text: "We investigate fast and communication-efficient algorithms for the classic
problem of minimizing a sum of strongly convex and smooth functions that are distributed
among n\r\n different nodes, which can communicate using a limited number of bits.
Most previous communication-efficient approaches for this problem are limited
to first-order optimization, and therefore have \\emph{linear} dependence on the
condition number in their communication complexity. We show that this dependence
is not inherent: communication-efficient methods can in fact have sublinear dependence
on the condition number. For this, we design and analyze the first communication-efficient
distributed variants of preconditioned gradient descent for Generalized Linear
Models, and for Newton’s method. Our results rely on a new technique for quantizing
both the preconditioner and the descent direction at each step of the algorithms,
while controlling their convergence rate. We also validate our findings experimentally,
showing faster convergence and reduced communication relative to previous methods."

text: 'Self-assembly of nanoparticles can be mediated by polymers, but has so far
led almost exclusively to nanoparticle aggregates that are amorphous. Here, we
employed Coulombic interactions to generate a range of composite materials from
mixtures of charged nanoparticles and oppositely charged polymers. The assembly
behavior of these nanoparticle/polymer composites depends on their order of addition:
polymers added to nanoparticles give rise to stable aggregates, but nanoparticles
added to polymers disassemble the initially formed aggregates. The amorphous aggregates
were transformed into crystalline ones by transiently increasing the ionic strength
of the solution. The morphology of the resulting crystals depended on the length
of the polymer: short polymer chains mediated the self-assembly of nanoparticles
into strongly faceted crystals, whereas long chains led to pseudospherical nanoparticle/polymer
assemblies, within which the crystalline order of nanoparticles was retained.'

text: Coulombic interactions can be used to assemble charged nanoparticles into
higher-order structures, but the process requires oppositely charged partners
that are similarly sized. The ability to mediate the assembly of such charged
nanoparticles using structurally simple small molecules would greatly facilitate
the fabrication of nanostructured materials and harnessing their applications
in catalysis, sensing and photonics. Here we show that small molecules with as
few as three electric charges can effectively induce attractive interactions between
oppositely charged nanoparticles in water. These interactions can guide the assembly
of charged nanoparticles into colloidal crystals of a quality previously only
thought to result from their co-crystallization with oppositely charged nanoparticles
of a similar size. Transient nanoparticle assemblies can be generated using positively
charged nanoparticles and multiply charged anions that are enzymatically hydrolysed
into mono- and/or dianions. Our findings demonstrate an approach for the facile
fabrication, manipulation and further investigation of static and dynamic nanostructured
materials in aqueous environments.

text: DNA nanotechnology offers a versatile toolbox for precise spatial and temporal
manipulation of matter on the nanoscale. However, rendering DNA-based systems
responsive to light has remained challenging. Herein, we describe the remote manipulation
of native (non-photoresponsive) chiral plasmonic molecules (CPMs) using light.
Our strategy is based on the use of a photoresponsive medium comprising a merocyanine-based
photoacid. Upon exposure to visible light, the medium decreases its pH, inducing
the formation of DNA triplex links, leading to a spatial reconfiguration of the
CPMs. The process can be reversed simply by turning the light off and it can be
repeated for multiple cycles. The degree of the overall chirality change in an
ensemble of CPMs depends on the CPM fraction undergoing reconfiguration, which,
remarkably, depends on and can be tuned by the intensity of incident light. Such
a dynamic, remotely controlled system could aid in further advancing DNA-based
devices and nanomaterials.

text: Dissipative self-assembly is ubiquitous in nature, where it gives rise to
complex structures and functions such as self-healing, homeostasis, and camouflage.
These phenomena are enabled by the continuous conversion of energy stored in chemical
fuels, such as ATP. Over the past decade, an increasing number of synthetic chemically
driven systems have been reported that mimic the features of their natural counterparts.
At the same time, it has been shown that dissipative self-assembly can also be
fueled by light; these optically fueled systems have been developed in parallel
to the chemically fueled ones. In this perspective, we critically compare these
two classes of systems. Despite the complementarity and fundamental differences
between these two modes of dissipative self-assembly, our analysis reveals that
multiple analogies exist between chemically and light-fueled systems. We hope
that these considerations will facilitate further development of the field of
dissipative self-assembly.

text: Most massive stars are born in binaries close enough for mass transfer episodes.
These modify the appearance, structure, and future evolution of both stars. We
compute the evolution of a 100-day-period binary, consisting initially of a 25
M⊙ star and a 17 M⊙ star, which experiences stable mass transfer. We focus on
the impact of mass accretion on the surface composition, internal rotation, and
structure of the accretor. To anchor our models, we show that our accretor broadly
reproduces the properties of ζ Ophiuchi, which has long been proposed to have
accreted mass before being ejected as a runaway star when the companion exploded.
We compare our accretor to models of single rotating stars and find that the later
and stronger spin-up provided by mass accretion produces significant differences.
Specifically, the core of the accretor retains higher spin at the end of the main
sequence, and a convective layer develops that changes its density profile. Moreover,
the surface of the accretor star is polluted by CNO-processed material donated
by the companion. Our models show effects of mass accretion in binaries that are
not captured in single rotating stellar models. This possibly impacts the further
evolution (either in a binary or as single stars), the final collapse, and the
resulting spin of the compact object.

text: Helium star–carbon-oxygen white dwarf (CO WD) binaries are potential single-degenerate
progenitor systems of thermonuclear supernovae. Revisiting a set of binary evolution
calculations using the stellar evolution code MESA, we refine our previous predictions
about which systems can lead to a thermonuclear supernova and then characterize
the properties of the helium star donor at the time of explosion. We convert these
model properties to near-UV/optical magnitudes assuming a blackbody spectrum and
support this approach using a matched stellar atmosphere model. These models will
be valuable to compare with pre-explosion imaging for future supernovae, though
we emphasize the observational difficulty of detecting extremely blue companions.
The pre-explosion source detected in association with SN 2012Z has been interpreted
as a helium star binary containing an initially ultra-massive WD in a multiday
orbit. However, extending our binary models to initial CO WD masses of up to 1.2
M⊙, we find that these systems undergo off-center carbon ignitions and thus are
not expected to produce thermonuclear supernovae. This tension suggests that,
if SN 2012Z is associated with a helium star–WD binary, then the pre-explosion
optical light from the system must be significantly modified by the binary environment
and/or the WD does not have a carbon-rich interior composition.

text: The majority of massive stars live in binary or multiple systems and will
interact with a companion during their lifetimes, which helps to explain the observed
diversity of core-collapse supernovae. Donor stars in binary systems can lose
most of their hydrogen-rich envelopes through mass transfer. As a result, not
only are the surface properties affected, but so is the core structure. However,
most calculations of the core-collapse properties of massive stars rely on single-star
models. We present a systematic study of the difference between the pre-supernova
structures of single stars and stars of the same initial mass (11–21 M⊙) that
have been stripped due to stable post-main-sequence mass transfer at solar metallicity.
We present the pre-supernova core composition with novel diagrams that give an
intuitive representation of the isotope distribution. As shown in previous studies,
at the edge of the carbon-oxygen core, the binary-stripped star models contain
an extended gradient of carbon, oxygen, and neon. This layer remains until core
collapse and is more extended in mass for higher initial stellar masses. It originates
from the receding of the convective helium core during core helium burning in
binary-stripped stars, which does not occur in single-star models. We find that
this same evolutionary phase leads to systematic differences in the final density
and nuclear energy generation profiles. Binary-stripped star models have systematically
higher total masses of carbon at the moment of core collapse compared to single-star
models, which likely results in systematically different supernova yields. In
about half of our models, the silicon-burning and oxygen-rich layers merge after
core silicon burning. We discuss the implications of our findings for the “explodability”,
supernova observations, and nucleosynthesis of these stars. Our models are publicly
available and can be readily used as input for detailed supernova simulations.

text: While most simulations of the epoch of reionization have focused on single-stellar
populations in star-forming dwarf galaxies, products of binary evolution are expected
to significantly contribute to emissions of hydrogen-ionizing photons. Among these
products are stripped stars (or helium stars), which have their envelopes stripped
from interactions with binary companions, leaving an exposed helium core. Previous
work has suggested these stripped stars can dominate the Lyman Continuum (LyC)
photon output of high-redshift, low-luminosity galaxies post-starburst. Other
sources of hard radiation in the early universe include zero-metallicity Population
iii stars, which may have similar spectral energy distribution (SED) properties
to galaxies with radiation dominated by stripped-star emissions. Here, we use
four metrics (the power-law exponent over wavelength intervals 240–500 Å, 600–900
Å, and 1200–2000 Å, and the ratio of total luminosity in FUV wavelengths to LyC
wavelengths) to compare the SEDs of simulated galaxies with only single-stellar
evolution, galaxies containing stripped stars, and galaxies containing Population
iii stars, with four different initial mass functions (IMFs). We find that stripped
stars significantly alter SEDs in the LyC range of galaxies at the epoch of reionization.
SEDs in galaxies with stripped stars have lower power-law indices in the LyC range
and lower FUV to LyC luminosity ratios. These differences in SEDs are present
at all considered luminosities (${M}_{\mathrm{UV}}\gt -15$, AB system), and are
most pronounced for lower-luminosity galaxies. Intrinsic SEDs as well as those
with interstellar medium absorption of galaxies with stripped stars and Population
iii stars are found to be distinct for all tested Population iii IMFs.

text: "Context. Observations of massive stars in open clusters younger than ∼8 Myr
have shown that a majority of them are in binary systems, most of which will interact
during their life. While these can be used as a proxy of the initial multiplicity
properties, studying populations of massive stars older than ∼20 Myr allows us
to probe the outcome of these interactions after a significant number of systems
have experienced mass and angular momentum transfer and may even have merged.\r\n\r\nAims.
Using multi-epoch integral-field spectroscopy, we aim to investigate the multiplicity
properties of the massive-star population in the dense core of the ∼40 Myr old
cluster NGC 330 in the Small Magellanic Cloud in order to search for possible
imprints of stellar evolution on the multiplicity properties.\r\n\r\nMethods.
We obtained six epochs of VLT/MUSE observations operated in wide-field mode with
the extended wavelength setup and supported by adaptive optics. We extracted spectra
and measured radial velocities for stars brighter than mF814W = 19. We identified
single-lined spectroscopic binaries through significant RV variability with a
peak-to-peak amplitude larger than 20 km s−1. We also identified double-lined
spectroscopic binaries, and quantified the observational biases for binary detection.
In particular, we took into account that binary systems with similar line strengths
are difficult to detect in our data set.\r\n\r\nResults. The observed spectroscopic
binary fraction among stars brighter than mF814W = 19 (approximately 5.5 M⊙ on
the main sequence) is fSBobs = 13.2 ± 2.0%. Considering period and mass ratio
ranges from log(P) = 0.15−3.5 (about 1.4 to 3160 d), q = 0.1−1.0, and a representative
set of orbital parameter distributions, we find a bias-corrected close binary
fraction of fcl = 34−7+8%. This fraction seems to decline for the fainter stars,
which indicates either that the close binary fraction drops in the B-type domain,
or that the period distribution becomes more heavily weighted toward longer orbital
periods. We further find that both fractions vary strongly in different regions
of the color-magnitude diagram, which corresponds to different evolutionary stages.
This probably reveals the imprint of the binary history of different groups of
stars. In particular, we find that the observed spectroscopic binary fraction
of Be stars (fSBobs = 2 ± 2%) is significantly lower than that of B-type stars
(fSBobs = 9 ± 2%).\r\n\r\nConclusions. We provide the first homogeneous radial
velocity study of a large sample of B-type stars at a low metallicity ([Fe/H]
≲ −1.0). The overall bias-corrected close binary fraction (log(P) < 3.5 d) of
the B-star population in NGC 330 is lower than the fraction reported for younger
Galactic and Large Magellanic Cloud clusters in previous works. More data are
needed, however, to establish whether the observed differences are caused by an
age or a metallicity effect."

text: Most massive stars experience binary interactions in their lifetimes that
can alter both the surface and core structure of the stripped star with significant
effects on their ultimate fate as core-collapse supernovae. However, core-collapse
supernovae simulations to date have focused almost exclusively on the evolution
of single stars. We present a systematic simulation study of single and binary-stripped
stars with the same initial mass as candidates for core-collapse supernovae (11–21
M⊙). Generally, we find that binary-stripped stars core tend to have a smaller
compactness parameter, with a more prominent, deeper silicon/oxygen interface,
and explode preferentially to the corresponding single stars of the same initial
mass. Such a dichotomy of behavior between these two modes of evolution would
have important implications for supernovae statistics, including the final neutron
star masses, explosion energies, and nucleosynthetic yields. Binary-stripped remnants
are also well poised to populate the possible mass gap between the heaviest neutron
stars and the lightest black holes. Our work presents an improvement along two
fronts, as we self-consistently account for the pre-collapse stellar evolution
and the subsequent explosion outcome. Even so, our results emphasize the need
for more detailed stellar evolutionary models to capture the sensitive nature
of explosion outcome.

text: The B emission-line stars are rapid rotators that were probably spun up by
mass and angular momentum accretion through mass transfer in an interacting binary.
Mass transfer will strip the donor star of its envelope to create a small and
hot subdwarf remnant. Here we report on Hubble Space Telescope/STIS far-ultraviolet
spectroscopy of a sample of Be stars that reveals the presence of the hot sdO
companion through the calculation of cross-correlation functions of the observed
and model spectra. We clearly detect the spectral signature of the sdO star in
10 of the 13 stars in the sample, and the spectral signals indicate that the sdO
stars are hot, relatively faint, and slowly rotating as predicted by models. A
comparison of their temperatures and radii with evolutionary tracks indicates
that the sdO stars occupy the relatively long-lived, He-core burning stage. Only
1 of the 10 detections was a known binary prior to this investigation, which emphasizes
the difficulty of finding such Be+sdO binaries through optical spectroscopy. However,
these results and others indicate that many Be stars probably host hot subdwarf
companions.

text: Shape resonances play a central role in many areas of science, but the real-time
measurement of the associated many-body dynamics remains challenging. Here, we
present measurements of recoil frame angle-resolved photoionization delays in
the vicinity of shape resonances of CF4. This technique provides insights into
the spatiotemporal photoionization dynamics of molecular shape resonances. We
find delays of up to ∼600 as in the ionization out of the highest occupied molecular
orbital (HOMO) with a strong dependence on the emission direction and a pronounced
asymmetry along the dissociation axis. Comparison with quantum-scattering calculations
traces the asymmetries to the interference of a small subset of partial waves
at low kinetic energies and, additionally, to the interference of two overlapping
shape resonances in the HOMO-1 channel. Our experimental and theoretical results
establish a broadly applicable approach to space- and time-resolved photoionization
dynamics in the molecular frame.

text: We report the observation of an anomalous nonlinear optical response of the
prototypical three-dimensional topological insulator bismuth selenide through
the process of high-order harmonic generation. We find that the generation efficiency
increases as the laser polarization is changed from linear to elliptical, and
it becomes maximum for circular polarization. With the aid of a microscopic theory
and a detailed analysis of the measured spectra, we reveal that such anomalous
enhancement encodes the characteristic topology of the band structure that originates
from the interplay of strong spin–orbit coupling and time-reversal symmetry protection.
The implications are in ultrafast probing of topological phase transitions, light-field
driven dissipationless electronics, and quantum computation.

text: We investigate theoretically the strong-field regime of light-matter interactions
in the topological-insulator class of quantum materials. In particular, we focus
on the process of nonperturbative high-order harmonic generation from the paradigmatic
three-dimensional topological insulator bismuth selenide (Bi2Se3) subjected to
intense midinfrared laser fields. We analyze the contributions from the spin-orbit-coupled
bulk states and the topological surface bands separately and reveal a major difference
in how their harmonic yields depend on the ellipticity of the laser field. Bulk
harmonics show a monotonic decrease in their yield as the ellipticity increases,
in a manner reminiscent of high harmonic generation in gaseous media. However,
the surface contribution exhibits a highly nontrivial dependence, culminating
with a maximum for circularly polarized fields. We attribute the observed anomalous
behavior to (i) the enhanced amplitude and the circular pattern of the interband
dipole and the Berry connections in the vicinity of the Dirac point and (ii) the
influence of the higher-order, hexagonal warping terms in the Hamiltonian, which
are responsible for the hexagonal deformation of the energy surface at higher
momenta. The latter are associated directly with spin-orbit-coupling parameters.
Our results thus establish the sensitivity of strong-field-driven high harmonic
emission to the topology of the band structure as well as to the manifestations
of spin-orbit interaction.

text: UVEX is a proposed medium class Explorer mission designed to provide crucial
missing capabilities that will address objectives central to a broad range of
modern astrophysics. The UVEX design has two co-aligned wide-field imagers operating
in the FUV and NUV and a powerful broadband medium resolution spectrometer. In
its two-year baseline mission, UVEX will perform a multi-cadence synoptic all-sky
survey 50/100 times deeper than GALEX in the NUV/FUV, cadenced surveys of the
Large and Small Magellanic Clouds, rapid target of opportunity followup, as well
as spectroscopic followup of samples of stars and galaxies. The science program
is built around three pillars. First, UVEX will explore the low-mass, low-metallicity
galaxy frontier through imaging and spectroscopic surveys that will probe key
aspects of the evolution of galaxies by understanding how star formation and stellar
evolution at low metallicities affect the growth and evolution of low-metallicity,
low-mass galaxies in the local universe. Such galaxies contain half the mass in
the local universe, and are analogs for the first galaxies, but observed at distances
that make them accessible to detailed study. Second, UVEX will explore the dynamic
universe through time-domain surveys and prompt spectroscopic followup capability
will probe the environments, energetics, and emission processes in the early aftermaths
of gravitational wave-discovered compact object mergers, discover hot, fast UV
transients, and diagnose the early stages of stellar explosions. Finally, UVEX
will become a key community resource by leaving a large all-sky legacy data set,
enabling a wide range of scientific studies and filling a gap in the new generation
of wide-field, sensitive optical and infrared surveys provided by the Rubin, Euclid,
and Roman observatories. This paper discusses the scientific potential of UVEX,
and the broad scientific program.

text: 'The two fields of machine learning and graphical causality arose and are
developed separately. However, there is, now, cross-pollination and increasing
interest in both fields to benefit from the advances of the other. In this article,
we review fundamental concepts of causal inference and relate them to crucial
open problems of machine learning, including transfer and generalization, thereby
assaying how causality can contribute to modern machine learning research. This
also applies in the opposite direction: we note that most work in causality starts
from the premise that the causal variables are given. A central problem for AI
and causality is, thus, causal representation learning, that is, the discovery
of high-level causal variables from low-level observations. Finally, we delineate
some implications of causality for machine learning and propose key research areas
at the intersection of both communities.'

text: "Intensive care units (ICU) are increasingly looking towards machine learning
for methods to provide online monitoring of critically ill patients. In machine
learning, online monitoring is often formulated as a supervised learning problem.
Recently, contrastive learning approaches have demonstrated promising improvements
over competitive supervised benchmarks. These methods rely on well-understood
data augmentation techniques developed for image data which do not apply to online
monitoring. In this work, we overcome this limitation by\r\nsupplementing time-series
data augmentation techniques with a novel contrastive\r\nlearning objective which
we call neighborhood contrastive learning (NCL). Our objective explicitly groups
together contiguous time segments from each patient while maintaining state-specific
information. Our experiments demonstrate a marked improvement over existing work
applying contrastive methods to medical time-series."

text: "The focus of disentanglement approaches has been on identifying independent
factors of variation in data. However, the causal variables underlying real-world
observations are often not statistically independent. In this work, we bridge
the gap to real-world scenarios by analyzing the behavior of the most prominent
disentanglement approaches on correlated data in a large-scale empirical study
(including 4260 models). We show and quantify that systematically induced correlations
in the dataset are being learned and reflected in the latent representations,
which has implications for downstream applications of disentanglement such as
fairness. We also demonstrate how to resolve these latent correlations, either
using weak supervision during\r\ntraining or by post-hoc correcting a pre-trained
model with a small number of labels."

text: Learning meaningful representations that disentangle the underlying structure
of the data generating process is considered to be of key importance in machine
learning. While disentangled representations were found to be useful for diverse
tasks such as abstract reasoning and fair classification, their scalability and
real-world impact remain questionable. We introduce a new high-resolution dataset
with 1M simulated images and over 1,800 annotated real-world images of the same
setup. In contrast to previous work, this new dataset exhibits correlations, a
complex underlying structure, and allows to evaluate transfer to unseen simulated
and real-world settings where the encoder i) remains in distribution or ii) is
out of distribution. We propose new architectures in order to scale disentangled
representation learning to realistic high-resolution settings and conduct a large-scale
empirical study of disentangled representations on this dataset. We observe that
disentanglement is a good predictor for out-of-distribution (OOD) task performance.
