectures by providing
an assortment of bounds using Chebotarev’s theorem and sieve methods, with most
of the evidence involving upper bounds. '

text: Flickering light is a new promising, fully non-invasive brain stimulation
technique that utilizes intermittent sensory stimulation to induce brainwave synchronization
(entrainment). While the effects of 40 Hz externally induced neural entrainment
have been extensively described, little is known about 60 Hz entrainment in humans.
This study presents preliminary observations on the neural and somatic response
to flickering 60 Hz light in healthy volunteers over a 3-week period. Fourteen
volunteers were randomized to receive either 60 Hz flickering white light or constant
light as sham (30-min sessions, 3 weeks, 5 days/week on weekdays). Neural entrainment
was assessed with EEG on days 1, 5 and 19. Salivary cortisol and C-reactive protein
(CRP) levels, measured with ELISA, assessed the somatic response to stimulation.
Side effects and well-being were monitored via questionnaires. EEG recordings
showed neural entrainment and synchrony in response to 60 Hz flickering light
across multiple cortical regions, including occipital, central, temporal, and
frontal areas. The entrainment power and synchronization between different cortical
regions declined significantly by day 19 compared to day 1, indicating possible
neural habituation. Cortisol and CRP salivary levels were unchanged, and minor
side effects were reported with equal frequency in the active and sham groups.
Our findings show that 60 Hz flickering light can induce significant neural entrainment
and synchrony in healthy adults and is well tolerated. The decline in entrainment
strength and neural synchrony observed with repeated 60 Hz stimulations suggests
plastic changes in the cortex. To the best of our knowledge, this is the first
study to characterize neural and somatic responses to repeated 60 Hz flickering
visual stimuli. Given the well-known connection between 60 Hz brain oscillations
and cognition, neuroplasticity, and their role in neuropsychiatric disorders,
additional research in both preclinical and clinical settings is warranted.

text: Stellar astrophysics relies on diverse observational modalities—primarily
photometric light curves and spectroscopic data—from which fundamental stellar
properties are inferred. While machine learning (ML) has advanced analysis within
individual modalities, the complementary information encoded across modalities
remains largely underexploited. We present the dual embedding for stellar astronomy
(DESA) model, a novel multimodal foundation model that integrates light curves
and spectra to learn a unified, physically meaningful latent space for stars.
DESA first trains separate modality-specific encoders using a hybrid supervised/self-supervised
scheme, and then aligns them through DualFormer, a transformer-based cross-modal
integration module tailored for astrophysical data. DualFormer combines cross-
and self-attention, a novel dual-projection alignment loss, and a projection-space
eigendecomposition that yields physically structured embeddings. We demonstrate
that DESA significantly outperforms leading unimodal and self-supervised baselines
across a range of tasks. In zero- and few-shot settings, DESA’s learned representations
recover stellar color–magnitude and Hertzsprung–Russell diagrams with high fidelity
(R2 = 0.92 for photometric regressions). In full fine-tuning, DESA achieves state-of-the-art
accuracy for binary star detection (AUC = 0.99, AP = 1.00) and stellar age prediction
(RMSE = 0.94 Gyr). As a compelling case, DESA naturally separates synchronized
binaries from young stars—two populations with nearly identical light curves—purely
from their embedded positions in UMAP space, without requiring external kinematic
or luminosity information. DESA thus offers a powerful new framework for multimodal,
data-driven stellar population analysis, enabling both accurate prediction and
novel discovery.

text: Seasonal snowmelt in High Mountain Asia is an important source of river discharge.
Therefore, observation of the spatiotemporal variations in snow cover at catchment
scales using high-resolution satellites is essential for understanding changes
in water supply from headwater catchments. In this study, we adapt an algorithm
to automatically detect the snowline altitude (SLA) using the Google Earth Engine
platform with available high-resolution multispectral satellite archives that
can be readily applied for areas of interest. Here, we applied and evaluated the
tool to five glacierized watersheds across the Himalayas to quantify the changes
in seasonal and annual snow cover over the past 21 years and analyze climate reanalysis
data to assess the meteorological factors influencing the SLA. Our findings revealed
substantial variations in the SLA among sites in terms of seasonal patterns, decadal
trends, and meteorological controls. We identify positive trends in SLA in Hidden
Valley (+11.9 m yr−1), Langtang (+14.4 m yr−1), and Rolwaling (+8.2 m yr−1) in
the Nepalese Himalayas but a negative trend in Satopanth (−15.6 m yr−1) in the
western Indian Himalayas and no significant trend in Parlung in southeastern Tibet.
We suggest that the increase in SLA in Nepal was caused by warmer temperatures
during the monsoon season, whereas the decrease in SLA in India was driven by
increased winter snowfall and reduced monsoon snowmelt. By integrating the outcomes
of these analyses, we found that long-term changes in SLA are primarily driven
by shifts in the local climate, whereas seasonal variability may be influenced
by geographic features in conjunction with climate.

text: Camera-type eyes in vertebrates and cephalopods are striking examples of parallel
evolution of a complex structure. While comparisons have focused on these two
groups, camera-type eyes with likely high functionality are also found in other
invertebrate phyla with simpler brains. Employing single-cell RNA sequencing,
we identify neurogenic cells in the adult eyes and brain of the marine annelid
worm Platynereis dumerilii. Distinct neural stem cells in the camera-type adult
eyes, located at the edge of the cup-shaped retina, and adjacent to the glass
body/lens, produce radial lines of cells, reminiscent of stem cells in ciliary
marginal zones of vertebrate eyes exhibiting life-long growth. Normal proliferation
in the eye depends on ambient light, a phenomenon that depends on the integrity
of the photoreceptor gene c-opsin1, which is present in emerging rhabdomeric photoreceptors,
and impacts on their differentiation. During reproductive maturation, proliferation
in the eye as well as the entire brain sharply declines, while cells upregulate
molecular characteristics of mammalian adult neural stem cell quiescence. Our
data provide insights into the development and modulation of annelid head and
brain cells, revealing similarities and differences to vertebrate eye development,
neurogenesis and brain plasticity.

text: We investigate the step complexity of the Leader Election problem (and implementing
the corresponding test-and-set object) in asynchronous shared memory, where processes
communicate through registers supporting atomic read and write and must coordinate
so that a single process becomes the leader. Determining tight step complexity
bounds for solving this problem is one of the key open problems in the theory
of shared memory distributed computing. The best known algorithm is a randomized
tournament-tree, which has worst-case expected step complexity O(log N) for N
processes. There are provably no deterministic wait-free algorithms, and only
restricted lower bounds are known for obstruction-free and randomized wait-free
algorithms. We introduce a new lower bound that establishes an Ω((log N)/(log
log N + log Q)) step complexity for any obstruction-free Leader Election algorithm,
where N is the number of processes, and 2 ≤ Q ≤ N is a bound on the value contention,
which we define as the maximum number of different values that processes can be
simultaneously poised to write to the same register in any execution of the algorithm.
Our result is strictly stronger than previous bounds based on write contention.
In particular, it implies new lower bounds on step complexity that depend on register
size.

text: Cellular membranes differ across the tree of life. In most bacteria and eukaryotes,
single-headed lipids self-assemble into flexible bilayer membranes. By contrast,
thermophilic archaea tend to possess bilayer lipids together with double-headed,
monolayer spanning bolalipids, which are thought to enable cells to survive in
harsh environments. Here, using a minimal computational model for bolalipid membranes,
we explore the trade-offs at play when forming membranes. We find that flexible
bolalipids form membranes that resemble bilayer membranes because they are able
to assume a U-shaped conformation. Conversely, rigid bolalipids, which resemble
the bolalipids with cyclic groups found in thermophilic archaea, take on a straight
conformation and form membranes that are stiff and prone to pore formation when
they undergo changes in shape. Strikingly, however, the inclusion of small amounts
of bilayer lipids in a bolalipid membrane is enough to achieve fluid bolalipid
membranes that are both stable and flexible, resolving this trade-off. Our study
suggests a mechanism by which archaea can tune the material properties of their
membranes as and when required to enable them to survive in harsh environments
and to undergo essential membrane remodelling events like cell division.
