text: Bacteria divide by binary fission. The protein machine responsible for this
process is the divisome, a transient assembly of more than 30 proteins in and
on the surface of the cytoplasmic membrane. Together, they constrict the cell
envelope and remodel the peptidoglycan layer to eventually split the cell into
two. For Escherichia coli, most molecular players involved in this process have
probably been identified, but obtaining the quantitative information needed for
a mechanistic understanding can often not be achieved from experiments in vivo
alone. Since the discovery of the Z-ring more than 30 years ago, in vitro reconstitution
experiments have been crucial to shed light on molecular processes normally hidden
in the complex environment of the living cell. In this review, we summarize how
rebuilding the divisome from purified components – or at least parts of it - have
been instrumental to obtain the detailed mechanistic understanding of the bacterial
cell division machinery that we have today.

text: De novo heterozygous variants in KCNC2 encoding the voltage-gated potassium
(K+) channel subunit Kv3.2 are a recently described cause of developmental and
epileptic encephalopathy (DEE). A de novo variant in KCNC2 c.374G > A (p.Cys125Tyr)
was identified via exome sequencing in a patient with DEE. Relative to wild-type
Kv3.2, Kv3.2-p.Cys125Tyr induces K+ currents exhibiting a large hyperpolarizing
shift in the voltage dependence of activation, accelerated activation, and delayed
deactivation consistent with a relative stabilization of the open conformation,
along with increased current density. Leveraging the cryogenic electron microscopy
(cryo-EM) structure of Kv3.1, molecular dynamic simulations suggest that a strong
π-π stacking interaction between the variant Tyr125 and Tyr156 in the α-6 helix
of the T1 domain promotes a relative stabilization of the open conformation of
the channel, which underlies the observed gain of function. A multicompartment
computational model of a Kv3-expressing parvalbumin-positive cerebral cortex fast-spiking
γ-aminobutyric acidergic (GABAergic) interneuron (PV-IN) demonstrates how the
Kv3.2-Cys125Tyr variant impairs neuronal excitability and dysregulates inhibition
in cerebral cortex circuits to explain the resulting epilepsy.

text: We study a linear rotor in a bosonic bath within the angulon formalism. Our
focus is on systems where isotropic or anisotropic impurity-boson interactions
support a shallow bound state. To study the fate of the angulon in the vicinity
of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian.
First, we use it to study attractive, spherically symmetric impurity-boson interactions
for which the linear rotor can be mapped onto a static impurity. The well-known
polaron formalism provides an adequate description in this limit. Second, we consider
anisotropic potentials, and show that the presence of a shallow bound state with
pronounced anisotropic character leads to a many-body instability that washes
out the angulon dynamics.

text: Die Quantenrotation ist ein spannendes Phänomen, das in vielen verschiedenen
Systemen auftritt, von Molekülen und Atomen bis hin zu subatomaren Teilchen wie
Neutronen und Protonen. Durch den Einsatz von starken Laserpulsen ist es möglich,
die mathematisch anspruchsvolle Topologie der Rotation von Molekülen aufzudecken
und topologisch geschützte Zustände zu erzeugen, die unerwartetes Verhalten zeigen.
Diese Entdeckungen könnten Auswirkungen auf die Molekülphysik und physikalische
Chemie haben und die Entwicklung neuer Technologien ermöglichen. Die Verbindung
von Quantenrotation und Topologie stellt ein aufregendes, interdisziplinäres Forschungsfeld
dar und bietet neue Wege zur Kontrolle und Nutzung von quantenmechanischen Phänomenen.

text: We perform a stochastic homogenization analysis for composite materials exhibiting
a random microstructure. Under the assumptions of stationarity and ergodicity,
we characterize the Gamma-limit of a micromagnetic energy functional defined on
magnetizations taking value in the unit sphere and including both symmetric and
antisymmetric exchange contributions. This Gamma-limit corresponds to a micromagnetic
energy functional with homogeneous coefficients. We provide explicit formulas
for the effective magnetic properties of the composite material in terms of homogenization
correctors. Additionally, the variational analysis of the two exchange energy
terms is performed in the more general setting of functionals defined on manifold-valued
maps with Sobolev regularity, in the case in which the target manifold is a bounded,
orientable smooth surface with tubular neighborhood of uniform thickness. Eventually,
we present an explicit characterization of minimizers of the effective exchange
in the case of magnetic multilayers, providing quantitative evidence of Dzyaloshinskii’s
predictions on the emergence of helical structures in composite ferromagnetic
materials with stochastic microstructure.

text: It is a basic principle that an effect cannot come before the cause. Dispersive
relations that follow from this fundamental fact have proven to be an indispensable
tool in physics and engineering. They are most powerful in the domain of linear
response where they are known as Kramers-Kronig relations. However, when it comes
to nonlinear phenomena the implications of causality are much less explored, apart
from several notable exceptions. Here in this paper we demonstrate how to apply
the dispersive formalism to analyze the ultrafast nonlinear response in the context
of the paradigmatic nonlinear Kerr effect. We find that the requirement of causality
introduces a noticeable effect even under assumption that Kerr effect is mediated
by quasi-instantaneous off-resonant electronic hyperpolarizability. We confirm
this by experimentally measuring the time-resolved Kerr dynamics in GaAs by means
of a hybrid pump-probe Mach-Zehnder interferometer and demonstrate the presence
of an intrinsic lagging between amplitude and phase responses as predicted by
dispersive analysis. Our results describe a general property of the time-resolved
nonlinear processes thereby highlighting the importance of accounting for dispersive
effects in the nonlinear optical processes involving ultrashort pulses.

text: 'Episodic memories are encoded by experience-activated neuronal ensembles
that remain necessary and sufficient for recall. However, the temporal evolution
of memory engrams after initial encoding is unclear. In this study, we employed
computational and experimental approaches to examine how the neural composition
and selectivity of engrams change with memory consolidation. Our spiking neural
network model yielded testable predictions: memories transition from unselective
to selective as neurons drop out of and drop into engrams; inhibitory activity
during recall is essential for memory selectivity; and inhibitory synaptic plasticity
during memory consolidation is critical for engrams to become selective. Using
activity-dependent labeling, longitudinal calcium imaging and a combination of
optogenetic and chemogenetic manipulations in mouse dentate gyrus, we conducted
contextual fear conditioning experiments that supported our model’s predictions.
Our results reveal that memory engrams are dynamic and that changes in engram
composition mediated by inhibitory plasticity are crucial for the emergence of
memory selectivity.'

text: 'A face in a curve arrangement is called popular if it is bounded by the same
curve multiple times. Motivated by the automatic generation of curved nonogram
puzzles, we investigate possibilities to eliminate the popular faces in an arrangement
by inserting a single additional curve. This turns out to be NP-hard; however,
it becomes tractable when the number of popular faces is small: We present a probabilistic
FPT-approach in the number of popular faces.'

text: In this paper we investigate locally free representations of a quiver Q over
a commutative Frobenius algebra R by arithmetic Fourier transform. When the base
field is finite we prove that the number of isomorphism classes of absolutely
indecomposable locally free representations of fixed rank is independent of the
orientation of Q. We also prove that the number of isomorphism classes of locally
free absolutely indecomposable representations of the preprojective algebra of
Q over R equals the number of isomorphism classes of locally free absolutely indecomposable
representations of Q over R[t]/(t2). Using these results together with results
of Geiss, Leclerc and Schröer we give, when k is algebraically closed, a classification
of pairs (Q, R) such that the set of isomorphism classes of indecomposable locally
free representations of Q over R is finite. Finally when the representation is
free of rank 1 at each vertex of Q, we study the function that counts the number
of isomorphism classes of absolutely indecomposable locally free representations
of Q over the Frobenius algebra Fq[t]/(tr). We prove that they are polynomial
in q and their generating function is rational and satisfies a functional equation.

text: The huge antlers of the extinct Irish elk have invited evolutionary speculation
since Darwin. In the 1970s, Stephen Jay Gould presented the first extensive data
on antler size in the Irish elk and combined these with comparative data from
other deer to test the hypothesis that the gigantic antlers were the outcome of
a positive allometry that constrained large-bodied deer to have proportionally
even larger antlers. He concluded that the Irish elk had antlers as predicted
for its size and interpreted this within his emerging framework of developmental
constraints as an explanatory factor in evolution. Here we reanalyze antler allometry
based on new morphometric data for 57 taxa of the family Cervidae. We also present
a new phylogeny for the Cervidae, which we use for comparative analyses. In contrast
to Gould, we find that the antlers of Irish elk were larger than predicted from
the allometry within the true deer, Cervini, as analyzed by Gould, but follow
the allometry across Cervidae as a whole. After dissecting the discrepancy, we
reject the allometric-constraint hypothesis because, contrary to Gould, we find
no similarity between static and evolutionary allometries, and because we document
extensive non-allometric evolution of antler size across the Cervidae.

text: Centrioles are part of centrosomes and cilia, which are microtubule organising
centres (MTOC) with diverse functions. Despite their stability, centrioles can
disappear during differentiation, such as in oocytes, but little is known about
the regulation of their structural integrity. Our previous research revealed that
the pericentriolar material (PCM) that surrounds centrioles and its recruiter,
Polo kinase, are downregulated in oogenesis and sufficient for maintaining both
centrosome structural integrity and MTOC activity. We now show that the expression
of specific components of the centriole cartwheel and wall, including ANA1/CEP295,
is essential for maintaining centrosome integrity. We find that Polo kinase requires
ANA1 to promote centriole stability in cultured cells and eggs. In addition, ANA1
expression prevents the loss of centrioles observed upon PCM-downregulation. However,
the centrioles maintained by overexpressing and tethering ANA1 are inactive, unlike
the MTOCs observed upon tethering Polo kinase. These findings demonstrate that
several centriole components are needed to maintain centrosome structure. Our
study also highlights that centrioles are more dynamic than previously believed,
with their structural stability relying on the continuous expression of multiple
components.

text: We prove a version of the tamely ramified geometric Langlands correspondence
in positive characteristic for GLn(k). Let k be an algebraically closed field
of characteristic p>n. Let X be a smooth projective curve over k with marked points,
and fix a parabolic subgroup of GLn(k) at each marked point. We denote by Bunn,P
the moduli stack of (quasi-)parabolic vector bundles on X, and by Locn,P the moduli
stack of parabolic flat connections such that the residue is nilpotent with respect
to the parabolic reduction at each marked point. We construct an equivalence between
the bounded derived category Db(Qcoh(Loc0n,P)) of quasi-coherent sheaves on an
open substack Loc0n,P⊂Locn,P, and the bounded derived category Db(D0Bunn,P-mod)
of D0Bunn,P-modules, where D0Bunn,P is a localization of DBunn,P the sheaf of
crystalline differential operators on Bunn,P. Thus we extend the work of Bezrukavnikov-Braverman
to the tamely ramified case. We also prove a correspondence between flat connections
on X with regular singularities and meromorphic Higgs bundles on the Frobenius
twist X(1) of X with first order poles .

text: "The lattice Schwinger model, the discrete version of QED in \r\n1\r\n+\r\n1\r\n
dimensions, is a well-studied test bench for lattice gauge theories. Here, we
study the fractal properties of this model. We reveal the self-similarity of the
ground state, which allows us to develop a recurrent procedure for finding the
ground-state wave functions and predicting ground-state energies. We present the
results of recurrently calculating ground-state wave functions using the fractal
Ansatz and automized software package for fractal image processing. In certain
parameter regimes, just a few terms are enough for our recurrent procedure to
predict ground-state energies close to the exact ones for several hundreds of
sites. Our findings pave the way to understanding the complexity of calculating
many-body wave functions in terms of their fractal properties as well as finding
new links between condensed matter and high-energy lattice models."

text: Magnetic frustration allows to access novel and intriguing properties of magnetic
systems and has been explored mainly in planar triangular-like arrays of magnetic
ions. In this work, we describe the phosphide Ce6Ni6P17, where the Ce+3 ions accommodate
in a body-centered cubic lattice of Ce6 regular octahedra. From measurements of
magnetization, specific heat, and resistivity, we determine a rich phase diagram
as a function of temperature and magnetic field in which different magnetic phases
are found. Besides clear evidence of magnetic frustration is obtained from entropy
analysis. At zero field, a second-order antiferromagnetic transition occurs at
TN1≈1 K followed by a first-order transition at TN2≈0.45 K. With magnetic field
new magnetic phases appear, including a weakly first-order transition which ends
in a classical critical point and a third magnetic phase. We also study the exact
solution of the spin-1/2 Heisenberg model in an octahedron which allows us a qualitative
understanding of the phase diagram and compare with the experimental results.

text: The impulsive limit (the “sudden approximation”) has been widely employed
to describe the interaction between molecules and short, far-off-resonant laser
pulses. This approximation assumes that the timescale of the laser-molecule interaction
is significantly shorter than the internal rotational period of the molecule,
resulting in the rotational motion being instantaneously “frozen” during the interaction.
This simplified description of the laser-molecule interaction is incorporated
in various theoretical models predicting rotational dynamics of molecules driven
by short laser pulses. In this theoretical work, we develop an effective theory
for ultrashort laser pulses by examining the full time-evolution operator and
solving the time-dependent Schrödinger equation at the operator level. Our findings
reveal a critical angular momentum, lcrit, at which the impulsive limit breaks
down. In other words, the validity of the sudden approximation depends not only
on the pulse duration but also on its intensity, since the latter determines how
many angular momentum states are populated. We explore both ultrashort multicycle
(Gaussian) pulses and the somewhat less studied half-cycle pulses, which produce
distinct effective potentials. We discuss the limitations of the impulsive limit
and propose a method that rescales the effective matrix elements, enabling an
improved and more accurate description of laser-molecule interactions.

text: Graphical games are a useful framework for modeling the interactions of (selfish)
agents who are connected via an underlying topology and whose behaviors influence
each other. They have wide applications ranging from computer science to economics
and biology. Yet, even though an agent’s payoff only depends on the actions of
their direct neighbors in graphical games, computing the Nash equilibria and making
statements about the convergence time of "natural" local dynamics in particular
can be highly challenging. In this work, we present a novel approach for classifying
complexity of Nash equilibria in graphical games by establishing a connection
to local graph algorithms, a subfield of distributed computing. In particular,
we make the observation that the equilibria of graphical games are equivalent
to locally verifiable labelings (LVL) in graphs; vertex labelings which are verifiable
with constant-round local algorithms. This connection allows us to derive novel
lower bounds on the convergence time to equilibrium of best-response dynamics
in graphical games. Since we establish that distributed convergence can sometimes
be provably slow, we also introduce and give bounds on an intuitive notion of
"time-constrained" inefficiency of best responses. We exemplify how our results
can be used in the implementation of mechanisms that ensure convergence of best
responses to a Nash equilibrium. Our results thus also give insight into the convergence
of strategy-proof algorithms for graphical games, which is still not well understood.

text: Traditional blockchains grant the miner of a block full control not only over
which transactions but also their order. This constitutes a major flaw discovered
with the introduction of decentralized finance and allows miners to perform MEV
attacks. In this paper, we address the issue of sandwich attacks by providing
a construction that takes as input a blockchain protocol and outputs a new blockchain
protocol with the same security but in which sandwich attacks are not profitable.
Furthermore, our protocol is fully decentralized with no trusted third parties
or heavy cryptography primitives and carries a linear increase in latency and
minimum computation overhead.

text: "Oblivious routing is a well-studied paradigm that uses static precomputed
routing tables for selecting routing paths within a network. Existing oblivious
routing schemes with polylogarithmic competitive ratio for general networks are
tree-based, in the sense that routing is performed according to a convex combination
of trees. However, this restriction to trees leads to a construction that has
time quadratic in the size of the network and does not parallelize well. \r\nIn
this paper we study oblivious routing schemes based on electrical routing. In
particular, we show that general networks with n vertices and m edges admit a
routing scheme that has competitive ratio O(log² n) and consists of a convex combination
of only O(√m) electrical routings. This immediately leads to an improved construction
algorithm with time Õ(m^{3/2}) that can also be implemented in parallel with
Õ(√m) depth."

text: We consider quadratic forms of deterministic matrices A evaluated at the random
eigenvectors of a large N×N GOE or GUE matrix, or equivalently evaluated at the
columns of a Haar-orthogonal or Haar-unitary random matrix. We prove that, as
long as the deterministic matrix has rank much smaller than √N, the distributions
of the extrema of these quadratic forms are asymptotically the same as if the
eigenvectors were independent Gaussians. This reduces the problem to Gaussian
computations, which we carry out in several cases to illustrate our result, finding
Gumbel or Weibull limiting distributions depending on the signature of A. Our
result also naturally applies to the eigenvectors of any invariant ensemble.

text: The GNOM (GN) Guanine nucleotide Exchange Factor for ARF small GTPases (ARF-GEF)
is among the best studied trafficking regulators in plants, playing crucial and
unique developmental roles in patterning and polarity. The current models place
GN at the Golgi apparatus (GA), where it mediates secretion/recycling, and at
the plasma membrane (PM) presumably contributing to clathrin-mediated endocytosis
(CME). The mechanistic basis of the developmental function of GN, distinct from
the other ARF-GEFs including its closest homologue GNOM-LIKE1 (GNL1), remains
elusive. Insights from this study largely extend the current notions of GN function.
We show that GN, but not GNL1, localizes to the cell periphery at long-lived structures
distinct from clathrin-coated pits, while CME and secretion proceed normally in
gn knockouts. The functional GN mutant variant GNfewerroots,
absent from the GA, suggests that the cell periphery is the major site of GN action
responsible for its developmental function. Following inhibition by Brefeldin
A, GN, but not GNL1, relocates to the PM likely on exocytic vesicles, suggesting
selective molecular associations en route to the cell periphery. A study of GN-GNL1
chimeric ARF-GEFs indicates that all GN domains contribute to the specific GN
function in a partially redundant manner. Together, this study offers significant
steps toward the elucidation of the mechanism underlying unique cellular and development
functions of GNOM.
