text: Electrodepositing insulating lithium peroxide (Li2O2) is the key process during
discharge of aprotic Li–O2 batteries and determines rate, capacity, and reversibility.
Current understanding states that the partition between surface adsorbed and dissolved
lithium superoxide governs whether Li2O2 grows as a conformal surface film or
larger particles, leading to low or high capacities, respectively. However, better
understanding governing factors for Li2O2 packing density and capacity requires
structural sensitive in situ metrologies. Here, we establish in situ small- and
wide-angle X-ray scattering (SAXS/WAXS) as a suitable method to record the Li2O2
phase evolution with atomic to submicrometer resolution during cycling a custom-built
in situ Li–O2 cell. Combined with sophisticated data analysis, SAXS allows retrieving
rich quantitative structural information from complex multiphase systems. Surprisingly,
we find that features are absent that would point at a Li2O2 surface film formed
via two consecutive electron transfers, even in poorly solvating electrolytes
thought to be prototypical for surface growth. All scattering data can be modeled
by stacks of thin Li2O2 platelets potentially forming large toroidal particles.
Li2O2 solution growth is further justified by rotating ring-disk electrode measurements
and electron microscopy. Higher discharge overpotentials lead to smaller Li2O2
particles, but there is no transition to an electronically passivating, conformal
Li2O2 coating. Hence, mass transport of reactive species rather than electronic
transport through a Li2O2 film limits the discharge capacity. Provided that species
mobilities and carbon surface areas are high, this allows for high discharge capacities
even in weakly solvating electrolytes. The currently accepted Li–O2 reaction mechanism
ought to be reconsidered.

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.

as well as helpful discussions. Special thanks go to F. Cornalba for suggesting
the additional κ-truncation in Proposition 5. I am also indebted to an anonymous
referee for pointing out a gap in a previous version of the proof of Lemma 9 (concerning
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: 'Quantum entanglement has been generated and verified in cold-atom experiments
and used to make atom-interferometric measurements below the shot-noise limit.
However, current state-of-the-art cold-atom devices exploit separable (i.e., unentangled)
atomic states. This perspective piece asks the question: can entanglement usefully
improve cold-atom sensors, in the sense that it gives new sensing capabilities
unachievable with current state-of-the-art devices? We briefly review the state-of-the-art
in precision cold-atom sensing, focusing on clocks and inertial sensors, identifying
the potential benefits entanglement could bring to these devices, and the challenges
that need to be overcome to realize these benefits. We survey demonstrated methods
of generating metrologically useful entanglement in cold-atom systems, note their
relative strengths and weaknesses, and assess their prospects for near-to-medium
term quantum-enhanced cold-atom sensing.'

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: '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: Mentorship is experience and/or knowledge‐based guidance. Mentors support,
sponsor and advocate for mentees. Having one or more mentors when you seek advice
can significantly influence and improve your research endeavours, well‐being and
career development. Positive mentee–mentor relationships are vital for maintaining
work–life balance and success in careers. Early‐career researchers (ECRs), in
particular, can benefit from mentorship to navigate challenges in academic and
nonacademic life and careers. Yet, strategies for selecting mentors and maintaining
interactions with them are often underdiscussed within research environments.
In this Words of Advice, we provide recommendations for ECRs to seek and manage
mentorship interactions. Our article draws from our experiences as ECRs and published
work, to provide suggestions for mentees to proactively promote beneficial mentorship
interactions. The recommended practices highlight the importance of identifying
mentorship needs, planning and selecting multiple and diverse mentors, setting
goals, and maintaining constructive, and mutually beneficial working relationships
with mentors.

text: Modeling a crystal as a periodic point set, we present a fingerprint consisting
of density functionsthat facilitates the efficient search for new materials and
material properties. We prove invarianceunder isometries, continuity, and completeness
in the generic case, which are necessary featuresfor the reliable comparison of
crystals. The proof of continuity integrates methods from discretegeometry and
lattice theory, while the proof of generic completeness combines techniques fromgeometry
with analysis. The fingerprint has a fast algorithm based on Brillouin zones and
relatedinclusion-exclusion formulae. We have implemented the algorithm and describe
its application tocrystal structure prediction.

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.
