text: Quantum kinetically constrained models have recently attracted significant
attention due to their anomalous dynamics and thermalization. In this work, we
introduce a hitherto unexplored family of kinetically constrained models featuring
conserved particle number and strong inversion-symmetry breaking due to facilitated
hopping. We demonstrate that these models provide a generic example of so-called
quantum Hilbert space fragmentation, that is manifested in disconnected sectors
in the Hilbert space that are not apparent in the computational basis. Quantum
Hilbert space fragmentation leads to an exponential in system size number of eigenstates
with exactly zero entanglement entropy across several bipartite cuts. These eigenstates
can be probed dynamically using quenches from simple initial product states. In
addition, we study the particle spreading under unitary dynamics launched from
the domain wall state, and find faster than diffusive dynamics at high particle
densities, that crosses over into logarithmically slow relaxation at smaller densities.
Using a classically simulable cellular automaton, we reproduce the logarithmic
dynamics observed in the quantum case. Our work suggests that particle conserving
constrained models with inversion symmetry breaking realize so far unexplored
dynamical behavior and invite their further theoretical and experimental studies.

text: Lateral roots are typically maintained at non-vertical angles with respect
to gravity. These gravitropic setpoint angles are intriguing because their maintenance
requires that roots are able to effect growth response both with and against the
gravity vector, a phenomenon previously attributed to gravitropism acting against
an antigravitropic offset mechanism. Here we show how the components mediating
gravitropism in the vertical primary root—PINs and phosphatases acting upon them—are
reconfigured in their regulation such that lateral root growth at a range of angles
can be maintained. We show that the ability of Arabidopsis lateral roots to bend
both downward and upward requires the generation of auxin asymmetries and is driven
by angle-dependent variation in downward gravitropic auxin flux acting against
angle-independent upward, antigravitropic flux. Further, we demonstrate a symmetry
in auxin distribution in lateral roots at gravitropic setpoint angle that can
be traced back to a net, balanced polarization of PIN3 and PIN7 auxin transporters
in the columella. These auxin fluxes are shifted by altering PIN protein phosphoregulation
in the columella, either by introducing PIN3 phosphovariant versions or via manipulation
of levels of the phosphatase subunit PP2A/RCN1. Finally, we show that auxin, in
addition to driving lateral root directional growth, acts within the lateral root
columella to induce more vertical growth by increasing RCN1 levels, causing a
downward shift in PIN3 localization, thereby diminishing the magnitude of the
upward, antigravitropic auxin flux.

text: Flows through pipes and channels are, in practice, almost always turbulent,
and the multiscale eddying motion is responsible for a major part of the encountered
friction losses and pumping costs1. Conversely, for pulsatile flows, in particular
for aortic blood flow, turbulence levels remain low despite relatively large peak
velocities. For aortic blood flow, high turbulence levels are intolerable as they
would damage the shear-sensitive endothelial cell layer2,3,4,5. Here we show that
turbulence in ordinary pipe flow is diminished if the flow is driven in a pulsatile
mode that incorporates all the key features of the cardiac waveform. At Reynolds
numbers comparable to those of aortic blood flow, turbulence is largely inhibited,
whereas at much higher speeds, the turbulent drag is reduced by more than 25%.
This specific operation mode is more efficient when compared with steady driving,
which is the present situation for virtually all fluid transport processes ranging
from heating circuits to water, gas and oil pipelines.

text: We propose a simple method to measure nonlinear Kerr refractive index in mid-infrared
frequency range that avoids using sophisticated infrared detectors. Our approach
is based on using a near-infrared probe beam which interacts with a mid-IR beam
via wavelength-non-degenerate cross-phase modulation (XPM). By carefully measuring
XPM-induced spectral modifications in the probe beam and comparing the experimental
data with simulation results, we extract the value for the non-degenerate Kerr
index. Finally, in order to obtain the value of degenerate mid-IR Kerr index,
we use the well-established two-band formalism of Sheik-Bahae et al., which is
shown to become particularly simple in the limit of low frequencies. The proposed
technique is complementary to the conventional techniques, such as z-scan, and
has the advantage of not requiring any mid-infrared detectors.

text: The total energy of an eigenstate in a composite quantum system tends to be
distributed equally among its constituents. We identify the quantum fluctuation
around this equipartition principle in the simplest disordered quantum system
consisting of linear combinations of Wigner matrices. As our main ingredient,
we prove the Eigenstate Thermalisation Hypothesis and Gaussian fluctuation for
general quadratic forms of the bulk eigenvectors of Wigner matrices with an arbitrary
deformation.

text: We study the Hamilton cycle problem with input a random graph G ~ G(n,p) in
two different settings. In the first one, G is given to us in the form of randomly
ordered adjacency lists while in the second one, we are given the adjacency matrix
of G. In each of the two settings we derive a deterministic algorithm that w.h.p.
either finds a Hamilton cycle or returns a certificate that such a cycle does
not exist for p = p(n) ≥ 0. The running times of our algorithms are O(n) and respectively,
each being best possible in its own setting.

text: For a locally finite set in R2, the order-k Brillouin tessellations form an
infinite sequence of convex face-to-face tilings of the plane. If the set is coarsely
dense and generic, then the corresponding infinite sequences of minimum and maximum
angles are both monotonic in k. As an example, a stationary Poisson point process
in R2 is locally finite, coarsely dense, and generic with probability one. For
such a set, the distributions of angles in the Voronoi tessellations, Delaunay
mosaics, and Brillouin tessellations are independent of the order and can be derived
from the formula for angles in order-1 Delaunay mosaics given by Miles (Math.
Biosci. 6, 85–127 (1970)).

text: To navigate through diverse tissues, migrating cells must balance persistent
self-propelled motion with adaptive behaviors to circumvent obstacles. We identify
a curvature-sensing mechanism underlying obstacle evasion in immune-like cells.
Specifically, we propose that actin polymerization at the advancing edge of migrating
cells is inhibited by the curvature-sensitive BAR domain protein Snx33 in regions
with inward plasma membrane curvature. The genetic perturbation of this machinery
reduces the cells’ capacity to evade obstructions combined with faster and more
persistent cell migration in obstacle-free environments. Our results show how
cells can read out their surface topography and utilize actin and plasma membrane
biophysics to interpret their environment, allowing them to adaptively decide
if they should move ahead or turn away. On the basis of our findings, we propose
that the natural diversity of BAR domain proteins may allow cells to tune their
curvature sensing machinery to match the shape characteristics in their environment.

text: Whether one considers swarming insects, flocking birds, or bacterial colonies,
collective motion arises from the coordination of individuals and entails the
adjustment of their respective velocities. In particular, in close confinements,
such as those encountered by dense cell populations during development or regeneration,
collective migration can only arise coordinately. Yet, how individuals unify their
velocities is often not understood. Focusing on a finite number of cells in circular
confinements, we identify waves of polymerizing actin that function as a pacemaker
governing the speed of individual cells. We show that the onset of collective
motion coincides with the synchronization of the wave nucleation frequencies across
the population. Employing a simpler and more readily accessible mechanical model
system of active spheres, we identify the synchronization of the individuals’
internal oscillators as one of the essential requirements to reach the corresponding
collective state. The mechanical ‘toy’ experiment illustrates that the global
synchronous state is achieved by nearest neighbor coupling. We suggest by analogy
that local coupling and the synchronization of actin waves are essential for the
emergent, self-organized motion of cell collectives.

text: "Motivated by recent applications to entropy theory in dynamical systems,
we generalise notions introduced by Matthews and define weakly weighted and componentwise
weakly weighted (generalised) quasi-metrics. We then systematise and extend to
full generality the correspondences between these objects and other structures
arising in theoretical computer science and dynamics. In particular, we study
the correspondences with weak partial metrics and, if the underlying space is
a semilattice, with invariant (generalised) quasi-metrics satisfying the descending
path condition, and with strictly monotone semi(-co-)valuations.\r\nWe conclude
discussing, for endomorphisms of generalised quasi-metric semilattices, a generalisation
of both the known intrinsic semilattice entropy and the semigroup entropy."

text: Mitochondrial networks remodel their connectivity, content, and subcellular
localization to support optimized energy production in conditions of increased
environmental or cellular stress. Microglia rely on mitochondria to respond to
these stressors, however our knowledge about mitochondrial networks and their
adaptations in microglia in vivo is limited. Here, we generate a mouse model that
selectively labels mitochondria in microglia. We identify that mitochondrial networks
are more fragmented with increased content and perinuclear localization in vitro
vs. in vivo. Mitochondrial networks adapt similarly in microglia closest to the
injury site after optic nerve crush. Preventing microglial UCP2 increase after
injury by selective knockout induces cellular stress. This results in mitochondrial
hyperfusion in male microglia, a phenotype absent in females due to circulating
estrogens. Our results establish the foundation for mitochondrial network analysis
of microglia in vivo, emphasizing the importance of mitochondrial-based sex effects
of microglia in other pathologies.

text: We introduce extension-based proofs, a class of impossibility proofs that
includes valency arguments. They are modelled as an interaction between a prover
and a protocol. Using proofs based on combinatorial topology, it has been shown
that it is impossible to deterministically solve -set agreement among processes
or approximate agreement on a cycle of length 4 among processes in a wait-free
manner in asynchronous models where processes communicate using objects that can
be constructed from shared registers. However, it was unknown whether proofs based
on simpler techniques were possible. We show that these impossibility results
cannot be obtained by extension-based proofs in the iterated snapshot model and,
hence, extension-based proofs are limited in power.

text: "Superconductivity has many important applications ranging from levitating
trains over qubits to MRI scanners. The phenomenon is successfully modeled by
Bardeen-Cooper-Schrieffer (BCS) theory. From a mathematical perspective, BCS theory
has been studied extensively for systems without boundary. However, little is
known in the presence of boundaries. With the help of numerical methods physicists
observed that the critical temperature may increase in the presence of a boundary.
The goal of this thesis is to understand the influence of boundaries on the critical
temperature in BCS theory and to give a first rigorous justification of these
observations. On the way, we also study two-body Schrödinger operators on domains
with boundaries and prove additional results for superconductors without boundary.\r\n\r\nBCS
theory is based on a non-linear functional, where the minimizer indicates whether
the system is superconducting or in the normal, non-superconducting state. By
considering the Hessian of the BCS functional at the normal state, one can analyze
whether the normal state is possibly a minimum of the BCS functional and estimate
the critical temperature. The Hessian turns out to be a linear operator resembling
a Schrödinger operator for two interacting particles, but with more complicated
kinetic energy. As a first step, we study the two-body Schrödinger operator in
the presence of boundaries.\r\nFor Neumann boundary conditions, we prove that
the addition of a boundary can create new eigenvalues, which correspond to the
two particles forming a bound state close to the boundary.\r\n\r\nSecond, we need
to understand superconductivity in the translation invariant setting. While in
three dimensions this has been extensively studied, there is no mathematical literature
for the one and two dimensional cases. In dimensions one and two, we compute the
weak coupling asymptotics of the critical temperature and the energy gap in the
translation invariant setting. We also prove that their ratio is independent of
the microscopic details of the model in the weak coupling limit; this property
is referred to as universality.\r\n\r\nIn the third part, we study the critical
temperature of superconductors in the presence of boundaries. We start by considering
the one-dimensional case of a half-line with contact interaction. Then, we generalize
the results to generic interactions and half-spaces in one, two and three dimensions.
Finally, we compare the critical temperature of a quarter space in two dimensions
to the critical temperatures of a half-space and of the full space."

text: 'Branching morphogenesis is a ubiquitous process that gives rise to high exchange
surfaces in the vasculature and epithelial organs. Lymphatic capillaries form
branched networks, which play a key role in the circulation of tissue fluid and
immune cells. Although mouse models and correlative patient data indicate that
the lymphatic capillary density directly correlates with functional output, i.e.,
tissue fluid drainage and trafficking efficiency of dendritic cells, the mechanisms
ensuring efficient tissue coverage remain poorly understood. Here, we use the
mouse ear pinna lymphatic vessel network as a model system and combine lineage-tracing,
genetic perturbations, whole-organ reconstructions and theoretical modeling to
show that the dermal lymphatic capillaries tile space in an optimal, space-filling
manner. This coverage is achieved by two complementary mechanisms: initial tissue
invasion provides a non-optimal global scaffold via self-organized branching morphogenesis,
while VEGF-C dependent side-branching from existing capillaries rapidly optimizes
local coverage by directionally targeting low-density regions. With these two
ingredients, we show that a minimal biophysical model can reproduce quantitatively
whole-network reconstructions, across development and perturbations. Our results
show that lymphatic capillary networks can exploit local self-organizing mechanisms
to achieve tissue-scale optimization.'

text: We report on a simple surfactant/template free chemical route for the synthesis
of semi-polycrystalline polyaniline-graphite (SPani-graphite) composite and its
application as an electroactive material in electrochemical charge storage. The
synthesized material exhibits well-defined poly-crystallographic lattices in high
resolution transmission electron micrographs and sharp peaks in x-ray diffraction
spectra suggesting crystalline nature of the material. The specific capacitance
computed from the galvanostatic charge-discharge (GCD) data obtained from 3-electrode
cell configuration using 1 M aq. Na2SO4 as an electrolyte was 111.4 F g−1 at a
current density of 0.1 A g−1 which rises to 269 F g−1 at an elevated current density
of 1.0 A g−1. A similar pattern of increase in the specific capacitance values
with an increase in the current density was observed in the results obtained from
2-electrode symmetric device configuration using polymer gel electrolyte (xanthan
gum in 1 M aq. Na2SO4). The specific capacitance computed from the GCD data obtained
from the device configuration was 20 F g−1 at the current density of 1.0 A g−1.
The device delivers an energy density of 1.7 Wh kg−1 and a power density of 2.48
kWh kg−1 at an applied current density of 0.5 A g−1 suggesting an excellent rate
capability and power management. In addition, the device exhibits ⁓92 % specific
capacitance retention up to 8000 continuous GCD cycles and ⁓80 % coulombic efficiency
up to 10,000 continuous GCD cycles indicating excellent cycling stability. The
unique feature of increasing specific capacitance with respect to applied current
density is attributed to the presence of semi-polycrystalline phases in the SPani-graphite
matrix. The material behaves as a surface redox supercapacitor and its unique
mechanism of charge storage is discussed in detail in the article.

text: "We consider the problem of computing the maximal probability of satisfying
an \r\n-regular specification for stochastic, continuous-state, nonlinear systems
evolving in discrete time. The problem reduces, after automata-theoretic constructions,
to finding the maximal probability of satisfying a parity condition on a (possibly
hybrid) state space. While characterizing the exact satisfaction probability is
open, we show that a lower bound on this probability can be obtained by (I) computing
an under-approximation of the qualitative winning region, i.e., states from which
the parity condition can be enforced almost surely, and (II) computing the maximal
probability of reaching this qualitative winning region.\r\nThe heart of our approach
is a technique to symbolically compute the under-approximation of the qualitative
winning region in step (I) via a finite-state abstraction of the original system
as a \r\n-player parity game. Our abstraction procedure uses only the support
of the probabilistic evolution; it does not use precise numerical transition probabilities.
We prove that the winning set in the abstract -player game induces an under-approximation
of the qualitative winning region in the original synthesis problem, along with
a policy to solve it. By combining these contributions with (a) a symbolic fixpoint
algorithm to solve \r\n-player games and (b) existing techniques for reachability
policy synthesis in stochastic nonlinear systems, we get an abstraction-based
algorithm for finding a lower bound on the maximal satisfaction probability.\r\nWe
have implemented the abstraction-based algorithm in Mascot-SDS, where we combined
the outlined abstraction step with our tool Genie (Majumdar et al., 2023) that
solves \r\n-player parity games (through a reduction to Rabin games) more efficiently
than existing algorithms. We evaluated our implementation on the nonlinear model
of a perturbed bistable switch from the literature. We show empirically that the
lower bound on the winning region computed by our approach is precise, by comparing
against an over-approximation of the qualitative winning region. Moreover, our
implementation outperforms a recently proposed tool for solving this problem by
a large margin."
acknowledgement: "We thank Daniel Hausmann and Nir Piterman for their valuable comments
on an earlier version of the manuscript of our other paper [22] where we present,
among other things, the parity fixpoint for 2 1/2-player games (for a slightly more
general class of games) with a different and indirect proof of correctness. Based
on their comments we observed that, unlike the other fixpoints that we present in
[22], the parity fixpoint does not follow the exact same structure as its counterpart
for 2-player games, which we also use int his paper.\r\nWe also thank Thejaswini
Raghavan for observing that our symbolic parity fixpoint algorithm can be solved
in quasi-polynomial time using recent improved algorithms for solving \r\n-calculus
expressions. This significantly improved the complexity bounds of our algorithm
in this paper.\r\nThe work of R. Majumdar and A.-K. Schmuck are partially supported

text: "Background: \r\nPro-apoptotic BAX is a central mediator of retinal ganglion
cell (RGC) death after optic nerve damage. BAX activation occurs in two stages
including translocation of latent BAX to the mitochondrial outer membrane (MOM)
and then permeabilization of the MOM to facilitate the release of apoptotic signaling
molecules. As a critical component of RGC death, BAX is an attractive target for
neuroprotective therapies and an understanding of the kinetics of BAX activation
and the mechanisms controlling the two stages of this process in RGCs is potentially
valuable in informing the development of a neuroprotective strategy.\r\nMethods:\r\nThe
kinetics of BAX translocation were assessed by both static and live-cell imaging
of a GFP-BAX fusion protein introduced into RGCs using AAV2-mediated gene transfer
in mice. Activation of BAX was achieved using an acute optic nerve crush (ONC)
protocol. Live-cell imaging of GFP-BAX was achieved using explants of mouse retina
harvested 7 days after ONC. Kinetics of translocation in RGCs were compared to
GFP-BAX translocation in 661W tissue culture cells. Permeabilization of GFP-BAX
was assessed by staining with the 6A7 monoclonal antibody, which recognizes a
conformational change in this protein after MOM insertion. Assessment of individual
kinases associated with both stages of activation was made using small molecule
inhibitors injected into the vitreous either independently or in concert with
ONC surgery. The contribution of the Dual Leucine Zipper-JUN-N-Terminal Kinase
cascade was evaluated using mice with a double conditional knock-out of both Mkk4
and Mkk7.\r\nResults:\r\nONC induces the translocation of GFP-BAX in RGCs at a
slower rate and with less intracellular synchronicity than 661W cells, but exhibits
less variability among mitochondrial foci within a single cell. GFP-BAX was also
found to translocate in all compartments of an RGC including the dendritic arbor
and axon. Approximately 6% of translocating RGCs exhibited retrotranslocation
of BAX immediately following translocation. Unlike tissue culture cells, which
exhibit simultaneous translocation and permeabilization, RGCs exhibited a significant
delay between these two stages, similar to detached cells undergoing anoikis.
Translocation, with minimal permeabilization could be induced in a subset of RGCs
using an inhibitor of Focal Adhesion Kinase (PF573228). Permeabilization after
ONC, in a majority of RGCs, could be inhibited with a broad spectrum kinase inhibitor
(sunitinib) or a selective inhibitor for p38/MAPK14 (SB203580). Intervention of
DLK-JNK axis signaling abrogated GFP-BAX translocation after ONC.\r\nConclusions:\r\nA
comparison between BAX activation kinetics in tissue culture cells and in cells
of a complex tissue environment shows distinct differences indicating that caution
should be used when translating findings from one condition to the other. RGCs
exhibit both a delay between translocation and permeabilization and the ability
for translocated BAX to be retrotranslocated, suggesting several stages at which
intervention of the activation process could be exploited in the design of a therapeutic
strategy."

text: Alpha oscillations are a distinctive feature of the awake resting state of
the human brain. However, their functional role in resting-state neuronal dynamics
remains poorly understood. Here we show that, during resting wakefulness, alpha
oscillations drive an alternation of attenuation and amplification bouts in neural
activity. Our analysis indicates that inhibition is activated in pulses that last
for a single alpha cycle and gradually suppress neural activity, while excitation
is successively enhanced over a few alpha cycles to amplify neural activity. Furthermore,
we show that long-term alpha amplitude fluctuations—the “waxing and waning” phenomenon—are
an attenuation-amplification mechanism described by a power-law decay of the activity
rate in the “waning” phase. Importantly, we do not observe such dynamics during
non-rapid eye movement (NREM) sleep with marginal alpha oscillations. The results
suggest that alpha oscillations modulate neural activity not only through pulses
of inhibition (pulsed inhibition hypothesis) but also by timely enhancement of
excitation (or disinhibition).

text: We introduce hypernode automata as a new specification formalism for hyperproperties
of concurrent systems. They are finite automata with nodes labeled with hypernode
logic formulas and transitions labeled with actions. A hypernode logic formula
specifies relations between sequences of variable values in different system executions.
Unlike HyperLTL, hypernode logic takes an asynchronous view on execution traces
by constraining the values and the order of value changes of each variable without
correlating the timing of the changes. Different execution traces are synchronized
solely through the transitions of hypernode automata. Hypernode automata naturally
combine asynchronicity at the node level with synchronicity at the transition
level. We show that the model-checking problem for hypernode automata is decidable
over action-labeled Kripke structures, whose actions induce transitions of the
specification automata. For this reason, hypernode automaton is a suitable formalism
for specifying and verifying asynchronous hyperproperties, such as declassifying
observational determinism in multi-threaded programs.
