text: New populations of red active galactic nuclei (known as “little red dots”)
discovered by JWST exhibit remarkable spectral energy distributions. Leveraging
X-ray through far-infrared observations of two of the most luminous known little
red dots, we directly measure their bolometric luminosities. We find evidence
that more than half of the bolometric luminosity likely emerges in the rest-frame
optical, with Lbol/L5100 = 5, roughly half the value for “standard” active galactic
nuclei. Meanwhile, the X-ray emitting corona, UV-emitting blackbody, and reprocessed
mid to far-infrared emission are all considerably subdominant, assuming that the
far-infrared luminosity is well below current measured limits. We present new
bolometric corrections that dramatically lower inferred bolometric luminosities
by a factor of 10 compared to published values in the literature. These bolometric
corrections are in accord with expectations from models in which gas absorption
and reprocessing are responsible for the red rest-frame optical colors of little
red dots. We discuss how this lowered luminosity scale suggests a lower mass scale
for the population by at least an order of magnitude (e.g., ∼105–107 M⊙ black
holes, and ∼108 M⊙ galaxies), alleviating tensions with clustering, overmassive
black holes, and the integrated black hole mass density in the Universe.

text: Robust Markov Decision Processes (RMDPs) generalize classical MDPs that consider
uncertainties in transition probabilities by defining a set of possible transition
functions. An objective is a set of runs (or infinite trajectories) of the RMDP,
and the value for an objective is the maximal probability that the agent can guarantee
against the adversarial environment. We consider (a) reachability objectives,
where given a target set of states, the goal is to eventually arrive at one of
them; and (b) parity objectives, which are a canonical representation for ω-regular
objectives. The qualitative analysis problem asks whether the objective can be
ensured with probability 1. In this work, we study the qualitative problem for
reachability and parity objectives on RMDPs without making any assumption over
the structures of the RMDPs, e.g., unichain or aperiodic. Our contributions are
twofold. We first present efficient algorithms with oracle access to uncertainty
sets that solve qualitative problems of reachability and parity objectives. We
then report experimental results demonstrating the effectiveness of our oracle-based
approach on classical RMDP examples from the literature scaling up to thousands
of states.

text: "In this paper, we consider the big algebra recently introduced by Hausel
for the GLn-action on the coordinate ring of the matrix space Mat(n,r). In particular,
we obtain explicit formulas for the big algebra generators in terms of differential
operators with polynomial coefficients. We show that big algebras in type A are
commutative and relate them to the Bethe subalgebra in the Yangian Y(gln). We
apply these results to big algebras of symmetric powers of the standard representation
of GLn.\r\n."

text: "We develop a new algorithmic framework for designing approximation algorithms
for cut-based optimization problems on capacitated undirected graphs that undergo
edge insertions and deletions. Specifically, our framework dynamically maintains
a variant of the hierarchical \U0001D457-tree decomposition of [Madry FOCS’10],
achieving a poly-logarithmic approximation factor to the graph’s cut structure
and supporting edge updates in \U0001D442(\U0001D45B\U0001D700) amortized update
time, for any arbitrarily small constant \U0001D700 ∈(0,1).\r\nConsequently, we
obtain new trade-offs between approximation and update/query time for fundamental
cut-based optimization problems in the fully dynamic setting, including all-pairs
minimum cuts, sparsest cut, multi-way cut, and multi-cut. For the last three problems,
these trade-offs give the first fully-dynamic algorithms achieving poly-logarithmic
approximation in sub-linear time per operation.\r\nThe main technical ingredient
behind our dynamic hierarchy is a dynamic cut-sparsifier algorithm that can handle
vertex splits with low recourse. This is achieved by white-boxing the dynamic
cut sparsifier construction of [Abraham et al. FOCS’16], based on forest packing,
together with new structural insights about the maintenance of these forests under
vertex splits. Given the versatility of cut sparsification in both the static
and dynamic graph algorithms literature, we believe this construction may be of
independent interest."

text: 'Partially observable Markov decision processes (POMDPs) are a central model
for uncertainty in sequential decision making. The most basic objective is the
reachability objective, where a target set must be eventually visited, and the
more general parity objectives can model all omega-regular specifications. For
such objectives, the computational analysis problems are the following: (a) qualitative
analysis that asks whether the objective can be satisfied with probability 1 (almost-sure
winning) or probability arbitrarily close to 1 (limit-sure winning); and (b) quantitative
analysis that asks for the approximation of the optimal probability of satisfying
the objective. For general POMDPs, almost-sure analysis for reachability objectives
is EXPTIME-complete, but limit-sure and quantitative analyses for reachability
objectives are undecidable; almost-sure, limit-sure, and quantitative analyses
for parity objectives are all undecidable. A special class of POMDPs, called revealing
POMDPs, has been studied recently in several works, and for this subclass the
almost-sure analysis for parity objectives was shown to be EXPTIME-complete. In
this work, we show that for revealing POMDPs the limit-sure analysis for parity
objectives is EXPTIME-complete, and even the quantitative analysis for parity
objectives can be achieved in EXPTIME.'

text: "The initial–final mass relation (IFMR) links a star’s birth mass to the mass
of its white dwarf (WD) remnant, providing key constraints on stellar evolution.
Open clusters offer the most straightforward way to empirically determine the
IFMR, as their well-defined ages allow for direct progenitor lifetime estimates.
We construct the most comprehensive open cluster WD IFMR to date by combining
new spectroscopy of 22 WDs with an extensive literature review of WDs with strong
cluster associations. To minimize systematics, we restrict our analysis to spectroscopically
confirmed hydrogen-atmosphere (DA) WDs consistent with single-stellar origins.
We separately analyze a subset with reliable Gaia-based astrometric membership
assessments, as well as a full sample that adds WDs with strong cluster associations
whose membership cannot be reliably assessed with Gaia. The Gaia-based sample
includes 69 spectroscopically confirmed DA WDs, more than doubling the sample
size of previous Gaia-based open cluster IFMRs. The full sample, which includes
53 additional literature WDs,\r\nincreases the total number of cluster WDs by
over 50% relative to earlier works. We provide functional forms for both the Gaia-based
and full-sample IFMRs. The Gaia-based result useful for Mi � 2.67 M⊙ is Mf = [0.179
0.100H (Mi 3.84 M )] × (Mi 3.84 M ) + 0.628 M , where H(x) is the Heaviside step
function. Comparing our IFMR to recent literature, we identify significant deviations
from best-fit IFMRs derived from both Gaia-based volume-limited samples of field
WDs and double WD binaries, with the largest discrepancy occurring for initial
masses of about 5 M⊙."

text: In calculus, l'Hopital's rule provides a simple way to evaluate the limits
of quotient functions when both the numerator and denominator vanish. But what
happens when we move beyond real functions on a real interval? In this article,
we study when the quotient of two complex-valued functions in higher dimension
can be defined continuously at the points where both functions vanish. Surprisingly,
the answer is far subtler than in the real-valued setting. We provide a complete
characterization for the continuity of the quotient function. We also point out
why extending this result to smoother quotients remains an intriguing challenge.

text: We present symplectic structures on the shape space of unparameterized space
curves that generalize the classical Marsden–Weinstein structure. Our method integrates
the Liouville 1-form of the Marsden–Weinstein structure with Riemannian structures
that have been introduced in mathematical shape analysis. We also derive Hamiltonian
vector fields for several classical Hamiltonian functions with respect to these
new symplectic structures.

text: The paraventricular hypothalamus (PVH) controls behavioral and physiologic
processes, including appetite, social behavior, autonomic outflow, and pituitary
hormone secretion. However, molecular markers for centrally projecting PVH neuron
populations remain largely undefined, and a complete census of PVH cell types
has not been established. Therefore, we performed extensive single-cell/nucleus
RNA sequencing to catalog PVH neuron subtypes and multiplexed error-robust fluorescence
in situ hybridization (MERFISH) to map them spatially. Our spatial transcriptomic
atlas resolves 26 Sim1+ and 29 GABAergic neuron populations from the PVH and surrounding
areas. Additionally, projection-based profiling identified neurons that project
to the parabrachial region (PB) and spinal cord, helping to determine PVH populations
that regulate satiety and sympathetic nervous system activity, respectively. Notably,
activation of PB-projecting PVH neurons expressing Brs3 reduces food intake, and
silencing them causes obesity. Together, this atlas contributes high-resolution
PVH spatial and circuit-based gene expression profiles, representing a valuable
resource for the field of homeostasis.

text: 'The small DAHe and DAe spectral classes comprise isolated, hydrogen-dominated
atmosphere white dwarfs that exhibit variable photometric flux and Balmer line
emission. These mysterious systems offer unique insight into the complex interplay
between magnetic fields, stellar rotation and atmospheric activity in single white
dwarfs. DAHe stars have detectable magnetic fields through Zeeman-split spectral
lines, whereas DAe stars lack such splitting. We report the first discovery and
characterization of magnetism in the DAe white dwarf WD J165335.21−100116.33 with
new time-resolved spectropolarimetry from FORS2. We detect a weak but variable
longitudinal magnetic field with values Bz > −9.2 ± 2.4 kG and Bz < −2.2 ± 1.0
kG. Independent ZTF and ATLAS photometry reveal a consistent period of P = 80.3070
± 0.0007 h. Time-resolved optical spectroscopy obtained with six ground-based
instruments demonstrates strong modulation in the strength of the Hα and Hβ Balmer
line emission with P = 80.2922 ± 0.0108 h. The photometric flux and Balmer emission
strength vary in antiphase, with the strongest magnetic detections coinciding
with phases of low photometric flux and strong line emission. These characteristicssupport
the theory that a magnetically active, temperature-inverted spot/region is producing
an optically thin chromospheric emission region. Comparison with other DAe and
DAHe white dwarfsreveals all systems have a strikingly similar antiphase phenomenology,
reinforcing the theory that they are subject to a unified physical mechanism.
With the detection of a weak magnetic field, we reclassify WD J165335.21−100116.33
as a low-field DAHe white dwarf. '

text: Entanglement does not always require one particle per party. It was predicted
some 30 years ago that a single photon traversing a beam splitter could violate
a Bell inequality. Although initially debated, single-photon nonlocality was eventually
demonstrated via homodyne measurements. Here, we present an alternate realization
that avoids the complexity of homodyne measurements and potential loopholes in
their implementation. We violate a Bell inequality by performing joint measurements
on two copies of the same single-photon entangled state, where one photon acts
as a phase reference for the other, making it self-referential. We observe CHSH
parameters of 2.71 = 0.09 and 2.23 = 0.07, depending on the joint measurements
implemented. This offers a perspective on single-photon nonlocality and a more
accessible experimental route, potentially applicable to general mode-entangled
states in diverse platforms.

text: Cells are defined by lipid membranes that differ in their structure across
the tree of life. While the membranes of most bacteria and eukaryotes consist
of single-headed bilayer lipids, the membranes of archaea are composed of mixtures
of single-headed bilayer lipids and double-headed bolalipids. Archaeal bolalipids
can adopt straight or u-shaped conformations, enabling them—together with bilayer
lipids—to control whether membranes form bilayer or monolayer structures. Yet,
the physical principles governing archaeal membranes remain largely unexplored,
especially how membrane structure couples to externally imposed curvature during
membrane remodeling. Here, we perform coarse-grained molecular dynamics simulations
of toroidal vesicles to systematically probe the effects of all relevant combinations
of mean and Gaussian curvatures on shape stability and lipid organization. We
find that soft bilayer membranes can sustain all curvatures induced, whereas rigid
bolalipid monolayer membranes either transition to different vesicle shapes or
rupture. Bilayer-mimicking u-shaped bolalipids and bilayer lipids are spatially
accumulated in regions of high mean membrane curvature independent of Gaussian
curvature. Our work identifies curvature–composition coupling as a physical signature
of archaeal membrane remodeling.

text: The collagen triple helix assembles hierarchically into bundled oligomers,
solvated networks, and fibers. Synthetic peptide assemblies, driven by supramolecular
interactions, can form single triple helices through intrahelical amino acid pairs;
however, the principles guiding interhelical associations into higher-order structures
remain unclear. Here, we incorporate cation−π and electrostatic charge pairs to
probe interhelical interactions and elucidate the mechanisms driving triple helix
assembly into fibrils, nanotubes, and nanosheets. Introducing cation−π pairs into
a fibrillating collagen mimetic resulted in D-periodic fibrils with pH-sensitive
gelation. By alternating the presentation of electrostatic and cation−π pairs,
the assembly of another D-periodic fibril featuring inner and outer triple-helical
layers was resolved by cryo electron microscopy to a resolution of 8 Å. At physiological
pH, antiparallel association of these triple helices leads to the formation of
nanotubes. The packing behavior of triple helices correlates with the interhelical
interactions, where parallel associations favor fibril formation and antiparallel
interactions drive nanotube and nanosheet assembly. These self-assembling triple-helical
peptides demonstrate how packing of higher-order structures can be tailored with
supramolecular interactions and establish the relationship of different hierarchical
collagen-mimetic assemblies as pH-dependent.

text: Liquid-like superionic conductors, with highly mobile ions in a rigid framework,
offer intrinsically low lattice thermal conductivity without compromising electronic
transport. Argyrodite-type Ag8SnSe6 exhibits a melt-like Ag sublattice that drives
lattice thermal conductivity (κL) below 0.2 watts per meter per kelvin, yet its
low carrier concentration limits the power factor. Here, interstitial Ag atoms
raise the Fermi level into the conduction band, substantially increasing the electron
concentration. Simultaneously, the formation of a secondary Ag2Se phase generates
lattice distortions that enhance phonon scattering. A pronounced mismatch between
electronic (~200 nanometers) and phononic (~0.22 nanometers) mean free paths decouples
charge and heat transport, enabling concurrent suppression of κL and retention
of high electrical conductivity. This coupled electronic-phononic modulation yields
a record ZT of 0.72 at ambient temperature and a peak ZT of 1.1 at 735 kelvins,
with an average ZTavg of 0.72 over 320 to 735 kelvins. A unicouple device achieves
6.3% efficiency under a 357-kelvin gradient, highlighting a practical strategy
for high-performance midtemperature thermoelectrics.

text: Epithelial tissues function as multicellular communities that preserve tissue
integrity while adapting to diverse environmental stresses by altering cell behaviors.
A striking manifestation of such adaptability is cell plasticity, the ability
of differentiated cells to revert to stem-like states or adopt alternative fates.
Once considered rare and confined to highly regenerative species, cell plasticity
is now recognized across the metazoan tree. In early-branching animals such as
sponges and cnidarians, transdifferentiation and dedifferentiation are integral
to life-cycle transitions and regeneration, whereas in more complex organisms,
these processes typically emerge under stress, including stem cell loss or environmental
perturbations. Here, we examine epithelial cell plasticity through evolutionary,
cellular, and molecular perspectives. Focusing on the intestinal epithelium, we
explore findings from mammalian and Drosophila models showing that progenitors
and even terminally differentiated cells can dedifferentiate in response to external
stimuli that disrupt homeostasis, such as pathogen infection and nutrient fluctuations.
We further discuss conserved mechanisms involving intercellular signaling (e.g.,
Notch, EGFR, and JAK-STAT) and chromatin states primed for reprogramming, modulated
by metabolic cues. Together, these insights position cell plasticity as an ancient
environmental adaptation strategy, shaped by conserved molecular toolkits and
refined by species- and cell lineage-specific innovations.

text: The origin(s) of life (OoL), which has puzzled scientists for centuries, remains
a major scientific challenge in the 21st century. Understanding the processes
relevant to the OoL demands theoretical frameworks that can connect processes
across scales, from microscopic dynamics to emergent levels of organization. While
experimental studies generate a wealth of data, theoretical and computational
approaches provide the structure necessary to interpret and generalize these findings.
In Part 1, we examined the most widely used experimental techniques in the field.
Here, we focus on the mathematical, physical, and computational techniques used
to model phenomena relevant to life’s origin(s). We discuss methods ranging from
quantum chemistry and molecular dynamics to chemical reaction networks, autocatalysis,
and evolutionary modeling, as well as information-theoretic and phylogenetic approaches
that link chemical and biological organization. We further highlight emerging
trends such as synthetic biology, omics-based methods, and laboratory automation
as novel points of contact for theory-experiment integration. Ultimately, we aim
to provide an educational tool that can facilitate more post-disciplinary collaborations
in OoL research by helping scientists understand what they can do about the problem
of life’s origins, rather than telling them how to think about it.

text: The origin(s) of life (OoL), which has puzzled scientists for centuries, remains
a major scientific challenge in the 21st century. Research on OoL spans many disciplines,
including chemistry, physics, biology, planetary sciences, computer science, and
mathematics. The sheer number of different scientific perspectives relevant to
the problem has resulted in the coexistence of diverse tools, techniques, data,
and software in OoL studies. This has made communication between the disciplines
relevant to the OoL extremely difficult because the interpretation of data, analyses,
or standards of evidence varies dramatically. Here, we hope to bridge this wide
field of study by providing common ground via the consolidation of techniques
rather than positing a unifying view on how life emerges. In part 1 of this review,
we cover common experimental techniques that have been used significantly in OoL
studies in recent years, while in part 2, we review theoretical, computational,
and integrative methods. Here, we discuss the use of spectroscopy, spectrometry,
chromatography, microscopy, and sequencing methods for characterizing diverse
materials. We further discuss the role of data repositories in facilitating the
analysis and dissemination of experimental data. This review provides a baseline
expectation and understanding of the analytical aspects of origins’ research.
Ultimately, we aim to provide an educational tool that can facilitate more post-disciplinary
collaborations in OoL research by helping scientists understand what they can
do about the problem of life’s origins, rather than telling them how to think
about it.

text: Tropical shallow clouds are a major source of uncertainty in Earth's climate
sensitivity, especially through their spatial arrangement, which global climate
models do not represent. Efforts to understand their organization have partly
relied on classifying observed scenes, identifying four patterns as archetypal
regimes. Here we analyze geostationary satellite imagery of the western tropical
Atlantic using the L‐function, a tool based on point pattern theory that quantifies
cloud organization across spatial scales. Classical examples of the four patterns
show distinct L‐function fingerprints, revealing their characteristic clustering
and regularity scales and aiding physical interpretation. Yet, when evaluating
many scenes at fixed spatial scales, the L‐function distribution lacks the distinct
modes expected from discrete regimes. This is corroborated by analyses of other
organization indices employing diverse approaches, from inter‐cloud nearest‐neighbor
distances to fractal analysis. Implications for the parameterization of mesoscale
cloud organization in climate models are discussed.

text: 3I/ATLAS is the third interstellar object discovered to date, following 1I/‘Oumuamua
and 2I/Borisov. Its unusually high excess velocity and active cometary nature
make it a key probe of the Galactic population of icy planetesimals. Understanding
its origin requires its past trajectory through the Galaxy to be traced and the
possible role of stellar encounters to be assessed, both as a potential origin
and a perturber to its orbit. We integrated the orbit of 3I/ATLAS backward in
time for 10 Myr, together with a sample of Gaia DR3 stars with high-quality astrometry
and radial velocities, to identify close passages within 2 pc. We identify 93
nominal encounters, 62 of which are significant at the 2σ level. However, none
of these encounters produced any meaningful perturbation. The strongest perturber
Gaia DR3 6863591389529611264 at 0.30 pc and with a relative velocity of 35 km
s−1, imparted only a velocity change of ∣Δv∣ ≃ 5 × 10−4 km s−1 to the orbit
of 3I/ATLAS. Our results indicate that no stellar flybys within the past 10 Myr
and 500 pc contained in Gaia DR3 can account for the present trajectory of 3I/ATLAS
or be associated with its origin. We further show that 3I/ATLAS is kinematically
consistent with a thin-disk population, despite its large peculiar velocity.

text: Neural tube closure is a critical morphogenetic process in vertebrate development,
and failure to close cranial regions such as the hindbrain neuropore (HNP) leads
to severe congenital malformations. While mechanical forces such as actomyosin
purse-string contraction and directional cell crawling have been implicated in
driving HNP closure, how these forces organize local cell shape and motion to
produce large-scale tissue remodeling remains poorly understood. Using live and
fixed imaging of mouse embryos combined with cell-based biophysical modeling,
we show that these force-generating mechanisms are insufficient to explain the
reproducible patterns of cell elongation and nematic alignment observed at the
HNP border. Instead, we show that local anisotropic stress and cytoskeletal organization
are required to generate these patterns and promote midline cell motion. Our model
captures key features of cell shape dynamics and emergent nematic order, which
we confirm experimentally, including the alignment of actin fibers with cell shape
and enhanced midline cell speed. Comparative analysis with chick embryos, which
lack supracellular purse strings, supports a conserved link between tension generation
and cellular patterning. These findings establish a physical framework connecting
force generation, cell shape anisotropy, and tissue morphodynamics during epithelial
gap closure.
