text: Photorealistic editing of head portraits is a challenging task as humans are
very sensitive to inconsistencies in faces. We present an approach for high-quality
intuitive editing of the camera viewpoint and scene illumination (parameterised
with an environment map) in a portrait image. This requires our method to capture
and control the full reflectance field of the person in the image. Most editing
approaches rely on supervised learning using training data captured with setups
such as light and camera stages. Such datasets are expensive to acquire, not readily
available and do not capture all the rich variations of in-the-wild portrait images.
In addition, most supervised approaches only focus on relighting, and do not allow
camera viewpoint editing. Thus, they only capture and control a subset of the
reflectance field. Recently, portrait editing has been demonstrated by operating
in the generative model space of StyleGAN. While such approaches do not require
direct supervision, there is a significant loss of quality when compared to the
supervised approaches. In this paper, we present a method which learns from limited
supervised training data. The training images only include people in a fixed neutral
expression with eyes closed, without much hair or background variations. Each
person is captured under 150 one-light-at-a-time conditions and under 8 camera
poses. Instead of training directly in the image space, we design a supervised
problem which learns transformations in the latent space of StyleGAN. This combines
the best of supervised learning and generative adversarial modeling. We show that
the StyleGAN prior allows for generalisation to different expressions, hairstyles
and backgrounds. This produces high-quality photorealistic results for in-the-wild
images and significantly outperforms existing methods. Our approach can edit the
illumination and pose simultaneously, and runs at interactive rates.

text: Material appearance hinges on material reflectance properties but also surface
geometry and illumination. The unlimited number of potential combinations between
these factors makes understanding and predicting material appearance a very challenging
task. In this work, we collect a large-scale dataset of perceptual ratings of
appearance attributes with more than 215,680 responses for 42,120 distinct combinations
of material, shape, and illumination. The goal of this dataset is twofold. First,
we analyze for the first time the effects of illumination and geometry in material
perception across such a large collection of varied appearances. We connect our
findings to those of the literature, discussing how previous knowledge generalizes
across very diverse materials, shapes, and illuminations. Second, we use the collected
dataset to train a deep learning architecture for predicting perceptual attributes
that correlate with human judgments. We demonstrate the consistent and robust
behavior of our predictor in various challenging scenarios, which, for the first
time, enables estimating perceived material attributes from general 2D images.
Since our predictor relies on the final appearance in an image, it can compare
appearance properties across different geometries and illumination conditions.
Finally, we demonstrate several applications that use our predictor, including
appearance reproduction using 3D printing, BRDF editing by integrating our predictor
in a differentiable renderer, illumination design, or material recommendations
for scene design.

text: Heart rate variability (hrv) is a physiological phenomenon of the variation
in the length of the time interval between consecutive heartbeats. In many cases
it could be an indicator of the development of pathological states. The classical
approach to the analysis of hrv includes time domain methods and frequency domain
methods. However, attempts are still being made to define new and more effective
hrv assessment tools. Persistent homology is a novel data analysis tool developed
in the recent decades that is rooted at algebraic topology. The Topological Data
Analysis (TDA) approach focuses on examining the shape of the data in terms of
connectedness and holes, and has recently proved to be very effective in various
fields of research. In this paper we propose the use of persistent homology to
the hrv analysis. We recall selected topological descriptors used in the literature
and we introduce some new topological descriptors that reflect the specificity
of hrv, and we discuss their relation to the standard hrv measures. In particular,
we show that this novel approach provides a collection of indices that might be
at least as useful as the classical parameters in differentiating between series
of beat-to-beat intervals (RR-intervals) in healthy subjects and patients suffering
from a stroke episode.

text: Attachment of adhesive molecules on cell culture surfaces to restrict cell
adhesion to defined areas and shapes has been vital for the progress of in vitro
research. In currently existing patterning methods, a combination of pattern properties
such as stability, precision, specificity, high-throughput outcome, and spatiotemporal
control is highly desirable but challenging to achieve. Here, we introduce a versatile
and high-throughput covalent photoimmobilization technique, comprising a light-dose-dependent
patterning step and a subsequent functionalization of the pattern via click chemistry.
This two-step process is feasible on arbitrary surfaces and allows for generation
of sustainable patterns and gradients. The method is validated in different biological
systems by patterning adhesive ligands on cell-repellent surfaces, thereby constraining
the growth and migration of cells to the designated areas. We then implement a
sequential photopatterning approach by adding a second switchable patterning step,
allowing for spatiotemporal control over two distinct surface patterns. As a proof
of concept, we reconstruct the dynamics of the tip/stalk cell switch during angiogenesis.
Our results show that the spatiotemporal control provided by our “sequential photopatterning”
system is essential for mimicking dynamic biological processes and that our innovative
approach has great potential for further applications in cell science.

text: "Approximate agreement is one of the few variants of consensus that can be
solved in a wait-free manner in asynchronous systems where processes communicate
by reading and writing to shared memory. In this work, we consider a natural generalisation
of approximate agreement on arbitrary undirected connected graphs. Each process
is given a vertex of the graph as input and, if non-faulty, must output a vertex
such that\r\nall the outputs are within distance 1 of one another, and\r\n\r\neach
output value lies on a shortest path between two input values.\r\n\r\nFrom prior
work, it is known that there is no wait-free algorithm among \U0001D45B≥3 processes
for this problem on any cycle of length \U0001D450≥4 , by reduction from 2-set
agreement (Castañeda et al. 2018).\r\n\r\nIn this work, we investigate the solvability
and complexity of this task on general graphs. We give a new, direct proof of
the impossibility of approximate agreement on cycles of length \U0001D450≥4
, via a generalisation of Sperner’s Lemma to convex polygons. We also extend the
reduction from 2-set agreement to a larger class of graphs, showing that approximate
agreement on these graphs is unsolvable. On the positive side, we present a wait-free
algorithm for a class of graphs that properly contains the class of chordal graphs."

text: We define a new compact coordinate system in which each integer triplet addresses
a voxel in the BCC grid, and we investigate some of its properties. We propose
a characterization of 3D discrete analytical planes with their topological features
(in the Cartesian and in the new coordinate system) such as the interrelation
between the thickness of the plane and the separability constraint we aim to obtain.

text: "The dual attack has long been considered a relevant attack on lattice-based
cryptographic schemes relying on the hardness of learning with errors (LWE) and
its structured variants. As solving LWE corresponds to finding a nearest point
on a lattice, one may naturally wonder how efficient this dual approach is for
solving more general closest vector problems, such as the classical closest vector
problem (CVP), the variants bounded distance decoding (BDD) and approximate CVP,
and preprocessing versions of these problems. While primal, sieving-based solutions
to these problems (with preprocessing) were recently studied in a series of works
on approximate Voronoi cells [Laa16b, DLdW19, Laa20, DLvW20], for the dual attack
no such overview exists, especially for problems with preprocessing. With one
of the take-away messages of the approximate Voronoi cell line of work being that
primal attacks work well for approximate CVP(P) but scale poorly for BDD(P), one
may further wonder if the dual attack suffers the same drawbacks, or if it is
perhaps a better solution when trying to solve BDD(P).\r\n\r\nIn this work we
provide an overview of cost estimates for dual algorithms for solving these “classical”
closest lattice vector problems. Heuristically we expect to solve the search version
of average-case CVPP in time and space 20.293\U0001D451+\U0001D45C(\U0001D451)
\ in the single-target model. The distinguishing version of average-case CVPP,
where we wish to distinguish between random targets and targets planted at distance
(say) 0.99⋅\U0001D454\U0001D451 from the lattice, has the same complexity in
the single-target model, but can be solved in time and space 20.195\U0001D451+\U0001D45C(\U0001D451)
\ in the multi-target setting, when given a large number of targets from either
target distribution. This suggests an inequivalence between distinguishing and
searching, as we do not expect a similar improvement in the multi-target setting
to hold for search-CVPP. We analyze three slightly different decoders, both for
distinguishing and searching, and experimentally obtain concrete cost estimates
for the dual attack in dimensions 50 to 80, which confirm our heuristic assumptions,
and show that the hidden order terms in the asymptotic estimates are quite small.\r\n\r\nOur
main take-away message is that the dual attack appears to mirror the approximate
Voronoi cell line of work – whereas using approximate Voronoi cells works well
for approximate CVP(P) but scales poorly for BDD(P), the dual approach scales
well for BDD(P) instances but performs poorly on approximate CVP(P)."

text: "Automated contract tracing aims at supporting manual contact tracing during
pandemics by alerting users of encounters with infected people. There are currently
many proposals for protocols (like the “decentralized” DP-3T and PACT or the “centralized”
ROBERT and DESIRE) to be run on mobile phones, where the basic idea is to regularly
broadcast (using low energy Bluetooth) some values, and at the same time store
(a function of) incoming messages broadcasted by users in their proximity. In
the existing proposals one can trigger false positives on a massive scale by an
“inverse-Sybil” attack, where a large number of devices (malicious users or hacked
phones) pretend to be the same user, such that later, just a single person needs
to be diagnosed (and allowed to upload) to trigger an alert for all users who
were in proximity to any of this large group of devices.\r\n\r\nWe propose the
first protocols that do not succumb to such attacks assuming the devices involved
in the attack do not constantly communicate, which we observe is a necessary assumption.
The high level idea of the protocols is to derive the values to be broadcasted
by a hash chain, so that two (or more) devices who want to launch an inverse-Sybil
attack will not be able to connect their respective chains and thus only one of
them will be able to upload. Our protocols also achieve security against replay,
belated replay, and one of them even against relay attacks."

text: 'The Nearest neighbour search (NNS) is a fundamental problem in many application
domains dealing with multidimensional data. In a concurrent setting, where dynamic
modifications are allowed, a linearizable implementation of the NNS is highly
desirable.This paper introduces the LockFree-kD-tree (LFkD-tree ): a lock-free
concurrent kD-tree, which implements an abstract data type (ADT) that provides
the operations Add, Remove, Contains, and NNS. Our implementation is linearizable.
The operations in the LFkD-tree use single-word read and compare-and-swap (Image
1 ) atomic primitives, which are readily supported on available multi-core processors.
We experimentally evaluate the LFkD-tree using several benchmarks comprising real-world
and synthetic datasets. The experiments show that the presented design is scalable
and achieves significant speed-up compared to the implementations of an existing
sequential kD-tree and a recently proposed multidimensional indexing structure,
PH-tree.'

text: Amplitude demodulation is a classical operation used in signal processing.
For a long time, its effective applications in practice have been limited to narrowband
signals. In this work, we generalize amplitude demodulation to wideband signals.
We pose demodulation as a recovery problem of an oversampled corrupted signal
and introduce special iterative schemes belonging to the family of alternating
projection algorithms to solve it. Sensibly chosen structural assumptions on the
demodulation outputs allow us to reveal the high inferential accuracy of the method
over a rich set of relevant signals. This new approach surpasses current state-of-the-art
demodulation techniques apt to wideband signals in computational efficiency by
up to many orders of magnitude with no sacrifice in quality. Such performance
opens the door for applications of the amplitude demodulation procedure in new
contexts. In particular, the new method makes online and large-scale offline data
processing feasible, including the calculation of modulator-carrier pairs in higher
dimensions and poor sampling conditions, independent of the signal bandwidth.
We illustrate the utility and specifics of applications of the new method in practice
by using natural speech and synthetic signals.

text: In 2020, many in-person scientific events were canceled due to the COVID-19
pandemic, creating a vacuum in networking and knowledge exchange between scientists.
To fill this void in scientific communication, a group of early career nanocrystal
enthusiasts launched the virtual seminar series, News in Nanocrystals, in the
summer of 2020. By the end of the year, the series had attracted over 850 participants
from 46 countries. In this Nano Focus, we describe the process of organizing the
News in Nanocrystals seminar series; discuss its growth, emphasizing what the
organizers have learned in terms of diversity and accessibility; and provide an
outlook for the next steps and future opportunities. This summary and analysis
of experiences and learned lessons are intended to inform the broader scientific
community, especially those who are looking for avenues to continue fostering
discussion and scientific engagement virtually, both during the pandemic and after.

text: Myocardial regeneration is restricted to early postnatal life, when mammalian
cardiomyocytes still retain the ability to proliferate. The molecular cues that
induce cell cycle arrest of neonatal cardiomyocytes towards terminally differentiated
adult heart muscle cells remain obscure. Here we report that the miR-106b~25 cluster
is higher expressed in the early postnatal myocardium and decreases in expression
towards adulthood, especially under conditions of overload, and orchestrates the
transition of cardiomyocyte hyperplasia towards cell cycle arrest and hypertrophy
by virtue of its targetome. In line, gene delivery of miR-106b~25 to the mouse
heart provokes cardiomyocyte proliferation by targeting a network of negative
cell cycle regulators including E2f5, Cdkn1c, Ccne1 and Wee1. Conversely, gene-targeted
miR-106b~25 null mice display spontaneous hypertrophic remodeling and exaggerated
remodeling to overload by derepression of the prohypertrophic transcription factors
Hand2 and Mef2d. Taking advantage of the regulatory function of miR-106b~25 on
cardiomyocyte hyperplasia and hypertrophy, viral gene delivery of miR-106b~25
provokes nearly complete regeneration of the adult myocardium after ischemic injury.
Our data demonstrate that exploitation of conserved molecular programs can enhance
the regenerative capacity of the injured heart.

text: 'Parent-of-origin–dependent gene expression in mammals and flowering plants
results from differing chromatin imprints (genomic imprinting) between maternally
and paternally inherited alleles. Imprinted gene expression in the endosperm of
seeds is associated with localized hypomethylation of maternally but not paternally
inherited DNA, with certain small RNAs also displaying parent-of-origin–specific
expression. To understand the evolution of imprinting mechanisms in Oryza sativa
(rice), we analyzed imprinting divergence among four cultivars that span both
japonica and indica subspecies: Nipponbare, Kitaake, 93-11, and IR64. Most imprinted
genes are imprinted across cultivars and enriched for functions in chromatin and
transcriptional regulation, development, and signaling. However, 4 to 11% of imprinted
genes display divergent imprinting. Analyses of DNA methylation and small RNAs
revealed that endosperm-specific 24-nt small RNA–producing loci show weak RNA-directed
DNA methylation, frequently overlap genes, and are imprinted four times more often
than genes. However, imprinting divergence most often correlated with local DNA
methylation epimutations (9 of 17 assessable loci), which were largely stable
within subspecies. Small insertion/deletion events and transposable element insertions
accompanied 4 of the 9 locally epimutated loci and associated with imprinting
divergence at another 4 of the remaining 8 loci. Correlating epigenetic and genetic
variation occurred at key regulatory regions—the promoter and transcription start
site of maternally biased genes, and the promoter and gene body of paternally
biased genes. Our results reinforce models for the role of maternal-specific DNA
hypomethylation in imprinting of both maternally and paternally biased genes,
and highlight the role of transposition and epimutation in rice imprinting evolution.'

text: Clathrin-mediated endocytosis is the major route of entry of cargos into cells
and thus underpins many physiological processes. During endocytosis, an area of
flat membrane is remodeled by proteins to create a spherical vesicle against intracellular
forces. The protein machinery which mediates this membrane bending in plants is
unknown. However, it is known that plant endocytosis is actin independent, thus
indicating that plants utilize a unique mechanism to mediate membrane bending
against high-turgor pressure compared to other model systems. Here, we investigate
the TPLATE complex, a plant-specific endocytosis protein complex. It has been
thought to function as a classical adaptor functioning underneath the clathrin
coat. However, by using biochemical and advanced live microscopy approaches, we
found that TPLATE is peripherally associated with clathrin-coated vesicles and
localizes at the rim of endocytosis events. As this localization is more fitting
to the protein machinery involved in membrane bending during endocytosis, we examined
cells in which the TPLATE complex was disrupted and found that the clathrin structures
present as flat patches. This suggests a requirement of the TPLATE complex for
membrane bending during plant clathrin–mediated endocytosis. Next, we used in
vitro biophysical assays to confirm that the TPLATE complex possesses protein
domains with intrinsic membrane remodeling activity. These results redefine the
role of the TPLATE complex and implicate it as a key component of the evolutionarily
distinct plant endocytosis mechanism, which mediates endocytic membrane bending
against the high-turgor pressure in plant cells.

text: 'Extending on ideas of Lewin, Lieb, and Seiringer [Phys. Rev. B 100, 035127
(2019)], we present a modified “floating crystal” trial state for jellium (also
known as the classical homogeneous electron gas) with density equal to a characteristic
function. This allows us to show that three definitions of the jellium energy
coincide in dimensions d ≥ 2, thus extending the result of Cotar and Petrache
[“Equality of the Jellium and uniform electron gas next-order asymptotic terms
for Coulomb and Riesz potentials,” arXiv: 1707.07664 (2019)] and Lewin, Lieb,
and Seiringer [Phys. Rev. B 100, 035127 (2019)] that the three definitions coincide
in dimension d ≥ 3. We show that the jellium energy is also equivalent to a “renormalized
energy” studied in a series of papers by Serfaty and others, and thus, by the
work of Bétermin and Sandier [Constr. Approximation 47, 39–74 (2018)], we relate
the jellium energy to the order n term in the logarithmic energy of n points on
the unit 2-sphere. We improve upon known lower bounds for this renormalized energy.
Additionally, we derive formulas for the jellium energy of periodic configurations.'

text: Eigenstate thermalization in quantum many-body systems implies that eigenstates
at high energy are similar to random vectors. Identifying systems where at least
some eigenstates are nonthermal is an outstanding question. In this Letter we
show that interacting quantum models that have a nullspace—a degenerate subspace
of eigenstates at zero energy (zero modes), which corresponds to infinite temperature,
provide a route to nonthermal eigenstates. We analytically show the existence
of a zero mode which can be represented as a matrix product state for a certain
class of local Hamiltonians. In the more general case we use a subspace disentangling
algorithm to generate an orthogonal basis of zero modes characterized by increasing
entanglement entropy. We show evidence for an area-law entanglement scaling of
the least-entangled zero mode in the broad parameter regime, leading to a conjecture
that all local Hamiltonians with the nullspace feature zero modes with area-law
entanglement scaling and, as such, break the strong thermalization hypothesis.
Finally, we find zero modes in constrained models and propose a setup for observing
their experimental signatures.

text: Vaccines are thought to be the best available solution for controlling the
ongoing SARS-CoV-2 pandemic. However, the emergence of vaccine-resistant strains
may come too rapidly for current vaccine developments to alleviate the health,
economic and social consequences of the pandemic. To quantify and characterize
the risk of such a scenario, we created a SIR-derived model with initial stochastic
dynamics of the vaccine-resistant strain to study the probability of its emergence
and establishment. Using parameters realistically resembling SARS-CoV-2 transmission,
we model a wave-like pattern of the pandemic and consider the impact of the rate
of vaccination and the strength of non-pharmaceutical intervention measures on
the probability of emergence of a resistant strain. As expected, we found that
a fast rate of vaccination decreases the probability of emergence of a resistant
strain. Counterintuitively, when a relaxation of non-pharmaceutical interventions
happened at a time when most individuals of the population have already been vaccinated
the probability of emergence of a resistant strain was greatly increased. Consequently,
we show that a period of transmission reduction close to the end of the vaccination
campaign can substantially reduce the probability of resistant strain establishment.
Our results suggest that policymakers and individuals should consider maintaining
non-pharmaceutical interventions and transmission-reducing behaviours throughout
the entire vaccination period.

text: Endometriosis is a common gynecological disorder characterized by ectopic
growth of endometrium outside the uterus and is associated with chronic pain and
infertility. We investigated the role of the long intergenic noncoding RNA 01133
(LINC01133) in endometriosis, an lncRNA that has been implicated in several types
of cancer. We found that LINC01133 is upregulated in ectopic endometriotic lesions.
As expression appeared higher in the epithelial endometrial layer, we performed
a siRNA knockdown of LINC01133 in an endometriosis epithelial cell line. Phenotypic
assays indicated that LINC01133 may promote proliferation and suppress cellular
migration, and affect the cytoskeleton and morphology of the cells. Gene ontology
analysis of differentially expressed genes indicated that cell proliferation and
migration pathways were affected in line with the observed phenotype. We validated
upregulation of p21 and downregulation of Cyclin A at the protein level, which
together with the quantification of the DNA content using fluorescence-activated
cell sorting (FACS) analysis indicated that the observed effects on cellular proliferation
may be due to changes in cell cycle. Further, we found testis-specific protein
kinase 1 (TESK1) kinase upregulation corresponding with phosphorylation and inactivation
of actin severing protein Cofilin, which could explain changes in the cytoskeleton
and cellular migration. These results indicate that endometriosis is associated
with LINC01133 upregulation, which may affect pathogenesis via the cellular proliferation
and migration pathways.

text: 'DivIVA is a protein initially identified as a spatial regulator of cell division
in the model organism Bacillus subtilis, but its homologues are present in many
other Gram-positive bacteria, including Clostridia species. Besides its role as
topological regulator of the Min system during bacterial cell division, DivIVA
is involved in chromosome segregation during sporulation, genetic competence,
and cell wall synthesis. DivIVA localizes to regions of high membrane curvature,
such as the cell poles and cell division site, where it recruits distinct binding
partners. Previously, it was suggested that negative curvature sensing is the
main mechanism by which DivIVA binds to these specific regions. Here, we show
that Clostridioides difficile DivIVA binds preferably to membranes containing
negatively charged phospholipids, especially cardiolipin. Strikingly, we observed
that upon binding, DivIVA modifies the lipid distribution and induces changes
to lipid bilayers containing cardiolipin. Our observations indicate that DivIVA
might play a more complex and so far unknown active role during the formation
of the cell division septal membrane. '

text: About eight million animal species are estimated to live on Earth, and all
except those belonging to one subphylum are invertebrates. Invertebrates are incredibly
diverse in their morphologies, life histories, and in the range of the ecological
niches that they occupy. A great variety of modes of reproduction and sex determination
systems is also observed among them, and their mosaic-distribution across the
phylogeny shows that transitions between them occur frequently and rapidly. Genetic
conflict in its various forms is a long-standing theory to explain what drives
those evolutionary transitions. Here, we review (1) the different modes of reproduction
among invertebrate species, highlighting sexual reproduction as the probable ancestral
state; (2) the paradoxical diversity of sex determination systems; (3) the different
types of genetic conflicts that could drive the evolution of such different systems.
