text: AMPA receptor (AMPAR) abundance and positioning at excitatory synapses regulates
the strength of transmission. Changes in AMPAR localisation can enact synaptic
plasticity, allowing long-term information storage, and is therefore tightly controlled.
Multiple mechanisms regulating AMPAR synaptic anchoring have been described, but
with limited coherence or comparison between reports, our understanding of this
process is unclear. Here, combining synaptic recordings from mouse hippocampal
slices and super-resolution imaging in dissociated cultures, we compare the contributions
of three AMPAR interaction domains controlling transmission at hippocampal CA1
synapses. We show that the AMPAR C-termini play only a modulatory role, whereas
the extracellular N-terminal domain (NTD) and PDZ interactions of the auxiliary
subunit TARP γ8 are both crucial, and each is sufficient to maintain transmission.
Our data support a model in which γ8 accumulates AMPARs at the postsynaptic density,
where the NTD further tunes their positioning. This interplay between cytosolic
(TARP γ8) and synaptic cleft (NTD) interactions provides versatility to regulate
synaptic transmission and plasticity.

text: "The numerical simulation of dynamical phenomena in interacting quantum systems
is a notoriously hard problem. Although a number of promising numerical methods
exist, they often have limited applicability due to the growth of entanglement
or the presence of the so-called sign problem. In this work, we develop an importance
sampling scheme for the simulation of quantum spin dynamics, building on a recent
approach mapping quantum spin systems to classical stochastic processes. The importance
sampling scheme is based on identifying the classical trajectory that yields the
largest contribution to a given quantum observable. An exact transformation is
then carried out to preferentially sample trajectories that are close to the dominant
one. We demonstrate that this approach is capable of reducing the temporal growth
of fluctuations in the stochastic quantities, thus extending the range of accessible
times and system sizes compared to direct sampling. We discuss advantages and
limitations of the proposed approach, outlining directions\r\nfor further developments."

text: "There has recently been a surge of interest in the computational and complexity
properties of the population model, which assumes n anonymous, computationally-bounded
nodes, interacting at random, with the goal of jointly computing global predicates.
Significant work has gone towards investigating majority or consensus dynamics
in this model: that is, assuming that every node is initially in one of two states
X or Y, determine which state had higher initial count.\r\n\r\nIn this paper,
we consider a natural generalization of majority/consensus, which we call comparison
: in its simplest formulation, we are given two baseline states, X and Y, present
in any initial configuration in fixed, but possibly small counts. One of these
states has higher count than the other: we will assume |X_0| > C |Y_0| for some
constant C > 1. The challenge is to design a protocol by which nodes can quickly
and reliably decide on which of the baseline states X_0 and Y_0 has higher initial
count. We begin by analyzing a simple and general dynamics solving the above comparison
problem, which uses O( log n ) states per node, and converges in O(log n) (parallel)
time, with high probability, to a state where the whole population votes on opinions
X or Y at rates proportional to the initial concentrations of |X_0| vs. |Y_0|.
We then describe how this procedure can be bootstrapped to solve comparison, i.e.
have every node in the population reach the \"correct'' decision, with probability
1 - o(1), at the cost of O (log log n) additional states. Further, we prove that
this dynamics is self-stabilizing, in the sense that it converges to the correct
decision from arbitrary initial states, and leak-robust, in the sense that it
can withstand spurious faulty reactions, which are known to occur in practical
implementations of population protocols. Our analysis is based on a new martingale
concentration result relating the discrete-time evolution of a population protocol
to its expected (steady-state) analysis, which should be a useful tool when analyzing
opinion dynamics and epidemic dissemination in the population model."

text: The control of many-body quantum dynamics in complex systems is a key challenge
in the quest to reliably produce and manipulate large-scale quantum entangled
states. Recently, quench experiments in Rydberg atom arrays [Bluvstein et al.
Science 371, 1355 (2021)] demonstrated that coherent revivals associated with
quantum many-body scars can be stabilized by periodic driving, generating stable
subharmonic responses over a wide parameter regime. We analyze a simple, related
model where these phenomena originate from spatiotemporal ordering in an effective
Floquet unitary, corresponding to discrete time-crystalline behavior in a prethermal
regime. Unlike conventional discrete time crystals, the subharmonic response exists
only for Néel-like initial states, associated with quantum scars. We predict robustness
to perturbations and identify emergent timescales that could be observed in future
experiments. Our results suggest a route to controlling entanglement in interacting
quantum systems by combining periodic driving with many-body scars.

text: The notion of Thouless energy plays a central role in the theory of Anderson
localization. We investigate and compare the scaling of Thouless energy across
the many-body localization (MBL) transition in a Floquet model. We use a combination
of methods that are reliable on the ergodic side of the transition (e.g., spectral
form factor) and methods that work on the MBL side (e.g., typical matrix elements
of local operators) to obtain a complete picture of the Thouless energy behavior
across the transition. On the ergodic side, Thouless energy decreases slowly with
the system size, while at the transition it becomes comparable to the level spacing.
Different probes yield consistent estimates of Thouless energy in their overlapping
regime of applicability, giving the location of the transition point nearly free
of finite-size drift. This work establishes a connection between different definitions
of Thouless energy in a many-body setting and yields insights into the MBL transition
in Floquet systems.

text: The reflectance field of a face describes the reflectance properties responsible
for complex lighting effects including diffuse, specular, inter-reflection and
self shadowing. Most existing methods for estimating the face reflectance from
a monocular image assume faces to be diffuse with very few approaches adding a
specular component. This still leaves out important perceptual aspects of reflectance
as higher-order global illumination effects and self-shadowing are not modeled.
We present a new neural representation for face reflectance where we can estimate
all components of the reflectance responsible for the final appearance from a
single monocular image. Instead of modeling each component of the reflectance
separately using parametric models, our neural representation allows us to generate
a basis set of faces in a geometric deformation-invariant space, parameterized
by the input light direction, viewpoint and face geometry. We learn to reconstruct
this reflectance field of a face just from a monocular image, which can be used
to render the face from any viewpoint in any light condition. Our method is trained
on a light-stage training dataset, which captures 300 people illuminated with
150 light conditions from 8 viewpoints. We show that our method outperforms existing
monocular reflectance reconstruction methods, in terms of photorealism due to
better capturing of physical premitives, such as sub-surface scattering, specularities,
self-shadows and other higher-order effects.

text: In this article we introduce a complete gradient estimate for symmetric quantum
Markov semigroups on von Neumann algebras equipped with a normal faithful tracial
state, which implies semi-convexity of the entropy with respect to the recently
introduced noncommutative 2-Wasserstein distance. We show that this complete gradient
estimate is stable under tensor products and free products and establish its validity
for a number of examples. As an application we prove a complete modified logarithmic
Sobolev inequality with optimal constant for Poisson-type semigroups on free group
factors.

text: Inhibition or targeted deletion of histone deacetylase 3 (HDAC3) is neuroprotective
in a variety neurodegenerative conditions, including retinal ganglion cells (RGCs)
after acute optic nerve damage. Consistent with this, induced HDAC3 expression
in cultured cells shows selective toxicity to neurons. Despite an established
role for HDAC3 in neuronal pathology, little is known regarding the mechanism
of this pathology.

text: We define quantum equivariant K-theory of Nakajima quiver varieties. We discuss
type A in detail as well as its connections with quantum XXZ spin chains and trigonometric
Ruijsenaars-Schneider models. Finally we study a limit which produces a K-theoretic
version of results of Givental and Kim, connecting quantum geometry of flag varieties
and Toda lattice.
acknowledgement: 'First of all we would like to thank Andrei Okounkov for invaluable
discussions, advises and sharing with us his fantastic viewpoint on modern quantum
geometry. We are also grateful to D. Korb and Z. Zhou for their interest and comments.

text: 'The developmental strategies used by progenitor cells to endure a safe journey
from their induction place towards the site of terminal differentiation are still
poorly understood. Here we uncovered a progenitor cell allocation mechanism that
stems from an incomplete process of epithelial delamination that allows progenitors
to coordinate their movement with adjacent extra-embryonic tissues. Progenitors
of the zebrafish laterality organ originate from the surface epithelial enveloping
layer by an apical constriction process of cell delamination. During this process,
progenitors retain long-term apical contacts that enable the epithelial layer
to pull a subset of progenitors along their way towards the vegetal pole. The
remaining delaminated progenitors follow apically-attached progenitors’ movement
by a co-attraction mechanism, avoiding sequestration by the adjacent endoderm,
ensuring their fate and collective allocation at the differentiation site. Thus,
we reveal that incomplete delamination serves as a cellular platform for coordinated
tissue movements during development. Impact Statement: Incomplete delamination
serves as a cellular platform for coordinated tissue movements during development,
guiding newly formed progenitor cell groups to the differentiation site.'

text: 'We present a faster symbolic algorithm for the following central problem
in probabilistic verification: Compute the maximal end-component (MEC) decomposition
of Markov decision processes (MDPs). This problem generalizes the SCC decomposition
problem of graphs and closed recurrent sets of Markov chains. The model of symbolic
algorithms is widely used in formal verification and model-checking, where access
to the input model is restricted to only symbolic operations (e.g., basic set
operations and computation of one-step neighborhood). For an input MDP with n vertices
and m edges, the classical symbolic algorithm from the 1990s for the MEC decomposition
requires O(n2) symbolic operations and O(1) symbolic space. The only other
symbolic algorithm for the MEC decomposition requires O(nm−−√) symbolic operations
and O(m−−√) symbolic space. A main open question is whether the worst-case O(n2) bound
for symbolic operations can be beaten. We present a symbolic algorithm that requires O˜(n1.5) symbolic
operations and O˜(n−−√) symbolic space. Moreover, the parametrization of our
algorithm provides a trade-off between symbolic operations and symbolic space:
for all 0<ϵ≤1/2 the symbolic algorithm requires O˜(n2−ϵ) symbolic operations
and O˜(nϵ) symbolic space ( O˜ hides poly-logarithmic factors). Using our techniques
we present faster algorithms for computing the almost-sure winning regions of ω
-regular objectives for MDPs. We consider the canonical parity objectives for ω
-regular objectives, and for parity objectives with d -priorities we present
an algorithm that computes the almost-sure winning region with O˜(n2−ϵ) symbolic
operations and O˜(nϵ) symbolic space, for all 0<ϵ≤1/2 .'

text: In this paper, we introduce a random environment for the exclusion process
in obtained by assigning a maximal occupancy to each site. This maximal occupancy
is allowed to randomly vary among sites, and partial exclusion occurs. Under the
assumption of ergodicity under translation and uniform ellipticity of the environment,
we derive a quenched hydrodynamic limit in path space by strengthening the mild
solution approach initiated in Nagy (2002) and Faggionato (2007). To this purpose,
we prove, employing the technology developed for the random conductance model,
a homogenization result in the form of an arbitrary starting point quenched invariance
principle for a single particle in the same environment, which is a result of
independent interest. The self-duality property of the partial exclusion process
allows us to transfer this homogenization result to the particle system and, then,
apply the tightness criterion in Redig et al. (2020).

text: 'Markov chains are the de facto finite-state model for stochastic dynamical
systems, and Markov decision processes (MDPs) extend Markov chains by incorporating
non-deterministic behaviors. Given an MDP and rewards on states, a classical optimization
criterion is the maximal expected total reward where the MDP stops after T steps,
which can be computed by a simple dynamic programming algorithm. We consider a
natural generalization of the problem where the stopping times can be chosen according
to a probability distribution, such that the expected stopping time is T, to optimize
the expected total reward. Quite surprisingly we establish inter-reducibility
of the expected stopping-time problem for Markov chains with the Positivity problem
(which is related to the well-known Skolem problem), for which establishing either
decidability or undecidability would be a major breakthrough. Given the hardness
of the exact problem, we consider the approximate version of the problem: we show
that it can be solved in exponential time for Markov chains and in exponential
space for MDPs.'

text: 'This paper characterizes the latency of the simplified successive-cancellation
(SSC) decoding scheme for polar codes under hardware resource constraints. In
particular, when the number of processing elements P that can perform SSC decoding
operations in parallel is limited, as is the case in practice, the latency of
SSC decoding is O(N1−1 μ+NPlog2log2NP), where N is the block length of the code
and μ is the scaling exponent of polar codes for the channel. Three direct consequences
of this bound are presented. First, in a fully-parallel implementation where P=N2
, the latency of SSC decoding is O(N1−1/μ) , which is sublinear in the block length.
This recovers a result from an earlier work. Second, in a fully-serial implementation
where P=1 , the latency of SSC decoding scales as O(Nlog2log2N) . The multiplicative
constant is also calculated: we show that the latency of SSC decoding when P=1
is given by (2+o(1))Nlog2log2N . Third, in a semi-parallel implementation, the
smallest P that gives the same latency as that of the fully-parallel implementation
is P=N1/μ . The tightness of our bound on SSC decoding latency and the applicability
of the foregoing results is validated through extensive simulations.'

text: The ⊗*-monoidal structure on the category of sheaves on the Ran space is not
pro-nilpotent in the sense of [3]. However, under some connectivity assumptions,
we prove that Koszul duality induces an equivalence of categories and that this
equivalence behaves nicely with respect to Verdier duality on the Ran space and
integrating along the Ran space, i.e. taking factorization homology. Based on
ideas sketched in [4], we show that these results also offer a simpler alternative
to one of the two main steps in the proof of the Atiyah-Bott formula given in
[7] and [5].

text: 'Rab-interacting molecule (RIM)-binding protein 2 (BP2) is a multidomain protein
of the presynaptic active zone (AZ). By binding to RIM, bassoon (Bsn), and voltage-gated
Ca2+ channels (CaV), it is considered to be a central organizer of the topography
of CaV and release sites of synaptic vesicles (SVs) at the AZ. Here, we used RIM-BP2
knock-out (KO) mice and their wild-type (WT) littermates of either sex to investigate
the role of RIM-BP2 at the endbulb of Held synapse of auditory nerve fibers (ANFs)
with bushy cells (BCs) of the cochlear nucleus, a fast relay of the auditory pathway
with high release probability. Disruption of RIM-BP2 lowered release probability
altering short-term plasticity and reduced evoked EPSCs. Analysis of SV pool dynamics
during high-frequency train stimulation indicated a reduction of SVs with high
release probability but an overall normal size of the readily releasable SV pool
(RRP). The Ca2+-dependent fast component of SV replenishment after RRP depletion
was slowed. Ultrastructural analysis by superresolution light and electron microscopy
revealed an impaired topography of presynaptic CaV and a reduction of docked and
membrane-proximal SVs at the AZ. We conclude that RIM-BP2 organizes the topography
of CaV, and promotes SV tethering and docking. This way RIM-BP2 is critical for
establishing a high initial release probability as required to reliably signal
sound onset information that we found to be degraded in BCs of RIM-BP2-deficient
mice in vivo. SIGNIFICANCE STATEMENT: Rab-interacting molecule (RIM)-binding proteins
(BPs) are key organizers of the active zone (AZ). Using a multidisciplinary approach
to the calyceal endbulb of Held synapse that transmits auditory information at
rates of up to hundreds of Hertz with submillisecond precision we demonstrate
a requirement for RIM-BP2 for normal auditory signaling. Endbulb synapses lacking
RIM-BP2 show a reduced release probability despite normal whole-terminal Ca2+
influx and abundance of the key priming protein Munc13-1, a reduced rate of SV
replenishment, as well as an altered topography of voltage-gated (CaV)2.1 Ca2+
channels, and fewer docked and membrane proximal synaptic vesicles (SVs). This
hampers transmission of sound onset information likely affecting downstream neural
computations such as of sound localization.'

text: "Repeated idempotent elements are commonly used to characterise iterable behaviours
in abstract models of computation. Therefore, given a monoid M, it is natural
to ask how long a sequence of elements of M needs to be to ensure the presence
of consecutive idempotent factors. This question is formalised through the notion
of the Ramsey function R_M associated to M, obtained by mapping every k ∈ ℕ to
the minimal integer R_M(k) such that every word u ∈ M^* of length R_M(k) contains
k consecutive non-empty factors that correspond to the same idempotent element
of M. In this work, we study the behaviour of the Ramsey function R_M by investigating
the regular \U0001D49F-length of M, defined as the largest size L(M) of a submonoid
of M isomorphic to the set of natural numbers {1,2, …, L(M)} equipped with the
max operation. We show that the regular \U0001D49F-length of M determines the
degree of R_M, by proving that k^L(M) ≤ R_M(k) ≤ (k|M|⁴)^L(M). To allow applications
of this result, we provide the value of the regular \U0001D49F-length of diverse
monoids. In particular, we prove that the full monoid of n × n Boolean matrices,
which is used to express transition monoids of non-deterministic automata, has
a regular \U0001D49F-length of (n²+n+2)/2."

text: 'The extent to which women differ in the course of blood cell counts throughout
pregnancy, and the importance of these changes to pregnancy outcomes has not been
well defined. Here, we develop a series of statistical analyses of repeated measures
data to reveal the degree to which women differ in the course of pregnancy, predict
the changes that occur, and determine the importance of these changes for post-partum
hemorrhage (PPH) which is one of the leading causes of maternal mortality. We
present a prospective cohort of 4082 births recorded at the University Hospital,
Lausanne, Switzerland between 2009 and 2014 where full labour records could be
obtained, along with complete blood count data taken at hospital admission. We
find significant differences, at a [Formula: see text] level, among women in how
blood count values change through pregnancy for mean corpuscular hemoglobin, mean
corpuscular volume, mean platelet volume, platelet count and red cell distribution
width. We find evidence that almost all complete blood count values show trimester-specific
associations with PPH. For example, high platelet count (OR 1.20, 95% CI 1.01-1.53),
high mean platelet volume (OR 1.58, 95% CI 1.04-2.08), and high erythrocyte levels
(OR 1.36, 95% CI 1.01-1.57) in trimester 1 increased PPH, but high values in trimester
3 decreased PPH risk (OR 0.85, 0.79, 0.67 respectively). We show that differences
among women in the course of blood cell counts throughout pregnancy have an important
role in shaping pregnancy outcome and tracking blood count value changes through
pregnancy improves identification of women at increased risk of postpartum hemorrhage.
This study provides greater understanding of the complex changes in blood count
values that occur through pregnancy and provides indicators to guide the stratification
of patients into risk groups.'

text: Ferromagnetism is most common in transition metal compounds but may also arise
in low-density two-dimensional electron systems, with signatures observed in silicon,
III-V semiconductor systems, and graphene moiré heterostructures. Here we show
that gate-tuned van Hove singularities in rhombohedral trilayer graphene drive
the spontaneous ferromagnetic polarization of the electron system into one or
more spin- and valley flavors. Using capacitance measurements on graphite-gated
van der Waals heterostructures, we find a cascade of density- and electronic displacement
field tuned phase transitions marked by negative electronic compressibility. The
transitions define the boundaries between phases where quantum oscillations have
either four-fold, two-fold, or one-fold degeneracy, associated with a spin and
valley degenerate normal metal, spin-polarized `half-metal', and spin and valley
polarized `quarter metal', respectively. For electron doping, the salient features
are well captured by a phenomenological Stoner model with a valley-anisotropic
Hund's coupling, likely arising from interactions at the lattice scale. For hole
filling, we observe a richer phase diagram featuring a delicate interplay of broken
symmetries and transitions in the Fermi surface topology. Finally, by rotational
alignment of a hexagonal boron nitride substrate to induce a moiré superlattice,
we find that the superlattice perturbs the preexisting isospin order only weakly,
leaving the basic phase diagram intact while catalyzing the formation of topologically
nontrivial gapped states whenever itinerant half- or quarter metal states occur
at half- or quarter superlattice band filling. Our results show that rhombohedral
trilayer graphene is an ideal platform for well-controlled tests of many-body
theory and reveal magnetism in moiré materials to be fundamentally itinerant in
nature.
