text: The direct, solid state, and reversible conversion between heat and electricity
using thermoelectric devices finds numerous potential uses, especially around
room temperature. However, the relatively high material processing cost limits
their real applications. Silver selenide (Ag2Se) is one of the very few n-type
thermoelectric (TE) materials for room-temperature applications. Herein, we report
a room temperature, fast, and aqueous-phase synthesis approach to produce Ag2Se,
which can be extended to other metal chalcogenides. These materials reach TE figures
of merit (zT) of up to 0.76 at 380 K. To improve these values, bismuth sulfide
(Bi2S3) particles also prepared in an aqueous solution are incorporated into the
Ag2Se matrix. In this way, a series of Ag2Se/Bi2S3 composites with Bi2S3 wt %
of 0.5, 1.0, and 1.5 are prepared by solution blending and hot-press sintering.
The presence of Bi2S3 significantly improves the Seebeck coefficient and power
factor while at the same time decreasing the thermal conductivity with no apparent
drop in electrical conductivity. Thus, a maximum zT value of 0.96 is achieved
in the composites with 1.0 wt % Bi2S3 at 370 K. Furthermore, a high average zT
value (zTave) of 0.93 in the 300–390 K range is demonstrated.

text: We use a function field version of the Hardy–Littlewood circle method to study
the locus of free rational curves on an arbitrary smooth projective hypersurface
of sufficiently low degree. On the one hand this allows us to bound the dimension
of the singular locus of the moduli space of rational curves on such hypersurfaces
and, on the other hand, it sheds light on Peyre’s reformulation of the Batyrev–Manin
conjecture in terms of slopes with respect to the tangent bundle.

text: The ability to control the direction of scattered light is crucial to provide
flexibility and scalability for a wide range of on-chip applications, such as
integrated photonics, quantum information processing, and nonlinear optics. Tunable
directionality can be achieved by applying external magnetic fields that modify
optical selection rules, by using nonlinear effects, or interactions with vibrations.
However, these approaches are less suitable to control microwave photon propagation
inside integrated superconducting quantum devices. Here, we demonstrate on-demand
tunable directional scattering based on two periodically modulated transmon qubits
coupled to a transmission line at a fixed distance. By changing the relative phase
between the modulation tones, we realize unidirectional forward or backward photon
scattering. Such an in-situ switchable mirror represents a versatile tool for
intra- and inter-chip microwave photonic processors. In the future, a lattice
of qubits can be used to realize topological circuits that exhibit strong nonreciprocity
or chirality.

text: Quantum entanglement is a key resource in currently developed quantum technologies.
Sharing this fragile property between superconducting microwave circuits and optical
or atomic systems would enable new functionalities, but this has been hindered
by an energy scale mismatch of >104 and the resulting mutually imposed loss and
noise. In this work, we created and verified entanglement between microwave and
optical fields in a millikelvin environment. Using an optically pulsed superconducting
electro-optical device, we show entanglement between propagating microwave and
optical fields in the continuous variable domain. This achievement not only paves
the way for entanglement between superconducting circuits and telecom wavelength
light, but also has wide-ranging implications for hybrid quantum networks in the
context of modularization, scaling, sensing, and cross-platform verification.

text: "We study the representative volume element (RVE) method, which is a method
to approximately infer the effective behavior ahom of a stationary random medium.
The latter is described by a coefficient field a(x) generated from a given ensemble
⟨⋅⟩ and the corresponding linear elliptic operator −∇⋅a∇. In line with the theory
of homogenization, the method proceeds by computing d=3 correctors (d denoting
the space dimension). To be numerically tractable, this computation has to be
done on a finite domain: the so-called representative volume element, i.e., a
large box with, say, periodic boundary conditions. The main message of this article
is: Periodize the ensemble instead of its realizations. By this, we mean that
it is better to sample from a suitably periodized ensemble than to periodically
extend the restriction of a realization a(x) from the whole-space ensemble ⟨⋅⟩.
We make this point by investigating the bias (or systematic error), i.e., the
difference between ahom and the expected value of the RVE method, in terms of
its scaling w.r.t. the lateral size L of the box. In case of periodizing a(x),
we heuristically argue that this error is generically O(L−1). In case of a suitable
periodization of ⟨⋅⟩\r\n, we rigorously show that it is O(L−d). In fact, we give
a characterization of the leading-order error term for both strategies and argue
that even in the isotropic case it is generically non-degenerate. We carry out
the rigorous analysis in the convenient setting of ensembles ⟨⋅⟩\r\n of Gaussian
type, which allow for a straightforward periodization, passing via the (integrable)
covariance function. This setting has also the advantage of making the Price theorem
and the Malliavin calculus available for optimal stochastic estimates of correctors.
We actually need control of second-order correctors to capture the leading-order
error term. This is due to inversion symmetry when applying the two-scale expansion
to the Green function. As a bonus, we present a stream-lined strategy to estimate
the error in a higher-order two-scale expansion of the Green function."

text: Brachyury, a member of T-box gene family, is widely known for its major role
in mesoderm specification in bilaterians. It is also present in non-bilaterian
metazoans, such as cnidarians, where it acts as a component of an axial patterning
system. In this study, we present a phylogenetic analysis of Brachyury genes within
phylum Cnidaria, investigate differential expression and address a functional
framework of Brachyury paralogs in hydrozoan Dynamena pumila. Our analysis indicates
two duplication events of Brachyury within the cnidarian lineage. The first duplication
likely appeared in the medusozoan ancestor, resulting in two copies in medusozoans,
while the second duplication arose in the hydrozoan ancestor, resulting in three
copies in hydrozoans. Brachyury1 and 2 display a conservative expression pattern
marking the oral pole of the body axis in D. pumila. On the contrary, Brachyury3
expression was detected in scattered presumably nerve cells of the D. pumila larva.
Pharmacological modulations indicated that Brachyury3 is not under regulation
of cWnt signaling in contrast to the other two Brachyury genes. Divergence in
expression patterns and regulation suggest neofunctionalization of Brachyury3
in hydrozoans.

text: "We consider the spin-\r\n1\r\n2\r\n Heisenberg chain (XXX model) weakly perturbed
away from integrability by an isotropic next-to-nearest neighbor exchange interaction.
Recently, it was conjectured that this model possesses an infinite tower of quasiconserved
integrals of motion (charges) [D. Kurlov et al., Phys. Rev. B 105, 104302 (2022)].
In this work we first test this conjecture by investigating how the norm of the
adiabatic gauge potential (AGP) scales with the system size, which is known to
be a remarkably accurate measure of chaos. We find that for the perturbed XXX
chain the behavior of the AGP norm corresponds to neither an integrable nor a
chaotic regime, which supports the conjectured quasi-integrability of the model.
We then prove the conjecture and explicitly construct the infinite set of quasiconserved
charges. Our proof relies on the fact that the XXX chain perturbed by next-to-nearest
exchange interaction can be viewed as a truncation of an integrable long-range
deformation of the Heisenberg spin chain."

text: The primary cell wall is a fundamental plant constituent that is flexible
but sufficiently rigid to support the plant cell shape. Although many studies
have demonstrated that reactive oxygen species (ROS) serve as important signaling
messengers to modify the cell wall structure and affect cellular growth, the regulatory
mechanism underlying the spatial-temporal regulation of ROS activity for cell
wall maintenance remains largely unclear. Here, we demonstrate the role of the
Arabidopsis (Arabidopsis thaliana) multicopper oxidase-like protein skewed 5 (SKU5)
and its homolog SKU5-similar 1 (SKS1) in root cell wall formation through modulating
ROS homeostasis. Loss of SKU5 and SKS1 function resulted in aberrant division
planes, protruding cell walls, ectopic deposition of iron, and reduced nicotinamide
adeninedinucleotide phosphate (NADPH) oxidase-dependent ROS overproduction in
the root epidermis–cortex and cortex–endodermis junctions. A decrease in ROS level
or inhibition of NADPH oxidase activity rescued the cell wall defects of sku5
sks1 double mutants. SKU5 and SKS1 proteins were activated by iron treatment,
and iron over-accumulated in the walls between the root epidermis and cortex cell
layers of sku5 sks1. The glycosylphosphatidylinositol-anchored motif was crucial
for membrane association and functionality of SKU5 and SKS1. Overall, our results
identified SKU5 and SKS1 as regulators of ROS at the cell surface for regulation
of cell wall structure and root cell growth.

text: In Gram negative bacteria, the multiple antibiotic resistance or mar operon,
is known to control the expression of multi-drug efflux genes that protect bacteria
from a wide range of drugs. As many different chemical compounds can induce this
operon, identifying the parameters that govern the dynamics of its induction is
crucial to better characterize the processes of tolerance and resistance. Most
experiments have assumed that the properties of the mar transcriptional network
can be inferred from population measurements. However, measurements from an asynchronous
population of cells can mask underlying phenotypic variations of single cells.
We monitored the activity of the mar promoter in single Escherichia coli cells
in linear micro-colonies and established that the response to a steady level of
inducer was most heterogeneous within individual colonies for an intermediate
value of inducer. Specifically, sub-lineages defined by contiguous daughter-cells
exhibited similar promoter activity, whereas activity was greatly variable between
different sub-lineages. Specific sub-trees of uniform promoter activity persisted
over several generations. Statistical analyses of the lineages suggest that the
presence of these sub-trees is the signature of an inducible memory of the promoter
state that is transmitted from mother to daughter cells. This single-cell study
reveals that the degree of epigenetic inheritance changes as a function of inducer
concentration, suggesting that phenotypic inheritance may be an inducible phenotype.

text: The formation of amyloid fibrils is a general class of protein self-assembly
behaviour, which is associated with both functional biology and the development
of a number of disorders, such as Alzheimer and Parkinson diseases. In this Review,
we discuss how general physical concepts from the study of phase transitions can
be used to illuminate the fundamental mechanisms of amyloid self-assembly. We
summarize progress in the efforts to describe the essential biophysical features
of amyloid self-assembly as a nucleation-and-growth process and discuss how master
equation approaches can reveal the key molecular pathways underlying this process,
including the role of secondary nucleation. Additionally, we outline how non-classical
aspects of aggregate formation involving oligomers or biomolecular condensates
have emerged, inspiring developments in understanding, modelling and modulating
complex protein assembly pathways. Finally, we consider how these concepts can
be applied to kinetics-based drug discovery and therapeutic design to develop
treatments for protein aggregation diseases.

text: Dynamic reorganization of the cytoplasm is key to many core cellular processes,
such as cell division, cell migration, and cell polarization. Cytoskeletal rearrangements
are thought to constitute the main drivers of cytoplasmic flows and reorganization.
In contrast, remarkably little is known about how dynamic changes in size and
shape of cell organelles affect cytoplasmic organization. Here, we show that within
the maturing zebrafish oocyte, the surface localization of exocytosis-competent
cortical granules (Cgs) upon germinal vesicle breakdown (GVBD) is achieved by
the combined activities of yolk granule (Yg) fusion and microtubule aster formation
and translocation. We find that Cgs are moved towards the oocyte surface through
radially outward cytoplasmic flows induced by Ygs fusing and compacting towards
the oocyte center in response to GVBD. We further show that vesicles decorated
with the small Rab GTPase Rab11, a master regulator of vesicular trafficking and
exocytosis, accumulate together with Cgs at the oocyte surface. This accumulation
is achieved by Rab11-positive vesicles being transported by acentrosomal microtubule
asters, the formation of which is induced by the release of CyclinB/Cdk1 upon
GVBD, and which display a net movement towards the oocyte surface by preferentially
binding to the oocyte actin cortex. We finally demonstrate that the decoration
of Cgs by Rab11 at the oocyte surface is needed for Cg exocytosis and subsequent
chorion elevation, a process central in egg activation. Collectively, these findings
unravel a yet unrecognized role of organelle fusion, functioning together with
cytoskeletal rearrangements, in orchestrating cytoplasmic organization during
oocyte maturation.

text: "Nominally identical materials exchange net electric charge during contact
through a mechanism that is still debated. ‘Mosaic models’, in which surfaces
are presumed to consist of a random patchwork of microscopic donor/acceptor sites,
offer an appealing explanation for this phenomenon. However, recent experiments
have shown that global differences persist even between same-material samples,
which the standard mosaic framework does not account for. Here, we expand the
mosaic framework by incorporating global differences in the densities of donor/acceptor
sites. We develop\r\nan analytical model, backed by numerical simulations, that
smoothly connects the global and deterministic charge transfer of different materials
to the local and stochastic mosaic picture normally associated with identical
materials. Going further, we extend our model to explain the effect of contact
asymmetries during sliding, providing a plausible explanation for reversal of
charging sign that has been observed experimentally."

text: 'To interpret the sensory environment, the brain combines ambiguous sensory
measurements with knowledge that reflects context-specific prior experience. But
environmental contexts can change abruptly and unpredictably, resulting in uncertainty
about the current context. Here we address two questions: how should context-specific
prior knowledge optimally guide the interpretation of sensory stimuli in changing
environments, and do human decision-making strategies resemble this optimum? We
probe these questions with a task in which subjects report the orientation of
ambiguous visual stimuli that were drawn from three dynamically switching distributions,
representing different environmental contexts. We derive predictions for an ideal
Bayesian observer that leverages knowledge about the statistical structure of
the task to maximize decision accuracy, including knowledge about the dynamics
of the environment. We show that its decisions are biased by the dynamically changing
task context. The magnitude of this decision bias depends on the observer’s continually
evolving belief about the current context. The model therefore not only predicts
that decision bias will grow as the context is indicated more reliably, but also
as the stability of the environment increases, and as the number of trials since
the last context switch grows. Analysis of human choice data validates all three
predictions, suggesting that the brain leverages knowledge of the statistical
structure of environmental change when interpreting ambiguous sensory signals.'

text: The potential of immune-evasive mutation accumulation in the SARS-CoV-2 virus
has led to its rapid spread, causing over 600 million confirmed cases and more
than 6.5 million confirmed deaths. The huge demand for the rapid development and
deployment of low-cost and effective vaccines against emerging variants has renewed
interest in DNA vaccine technology. Here, we report the rapid generation and immunological
evaluation of novel DNA vaccine candidates against the Wuhan-Hu-1 and Omicron
variants based on the RBD protein fused with the Potato virus X coat protein (PVXCP).
The delivery of DNA vaccines using electroporation in a two-dose regimen induced
high-antibody titers and profound cellular responses in mice. The antibody titers
induced against the Omicron variant of the vaccine were sufficient for effective
protection against both Omicron and Wuhan-Hu-1 virus infections. The PVXCP protein
in the vaccine construct shifted the immune response to the favorable Th1-like
type and provided the oligomerization of RBD-PVXCP protein. Naked DNA delivery
by needle-free injection allowed us to achieve antibody titers comparable with
mRNA-LNP delivery in rabbits. These data identify the RBD-PVXCP DNA vaccine platform
as a promising solution for robust and effective SARS-CoV-2 protection, supporting
further translational study.

text: AgSbSe2 is a promising thermoelectric (TE) p-type material for applications
in the middle-temperature range. AgSbSe2 is characterized by relatively low thermal
conductivities and high Seebeck coefficients, but its main limitation is moderate
electrical conductivity. Herein, we detail an efficient and scalable hot-injection
synthesis route to produce AgSbSe2 nanocrystals (NCs). To increase the carrier
concentration and improve the electrical conductivity, these NCs are doped with
Sn2+ on Sb3+ sites. Upon processing, the Sn2+ chemical state is conserved using
a reducing NaBH4 solution to displace the organic ligand and anneal the material
under a forming gas flow. The TE properties of the dense materials obtained from
the consolidation of the NCs using a hot pressing are then characterized. The
presence of Sn2+ ions replacing Sb3+ significantly increases the charge carrier
concentration and, consequently, the electrical conductivity. Opportunely, the
measured Seebeck coefficient varied within a small range upon Sn doping. The excellent
performance obtained when Sn2+ ions are prevented from oxidation is rationalized
by modeling the system. Calculated band structures disclosed that Sn doping induces
convergence of the AgSbSe2 valence bands, accounting for an enhanced electronic
effective mass. The dramatically enhanced carrier transport leads to a maximized
power factor for AgSb0.98Sn0.02Se2 of 0.63 mW m–1 K–2 at 640 K. Thermally, phonon
scattering is significantly enhanced in the NC-based materials, yielding an ultralow
thermal conductivity of 0.3 W mK–1 at 666 K. Overall, a record-high figure of
merit (zT) is obtained at 666 K for AgSb0.98Sn0.02Se2 at zT = 1.37, well above
the values obtained for undoped AgSbSe2, at zT = 0.58 and state-of-art Pb- and
Te-free materials, which makes AgSb0.98Sn0.02Se2 an excellent p-type candidate
for medium-temperature TE applications.

text: We study ab initio approaches for calculating x-ray Thomson scattering spectra
from density functional theory molecular dynamics simulations based on a modified
Chihara formula that expresses the inelastic contribution in terms of the dielectric
function. We study the electronic dynamic structure factor computed from the Mermin
dielectric function using an ab initio electron-ion collision frequency in comparison
to computations using a linear-response time-dependent density functional theory
(LR-TDDFT) framework for hydrogen and beryllium and investigate the dispersion
of free-free and bound-free contributions to the scattering signal. A separate
treatment of these contributions, where only the free-free part follows the Mermin
dispersion, shows good agreement with LR-TDDFT results for ambient-density beryllium,
but breaks down for highly compressed matter where the bound states become pressure
ionized. LR-TDDFT is used to reanalyze x-ray Thomson scattering experiments on
beryllium demonstrating strong deviations from the plasma conditions inferred
with traditional analytic models at small scattering angles.

text: We study the impact of finite-range physics on the zero-range-model analysis
of three-body recombination in ultracold atoms. We find that temperature dependence
of the zero-range parameters can vary from one set of measurements to another
as it may be driven by the distribution of error bars in the experiment, and not
by the underlying three-body physics. To study finite-temperature effects in three-body
recombination beyond the zero-range physics, we introduce and examine a finite-range
model based upon a hyperspherical formalism. The systematic error discussed in
this Letter may provide a significant contribution to the error bars of measured
three-body parameters.

text: The El Niño-Southern Oscillation (ENSO) and the Indian summer monsoon (ISM,
or monsoon) are two giants of tropical climate. Here we assess the future evolution
of the ENSO-monsoon teleconnection in climate simulations with idealized forcing
of CO2 increment at a rate of 1% year-1 starting from a present-day condition
(367 p.p.m.) until quadrupling. We find a monotonous weakening of the ENSO-monsoon
teleconnection with the increase in CO2. Increased co-occurrences of El Niño and
positive Indian Ocean Dipoles (pIODs) in a warmer climate weaken the teleconnection.
Co-occurrences of El Niño and pIOD are attributable to mean sea surface temperature
(SST) warming that resembles a pIOD-type warming pattern in the Indian Ocean and
an El Niño-type warming in the Pacific. Since ENSO is a critical precursor of
the strength of the Indian monsoon, a weakening of this relation may mean a less
predictable Indian monsoon in a warmer climate.

text: Experimental evolution studies are powerful approaches to examine the evolutionary
history of lab populations. Such studies have shed light on how selection changes
phenotypes and genotypes. Most of these studies have not examined the time course
of adaptation under sexual selection manipulation, by resequencing the populations’
genomes at multiple time points. Here, we analyze allele frequency trajectories
in Drosophila pseudoobscura where we altered their sexual selection regime for
200 generations and sequenced pooled populations at 5 time points. The intensity
of sexual selection was either relaxed in monogamous populations (M) or elevated
in polyandrous lines (E). We present a comprehensive study of how selection alters
population genetics parameters at the chromosome and gene level. We investigate
differences in the effective population size—Ne—between the treatments, and perform
a genome-wide scan to identify signatures of selection from the time-series data.
We found genomic signatures of adaptation to both regimes in D. pseudoobscura.
There are more significant variants in E lines as expected from stronger sexual
selection. However, we found that the response on the X chromosome was substantial
in both treatments, more pronounced in E and restricted to the more recently sex-linked
chromosome arm XR in M. In the first generations of experimental evolution, we
estimate Ne to be lower on the X in E lines, which might indicate a swift adaptive
response at the onset of selection. Additionally, the third chromosome was affected
by elevated polyandry whereby its distal end harbors a region showing a strong
signal of adaptive evolution especially in E lines.

text: The self-assembly of nanoparticles driven by small molecules or ions may produce
colloidal superlattices with features and properties reminiscent of those of metals
or semiconductors. However, to what extent the properties of such supramolecular
crystals actually resemble those of atomic materials often remains unclear. Here,
we present coarse-grained molecular simulations explicitly demonstrating how a
behavior evocative of that of semiconductors may emerge in a colloidal superlattice.
As a case study, we focus on gold nanoparticles bearing positively charged groups
that self-assemble into FCC crystals via mediation by citrate counterions. In
silico ohmic experiments show how the dynamically diverse behavior of the ions
in different superlattice domains allows the opening of conductive ionic gates
above certain levels of applied electric fields. The observed binary conductive/nonconductive
behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular
level, crossing the “band gap” requires a sufficient electrostatic stimulus to
break the intermolecular interactions and make ions diffuse throughout the superlattice’s
cavities.

text: Asteroseismology has transformed stellar astrophysics. Red giant asteroseismology
is a prime example, with oscillation periods and amplitudes that are readily detectable
with time-domain space-based telescopes. These oscillations can be used to infer
masses, ages and radii for large numbers of stars, providing unique constraints
on stellar populations in our galaxy. The cadence, duration, and spatial resolution
of the Roman galactic bulge time-domain survey (GBTDS) are well-suited for asteroseismology
and will probe an important population not studied by prior missions. We identify
photometric precision as a key requirement for realizing the potential of asteroseismology
with Roman. A precision of 1 mmag per 15-min cadence or better for saturated stars
will enable detections of the populous red clump star population in the Galactic
bulge. If the survey efficiency is better than expected, we argue for repeat observations
of the same fields to improve photometric precision, or covering additional fields
to expand the stellar population reach if the photometric precision for saturated
stars is better than 1 mmag. Asteroseismology is relatively insensitive to the
timing of the observations during the mission, and the prime red clump targets
can be observed in a single 70 day campaign in any given field. Complementary
stellar characterization, particularly astrometry tied to the Gaia system, will
also dramatically expand the diagnostic power of asteroseismology. We also highlight
synergies to Roman GBTDS exoplanet science using transits and microlensing.

text: 'Integrating light-sensitive molecules within nanoparticle (NP) assemblies
is an attractive approach to fabricate new photoresponsive nanomaterials. Here,
we describe the concept of photocleavable anionic glue (PAG): small trianions
capable of mediating interactions between (and inducing the aggregation of) cationic
NPs by means of electrostatic interactions. Exposure to light converts PAGs into
dianionic products incapable of maintaining the NPs in an assembled state, resulting
in light-triggered disassembly of NP aggregates. To demonstrate the proof-of-concept,
we work with an organic PAG incorporating the UV-cleavable o-nitrobenzyl moiety
and an inorganic PAG, the photosensitive trioxalatocobaltate(III) complex, which
absorbs light across the entire visible spectrum. Both PAGs were used to prepare
either amorphous NP assemblies or regular superlattices with a long-range NP order.
These NP aggregates disassembled rapidly upon light exposure for a specific time,
which could be tuned by the incident light wavelength or the amount of PAG used.
Selective excitation of the inorganic PAG in a system combining the two PAGs results
in a photodecomposition product that deactivates the organic PAG, enabling nontrivial
disassembly profiles under a single type of external stimulus.'

text: "Most energy in humans is produced in form of ATP by the mitochondrial respiratory
chain consisting of several protein assemblies embedded into lipid membrane (complexes
I-V). Complex I is the first and the largest enzyme of the respiratory chain which
is essential for energy production. It couples the transfer of two electrons from
NADH to ubiquinone with proton translocation across bacterial or inner mitochondrial
membrane. The coupling mechanism between electron transfer and proton translocation
is one of the biggest enigma in bioenergetics and structural biology. Even though
the enzyme has been studied for decades, only recent technological advances in
cryo-EM allowed its extensive structural investigation. \r\n\r\nComplex I from
E.coli appears to be of special importance because it is a perfect model system
with a rich mutant library, however the structure of the entire complex was unknown.
In this thesis I have resolved structures of the minimal complex I version from
E. coli in different states including reduced, inhibited, under reaction turnover
and several others. Extensive structural analyses of these structures and comparison
to structures from other species allowed to derive general features of conformational
dynamics and propose a universal coupling mechanism. The mechanism is straightforward,
robust and consistent with decades of experimental data available for complex
I from different species. \r\n\r\nCyanobacterial NDH (cyanobacterial complex I)
is a part of broad complex I superfamily and was studied as well in this thesis.
It plays an important role in cyclic electron transfer (CET), during which electrons
are cycled within PSI through ferredoxin and plastoquinone to generate proton
gradient without NADPH production. Here, I solved structure of NDH and revealed
additional state, which was not observed before. The novel “resting” state allowed
to propose the mechanism of CET regulation. Moreover, conformational dynamics
of NDH resembles one in complex I which suggest more broad universality of the
proposed coupling mechanism.\r\n\r\nIn summary, results presented here helped
to interpret decades of experimental data for complex I and contributed to fundamental
mechanistic understanding of protein function.\r\n"

text: "Deep learning has become an integral part of a large number of important
applications, and many of the recent breakthroughs have been enabled by the ability
to train very large models, capable to capture complex patterns and relationships
from the data. At the same time, the massive sizes of modern deep learning models
have made their deployment to smaller devices more challenging; this is particularly
important, as in many applications the users rely on accurate deep learning predictions,
but they only have access to devices with limited memory and compute power. One
solution to this problem is to prune neural networks, by setting as many of their
parameters as possible to zero, to obtain accurate sparse models with lower memory
footprint. Despite the great research progress in obtaining sparse models that
preserve accuracy, while satisfying memory and computational constraints, there
are still many challenges associated with efficiently training sparse models,
as well as understanding their generalization properties.\r\n\r\nThe focus of
this thesis is to investigate how the training process of sparse models can be
made more efficient, and to understand the differences between sparse and dense
models in terms of how well they can generalize to changes in the data distribution.
We first study a method for co-training sparse and dense models, at a lower cost
compared to regular training. With our method we can obtain very accurate sparse
networks, and dense models that can recover the baseline accuracy. Furthermore,
we are able to more easily analyze the differences, at prediction level, between
the sparse-dense model pairs. Next, we investigate the generalization properties
of sparse neural networks in more detail, by studying how well different sparse
models trained on a larger task can adapt to smaller, more specialized tasks,
in a transfer learning scenario. Our analysis across multiple pruning methods
and sparsity levels reveals that sparse models provide features that can transfer
similarly to or better than the dense baseline. However, the choice of the pruning
method plays an important role, and can influence the results when the features
are fixed (linear finetuning), or when they are allowed to adapt to the new task
(full finetuning). Using sparse models with fixed masks for finetuning on new
tasks has an important practical advantage, as it enables training neural networks
on smaller devices. However, one drawback of current pruning methods is that the
entire training cycle has to be repeated to obtain the initial sparse model, for
every sparsity target; in consequence, the entire training process is costly and
also multiple models need to be stored. In the last part of the thesis we propose
a method that can train accurate dense models that are compressible in a single
step, to multiple sparsity levels, without additional finetuning. Our method results
in sparse models that can be competitive with existing pruning methods, and which
can also successfully generalize to new tasks."

text: "Pattern formation is of great importance for its contribution across different
biological behaviours. During developmental processes for example, patterns of
chemical gradients are\r\nestablished to determine cell fate and complex tissue
patterns emerge to define structures such\r\nas limbs and vascular networks. Patterns
are also seen in collectively migrating groups, for\r\ninstance traveling waves
of density emerging in moving animal flocks as well as collectively migrating
cells and tissues. To what extent these biological patterns arise spontaneously
through\r\nthe local interaction of individual constituents or are dictated by
higher level instructions is\r\nstill an open question however there is evidence
for the involvement of both types of process.\r\nWhere patterns arise spontaneously
there is a long standing interest in how far the interplay\r\nof mechanics, e.g.
force generation and deformation, and chemistry, e.g. gene regulation\r\nand signaling,
contributes to the behaviour. This is because many systems are able to both\r\nchemically
regulate mechanical force production and chemically sense mechanical deformation,\r\nforming
mechano-chemical feedback loops which can potentially become unstable towards\r\nspatio
and/or temporal patterning.\r\nWe work with experimental collaborators to investigate
the possibility that this type of\r\ninteraction drives pattern formation in biological
systems at different scales. We focus first on\r\ntissue-level ERK-density waves
observed during the wound healing response across different\r\nsystems where many
previous studies have proposed that patterns depend on polarized cell\r\nmigration
and arise from a mechanical flocking-like mechanism. By combining theory with\r\nmechanical
and optogenetic perturbation experiments on in vitro monolayers we instead find\r\nevidence
for mechanochemical pattern formation involving only scalar bilateral feedbacks\r\nbetween
ERK signaling and cell contraction. We perform further modeling and experiment\r\nto
study how this instability couples with polar cell migration in order to produce
a robust\r\nand efficient wound healing response. In a following chapter we implement
ERK-density\r\ncoupling and cell migration in a 2D active vertex model to investigate
the interaction of\r\nERK-density patterning with different tissue rheologies
and find that the spatio-temporal\r\ndynamics are able to both locally and globally
fluidize a tissue across the solid-fluid glass\r\ntransition. In a last chapter
we move towards lower spatial scales in the context of subcellular\r\npatterning
of the cell cytoskeleton where we investigate the transition between phases of\r\nspatially
homogeneous temporal oscillations and chaotic spatio-temporal patterning in the\r\ndynamics
of myosin and ROCK activities (a motor component of the actomyosin cytoskeleton\r\nand
its activator). Experimental evidence supports an intrinsic chemical oscillator
which we\r\nencode in a reaction model and couple to a contractile active gel
description of the cell cortex.\r\nThe model exhibits phases of chemical oscillations
and contractile spatial patterning which\r\nreproduce many features of the dynamics
seen in Drosophila oocyte epithelia in vivo. However,\r\nadditional pharmacological
perturbations to inhibit myosin contractility leaves the role of\r\ncontractile
instability unclear. We discuss alternative hypotheses and investigate the possibility\r\nof
reaction-diffusion instability."

text: The many-body localization (MBL) proximity effect is an intriguing phenomenon
where a thermal bath localizes due to the interaction with a disordered system.
The interplay of thermal and nonergodic behavior in these systems gives rise to
a rich phase diagram, whose exploration is an active field of research. In this
paper, we study a bosonic Hubbard model featuring two particle species representing
the bath and the disordered system. Using state-of-the-art numerical techniques,
we investigate the dynamics of the model in different regimes, based on which
we obtain a tentative phase diagram as a function of coupling strength and bath
size. When the bath is composed of a single particle, we observe clear signatures
of a transition from an MBL proximity effect to a delocalized phase. Increasing
the bath size, however, its thermalizing effect becomes stronger and eventually
the whole system delocalizes in the range of moderate interaction strengths studied.
In this regime, we characterize particle transport, revealing diffusive behavior
of the originally localized bosons.

text: We present a low-scaling diagrammatic Monte Carlo approach to molecular correlation
energies. Using combinatorial graph theory to encode many-body Hugenholtz diagrams,
we sample the Møller-Plesset (MPn) perturbation series, obtaining accurate correlation
energies up to n=5, with quadratic scaling in the number of basis functions. Our
technique reduces the computational complexity of the molecular many-fermion correlation
problem, opening up the possibility of low-scaling, accurate stochastic computations
for a wide class of many-body systems described by Hugenholtz diagrams.

text: Cooperative disease defense emerges as group-level collective behavior, yet
how group members make the underlying individual decisions is poorly understood.
Using garden ants and fungal pathogens as an experimental model, we derive the
rules governing individual ant grooming choices and show how they produce colony-level
hygiene. Time-resolved behavioral analysis, pathogen quantification, and probabilistic
modeling reveal that ants increase grooming and preferentially target highly-infectious
individuals when perceiving high pathogen load, but transiently suppress grooming
after having been groomed by nestmates. Ants thus react to both, the infectivity
of others and the social feedback they receive on their own contagiousness. While
inferred solely from momentary ant decisions, these behavioral rules quantitatively
predict hour-long experimental dynamics, and synergistically combine into efficient
colony-wide pathogen removal. Our analyses show that noisy individual decisions
based on only local, incomplete, yet dynamically-updated information on pathogen
threat and social feedback can lead to potent collective disease defense.

text: 'High-performance semiconductors rely upon precise control of heat and charge
transport. This can be achieved by precisely engineering defects in polycrystalline
solids. There are multiple approaches to preparing such polycrystalline semiconductors,
and the transformation of solution-processed colloidal nanoparticles is appealing
because colloidal nanoparticles combine low cost with structural and compositional
tunability along with rich surface chemistry. However, the multiple processes
from nanoparticle synthesis to the final bulk nanocomposites are very complex.
They involve nanoparticle purification, post-synthetic modifications, and finally
consolidation (thermal treatments and densification). All these properties dictate
the final material’s composition and microstructure, ultimately affecting its
functional properties. This thesis explores the synthesis, surface chemistry and
consolidation of colloidal semiconductor nanoparticles into dense solids. In particular,
the transformations that take place during these processes, and their effect on
the material’s transport properties are evaluated. '

text: Following up on the recent work on lower Ricci curvature bounds for quantum
systems, we introduce two noncommutative versions of curvature-dimension bounds
for symmetric quantum Markov semigroups over matrix algebras. Under suitable such
curvature-dimension conditions, we prove a family of dimension-dependent functional
inequalities, a version of the Bonnet–Myers theorem and concavity of entropy power
in the noncommutative setting. We also provide examples satisfying certain curvature-dimension
conditions, including Schur multipliers over matrix algebras, Herz–Schur multipliers
over group algebras and generalized depolarizing semigroups.

text: In 1998 Burago and Kleiner and (independently) McMullen gave examples of separated
nets in Euclidean space which are non-bilipschitz equivalent to the integer lattice.
We study weaker notions of equivalence of separated nets and demonstrate that
such notions also give rise to distinct equivalence classes. Put differently,
we find occurrences of particularly strong divergence of separated nets from the
integer lattice. Our approach generalises that of Burago and Kleiner and McMullen
which takes place largely in a continuous setting. Existence of irregular separated
nets is verified via the existence of non-realisable density functions ρ:[0,1]d→(0,∞).
In the present work we obtain stronger types of non-realisable densities.

text: The power factor of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)
(PEDOT:PSS) film can be significantly improved by optimizing the oxidation level
of the film in oxidation and reduction processes. However, precise control over
the oxidation and reduction effects in PEDOT:PSS remains a challenge, which greatly
sacrifices both S and σ. Here, we propose a two-step post-treatment using a mixture
of ethylene glycol (EG) and Arginine (Arg) and sulfuric acid (H2SO4) in sequence
to engineer high-performance PEDOT:PSS thermoelectric films. The high-polarity
EG dopant removes the excess non-ionized PSS and induces benzenoid-to-quinoid
conformational change in the PEDOT:PSS films. In particular, basic amino acid
Arg tunes the oxidation level of PEDOT:PSS and prevents the films from over-oxidation
during H2SO4 post-treatment, leading to increased S. The following H2SO4 post-treatment
further induces highly orientated lamellar stacking microstructures to increase
σ, yielding a maximum power factor of 170.6 μW m−1 K−2 at 460 K. Moreover, a novel
trigonal-shape thermoelectric device is designed and assembled by the as-prepared
PEDOT:PSS films in order to harvest heat via a vertical temperature gradient.
An output power density of 33 μW cm−2 is generated at a temperature difference
of 40 K, showing the potential application for low-grade wearable electronic devices.

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.

text: Following E. Wigner’s original vision, we prove that sampling the eigenvalue
gaps within the bulk spectrum of a fixed (deformed) Wigner matrix H yields the
celebrated Wigner-Dyson-Mehta universal statistics with high probability. Similarly,
we prove universality for a monoparametric family of deformed Wigner matrices
H+xA with a deterministic Hermitian matrix A and a fixed Wigner matrix H, just
using the randomness of a single scalar real random variable x. Both results constitute
quenched versions of bulk universality that has so far only been proven in annealed
sense with respect to the probability space of the matrix ensemble.

text: High carrier mobility is critical to improving thermoelectric performance
over a broad temperature range. However, traditional doping inevitably deteriorates
carrier mobility. Herein, we develop a strategy for fine tuning of defects to
improve carrier mobility. To begin, n-type PbTe is created by compensating for
the intrinsic Pb vacancy in bare PbTe. Excess Pb2+ reduces vacancy scattering,
resulting in a high carrier mobility of ∼3400 cm2 V–1 s–1. Then, excess Ag is
introduced to compensate for the remaining intrinsic Pb vacancies. We find that
excess Ag exhibits a dynamic doping process with increasing temperatures, increasing
both the carrier concentration and carrier mobility throughout a wide temperature
range; specifically, an ultrahigh carrier mobility ∼7300 cm2 V–1 s–1 is obtained
for Pb1.01Te + 0.002Ag at 300 K. Moreover, the dynamic doping-induced high carrier
concentration suppresses the bipolar thermal conductivity at high temperatures.
The final step is using iodine to optimize the carrier concentration to ∼1019
cm–3. Ultimately, a maximum ZT value of ∼1.5 and a large average ZTave value of
∼1.0 at 300–773 K are obtained for Pb1.01Te0.998I0.002 + 0.002Ag. These findings
demonstrate that fine tuning of defects with <0.5% impurities can remarkably enhance
carrier mobility and improve thermoelectric performance.

text: 'A simple drawing D(G) of a graph G is one where each pair of edges share
at most one point: either a common endpoint or a proper crossing. An edge e in
the complement of G can be inserted into D(G) if there exists a simple drawing
of G+e extending D(G). As a result of Levi’s Enlargement Lemma, if a drawing is
rectilinear (pseudolinear), that is, the edges can be extended into an arrangement
of lines (pseudolines), then any edge in the complement of G can be inserted.
In contrast, we show that it is NP-complete to decide whether one edge can be
inserted into a simple drawing. This remains true even if we assume that the drawing
is pseudocircular, that is, the edges can be extended to an arrangement of pseudocircles.
On the positive side, we show that, given an arrangement of pseudocircles A and
a pseudosegment σ, it can be decided in polynomial time whether there exists a
pseudocircle Φσ extending σ for which A∪{Φσ} is again an arrangement of pseudocircles.'

text: 'The design and implementation of efficient concurrent data structures has
seen significant attention. However, most of this work has focused on concurrent
data structures providing good worst-case guarantees, although, in real workloads,
objects are often accessed at different rates. Efficient distribution-adaptive
data structures, such as splay-trees, are known in the sequential case; however,
they often are hard to translate efficiently to the concurrent case. We investigate
distribution-adaptive concurrent data structures, and propose a new design called
the splay-list. At a high level, the splay-list is similar to a standard skip-list,
with the key distinction that the height of each element adapts dynamically to
its access rate: popular elements “move up,” whereas rarely-accessed elements
decrease in height. We show that the splay-list provides order-optimal amortized
complexity bounds for a subset of operations, while being amenable to efficient
concurrent implementation. Experiments show that the splay-list can leverage distribution-adaptivity
for performance, and can outperform the only previously-known distribution-adaptive
concurrent design in certain workloads.'

abstract:
- lang: eng
text: The term “haplotype block” is commonly used in the developing field of haplotype-based
inference methods. We argue that the term should be defined based on the structure
of the Ancestral Recombination Graph (ARG), which contains complete information
on the ancestry of a sample. We use simulated examples to demonstrate key features
of the relationship between haplotype blocks and ancestral structure, emphasizing
the stochasticity of the processes that generate them. Even the simplest cases
of neutrality or of a “hard” selective sweep produce a rich structure, often missed
by commonly used statistics. We highlight a number of novel methods for inferring
haplotype structure, based on the full ARG, or on a sequence of trees, and illustrate
how they can be used to define haplotype blocks using an empirical data set. While
the advent of new, computationally efficient methods makes it possible to apply
these concepts broadly, they (and additional new methods) could benefit from adding
features to explore haplotype blocks, as we define them. Understanding and applying
the concept of the haplotype block will be essential to fully exploit long and
linked-read sequencing technologies.

text: 'Probing the dynamics of aromatic side chains provides important insights
into the behavior of a protein because flips of aromatic rings in a protein’s
hydrophobic core report on breathing motion involving a large part of the protein.
Inherently invisible to crystallography, aromatic motions have been primarily
studied by solution NMR. The question how packing of proteins in crystals affects
ring flips has, thus, remained largely unexplored. Here we apply magic-angle spinning
NMR, advanced phenylalanine 1H-13C/2H isotope labeling and MD simulation to a
protein in three different crystal packing environments to shed light onto possible
impact of packing on ring flips. The flips of the two Phe residues in ubiquitin,
both surface exposed, appear remarkably conserved in the different crystal forms,
even though the intermolecular packing is quite different: Phe4 flips on a ca.
10–20 ns time scale, and Phe45 are broadened in all crystals, presumably due to
µs motion. Our findings suggest that intramolecular influences are more important
for ring flips than intermolecular (packing) effects.'

text: Small GTPases play essential roles in the organization of eukaryotic cells.
In recent years, it has become clear that their intracellular functions result
from intricate biochemical networks of the GTPase and their regulators that dynamically
bind to a membrane surface. Due to the inherent complexities of their interactions,
however, revealing the underlying mechanisms of action is often difficult to achieve
from in vivo studies. This review summarizes in vitro reconstitution approaches
developed to obtain a better mechanistic understanding of how small GTPase activities
are regulated in space and time.

text: 'A shared-memory counter is a widely-used and well-studied concurrent object.
It supports two operations: An Inc operation that increases its value by 1 and
a Read operation that returns its current value. In Jayanti et al (SIAM J Comput,
30(2), 2000), Jayanti, Tan and Toueg proved a linear lower bound on the worst-case
step complexity of obstruction-free implementations, from read-write registers,
of a large class of shared objects that includes counters. The lower bound leaves
open the question of finding counter implementations with sub-linear amortized
step complexity. In this work, we address this gap. We show that n-process, wait-free
and linearizable counters can be implemented from read-write registers with O(log2n)
amortized step complexity. This is the first counter algorithm from read-write
registers that provides sub-linear amortized step complexity in executions of
arbitrary length. Since a logarithmic lower bound on the amortized step complexity
of obstruction-free counter implementations exists, our upper bound is within
a logarithmic factor of the optimal. The worst-case step complexity of the construction
remains linear, which is optimal. This is obtained thanks to a new max register
construction with O(logn) amortized step complexity in executions of arbitrary
length in which the value stored in the register does not grow too quickly. We
then leverage an existing counter algorithm by Aspnes, Attiya and Censor-Hillel
[1] in which we “plug” our max register implementation to show that it remains
linearizable while achieving O(log2n) amortized step complexity.'

text: In industrial reactors and equipment, non-ideality is quite a common phenomenon
rather than an exception. These deviations from ideality impact the process's
overall efficiency and the effectiveness of the equipment. To recognize the associated
non-ideality, one needs to have enough understanding of the formulation of the
equations and in-depth knowledge of the residence time distribution (RTD) data
of real reactors. In the current work, step input and pulse input were used to
create RTD data for Cascade continuous stirred tank reactors (CSTRs). For the
aforementioned configuration, experiments were run at various flow rates to validate
the developed characteristic equations. To produce RTD data, distilled water was
utilized as the flowing fluid, and NaOH was the tracer substance. The ideal behavior
of tracer concentration exits age distribution, and cumulative fraction for each
setup and each input was plotted and experimental results were compared with perfect
behavior. Deviation of concentration exit age distribution and cumulative fractional
distribution from ideal behavior is more in pulse input as compared to a step
input. For ideal cases, the exit age distribution curve and cumulative fraction
curves are independent of the type of input. But a significant difference was
observed for the two cases, which may be due to non-measurable fluctuations in
volumetric flow rate, non-achievement of instant injection of tracer in case of
pulse input, and slight variations in the sampling period. Further, with increasing
flow rate, concentration, exit age, and cumulative fractional curves shifted upward,
and this behavior matches with the actual case.

text: "Introduction: The olfactory system in most mammals is divided into several
subsystems based on the anatomical locations of the neuroreceptor cells involved
and the receptor families that are expressed. In addition to the main olfactory
system and the vomeronasal system, a range of olfactory subsystems converge onto
the transition zone located between the main olfactory bulb (MOB) and the accessory
olfactory bulb (AOB), which has been termed the olfactory limbus (OL). The OL
contains specialized glomeruli that receive noncanonical sensory afferences and
which interact with the MOB and AOB. Little is known regarding the olfactory subsystems
of mammals other than laboratory rodents.\r\nMethods: We have focused on characterizing
the OL in the red fox by performing general and specific histological stainings
on serial sections, using both single and double immunohistochemical and lectin-histochemical
labeling techniques.\r\nResults: As a result, we have been able to determine that
the OL of the red fox (Vulpes vulpes) displays an uncommonly high degree of development
and complexity.\r\nDiscussion: This makes this species a novel mammalian model,
the study of which could improve our understanding of the noncanonical pathways
involved in the processing of chemosensory cues."

text: Regulation of chromatin states involves the dynamic interplay between different
histone modifications to control gene expression. Recent advances have enabled
mapping of histone marks in single cells, but most methods are constrained to
profile only one histone mark per cell. Here, we present an integrated experimental
and computational framework, scChIX-seq (single-cell chromatin immunocleavage
and unmixing sequencing), to map several histone marks in single cells. scChIX-seq
multiplexes two histone marks together in single cells, then computationally deconvolves
the signal using training data from respective histone mark profiles. This framework
learns the cell-type-specific correlation structure between histone marks, and
therefore does not require a priori assumptions of their genomic distributions.
Using scChIX-seq, we demonstrate multimodal analysis of histone marks in single
cells across a range of mark combinations. Modeling dynamics of in vitro macrophage
differentiation enables integrated analysis of chromatin velocity. Overall, scChIX-seq
unlocks systematic interrogation of the interplay between histone modifications
in single cells.

text: We consider a gas of n bosonic particles confined in a box [−ℓ/2,ℓ/2]3 with
Neumann boundary conditions. We prove Bose–Einstein condensation in the Gross–Pitaevskii
regime, with an optimal bound on the condensate depletion. Moreover, our lower
bound for the ground state energy in a small box [−ℓ/2,ℓ/2]3 implies (via Neumann
bracketing) a lower bound for the ground state energy of N bosons in a large box
[−L/2,L/2]3 with density ρ=N/L3 in the thermodynamic limit.

text: Geometry is crucial in our efforts to comprehend the structures and dynamics
of biomolecules. For example, volume, surface area, and integrated mean and Gaussian
curvature of the union of balls representing a molecule are used to quantify its
interactions with the water surrounding it in the morphometric implicit solvent
models. The Alpha Shape theory provides an accurate and reliable method for computing
these geometric measures. In this paper, we derive homogeneous formulas for the
expressions of these measures and their derivatives with respect to the atomic
coordinates, and we provide algorithms that implement them into a new software
package, AlphaMol. The only variables in these formulas are the interatomic distances,
making them insensitive to translations and rotations. AlphaMol includes a sequential
algorithm and a parallel algorithm. In the parallel version, we partition the
atoms of the molecule of interest into 3D rectangular blocks, using a kd-tree
algorithm. We then apply the sequential algorithm of AlphaMol to each block, augmented
by a buffer zone to account for atoms whose ball representations may partially
cover the block. The current parallel version of AlphaMol leads to a 20-fold speed-up
compared to an independent serial implementation when using 32 processors. For
instance, it takes 31 s to compute the geometric measures and derivatives of each
atom in a viral capsid with more than 26 million atoms on 32 Intel processors
running at 2.7 GHz. The presence of the buffer zones, however, leads to redundant
computations, which ultimately limit the impact of using multiple processors.
AlphaMol is available as an OpenSource software.

text: Treating sick group members is a hallmark of collective disease defence in
vertebrates and invertebrates alike. Despite substantial effects on pathogen fitness
and epidemiology, it is still largely unknown how pathogens react to the selection
pressure imposed by care intervention. Using social insects and pathogenic fungi,
we here performed a serial passage experiment in the presence or absence of colony
members, which provide social immunity by grooming off infectious spores from
exposed individuals. We found specific effects on pathogen diversity, virulence
and transmission. Under selection of social immunity, pathogens invested into
higher spore production, but spores were less virulent. Notably, they also elicited
a lower grooming response in colony members, compared with spores from the individual
host selection lines. Chemical spore analysis suggested that the spores from social
selection lines escaped the caregivers’ detection by containing lower levels of
ergosterol, a key fungal membrane component. Experimental application of chemically
pure ergosterol indeed induced sanitary grooming, supporting its role as a microbe-associated
cue triggering host social immunity against fungal pathogens. By reducing this
detection cue, pathogens were able to evade the otherwise very effective collective
disease defences of their social hosts.

text: Differentiated X chromosomes are expected to have higher rates of adaptive
divergence than autosomes, if new beneficial mutations are recessive (the “faster-X
effect”), largely because these mutations are immediately exposed to selection
in males. The evolution of X chromosomes after they stop recombining in males,
but before they become hemizygous, has not been well explored theoretically. We
use the diffusion approximation to infer substitution rates of beneficial and
deleterious mutations under such a scenario. Our results show that selection is
less efficient on diploid X loci than on autosomal and hemizygous X loci under
a wide range of parameters. This “slower-X” effect is stronger for genes affecting
primarily (or only) male fitness, and for sexually antagonistic genes. These unusual
dynamics suggest that some of the peculiar features of X chromosomes, such as
the differential accumulation of genes with sex-specific functions, may start
arising earlier than previously appreciated.

text: How to generate a brain of correct size and with appropriate cell-type diversity
during development is a major question in Neuroscience. In the developing neocortex,
radial glial progenitor (RGP) cells are the main neural stem cells that produce
cortical excitatory projection neurons, glial cells, and establish the prospective
postnatal stem cell niche in the lateral ventricles. RGPs follow a tightly orchestrated
developmental program that when disrupted can result in severe cortical malformations
such as microcephaly and megalencephaly. The precise cellular and molecular mechanisms
instructing faithful RGP lineage progression are however not well understood.
This review will summarize recent conceptual advances that contribute to our understanding
of the general principles of RGP lineage progression.

text: In this paper, we consider traces at initial times for functions with mixed
time-space smoothness. Such results are often needed in the theory of evolution
equations. Our result extends and unifies many previous results. Our main improvement
is that we can allow general interpolation couples. The abstract results are applied
to regularity problems for fractional evolution equations and stochastic evolution
equations, where uniform trace estimates on the half-line are shown.

text: We study the time evolution of the Nelson model in a mean-field limit in which
N nonrelativistic bosons weakly couple (with respect to the particle number) to
a positive or zero mass quantized scalar field. Our main result is the derivation
of the Bogoliubov dynamics and higher-order corrections. More precisely, we prove
the convergence of the approximate wave function to the many-body wave function
in norm, with a convergence rate proportional to the number of corrections taken
into account in the approximation. We prove an analogous result for the unitary
propagator. As an application, we derive a simple system of partial differential
equations describing the time evolution of the first- and second-order approximations
to the one-particle reduced density matrices of the particles and the quantum
field, respectively.

text: Neurons in the brain are wired into adaptive networks that exhibit collective
dynamics as diverse as scale-specific oscillations and scale-free neuronal avalanches.
Although existing models account for oscillations and avalanches separately, they
typically do not explain both phenomena, are too complex to analyze analytically
or intractable to infer from data rigorously. Here we propose a feedback-driven
Ising-like class of neural networks that captures avalanches and oscillations
simultaneously and quantitatively. In the simplest yet fully microscopic model
version, we can analytically compute the phase diagram and make direct contact
with human brain resting-state activity recordings via tractable inference of
the model’s two essential parameters. The inferred model quantitatively captures
the dynamics over a broad range of scales, from single sensor oscillations to
collective behaviors of extreme events and neuronal avalanches. Importantly, the
inferred parameters indicate that the co-existence of scale-specific (oscillations)
and scale-free (avalanches) dynamics occurs close to a non-equilibrium critical
point at the onset of self-sustained oscillations.

text: "The tight spatiotemporal coordination of signaling activity determining embryo\r\npatterning
and the physical processes driving embryo morphogenesis renders\r\nembryonic development
robust, such that key developmental processes can unfold\r\nrelatively normally
even outside of the full embryonic context. For instance, embryonic\r\nstem cell
cultures can recapitulate the hallmarks of gastrulation, i.e. break symmetry\r\nleading
to germ layer formation and morphogenesis, in a very reduced environment.\r\nThis
leads to questions on specific contributions of embryo-specific features, such
as\r\nthe presence of extraembryonic tissues, which are inherently involved in
gastrulation\r\nin the full embryonic context. To address this, we established
zebrafish embryonic\r\nexplants without the extraembryonic yolk cell, an important
player as a signaling\r\nsource and for morphogenesis during gastrulation, as
a model of ex vivo development.\r\nWe found that dorsal-marginal determinants
are required and sufficient in these\r\nexplants to form and pattern all three
germ layers. However, formation of tissues,\r\nwhich require the highest Nodal-signaling
levels, is variable, demonstrating a\r\ncontribution of extraembryonic tissues
for reaching peak Nodal signaling levels.\r\nBlastoderm explants also undergo
gastrulation-like axis elongation. We found that this\r\nelongation movement shows
hallmarks of oriented mesendoderm cell intercalations\r\ntypically associated
with dorsal tissues in the intact embryo. These are disrupted by\r\nuniform upregulation
of BMP signaling activity and concomitant explant ventralization,\r\nsuggesting
that tight spatial control of BMP signaling is a prerequisite for explant\r\nmorphogenesis.
This control is achieved by Nodal signaling, which is critical for\r\neffectively
downregulating BMP signaling in the mesendoderm, highlighting that Nodal\r\nsignaling
is not only directly required for mesendoderm cell fate specification and\r\nmorphogenesis,
but also by maintaining low levels of BMP signaling at the dorsal side.\r\nCollectively,
we provide insights into the capacity and organization of signaling and\r\nmorphogenetic
domains to recapitulate features of zebrafish gastrulation outside of\r\nthe full
embryonic context."

text: "A central problem in computational statistics is to convert a procedure for
sampling combinatorial objects into a procedure for counting those objects, and
vice versa. We will consider sampling problems which come from Gibbs distributions,
which are families of probability distributions over a discrete space Ω with probability
mass function of the form μ^Ω_β(ω) ∝ e^{β H(ω)} for β in an interval [β_min, β_max]
and H(ω) ∈ {0} ∪ [1, n].\r\nThe partition function is the normalization factor
Z(β) = ∑_{ω ∈ Ω} e^{β H(ω)}, and the log partition ratio is defined as q = (log
Z(β_max))/Z(β_min)\r\nWe develop a number of algorithms to estimate the counts
c_x using roughly Õ(q/ε²) samples for general Gibbs distributions and Õ(n²/ε²)
samples for integer-valued distributions (ignoring some second-order terms and
parameters), We show this is optimal up to logarithmic factors. We illustrate
with improved algorithms for counting connected subgraphs and perfect matchings
in a graph."
acknowledgement: We thank Heng Guo for helpful explanations of algorithms for sampling
connected subgraphs and matchings, Maksym Serbyn for bringing to our attention the
Wang-Landau algorithm and its use in physics.

text: "The maximization of submodular functions have found widespread application
in areas such as machine learning, combinatorial optimization, and economics,
where practitioners often wish to enforce various constraints; the matroid constraint
has been investigated extensively due to its algorithmic properties and expressive
power. Though tight approximation algorithms for general matroid constraints exist
in theory, the running times of such algorithms typically scale quadratically,
and are not practical for truly large scale settings. Recent progress has focused
on fast algorithms for important classes of matroids given in explicit form. Currently,
nearly-linear time algorithms only exist for graphic and partition matroids [Alina
Ene and Huy L. Nguyen, 2019]. In this work, we develop algorithms for monotone
submodular maximization constrained by graphic, transversal matroids, or laminar
matroids in time near-linear in the size of their representation. Our algorithms
achieve an optimal approximation of 1-1/e-ε and both generalize and accelerate
the results of Ene and Nguyen [Alina Ene and Huy L. Nguyen, 2019]. In fact, the
running time of our algorithm cannot be improved within the fast continuous greedy
framework of Badanidiyuru and Vondrák [Ashwinkumar Badanidiyuru and Jan Vondrák,
2014].\r\nTo achieve near-linear running time, we make use of dynamic data structures
that maintain bases with approximate maximum cardinality and weight under certain
element updates. These data structures need to support a weight decrease operation
and a novel Freeze operation that allows the algorithm to freeze elements (i.e.
force to be contained) in its basis regardless of future data structure operations.
For the laminar matroid, we present a new dynamic data structure using the top
tree interface of Alstrup, Holm, de Lichtenberg, and Thorup [Stephen Alstrup et
al., 2005] that maintains the maximum weight basis under insertions and deletions
of elements in O(log n) time. This data structure needs to support certain subtree
query and path update operations that are performed every insertion and deletion
that are non-trivial to handle in conjunction. For the transversal matroid the
Freeze operation corresponds to requiring the data structure to keep a certain
set S of vertices matched, a property that we call S-stability. While there is
a large body of work on dynamic matching algorithms, none are S-stable and maintain
an approximate maximum weight matching under vertex updates. We give the first
such algorithm for bipartite graphs with total running time linear (up to log
factors) in the number of edges."

text: "In this work we consider the list-decodability and list-recoverability of
arbitrary q-ary codes, for all integer values of q ≥ 2. A code is called (p,L)_q-list-decodable
if every radius pn Hamming ball contains less than L codewords; (p,\U0001D4C1,L)_q-list-recoverability
is a generalization where we place radius pn Hamming balls on every point of a
combinatorial rectangle with side length \U0001D4C1 and again stipulate that there
be less than L codewords.\r\nOur main contribution is to precisely calculate the
maximum value of p for which there exist infinite families of positive rate (p,\U0001D4C1,L)_q-list-recoverable
codes, the quantity we call the zero-rate threshold. Denoting this value by p_*,
we in fact show that codes correcting a p_*+ε fraction of errors must have size
O_ε(1), i.e., independent of n. Such a result is typically referred to as a \"Plotkin
bound.\" To complement this, a standard random code with expurgation construction
shows that there exist positive rate codes correcting a p_*-ε fraction of errors.
We also follow a classical proof template (typically attributed to Elias and Bassalygo)
to derive from the zero-rate threshold other tradeoffs between rate and decoding
radius for list-decoding and list-recovery.\r\nTechnically, proving the Plotkin
bound boils down to demonstrating the Schur convexity of a certain function defined
on the q-simplex as well as the convexity of a univariate function derived from
it. We remark that an earlier argument claimed similar results for q-ary list-decoding;
however, we point out that this earlier proof is flawed."

text: The influence of structural modifications on the catalytic activity of carbon
materials is poorly understood. A collection of carbonaceous materials with different
pore networks and high nitrogen content was characterized and used to catalyze
four reactions to deduce structure–activity relationships. The CO2 cycloaddition
and Knoevenagel reaction depend on Lewis basic sites (electron-rich nitrogen species).
The absence of large conjugated carbon domains resulting from the introduction
of large amounts of nitrogen in the carbon network is responsible for poor redox
activity, as observed through the catalytic reduction of nitrobenzene with hydrazine
and the catalytic oxidation of 3,3′,5,5′-tetramethylbenzidine using hydroperoxide.
The material with the highest activity towards Lewis acid catalysis (in the hydrolysis
of (dimethoxymethyl)benzene to benzaldehyde) is the most effective for small molecule
activation and presents the highest concentration of electron-poor nitrogen species.

text: In previous work, we identified a population of 38 cool and luminous variable
stars in the Magellanic Clouds and examined 11 in detail in order to classify
them as either Thorne–Żytkow objects (TŻOs; red supergiants with a neutron star
cores) or super-asymptotic giant branch (sAGB) stars (the most massive stars that
will not undergo core collapse). This population includes HV 2112, a peculiar
star previously considered in other works to be either a TŻO or high-mass asymptotic
giant branch (AGB) star. Here we continue this investigation, using the kinematic
and radio environments and local star formation history of these stars to place
constraints on the age of the progenitor systems and the presence of past supernovae.
These stars are not associated with regions of recent star formation, and we find
no evidence of past supernovae at their locations. Finally, we also assess the
presence of heavy elements and lithium in their spectra compared to red supergiants.
We find strong absorption in Li and s-process elements compared to RSGs in most
of the sample, consistent with sAGB nucleosynthesis, while HV 2112 shows additional
strong lines associated with TŻO nucleosynthesis. Coupled with our previous mass
estimates, the results are consistent with the stars being massive (∼4–6.5 M⊙)
or sAGB (∼6.5–12 M⊙) stars in the thermally pulsing phase, providing crucial observations
of the transition between low- and high-mass stellar populations. HV 2112 is more
ambiguous; it could either be a maximally massive sAGB star, or a TŻO if the minimum
mass for stability extends down to ≲13 M⊙.

text: Stars strongly impact their environment, and shape structures on all scales
throughout the universe, in a process known as "feedback." Due to the complexity
of both stellar evolution and the physics of larger astrophysical structures,
there remain many unanswered questions about how feedback operates and what we
can learn about stars by studying their imprint on the wider universe. In this
white paper, we summarize discussions from the Lorentz Center meeting "Bringing
Stellar Evolution and Feedback Together" in 2022 April and identify key areas
where further dialog can bring about radical changes in how we view the relationship
between stars and the universe they live in.

text: 'Thorne–Żytkow objects (TŻO) are potential end products of the merger of a
neutron star with a non-degenerate star. In this work, we have computed the first
grid of evolutionary models of TŻOs with the MESA stellar evolution code. With
these models, we predict several observational properties of TŻOs, including their
surface temperatures and luminosities, pulsation periods, and nucleosynthetic
products. We expand the range of possible TŻO solutions to cover 3.45≲log(Teff/K)≲3.65
and 4.85≲log(L/L⊙)≲5.5. Due to the much higher densities our TŻOs reach compared
to previous models, if TŻOs form we expect them to be stable over a larger mass
range than previously predicted, without exhibiting a gap in their mass distribution.
Using the GYRE stellar pulsation code we show that TŻOs should have fundamental
pulsation periods of 1000–2000 d, and period ratios of ≈0.2–0.3. Models computed
with a large 399 isotope fully coupled nuclear network show a nucleosynthetic
signal that is different to previously predicted. We propose a new nucleosynthetic
signal to determine a star’s status as a TŻO: the isotopologues 44TiO2 and 44TiO,
which will have a shift in their spectral features as compared to stable titanium-containing
molecules. We find that in the local Universe (∼SMC metallicities and above) TŻOs
show little heavy metal enrichment, potentially explaining the difficulty in finding
TŻOs to-date.'

text: Characterizing and controlling entanglement in quantum materials is crucial
for the development of next-generation quantum technologies. However, defining
a quantifiable figure of merit for entanglement in macroscopic solids is theoretically
and experimentally challenging. At equilibrium the presence of entanglement can
be diagnosed by extracting entanglement witnesses from spectroscopic observables
and a nonequilibrium extension of this method could lead to the discovery of novel
dynamical phenomena. Here, we propose a systematic approach to quantify the time-dependent
quantum Fisher information and entanglement depth of transient states of quantum
materials with time-resolved resonant inelastic x-ray scattering. Using a quarter-filled
extended Hubbard model as an example, we benchmark the efficiency of this approach
and predict a light-enhanced many-body entanglement due to the proximity to a
phase boundary. Our work sets the stage for experimentally witnessing and controlling
entanglement in light-driven quantum materials via ultrafast spectroscopic measurements.

text: Many-body entanglement in condensed matter systems can be diagnosed from equilibrium
response functions through the use of entanglement witnesses and operator-specific
quantum bounds. Here, we investigate the applicability of this approach for detecting
entangled states in quantum systems driven out of equilibrium. We use a multipartite
entanglement witness, the quantum Fisher information, to study the dynamics of
a paradigmatic fermion chain undergoing a time-dependent change of the Coulomb
interaction. Our results show that the quantum Fisher information is able to witness
distinct signatures of multipartite entanglement both near and far from equilibrium
that are robust against decoherence. We discuss implications of these findings
for probing entanglement in light-driven quantum materials with time-resolved
optical and x-ray scattering methods.

text: Models for same-material contact electrification in granular media often rely
on a local charge-driving parameter whose spatial variations lead to a stochastic
origin for charge exchange. Measuring the charge transfer from individual granular
spheres after contacts with substrates of the same material, we find instead a
“global” charging behavior, coherent over the sample’s whole surface. Cleaning
and baking samples fully resets charging magnitude and direction, which indicates
the underlying global parameter is not intrinsic to the material, but acquired
from its history. Charging behavior is randomly and irreversibly affected by changes
in relative humidity, hinting at a mechanism where adsorbates, in particular,
water, are fundamental to the charge-transfer process.

text: Observations of individual massive stars, super-luminous supernovae, gamma-ray
bursts, and gravitational wave events involving spectacular black hole mergers
indicate that the low-metallicity Universe is fundamentally different from our
own Galaxy. Many transient phenomena will remain enigmatic until we achieve a
firm understanding of the physics and evolution of massive stars at low metallicity
(Z). The Hubble Space Telescope has devoted 500 orbits to observing ∼250 massive
stars at low Z in the ultraviolet (UV) with the COS and STIS spectrographs under
the ULLYSES programme. The complementary X-Shooting ULLYSES (XShootU) project
provides an enhanced legacy value with high-quality optical and near-infrared
spectra obtained with the wide-wavelength coverage X-shooter spectrograph at ESO’s
Very Large Telescope. We present an overview of the XShootU project, showing that
combining ULLYSES UV and XShootU optical spectra is critical for the uniform determination
of stellar parameters such as effective temperature, surface gravity, luminosity,
and abundances, as well as wind properties such as mass-loss rates as a function
of Z. As uncertainties in stellar and wind parameters percolate into many adjacent
areas of astrophysics, the data and modelling of the XShootU project is expected
to be a game changer for our physical understanding of massive stars at low Z.
To be able to confidently interpret James Webb Space Telescope spectra of the
first stellar generations, the individual spectra of low-Z stars need to be understood,
which is exactly where XShootU can deliver.

text: "About a 100 years ago, we discovered that our universe is inherently noisy,
that is, measuring any physical quantity with a precision beyond a certain point
is not possible because of an omnipresent inherent noise. We call this - the quantum
noise. Certain physical processes allow this quantum noise to get correlated in
conjugate physical variables. These quantum correlations can be used to go beyond
the potential of our inherently noisy universe and obtain a quantum advantage
over the classical applications. \r\n\r\nQuantum noise being inherent also means
that, at the fundamental level, the physical quantities are not well defined and
therefore, objects can stay in multiple states at the same time. For example,
the position of a particle not being well defined means that the particle is in
multiple positions at the same time. About 4 decades ago, we started exploring
the possibility of using objects which can be in multiple states at the same time
to increase the dimensionality in computation. Thus, the field of quantum computing
was born. We discovered that using quantum entanglement, a property closely related
to quantum correlations, can be used to speed up computation of certain problems,
such as factorisation of large numbers, faster than any known classical algorithm.
Thus began the pursuit to make quantum computers a reality. \r\n\r\nTill date,
we have explored quantum control over many physical systems including photons,
spins, atoms, ions and even simple circuits made up of superconducting material.
However, there persists one ubiquitous theme. The more readily a system interacts
with an external field or matter, the more easily we can control it. But this
also means that such a system can easily interact with a noisy environment and
quickly lose its coherence. Consequently, such systems like electron spins need
to be protected from the environment to ensure the longevity of their coherence.
Other systems like nuclear spins are naturally protected as they do not interact
easily with the environment. But, due to the same reason, it is harder to interact
with such systems. \r\n\r\nAfter decades of experimentation with various systems,
we are convinced that no one type of quantum system would be the best for all
the quantum applications. We would need hybrid systems which are all interconnected
- much like the current internet where all sorts of devices can all talk to each

are the best contenders to carry information for the quantum internet. They can
carry quantum information cheaply and without much loss - the same reasons which
has made them the backbone of our current internet. Following this direction,
many systems, like trapped ions, have already demonstrated successful quantum
links over a large distances using optical photons. However, some of the most
promising contenders for quantum computing which are based on microwave frequencies
have been left behind. This is because high energy optical photons can adversely
affect fragile low-energy microwave systems. \r\n\r\nIn this thesis, we present
substantial progress on this missing quantum link between microwave and optics
using electrooptical nonlinearities in lithium niobate. The nonlinearities are
enhanced by using resonant cavities for all the involved modes leading to observation
of strong direct coupling between optical and microwave frequencies. With this
strong coupling we are not only able to achieve almost 100\\% internal conversion
efficiency with low added noise, thus presenting a quantum-enabled transducer,
but also we are able to observe novel effects such as cooling of a microwave mode
using optics. The strong coupling regime also leads to direct observation of dynamical
backaction effect between microwave and optical frequencies which are studied
in detail here. Finally, we also report first observation of microwave-optics
entanglement in form of two-mode squeezed vacuum squeezed 0.7dB below vacuum level.
\r\nWith this new bridge between microwave and optics, the microwave-based quantum
technologies can finally be a part of a quantum network which is based on optical
photons - putting us one step closer to a future with quantum internet. "

text: "About a 100 years ago, we discovered that our universe is inherently noisy,
that is, measuring any physical quantity with a precision beyond a certain point
is not possible because of an omnipresent inherent noise. We call this - the quantum
noise. Certain physical processes allow this quantum noise to get correlated in
conjugate physical variables. These quantum correlations can be used to go beyond
the potential of our inherently noisy universe and obtain a quantum advantage
over the classical applications. \r\n\r\nQuantum noise being inherent also means
that, at the fundamental level, the physical quantities are not well defined and
therefore, objects can stay in multiple states at the same time. For example,
the position of a particle not being well defined means that the particle is in
multiple positions at the same time. About 4 decades ago, we started exploring
the possibility of using objects which can be in multiple states at the same time
to increase the dimensionality in computation. Thus, the field of quantum computing
was born. We discovered that using quantum entanglement, a property closely related
to quantum correlations, can be used to speed up computation of certain problems,
such as factorisation of large numbers, faster than any known classical algorithm.
Thus began the pursuit to make quantum computers a reality. \r\n\r\nTill date,
we have explored quantum control over many physical systems including photons,
spins, atoms, ions and even simple circuits made up of superconducting material.
However, there persists one ubiquitous theme. The more readily a system interacts
with an external field or matter, the more easily we can control it. But this
also means that such a system can easily interact with a noisy environment and
quickly lose its coherence. Consequently, such systems like electron spins need
to be protected from the environment to ensure the longevity of their coherence.
Other systems like nuclear spins are naturally protected as they do not interact
easily with the environment. But, due to the same reason, it is harder to interact
with such systems. \r\n\r\nAfter decades of experimentation with various systems,
we are convinced that no one type of quantum system would be the best for all
the quantum applications. We would need hybrid systems which are all interconnected
- much like the current internet where all sorts of devices can all talk to each

text: We study the problem of training and certifying adversarially robust quantized
neural networks (QNNs). Quantization is a technique for making neural networks
more efficient by running them using low-bit integer arithmetic and is therefore
commonly adopted in industry. Recent work has shown that floating-point neural
networks that have been verified to be robust can become vulnerable to adversarial
attacks after quantization, and certification of the quantized representation
is necessary to guarantee robustness. In this work, we present quantization-aware
interval bound propagation (QA-IBP), a novel method for training robust QNNs.
Inspired by advances in robust learning of non-quantized networks, our training
algorithm computes the gradient of an abstract representation of the actual network.
Unlike existing approaches, our method can handle the discrete semantics of QNNs.
Based on QA-IBP, we also develop a complete verification procedure for verifying
the adversarial robustness of QNNs, which is guaranteed to terminate and produce
a correct answer. Compared to existing approaches, the key advantage of our verification
procedure is that it runs entirely on GPU or other accelerator devices. We demonstrate
experimentally that our approach significantly outperforms existing methods and
establish the new state-of-the-art for training and certifying the robustness
of QNNs.

text: 'Two-player zero-sum "graph games" are central in logic, verification, and
multi-agent systems. The game proceeds by placing a token on a vertex of a graph,
and allowing the players to move it to produce an infinite path, which determines
the winner or payoff of the game. Traditionally, the players alternate turns in
moving the token. In "bidding games", however, the players have budgets and in
each turn, an auction (bidding) determines which player moves the token. So far,
bidding games have only been studied as full-information games. In this work we
initiate the study of partial-information bidding games: we study bidding games
in which a player''s initial budget is drawn from a known probability distribution.
We show that while for some bidding mechanisms and objectives, it is straightforward
to adapt the results from the full-information setting to the partial-information
setting, for others, the analysis is significantly more challenging, requires
new techniques, and gives rise to interesting results. Specifically, we study
games with "mean-payoff" objectives in combination with "poorman" bidding. We
construct optimal strategies for a partially-informed player who plays against
a fully-informed adversary. We show that, somewhat surprisingly, the "value" under
pure strategies does not necessarily exist in such games.'

text: We present a technique to optimize the reflectivity of a surface while preserving
its overall shape. The naïve optimization of the mesh vertices using the gradients
of reflectivity simulations results in undesirable distortion. In contrast, our
robust formulation optimizes the surface normal as an independent variable that
bridges the reflectivity term with differential rendering, and the regularization
term with as-rigid-as-possible elastic energy. We further adaptively subdivide
the input mesh to improve the convergence. Consequently, our method can minimize
the retroreflectivity of a wide range of input shapes, resulting in sharply creased
shapes ubiquitous among stealth aircraft and Sci-Fi vehicles. Furthermore, by
changing the reward for the direction of the outgoing light directions, our method
can be applied to other reflectivity design tasks, such as the optimization of
architectural walls to concentrate light in a specific region. We have tested
the proposed method using light-transport simulations and real-world 3D-printed
objects.

text: Presynaptic inputs determine the pattern of activation of postsynaptic neurons
in a neural circuit. Molecular and genetic pathways that regulate the selective
formation of subsets of presynaptic inputs are largely unknown, despite significant
understanding of the general process of synaptogenesis. In this study, we have
begun to identify such factors using the spinal monosynaptic stretch reflex circuit
as a model system. In this neuronal circuit, Ia proprioceptive afferents establish
monosynaptic connections with spinal motor neurons that project to the same muscle
(termed homonymous connections) or muscles with related or synergistic function.
However, monosynaptic connections are not formed with motor neurons innervating
muscles with antagonistic functions. The ETS transcription factor ER81 (also known
as ETV1) is expressed by all proprioceptive afferents, but only a small set of
motor neuron pools in the lumbar spinal cord of the mouse. Here we use conditional
mouse genetic techniques to eliminate Er81 expression selectively from motor neurons.
We find that ablation of Er81 in motor neurons reduces synaptic inputs from proprioceptive
afferents conveying information from homonymous and synergistic muscles, with
no change observed in the connectivity pattern from antagonistic proprioceptive
afferents. In summary, these findings suggest a role for ER81 in defined motor
neuron pools to control the assembly of specific presynaptic inputs and thereby
influence the profile of activation of these motor neurons.

text: Machine-learned systems are in widespread use for making decisions about humans,
and it is important that they are fair, i.e., not biased against individuals based
on sensitive attributes. We present runtime verification of algorithmic fairness
for systems whose models are unknown, but are assumed to have a Markov chain structure.
We introduce a specification language that can model many common algorithmic fairness
properties, such as demographic parity, equal opportunity, and social burden.
We build monitors that observe a long sequence of events as generated by a given
system, and output, after each observation, a quantitative estimate of how fair
or biased the system was on that run until that point in time. The estimate is
proven to be correct modulo a variable error bound and a given confidence level,
where the error bound gets tighter as the observed sequence gets longer. Our monitors
are of two types, and use, respectively, frequentist and Bayesian statistical
inference techniques. While the frequentist monitors compute estimates that are
objectively correct with respect to the ground truth, the Bayesian monitors compute
estimates that are correct subject to a given prior belief about the system’s
model. Using a prototype implementation, we show how we can monitor if a bank
is fair in giving loans to applicants from different social backgrounds, and if
a college is fair in admitting students while maintaining a reasonable financial
burden on the society. Although they exhibit different theoretical complexities
in certain cases, in our experiments, both frequentist and Bayesian monitors took
less than a millisecond to update their verdicts after each observation.

text: "Background: This study seeks to evaluate the impact of breast cancer (BRCA)
gene status on tumor dissemination pattern, surgical outcome and survival in a
multicenter cohort of paired primary ovarian cancer (pOC) and recurrent ovarian
cancer (rOC).\r\n\r\nPatients and Methods: Medical records and follow-up data
from 190 patients were gathered retrospectively. All patients had surgery at pOC
and at least one further rOC surgery at four European high-volume centers. Patients
were divided into one cohort with confirmed mutation for BRCA1 and/or BRCA2 (BRCAmut)
and a second cohort with BRCA wild type or unknown (BRCAwt). Patterns of tumor
presentation, surgical outcome and survival data were analyzed between the two
groups.\r\n\r\nResults: Patients with BRCAmut disease were on average 4 years
younger and had significantly more tumor involvement upon diagnosis. Patients
with BRCAmut disease showed higher debulking rates at all stages. Multivariate
analysis showed that only patient age had significant predictive value for complete
tumor resection in pOC. At rOC, however, only BRCAmut status significantly correlated
with optimal debulking. Patients with BRCAmut disease showed significantly prolonged
overall survival (OS) by 24.3 months. Progression-free survival (PFS) was prolonged
in the BRCAmut group at all stages as well, reaching statistical significance
during recurrence.\r\n\r\nConclusions: Patients with BRCAmut disease showed a
more aggressive course of disease with earlier onset and more extensive tumor
dissemination at pOC. However, surgical outcome and OS were significantly better
in patients with BRCAmut disease compared with patients with BRCAwt disease. We
therefore propose to consider BRCAmut status in regard to patient selection for
cytoreductive surgery, especially in rOC."

text: Junctions between the endoplasmic reticulum (ER) and the plasma membrane (PM)
are specialized membrane contacts ubiquitous in eukaryotic cells. Concentration
of intracellular signaling machinery near ER-PM junctions allows these domains
to serve critical roles in lipid and Ca2+ signaling and homeostasis. Subcellular
compartmentalization of protein kinase A (PKA) signaling also regulates essential
cellular functions, however, no specific association between PKA and ER-PM junctional
domains is known. Here, we show that in brain neurons type I PKA is directed to
Kv2.1 channel-dependent ER-PM junctional domains via SPHKAP, a type I PKA-specific
anchoring protein. SPHKAP association with type I PKA regulatory subunit RI and
ER-resident VAP proteins results in the concentration of type I PKA between stacked
ER cisternae associated with ER-PM junctions. This ER-associated PKA signalosome
enables reciprocal regulation between PKA and Ca2+ signaling machinery to support
Ca2+ influx and excitation-transcription coupling. These data reveal that neuronal
ER-PM junctions support a receptor-independent form of PKA signaling driven by
membrane depolarization and intracellular Ca2+, allowing conversion of information
encoded in electrical signals into biochemical changes universally recognized
throughout the cell.

text: "We provide a learning-based technique for guessing a winning strategy in
a parity game originating from an LTL synthesis problem. A cheaply obtained guess
can be useful in several applications. Not only can the guessed strategy be applied
as best-effort in cases where the game’s huge size prohibits rigorous approaches,
but it can also increase the scalability of rigorous LTL synthesis in several
ways. Firstly, checking whether a guessed strategy is winning is easier than constructing
one. Secondly, even if the guess is wrong in some places, it can be fixed by strategy
iteration faster than constructing one from scratch. Thirdly, the guess can be
used in on-the-fly approaches to prioritize exploration in the most fruitful directions.\r\nIn
contrast to previous works, we (i) reflect the highly structured logical information
in game’s states, the so-called semantic labelling, coming from the recent LTL-to-automata
translations, and (ii) learn to reflect it properly by learning from previously
solved games, bringing the solving process closer to human-like reasoning."

text: "Despite their recent success, deep neural networks continue to perform poorly
when they encounter distribution shifts at test time. Many recently proposed approaches
try to counter this by aligning the model to the new distribution prior to inference.
With no labels available this requires unsupervised objectives to adapt the model
on the observed test data. In this paper, we propose Test-Time SelfTraining (TeST):
a technique that takes as input a model trained on some source data and a novel
data distribution at test time, and learns invariant and robust representations
using a student-teacher framework. We find that models adapted using TeST significantly
improve over baseline testtime adaptation algorithms. TeST achieves competitive
performance to modern domain adaptation algorithms [4, 43], while having access
to 5-10x less data at time of adaption. We thoroughly evaluate a variety of baselines
on two tasks:\r\nobject detection and image segmentation and find that models
adapted with TeST. We find that TeST sets the new stateof-the art for test-time
domain adaptation algorithms. "

text: "Context. Space asteroseismology is revolutionizing our knowledge of the internal
structure and dynamics of stars. A breakthrough is ongoing with the recent discoveries
of signatures of strong magnetic fields in the core of red giant stars. The key
signature for such a detection is the asymmetry these fields induce in the frequency
splittings of observed dipolar mixed gravito-acoustic modes.\r\nAims. We investigate
the ability of the observed asymmetries of the frequency splittings of dipolar
mixed modes to constrain the geometrical properties of deep magnetic fields.\r\nMethods.
We used the powerful analytical Racah-Wigner algebra used in quantum mechanics
to characterize the geometrical couplings of dipolar mixed oscillation modes with
various realistically plausible topologies of fossil magnetic fields. We also
computed the induced perturbation of their frequencies.\r\nResults. First, in
the case of an oblique magnetic dipole, we provide the exact analytical expression
of the asymmetry as a function of the angle between the rotation and magnetic
axes. Its value provides a direct measure of this angle. Second, considering a
combination of axisymmetric dipolar and quadrupolar fields, we show how the asymmetry
is blind to the unraveling of the relative strength and sign of each component.
Finally, in the case of a given multipole, we show that a negative asymmetry is
a signature of non-axisymmetric topologies.\r\nConclusions. Asymmetries of dipolar
mixed modes provide a key bit of information on the geometrical topology of deep
fossil magnetic fields, but this is insufficient on its own. Asteroseismic constraints
should therefore be combined with spectropolarimetric observations and numerical
simulations, which aim to predict the more probable stable large-scale geometries."

text: In this work, a generalized, adapted Numerov implementation capable of determining
band structures of periodic quantum systems is outlined. Based on the input potential,
the presented approach numerically solves the Schrödinger equation in position
space at each momentum space point. Thus, in addition to the band structure, the
method inherently provides information about the state functions and probability
densities in position space at each momentum space point considered. The generalized,
adapted Numerov framework provided reliable estimates for a variety of increasingly
complex test suites in one, two, and three dimensions. The accuracy of the proposed
methodology was benchmarked against results obtained for the analytically solvable
Kronig-Penney model. Furthermore, the presented numerical solver was applied to
a model potential representing a 2D optical lattice being a challenging application
relevant, for example, in the field of quantum computing.

text: This paper focuses on over-parameterized deep neural networks (DNNs) with
ReLU activation functions and proves that when the data distribution is well-separated,
DNNs can achieve Bayes-optimal test error for classification while obtaining (nearly)
zero-training error under the lazy training regime. For this purpose, we unify
three interrelated concepts of overparameterization, benign overfitting, and the
Lipschitz constant of DNNs. Our results indicate that interpolating with smoother
functions leads to better generalization. Furthermore, we investigate the special
case where interpolating smooth ground-truth functions is performed by DNNs under
the Neural Tangent Kernel (NTK) regime for generalization. Our result demonstrates
that the generalization error converges to a constant order that only depends
on label noise and initialization noise, which theoretically verifies benign overfitting.
Our analysis provides a tight lower bound on the normalized margin under non-smooth
activation functions, as well as the minimum eigenvalue of NTK under high-dimensional
settings, which has its own interest in learning theory.

text: Diffusion models excel at generating photorealistic images from text-queries.
Naturally, many approaches have been proposed to use these generative abilities
to augment training datasets for downstream tasks, such as classification. However,
diffusion models are themselves trained on large noisily supervised, but nonetheless,
annotated datasets. It is an open question whether the generalization capabilities
of diffusion models beyond using the additional data of the pre-training process
for augmentation lead to improved downstream performance. We perform a systematic
evaluation of existing methods to generate images from diffusion models and study
new extensions to assess their benefit for data augmentation. While we find that
personalizing diffusion models towards the target data outperforms simpler prompting
strategies, we also show that using the training data of the diffusion model alone,
via a simple nearest neighbor retrieval procedure, leads to even stronger downstream
performance. Overall, our study probes the limitations of diffusion models for
data augmentation but also highlights its potential in generating new training
data to improve performance on simple downstream vision tasks.

text: 'Causal discovery methods are intrinsically constrained by the set of assumptions
needed to ensure structure identifiability. Moreover additional restrictions are
often imposed in order to simplify the inference task: this is the case for the
Gaussian noise assumption on additive non-linear models, which is common to many
causal discovery approaches. In this paper we show the shortcomings of inference
under this hypothesis, analyzing the risk of edge inversion under violation of
Gaussianity of the noise terms. Then, we propose a novel method for inferring
the topological ordering of the variables in the causal graph, from data generated
according to an additive non-linear model with a generic noise distribution. This
leads to NoGAM (Not only Gaussian Additive noise Models), a causal discovery algorithm
with a minimal set of assumptions and state of the art performance, experimentally
benchmarked on synthetic data.'

text: This paper demonstrates how to discover the whole causal graph from the second
derivative of the log-likelihood in observational non-linear additive Gaussian
noise models. Leveraging scalable machine learning approaches to approximate the
score function ∇logp(X), we extend the work of Rolland et al. (2022) that only
recovers the topological order from the score and requires an expensive pruning
step removing spurious edges among those admitted by the ordering. Our analysis
leads to DAS (acronym for Discovery At Scale), a practical algorithm that reduces
the complexity of the pruning by a factor proportional to the graph size. In practice,
DAS achieves competitive accuracy with current state-of-the-art while being over
an order of magnitude faster. Overall, our approach enables principled and scalable
causal discovery, significantly lowering the compute bar.

text: 'Recent years have seen a surge of interest in learning high-level causal
representations from low-level image pairs under interventions. Yet, existing
efforts are largely limited to simple synthetic settings that are far away from
real-world problems. In this paper, we present Causal Triplet, a causal representation
learning benchmark featuring not only visually more complex scenes, but also two
crucial desiderata commonly overlooked in previous works: (i) an actionable counterfactual
setting, where only certain object-level variables allow for counterfactual observations
whereas others do not; (ii) an interventional downstream task with an emphasis
on out-of-distribution robustness from the independent causal mechanisms principle.
Through extensive experiments, we find that models built with the knowledge of
disentangled or object-centric representations significantly outperform their
distributed counterparts. However, recent causal representation learning methods
still struggle to identify such latent structures, indicating substantial challenges
and opportunities for future work.'

text: 'Neural networks embed the geometric structure of a data manifold lying in
a high-dimensional space into latent representations. Ideally, the distribution
of the data points in the latent space should depend only on the task, the data,
the loss, and other architecture-specific constraints. However, factors such as
the random weights initialization, training hyperparameters, or other sources
of randomness in the training phase may induce incoherent latent spaces that hinder
any form of reuse. Nevertheless, we empirically observe that, under the same data
and modeling choices, the angles between the encodings within distinct latent
spaces do not change. In this work, we propose the latent similarity between each
sample and a fixed set of anchors as an alternative data representation, demonstrating
that it can enforce the desired invariances without any additional training. We
show how neural architectures can leverage these relative representations to guarantee,
in practice, invariance to latent isometries and rescalings, effectively enabling
latent space communication: from zero-shot model stitching to latent space comparison
between diverse settings. We extensively validate the generalization capability
of our approach on different datasets, spanning various modalities (images, text,
graphs), tasks (e.g., classification, reconstruction) and architectures (e.g.,
CNNs, GCNs, transformers).'

text: Learning generative object models from unlabelled videos is a long standing
problem and required for causal scene modeling. We decompose this problem into
three easier subtasks, and provide candidate solutions for each of them. Inspired
by the Common Fate Principle of Gestalt Psychology, we first extract (noisy) masks
of moving objects via unsupervised motion segmentation. Second, generative models
are trained on the masks of the background and the moving objects, respectively.
Third, background and foreground models are combined in a conditional "dead leaves"
scene model to sample novel scene configurations where occlusions and depth layering
arise naturally. To evaluate the individual stages, we introduce the Fishbowl
dataset positioned between complex real-world scenes and common object-centric
benchmarks of simplistic objects. We show that our approach allows learning generative
models that generalize beyond the occlusions present in the input videos, and
represent scenes in a modular fashion that allows sampling plausible scenes outside
the training distribution by permitting, for instance, object numbers or densities
not observed in the training set.

text: Humans naturally decompose their environment into entities at the appropriate
level of abstraction to act in the world. Allowing machine learning algorithms
to derive this decomposition in an unsupervised way has become an important line
of research. However, current methods are restricted to simulated data or require
additional information in the form of motion or depth in order to successfully
discover objects. In this work, we overcome this limitation by showing that reconstructing
features from models trained in a self-supervised manner is a sufficient training
signal for object-centric representations to arise in a fully unsupervised way.
Our approach, DINOSAUR, significantly out-performs existing image-based object-centric
learning models on simulated data and is the first unsupervised object-centric
model that scales to real-world datasets such as COCO and PASCAL VOC. DINOSAUR
is conceptually simple and shows competitive performance compared to more involved
pipelines from the computer vision literature.

text: "In this paper, we show that recent advances in self-supervised feature\r\nlearning
enable unsupervised object discovery and semantic segmentation with a\r\nperformance
that matches the state of the field on supervised semantic\r\nsegmentation 10
years ago. We propose a methodology based on unsupervised\r\nsaliency masks and
self-supervised feature clustering to kickstart object\r\ndiscovery followed by
training a semantic segmentation network on pseudo-labels\r\nto bootstrap the
system on images with multiple objects. We present results on\r\nPASCAL VOC that
go far beyond the current state of the art (50.0 mIoU), and we\r\nreport for the
first time results on MS COCO for the whole set of 81 classes:\r\nour method discovers
34 categories with more than $20\\%$ IoU, while obtaining\r\nan average IoU of
19.6 for all 81 categories."

text: "As causal ground truth is incredibly rare, causal discovery algorithms are\r\ncommonly
only evaluated on simulated data. This is concerning, given that\r\nsimulations
reflect common preconceptions about generating processes regarding\r\nnoise distributions,
model classes, and more. In this work, we propose a novel\r\nmethod for falsifying
the output of a causal discovery algorithm in the absence\r\nof ground truth.
Our key insight is that while statistical learning seeks\r\nstability across subsets
of data points, causal learning should seek stability\r\nacross subsets of variables.
Motivated by this insight, our method relies on a\r\nnotion of compatibility between
causal graphs learned on different subsets of\r\nvariables. We prove that detecting
incompatibilities can falsify wrongly\r\ninferred causal relations due to violation
of assumptions or errors from finite\r\nsample effects. Although passing such
compatibility tests is only a necessary\r\ncriterion for good performance, we
argue that it provides strong evidence for\r\nthe causal models whenever compatibility
entails strong implications for the\r\njoint distribution. We also demonstrate
experimentally that detection of\r\nincompatibilities can aid in causal model
selection."

text: Living tissues are characterized by an intrinsically mechanochemical interplay
of active physical forces and complex biochemical signaling pathways. Either feature
alone can give rise to complex emergent phenomena, for example, mechanically driven
glassy dynamics and rigidity transitions, or chemically driven reaction-diffusion
instabilities. An important question is how to quantitatively assess the contribution
of these different cues to the large-scale dynamics of biological materials. We
address this in Madin-Darby canine kidney (MDCK) monolayers, considering both
mechanochemical feedback between extracellular signal-regulated kinase (ERK) signaling
activity and cellular density as well as a mechanically active tissue rheology
via a self-propelled vertex model. We show that the relative strength of active
migration forces to mechanochemical couplings controls a transition from a uniform
active glass to periodic spatiotemporal waves. We parametrize the model from published
experimental data sets on MDCK monolayers and use it to make new predictions on
the correlation functions of cellular dynamics and the dynamics of topological
defects associated with the oscillatory phase of cells. Interestingly, MDCK monolayers
are best described by an intermediary parameter region in which both mechanochemical
couplings and noisy active propulsion have a strong influence on the dynamics.
Finally, we study how tissue rheology and ERK waves produce feedback on one another
and uncover a mechanism via which tissue fluidity can be controlled by mechanochemical
waves at both the local and global levels.

text: The execution of cognitive functions requires coordinated circuit activity
across different brain areas that involves the associated firing of neuronal assemblies.
Here, we tested the circuit mechanism behind assembly interactions between the
hippocampus and the medial prefrontal cortex (mPFC) of adult rats by recording
neuronal populations during a rule-switching task. We identified functionally
coupled CA1-mPFC cells that synchronized their activity beyond that expected from
common spatial coding or oscillatory firing. When such cell pairs fired together,
the mPFC cell strongly phase locked to CA1 theta oscillations and maintained consistent
theta firing phases, independent of the theta timing of their CA1 counterpart.
These functionally connected CA1-mPFC cells formed interconnected assemblies.
While firing together with their CA1 assembly partners, mPFC cells fired along
specific theta sequences. Our results suggest that upregulated theta oscillatory
firing of mPFC cells can signal transient interactions with specific CA1 assemblies,
thus enabling distributed computations.

text: During apoptosis, caspases degrade 8 out of ~30 nucleoporins to irreversibly
demolish the nuclear pore complex. However, for poorly understood reasons, caspases
are also activated during cell differentiation. Here, we show that sublethal activation
of caspases during myogenesis results in the transient proteolysis of four peripheral
Nups and one transmembrane Nup. ‘Trimmed’ NPCs become nuclear export-defective,
and we identified in an unbiased manner several classes of cytoplasmic, plasma
membrane, and mitochondrial proteins that rapidly accumulate in the nucleus. NPC
trimming by non-apoptotic caspases was also observed in neurogenesis and endoplasmic
reticulum stress. Our results suggest that caspases can reversibly modulate nuclear
transport activity, which allows them to function as agents of cell differentiation
and adaptation at sublethal levels.

text: "We study multigraphs whose edge-sets are the union of three perfect matchings,
M1, M2, and M3. Given such a graph G and any a1; a2; a3 2 N with a1 +a2 +a3 6
n - 2, we show there exists a matching M of G with jM \\ Mij = ai for each i 2
f1; 2; 3g. The bound n - 2 in the theorem is best possible in general. We conjecture
however that if G is bipartite, the same result holds with n - 2 replaced by n
- 1. We give a construction that shows such a result would be tight. We\r\nalso
make a conjecture generalising the Ryser-Brualdi-Stein conjecture with colour\r\nmultiplicities."

text: "Probabilistic recurrence relations (PRRs) are a standard formalism for describing
the runtime of a randomized algorithm. Given a PRR and a time limit κ, we consider
the tail probability Pr[T≥κ], i.e., the probability that the randomized runtime
T of the PRR exceeds κ. Our focus is the formal analysis of tail bounds that aims
at finding a tight asymptotic upper bound u≥Pr[T≥κ]. To address this problem,
the classical and most well-known approach is the cookbook method by Karp (JACM
1994), while other approaches are mostly limited to deriving tail bounds of specific
PRRs via involved custom analysis.\r\nIn this work, we propose a novel approach
for deriving the common exponentially-decreasing tail bounds for PRRs whose preprocessing
time and random passed sizes observe discrete or (piecewise) uniform distribution
and whose recursive call is either a single procedure call or a divide-and-conquer.
We first establish a theoretical approach via Markov’s inequality, and then instantiate
the theoretical approach with a template-based algorithmic approach via a refined
treatment of exponentiation. Experimental evaluation shows that our algorithmic
approach is capable of deriving tail bounds that are (i) asymptotically tighter
than Karp’s method, (ii) match the best-known manually-derived asymptotic tail
bound for QuickSelect, and (iii) is only slightly worse (with a loglogn factor)
than the manually-proven optimal asymptotic tail bound for QuickSort. Moreover,
our algorithmic approach handles all examples (including realistic PRRs such as
QuickSort, QuickSelect, DiameterComputation, etc.) in less than 0.1 s, showing
that our approach is efficient in practice."

text: "Markov decision processes can be viewed as transformers of probability distributions.
While this view is useful from a practical standpoint to reason about trajectories
of distributions, basic reachability and safety problems are known to be computationally
intractable (i.e., Skolem-hard) to solve in such models. Further, we show that
even for simple examples of MDPs, strategies for safety objectives over distributions
can require infinite memory and randomization.\r\nIn light of this, we present
a novel overapproximation approach to synthesize strategies in an MDP, such that
a safety objective over the distributions is met. More precisely, we develop a
new framework for template-based synthesis of certificates as affine distributional
and inductive invariants for safety objectives in MDPs. We provide two algorithms
within this framework. One can only synthesize memoryless strategies, but has
relative completeness guarantees, while the other can synthesize general strategies.
The runtime complexity of both algorithms is in PSPACE. We implement these algorithms
and show that they can solve several non-trivial examples."

text: Clathrin-mediated vesicle trafficking plays central roles in post-Golgi transport.
In yeast (Saccharomyces cerevisiae), the AP-1 complex and GGA adaptors are predicted
to generate distinct transport vesicles at the trans-Golgi network (TGN), and
the epsin-related proteins Ent3p and Ent5p (collectively Ent3p/5p) act as accessories
for these adaptors. Recently, we showed that vesicle transport from the TGN is
crucial for yeast Rab5 (Vps21p)-mediated endosome formation, and that Ent3p/5p
are crucial for this process, whereas AP-1 and GGA adaptors are dispensable. However,
these observations were incompatible with previous studies showing that these
adaptors are required for Ent3p/5p recruitment to the TGN, and thus the overall
mechanism responsible for regulation of Vps21p activity remains ambiguous. Here,
we investigated the functional relationships between clathrin adaptors in post-Golgi-mediated
Vps21p activation. We show that AP-1 disruption in the ent3Δ5Δ mutant impaired
transport of the Vps21p guanine nucleotide exchange factor Vps9p transport to
the Vps21p compartment and severely reduced Vps21p activity. Additionally, GGA
adaptors, the phosphatidylinositol-4-kinase Pik1p and Rab11 GTPases Ypt31p and
Ypt32p were found to have partially overlapping functions for recruitment of AP-1
and Ent3p/5p to the TGN. These findings suggest a distinct role of clathrin adaptors
for Vps21p activation in the TGN–endosome trafficking pathway.
