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."

text: Morphogen gradients impart positional information to cells in a homogenous
tissue field. Fgf8a, a highly conserved growth factor, has been proposed to act
as a morphogen during zebrafish gastrulation. However, technical limitations have
so far prevented direct visualization of the endogenous Fgf8a gradient and confirmation
of its morphogenic activity. Here, we monitor Fgf8a propagation in the developing
neural plate using a CRISPR/Cas9-mediated EGFP knock-in at the endogenous fgf8a
locus. By combining sensitive imaging with single-molecule fluorescence correlation
spectroscopy, we demonstrate that Fgf8a, which is produced at the embryonic margin,
propagates by diffusion through the extracellular space and forms a graded distribution
towards the animal pole. Overlaying the Fgf8a gradient curve with expression profiles
of its downstream targets determines the precise input-output relationship of
Fgf8a-mediated patterning. Manipulation of the extracellular Fgf8a levels alters
the signaling outcome, thus establishing Fgf8a as a bona fide morphogen during
zebrafish gastrulation. Furthermore, by hindering Fgf8a diffusion, we demonstrate
that extracellular diffusion of the protein from the source is crucial for it
to achieve its morphogenic potential.

text: We establish a quantitative version of the Tracy–Widom law for the largest
eigenvalue of high-dimensional sample covariance matrices. To be precise, we show
that the fluctuations of the largest eigenvalue of a sample covariance matrix
X∗X converge to its Tracy–Widom limit at a rate nearly N−1/3, where X is an M×N
random matrix whose entries are independent real or complex random variables,
assuming that both M and N tend to infinity at a constant rate. This result improves
the previous estimate N−2/9 obtained by Wang (2019). Our proof relies on a Green
function comparison method (Adv. Math. 229 (2012) 1435–1515) using iterative cumulant
expansions, the local laws for the Green function and asymptotic properties of
the correlation kernel of the white Wishart ensemble.

text: Soluble chaperones residing in the endoplasmic reticulum (ER) play vitally
important roles in folding and quality control of newly synthesized proteins that
transiently pass through the ER en route to their final destinations. These soluble
residents of the ER are themselves endowed with an ER retrieval signal that enables
the cell to bring the escaped residents back from the Golgi. Here, by using purified
proteins, we showed that Nicotiana tabacum phytaspase, a plant aspartate-specific
protease, introduces two breaks at the C-terminus of the N. tabacum ER resident
calreticulin-3. These cleavages resulted in removal of either a dipeptide or a
hexapeptide from the C-terminus of calreticulin-3 encompassing part or all of
the ER retrieval signal. Consistently, expression of the calreticulin-3 derivative
mimicking the phytaspase cleavage product in Nicotiana benthamiana cells demonstrated
loss of the ER accumulation of the protein. Notably, upon its escape from the
ER, calreticulin-3 was further processed by an unknown protease(s) to generate
the free N-terminal (N) domain of calreticulin-3, which was ultimately secreted
into the apoplast. Our study thus identified a specific proteolytic enzyme capable
of precise detachment of the ER retrieval signal from a plant ER resident protein,
with implications for the further fate of the escaped resident.

text: The effects of the partial V-substitution for Ag on the thermoelectric (TE)
properties are investigated for a flexible semiconducting compound Ag2S0.55Se0.45.
Density functional theory calculations predict that such a partial V-substitution
constructively modifies the electronic structure near the bottom of the conduction
band to improve the TE performance. The synthesized Ag1.97V0.03S0.55Se0.45 is
found to possess a TE dimensionless figure-of-merit (ZT) of 0.71 at 350 K with
maintaining its flexible nature. This ZT value is relatively high in comparison
with those reported for flexible TE materials below 360 K. The increase in the
ZT value is caused by the enhanced absolute value of the Seebeck coefficient with
less significant variation in electrical resistivity. The high ZT value with the
flexible nature naturally allows us to employ the Ag1.97V0.03S0.55Se0.45 as a
component of flexible TE generators.

text: 'We consider the almost-sure (a.s.) termination problem for probabilistic
programs, which are a stochastic extension of classical imperative programs. Lexicographic
ranking functions provide a sound and practical approach for termination of non-probabilistic
programs, and their extension to probabilistic programs is achieved via lexicographic
ranking supermartingales (LexRSMs). However, LexRSMs introduced in the previous
work have a limitation that impedes their automation: all of their components
have to be non-negative in all reachable states. This might result in a LexRSM
not existing even for simple terminating programs. Our contributions are twofold.
First, we introduce a generalization of LexRSMs that allows for some components
to be negative. This standard feature of non-probabilistic termination proofs
was hitherto not known to be sound in the probabilistic setting, as the soundness
proof requires a careful analysis of the underlying stochastic process. Second,
we present polynomial-time algorithms using our generalized LexRSMs for proving
a.s. termination in broad classes of linear-arithmetic programs.'

text: The presence of a developed boundary layer decouples a glacier's response
from ambient conditions, suggesting that sensitivity to climate change is increased
by glacier retreat. To test this hypothesis, we explore six years of distributed
meteorological data on a small Swiss glacier in the period 2001–2022. Large glacier
fragmentation has occurred since 2001 (−35% area change up to 2022) coinciding
with notable frontal retreat, an observed switch from down‐glacier katabatic to
up‐glacier valley winds and an increased sensitivity (ratio) of on‐glacier to
off‐glacier temperature. As the glacier ceases to develop density‐driven katabatic
winds, sensible heat fluxes on the glacier are increasingly determined by the
conditions occurring outside the boundary layer of the glacier, sealing the glacier's
demise as the climate continues to warm and experience an increased frequency
of extreme summers.

text: In this paper, we study the eigenvalues and eigenvectors of the spiked invariant
multiplicative models when the randomness is from Haar matrices. We establish
the limits of the outlier eigenvalues λˆi and the generalized components (⟨v,uˆi⟩
for any deterministic vector v) of the outlier eigenvectors uˆi with optimal convergence
rates. Moreover, we prove that the non-outlier eigenvalues stick with those of
the unspiked matrices and the non-outlier eigenvectors are delocalized. The results
also hold near the so-called BBP transition and for degenerate spikes. On one
hand, our results can be regarded as a refinement of the counterparts of [12]
under additional regularity conditions. On the other hand, they can be viewed
as an analog of [34] by replacing the random matrix with i.i.d. entries with Haar
random matrix.

text: Germ granules, condensates of phase-separated RNA and protein, are organelles
that are essential for germline development in different organisms. The patterning
of the granules and their relevance for germ cell fate are not fully understood.
Combining three-dimensional in vivo structural and functional analyses, we study
the dynamic spatial organization of molecules within zebrafish germ granules.
We find that the localization of RNA molecules to the periphery of the granules,
where ribosomes are localized, depends on translational activity at this location.
In addition, we find that the vertebrate-specific Dead end (Dnd1) protein is essential
for nanos3 RNA localization at the condensates’ periphery. Accordingly, in the
absence of Dnd1, or when translation is inhibited, nanos3 RNA translocates into
the granule interior, away from the ribosomes, a process that is correlated with
the loss of germ cell fate. These findings highlight the relevance of sub-granule
compartmentalization for post-transcriptional control and its importance for preserving
germ cell totipotency.

text: The actin cortex is a complex cytoskeletal machinery that drives and responds
to changes in cell shape. It must generate or adapt to plasma membrane curvature
to facilitate diverse functions such as cell division, migration, and phagocytosis.
Due to the complex molecular makeup of the actin cortex, it remains unclear whether
actin networks are inherently able to sense and generate membrane curvature, or
whether they rely on their diverse binding partners to accomplish this. Here,
we show that curvature sensing is an inherent capability of branched actin networks
nucleated by Arp2/3 and VCA. We develop a robust method to encapsulate actin inside
giant unilamellar vesicles (GUVs) and assemble an actin cortex at the inner surface
of the GUV membrane. We show that actin forms a uniform and thin cortical layer
when present at high concentration and distinct patches associated with negative
membrane curvature at low concentration. Serendipitously, we find that the GUV
production method also produces dumbbell-shaped GUVs, which we explain using mathematical
modeling in terms of membrane hemifusion of nested GUVs. We find that branched
actin networks preferentially assemble at the neck of the dumbbells, which possess
a micrometer-range convex curvature comparable with the curvature of the actin
patches found in spherical GUVs. Minimal branched actin networks can thus sense
membrane curvature, which may help mammalian cells to robustly recruit actin to
curved membranes to facilitate diverse cellular functions such as cytokinesis
and migration.

text: We study direct integrals of quadratic and Dirichlet forms. We show that each
quasi-regular Dirichlet space over a probability space admits a unique representation
as a direct integral of irreducible Dirichlet spaces, quasi-regular for the same
underlying topology. The same holds for each quasi-regular strongly local Dirichlet
space over a metrizable Luzin σ-finite Radon measure space, and admitting carré
du champ operator. In this case, the representation is only projectively unique.

text: We study the large scale behavior of elliptic systems with stationary random
coefficient that have only slowly decaying correlations. To this aim we analyze
the so-called corrector equation, a degenerate elliptic equation posed in the
probability space. In this contribution, we use a parabolic approach and optimally
quantify the time decay of the semigroup. For the theoretical point of view, we
prove an optimal decay estimate of the gradient and flux of the corrector when
spatially averaged over a scale R larger than 1. For the numerical point of view,
our results provide convenient tools for the analysis of various numerical methods.
