text: "Animals exhibit a variety of behavioural defences against socially transmitted
parasites. These defences evolved to increase host fitness by avoiding, resisting
or tolerating infection.\r\nBecause they can occur in both infected individuals
and their uninfected social partners, these defences often have important consequences
for the social group.\r\nHere, we discuss the evolution and ecology of anti-parasite
behavioural defences across a taxonomically wide social spectrum, considering
colonial groups, stable groups, transitional groups and solitary animals.\r\nWe
discuss avoidance, resistance and tolerance behaviours across these social group
structures, identifying how social complexity, group composition and interdependent
social relationships may contribute to the expression and evolution of behavioural
strategies.\r\nFinally, we outline avenues for further investigation such as approaches
to quantify group-level responses, and the connection of the physiological and
behavioural response to parasites in different social contexts."

text: AMPA glutamate receptors (AMPARs) mediate excitatory neurotransmission throughout
the brain. Their signalling is uniquely diversified by brain region-specific auxiliary
subunits, providing an opportunity for the development of selective therapeutics.
AMPARs associated with TARP γ8 are enriched in the hippocampus, and are targets
of emerging anti-epileptic drugs. To understand their therapeutic activity, we
determined cryo-EM structures of the GluA1/2-γ8 receptor associated with three
potent, chemically diverse ligands. We find that despite sharing a lipid-exposed
and water-accessible binding pocket, drug action is differentially affected by
binding-site mutants. Together with patch-clamp recordings and MD simulations
we also demonstrate that ligand-triggered reorganisation of the AMPAR-TARP interface
contributes to modulation. Unexpectedly, one ligand (JNJ-61432059) acts bifunctionally,
negatively affecting GluA1 but exerting positive modulatory action on GluA2-containing
AMPARs, in a TARP stoichiometry-dependent manner. These results further illuminate
the action of TARPs, demonstrate the sensitive balance between positive and negative
modulatory action, and provide a mechanistic platform for development of both
positive and negative selective AMPAR modulators.

text: Experiments have shown that charge distributions of granular materials are
non-Gaussian, with broad tails that indicate many particles with high charge.
This observation has consequences for the behavior of granular materials in many
settings, and may bear relevance to the underlying charge transfer mechanism.
However, there is the unaddressed possibility that broad tails arise due to experimental
uncertainties, as determining the shapes of tails is nontrivial. Here we show
that measurement uncertainties can indeed account for most of the tail broadening
previously observed. The clue that reveals this is that distributions are sensitive
to the electric field at which they are measured; ones measured at low (high)
fields have larger (smaller) tails. Accounting for sources of uncertainty, we
reproduce this broadening in silico. Finally, we use our results to back out the
true charge distribution without broadening, which we find is still non-Guassian,
though with substantially different behavior at the tails and indicating significantly
fewer highly charged particles. These results have implications in many natural
settings where electrostatic interactions, especially among highly charged particles,
strongly affect granular behavior.

text: Motivated by the recent discoveries of superconductivity in bilayer and trilayer
graphene, we theoretically investigate superconductivity and other interaction-driven
phases in multilayer graphene stacks. To this end, we study the density of states
of multilayer graphene with up to four layers at the single-particle band structure
level in the presence of a transverse electric field. Among the considered structures,
tetralayer graphene with rhombohedral (ABCA) stacking reaches the highest density
of states. We study the phases that can arise in ABCA graphene by tuning the carrier
density and transverse electric field. For a broad region of the tuning parameters,
the presence of strong Coulomb repulsion leads to a spontaneous spin and valley
symmetry breaking via Stoner transitions. Using a model that incorporates the
spontaneous spin and valley polarization, we explore the Kohn-Luttinger mechanism
for superconductivity driven by repulsive Coulomb interactions. We find that the
strongest superconducting instability is in the p-wave channel, and occurs in
proximity to the onset of Stoner transitions. Interestingly, we find a range of
densities and transverse electric fields where superconductivity develops out
of a strongly corrugated, singly connected Fermi surface in each valley, leading
to a topologically nontrivial chiral p+ip superconducting state with an even number
of copropagating chiral Majorana edge modes. Our work establishes ABCA-stacked
tetralayer graphene as a promising platform for observing strongly correlated
physics and topological superconductivity.

text: We investigate the capabilities of Physics-Informed Neural Networks (PINNs)
to reconstruct turbulent Rayleigh–Bénard flows using only temperature information.
We perform a quantitative analysis of the quality of the reconstructions at various
amounts of low-passed-filtered information and turbulent intensities. We compare
our results with those obtained via nudging, a classical equation-informed data
assimilation technique. At low Rayleigh numbers, PINNs are able to reconstruct
with high precision, comparable to the one achieved with nudging. At high Rayleigh
numbers, PINNs outperform nudging and are able to achieve satisfactory reconstruction
of the velocity fields only when data for temperature is provided with high spatial
and temporal density. When data becomes sparse, the PINNs performance worsens,
not only in a point-to-point error sense but also, and contrary to nudging, in
a statistical sense, as can be seen in the probability density functions and energy
spectra.

text: In the physics literature the spectral form factor (SFF), the squared Fourier
transform of the empirical eigenvalue density, is the most common tool to test
universality for disordered quantum systems, yet previous mathematical results
have been restricted only to two exactly solvable models (Forrester in J Stat
Phys 183:33, 2021. https://doi.org/10.1007/s10955-021-02767-5, Commun Math Phys
387:215–235, 2021. https://doi.org/10.1007/s00220-021-04193-w). We rigorously
prove the physics prediction on SFF up to an intermediate time scale for a large
class of random matrices using a robust method, the multi-resolvent local laws.
Beyond Wigner matrices we also consider the monoparametric ensemble and prove
that universality of SFF can already be triggered by a single random parameter,
supplementing the recently proven Wigner–Dyson universality (Cipolloni et al.
in Probab Theory Relat Fields, 2021. https://doi.org/10.1007/s00440-022-01156-7)
to larger spectral scales. Remarkably, extensive numerics indicates that our formulas
correctly predict the SFF in the entire slope-dip-ramp regime, as customarily
called in physics.

text: The multicellular organization of diverse systems, including embryos, intestines,
and tumors relies on coordinated cell migration in curved environments. In these
settings, cells establish supracellular patterns of motion, including collective
rotation and invasion. While such collective modes have been studied extensively
in flat systems, the consequences of geometrical and topological constraints on
collective migration in curved systems are largely unknown. Here, we discover
a collective mode of cell migration in rotating spherical tissues manifesting
as a propagating single-wavelength velocity wave. This wave is accompanied by
an apparently incompressible supracellular flow pattern featuring topological
defects as dictated by the spherical topology. Using a minimal active particle
model, we reveal that this collective mode arises from the effect of curvature
on the active flocking behavior of a cell layer confined to a spherical surface.
Our results thus identify curvature-induced velocity waves as a mode of collective
cell migration, impacting the dynamical organization of 3D curved tissues.

text: 'Reaching a high cavity population with a coherent pump in the strong-coupling
regime of a single-atom laser is impossible due to the photon blockade effect.
In this Letter, we experimentally demonstrate that in a single-atom maser based
on a transmon strongly coupled to two resonators, it is possible to pump over
a dozen photons into the system. The first high-quality resonator plays the role
of a usual lasing cavity, and the second one presents a controlled dissipation
channel, bolstering population inversion, and modifies the energy-level structure
to lift the blockade. As confirmation of the lasing action, we observe conventional
laser features such as a narrowing of the emission linewidth and external signal
amplification. Additionally, we report unique single-atom features: self-quenching
and several lasing thresholds.'

text: "Disulfide bond formation is fundamentally important for protein structure,
and constitutes a key mechanism by which cells regulate the intracellular oxidation
state. Peroxiredoxins (PRDXs) eliminate reactive oxygen species such as hydrogen
peroxide through a catalytic cycle of Cys oxidation and reduction. Additionally,
upon Cys oxidation PRDXs undergo extensive conformational rearrangements that
may underlie their presently structurally poorly defined functions as molecular
chaperones. Rearrangements include high molecular-weight oligomerization, the
dynamics of which are, however, poorly understood, as is the impact of disulfide
bond formation on these properties. Here we show that formation of disulfide bonds
along the catalytic cycle induces extensive microsecond time scale dynamics, as
monitored by magic-angle spinning NMR of the 216 kDa-large Tsa1 decameric assembly
and solution-NMR of a designed dimeric mutant. We ascribe the conformational dynamics
to structural frustration, resulting from conflicts between the disulfide-constrained
reduction of mobility and the desire to fulfil other favorable contacts. \r\n\r\nThis

text: Gears and cogwheels are elemental components of machines. They restrain degrees
of freedom and channel power into a specified motion. Building and powering small-scale
cogwheels are key steps toward feasible micro and nanomachinery. Assembly, energy
injection, and control are, however, a challenge at the microscale. In contrast
with passive gears, whose function is to transmit torques from one to another,
interlocking and untethered active gears have the potential to unveil dynamics
and functions untapped by externally driven mechanisms. Here, it is shown the
assembly and control of a family of self-spinning cogwheels with varying teeth
numbers and study the interlocking of multiple cogwheels. The teeth are formed
by colloidal microswimmers that power the structure. The cogwheels are autonomous
and active, showing persistent rotation. Leveraging the angular momentum of optical
vortices, we control the direction of rotation of the cogwheels. The pairs of
interlocking and active cogwheels that roll over each other in a random walk and
have curvature-dependent mobility are studied. This behavior is leveraged to self-position
parts and program microbots, demonstrating the ability to pick up, direct, and
release a load. The work constitutes a step toward autonomous machinery with external
control as well as (re)programmable microbots and matter.

text: The deployment of direct formate fuel cells (DFFCs) relies on the development
of active and stable catalysts for the formate oxidation reaction (FOR). Palladium,
providing effective full oxidation of formate to CO2, has been widely used as
FOR catalyst, but it suffers from low stability, moderate activity, and high cost.
Herein, we detail a colloidal synthesis route for the incorporation of P on Pd2Sn
nanoparticles. These nanoparticles are dispersed on carbon black and the obtained
composite is used as electrocatalytic material for the FOR. The Pd2Sn0.8P-based
electrodes present outstanding catalytic activities with record mass current densities
up to 10.0 A mgPd-1, well above those of Pd1.6Sn/C reference electrode. These
high current densities are further enhanced by increasing the temperature from
25 °C to 40 °C. The Pd2Sn0.8P electrode also allows for slowing down the rapid
current decay that generally happens during operation and can be rapidly re-activated
through potential cycling. The excellent catalytic performance obtained is rationalized
using density functional theory (DFT) calculations.

text: Interstitial fluid (IF) accumulation between embryonic cells is thought to
be important for embryo patterning and morphogenesis. Here, we identify a positive
mechanical feedback loop between cell migration and IF relocalization and find
that it promotes embryonic axis formation during zebrafish gastrulation. We show
that anterior axial mesendoderm (prechordal plate [ppl]) cells, moving in between
the yolk cell and deep cell tissue to extend the embryonic axis, compress the
overlying deep cell layer, thereby causing IF to flow from the deep cell layer
to the boundary between the yolk cell and the deep cell layer, directly ahead
of the advancing ppl. This IF relocalization, in turn, facilitates ppl cell protrusion
formation and migration by opening up the space into which the ppl moves and,
thereby, the ability of the ppl to trigger IF relocalization by pushing against
the overlying deep cell layer. Thus, embryonic axis formation relies on a hydraulic
feedback loop between cell migration and IF relocalization.

text: The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations
of a many-body bath, can be used to describe an impurity rotating in a fluid or
solid environment. Here, we propose a coherent state ansatz in the co-rotating
frame, which provides a comprehensive theoretical description of angulons. We
reveal the quasiparticle properties, such as energies, quasiparticle weights,
and spectral functions, and show that our ansatz yields a persistent decrease
in the impurity’s rotational constant due to many-body dressing, which is consistent
with experimental observations. From our study, a picture of the angulon emerges
as an effective spin interacting with a magnetic field that is self-consistently
generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy,
which focuses on the response of rotating molecules to a laser perturbation in
the linear response regime. Importantly, we take into account initial-state interactions
that have been neglected in prior studies and reveal their impact on the excitation
spectrum. To examine the angulon instability regime, we use a single-excitation
ansatz and obtain results consistent with experiments, in which a broadening of
spectral lines is observed while phonon wings remain highly suppressed due to
initial-state interactions.

text: The development of cost-effective, high-activity and stable bifunctional catalysts
for the oxygen reduction and evolution reactions (ORR/OER) is essential for zinc–air
batteries (ZABs) to reach the market. Such catalysts must contain multiple adsorption/reaction
sites to cope with the high demands of reversible oxygen electrodes. Herein, we
propose a high entropy alloy (HEA) based on relatively abundant elements as a
bifunctional ORR/OER catalyst. More specifically, we detail the synthesis of a
CrMnFeCoNi HEA through a low-temperature solution-based approach. Such HEA displays
superior OER performance with an overpotential of 265 mV at a current density
of 10 mA/cm2, and a 37.9 mV/dec Tafel slope, well above the properties of a standard
commercial catalyst based on RuO2. This high performance is partially explained
by the presence of twinned defects, the incidence of large lattice distortions,
and the electronic synergy between the different components, being Cr key to decreasing
the energy barrier of the OER rate-determining step. CrMnFeCoNi also displays
superior ORR performance with a half-potential of 0.78 V and an onset potential
of 0.88 V, comparable with commercial Pt/C. The potential gap (Egap) between the
OER overpotential and the ORR half-potential of CrMnFeCoNi is just 0.734 V. Taking
advantage of these outstanding properties, ZABs are assembled using the CrMnFeCoNi
HEA as air cathode and a zinc foil as the anode. The assembled cells provide an
open-circuit voltage of 1.489 V, i.e. 90% of its theoretical limit (1.66 V), a
peak power density of 116.5 mW/cm2, and a specific capacity of 836 mAh/g that
stays stable for more than 10 days of continuous cycling, i.e. 720 cycles @ 8
mA/cm2 and 16.6 days of continuous cycling, i.e. 1200 cycles @ 5 mA/cm2.

text: 'The input to the token swapping problem is a graph with vertices v1, v2,
. . . , vn, and n tokens with labels 1,2, . . . , n, one on each vertex. The goal
is to get token i to vertex vi for all i= 1, . . . , n using a minimum number
of swaps, where a swap exchanges the tokens on the endpoints of an edge.Token
swapping on a tree, also known as “sorting with a transposition tree,” is not
known to be in P nor NP-complete. We present some partial results: 1. An optimum
swap sequence may need to perform a swap on a leaf vertex that has the correct
token (a “happy leaf”), disproving a conjecture of Vaughan. 2. Any algorithm that
fixes happy leaves—as all known approximation algorithms for the problem do—has
approximation factor at least 4/3. Furthermore, the two best-known 2-approximation
algorithms have approximation factor exactly 2. 3. A generalized problem—weighted
coloured token swapping—is NP-complete on trees, but solvable in polynomial time
on paths and stars. In this version, tokens and vertices have colours, and colours
have weights. The goal is to get every token to a vertex of the same colour, and
the cost of a swap is the sum of the weights of the two tokens involved.'

text: Coherent control and manipulation of quantum degrees of freedom such as spins
forms the basis of emerging quantum technologies. In this context, the robust
valley degree of freedom and the associated valley pseudospin found in two-dimensional
transition metal dichalcogenides is a highly attractive platform. Valley polarization
and coherent superposition of valley states have been observed in these systems
even up to room temperature. Control of valley coherence is an important building
block for the implementation of valley qubit. Large magnetic fields or high-power
lasers have been used in the past to demonstrate the control (initialization and
rotation) of the valley coherent states. Here, the control of layer–valley coherence
via strong coupling of valley excitons in bilayer WS2 to microcavity photons is
demonstrated by exploiting the pseudomagnetic field arising in optical cavities
owing to the transverse electric–transverse magnetic (TE–TM)mode splitting. The
use of photonic structures to generate pseudomagnetic fields which can be used
to manipulate exciton-polaritons presents an attractive approach to control optical
responses without the need for large magnets or high-intensity optical pump powers.

text: We study the problem of high-dimensional multiple packing in Euclidean space.
Multiple packing is a natural generalization of sphere packing and is defined
as follows. Let N > 0 and L ∈ Z ≽2 . A multiple packing is a set C of points in
R n such that any point in R n lies in the intersection of at most L – 1 balls
of radius √ nN around points in C . Given a well-known connection with coding
theory, multiple packings can be viewed as the Euclidean analog of list-decodable
codes, which are well-studied for finite fields. In this paper, we derive the
best known lower bounds on the optimal density of list-decodable infinite constellations
for constant L under a stronger notion called average-radius multiple packing.
To this end, we apply tools from high-dimensional geometry and large deviation
theory.

text: Universal nonequilibrium properties of isolated quantum systems are typically
probed by studying transport of conserved quantities, such as charge or spin,
while transport of energy has received considerably less attention. Here, we study
infinite-temperature energy transport in the kinetically constrained PXP model
describing Rydberg atom quantum simulators. Our state-of-the-art numerical simulations,
including exact diagonalization and time-evolving block decimation methods, reveal
the existence of two distinct transport regimes. At moderate times, the energy-energy
correlation function displays periodic oscillations due to families of eigenstates
forming different su(2) representations hidden within the spectrum. These families
of eigenstates generalize the quantum many-body scarred states found in previous
works and leave an imprint on the infinite-temperature energy transport. At later
times, we observe a long-lived superdiffusive transport regime that we attribute
to the proximity of a nearby integrable point. While generic strong deformations
of the PXP model indeed restore diffusive transport, adding a strong chemical
potential intriguingly gives rise to a well-converged superdiffusive exponent
z≈3/2. Our results suggest constrained models to be potential hosts of novel transport
regimes and call for developing an analytic understanding of their energy transport.

text: "The main idea behind BUBAAK is to run multiple program analyses in parallel
and use runtime monitoring and enforcement to observe and control their progress
in real time. The analyses send information about (un)explored states of the program
and discovered invariants to a monitor. The monitor processes the received data
and can force an analysis to stop the search of certain program parts (which have
already been analyzed by other analyses), or to make it utilize a program invariant
found by another analysis.\r\nAt SV-COMP 2023, the implementation of data exchange
between the monitor and the analyses was not yet completed, which is why BUBAAK
only ran several analyses in parallel, without any coordination. Still, BUBAAK
won the meta-category FalsificationOverall and placed very well in several other
(sub)-categories of the competition."

text: "As the complexity and criticality of software increase every year, so does
the importance of run-time monitoring. Third-party monitoring, with limited knowledge
of the monitored software, and best-effort monitoring, which keeps pace with the
monitored software, are especially valuable, yet underexplored areas of run-time
monitoring. Most existing monitoring frameworks do not support their combination
because they either require access to the monitored code for instrumentation purposes
or the processing of all observed events, or both.\r\n\r\nWe present a middleware
framework, VAMOS, for the run-time monitoring of software which is explicitly
designed to support third-party and best-effort scenarios. The design goals of
VAMOS are (i) efficiency (keeping pace at low overhead), (ii) flexibility (the
ability to monitor black-box code through a variety of different event channels,
and the connectability to monitors written in different specification languages),
and (iii) ease-of-use. To achieve its goals, VAMOS combines aspects of event broker
and event recognition systems with aspects of stream processing systems.\r\nWe
implemented a prototype toolchain for VAMOS and conducted experiments including
a case study of monitoring for data races. The results indicate that VAMOS enables
writing useful yet efficient monitors, is compatible with a variety of event sources
and monitor specifications, and simplifies key aspects of setting up a monitoring
system from scratch."
