text: We consider the quantum many-body evolution of a homogeneous Fermi gas in
three dimensions in the coupled semiclassical and mean-field scaling regime. We
study a class of initial data describing collective particle–hole pair excitations
on the Fermi ball. Using a rigorous version of approximate bosonization, we prove
that the many-body evolution can be approximated in Fock space norm by a quasi-free
bosonic evolution of the collective particle–hole excitations.

text: We derive optimal-order homogenization rates for random nonlinear elliptic
PDEs with monotone nonlinearity in the uniformly elliptic case. More precisely,
for a random monotone operator on \mathbb {R}^d with stationary law (that is spatially
homogeneous statistics) and fast decay of correlations on scales larger than the
microscale \varepsilon >0, we establish homogenization error estimates of the
order \varepsilon in case d\geqq 3, and of the order \varepsilon |\log \varepsilon
|^{1/2} in case d=2. Previous results in nonlinear stochastic homogenization have
been limited to a small algebraic rate of convergence \varepsilon ^\delta . We
also establish error estimates for the approximation of the homogenized operator
by the method of representative volumes of the order (L/\varepsilon )^{-d/2} for
a representative volume of size L. Our results also hold in the case of systems
for which a (small-scale) C^{1,\alpha } regularity theory is available.

text: We show that Yao’s garbling scheme is adaptively indistinguishable for the
class of Boolean circuits of size S and treewidth w with only a SO(w) loss
in security. For instance, circuits with constant treewidth are as a result adaptively
indistinguishable with only a polynomial loss. This (partially) complements a
negative result of Applebaum et al. (Crypto 2013), which showed (assuming one-way
functions) that Yao’s garbling scheme cannot be adaptively simulatable. As main
technical contributions, we introduce a new pebble game that abstracts out our
security reduction and then present a pebbling strategy for this game where the
number of pebbles used is roughly O(δwlog(S)) , δ being the fan-out of the
circuit. The design of the strategy relies on separators, a graph-theoretic notion
with connections to circuit complexity. with only a SO(w) loss in security.

text: Classical models with complex energy landscapes represent a perspective avenue
for the near-term application of quantum simulators. Until now, many theoretical
works studied the performance of quantum algorithms for models with a unique ground
state. However, when the classical problem is in a so-called clustering phase,
the ground state manifold is highly degenerate. As an example, we consider a 3-XORSAT
model defined on simple hypergraphs. The degeneracy of classical ground state
manifold translates into the emergence of an extensive number of Z2 symmetries,
which remain intact even in the presence of a quantum transverse magnetic field.
We establish a general duality approach that restricts the quantum problem to
a given sector of conserved Z2 charges and use it to study how the outcome of
the quantum adiabatic algorithm depends on the hypergraph geometry. We show that
the tree hypergraph which corresponds to a classically solvable instance of the
3-XORSAT problem features a constant gap, whereas the closed hypergraph encounters
a second-order phase transition with a gap vanishing as a power-law in the problem
size. The duality developed in this work provides a practical tool for studies
of quantum models with classically degenerate energy manifold and reveals potential
connections between glasses and gauge theories.

text: 'We present DAG-Rider, the first asynchronous Byzantine Atomic Broadcast protocol
that achieves optimal resilience, optimal amortized communication complexity,
and optimal time complexity. DAG-Rider is post-quantum safe and ensures that all
values proposed by correct processes eventually get delivered. We construct DAG-Rider
in two layers: In the first layer, processes reliably broadcast their proposals
and build a structured Directed Acyclic Graph (DAG) of the communication among
them. In the second layer, processes locally observe their DAGs and totally order
all proposals with no extra communication.'

text: Genetic adaptation and phenotypic plasticity facilitate the migration into
new habitats and enable organisms to cope with a rapidly changing environment.
In contrast to genetic adaptation that spans multiple generations as an evolutionary
process, phenotypic plasticity allows acclimation within the life-time of an organism.
Genetic adaptation and phenotypic plasticity are usually studied in isolation,
however, only by including their interactive impact, we can understand acclimation
and adaptation in nature. We aimed to explore the contribution of adaptation and
plasticity in coping with an abiotic (salinity) and a biotic (Vibrio bacteria)
stressor using six different populations of the broad-nosed pipefish Syngnathus
typhle that originated from either high [14–17 Practical Salinity Unit (PSU)]
or low (7–11 PSU) saline environments along the German coastline of the Baltic
Sea. We exposed wild caught animals, to either high (15 PSU) or low (7 PSU) salinity,
representing native and novel salinity conditions and allowed animals to mate.
After male pregnancy, offspring was split and each half was exposed to one of
the two salinities and infected with Vibrio alginolyticus bacteria that were evolved
at either of the two salinities in a fully reciprocal design. We investigated
life-history traits of fathers and expression of 47 target genes in mothers and
offspring. Pregnant males originating from high salinity exposed to low salinity
were highly susceptible to opportunistic fungi infections resulting in decreased
offspring size and number. In contrast, no signs of fungal infection were identified
in fathers originating from low saline conditions suggesting that genetic adaptation
has the potential to overcome the challenges encountered at low salinity. Offspring
from parents with low saline origin survived better at low salinity suggesting
genetic adaptation to low salinity. In addition, gene expression analyses of juveniles
indicated patterns of local adaptation, trans-generational plasticity and developmental
plasticity. In conclusion, our study suggests that pipefish are locally adapted
to the low salinity in their environment, however, they are retaining phenotypic
plasticity, which allows them to also cope with ancestral salinity levels and
prevailing pathogens.

text: A facile approach for developing an interfacial solar evaporator by heat localization
of solar-thermal energy conversion at water-air liquid composed by in-situ polymerization
of Fe2O3 nanoparticles (Fe2O3@PPy) deposited over a facial sponge is proposed.
The demonstrated system consists of a floating solar receiver having a vertically
cross-linked microchannel for wicking up saline water. The in situ polymerized
Fe2O3@PPy interfacial layer promotes diffuse reflection and its rough black surface
allows Omni-directional solar absorption (94%) and facilitates efficient thermal
localization at the water/air interface and offers a defect-rich surface to promote
heat localization (41.9 °C) and excellent thermal management due to cellulosic
content. The self-floating composite foam reveals continuous vapors generation
at a rate of 1.52 kg m−2 h−1 under one 1 kW m−2 and profound evaporating efficiency
(95%) without heat losses that dissipates in its surroundings. Indeed, long-term
evaporation experiments reveal the negligible disparity in continuous evaporation
rate (33.84 kg m−2/8.3 h) receiving two sun solar intensity, and ensures the stability
of the device under intense seawater conditions synchronized with excellent salt
rejection potential. More importantly, Raman spectroscopy investigation validates
the orange dye rejection via Fe2O3@PPy solar evaporator. The combined advantages
of high efficiency, self-floating capability, multimedia rejection, low cost,
and this configuration are promising for producing large-scale solar steam generating
systems appropriate for commercial clean water yield due to their scalable fabrication.

text: 'For animals to survive until reproduction, it is crucial that juveniles successfully
detect potential predators and respond with appropriate behavior. The recognition
of cues originating from predators can be innate or learned. Cues of various modalities
might be used alone or in multi-modal combinations to detect and distinguish predators
but studies investigating multi-modal integration in predator avoidance are scarce.
Here, we used wild, naive tadpoles of the Neotropical poison frog Allobates femoralis
( Boulenger, 1884) to test their reaction to cues with two modalities from two
different sympatrically occurring potential predators: heterospecific predatory
Dendrobates tinctorius tadpoles and dragonfly larvae. We presented A. femoralis
tadpoles with olfactory or visual cues, or a combination of the two, and compared
their reaction to a water control in a between-individual design. In our trials,
A. femoralis tadpoles reacted to multi-modal stimuli (a combination of visual
and chemical information) originating from dragonfly larvae with avoidance but
showed no reaction to uni-modal cues or cues from heterospecific tadpoles. In
addition, visual cues from conspecifics increased swimming activity while cues
from predators had no effect on tadpole activity. Our results show that A. femoralis
tadpoles can innately recognize some predators and probably need both visual and
chemical information to effectively avoid them. This is the first study looking
at anti-predator behavior in poison frog tadpoles. We discuss how parental care
might influence the expression of predator avoidance responses in tadpoles.'

text: The choice of the boundary conditions in mechanical problems has to reflect
the interaction of the considered material with the surface. Still the assumption
of the no-slip condition is preferred in order to avoid boundary terms in the
analysis and slipping effects are usually overlooked. Besides the “static slip
models”, there are phenomena that are not accurately described by them, e.g. at
the moment when the slip changes rapidly, the wall shear stress and the slip can
exhibit a sudden overshoot and subsequent relaxation. When these effects become
significant, the so-called dynamic slip phenomenon occurs. We develop a mathematical
analysis of Navier–Stokes-like problems with a dynamic slip boundary condition,
which requires a proper generalization of the Gelfand triplet and the corresponding
function space setting.

text: 'The understanding of material appearance perception is a complex problem
due to interactions between material reflectance, surface geometry, and illumination.
Recently, Serrano et al. collected the largest dataset to date with subjective
ratings of material appearance attributes, including glossiness, metallicness,
sharpness and contrast of reflections. In this work, we make use of their dataset
to investigate for the first time the impact of the interactions between illumination,
geometry, and eight different material categories in perceived appearance attributes.
After an initial analysis, we select for further analysis the four material categories
that cover the largest range for all perceptual attributes: fabric, plastic, ceramic,
and metal. Using a cumulative link mixed model (CLMM) for robust regression, we
discover interactions between these material categories and four representative
illuminations and object geometries. We believe that our findings contribute to
expanding the knowledge on material appearance perception and can be useful for
many applications, such as scene design, where any particular material in a given
shape can be aligned with dominant classes of illumination, so that a desired
strength of appearance attributes can be achieved.'

text: How tissues acquire complex shapes is a fundamental question in biology and
regenerative medicine. Zebrafish semicircular canals form from invaginations in
the otic epithelium (buds) that extend and fuse to form the hubs of each canal.
We find that conventional actomyosin-driven behaviors are not required. Instead,
local secretion of hyaluronan, made by the enzymes uridine 5′-diphosphate dehydrogenase
(ugdh) and hyaluronan synthase 3 (has3), drives canal morphogenesis. Charged hyaluronate
polymers osmotically swell with water and generate isotropic extracellular pressure
to deform the overlying epithelium into buds. The mechanical anisotropy needed
to shape buds into tubes is conferred by a polarized distribution of actomyosin
and E-cadherin-rich membrane tethers, which we term cytocinches. Most work on
tissue morphogenesis ascribes actomyosin contractility as the driving force, while
the extracellular matrix shapes tissues through differential stiffness. Our work
inverts this expectation. Hyaluronate pressure shaped by anisotropic tissue stiffness
may be a widespread mechanism for powering morphological change in organogenesis
and tissue engineering.

text: 'In two-player games on graphs, the players move a token through a graph to
produce an infinite path, which determines the winner of the game. Such games
are central in formal methods since they model the interaction between a non-terminating
system and its environment. In bidding games the players bid for the right to
move the token: in each round, the players simultaneously submit bids, and the
higher bidder moves the token and pays the other player. Bidding games are known
to have a clean and elegant mathematical structure that relies on the ability
of the players to submit arbitrarily small bids. Many applications, however, require
a fixed granularity for the bids, which can represent, for example, the monetary
value expressed in cents. We study, for the first time, the combination of discrete-bidding
and infinite-duration games. Our most important result proves that these games
form a large determined subclass of concurrent games, where determinacy is the
strong property that there always exists exactly one player who can guarantee
winning the game. In particular, we show that, in contrast to non-discrete bidding
games, the mechanism with which tied bids are resolved plays an important role
in discrete-bidding games. We study several natural tie-breaking mechanisms and
show that, while some do not admit determinacy, most natural mechanisms imply
determinacy for every pair of initial budgets.'

text: "We study Multi-party computation (MPC) in the setting of subversion, where
the adversary tampers with the machines of honest parties. Our goal is to construct
actively secure MPC protocols where parties are corrupted adaptively by an adversary
(as in the standard adaptive security setting), and in addition, honest parties’
machines are compromised.\r\nThe idea of reverse firewalls (RF) was introduced
at EUROCRYPT’15 by Mironov and Stephens-Davidowitz as an approach to protecting
protocols against corruption of honest parties’ devices. Intuitively, an RF for
a party P is an external entity that sits between P and the outside world
and whose scope is to sanitize P ’s incoming and outgoing messages in the face
of subversion of their computer. Mironov and Stephens-Davidowitz constructed a
protocol for passively-secure two-party computation. At CRYPTO’20, Chakraborty,
Dziembowski and Nielsen constructed a protocol for secure computation with firewalls
that improved on this result, both by extending it to multi-party computation
protocol, and considering active security in the presence of static corruptions.
In this paper, we initiate the study of RF for MPC in the adaptive setting. We
put forward a definition for adaptively secure MPC in the reverse firewall setting,
explore relationships among the security notions, and then construct reverse firewalls
for MPC in this stronger setting of adaptive security. We also resolve the open
question of Chakraborty, Dziembowski and Nielsen by removing the need for a trusted
setup in constructing RF for MPC. Towards this end, we construct reverse firewalls
for adaptively secure augmented coin tossing and adaptively secure zero-knowledge
protocols and obtain a constant round adaptively secure MPC protocol in the reverse
firewall setting without setup. Along the way, we propose a new multi-party adaptively
secure coin tossing protocol in the plain model, that is of independent interest."

text: Cell division orientation is thought to result from a competition between
cell geometry and polarity domains controlling the position of the mitotic spindle
during mitosis. Depending on the level of cell shape anisotropy or the strength
of the polarity domain, one dominates the other and determines the orientation
of the spindle. Whether and how such competition is also at work to determine
unequal cell division (UCD), producing daughter cells of different size, remains
unclear. Here, we show that cell geometry and polarity domains cooperate, rather
than compete, in positioning the cleavage plane during UCDs in early ascidian
embryos. We found that the UCDs and their orientation at the ascidian third cleavage
rely on the spindle tilting in an anisotropic cell shape, and cortical polarity
domains exerting different effects on spindle astral microtubules. By systematically
varying mitotic cell shape, we could modulate the effect of attractive and repulsive
polarity domains and consequently generate predicted daughter cell size asymmetries
and position. We therefore propose that the spindle position during UCD is set
by the combined activities of cell geometry and polarity domains, where cell geometry
modulates the effect of cortical polarity domain(s).

text: The evidence linking innate immunity mechanisms and neurodegenerative diseases
is growing, but the specific mechanisms are incompletely understood. Experimental
data suggest that microglial TLR4 mediates the uptake and clearance of α-synuclein
also termed synucleinophagy. The accumulation of misfolded α-synuclein throughout
the brain is central to Parkinson's disease (PD). The distribution and progression
of the pathology is often attributed to the propagation of α-synuclein. Here,
we apply a classical α-synuclein propagation model of prodromal PD in wild type
and TLR4 deficient mice to study the role of TLR4 in the progression of the disease.
Our data suggest that TLR4 deficiency facilitates the α-synuclein seed spreading
associated with reduced lysosomal activity of microglia. Three months after seed
inoculation, more pronounced proteinase K-resistant α-synuclein inclusion pathology
is observed in mice with TLR4 deficiency. The facilitated propagation of α-synuclein
is associated with early loss of dopamine transporter (DAT) signal in the striatum
and loss of dopaminergic neurons in substantia nigra pars compacta of TLR4 deficient
mice. These new results support TLR4 signaling as a putative target for disease
modification to slow the progression of PD and related disorders.

text: The surface states of 3D topological insulators in general have negligible
quantum oscillations (QOs) when the chemical potential is tuned to the Dirac points.
In contrast, we find that topological Kondo insulators (TKIs) can support surface
states with an arbitrarily large Fermi surface (FS) when the chemical potential
is pinned to the Dirac point. We illustrate that these FSs give rise to finite-frequency
QOs, which can become comparable to the extremal area of the unhybridized bulk
bands. We show that this occurs when the crystal symmetry is lowered from cubic
to tetragonal in a minimal two-orbital model. We label such surface modes as 'shadow
surface states'. Moreover, we show that the sufficient next-nearest neighbor out-of-plane
hybridization leading to shadow surface states can be self-consistently stabilized
for tetragonal TKIs. Consequently, shadow surface states provide an important
example of high-frequency QOs beyond the context of cubic TKIs.

text: We combine experimental and theoretical approaches to explore excited rotational
states of molecules embedded in helium nanodroplets using CS2 and I2 as examples.
Laser-induced nonadiabatic molecular alignment is employed to measure spectral
lines for rotational states extending beyond those initially populated at the
0.37 K droplet temperature. We construct a simple quantum-mechanical model, based
on a linear rotor coupled to a single-mode bosonic bath, to determine the rotational
energy structure in its entirety. The calculated and measured spectral lines are
in good agreement. We show that the effect of the surrounding superfluid on molecular
rotation can be rationalized by a single quantity, the angular momentum, transferred
from the molecule to the droplet.

text: Adversarial training is an effective method to train deep learning models
that are resilient to norm-bounded perturbations, with the cost of nominal performance
drop. While adversarial training appears to enhance the robustness and safety
of a deep model deployed in open-world decision-critical applications, counterintuitively,
it induces undesired behaviors in robot learning settings. In this paper, we show
theoretically and experimentally that neural controllers obtained via adversarial
training are subjected to three types of defects, namely transient, systematic,
and conditional errors. We first generalize adversarial training to a safety-domain
optimization scheme allowing for more generic specifications. We then prove that
such a learning process tends to cause certain error profiles. We support our
theoretical results by a thorough experimental safety analysis in a robot-learning
task. Our results suggest that adversarial training is not yet ready for robot
learning.

text: In this paper, we investigate the distribution of the maximum of partial sums
of families of m -periodic complex-valued functions satisfying certain conditions.
We obtain precise uniform estimates for the distribution function of this maximum
in a near-optimal range. Our results apply to partial sums of Kloosterman sums
and other families of ℓ -adic trace functions, and are as strong as those obtained
by Bober, Goldmakher, Granville and Koukoulopoulos for character sums. In particular,
we improve on the recent work of the third author for Birch sums. However, unlike
character sums, we are able to construct families of m -periodic complex-valued
functions which satisfy our conditions, but for which the Pólya–Vinogradov inequality
is sharp.

text: The cost-effective conversion of low-grade heat into electricity using thermoelectric
devices requires developing alternative materials and material processing technologies
able to reduce the currently high device manufacturing costs. In this direction,
thermoelectric materials that do not rely on rare or toxic elements such as tellurium
or lead need to be produced using high-throughput technologies not involving high
temperatures and long processes. Bi2Se3 is an obvious possible Te-free alternative
to Bi2Te3 for ambient temperature thermoelectric applications, but its performance
is still low for practical applications, and additional efforts toward finding
proper dopants are required. Here, we report a scalable method to produce Bi2Se3
nanosheets at low synthesis temperatures. We studied the influence of different
dopants on the thermoelectric properties of this material. Among the elements
tested, we demonstrated that Sn doping resulted in the best performance. Sn incorporation
resulted in a significant improvement to the Bi2Se3 Seebeck coefficient and a
reduction in the thermal conductivity in the direction of the hot-press axis,
resulting in an overall 60% improvement in the thermoelectric figure of merit
of Bi2Se3.

text: Hematopoietic-specific protein 1 (Hem1) is an essential subunit of the WAVE
regulatory complex (WRC) in immune cells. WRC is crucial for Arp2/3 complex activation
and the protrusion of branched actin filament networks. Moreover, Hem1 loss of
function in immune cells causes autoimmune diseases in humans. Here, we show that
genetic removal of Hem1 in macrophages diminishes frequency and efficacy of phagocytosis
as well as phagocytic cup formation in addition to defects in lamellipodial protrusion
and migration. Moreover, Hem1-null macrophages displayed strong defects in cell
adhesion despite unaltered podosome formation and concomitant extracellular matrix
degradation. Specifically, dynamics of both adhesion and de-adhesion as well as
concomitant phosphorylation of paxillin and focal adhesion kinase (FAK) were significantly
compromised. Accordingly, disruption of WRC function in non-hematopoietic cells
coincided with both defects in adhesion turnover and altered FAK and paxillin
phosphorylation. Consistently, platelets exhibited reduced adhesion and diminished
integrin αIIbβ3 activation upon WRC removal. Interestingly, adhesion phenotypes,
but not lamellipodia formation, were partially rescued by small molecule activation
of FAK. A full rescue of the phenotype, including lamellipodia formation, required
not only the presence of WRCs but also their binding to and activation by Rac.
Collectively, our results uncover that WRC impacts on integrin-dependent processes
in a FAK-dependent manner, controlling formation and dismantling of adhesions,
relevant for properly grabbing onto extracellular surfaces and particles during
cell edge expansion, like in migration or phagocytosis.

text: "We present a deterministic O(log log log n)-round low-space Massively Parallel
Computation (MPC) algorithm for the classical problem of (Δ+1)-coloring on n-vertex
graphs. In this model, every machine has sublinear local space of size n^φ for
any arbitrary constant φ \\in (0,1). Our algorithm works under the relaxed setting
where each machine is allowed to perform exponential local computations, while
respecting the n^φ space and bandwidth limitations.\r\n\r\nOur key technical contribution
is a novel derandomization of the ingenious (Δ+1)-coloring local algorithm by
Chang-Li-Pettie (STOC 2018, SIAM J. Comput. 2020). The Chang-Li-Pettie algorithm
runs in T_local =poly(loglog n) rounds, which sets the state-of-the-art randomized
round complexity for the problem in the local model. Our derandomization employs
a combination of tools, notably pseudorandom generators (PRG) and bounded-independence
hash functions.\r\n\r\nThe achieved round complexity of O(logloglog n) rounds
matches the bound of log(T_local ), which currently serves an upper bound barrier
for all known randomized algorithms for locally-checkable problems in this model.
Furthermore, no deterministic sublogarithmic low-space MPC algorithms for the
(Δ+1)-coloring problem have been known before."

text: "We study the properties of the maximal volume k-dimensional sections of the
n-dimensional cube [−1, 1]n. We obtain a first order necessary condition for a
k-dimensional subspace to be a local maximizer of the volume of such sections,
which we formulate in a geometric way. We estimate the length of the projection
of a vector of the standard basis of Rn onto a k-dimensional subspace that maximizes
the volume of the intersection. We \x1Cnd the optimal upper bound on the volume
of a planar section of the cube [−1, 1]n , n ≥ 2."

text: "In this paper, we study the power and limitations of component-stable algorithms
in the low-space model of Massively Parallel Computation (MPC). Recently Ghaffari,
Kuhn and Uitto (FOCS 2019) introduced the class of component-stable low-space
MPC algorithms, which are, informally, defined as algorithms for which the outputs
reported by the nodes in different connected components are required to be independent.
This very natural notion was introduced to capture most (if not all) of the known
efficient MPC algorithms to date, and it was the first general class of MPC algorithms
for which one can show non-trivial conditional lower bounds. In this paper we
enhance the framework of component-stable algorithms and investigate its effect
on the complexity of randomized and deterministic low-space MPC. Our key contributions
include: 1) We revise and formalize the lifting approach of Ghaffari, Kuhn and
Uitto. This requires a very delicate amendment of the notion of component stability,
which allows us to fill in gaps in the earlier arguments. 2) We also extend the
framework to obtain conditional lower bounds for deterministic algorithms and
fine-grained lower bounds that depend on the maximum degree Δ. 3) We demonstrate
a collection of natural graph problems for which non-component-stable algorithms
break the conditional lower bound obtained for component-stable algorithms. This
implies that, for both deterministic and randomized algorithms, component-stable
algorithms are conditionally weaker than the non-component-stable ones.\r\n\r\nAltogether
our results imply that component-stability might limit the computational power
of the low-space MPC model, paving the way for improved upper bounds that escape
the conditional lower bound setting of Ghaffari, Kuhn, and Uitto."

text: We derive rigorously the leading order of the correlation energy of a Fermi
gas in a scaling regime of high density and weak interaction. The result verifies
the prediction of the random-phase approximation. Our proof refines the method
of collective bosonization in three dimensions. We approximately diagonalize an
effective Hamiltonian describing approximately bosonic collective excitations
around the Hartree–Fock state, while showing that gapless and non-collective excitations
have only a negligible effect on the ground state energy.

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: 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.

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: 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: 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: 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: 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: 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: 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: We study systems of nonlinear partial differential equations of parabolic
type, in which the elliptic operator is replaced by the first-order divergence
operator acting on a flux function, which is related to the spatial gradient of
the unknown through an additional implicit equation. This setting, broad enough
in terms of applications, significantly expands the paradigm of nonlinear parabolic
problems. Formulating four conditions concerning the form of the implicit equation,
we first show that these conditions describe a maximal monotone p-coercive graph.
We then establish the global-in-time and large-data existence of a (weak) solution
and its uniqueness. To this end, we adopt and significantly generalize Minty’s
method of monotone mappings. A unified theory, containing several novel tools,
is developed in a way to be tractable from the point of view of numerical approximations.

text: The popularity of permissioned blockchain systems demands BFT SMR protocols
that are efficient under good network conditions (synchrony) and robust under
bad network conditions (asynchrony). The state-of-the-art partially synchronous
BFT SMR protocols provide optimal linear communication cost per decision under
synchrony and good leaders, but lose liveness under asynchrony. On the other hand,
the state-of-the-art asynchronous BFT SMR protocols are live even under asynchrony,
but always pay quadratic cost even under synchrony. In this paper, we propose
a BFT SMR protocol that achieves the best of both worlds -- optimal linear cost
per decision under good networks and leaders, optimal quadratic cost per decision
under bad networks, and remains always live.

text: The analogy between an equilibrium partition function and the return probability
in many-body unitary dynamics has led to the concept of dynamical quantum phase
transition (DQPT). DQPTs are defined by nonanalyticities in the return amplitude
and are present in many models. In some cases, DQPTs can be related to equilibrium
concepts, such as order parameters, yet their universal description is an open
question. In this Letter, we provide first steps toward a classification of DQPTs
by using a matrix product state description of unitary dynamics in the thermodynamic
limit. This allows us to distinguish the two limiting cases of “precession” and
“entanglement” DQPTs, which are illustrated using an analytical description in
the quantum Ising model. While precession DQPTs are characterized by a large entanglement
gap and are semiclassical in their nature, entanglement DQPTs occur near avoided
crossings in the entanglement spectrum and can be distinguished by a complex pattern
of nonlocal correlations. We demonstrate the existence of precession and entanglement
DQPTs beyond Ising models, discuss observables that can distinguish them, and
relate their interplay to complex DQPT phenomenology.

text: The quality control system for messenger RNA (mRNA) is fundamental for cellular
activities in eukaryotes. To elucidate the molecular mechanism of 3'-Phosphoinositide-Dependent
Protein Kinase1 (PDK1), a master regulator that is essential throughout eukaryotic
growth and development, we employed a forward genetic approach to screen for suppressors
of the loss-of-function T-DNA insertion double mutant pdk1.1 pdk1.2 in Arabidopsis
thaliana. Notably, the severe growth attenuation of pdk1.1 pdk1.2 was rescued
by sop21 (suppressor of pdk1.1 pdk1.2), which harbours a loss-of-function mutation
in PELOTA1 (PEL1). PEL1 is a homologue of mammalian PELOTA and yeast (Saccharomyces
cerevisiae) DOM34p, which each form a heterodimeric complex with the GTPase HBS1
(HSP70 SUBFAMILY B SUPPRESSOR1, also called SUPERKILLER PROTEIN7, SKI7), a protein
that is responsible for ribosomal rescue and thereby assures the quality and fidelity
of mRNA molecules during translation. Genetic analysis further revealed that a
dysfunctional PEL1-HBS1 complex failed to degrade the T-DNA-disrupted PDK1 transcripts,
which were truncated but functional, and thus rescued the growth and developmental
defects of pdk1.1 pdk1.2. Our studies demonstrated the functionality of a homologous
PELOTA-HBS1 complex and identified its essential regulatory role in plants, providing
insights into the mechanism of mRNA quality control.

text: A tight frame is the orthogonal projection of some orthonormal basis of Rn
onto Rk. We show that a set of vectors is a tight frame if and only if the set
of all cross products of these vectors is a tight frame. We reformulate a range
of problems on the volume of projections (or sections) of regular polytopes in
terms of tight frames and write a first-order necessary condition for local extrema
of these problems. As applications, we prove new results for the problem of maximization
of the volume of zonotopes.

text: Polar subcellular localization of the PIN exporters of the phytohormone auxin
is a key determinant of directional, intercellular auxin transport and thus a
central topic of both plant cell and developmental biology. Arabidopsis mutants
lacking PID, a kinase that phosphorylates PINs, or the MAB4/MEL proteins of unknown
molecular function display PIN polarity defects and phenocopy pin mutants, but
mechanistic insights into how these factors convey PIN polarity are missing. Here,
by combining protein biochemistry with quantitative live-cell imaging, we demonstrate
that PINs, MAB4/MELs, and AGC kinases interact in the same complex at the plasma
membrane. MAB4/MELs are recruited to the plasma membrane by the PINs and in concert
with the AGC kinases maintain PIN polarity through limiting lateral diffusion-based
escape of PINs from the polar domain. The PIN-MAB4/MEL-PID protein complex has
self-reinforcing properties thanks to positive feedback between AGC kinase-mediated
PIN phosphorylation and MAB4/MEL recruitment. We thus uncover the molecular mechanism
by which AGC kinases and MAB4/MEL proteins regulate PIN localization and plant
development.

text: Plants are able to orient their growth according to gravity, which ultimately
controls both shoot and root architecture.1 Gravitropism is a dynamic process
whereby gravistimulation induces the asymmetric distribution of the plant hormone
auxin, leading to asymmetric growth, organ bending, and subsequent reset of auxin
distribution back to the original pre-gravistimulation situation.1, 2, 3 Differential
auxin accumulation during the gravitropic response depends on the activity of
polarly localized PIN-FORMED (PIN) auxin-efflux carriers.1, 2, 3, 4 In particular,
the timing of this dynamic response is regulated by PIN2,5,6 but the underlying
molecular mechanisms are poorly understood. Here, we show that MEMBRANE ASSOCIATED
KINASE REGULATOR2 (MAKR2) controls the pace of the root gravitropic response.
We found that MAKR2 is required for the PIN2 asymmetry during gravitropism by
acting as a negative regulator of the cell-surface signaling mediated by the receptor-like
kinase TRANSMEMBRANE KINASE1 (TMK1).2,7, 8, 9, 10 Furthermore, we show that
the MAKR2 inhibitory effect on TMK1 signaling is antagonized by auxin itself,
which triggers rapid MAKR2 membrane dissociation in a TMK1-dependent manner. Our
findings suggest that the timing of the root gravitropic response is orchestrated
by the reversible inhibition of the TMK1 signaling pathway at the cell surface.

text: Electrodepositing insulating lithium peroxide (Li2O2) is the key process during
discharge of aprotic Li–O2 batteries and determines rate, capacity, and reversibility.
Current understanding states that the partition between surface adsorbed and dissolved
lithium superoxide governs whether Li2O2 grows as a conformal surface film or
larger particles, leading to low or high capacities, respectively. However, better
understanding governing factors for Li2O2 packing density and capacity requires
structural sensitive in situ metrologies. Here, we establish in situ small- and
wide-angle X-ray scattering (SAXS/WAXS) as a suitable method to record the Li2O2
phase evolution with atomic to submicrometer resolution during cycling a custom-built
in situ Li–O2 cell. Combined with sophisticated data analysis, SAXS allows retrieving
rich quantitative structural information from complex multiphase systems. Surprisingly,
we find that features are absent that would point at a Li2O2 surface film formed
via two consecutive electron transfers, even in poorly solvating electrolytes
thought to be prototypical for surface growth. All scattering data can be modeled
by stacks of thin Li2O2 platelets potentially forming large toroidal particles.
Li2O2 solution growth is further justified by rotating ring-disk electrode measurements
and electron microscopy. Higher discharge overpotentials lead to smaller Li2O2
particles, but there is no transition to an electronically passivating, conformal
Li2O2 coating. Hence, mass transport of reactive species rather than electronic
transport through a Li2O2 film limits the discharge capacity. Provided that species
mobilities and carbon surface areas are high, this allows for high discharge capacities
even in weakly solvating electrolytes. The currently accepted Li–O2 reaction mechanism
ought to be reconsidered.

text: Dendritic cells (DCs) are crucial for the priming of naive T cells and the
initiation of adaptive immunity. Priming is initiated at a heterologous cell–cell
contact, the immunological synapse (IS). While it is established that F-actin
dynamics regulates signaling at the T cell side of the contact, little is known
about the cytoskeletal contribution on the DC side. Here, we show that the DC
actin cytoskeleton is decisive for the formation of a multifocal synaptic structure,
which correlates with T cell priming efficiency. DC actin at the IS appears in
transient foci that are dynamized by the WAVE regulatory complex (WRC). The absence
of the WRC in DCs leads to stabilized contacts with T cells, caused by an increase
in ICAM1-integrin–mediated cell–cell adhesion. This results in lower numbers of
activated and proliferating T cells, demonstrating an important role for DC actin
in the regulation of immune synapse functionality.

text: The sensory and cognitive abilities of the mammalian neocortex are underpinned
by intricate columnar and laminar circuits formed from an array of diverse neuronal
populations. One approach to determining how interactions between these circuit
components give rise to complex behavior is to investigate the rules by which
cortical circuits are formed and acquire functionality during development. This
review summarizes recent research on the development of the neocortex, from genetic
determination in neural stem cells through to the dynamic role that specific neuronal
populations play in the earliest circuits of neocortex, and how they contribute
to emergent function and cognition. While many of these endeavors take advantage
of model systems, consideration will also be given to advances in our understanding
of activity in nascent human circuits. Such cross-species perspective is imperative
when investigating the mechanisms underlying the dysfunction of early neocortical
circuits in neurodevelopmental disorders, so that one can identify targets amenable
to therapeutic intervention.

text: "We study the problem of recovering an unknown signal \U0001D465\U0001D465
given measurements obtained from a generalized linear model with a Gaussian sensing
matrix. Two popular solutions are based on a linear estimator \U0001D465\U0001D465^L
and a spectral estimator \U0001D465\U0001D465^s. The former is a data-dependent
linear combination of the columns of the measurement matrix, and its analysis
is quite simple. The latter is the principal eigenvector of a data-dependent matrix,
and a recent line of work has studied its performance. In this paper, we show
how to optimally combine \U0001D465\U0001D465^L and \U0001D465\U0001D465^s. At
the heart of our analysis is the exact characterization of the empirical joint
distribution of (\U0001D465\U0001D465,\U0001D465\U0001D465^L,\U0001D465\U0001D465^s)
in the high-dimensional limit. This allows us to compute the Bayes-optimal combination
of \U0001D465\U0001D465^L and \U0001D465\U0001D465^s, given the limiting distribution
of the signal \U0001D465\U0001D465. When the distribution of the signal is Gaussian,
then the Bayes-optimal combination has the form \U0001D703\U0001D465\U0001D465^L+\U0001D465\U0001D465^s
and we derive the optimal combination coefficient. In order to establish the limiting
distribution of (\U0001D465\U0001D465,\U0001D465\U0001D465^L,\U0001D465\U0001D465^s),
we design and analyze an approximate message passing algorithm whose iterates
give \U0001D465\U0001D465^L and approach \U0001D465\U0001D465^s. Numerical simulations
demonstrate the improvement of the proposed combination with respect to the two
methods considered separately."
