text: We investigate how the critical driving amplitude at the Floquet many-body
localized (MBL) to ergodic phase transition differs between smooth and nonsmooth
drives. To this end, we numerically study a disordered spin-1/2 chain which is
periodically driven by a sine or square-wave drive over a wide range of driving
frequencies. In both cases the critical driving amplitude increases monotonically
with the frequency, and at large frequencies it is identical for the two drives.
However, at low and intermediate frequencies the critical amplitude of the square-wave
drive depends strongly on the frequency, while that of the sinusoidal drive is
almost constant over a wide frequency range. By analyzing the density of drive-induced
resonances we conclude that this difference is due to resonances induced by the
higher harmonics which are present (absent) in the Fourier spectrum of the square-wave
(sine) drive. Furthermore, we suggest a numerically efficient method for estimating
the frequency dependence of the critical driving amplitudes for different drives
which is based on calculating the density of drive-induced resonances. We conclude
that delocalization occurs once the density of drive-induced resonances reaches
a critical value determined only by the static system.

text: 'We consider the following setting: suppose that we are given a manifold M
in Rd with positive reach. Moreover assume that we have an embedded simplical
complex A without boundary, whose vertex set lies on the manifold, is sufficiently
dense and such that all simplices in A have sufficient quality. We prove that
if, locally, interiors of the projection of the simplices onto the tangent space
do not intersect, then A is a triangulation of the manifold, that is, they are

text: Brains process information in spiking neural networks. Their intricate connections
shape the diverse functions these networks perform. In comparison, the functional
capabilities of models of spiking networks are still rudimentary. This shortcoming
is mainly due to the lack of insight and practical algorithms to construct the
necessary connectivity. Any such algorithm typically attempts to build networks
by iteratively reducing the error compared to a desired output. But assigning
credit to hidden units in multi-layered spiking networks has remained challenging
due to the non-differentiable nonlinearity of spikes. To avoid this issue, one
can employ surrogate gradients to discover the required connectivity in spiking
network models. However, the choice of a surrogate is not unique, raising the
question of how its implementation influences the effectiveness of the method.
Here, we use numerical simulations to systematically study how essential design
parameters of surrogate gradients impact learning performance on a range of classification
problems. We show that surrogate gradient learning is robust to different shapes
of underlying surrogate derivatives, but the choice of the derivative’s scale
can substantially affect learning performance. When we combine surrogate gradients
with a suitable activity regularization technique, robust information processing
can be achieved in spiking networks even at the sparse activity limit. Our study
provides a systematic account of the remarkable robustness of surrogate gradient
learning and serves as a practical guide to model functional spiking neural networks.

text: "We consider the following dynamic load-balancing process: given an underlying
graph G with n nodes, in each step t≥ 0, one unit of load is created, and placed
at a randomly chosen graph node. In the same step, the chosen node picks a random
neighbor, and the two nodes balance their loads by averaging them. We are interested
in the expected gap between the minimum and maximum loads at nodes as the process
progresses, and its dependence on n and on the graph structure. Variants of the
above graphical balanced allocation process have been studied previously by Peres,
Talwar, and Wieder [Peres et al., 2015], and by Sauerwald and Sun [Sauerwald and
Sun, 2015]. These authors left as open the question of characterizing the gap
in the case of cycle graphs in the dynamic case, where weights are created during
the algorithm’s execution. For this case, the only known upper bound is of \U0001D4AA(n
log n), following from a majorization argument due to [Peres et al., 2015], which
analyzes a related graphical allocation process. In this paper, we provide an
upper bound of \U0001D4AA (√n log n) on the expected gap of the above process
for cycles of length n. We introduce a new potential analysis technique, which
enables us to bound the difference in load between k-hop neighbors on the cycle,
for any k ≤ n/2. We complement this with a \"gap covering\" argument, which bounds
the maximum value of the gap by bounding its value across all possible subsets
of a certain structure, and recursively bounding the gaps within each subset.
We provide analytical and experimental evidence that our upper bound on the gap
is tight up to a logarithmic factor. "

text: When can a polyomino piece of paper be folded into a unit cube? Prior work
studied tree-like polyominoes, but polyominoes with holes remain an intriguing
open problem. We present sufficient conditions for a polyomino with one or several
holes to fold into a cube, and conditions under which cube folding is impossible.
In particular, we show that all but five special “basic” holes guarantee foldability.

text: Canonical parametrisations of classical confocal coordinate systems are introduced
and exploited to construct non-planar analogues of incircular (IC) nets on individual
quadrics and systems of confocal quadrics. Intimate connections with classical
deformations of quadrics that are isometric along asymptotic lines and circular
cross-sections of quadrics are revealed. The existence of octahedral webs of surfaces
of Blaschke type generated by asymptotic and characteristic lines that are diagonally
related to lines of curvature is proved theoretically and established constructively.
Appropriate samplings (grids) of these webs lead to three-dimensional extensions
of non-planar IC nets. Three-dimensional octahedral grids composed of planes and
spatially extending (checkerboard) IC-nets are shown to arise in connection with
systems of confocal quadrics in Minkowski space. In this context, the Laguerre
geometric notion of conical octahedral grids of planes is introduced. The latter
generalise the octahedral grids derived from systems of confocal quadrics in Minkowski
space. An explicit construction of conical octahedral grids is presented. The
results are accompanied by various illustrations which are based on the explicit
formulae provided by the theory.

text: It is well known that special Kubo-Ando operator means admit divergence center
interpretations, moreover, they are also mean squared error estimators for certain
metrics on positive definite operators. In this paper we give a divergence center
interpretation for every symmetric Kubo-Ando mean. This characterization of the
symmetric means naturally leads to a definition of weighted and multivariate versions
of a large class of symmetric Kubo-Ando means. We study elementary properties
of these weighted multivariate means, and note in particular that in the special
case of the geometric mean we recover the weighted A#H-mean introduced by Kim,
Lawson, and Lim.

text: We develop a Bayesian model (BayesRR-RC) that provides robust SNP-heritability
estimation, an alternative to marker discovery, and accurate genomic prediction,
taking 22 seconds per iteration to estimate 8.4 million SNP-effects and 78 SNP-heritability
parameters in the UK Biobank. We find that only ≤10% of the genetic variation
captured for height, body mass index, cardiovascular disease, and type 2 diabetes
is attributable to proximal regulatory regions within 10kb upstream of genes,
while 12-25% is attributed to coding regions, 32–44% to introns, and 22-28% to
distal 10-500kb upstream regions. Up to 24% of all cis and coding regions of each
chromosome are associated with each trait, with over 3,100 independent exonic
and intronic regions and over 5,400 independent regulatory regions having ≥95%
probability of contributing ≥0.001% to the genetic variance of these four traits.
Our open-source software (GMRM) provides a scalable alternative to current approaches
for biobank data.

text: While recent advancements in computation and modelling have improved the analysis
of complex traits, our understanding of the genetic basis of the time at symptom
onset remains limited. Here, we develop a Bayesian approach (BayesW) that provides
probabilistic inference of the genetic architecture of age-at-onset phenotypes
in a sampling scheme that facilitates biobank-scale time-to-event analyses. We
show in extensive simulation work the benefits BayesW provides in terms of number
of discoveries, model performance and genomic prediction. In the UK Biobank, we
find many thousands of common genomic regions underlying the age-at-onset of high
blood pressure (HBP), cardiac disease (CAD), and type-2 diabetes (T2D), and for
the genetic basis of onset reflecting the underlying genetic liability to disease.
Age-at-menopause and age-at-menarche are also highly polygenic, but with higher
variance contributed by low frequency variants. Genomic prediction into the Estonian
Biobank data shows that BayesW gives higher prediction accuracy than other approaches.

text: The synaptotrophic hypothesis posits that synapse formation stabilizes dendritic
branches, yet this hypothesis has not been causally tested in vivo in the mammalian
brain. Presynaptic ligand cerebellin-1 (Cbln1) and postsynaptic receptor GluD2
mediate synaptogenesis between granule cells and Purkinje cells in the molecular
layer of the cerebellar cortex. Here we show that sparse but not global knockout
of GluD2 causes under-elaboration of Purkinje cell dendrites in the deep molecular
layer and overelaboration in the superficial molecular layer. Developmental, overexpression,
structure-function, and genetic epistasis analyses indicate that dendrite morphogenesis
defects result from competitive synaptogenesis in a Cbln1/GluD2-dependent manner.
A generative model of dendritic growth based on competitive synaptogenesis largely
recapitulates GluD2 sparse and global knockout phenotypes. Our results support
the synaptotrophic hypothesis at initial stages of dendrite development, suggest
a second mode in which cumulative synapse formation inhibits further dendrite
growth, and highlight the importance of competition in dendrite morphogenesis.

text: Brain neurons arise from relatively few progenitors generating an enormous
diversity of neuronal types. Nonetheless, a cardinal feature of mammalian brain
neurogenesis is thought to be that excitatory and inhibitory neurons derive from
separate, spatially segregated progenitors. Whether bi-potential progenitors with
an intrinsic capacity to generate both lineages exist and how such a fate decision
may be regulated are unknown. Using cerebellar development as a model, we discover
that individual progenitors can give rise to both inhibitory and excitatory lineages.
Gradations of Notch activity determine the fates of the progenitors and their
daughters. Daughters with the highest levels of Notch activity retain the progenitor
fate, while intermediate levels of Notch activity generate inhibitory neurons,
and daughters with very low levels of Notch signaling adopt the excitatory fate.
Therefore, Notch-mediated binary cell fate choice is a mechanism for regulating
the ratio of excitatory to inhibitory neurons from common progenitors.

text: "Cell and tissue polarization is fundamental for plant growth and morphogenesis.
The polar, cellular localization of Arabidopsis PIN‐FORMED (PIN) proteins is crucial
for their function in directional auxin transport. The clustering of PIN polar
cargoes within the plasma membrane has been proposed to be important for the maintenance
of their polar distribution. However, the more detailed features of PIN clusters
and the cellular requirements of cargo clustering remain unclear.\r\nHere, we
characterized PIN clusters in detail by means of multiple advanced microscopy
and quantification methods, such as 3D quantitative imaging or freeze‐fracture
replica labeling. The size and aggregation types of PIN clusters were determined
by electron microscopy at the nanometer level at different polar domains and at
different developmental stages, revealing a strong preference for clustering at
the polar domains.\r\nPharmacological and genetic studies revealed that PIN clusters
depend on phosphoinositol pathways, cytoskeletal structures and specific cell‐wall
components as well as connections between the cell wall and the plasma membrane.\r\nThis
study identifies the role of different cellular processes and structures in polar
cargo clustering and provides initial mechanistic insight into the maintenance
of polarity in plants and other systems."

text: We consider large non-Hermitian real or complex random matrices X with independent,
identically distributed centred entries. We prove that their local eigenvalue
statistics near the spectral edge, the unit circle, coincide with those of the
Ginibre ensemble, i.e. when the matrix elements of X are Gaussian. This result
is the non-Hermitian counterpart of the universality of the Tracy–Widom distribution
at the spectral edges of the Wigner ensemble.

text: Collective cell migration offers a rich field of study for non-equilibrium
physics and cellular biology, revealing phenomena such as glassy dynamics, pattern
formation and active turbulence. However, how mechanical and chemical signalling
are integrated at the cellular level to give rise to such collective behaviours
remains unclear. We address this by focusing on the highly conserved phenomenon
of spatiotemporal waves of density and extracellular signal-regulated kinase (ERK)
activation, which appear both in vitro and in vivo during collective cell migration
and wound healing. First, we propose a biophysical theory, backed by mechanical
and optogenetic perturbation experiments, showing that patterns can be quantitatively
explained by a mechanochemical coupling between active cellular tensions and the
mechanosensitive ERK pathway. Next, we demonstrate how this biophysical mechanism
can robustly induce long-ranged order and migration in a desired orientation,
and we determine the theoretically optimal wavelength and period for inducing
maximal migration towards free edges, which fits well with experimentally observed
dynamics. We thereby provide a bridge between the biophysical origin of spatiotemporal
instabilities and the design principles of robust and efficient long-ranged migration.

text: We consider the Fröhlich polaron model in the strong coupling limit. It is
well‐known that to leading order the ground state energy is given by the (classical)
Pekar energy. In this work, we establish the subleading correction, describing
quantum fluctuation about the classical limit. Our proof applies to a model of
a confined polaron, where both the electron and the polarization field are restricted
to a set of finite volume, with linear size determined by the natural length scale
of the Pekar problem.

text: The leaf is a crucial organ evolved with remarkable morphological diversity
to maximize plant photosynthesis. The leaf shape is a key trait that affects photosynthesis,
flowering rates, disease resistance, and yield. Although many genes regulating
leaf development have been identified in the past years, the precise regulatory
architecture underlying the generation of diverse leaf shapes remains to be elucidated.
We used cotton as a reference model to probe the genetic framework underlying
divergent leaf forms. Comparative transcriptome analysis revealed that the GhARF16‐1
and GhKNOX2‐1 genes might be potential regulators of leaf shape. We functionally
characterized the auxin‐responsive factor ARF16‐1 acting upstream of GhKNOX2‐1
to determine leaf morphology in cotton. The transcription of GhARF16‐1 was significantly
higher in lobed‐leaved cotton than in smooth‐leaved cotton. Furthermore, the overexpression
of GhARF16‐1 led to the upregulation of GhKNOX2‐1 and resulted in more and deeper
serrations in cotton leaves, similar to the leaf shape of cotton plants overexpressing
GhKNOX2‐1. We found that GhARF16‐1 specifically bound to the promoter of GhKNOX2‐1
to induce its expression. The heterologous expression of GhARF16‐1 and GhKNOX2‐1
in Arabidopsis led to lobed and curly leaves, and a genetic analysis revealed
that GhKNOX2‐1 is epistatic to GhARF16‐1 in Arabidopsis, suggesting that the GhARF16‐1
and GhKNOX2‐1 interaction paradigm also functions to regulate leaf shape in Arabidopsis.
To our knowledge, our results uncover a novel mechanism by which auxin, through
the key component ARF16‐1 and its downstream‐activated gene KNOX2‐1, determines
leaf morphology in eudicots.

text: To adapt to the diverse array of biotic and abiotic cues, plants have evolved
sophisticated mechanisms to sense changes in environmental conditions and modulate
their growth. Growth-promoting hormones and defence signalling fine tune plant
development antagonistically. During host-pathogen interactions, this defence-growth
trade-off is mediated by the counteractive effects of the defence hormone salicylic
acid (SA) and the growth hormone auxin. Here we revealed an underlying mechanism
of SA regulating auxin signalling by constraining the plasma membrane dynamics
of PIN2 auxin efflux transporter in Arabidopsis thaliana roots. The lateral diffusion
of PIN2 proteins is constrained by SA signalling, during which PIN2 proteins are
condensed into hyperclusters depending on REM1.2-mediated nanodomain compartmentalisation.
Furthermore, membrane nanodomain compartmentalisation by SA or Remorin (REM) assembly
significantly suppressed clathrin-mediated endocytosis. Consequently, SA-induced
heterogeneous surface condensation disrupted asymmetric auxin distribution and
the resultant gravitropic response. Our results demonstrated a defence-growth
trade-off mechanism by which SA signalling crosstalked with auxin transport by
concentrating membrane-resident PIN2 into heterogeneous compartments.

text: In RuCl3, inelastic neutron scattering and Raman spectroscopy reveal a continuum
of non-spin-wave excitations that persists to high temperature, suggesting the
presence of a spin liquid state on a honeycomb lattice. In the context of the
Kitaev model, finite magnetic fields introduce interactions between the elementary
excitations, and thus the effects of high magnetic fields that are comparable
to the spin-exchange energy scale must be explored. Here, we report measurements
of the magnetotropic coefficient—the thermodynamic coefficient associated with
magnetic anisotropy—over a wide range of magnetic fields and temperatures. We
find that magnetic field and temperature compete to determine the magnetic response
in a way that is independent of the large intrinsic exchange-interaction energy.
This emergent scale-invariant magnetic anisotropy provides evidence for a high
degree of exchange frustration that favours the formation of a spin liquid state
in RuCl3.

text: 'This paper continues the discussion started in [CK19] concerning Arnold''s
legacy on classical KAM theory and (some of) its modern developments. We prove
a detailed and explicit `global'' Arnold''s KAM Theorem, which yields, in particular,
the Whitney conjugacy of a non{degenerate, real{analytic, nearly-integrable Hamiltonian
system to an integrable system on a closed, nowhere dense, positive measure subset
of the phase space. Detailed measure estimates on the Kolmogorov''s set are provided
in the case the phase space is: (A) a uniform neighbourhood of an arbitrary (bounded)
set times the d-torus and (B) a domain with C2 boundary times the d-torus. All
constants are explicitly given.'

text: The Mytilus complex of marine mussel species forms a mosaic of hybrid zones,
found across temperate regions of the globe. This allows us to study ‘replicated’
instances of secondary contact between closely related species. Previous work
on this complex has shown that local introgression is both widespread and highly
heterogeneous, and has identified SNPs that are outliers of differentiation between
lineages. Here, we developed an ancestry‐informative panel of such SNPs. We then
compared their frequencies in newly sampled populations, including samples from
within the hybrid zones, and parental populations at different distances from
the contact. Results show that close to the hybrid zones, some outlier loci are
near to fixation for the heterospecific allele, suggesting enhanced local introgression,
or the local sweep of a shared ancestral allele. Conversely, genomic cline analyses,
treating local parental populations as the reference, reveal a globally high concordance
among loci, albeit with a few signals of asymmetric introgression. Enhanced local
introgression at specific loci is consistent with the early transfer of adaptive
variants after contact, possibly including asymmetric bi‐stable variants (Dobzhansky‐Muller
incompatibilities), or haplotypes loaded with fewer deleterious mutations. Having
escaped one barrier, however, these variants can be trapped or delayed at the
next barrier, confining the introgression locally. These results shed light on
the decay of species barriers during phases of contact.
