text: The high processing cost, poor mechanical properties and moderate performance
of Bi2Te3–based alloys used in thermoelectric devices limit the cost-effectiveness
of this energy conversion technology. Towards solving these current challenges,
in the present work, we detail a low temperature solution-based approach to produce
Bi2Te3-Cu2-xTe nanocomposites with improved thermoelectric performance. Our approach
consists in combining proper ratios of colloidal nanoparticles and to consolidate
the resulting mixture into nanocomposites using a hot press. The transport properties
of the nanocomposites are characterized and compared with those of pure Bi2Te3
nanomaterials obtained following the same procedure. In contrast with most previous
works, the presence of Cu2-xTe nanodomains does not result in a significant reduction
of the lattice thermal conductivity of the reference Bi2Te3 nanomaterial, which
is already very low. However, the introduction of Cu2-xTe yields a nearly threefold
increase of the power factor associated to a simultaneous increase of the Seebeck
coefficient and electrical conductivity at temperatures above 400 K. Taking into
account the band alignment of the two materials, we rationalize this increase
by considering that Cu2-xTe nanostructures, with a relatively low electron affinity,
are able to inject electrons into Bi2Te3, enhancing in this way its electrical
conductivity. The simultaneous increase of the Seebeck coefficient is related
to the energy filtering of charge carriers at energy barriers within Bi2Te3 domains
associated with the accumulation of electrons in regions nearby a Cu2-xTe/Bi2Te3
heterojunction. Overall, with the incorporation of a proper amount of Cu2-xTe
nanoparticles, we demonstrate a 250% improvement of the thermoelectric figure
of merit of Bi2Te3.

text: Copper chalcogenides are outstanding thermoelectric materials for applications
in the medium-high temperature range. Among different chalcogenides, while Cu2−xSe
is characterized by higher thermoelectric figures of merit, Cu2−xS provides advantages
in terms of low cost and element abundance. In the present work, we investigate
the effect of different dopants to enhance the Cu2−xS performance and also its
thermal stability. Among the tested options, Pb-doped Cu2−xS shows the highest
improvement in stability against sulfur volatilization. Additionally, Pb incorporation
allows tuning charge carrier concentration, which enables a significant improvement
of the power factor. We demonstrate here that the introduction of an optimal additive
amount of just 0.3% results in a threefold increase of the power factor in the
middle-temperature range (500–800 K) and a record dimensionless thermoelectric
figure of merit above 2 at 880 K.

text: Assemblies of actin and its regulators underlie the dynamic morphology of
all eukaryotic cells. To understand how actin regulatory proteins work together
to generate actin-rich structures such as filopodia, we analyzed the localization
of diverse actin regulators within filopodia in Drosophila embryos and in a complementary
in vitro system of filopodia-like structures (FLSs). We found that the composition
of the regulatory protein complex where actin is incorporated (the filopodial
tip complex) is remarkably heterogeneous both in vivo and in vitro. Our data reveal
that different pairs of proteins correlate with each other and with actin bundle
length, suggesting the presence of functional subcomplexes. This is consistent
with a theoretical framework where three or more redundant subcomplexes join the
tip complex stochastically, with any two being sufficient to drive filopodia formation.
We provide an explanation for the observed heterogeneity and suggest that a mechanism
based on multiple components allows stereotypical filopodial dynamics to arise
from diverse upstream signaling pathways.

text: We establish finite time extinction with probability one for weak solutions
of the Cauchy–Dirichlet problem for the 1D stochastic porous medium equation with
Stratonovich transport noise and compactly supported smooth initial datum. Heuristically,
this is expected to hold because Brownian motion has average spread rate O(t12)
whereas the support of solutions to the deterministic PME grows only with rate
O(t1m+1). The rigorous proof relies on a contraction principle up to time-dependent
shift for Wong–Zakai type approximations, the transformation to a deterministic
PME with two copies of a Brownian path as the lateral boundary, and techniques
from the theory of viscosity solutions.

the treatment of the noise term). The issue is resolved in this version.

text: We consider inertial iteration methods for Fermat–Weber location problem and
primal–dual three-operator splitting in real Hilbert spaces. To do these, we first
obtain weak convergence analysis and nonasymptotic O(1/n) convergence rate of
the inertial Krasnoselskii–Mann iteration for fixed point of nonexpansive operators
in infinite dimensional real Hilbert spaces under some seemingly easy to implement
conditions on the iterative parameters. One of our contributions is that the convergence
analysis and rate of convergence results are obtained using conditions which appear
not complicated and restrictive as assumed in other previous related results in
the literature. We then show that Fermat–Weber location problem and primal–dual
three-operator splitting are special cases of fixed point problem of nonexpansive
mapping and consequently obtain the convergence analysis of inertial iteration
methods for Fermat–Weber location problem and primal–dual three-operator splitting
in real Hilbert spaces. Some numerical implementations are drawn from primal–dual
three-operator splitting to support the theoretical analysis.

text: Embryo morphogenesis is impacted by dynamic changes in tissue material properties,
which have been proposed to occur via processes akin to phase transitions (PTs).
Here, we show that rigidity percolation provides a simple and robust theoretical
framework to predict material/structural PTs of embryonic tissues from local cell
connectivity. By using percolation theory, combined with directly monitoring dynamic
changes in tissue rheology and cell contact mechanics, we demonstrate that the
zebrafish blastoderm undergoes a genuine rigidity PT, brought about by a small
reduction in adhesion-dependent cell connectivity below a critical value. We quantitatively
predict and experimentally verify hallmarks of PTs, including power-law exponents
and associated discontinuities of macroscopic observables. Finally, we show that
this uniform PT depends on blastoderm cells undergoing meta-synchronous divisions
causing random and, consequently, uniform changes in cell connectivity. Collectively,
our theoretical and experimental findings reveal the structural basis of material
PTs in an organismal context.

text: Given a locally finite X⊆Rd and a radius r≥0, the k-fold cover of X and r
consists of all points in Rd that have k or more points of X within distance r.
We consider two filtrations—one in scale obtained by fixing k and increasing r,
and the other in depth obtained by fixing r and decreasing k—and we compute the
persistence diagrams of both. While standard methods suffice for the filtration
in scale, we need novel geometric and topological concepts for the filtration
in depth. In particular, we introduce a rhomboid tiling in Rd+1 whose horizontal
integer slices are the order-k Delaunay mosaics of X, and construct a zigzag module
of Delaunay mosaics that is isomorphic to the persistence module of the multi-covers.

text: We consider a system of N bosons in the mean-field scaling regime for a class
of interactions including the repulsive Coulomb potential. We derive an asymptotic
expansion of the low-energy eigenstates and the corresponding energies, which
provides corrections to Bogoliubov theory to any order in 1/N.

text: "Background: To understand information coding in single neurons, it is necessary
to analyze subthreshold synaptic events, action potentials (APs), and their interrelation
in different behavioral states. However, detecting excitatory postsynaptic potentials
(EPSPs) or currents (EPSCs) in behaving animals remains challenging, because of
unfavorable signal-to-noise ratio, high frequency, fluctuating amplitude, and
variable time course of synaptic events.\r\nNew method: We developed a method
for synaptic event detection, termed MOD (Machine-learning Optimal-filtering Detection-procedure),
which combines concepts of supervised machine learning and optimal Wiener filtering.
Experts were asked to manually score short epochs of data. The algorithm was trained
to obtain the optimal filter coefficients of a Wiener filter and the optimal detection
threshold. Scored and unscored data were then processed with the optimal filter,
and events were detected as peaks above threshold.\r\nResults: We challenged MOD
with EPSP traces in vivo in mice during spatial navigation and EPSC traces in
vitro in slices under conditions of enhanced transmitter release. The area under
the curve (AUC) of the receiver operating characteristics (ROC) curve was, on
average, 0.894 for in vivo and 0.969 for in vitro data sets, indicating high detection
accuracy and efficiency.\r\nComparison with existing methods: When benchmarked
using a (1 − AUC)−1 metric, MOD outperformed previous methods (template-fit, deconvolution,
and Bayesian methods) by an average factor of 3.13 for in vivo data sets, but
showed comparable (template-fit, deconvolution) or higher (Bayesian) computational
efficacy.\r\nConclusions: MOD may become an important new tool for large-scale,
real-time analysis of synaptic activity."

text: In nerve cells the genes encoding for α2δ subunits of voltage-gated calcium
channels have been linked to synaptic functions and neurological disease. Here
we show that α2δ subunits are essential for the formation and organization of
glutamatergic synapses. Using a cellular α2δ subunit triple-knockout/knockdown
model, we demonstrate a failure in presynaptic differentiation evidenced by defective
presynaptic calcium channel clustering and calcium influx, smaller presynaptic
active zones, and a strongly reduced accumulation of presynaptic vesicle-associated
proteins (synapsin and vGLUT). The presynaptic defect is associated with the downscaling
of postsynaptic AMPA receptors and the postsynaptic density. The role of α2δ isoforms
as synaptic organizers is highly redundant, as each individual α2δ isoform can
rescue presynaptic calcium channel trafficking and expression of synaptic proteins.
Moreover, α2δ-2 and α2δ-3 with mutated metal ion-dependent adhesion sites can
fully rescue presynaptic synapsin expression but only partially calcium channel
trafficking, suggesting that the regulatory role of α2δ subunits is independent
from its role as a calcium channel subunit. Our findings influence the current
view on excitatory synapse formation. First, our study suggests that postsynaptic
differentiation is secondary to presynaptic differentiation. Second, the dependence
of presynaptic differentiation on α2δ implicates α2δ subunits as potential nucleation
points for the organization of synapses. Finally, our results suggest that α2δ
subunits act as transsynaptic organizers of glutamatergic synapses, thereby aligning
the synaptic active zone with the postsynaptic density.

text: Lateral root (LR) formation is an example of a plant post-embryonic organogenesis
event. LRs are issued from non-dividing cells entering consecutive steps of formative
divisions, proliferation and elongation. The chromatin remodeling protein PICKLE
(PKL) negatively regulates auxin-mediated LR formation through a mechanism that
is not yet known. Here we show that PKL interacts with RETINOBLASTOMA-RELATED
1 (RBR1) to repress the LATERAL ORGAN BOUNDARIES-DOMAIN 16 (LBD16) promoter activity.
Since LBD16 function is required for the formative division of LR founder cells,
repression mediated by the PKL–RBR1 complex negatively regulates formative division
and LR formation. Inhibition of LR formation by PKL–RBR1 is counteracted by auxin,
indicating that, in addition to auxin-mediated transcriptional responses, the
fine-tuned process of LR formation is also controlled at the chromatin level in
an auxin-signaling dependent manner.

text: We revise a previous result about the Fröhlich dynamics in the strong coupling
limit obtained in Griesemer (Rev Math Phys 29(10):1750030, 2017). In the latter
it was shown that the Fröhlich time evolution applied to the initial state φ0⊗ξα,
where φ0 is the electron ground state of the Pekar energy functional and ξα the
associated coherent state of the phonons, can be approximated by a global phase
for times small compared to α2. In the present note we prove that a similar approximation
holds for t=O(α2) if one includes a nontrivial effective dynamics for the phonons
that is generated by an operator proportional to α−2 and quadratic in creation
and annihilation operators. Our result implies that the electron ground state
remains close to its initial state for times of order α2, while the phonon fluctuations
around the coherent state ξα can be described by a time-dependent Bogoliubov transformation.

text: 'Polaritons with directional in-plane propagation and ultralow losses in van
der Waals (vdW) crystals promise unprecedented manipulation of light at the nanoscale.
However, these polaritons present a crucial limitation: their directional propagation
is intrinsically determined by the crystal structure of the host material, imposing
forbidden directions of propagation. Here, we demonstrate that directional polaritons
(in-plane hyperbolic phonon polaritons) in a vdW crystal (α-phase molybdenum trioxide)
can be directed along forbidden directions by inducing an optical topological
transition, which emerges when the slab is placed on a substrate with a given
negative permittivity (4H–silicon carbide). By visualizing the transition in real
space, we observe exotic polaritonic states between mutually orthogonal hyperbolic
regimes, which unveil the topological origin of the transition: a gap opening
in the dispersion. This work provides insights into optical topological transitions
in vdW crystals, which introduce a route to direct light at the nanoscale.'

text: 'Various degenerate diffusion equations exhibit a waiting time phenomenon:
depending on the “flatness” of the compactly supported initial datum at the boundary
of the support, the support of the solution may not expand for a certain amount
of time. We show that this phenomenon is captured by particular Lagrangian discretizations
of the porous medium and the thin film equations, and we obtain sufficient criteria
for the occurrence of waiting times that are consistent with the known ones for
the original PDEs. For the spatially discrete solution, the waiting time phenomenon
refers to a deviation of the edge of support from its original position by a quantity
comparable to the mesh width, over a mesh-independent time interval. Our proof
is based on estimates on the fluid velocity in Lagrangian coordinates. Combining
weighted entropy estimates with an iteration technique à la Stampacchia leads
to upper bounds on free boundary propagation. Numerical simulations show that
the phenomenon is already clearly visible for relatively coarse discretizations.'

text: We consider the stochastic quantization of a quartic double-well energy functional
in the semiclassical regime and derive optimal asymptotics for the exponentially
small splitting of the ground state energy. Our result provides an infinite-dimensional
version of some sharp tunneling estimates known in finite dimensions for semiclassical
Witten Laplacians in degree zero. From a stochastic point of view it proves that
the L2 spectral gap of the stochastic one-dimensional Allen-Cahn equation in finite
volume satisfies a Kramers-type formula in the limit of vanishing noise. We work
with finite-dimensional lattice approximations and establish semiclassical estimates
which are uniform in the dimension. Our key estimate shows that the constant separating
the two exponentially small eigenvalues from the rest of the spectrum can be taken
independently of the dimension.

text: Intercellular adhesion is the key to multicellularity, and its malfunction
plays an important role in various developmental and disease-related processes.
Although it has been intensively studied by both biologists and physicists, a
commonly accepted definition of cell-cell adhesion is still being debated. Cell-cell
adhesion has been described at the molecular scale as a function of adhesion receptors
controlling binding affinity, at the cellular scale as resistance to detachment
forces or modulation of surface tension, and at the tissue scale as a regulator
of cellular rearrangements and morphogenesis. In this review, we aim to summarize
and discuss recent advances in the molecular, cellular, and theoretical description
of cell-cell adhesion, ranging from biomimetic models to the complexity of cells
and tissues in an organismal context. In particular, we will focus on cadherin-mediated
cell-cell adhesion and the role of adhesion signaling and mechanosensation therein,
two processes central for understanding the biological and physical basis of cell-cell
adhesion.

text: This paper provides an a priori error analysis of a localized orthogonal decomposition
method for the numerical stochastic homogenization of a model random diffusion
problem. If the uniformly elliptic and bounded random coefficient field of the
model problem is stationary and satisfies a quantitative decorrelation assumption
in the form of the spectral gap inequality, then the expected $L^2$ error of the
method can be estimated, up to logarithmic factors, by $H+(\varepsilon/H)^{d/2}$,
$\varepsilon$ being the small correlation length of the random coefficient and
$H$ the width of the coarse finite element mesh that determines the spatial resolution.
The proof bridges recent results of numerical homogenization and quantitative
stochastic homogenization.
