text: Autocrine signaling pathways regulated by RAPID ALKALINIZATION FACTORs (RALFs)
control cell wall integrity during pollen tube germination and growth in Arabidopsis
(Arabidopsis thaliana). To investigate the role of pollen-specific RALFs in another
plant species, we combined gene expression data with phylogenetic and biochemical
studies to identify candidate orthologs in maize (Zea mays). We show that Clade
IB ZmRALF2/3 mutations, but not Clade III ZmRALF1/5 mutations, cause cell wall
instability in the sub-apical region of the growing pollen tube. ZmRALF2/3 are
mainly located in the cell wall and are partially able to complement the pollen
germination defect of their Arabidopsis orthologs AtRALF4/19. Mutations in ZmRALF2/3
compromise pectin distribution patterns leading to altered cell wall organization
and thickness culminating in pollen tube burst. Clade IB, but not Clade III ZmRALFs,
strongly interact as ligands with the pollen-specific Catharanthus roseus RLK1-like
(CrRLK1L) receptor kinases Zea mays FERONIA-like (ZmFERL) 4/7/9, LORELEI-like
glycosylphosphatidylinositol-anchor (LLG) proteins Zea mays LLG 1 and 2 (ZmLLG1/2)
and Zea mays pollen extension-like (PEX) cell wall proteins ZmPEX2/4. Notably,
ZmFERL4 outcompetes ZmLLG2 and ZmPEX2 outcompetes ZmFERL4 for ZmRALF2 binding.
Based on these data, we suggest that Clade IB RALFs act in a dual role as cell
wall components and extracellular sensors to regulate cell wall integrity and
thickness during pollen tube growth in maize and probably other plants.

text: 'Fragmented landscapes pose a significant threat to the persistence of species
as they are highly susceptible to heightened risk of extinction due to the combined
effects of genetic and demographic factors such as genetic drift and demographic
stochasticity. This paper explores the intricate interplay between genetic load
and extinction risk within metapopulations with a focus on understanding the impact
of eco-evolutionary feedback mechanisms. We distinguish between two models of
selection: soft selection, characterised by subpopulations maintaining carrying
capacity despite load, and hard selection, where load can significantly affect
population size. Within the soft selection framework, we investigate the impact
of gene flow on genetic load at a single locus, while also considering the effect
of selection strength and dominance coefficient. We subsequently build on this
to examine how gene flow influences both population size and load under hard selection
as well as identify critical thresholds for metapopulation persistence. Our analysis
employs the diffusion, semi-deterministic and effective migration approximations.
Our findings reveal that under soft selection, even modest levels of migration
can significantly alleviate the burden of load. In sharp contrast, with hard selection,
a much higher degree of gene flow is required to mitigate load and prevent the
collapse of the metapopulation. Overall, this study sheds light into the crucial
role migration plays in shaping the dynamics of genetic load and extinction risk
in fragmented landscapes, offering valuable insights for conservation strategies
and the preservation of diversity in a changing world.'

text: Redox flow batteries (RFBs) rely on the development of cheap, highly soluble,
and high-energy-density electrolytes. Several candidate quinones have already
been investigated in the literature as two-electron anolytes or catholytes, benefiting
from fast kinetics, high tunability, and low cost. Here, an investigation of nitrogen-rich
fused heteroaromatic quinones was carried out to explore avenues for electrolyte
development. These quinones were synthesized and screened by using electrochemical
techniques. The most promising candidate, 4,8-dioxo-4,8-dihydrobenzo[1,2-d:4,5-d′]bis([1,2,3]triazole)-1,5-diide
(−0.68 V(SHE)), was tested in both an asymmetric and symmetric full-cell setup
resulting in capacity fade rates of 0.35% per cycle and 0.0124% per cycle, respectively.
In situ ultraviolet-visible spectroscopy (UV–Vis), nuclear magnetic resonance
(NMR), and electron paramagnetic resonance (EPR) spectroscopies were used to investigate
the electrochemical stability of the charged species during operation. UV–Vis
spectroscopy, supported by density functional theory (DFT) modeling, reaffirmed
that the two-step charging mechanism observed during battery operation consisted
of two, single-electron transfers. The radical concentration during battery operation
and the degree of delocalization of the unpaired electron were quantified with
NMR and EPR spectroscopy.

text: "Scaling blockchain protocols to perform on par with the expected needs of
Web3.0 has been proven to be a challenging task with almost a decade of research.
In the forefront of the current solution is the idea of separating the execution
of the updates encoded in a block from the ordering of blocks. In order to achieve
this, a new class of protocols called rollups has emerged. Rollups have as input
a total ordering of valid and invalid transactions and as output a new valid state-transition.\r\nIf
we study rollups from a distributed computing perspective, we uncover that rollups
take as input the output of a Byzantine Atomic Broadcast (BAB) protocol and convert
it to a State Machine Replication (SMR) protocol. BAB and SMR, however, are considered
equivalent as far as distributed computing is concerned and a solution to one
can easily be retrofitted to solve the other simply by adding/removing an execution
step before the validation of the input.\r\nThis “easy” step of retrofitting an
atomic broadcast solution to implement an SMR has, however, been overlooked in
practice. In this paper, we formalize the problem and show that after BAB is solved,
traditional impossibility results for consensus no longer apply towards an SMR.
Leveraging this we propose a distributed execution protocol that allows reduced
execution and storage cost per executor (O(log2n/n)) without relaxing the network
assumptions of the underlying BAB protocol and providing censorship-resistance.
Finally, we propose efficient non-interactive light client constructions that
leverage our efficient execution protocols and do not require any synchrony assumptions
or expensive ZK-proofs."

text: 'John’s fundamental theorem characterizing the largest volume ellipsoid contained
in a convex body $K$ in $\mathbb{R}^{d}$ has seen several generalizations and
extensions. One direction, initiated by V. Milman is to replace ellipsoids by
positions (affine images) of another body $L$. Another, more recent direction
is to consider logarithmically concave functions on $\mathbb{R}^{d}$ instead of
convex bodies: we designate some special, radially symmetric log-concave function
$g$ as the analogue of the Euclidean ball, and want to find its largest integral
position under the constraint that it is pointwise below some given log-concave
function $f$. We follow both directions simultaneously: we consider the functional
question, and allow essentially any meaningful function to play the role of $g$
above. Our general theorems jointly extend known results in both directions. The
dual problem in the setting of convex bodies asks for the smallest volume ellipsoid,
called Löwner’s ellipsoid, containing $K$. We consider the analogous problem for
functions: we characterize the solutions of the optimization problem of finding
a smallest integral position of some log-concave function $g$ under the constraint
that it is pointwise above $f$. It turns out that in the functional setting, the
relationship between the John and the Löwner problems is more intricate than it
is in the setting of convex bodies.'

text: Attempts to incorporate topological information in supervised learning tasks
have resulted in the creation of several techniques for vectorizing persistent
homology barcodes. In this paper, we study thirteen such methods. Besides describing
an organizational framework for these methods, we comprehensively benchmark them
against three well-known classification tasks. Surprisingly, we discover that
the best-performing method is a simple vectorization, which consists only of a
few elementary summary statistics. Finally, we provide a convenient web application
which has been designed to facilitate exploration and experimentation with various
vectorization methods.

text: "Chromosomal rearrangements (CRs) have been known since almost the beginning
of genetics.\r\nWhile an important role for CRs in speciation has been suggested,
evidence primarily stems\r\nfrom theoretical and empirical studies focusing on
the microevolutionary level (i.e., on taxon\r\npairs where speciation is often
incomplete). Although the role of CRs in eukaryotic speciation at\r\na macroevolutionary
level has been supported by associations between species diversity and\r\nrates
of evolution of CRs across phylogenies, these findings are limited to a restricted
range of\r\nCRs and taxa. Now that more broadly applicable and precise CR detection
approaches have\r\nbecome available, we address the challenges in filling some
of the conceptual and empirical\r\ngaps between micro- and macroevolutionary studies
on the role of CRs in speciation. We\r\nsynthesize what is known about the macroevolutionary
impact of CRs and suggest new research avenues to overcome the pitfalls of previous
studies to gain a more comprehensive understanding of the evolutionary significance
of CRs in speciation across the tree of life."

text: Leader-based consensus algorithms are fast and efficient under normal conditions,
but lack robustness to adverse conditions due to their reliance on timeouts for
liveness. We present QuePaxa, the first protocol offering state-of-the-art normal-case
efficiency without depending on timeouts. QuePaxa uses a novel randomized asynchronous
consensus core to tolerate adverse conditions such as denial-of-service (DoS)
attacks, while a one-round-trip fast path preserves the normal-case efficiency
of Multi-Paxos or Raft. By allowing simultaneous proposers without destructive
interference, and using short hedging delays instead of conservative timeouts
to limit redundant effort, QuePaxa permits rapid recovery after leader failure
without risking costly view changes due to false timeouts. By treating leader
choice and hedging delay as a multi-armed-bandit optimization, QuePaxa achieves
responsiveness to prevalent conditions, and can choose the best leader even if
the current one has not failed. Experiments with a prototype confirm that QuePaxa
achieves normal-case LAN and WAN performance of 584k and 250k cmd/sec in throughput,
respectively, comparable to Multi-Paxos. Under conditions such as DoS attacks,
misconfigurations, or slow leaders that severely impact existing protocols, we
find that QuePaxa remains live with median latency under 380ms in WAN experiments.

text: "Consider the random matrix model A1/2UBU∗A1/2, where A and B are two N ×
N deterministic matrices and U is either an N × N Haar unitary or orthogonal random
matrix. It is well known that on the macroscopic scale (Invent. Math. 104 (1991)
201–220), the limiting empirical spectral distribution (ESD) of the above model
is given by the free multiplicative convolution\r\nof the limiting ESDs of A and
B, denoted as μα \x02 μβ, where μα and μβ are the limiting ESDs of A and B, respectively.
In this paper, we study the asymptotic microscopic behavior of the edge eigenvalues
and eigenvectors statistics. We prove that both the density of μA \x02μB, where
μA and μB are the ESDs of A and B, respectively and the associated subordination
functions\r\nhave a regular behavior near the edges. Moreover, we establish the
local laws near the edges on the optimal scale. In particular, we prove that the
entries of the resolvent are close to some functionals depending only on the eigenvalues
of A, B and the subordination functions with optimal convergence rates. Our proofs
and calculations are based on the techniques developed for the additive model
A+UBU∗ in (J. Funct. Anal. 271 (2016) 672–719; Comm. Math.\r\nPhys. 349 (2017)
947–990; Adv. Math. 319 (2017) 251–291; J. Funct. Anal. 279 (2020) 108639), and
our results can be regarded as the counterparts of (J. Funct. Anal. 279 (2020)
108639) for the multiplicative model. "

text: 'We consider zero-error communication over a two-transmitter deterministic
adversarial multiple access channel (MAC) governed by an adversary who has access
to the transmissions of both senders (hence called omniscient ) and aims to maliciously
corrupt the communication. None of the encoders, jammer and decoder is allowed
to randomize using private or public randomness. This enforces a combinatorial
nature of the problem. Our model covers a large family of channels studied in
the literature, including all deterministic discrete memoryless noisy or noiseless
MACs. In this work, given an arbitrary two-transmitter deterministic omniscient
adversarial MAC, we characterize when the capacity region: 1) has nonempty interior
(in particular, is two-dimensional); 2) consists of two line segments (in particular,
has empty interior); 3) consists of one line segment (in particular, is one-dimensional);
4) or only contains (0,0) (in particular, is zero-dimensional). This extends a
recent result by Wang et al. (201 9) from the point-to-point setting to the multiple
access setting. Indeed, our converse arguments build upon their generalized Plotkin
bound and involve delicate case analysis. One of the technical challenges is to
take care of both “joint confusability” and “marginal confusability”. In particular,
the treatment of marginal confusability does not follow from the point-to-point
results by Wang et al. Our achievability results follow from random coding with
expurgation.'

text: 'Radiative cooling of the lowest atmospheric levels is of strong importance
for modulating atmospheric circulations and organizing convection, but detailed
observations and a robust theoretical understanding are lacking. Here we use unprecedented
observational constraints from subsidence regimes in the tropical Atlantic to
develop a theory for the shape and magnitude of low‐level longwave radiative cooling
in clear‐sky, showing peaks larger than 5–10 K/day at the top of the boundary
layer. A suite of novel scaling approximations is first developed from simplified
spectral theory, in close agreement with the measurements. The radiative cooling
peak height is set by the maximum lapse rate in water vapor path, and its magnitude
is mainly controlled by the ratio of column relative humidity above and below
the peak. We emphasize how elevated intrusions of moist air can reduce low‐level
cooling, by sporadically shading the spectral range which effectively cools to
space. The efficiency of this spectral shading depends both on water content and
altitude of moist intrusions; its height dependence cannot be explained by the
temperature difference between the emitting and absorbing layers, but by the decrease
of water vapor extinction with altitude. This analytical work can help to narrow
the search for low‐level cloud patterns sensitive to radiative‐convective feedbacks:
the most organized patterns with largest cloud fractions occur in atmospheres
below 10% relative humidity and feel the strongest low‐level cooling. This motivates
further assessment of favorable conditions for radiative‐convective feedbacks
and a robust quantification of corresponding shallow cloud dynamics in current
and warmer climates.'

text: "Several fixed-target experiments reported J/ψ and ϒ polarizations, as functions
of Feynman x (xF) and transverse momentum (PT), in three different frames, using
different combinations of beam particles, target nuclei, and collision energies.
Despite the diverse and heterogeneous picture formed by these measurements, a
detailed look allows us to discern qualitative physical patterns that inspire
a simple empirical model. This data-driven scenario offers a good quantitative
description of the J/ψ and ϒ(1S) polarizations measured in proton- and pion-nucleus
collisions, in the xF 0.5 domain: more than 80 data points (not statistically
independent) are well reproduced with only one free parameter. This study sets
the context for future low-PT\r\n quarkonium polarization measurements in proton-
and pion-nucleus collisions, such as those to be made by the AMBER experiment,
and shows that such measurements provide significant constraints on the poorly-known
parton distribution functions of the pion."

text: The large-scale laminar/turbulent spiral patterns that appear in the linearly
unstable regime of counter-rotating Taylor–Couette flow are investigated from
a statistical perspective by means of direct numerical simulation. Unlike the
vast majority of previous numerical studies, we analyse the flow in periodic parallelogram-annular
domains, following a coordinate change that aligns one of the parallelogram sides
with the spiral pattern. The domain size, shape and spatial resolution have been
varied and the results compared with those in a sufficiently large computational
orthogonal domain with natural axial and azimuthal periodicity. We find that a
minimal parallelogram of the right tilt significantly reduces the computational
cost without notably compromising the statistical properties of the supercritical
turbulent spiral. Its mean structure, obtained from extremely long time integrations
in a co-rotating reference frame using the method of slices, bears remarkable
similarity with the turbulent stripes observed in plane Couette flow, the centrifugal
instability playing only a secondary role.

text: We consider the sharp interface limit for the scalar-valued and vector-valued
Allen–Cahn equation with homogeneous Neumann boundary condition in a bounded smooth
domain Ω of arbitrary dimension N ⩾ 2 in the situation when a two-phase diffuse
interface has developed and intersects the boundary ∂ Ω. The limit problem is
mean curvature flow with 90°-contact angle and we show convergence in strong norms
for well-prepared initial data as long as a smooth solution to the limit problem
exists. To this end we assume that the limit problem has a smooth solution on
[ 0 , T ] for some time T > 0. Based on the latter we construct suitable curvilinear
coordinates and set up an asymptotic expansion for the scalar-valued and the vector-valued
Allen–Cahn equation. In order to estimate the difference of the exact and approximate
solutions with a Gronwall-type argument, a spectral estimate for the linearized
Allen–Cahn operator in both cases is required. The latter will be shown in a separate
paper, cf. (Moser (2021)).

text: "We prove the r-spin cobordism hypothesis in the setting of (weak) 2-categories
for every positive integer r: the 2-groupoid of 2-dimensional fully extended r-spin
TQFTs with given target is equivalent to the homotopy fixed points of an induced
Spin 2r -action. In particular, such TQFTs are classified by fully dualisable
objects together with a trivialisation of the rth power of their Serre automorphisms.
For r=1, we recover the oriented case (on which our proof builds), while ordinary
spin structures correspond to r=2.\r\nTo construct examples, we explicitly describe
Spin 2r-homotopy fixed points in the equivariant completion of any symmetric
monoidal 2-category. We also show that every object in a 2-category of Landau–Ginzburg
models gives rise to fully extended spin TQFTs and that half of these do not factor
through the oriented bordism 2-category."

text: 'We present a flexible and efficient toolchain to symbolically solve (standard)
Rabin games, fair-adversarial Rabin games, and 2 1/2 license type-player Rabin
games. To our best knowledge, our tools are the first ones to be able to solve
these problems. Furthermore, using these flexible game solvers as a back-end,
we implemented a tool for computing correct-by-construction controllers for stochastic
dynamical systems under LTL specifications. Our implementations use the recent
theoretical result that all of these games can be solved using the same symbolic
fixpoint algorithm but utilizing different, domain specific calculations of the
involved predecessor operators. The main feature of our toolchain is the utilization
of two programming abstractions: one to separate the symbolic fixpoint computations
from the predecessor calculations, and another one to allow the integration of
different BDD libraries as back-ends. In particular, we employ a multi-threaded
execution of the fixpoint algorithm by using the multi-threaded BDD library Sylvan,
which leads to enormous computational savings.'

text: "Proper operation of electro-optic I/Q modulators relies on precise adjustment
and control of the relative phase biases between the modulator’s internal interferometer
arms. We present an all-analog phase bias locking scheme where error signals are
obtained from the beat between the optical carrier and optical tones generated
by an auxiliary 2 MHz \U0001D445\U0001D439 tone to lock the phases of all three
involved interferometers for operation up to 10 GHz. With the developed method,
we demonstrate an I/Q modulator in carrier-suppressed single-sideband mode, where
the suppressed carrier and sideband are locked at optical power levels <−27dB\r\n
relative to the transmitted sideband. We describe a simple analytical model for
calculating the error signals and detail the implementation of the electronic
circuitry for the implementation of the method."

text: 'In all state-of-the-art sketching and coreset techniques for clustering,
as well as in the best known fixed-parameter tractable approximation algorithms,
randomness plays a key role. For the classic k-median and k-means problems, there
are no known deterministic dimensionality reduction procedure or coreset construction
that avoid an exponential dependency on the input dimension d, the precision parameter
$\varepsilon^{-1}$ or k. Furthermore, there is no coreset construction that succeeds
with probability $1-1/n$ and whose size does not depend on the number of input
points, n. This has led researchers in the area to ask what is the power of randomness
for clustering sketches [Feldman WIREs Data Mining Knowl. Discov’20].Similarly,
the best approximation ratio achievable deterministically without a complexity
exponential in the dimension are $1+\sqrt{2}$ for k-median [Cohen-Addad, Esfandiari,
Mirrokni, Narayanan, STOC’22] and 6.12903 for k-means [Grandoni, Ostrovsky, Rabani,
Schulman, Venkat, Inf. Process. Lett.’22]. Those are the best results, even when
allowing a complexity FPT in the number of clusters k: this stands in sharp contrast
with the $(1+\varepsilon)$-approximation achievable in that case, when allowing
randomization.In this paper, we provide deterministic sketches constructions for
clustering, whose size bounds are close to the best-known randomized ones. We
show how to compute a dimension reduction onto $\varepsilon^{-O(1)} \log k$ dimensions
in time $k^{O\left(\varepsilon^{-O(1)}+\log \log k\right)}$ poly $(n d)$, and
how to build a coreset of size $O\left(k^{2} \log ^{3} k \varepsilon^{-O(1)}\right)$
in time $2^{\varepsilon^{O(1)} k \log ^{3} k}+k^{O\left(\varepsilon^{-O(1)}+\log
\log k\right)}$ poly $(n d)$. In the case where k is small, this answers an open
question of [Feldman WIDM’20] and [Munteanu and Schwiegelshohn, Künstliche Intell.
’18] on whether it is possible to efficiently compute coresets deterministically.We
also construct a deterministic algorithm for computing $(1+$ $\varepsilon)$-approximation
to k-median and k-means in high dimensional Euclidean spaces in time $2^{k^{2}
\log ^{3} k / \varepsilon^{O(1)}}$ poly $(n d)$, close to the best randomized
complexity of $2^{(k / \varepsilon)^{O(1)}}$ nd (see [Kumar, Sabharwal, Sen, JACM
10] and [Bhattacharya, Jaiswal, Kumar, TCS’18]).Furthermore, our new insights
on sketches also yield a randomized coreset construction that uses uniform sampling,
that immediately improves over the recent results of [Braverman et al. FOCS ’22]
by a factor k.'

text: Pruning—that is, setting a significant subset of the parameters of a neural
network to zero—is one of the most popular methods of model compression. Yet,
several recent works have raised the issue that pruning may induce or exacerbate
bias in the output of the compressed model. Despite existing evidence for this
phenomenon, the relationship between neural network pruning and induced bias is
not well-understood. In this work, we systematically investigate and characterize
this phenomenon in Convolutional Neural Networks for computer vision. First, we
show that it is in fact possible to obtain highly-sparse models, e.g. with less
than 10% remaining weights, which do not decrease in accuracy nor substantially
increase in bias when compared to dense models. At the same time, we also find
that, at higher sparsities, pruned models exhibit higher uncertainty in their
outputs, as well as increased correlations, which we directly link to increased
bias. We propose easy-to-use criteria which, based only on the uncompressed model,
establish whether bias will increase with pruning, and identify the samples most
susceptible to biased predictions post-compression. Our code can be found at https://github.com/IST-DASLab/pruned-vision-model-bias.

text: "Many coupled evolution equations can be described via 2×2-block operator
matrices of the form A=[ \r\nA\tB\r\nC\tD\r\n ] in a product space X=X1×X2 with
possibly unbounded entries. Here, the case of diagonally dominant block operator
matrices is considered, that is, the case where the full operator A can be seen
as a relatively bounded perturbation of its diagonal part with D(A)=D(A)×D(D)
though with possibly large relative bound. For such operators the properties of
sectoriality, R-sectoriality and the boundedness of the H∞-calculus are studied,
and for these properties perturbation results for possibly large but structured
perturbations are derived. Thereby, the time dependent parabolic problem associated
with A can be analyzed in maximal Lpt\r\n-regularity spaces, and this is applied
to a wide range of problems such as different theories for liquid crystals, an
artificial Stokes system, strongly damped wave and plate equations, and a Keller-Segel
model."
