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.
