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.

text: "We prove that the factorization homologies of a scheme with coefficients
in truncated polynomial algebras compute the cohomologies of its generalized configuration
spaces. Using Koszul duality between commutative algebras and Lie algebras, we
obtain new expressions for the cohomologies of the latter. As a consequence, we
obtain a uniform and conceptual approach for treating homological stability, homological
densities, and arithmetic densities of generalized configuration spaces. Our results
categorify, generalize, and in fact provide a conceptual understanding of the
coincidences appearing in the work of Farb--Wolfson--Wood. Our computation of
the stable homological densities also yields rational homotopy types, answering
a question posed by Vakil--Wood. Our approach hinges on the study of homological
stability of cohomological Chevalley complexes, which is of independent interest.\r\n"

text: The multimeric matrix (M) protein of clinically relevant paramyxoviruses orchestrates
assembly and budding activity of viral particles at the plasma membrane (PM).
We identified within the canine distemper virus (CDV) M protein two microdomains,
potentially assuming α-helix structures, which are essential for membrane budding
activity. Remarkably, while two rationally designed microdomain M mutants (E89R,
microdomain 1 and L239D, microdomain 2) preserved proper folding, dimerization,
interaction with the nucleocapsid protein, localization at and deformation of
the PM, the virus-like particle formation, as well as production of infectious
virions (as monitored using a membrane budding-complementation system), were,
in sharp contrast, strongly impaired. Of major importance, raster image correlation
spectroscopy (RICS) revealed that both microdomains contributed to finely tune
M protein mobility specifically at the PM. Collectively, our data highlighted
the cornerstone membrane budding-priming activity of two spatially discrete M
microdomains, potentially by coordinating the assembly of productive higher oligomers
at the PM.

text: A central goal in systems neuroscience is to understand the functions performed
by neural circuits. Previous top-down models addressed this question by comparing
the behaviour of an ideal model circuit, optimised to perform a given function,
with neural recordings. However, this requires guessing in advance what function
is being performed, which may not be possible for many neural systems. To address
this, we propose an inverse reinforcement learning (RL) framework for inferring
the function performed by a neural network from data. We assume that the responses
of each neuron in a network are optimised so as to drive the network towards ‘rewarded’
states, that are desirable for performing a given function. We then show how one
can use inverse RL to infer the reward function optimised by the network from
observing its responses. This inferred reward function can be used to predict
how the neural network should adapt its dynamics to perform the same function
when the external environment or network structure changes. This could lead to
theoretical predictions about how neural network dynamics adapt to deal with cell
death and/or varying sensory stimulus statistics.

text: Optogenetics has been harnessed to shed new mechanistic light on current and
future therapeutic strategies. This has been to date achieved by the regulation
of ion flow and electrical signals in neuronal cells and neural circuits that
are known to be affected by disease. In contrast, the optogenetic delivery of
trophic biochemical signals, which support cell survival and are implicated in
degenerative disorders, has never been demonstrated in an animal model of disease.
Here, we reengineered the human and Drosophila melanogaster REarranged during
Transfection (hRET and dRET) receptors to be activated by light, creating one-component
optogenetic tools termed Opto-hRET and Opto-dRET. Upon blue light stimulation,
these receptors robustly induced the MAPK/ERK proliferative signaling pathway
in cultured cells. In PINK1B9 flies that exhibit loss of PTEN-induced putative
kinase 1 (PINK1), a kinase associated with familial Parkinson’s disease (PD),
light activation of Opto-dRET suppressed mitochondrial defects, tissue degeneration
and behavioral deficits. In human cells with PINK1 loss-of-function, mitochondrial
fragmentation was rescued using Opto-dRET via the PI3K/NF-кB pathway. Our results
demonstrate that a light-activated receptor can ameliorate disease hallmarks in
a genetic model of PD. The optogenetic delivery of trophic signals is cell type-specific
and reversible and thus has the potential to inspire novel strategies towards
a spatio-temporal regulation of tissue repair.

text: The quality control system for messenger RNA (mRNA) is fundamental for cellular
activities in eukaryotes. To elucidate the molecular mechanism of 3'-Phosphoinositide-Dependent
Protein Kinase1 (PDK1), a master regulator that is essential throughout eukaryotic
growth and development, we employed a forward genetic approach to screen for suppressors
of the loss-of-function T-DNA insertion double mutant pdk1.1 pdk1.2 in Arabidopsis
thaliana. Notably, the severe growth attenuation of pdk1.1 pdk1.2 was rescued
by sop21 (suppressor of pdk1.1 pdk1.2), which harbours a loss-of-function mutation
in PELOTA1 (PEL1). PEL1 is a homologue of mammalian PELOTA and yeast (Saccharomyces
cerevisiae) DOM34p, which each form a heterodimeric complex with the GTPase HBS1
(HSP70 SUBFAMILY B SUPPRESSOR1, also called SUPERKILLER PROTEIN7, SKI7), a protein
that is responsible for ribosomal rescue and thereby assures the quality and fidelity
of mRNA molecules during translation. Genetic analysis further revealed that a
dysfunctional PEL1-HBS1 complex failed to degrade the T-DNA-disrupted PDK1 transcripts,
which were truncated but functional, and thus rescued the growth and developmental
defects of pdk1.1 pdk1.2. Our studies demonstrated the functionality of a homologous
PELOTA-HBS1 complex and identified its essential regulatory role in plants, providing
insights into the mechanism of mRNA quality control.

text: If there are no constraints on the process of speciation, then the number
of species might be expected to match the number of available niches and this
number might be indefinitely large. One possible constraint is the opportunity
for allopatric divergence. In 1981, Felsenstein used a simple and elegant model
to ask if there might also be genetic constraints. He showed that progress towards
speciation could be described by the build‐up of linkage disequilibrium among
divergently selected loci and between these loci and those contributing to other
forms of reproductive isolation. Therefore, speciation is opposed by recombination,
because it tends to break down linkage disequilibria. Felsenstein then introduced
a crucial distinction between “two‐allele” models, which are subject to this effect,
and “one‐allele” models, which are free from the recombination constraint. These
fundamentally important insights have been the foundation for both empirical and
theoretical studies of speciation ever since.
