text: Solid-state microwave systems offer strong interactions for fast quantum logic
and sensing but photons at telecom wavelength are the ideal choice for high-density
low-loss quantum interconnects. A general-purpose interface that can make use
of single photon effects requires < 1 input noise quanta, which has remained elusive
due to either low efficiency or pump induced heating. Here we demonstrate coherent
electro-optic modulation on nanosecond-timescales with only 0.16+0.02−0.01 microwave
input noise photons with a total bidirectional transduction efficiency of 8.7%
(or up to 15% with 0.41+0.02−0.02), as required for near-term heralded quantum
network protocols. The use of short and high-power optical pump pulses also enables
near-unity cooperativity of the electro-optic interaction leading to an internal
pure conversion efficiency of up to 99.5%. Together with the low mode occupancy
this provides evidence for electro-optic laser cooling and vacuum amplification
as predicted a decade ago.

text: Eurasian brine shrimp (genus Artemia) have closely related sexual and asexual
lineages of parthenogenetic females, which produce rare males at low frequencies.
Although they are known to have ZW chromosomes, these are not well characterized,
and it is unclear whether they are shared across the clade. Furthermore, the underlying
genetic architecture of the transmission of asexuality, which can occur when rare
males mate with closely related sexual females, is not well understood. We produced
a chromosome-level assembly for the sexual Eurasian species Artemia sinica and
characterized in detail the pair of sex chromosomes of this species. We combined
this new assembly with short-read genomic data for the sexual species Artemia
sp. Kazakhstan and several asexual lineages of Artemia parthenogenetica, allowing
us to perform an in-depth characterization of sex-chromosome evolution across
the genus. We identified a small differentiated region of the ZW pair that is
shared by all sexual and asexual lineages, supporting the shared ancestry of the
sex chromosomes. We also inferred that recombination suppression has spread to
larger sections of the chromosome independently in the American and Eurasian lineages.
Finally, we took advantage of a rare male, which we backcrossed to sexual females,
to explore the genetic basis of asexuality. Our results suggest that parthenogenesis
is likely partly controlled by a locus on the Z chromosome, highlighting the interplay
between sex determination and asexuality.

text: The t-haplotype of mice is a classical model for autosomal transmission distortion.
A largely non-recombining variant of the proximal region of chromosome 17, it
is transmitted to more than 90% of the progeny of heterozygous males through the
disabling of sperm carrying a standard chromosome. While extensive genetic and
functional work has shed light on individual genes involved in drive, much less
is known about the evolution and function of the rest of its hundreds of genes.
Here, we characterize the sequence and expression of dozens of t-specific transcripts
and of their chromosome 17 homologues. Many genes showed reduced expression of
the t-allele, but an equal number of genes showed increased expression of their
t-copy, consistent with increased activity or a newly evolved function. Genes
on the t-haplotype had a significantly higher non-synonymous substitution rate
than their homologues on the standard chromosome, with several genes harbouring
dN/dS ratios above 1. Finally, the t-haplotype has acquired at least two genes
from other chromosomes, which show high and tissue-specific expression. These
results provide a first overview of the gene content of this selfish element,
and support a more dynamic evolutionary scenario than expected of a large genomic
region with almost no recombination.

text: It is practical to collect a huge amount of movement data and environmental
context information along with the health signals of individuals because there
is the emergence of new generations of positioning and tracking technologies and
rapid advancements of health sensors. The study of the relations between these
datasets and their sequence similarity analysis is of interest to many applications
such as health monitoring and recommender systems. However, entering all movement
parameters and health signals can lead to the complexity of the problem and an
increase in its computational load. In this situation, dimension reduction techniques
can be used to avoid consideration of simultaneous dependent parameters in the
process of similarity measurement of the trajectories. The present study provides
a framework, named CaDRAW, to use spatial–temporal data and movement parameters
along with independent context information in the process of measuring the similarity
of trajectories. In this regard, the omission of dependent movement characteristic
signals is conducted by using an unsupervised feature selection dimension reduction
technique. To evaluate the effectiveness of the proposed framework, it was applied
to a real contextualized movement and related health signal datasets of individuals.
The results indicated the capability of the proposed framework in measuring the
similarity and in decreasing the characteristic signals in such a way that the
similarity results -before and after reduction of dependent characteristic signals-
have small differences. The mean differences between the obtained results before
and after reducing the dimension were 0.029 and 0.023 for the round path, respectively.

text: "Social insects are a common model to study disease dynamics in social animals.
Even though pathogens should thrive in social insect colonies as the hosts engage
in frequent social interactions, are closely related and live in a pathogen-rich
environment, disease outbreaks are rare. This is because social insects have evolved
mechanisms to keep pathogens at bay – and fight disease as a collective. Social
insect colonies are often viewed as “superorganisms” with division of labor between
reproductive “germ-like” queens and males and “somatic” workers, which together
form an interdependent reproductive unit that parallels a multicellular body.
Superorganisms possess a “social immune system” that comprises of collective disease
defenses performed by the workers - summarized as “social immunity”. In social
groups immunization (reduced susceptibility to a parasite upon secondary exposure
to the same parasite) can e.g. be triggered by social interactions (“social immunization”).
Social immunization can be caused by (i) asymptomatic low-level infections that
are acquired during caregiving to a contagious individual that can give an immune
boost, which can induce protection upon later encounter with the same pathogen
(active immunization) or (ii) by transfer of immune effectors between individuals
(passive immunization).\r\nIn the second chapter, I built up on a study that I
co-authored that found that low-level infections can not only be protective, but
also be costly and make the host more susceptible to detrimental superinfections
after contact to a very dissimilar pathogen. I here now tested different degrees
of phylogenetically-distant fungal strains of M. brunneum and M. robertsii in
L. neglectus and can describe the occurrence of cross-protection of social immunization
if the first and second pathogen are from the same level. Interestingly, low-level
infections only provided protection when the first strain was less virulent than
the second strain and elicited higher immune gene expression.\r\nIn the third
and fourth chapters, I expanded on the role of social immunity in sexual selection,
a so far unstudied field. I used the fungus Metarhizium robertsii and the ant
Cardiocondyla obscurior as a model, as in this species mating occurs in the presence
of workers and can be studied under laboratory conditions. Before males mate with
virgin queens in the nest they engage in fierce combat over the access to their
mating partners.\r\nFirst, I focused on male-male competition in the third chapter
and found that fighting with a contagious male is costly as it can lead to contamination
of the rival, but that workers can decrease the risk of disease contraction by
performing sanitary care.\r\nIn the fourth chapter, I studied the effect of fungal
infection on survival and mating success of sexuals (freshly emerged queens and
males) and found that worker-performed sanitary care can buffer the negative effect
that a pathogenic contagion would have on sexuals by spore removal from the exposed
individuals. When social immunity was prevented and queens could contract spores
from their mating partner, very low dosages led to negative consequences: their
lifespan was reduced and they produced fewer offspring with poor immunocompetence
compared to healthy queens. Interestingly, cohabitation with a late-stage infected
male where no spore transfer was possible had a positive effect on offspring immunity
– male offspring of mothers that apparently perceived an infected partner in their
vicinity reacted more sensitively to fungal challenge than male offspring without
paternal pathogen history."

text: 'Understanding the properties of neural networks trained via stochastic gradient
descent (SGD) is at the heart of the theory of deep learning. In this work, we
take a mean-field view, and consider a two-layer ReLU network trained via noisy-SGD
for a univariate regularized regression problem. Our main result is that SGD with
vanishingly small noise injected in the gradients is biased towards a simple solution:
at convergence, the ReLU network implements a piecewise linear map of the inputs,
and the number of “knot” points -- i.e., points where the tangent of the ReLU
network estimator changes -- between two consecutive training inputs is at most
three. In particular, as the number of neurons of the network grows, the SGD dynamics
is captured by the solution of a gradient flow and, at convergence, the distribution
of the weights approaches the unique minimizer of a related free energy, which
has a Gibbs form. Our key technical contribution consists in the analysis of the
estimator resulting from this minimizer: we show that its second derivative vanishes
everywhere, except at some specific locations which represent the “knot” points.
We also provide empirical evidence that knots at locations distinct from the data
points might occur, as predicted by our theory.'

text: Weak convergence of inertial iterative method for solving variational inequalities
is the focus of this paper. The cost function is assumed to be non-Lipschitz and
monotone. We propose a projection-type method with inertial terms and give weak
convergence analysis under appropriate conditions. Some test results are performed
and compared with relevant methods in the literature to show the efficiency and
advantages given by our proposed methods.

text: Hematopoietic-specific protein 1 (Hem1) is an essential subunit of the WAVE
regulatory complex (WRC) in immune cells. WRC is crucial for Arp2/3 complex activation
and the protrusion of branched actin filament networks. Moreover, Hem1 loss of
function in immune cells causes autoimmune diseases in humans. Here, we show that
genetic removal of Hem1 in macrophages diminishes frequency and efficacy of phagocytosis
as well as phagocytic cup formation in addition to defects in lamellipodial protrusion
and migration. Moreover, Hem1-null macrophages displayed strong defects in cell
adhesion despite unaltered podosome formation and concomitant extracellular matrix
degradation. Specifically, dynamics of both adhesion and de-adhesion as well as
concomitant phosphorylation of paxillin and focal adhesion kinase (FAK) were significantly
compromised. Accordingly, disruption of WRC function in non-hematopoietic cells
coincided with both defects in adhesion turnover and altered FAK and paxillin
phosphorylation. Consistently, platelets exhibited reduced adhesion and diminished
integrin αIIbβ3 activation upon WRC removal. Interestingly, adhesion phenotypes,
but not lamellipodia formation, were partially rescued by small molecule activation
of FAK. A full rescue of the phenotype, including lamellipodia formation, required
not only the presence of WRCs but also their binding to and activation by Rac.
Collectively, our results uncover that WRC impacts on integrin-dependent processes
in a FAK-dependent manner, controlling formation and dismantling of adhesions,
relevant for properly grabbing onto extracellular surfaces and particles during
cell edge expansion, like in migration or phagocytosis.

text: Combining hybrid zone analysis with genomic data is a promising approach to
understanding the genomic basis of adaptive divergence. It allows for the identification
of genomic regions underlying barriers to gene flow. It also provides insights
into spatial patterns of allele frequency change, informing about the interplay
between environmental factors, dispersal and selection. However, when only a single
hybrid zone is analysed, it is difficult to separate patterns generated by selection
from those resulting from chance. Therefore, it is beneficial to look for repeatable
patterns across replicate hybrid zones in the same system. We applied this approach
to the marine snail Littorina saxatilis, which contains two ecotypes, adapted
to wave-exposed rocks vs. high-predation boulder fields. The existence of numerous
hybrid zones between ecotypes offered the opportunity to test for the repeatability
of genomic architectures and spatial patterns of divergence. We sampled and phenotyped
snails from seven replicate hybrid zones on the Swedish west coast and genotyped
them for thousands of single nucleotide polymorphisms. Shell shape and size showed
parallel clines across all zones. Many genomic regions showing steep clines and/or
high differentiation were shared among hybrid zones, consistent with a common
evolutionary history and extensive gene flow between zones, and supporting the
importance of these regions for divergence. In particular, we found that several
large putative inversions contribute to divergence in all locations. Additionally,
we found evidence for consistent displacement of clines from the boulder–rock
transition. Our results demonstrate patterns of spatial variation that would not
be accessible without continuous spatial sampling, a large genomic data set and
replicate hybrid zones.

text: 'We study the two-player zero-sum extension of the partially observable stochastic
shortest-path problem where one agent has only partial information about the environment.
We formulate this problem as a partially observable stochastic game (POSG): given
a set of target states and negative rewards for each transition, the player with
imperfect information maximizes the expected undiscounted total reward until a
target state is reached. The second player with the perfect information aims for
the opposite. We base our formalism on POSGs with one-sided observability (OS-POSGs)
and give the following contributions: (1) we introduce a novel heuristic search
value iteration algorithm that iteratively solves depth-limited variants of the
game, (2) we derive the bound on the depth guaranteeing an arbitrary precision,
(3) we propose a novel upper-bound estimation that allows early terminations,
and (4) we experimentally evaluate the algorithm on a pursuit-evasion game.'

text: Dynamic Connectivity is a fundamental algorithmic graph problem, motivated
by a wide range of applications to social and communication networks and used
as a building block in various other algorithms, such as the bi-connectivity and
the dynamic minimal spanning tree problems. In brief, we wish to maintain the
connected components of the graph under dynamic edge insertions and deletions.
In the sequential case, the problem has been well-studied from both theoretical
and practical perspectives. However, much less is known about efficient concurrent
solutions to this problem. This is the gap we address in this paper. We start
from one of the classic data structures used to solve this problem, the Euler
Tour Tree. Our first contribution is a non-blocking single-writer implementation
of it. We leverage this data structure to obtain the first truly concurrent generalization
of dynamic connectivity, which preserves the time complexity of its sequential
counterpart, but is also scalable in practice. To achieve this, we rely on three
main techniques. The first is to ensure that connectivity queries, which usually
dominate real-world workloads, are non-blocking. The second non-trivial technique
expands the above idea by making all queries that do not change the connectivity
structure non-blocking. The third ingredient is applying fine-grained locking
for updating the connected components, which allows operations on disjoint components
to occur in parallel. We evaluate the resulting algorithm on various workloads,
executing on both real and synthetic graphs. The results show the efficiency of
each of the proposed optimizations; the most efficient variant improves the performance
of a coarse-grained based implementation on realistic scenarios up to 6x on average
and up to 30x when connectivity queries dominate.

text: "Consider a distributed task where the communication network is fixed but
the local inputs given to the nodes of the distributed system may change over
time. In this work, we explore the following question: if some of the local inputs
change, can an existing solution be updated efficiently, in a dynamic and distributed
manner?\r\nTo address this question, we define the batch dynamic CONGEST model
in which we are given a bandwidth-limited communication network and a dynamic
edge labelling defines the problem input. The task is to maintain a solution to
a graph problem on the labelled graph under batch changes. We investigate, when
a batch of alpha edge label changes arrive, - how much time as a function of alpha
we need to update an existing solution, and - how much information the nodes have
to keep in local memory between batches in order to update the solution quickly.\r\nOur
work lays the foundations for the theory of input-dynamic distributed network
algorithms. We give a general picture of the complexity landscape in this model,
design both universal algorithms and algorithms for concrete problems, and present
a general framework for lower bounds. The diverse time complexity of our model
spans from constant time, through time polynomial in alpha, and to alpha time,
which we show to be enough for any task."

which we formulate in a geometric way. We estimate the length of the projection

text: The cost-effective conversion of low-grade heat into electricity using thermoelectric
devices requires developing alternative materials and material processing technologies
able to reduce the currently high device manufacturing costs. In this direction,
thermoelectric materials that do not rely on rare or toxic elements such as tellurium
or lead need to be produced using high-throughput technologies not involving high
temperatures and long processes. Bi2Se3 is an obvious possible Te-free alternative
to Bi2Te3 for ambient temperature thermoelectric applications, but its performance
is still low for practical applications, and additional efforts toward finding
proper dopants are required. Here, we report a scalable method to produce Bi2Se3
nanosheets at low synthesis temperatures. We studied the influence of different
dopants on the thermoelectric properties of this material. Among the elements
tested, we demonstrated that Sn doping resulted in the best performance. Sn incorporation
resulted in a significant improvement to the Bi2Se3 Seebeck coefficient and a
reduction in the thermal conductivity in the direction of the hot-press axis,
resulting in an overall 60% improvement in the thermoelectric figure of merit
of Bi2Se3.

text: A tight frame is the orthogonal projection of some orthonormal basis of Rn
onto Rk. We show that a set of vectors is a tight frame if and only if the set
of all cross products of these vectors is a tight frame. We reformulate a range
of problems on the volume of projections (or sections) of regular polytopes in
terms of tight frames and write a first-order necessary condition for local extrema
of these problems. As applications, we prove new results for the problem of maximization
of the volume of zonotopes.

text: Brain dynamics display collective phenomena as diverse as neuronal oscillations
and avalanches. Oscillations are rhythmic, with fluctuations occurring at a characteristic
scale, whereas avalanches are scale-free cascades of neural activity. Here we
show that such antithetic features can coexist in a very generic class of adaptive
neural networks. In the most simple yet fully microscopic model from this class
we 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 fluctuations, collective behaviors of nearly-synchronous extreme events
on multiple sensors, to neuronal avalanches unfolding over multiple sensors across
multiple time-bins. Importantly, the inferred parameters correlate with model-independent
signatures of "closeness to criticality", suggesting that the coexistence of scale-specific
(neural oscillations) and scale-free (neuronal avalanches) dynamics in brain activity
occurs close to a non-equilibrium critical point at the onset of self-sustained
oscillations.

text: In order to combat molecular damage, most cellular proteins undergo rapid
turnover. We have previously identified large nuclear protein assemblies that
can persist for years in post-mitotic tissues and are subject to age-related decline.
Here, we report that mitochondria can be long lived in the mouse brain and reveal
that specific mitochondrial proteins have half-lives longer than the average proteome.
These mitochondrial long-lived proteins (mitoLLPs) are core components of the
electron transport chain (ETC) and display increased longevity in respiratory
supercomplexes. We find that COX7C, a mitoLLP that forms a stable contact site
between complexes I and IV, is required for complex IV and supercomplex assembly.
Remarkably, even upon depletion of COX7C transcripts, ETC function is maintained
for days, effectively uncoupling mitochondrial function from ongoing transcription
of its mitoLLPs. Our results suggest that modulating protein longevity within
the ETC is critical for mitochondrial proteome maintenance and the robustness
of mitochondrial function.
