text: A high-resolution structure of trimeric cyanobacterial Photosystem I (PSI)
from Thermosynechococcus elongatus was reported as the first atomic model of PSI
almost 20 years ago. However, the monomeric PSI structure has not yet been reported
despite long-standing interest in its structure and extensive spectroscopic characterization
of the loss of red chlorophylls upon monomerization. Here, we describe the structure
of monomeric PSI from Thermosynechococcus elongatus BP-1. Comparison with the
trimer structure gave detailed insights into monomerization-induced changes in
both the central trimerization domain and the peripheral regions of the complex.
Monomerization-induced loss of red chlorophylls is assigned to a cluster of chlorophylls
adjacent to PsaX. Based on our findings, we propose a role of PsaX in the stabilization
of red chlorophylls and that lipids of the surrounding membrane present a major
source of thermal energy for uphill excitation energy transfer from red chlorophylls
to P700.

text: Plants develop new organs to adjust their bodies to dynamic changes in the
environment. How independent organs achieve anisotropic shapes and polarities
is poorly understood. To address this question, we constructed a mechano-biochemical
model for Arabidopsis root meristem growth that integrates biologically plausible
principles. Computer model simulations demonstrate how differential growth of
neighboring tissues results in the initial symmetry-breaking leading to anisotropic
root growth. Furthermore, the root growth feeds back on a polar transport network
of the growth regulator auxin. Model, predictions are in close agreement with
in vivo patterns of anisotropic growth, auxin distribution, and cell polarity,
as well as several root phenotypes caused by chemical, mechanical, or genetic
perturbations. Our study demonstrates that the combination of tissue mechanics
and polar auxin transport organizes anisotropic root growth and cell polarities
during organ outgrowth. Therefore, a mobile auxin signal transported through immobile
cells drives polarity and growth mechanics to coordinate complex organ development.

text: Turbulence generally arises in shear flows if velocities and hence, inertial
forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit
disordered motion even at vanishing inertia. Intermediate between these cases,
a state of chaotic motion, “elastoinertial turbulence” (EIT), has been observed
in a narrow Reynolds number interval. We here determine the origin of EIT in experiments
and show that characteristic EIT structures can be detected across an unexpectedly
wide range of parameters. Close to onset, a pattern of chevron-shaped streaks
emerges in qualitative agreement with linear and weakly nonlinear theory. However,
in experiments, the dynamics remain weakly chaotic, and the instability can be
traced to far lower Reynolds numbers than permitted by theory. For increasing
inertia, the flow undergoes a transformation to a wall mode composed of inclined
near-wall streaks and shear layers. This mode persists to what is known as the
“maximum drag reduction limit,” and overall EIT is found to dominate viscoelastic
flows across more than three orders of magnitude in Reynolds number.

text: 'Machines enabled the Industrial Revolution and are central to modern technological
progress: A machine’s parts transmit forces, motion, and energy to one another
in a predetermined manner. Today’s engineering frontier, building artificial micromachines
that emulate the biological machinery of living organisms, requires faithful assembly
and energy consumption at the microscale. Here, we demonstrate the programmable
assembly of active particles into autonomous metamachines using optical templates.
Metamachines, or machines made of machines, are stable, mobile and autonomous
architectures, whose dynamics stems from the geometry. We use the interplay between
anisotropic force generation of the active colloids with the control of their
orientation by local geometry. This allows autonomous reprogramming of active
particles of the metamachines to achieve multiple functions. It permits the modular
assembly of metamachines by fusion, reconfiguration of metamachines and, we anticipate,
a shift in focus of self-assembly towards active matter and reprogrammable materials.'

text: To survive elevated temperatures, ectotherms adjust the fluidity of membranes
by fine-tuning lipid desaturation levels in a process previously described to
be cell autonomous. We have discovered that, in Caenorhabditis elegans, neuronal
heat shock factor 1 (HSF-1), the conserved master regulator of the heat shock
response (HSR), causes extensive fat remodeling in peripheral tissues. These changes
include a decrease in fat desaturase and acid lipase expression in the intestine
and a global shift in the saturation levels of plasma membrane’s phospholipids.
The observed remodeling of plasma membrane is in line with ectothermic adaptive
responses and gives worms a cumulative advantage to warm temperatures. We have
determined that at least 6 TAX-2/TAX-4 cyclic guanosine monophosphate (cGMP) gated
channel expressing sensory neurons, and transforming growth factor ß (TGF-β)/bone
morphogenetic protein (BMP) are required for signaling across tissues to modulate
fat desaturation. We also find neuronal hsf-1 is not only sufficient but also
partially necessary to control the fat remodeling response and for survival at
warm temperatures. This is the first study to show that a thermostat-based mechanism
can cell nonautonomously coordinate membrane saturation and composition across
tissues in a multicellular animal.

text: Consider a random set of points on the unit sphere in ℝd, which can be either
uniformly sampled or a Poisson point process. Its convex hull is a random inscribed
polytope, whose boundary approximates the sphere. We focus on the case d = 3,
for which there are elementary proofs and fascinating formulas for metric properties.
In particular, we study the fraction of acute facets, the expected intrinsic volumes,
the total edge length, and the distance to a fixed point. Finally we generalize
the results to the ellipsoid with homeoid density.

text: Molecular chaperones are central to cellular protein homeostasis. Dynamic
disorder is a key feature of the complexes of molecular chaperones and their client
proteins, and it facilitates the client release towards a folded state or the
handover to downstream components. The dynamic nature also implies that a given
chaperone can interact with many different client proteins, based on physico-chemical
sequence properties rather than on structural complementarity of their (folded)
3D structure. Yet, the balance between this promiscuity and some degree of client
specificity is poorly understood. Here, we review recent atomic-level descriptions
of chaperones with client proteins, including chaperones in complex with intrinsically
disordered proteins, with membrane-protein precursors, or partially folded client
proteins. We focus hereby on chaperone-client interactions that are independent
of ATP. The picture emerging from these studies highlights the importance of dynamics
in these complexes, whereby several interaction types, not only hydrophobic ones,
contribute to the complex formation. We discuss these features of chaperone-client
complexes and possible factors that may contribute to this balance of promiscuity
and specificity.

text: Strigolactones (SLs) are carotenoid-derived plant hormones that control shoot
branching and communications between host plants and symbiotic fungi or root parasitic
plants. Extensive studies have identified the key components participating in
SL biosynthesis and signalling, whereas the catabolism or deactivation of endogenous
SLs in planta remains largely unknown. Here, we report that the Arabidopsis carboxylesterase
15 (AtCXE15) and its orthologues function as efficient hydrolases of SLs. We show
that overexpression of AtCXE15 promotes shoot branching by dampening SL-inhibited
axillary bud outgrowth. We further demonstrate that AtCXE15 could bind and efficiently
hydrolyse SLs both in vitro and in planta. We also provide evidence that AtCXE15
is capable of catalysing hydrolysis of diverse SL analogues and that such CXE15-dependent
catabolism of SLs is evolutionarily conserved in seed plants. These results disclose
a catalytic mechanism underlying homoeostatic regulation of SLs in plants, which
also provides a rational approach to spatial-temporally manipulate the endogenous
SLs and thus architecture of crops and ornamental plants.

text: To survive elevated temperatures, ectotherms adjust the fluidity of membranes
by fine-tuning lipid desaturation levels in a process previously described to
be cell-autonomous. We have discovered that, in Caenorhabditis elegans, neuronal
Heat shock Factor 1 (HSF-1), the conserved master regulator of the heat shock
response (HSR)- causes extensive fat remodelling in peripheral tissues. These
changes include a decrease in fat desaturase and acid lipase expression in the
intestine, and a global shift in the saturation levels of plasma membrane’s phospholipids.
The observed remodelling of plasma membrane is in line with ectothermic adaptive
responses and gives worms a cumulative advantage to warm temperatures. We have
determined that at least six TAX-2/TAX-4 cGMP gated channel expressing sensory
neurons and TGF-β/BMP are required for signalling across tissues to modulate fat
desaturation. We also find neuronal hsf-1 is not only sufficient but also partially
necessary to control the fat remodelling response and for survival at warm temperatures.
This is the first study to show that a thermostat-based mechanism can cell non-autonomously
coordinate membrane saturation and composition across tissues in a multicellular
animal.

text: Since the inception of Bitcoin, a plethora of distributed ledgers differing
in design and purpose has been created. While by design, blockchains provide no
means to securely communicate with external systems, numerous attempts towards
trustless cross-chain communication have been proposed over the years. Today,
cross-chain communication (CCC) plays a fundamental role in cryptocurrency exchanges,
scalability efforts via sharding, extension of existing systems through sidechains,
and bootstrapping of new blockchains. Unfortunately, existing proposals are designed
ad-hoc for specific use-cases, making it hard to gain confidence in their correctness
and composability. We provide the first systematic exposition of cross-chain communication
protocols. We formalize the underlying research problem and show that CCC is impossible
without a trusted third party, contrary to common beliefs in the blockchain community.
With this result in mind, we develop a framework to design new and evaluate existing
CCC protocols, focusing on the inherent trust assumptions thereof, and derive
a classification covering the field of cross-chain communication to date. We conclude
by discussing open challenges for CCC research and the implications of interoperability
on the security and privacy of blockchains.

text: Off-chain protocols (channels) are a promising solution to the scalability
and privacy challenges of blockchain payments. Current proposals, however, require
synchrony assumptions to preserve the safety of a channel, leaking to an adversary
the exact amount of time needed to control the network for a successful attack.
In this paper, we introduce Brick, the first payment channel that remains secure
under network asynchrony and concurrently provides correct incentives. The core
idea is to incorporate the conflict resolution process within the channel by introducing
a rational committee of external parties, called wardens. Hence, if a party wants
to close a channel unilaterally, it can only get the committee’s approval for
the last valid state. Additionally, Brick provides sub-second latency because
it does not employ heavy-weight consensus. Instead, Brick uses consistent broadcast
to announce updates and close the channel, a light-weight abstraction that is
powerful enough to preserve safety and liveness to any rational parties. We formally
define and prove for Brick the properties a payment channel construction should
fulfill. We also design incentives for Brick such that honest and rational behavior
aligns. Finally, we provide a reference implementation of the smart contracts
in Solidity.

text: Erythropoietin enhances oxygen delivery and reduces hypoxia-induced cell death,
but its pro-thrombotic activity is problematic for use of erythropoietin in treating
hypoxia. We constructed a fusion protein that stimulates red blood cell production
and neuroprotection without triggering platelet production, a marker for thrombosis.
The protein consists of an anti-glycophorin A nanobody and an erythropoietin mutant
(L108A). The mutation reduces activation of erythropoietin receptor homodimers
that induce erythropoiesis and thrombosis, but maintains the tissue-protective
signaling. The binding of the nanobody element to glycophorin A rescues homodimeric
erythropoietin receptor activation on red blood cell precursors. In a cell proliferation
assay, the fusion protein is active at 10−14 M, allowing an estimate of the number
of receptor–ligand complexes needed for signaling. This fusion protein stimulates
erythroid cell proliferation in vitro and in mice, and shows neuroprotective activity
in vitro. Our erythropoietin fusion protein presents a novel molecule for treating
hypoxia.

text: Branching morphogenesis governs the formation of many organs such as lung,
kidney, and the neurovascular system. Many studies have explored system-specific
molecular and cellular regulatory mechanisms, as well as self-organizing rules
underlying branching morphogenesis. However, in addition to local cues, branched
tissue growth can also be influenced by global guidance. Here, we develop a theoretical
framework for a stochastic self-organized branching process in the presence of
external cues. Combining analytical theory with numerical simulations, we predict
differential signatures of global vs. local regulatory mechanisms on the branching
pattern, such as angle distributions, domain size, and space-filling efficiency.
We find that branch alignment follows a generic scaling law determined by the
strength of global guidance, while local interactions influence the tissue density
but not its overall territory. Finally, using zebrafish innervation as a model
system, we test these key features of the model experimentally. Our work thus
provides quantitative predictions to disentangle the role of different types of
cues in shaping branched structures across scales.

text: Digital hardware Trojans are integrated circuits whose implementation differ
from the specification in an arbitrary and malicious way. For example, the circuit
can differ from its specified input/output behavior after some fixed number of
queries (known as “time bombs”) or on some particular input (known as “cheat codes”).
To detect such Trojans, countermeasures using multiparty computation (MPC) or
verifiable computation (VC) have been proposed. On a high level, to realize a
circuit with specification F one has more sophisticated circuits F⋄ manufactured
(where F⋄ specifies a MPC or VC of F ), and then embeds these F⋄ ’s into
a master circuit which must be trusted but is relatively simple compared to F
. Those solutions impose a significant overhead as F⋄ is much more complex
than F , also the master circuits are not exactly trivial. In this work, we
show that in restricted settings, where F has no evolving state and is queried
on independent inputs, we can achieve a relaxed security notion using very simple
constructions. In particular, we do not change the specification of the circuit
at all (i.e., F=F⋄ ). Moreover the master circuit basically just queries a subset
of its manufactured circuits and checks if they’re all the same. The security
we achieve guarantees that, if the manufactured circuits are initially tested
on up to T inputs, the master circuit will catch Trojans that try to deviate on
significantly more than a 1/T fraction of the inputs. This bound is optimal for
the type of construction considered, and we provably achieve it using a construction
where 12 instantiations of F need to be embedded into the master. We also discuss
an extremely simple construction with just 2 instantiations for which we conjecture
that it already achieves the optimal bound.

text: Synaptic transmission, connectivity, and dendritic morphology mature in parallel
during brain development and are often disrupted in neurodevelopmental disorders.
Yet how these changes influence the neuronal computations necessary for normal
brain function are not well understood. To identify cellular mechanisms underlying
the maturation of synaptic integration in interneurons, we combined patch-clamp
recordings of excitatory inputs in mouse cerebellar stellate cells (SCs), three-dimensional
reconstruction of SC morphology with excitatory synapse location, and biophysical
modeling. We found that postnatal maturation of postsynaptic strength was homogeneously
reduced along the somatodendritic axis, but dendritic integration was always sublinear.
However, dendritic branching increased without changes in synapse density, leading
to a substantial gain in distal inputs. Thus, changes in synapse distribution,
rather than dendrite cable properties, are the dominant mechanism underlying the
maturation of neuronal computation. These mechanisms favor the emergence of a
spatially compartmentalized two-stage integration model promoting location-dependent
integration within dendritic subunits.

text: Theoretical and experimental studies of the interaction between spins and
temperature are vital for the development of spin caloritronics, as they dictate
the design of future devices. In this work, we propose a two-terminal cold-atom
simulator to study that interaction. The proposed quantum simulator consists of
strongly interacting atoms that occupy two temperature reservoirs connected by
a one-dimensional link. First, we argue that the dynamics in the link can be described
using an inhomogeneous Heisenberg spin chain whose couplings are defined by the
local temperature. Second, we show the existence of a spin current in a system
with a temperature difference by studying the dynamics that follows the spin-flip
of an atom in the link. A temperature gradient accelerates the impurity in one
direction more than in the other, leading to an overall spin current similar to
the spin Seebeck effect.

text: While convolutional neural networks (CNNs) have found wide adoption as state-of-the-art
models for image-related tasks, their predictions are often highly sensitive to
small input perturbations, which the human vision is robust against. This paper
presents Perturber, a web-based application that allows users to instantaneously
explore how CNN activations and predictions evolve when a 3D input scene is interactively
perturbed. Perturber offers a large variety of scene modifications, such as camera
controls, lighting and shading effects, background modifications, object morphing,
as well as adversarial attacks, to facilitate the discovery of potential vulnerabilities.
Fine-tuned model versions can be directly compared for qualitative evaluation
of their robustness. Case studies with machine learning experts have shown that
Perturber helps users to quickly generate hypotheses about model vulnerabilities
and to qualitatively compare model behavior. Using quantitative analyses, we could
replicate users’ insights with other CNN architectures and input images, yielding
new insights about the vulnerability of adversarially trained models.

text: Multicellular organisms develop complex shapes from much simpler, single-celled
zygotes through a process commonly called morphogenesis. Morphogenesis involves
an interplay between several factors, ranging from the gene regulatory networks
determining cell fate and differentiation to the mechanical processes underlying
cell and tissue shape changes. Thus, the study of morphogenesis has historically
been based on multidisciplinary approaches at the interface of biology with physics
and mathematics. Recent technological advances have further improved our ability
to study morphogenesis by bridging the gap between the genetic and biophysical
factors through the development of new tools for visualizing, analyzing, and perturbing
these factors and their biochemical intermediaries. Here, we review how a combination
of genetic, microscopic, biophysical, and biochemical approaches has aided our
attempts to understand morphogenesis and discuss potential approaches that may
be beneficial to such an inquiry in the future.

text: 'Key trees are often the best solution in terms of transmission cost and storage
requirements for managing keys in a setting where a group needs to share a secret
key, while being able to efficiently rotate the key material of users (in order
to recover from a potential compromise, or to add or remove users). Applications
include multicast encryption protocols like LKH (Logical Key Hierarchies) or group
messaging like the current IETF proposal TreeKEM. A key tree is a (typically balanced)
binary tree, where each node is identified with a key: leaf nodes hold users’
secret keys while the root is the shared group key. For a group of size N, each
user just holds log(N) keys (the keys on the path from its leaf to the root)
and its entire key material can be rotated by broadcasting 2log(N) ciphertexts
(encrypting each fresh key on the path under the keys of its parents). In this
work we consider the natural setting where we have many groups with partially
overlapping sets of users, and ask if we can find solutions where the cost of
rotating a key is better than in the trivial one where we have a separate key
tree for each group. We show that in an asymptotic setting (where the number m
of groups is fixed while the number N of users grows) there exist more general
key graphs whose cost converges to the cost of a single group, thus saving a factor
linear in the number of groups over the trivial solution. As our asymptotic “solution”
converges very slowly and performs poorly on concrete examples, we propose an
algorithm that uses a natural heuristic to compute a key graph for any given group
structure. Our algorithm combines two greedy algorithms, and is thus very efficient:
it first converts the group structure into a “lattice graph”, which is then turned
into a key graph by repeatedly applying the algorithm for constructing a Huffman
code. To better understand how far our proposal is from an optimal solution, we
prove lower bounds on the update cost of continuous group-key agreement and multicast
encryption in a symbolic model admitting (asymmetric) encryption, pseudorandom
generators, and secret sharing as building blocks.'

text: We show that in a two-dimensional electron gas with an annular Fermi surface,
long-range Coulomb interactions can lead to unconventional superconductivity by
the Kohn-Luttinger mechanism. Superconductivity is strongly enhanced when the
inner and outer Fermi surfaces are close to each other. The most prevalent state
has chiral p-wave symmetry, but d-wave and extended s-wave pairing are also possible.
We discuss these results in the context of rhombohedral trilayer graphene, where
superconductivity was recently discovered in regimes where the normal state has
an annular Fermi surface. Using realistic parameters, our mechanism can account
for the order of magnitude of Tc, as well as its trends as a function of electron
density and perpendicular displacement field. Moreover, it naturally explains
some of the outstanding puzzles in this material, that include the weak temperature
dependence of the resistivity above Tc, and the proximity of spin singlet superconductivity
to the ferromagnetic phase.

text: For many years, fullerene derivatives have been the main n-type material of
organic electronics and optoelectronics. Recently, fullerene derivatives functionalized
with ethylene glycol (EG) side chains have been showing important properties such
as enhanced dielectric constants, facile doping and enhanced self-assembly capabilities.
Here, we have prepared field-effect transistors using a series of these fullerene
derivatives equipped with EG side chains of different lengths. Transport data
show the beneficial effect of increasing the EG side chain. In order to understand
the material properties, full structural determination of these fullerene derivatives
has been achieved by coupling the X-ray data with molecular dynamics (MD) simulations.
The increase in transport properties is paired with the formation of extended
layered structures, efficient molecular packing and an increase in the crystallite
alignment. The layer-like structure is composed of conducting layers, containing
of closely packed C60 balls approaching the inter-distance of 1 nm, that are separated
by well-defined EG layers, where the EG chains are rather splayed with the chain
direction almost perpendicular to the layer normal. Such a layered structure appears
highly ordered and highly aligned with the C60 planes oriented parallel to the
substrate in the thin film configuration. The order inside the thin film increases
with the EG chain length, allowing the systems to achieve mobilities as high as
0.053 cm2 V−1 s−1. Our work elucidates the structure of these interesting semiconducting
organic molecules and shows that the synergistic use of X-ray structural analysis
and MD simulations is a powerful tool to identify the structure of thin organic
films for optoelectronic applications.

text: Flowering plants utilize small RNA molecules to guide DNA methyltransferases
to genomic sequences. This RNA-directed DNA methylation (RdDM) pathway preferentially
targets euchromatic transposable elements. However, RdDM is thought to be recruited
by methylation of histone H3 at lysine 9 (H3K9me), a hallmark of heterochromatin.
How RdDM is targeted to euchromatin despite an affinity for H3K9me is unclear.
Here we show that loss of histone H1 enhances heterochromatic RdDM, preferentially
at nucleosome linker DNA. Surprisingly, this does not require SHH1, the RdDM component
that binds H3K9me. Furthermore, H3K9me is dispensable for RdDM, as is CG DNA methylation.
Instead, we find that non-CG methylation is specifically associated with small
RNA biogenesis, and without H1 small RNA production quantitatively expands to
non-CG methylated loci. Our results demonstrate that H1 enforces the separation
of euchromatic and heterochromatic DNA methylation pathways by excluding the small
RNA-generating branch of RdDM from non-CG methylated heterochromatin.

text: TGFβ overexpression is commonly detected in cancer patients and correlates
with poor prognosis and metastasis. Cancer progression is often associated with
an enhanced recruitment of myeloid-derived cells to the tumor microenvironment.
Here we show that functional TGFβ-signaling in myeloid cells is required for metastasis
to the lungs and the liver. Myeloid-specific deletion of Tgfbr2 resulted in reduced
spontaneous lung metastasis, which was associated with a reduction of proinflammatory
cytokines in the metastatic microenvironment. Notably, CD8+ T cell depletion in
myeloid-specific Tgfbr2-deficient mice rescued lung metastasis. Myeloid-specific
Tgfbr2-deficiency resulted in reduced liver metastasis with an almost complete
absence of myeloid cells within metastatic foci. On contrary, an accumulation
of Tgfβ-responsive myeloid cells was associated with an increased recruitment
of monocytes and granulocytes and higher proinflammatory cytokine levels in control
mice. Monocytic cells isolated from metastatic livers of Tgfbr2-deficient mice
showed increased polarization towards the M1 phenotype, Tnfα and Il-1β expression,
reduced levels of M2 markers and reduced production of chemokines responsible
for myeloid-cell recruitment. No significant differences in Tgfβ levels were observed
at metastatic sites of any model. These data demonstrate that Tgfβ signaling in
monocytic myeloid cells suppresses CD8+ T cell activity during lung metastasis,
while these cells actively contribute to tumor growth during liver metastasis.
Thus, myeloid cells modulate metastasis through different mechanisms in a tissue-specific
manner.

text: We consider the quantum many-body evolution of a homogeneous Fermi gas in
three dimensions in the coupled semiclassical and mean-field scaling regime. We
study a class of initial data describing collective particle–hole pair excitations

that the many-body evolution can be approximated in Fock space norm by a quasi-free
bosonic evolution of the collective particle–hole excitations.

text: We derive optimal-order homogenization rates for random nonlinear elliptic
PDEs with monotone nonlinearity in the uniformly elliptic case. More precisely,
for a random monotone operator on \mathbb {R}^d with stationary law (that is spatially
homogeneous statistics) and fast decay of correlations on scales larger than the
microscale \varepsilon >0, we establish homogenization error estimates of the
order \varepsilon in case d\geqq 3, and of the order \varepsilon |\log \varepsilon
|^{1/2} in case d=2. Previous results in nonlinear stochastic homogenization have
been limited to a small algebraic rate of convergence \varepsilon ^\delta . We
also establish error estimates for the approximation of the homogenized operator
by the method of representative volumes of the order (L/\varepsilon )^{-d/2} for
a representative volume of size L. Our results also hold in the case of systems
for which a (small-scale) C^{1,\alpha } regularity theory is available.

text: We show that Yao’s garbling scheme is adaptively indistinguishable for the
class of Boolean circuits of size S and treewidth w with only a SO(w) loss
in security. For instance, circuits with constant treewidth are as a result adaptively
indistinguishable with only a polynomial loss. This (partially) complements a
negative result of Applebaum et al. (Crypto 2013), which showed (assuming one-way
functions) that Yao’s garbling scheme cannot be adaptively simulatable. As main
technical contributions, we introduce a new pebble game that abstracts out our
security reduction and then present a pebbling strategy for this game where the
number of pebbles used is roughly O(δwlog(S)) , δ being the fan-out of the
circuit. The design of the strategy relies on separators, a graph-theoretic notion
with connections to circuit complexity. with only a SO(w) loss in security.

text: Classical models with complex energy landscapes represent a perspective avenue
for the near-term application of quantum simulators. Until now, many theoretical
works studied the performance of quantum algorithms for models with a unique ground
state. However, when the classical problem is in a so-called clustering phase,
the ground state manifold is highly degenerate. As an example, we consider a 3-XORSAT
model defined on simple hypergraphs. The degeneracy of classical ground state
manifold translates into the emergence of an extensive number of Z2 symmetries,
which remain intact even in the presence of a quantum transverse magnetic field.
We establish a general duality approach that restricts the quantum problem to
a given sector of conserved Z2 charges and use it to study how the outcome of
the quantum adiabatic algorithm depends on the hypergraph geometry. We show that
the tree hypergraph which corresponds to a classically solvable instance of the
3-XORSAT problem features a constant gap, whereas the closed hypergraph encounters
a second-order phase transition with a gap vanishing as a power-law in the problem
size. The duality developed in this work provides a practical tool for studies
of quantum models with classically degenerate energy manifold and reveals potential
connections between glasses and gauge theories.

text: 'We present DAG-Rider, the first asynchronous Byzantine Atomic Broadcast protocol
that achieves optimal resilience, optimal amortized communication complexity,
and optimal time complexity. DAG-Rider is post-quantum safe and ensures that all
values proposed by correct processes eventually get delivered. We construct DAG-Rider
in two layers: In the first layer, processes reliably broadcast their proposals
and build a structured Directed Acyclic Graph (DAG) of the communication among
them. In the second layer, processes locally observe their DAGs and totally order
all proposals with no extra communication.'

text: Genetic adaptation and phenotypic plasticity facilitate the migration into
new habitats and enable organisms to cope with a rapidly changing environment.
In contrast to genetic adaptation that spans multiple generations as an evolutionary
process, phenotypic plasticity allows acclimation within the life-time of an organism.
Genetic adaptation and phenotypic plasticity are usually studied in isolation,
however, only by including their interactive impact, we can understand acclimation
and adaptation in nature. We aimed to explore the contribution of adaptation and
plasticity in coping with an abiotic (salinity) and a biotic (Vibrio bacteria)
stressor using six different populations of the broad-nosed pipefish Syngnathus
typhle that originated from either high [14–17 Practical Salinity Unit (PSU)]
or low (7–11 PSU) saline environments along the German coastline of the Baltic
Sea. We exposed wild caught animals, to either high (15 PSU) or low (7 PSU) salinity,
representing native and novel salinity conditions and allowed animals to mate.
After male pregnancy, offspring was split and each half was exposed to one of
the two salinities and infected with Vibrio alginolyticus bacteria that were evolved
at either of the two salinities in a fully reciprocal design. We investigated
life-history traits of fathers and expression of 47 target genes in mothers and
offspring. Pregnant males originating from high salinity exposed to low salinity
were highly susceptible to opportunistic fungi infections resulting in decreased
offspring size and number. In contrast, no signs of fungal infection were identified
in fathers originating from low saline conditions suggesting that genetic adaptation
has the potential to overcome the challenges encountered at low salinity. Offspring
from parents with low saline origin survived better at low salinity suggesting
genetic adaptation to low salinity. In addition, gene expression analyses of juveniles
indicated patterns of local adaptation, trans-generational plasticity and developmental
plasticity. In conclusion, our study suggests that pipefish are locally adapted
to the low salinity in their environment, however, they are retaining phenotypic
plasticity, which allows them to also cope with ancestral salinity levels and
prevailing pathogens.

text: A facile approach for developing an interfacial solar evaporator by heat localization
of solar-thermal energy conversion at water-air liquid composed by in-situ polymerization
of Fe2O3 nanoparticles (Fe2O3@PPy) deposited over a facial sponge is proposed.
The demonstrated system consists of a floating solar receiver having a vertically
cross-linked microchannel for wicking up saline water. The in situ polymerized
Fe2O3@PPy interfacial layer promotes diffuse reflection and its rough black surface
allows Omni-directional solar absorption (94%) and facilitates efficient thermal
localization at the water/air interface and offers a defect-rich surface to promote
heat localization (41.9 °C) and excellent thermal management due to cellulosic
content. The self-floating composite foam reveals continuous vapors generation
at a rate of 1.52 kg m−2 h−1 under one 1 kW m−2 and profound evaporating efficiency
(95%) without heat losses that dissipates in its surroundings. Indeed, long-term
evaporation experiments reveal the negligible disparity in continuous evaporation
rate (33.84 kg m−2/8.3 h) receiving two sun solar intensity, and ensures the stability
of the device under intense seawater conditions synchronized with excellent salt
rejection potential. More importantly, Raman spectroscopy investigation validates
the orange dye rejection via Fe2O3@PPy solar evaporator. The combined advantages
of high efficiency, self-floating capability, multimedia rejection, low cost,
and this configuration are promising for producing large-scale solar steam generating
systems appropriate for commercial clean water yield due to their scalable fabrication.

text: 'For animals to survive until reproduction, it is crucial that juveniles successfully
detect potential predators and respond with appropriate behavior. The recognition
of cues originating from predators can be innate or learned. Cues of various modalities
might be used alone or in multi-modal combinations to detect and distinguish predators
but studies investigating multi-modal integration in predator avoidance are scarce.
Here, we used wild, naive tadpoles of the Neotropical poison frog Allobates femoralis
( Boulenger, 1884) to test their reaction to cues with two modalities from two
different sympatrically occurring potential predators: heterospecific predatory
Dendrobates tinctorius tadpoles and dragonfly larvae. We presented A. femoralis
tadpoles with olfactory or visual cues, or a combination of the two, and compared
their reaction to a water control in a between-individual design. In our trials,
A. femoralis tadpoles reacted to multi-modal stimuli (a combination of visual
and chemical information) originating from dragonfly larvae with avoidance but
showed no reaction to uni-modal cues or cues from heterospecific tadpoles. In
addition, visual cues from conspecifics increased swimming activity while cues
from predators had no effect on tadpole activity. Our results show that A. femoralis
tadpoles can innately recognize some predators and probably need both visual and
chemical information to effectively avoid them. This is the first study looking
at anti-predator behavior in poison frog tadpoles. We discuss how parental care
might influence the expression of predator avoidance responses in tadpoles.'

text: The choice of the boundary conditions in mechanical problems has to reflect
the interaction of the considered material with the surface. Still the assumption
of the no-slip condition is preferred in order to avoid boundary terms in the
analysis and slipping effects are usually overlooked. Besides the “static slip
models”, there are phenomena that are not accurately described by them, e.g. at
the moment when the slip changes rapidly, the wall shear stress and the slip can
exhibit a sudden overshoot and subsequent relaxation. When these effects become
significant, the so-called dynamic slip phenomenon occurs. We develop a mathematical
analysis of Navier–Stokes-like problems with a dynamic slip boundary condition,
which requires a proper generalization of the Gelfand triplet and the corresponding
function space setting.

text: 'The understanding of material appearance perception is a complex problem
due to interactions between material reflectance, surface geometry, and illumination.
Recently, Serrano et al. collected the largest dataset to date with subjective
ratings of material appearance attributes, including glossiness, metallicness,
sharpness and contrast of reflections. In this work, we make use of their dataset
to investigate for the first time the impact of the interactions between illumination,
geometry, and eight different material categories in perceived appearance attributes.
After an initial analysis, we select for further analysis the four material categories
that cover the largest range for all perceptual attributes: fabric, plastic, ceramic,
and metal. Using a cumulative link mixed model (CLMM) for robust regression, we
discover interactions between these material categories and four representative
illuminations and object geometries. We believe that our findings contribute to
expanding the knowledge on material appearance perception and can be useful for
many applications, such as scene design, where any particular material in a given
shape can be aligned with dominant classes of illumination, so that a desired
strength of appearance attributes can be achieved.'

text: How tissues acquire complex shapes is a fundamental question in biology and
regenerative medicine. Zebrafish semicircular canals form from invaginations in
the otic epithelium (buds) that extend and fuse to form the hubs of each canal.
We find that conventional actomyosin-driven behaviors are not required. Instead,
local secretion of hyaluronan, made by the enzymes uridine 5′-diphosphate dehydrogenase
(ugdh) and hyaluronan synthase 3 (has3), drives canal morphogenesis. Charged hyaluronate
polymers osmotically swell with water and generate isotropic extracellular pressure
to deform the overlying epithelium into buds. The mechanical anisotropy needed
to shape buds into tubes is conferred by a polarized distribution of actomyosin
and E-cadherin-rich membrane tethers, which we term cytocinches. Most work on
tissue morphogenesis ascribes actomyosin contractility as the driving force, while
the extracellular matrix shapes tissues through differential stiffness. Our work
inverts this expectation. Hyaluronate pressure shaped by anisotropic tissue stiffness
may be a widespread mechanism for powering morphological change in organogenesis
and tissue engineering.

text: 'In two-player games on graphs, the players move a token through a graph to
produce an infinite path, which determines the winner of the game. Such games
are central in formal methods since they model the interaction between a non-terminating
system and its environment. In bidding games the players bid for the right to
move the token: in each round, the players simultaneously submit bids, and the
higher bidder moves the token and pays the other player. Bidding games are known
to have a clean and elegant mathematical structure that relies on the ability
of the players to submit arbitrarily small bids. Many applications, however, require
a fixed granularity for the bids, which can represent, for example, the monetary
value expressed in cents. We study, for the first time, the combination of discrete-bidding
and infinite-duration games. Our most important result proves that these games
form a large determined subclass of concurrent games, where determinacy is the
strong property that there always exists exactly one player who can guarantee
winning the game. In particular, we show that, in contrast to non-discrete bidding
games, the mechanism with which tied bids are resolved plays an important role
in discrete-bidding games. We study several natural tie-breaking mechanisms and
show that, while some do not admit determinacy, most natural mechanisms imply
determinacy for every pair of initial budgets.'

text: "We study Multi-party computation (MPC) in the setting of subversion, where
the adversary tampers with the machines of honest parties. Our goal is to construct
actively secure MPC protocols where parties are corrupted adaptively by an adversary
(as in the standard adaptive security setting), and in addition, honest parties’
machines are compromised.\r\nThe idea of reverse firewalls (RF) was introduced
at EUROCRYPT’15 by Mironov and Stephens-Davidowitz as an approach to protecting
protocols against corruption of honest parties’ devices. Intuitively, an RF for
a party P is an external entity that sits between P and the outside world
and whose scope is to sanitize P ’s incoming and outgoing messages in the face
of subversion of their computer. Mironov and Stephens-Davidowitz constructed a
protocol for passively-secure two-party computation. At CRYPTO’20, Chakraborty,
Dziembowski and Nielsen constructed a protocol for secure computation with firewalls
that improved on this result, both by extending it to multi-party computation
protocol, and considering active security in the presence of static corruptions.
In this paper, we initiate the study of RF for MPC in the adaptive setting. We
put forward a definition for adaptively secure MPC in the reverse firewall setting,
explore relationships among the security notions, and then construct reverse firewalls
for MPC in this stronger setting of adaptive security. We also resolve the open
question of Chakraborty, Dziembowski and Nielsen by removing the need for a trusted
setup in constructing RF for MPC. Towards this end, we construct reverse firewalls
for adaptively secure augmented coin tossing and adaptively secure zero-knowledge
protocols and obtain a constant round adaptively secure MPC protocol in the reverse
firewall setting without setup. Along the way, we propose a new multi-party adaptively
secure coin tossing protocol in the plain model, that is of independent interest."

text: Cell division orientation is thought to result from a competition between
cell geometry and polarity domains controlling the position of the mitotic spindle
during mitosis. Depending on the level of cell shape anisotropy or the strength
of the polarity domain, one dominates the other and determines the orientation
of the spindle. Whether and how such competition is also at work to determine
unequal cell division (UCD), producing daughter cells of different size, remains
unclear. Here, we show that cell geometry and polarity domains cooperate, rather
than compete, in positioning the cleavage plane during UCDs in early ascidian
embryos. We found that the UCDs and their orientation at the ascidian third cleavage
rely on the spindle tilting in an anisotropic cell shape, and cortical polarity
domains exerting different effects on spindle astral microtubules. By systematically
varying mitotic cell shape, we could modulate the effect of attractive and repulsive
polarity domains and consequently generate predicted daughter cell size asymmetries
and position. We therefore propose that the spindle position during UCD is set
by the combined activities of cell geometry and polarity domains, where cell geometry
modulates the effect of cortical polarity domain(s).

text: The evidence linking innate immunity mechanisms and neurodegenerative diseases
is growing, but the specific mechanisms are incompletely understood. Experimental
data suggest that microglial TLR4 mediates the uptake and clearance of α-synuclein
also termed synucleinophagy. The accumulation of misfolded α-synuclein throughout
the brain is central to Parkinson's disease (PD). The distribution and progression
of the pathology is often attributed to the propagation of α-synuclein. Here,
we apply a classical α-synuclein propagation model of prodromal PD in wild type
and TLR4 deficient mice to study the role of TLR4 in the progression of the disease.
Our data suggest that TLR4 deficiency facilitates the α-synuclein seed spreading
associated with reduced lysosomal activity of microglia. Three months after seed
inoculation, more pronounced proteinase K-resistant α-synuclein inclusion pathology
is observed in mice with TLR4 deficiency. The facilitated propagation of α-synuclein
is associated with early loss of dopamine transporter (DAT) signal in the striatum
and loss of dopaminergic neurons in substantia nigra pars compacta of TLR4 deficient
mice. These new results support TLR4 signaling as a putative target for disease
modification to slow the progression of PD and related disorders.

text: The surface states of 3D topological insulators in general have negligible
quantum oscillations (QOs) when the chemical potential is tuned to the Dirac points.
In contrast, we find that topological Kondo insulators (TKIs) can support surface
states with an arbitrarily large Fermi surface (FS) when the chemical potential
is pinned to the Dirac point. We illustrate that these FSs give rise to finite-frequency
QOs, which can become comparable to the extremal area of the unhybridized bulk
bands. We show that this occurs when the crystal symmetry is lowered from cubic
to tetragonal in a minimal two-orbital model. We label such surface modes as 'shadow
surface states'. Moreover, we show that the sufficient next-nearest neighbor out-of-plane
hybridization leading to shadow surface states can be self-consistently stabilized
for tetragonal TKIs. Consequently, shadow surface states provide an important
example of high-frequency QOs beyond the context of cubic TKIs.

text: We combine experimental and theoretical approaches to explore excited rotational
states of molecules embedded in helium nanodroplets using CS2 and I2 as examples.
Laser-induced nonadiabatic molecular alignment is employed to measure spectral
lines for rotational states extending beyond those initially populated at the
0.37 K droplet temperature. We construct a simple quantum-mechanical model, based
on a linear rotor coupled to a single-mode bosonic bath, to determine the rotational
energy structure in its entirety. The calculated and measured spectral lines are
in good agreement. We show that the effect of the surrounding superfluid on molecular
rotation can be rationalized by a single quantity, the angular momentum, transferred
from the molecule to the droplet.

text: Adversarial training is an effective method to train deep learning models
that are resilient to norm-bounded perturbations, with the cost of nominal performance
drop. While adversarial training appears to enhance the robustness and safety
of a deep model deployed in open-world decision-critical applications, counterintuitively,
it induces undesired behaviors in robot learning settings. In this paper, we show
theoretically and experimentally that neural controllers obtained via adversarial
training are subjected to three types of defects, namely transient, systematic,
and conditional errors. We first generalize adversarial training to a safety-domain
optimization scheme allowing for more generic specifications. We then prove that
such a learning process tends to cause certain error profiles. We support our
theoretical results by a thorough experimental safety analysis in a robot-learning
task. Our results suggest that adversarial training is not yet ready for robot
learning.

text: In this paper, we investigate the distribution of the maximum of partial sums
of families of m -periodic complex-valued functions satisfying certain conditions.
We obtain precise uniform estimates for the distribution function of this maximum
in a near-optimal range. Our results apply to partial sums of Kloosterman sums
and other families of ℓ -adic trace functions, and are as strong as those obtained
by Bober, Goldmakher, Granville and Koukoulopoulos for character sums. In particular,
we improve on the recent work of the third author for Birch sums. However, unlike
character sums, we are able to construct families of m -periodic complex-valued
functions which satisfy our conditions, but for which the Pólya–Vinogradov inequality
is sharp.

text: Thermoelectric materials are engines that convert heat into an electrical
current. Intuitively, the efficiency of this process depends on how many electrons
(charge carriers) can move and how easily they do so, how much energy those moving
electrons transport, and how easily the temperature gradient is maintained. In
terms of material properties, an excellent thermoelectric material requires a
high electrical conductivity σ, a high Seebeck coefficient S (a measure of the
induced thermoelectric voltage as a function of temperature gradient), and a low
thermal conductivity κ. The challenge is that these three properties are strongly
interrelated in a conflicting manner (1). On page 722 of this issue, Roychowdhury
et al. (2) have found a way to partially break these ties in silver antimony telluride
(AgSbTe2) with the addition of cadmium (Cd) cations, which increase the ordering
in this inherently disordered thermoelectric material.

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: 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: "We present a deterministic O(log log log n)-round low-space Massively Parallel
Computation (MPC) algorithm for the classical problem of (Δ+1)-coloring on n-vertex
graphs. In this model, every machine has sublinear local space of size n^φ for
any arbitrary constant φ \\in (0,1). Our algorithm works under the relaxed setting
where each machine is allowed to perform exponential local computations, while
respecting the n^φ space and bandwidth limitations.\r\n\r\nOur key technical contribution
is a novel derandomization of the ingenious (Δ+1)-coloring local algorithm by
Chang-Li-Pettie (STOC 2018, SIAM J. Comput. 2020). The Chang-Li-Pettie algorithm
runs in T_local =poly(loglog n) rounds, which sets the state-of-the-art randomized
round complexity for the problem in the local model. Our derandomization employs
a combination of tools, notably pseudorandom generators (PRG) and bounded-independence
hash functions.\r\n\r\nThe achieved round complexity of O(logloglog n) rounds
matches the bound of log(T_local ), which currently serves an upper bound barrier
for all known randomized algorithms for locally-checkable problems in this model.
Furthermore, no deterministic sublogarithmic low-space MPC algorithms for the
(Δ+1)-coloring problem have been known before."

text: "In this paper, we study the power and limitations of component-stable algorithms
in the low-space model of Massively Parallel Computation (MPC). Recently Ghaffari,
Kuhn and Uitto (FOCS 2019) introduced the class of component-stable low-space
MPC algorithms, which are, informally, defined as algorithms for which the outputs
reported by the nodes in different connected components are required to be independent.
This very natural notion was introduced to capture most (if not all) of the known
efficient MPC algorithms to date, and it was the first general class of MPC algorithms
for which one can show non-trivial conditional lower bounds. In this paper we
enhance the framework of component-stable algorithms and investigate its effect
on the complexity of randomized and deterministic low-space MPC. Our key contributions
include: 1) We revise and formalize the lifting approach of Ghaffari, Kuhn and
Uitto. This requires a very delicate amendment of the notion of component stability,
which allows us to fill in gaps in the earlier arguments. 2) We also extend the
framework to obtain conditional lower bounds for deterministic algorithms and
fine-grained lower bounds that depend on the maximum degree Δ. 3) We demonstrate
a collection of natural graph problems for which non-component-stable algorithms
break the conditional lower bound obtained for component-stable algorithms. This
implies that, for both deterministic and randomized algorithms, component-stable
algorithms are conditionally weaker than the non-component-stable ones.\r\n\r\nAltogether
our results imply that component-stability might limit the computational power
of the low-space MPC model, paving the way for improved upper bounds that escape
the conditional lower bound setting of Ghaffari, Kuhn, and Uitto."

the deficiency spaces for this case was asserted already in Ibort et al. [Boundary

text: We derive rigorously the leading order of the correlation energy of a Fermi
gas in a scaling regime of high density and weak interaction. The result verifies
the prediction of the random-phase approximation. Our proof refines the method
of collective bosonization in three dimensions. We approximately diagonalize an
effective Hamiltonian describing approximately bosonic collective excitations
around the Hartree–Fock state, while showing that gapless and non-collective excitations
have only a negligible effect on the ground state energy.

text: While most simulations of the epoch of reionization have focused on single-stellar
populations in star-forming dwarf galaxies, products of binary evolution are expected
to significantly contribute to emissions of hydrogen-ionizing photons. Among these
products are stripped stars (or helium stars), which have their envelopes stripped
from interactions with binary companions, leaving an exposed helium core. Previous
work has suggested these stripped stars can dominate the Lyman Continuum (LyC)
photon output of high-redshift, low-luminosity galaxies post-starburst. Other
sources of hard radiation in the early universe include zero-metallicity Population
iii stars, which may have similar spectral energy distribution (SED) properties
to galaxies with radiation dominated by stripped-star emissions. Here, we use
four metrics (the power-law exponent over wavelength intervals 240–500 Å, 600–900
Å, and 1200–2000 Å, and the ratio of total luminosity in FUV wavelengths to LyC
wavelengths) to compare the SEDs of simulated galaxies with only single-stellar
evolution, galaxies containing stripped stars, and galaxies containing Population
iii stars, with four different initial mass functions (IMFs). We find that stripped
stars significantly alter SEDs in the LyC range of galaxies at the epoch of reionization.
SEDs in galaxies with stripped stars have lower power-law indices in the LyC range
and lower FUV to LyC luminosity ratios. These differences in SEDs are present
at all considered luminosities (${M}_{\mathrm{UV}}\gt -15$, AB system), and are
most pronounced for lower-luminosity galaxies. Intrinsic SEDs as well as those
with interstellar medium absorption of galaxies with stripped stars and Population
iii stars are found to be distinct for all tested Population iii IMFs.

text: Most massive stars experience binary interactions in their lifetimes that
can alter both the surface and core structure of the stripped star with significant
effects on their ultimate fate as core-collapse supernovae. However, core-collapse
supernovae simulations to date have focused almost exclusively on the evolution
of single stars. We present a systematic simulation study of single and binary-stripped
stars with the same initial mass as candidates for core-collapse supernovae (11–21
M⊙). Generally, we find that binary-stripped stars core tend to have a smaller
compactness parameter, with a more prominent, deeper silicon/oxygen interface,
and explode preferentially to the corresponding single stars of the same initial
mass. Such a dichotomy of behavior between these two modes of evolution would
have important implications for supernovae statistics, including the final neutron
star masses, explosion energies, and nucleosynthetic yields. Binary-stripped remnants
are also well poised to populate the possible mass gap between the heaviest neutron
stars and the lightest black holes. Our work presents an improvement along two
fronts, as we self-consistently account for the pre-collapse stellar evolution
and the subsequent explosion outcome. Even so, our results emphasize the need
for more detailed stellar evolutionary models to capture the sensitive nature
of explosion outcome.

text: The B emission-line stars are rapid rotators that were probably spun up by
mass and angular momentum accretion through mass transfer in an interacting binary.
Mass transfer will strip the donor star of its envelope to create a small and
hot subdwarf remnant. Here we report on Hubble Space Telescope/STIS far-ultraviolet
spectroscopy of a sample of Be stars that reveals the presence of the hot sdO
companion through the calculation of cross-correlation functions of the observed
and model spectra. We clearly detect the spectral signature of the sdO star in
10 of the 13 stars in the sample, and the spectral signals indicate that the sdO
stars are hot, relatively faint, and slowly rotating as predicted by models. A
comparison of their temperatures and radii with evolutionary tracks indicates
that the sdO stars occupy the relatively long-lived, He-core burning stage. Only
1 of the 10 detections was a known binary prior to this investigation, which emphasizes
the difficulty of finding such Be+sdO binaries through optical spectroscopy. However,
these results and others indicate that many Be stars probably host hot subdwarf
companions.

text: "Context. Observations of massive stars in open clusters younger than ∼8 Myr
have shown that a majority of them are in binary systems, most of which will interact
during their life. While these can be used as a proxy of the initial multiplicity
properties, studying populations of massive stars older than ∼20 Myr allows us
to probe the outcome of these interactions after a significant number of systems
have experienced mass and angular momentum transfer and may even have merged.\r\n\r\nAims.
Using multi-epoch integral-field spectroscopy, we aim to investigate the multiplicity
properties of the massive-star population in the dense core of the ∼40 Myr old
cluster NGC 330 in the Small Magellanic Cloud in order to search for possible
imprints of stellar evolution on the multiplicity properties.\r\n\r\nMethods.
We obtained six epochs of VLT/MUSE observations operated in wide-field mode with
the extended wavelength setup and supported by adaptive optics. We extracted spectra
and measured radial velocities for stars brighter than mF814W = 19. We identified
single-lined spectroscopic binaries through significant RV variability with a
peak-to-peak amplitude larger than 20 km s−1. We also identified double-lined
spectroscopic binaries, and quantified the observational biases for binary detection.
In particular, we took into account that binary systems with similar line strengths
are difficult to detect in our data set.\r\n\r\nResults. The observed spectroscopic
binary fraction among stars brighter than mF814W = 19 (approximately 5.5 M⊙ on
the main sequence) is fSBobs = 13.2 ± 2.0%. Considering period and mass ratio
ranges from log(P) = 0.15−3.5 (about 1.4 to 3160 d), q = 0.1−1.0, and a representative
set of orbital parameter distributions, we find a bias-corrected close binary
fraction of fcl = 34−7+8%. This fraction seems to decline for the fainter stars,
which indicates either that the close binary fraction drops in the B-type domain,
or that the period distribution becomes more heavily weighted toward longer orbital
periods. We further find that both fractions vary strongly in different regions
of the color-magnitude diagram, which corresponds to different evolutionary stages.
This probably reveals the imprint of the binary history of different groups of
stars. In particular, we find that the observed spectroscopic binary fraction
of Be stars (fSBobs = 2 ± 2%) is significantly lower than that of B-type stars
(fSBobs = 9 ± 2%).\r\n\r\nConclusions. We provide the first homogeneous radial
velocity study of a large sample of B-type stars at a low metallicity ([Fe/H]
≲ −1.0). The overall bias-corrected close binary fraction (log(P) < 3.5 d) of
the B-star population in NGC 330 is lower than the fraction reported for younger
Galactic and Large Magellanic Cloud clusters in previous works. More data are
needed, however, to establish whether the observed differences are caused by an
age or a metallicity effect."

text: The majority of massive stars live in binary or multiple systems and will
interact with a companion during their lifetimes, which helps to explain the observed
diversity of core-collapse supernovae. Donor stars in binary systems can lose
most of their hydrogen-rich envelopes through mass transfer. As a result, not
only are the surface properties affected, but so is the core structure. However,
most calculations of the core-collapse properties of massive stars rely on single-star
models. We present a systematic study of the difference between the pre-supernova
structures of single stars and stars of the same initial mass (11–21 M⊙) that
have been stripped due to stable post-main-sequence mass transfer at solar metallicity.
We present the pre-supernova core composition with novel diagrams that give an
intuitive representation of the isotope distribution. As shown in previous studies,
at the edge of the carbon-oxygen core, the binary-stripped star models contain
an extended gradient of carbon, oxygen, and neon. This layer remains until core
collapse and is more extended in mass for higher initial stellar masses. It originates
from the receding of the convective helium core during core helium burning in
binary-stripped stars, which does not occur in single-star models. We find that
this same evolutionary phase leads to systematic differences in the final density
and nuclear energy generation profiles. Binary-stripped star models have systematically
higher total masses of carbon at the moment of core collapse compared to single-star
models, which likely results in systematically different supernova yields. In
about half of our models, the silicon-burning and oxygen-rich layers merge after
core silicon burning. We discuss the implications of our findings for the “explodability”,
supernova observations, and nucleosynthesis of these stars. Our models are publicly
available and can be readily used as input for detailed supernova simulations.

text: Helium star–carbon-oxygen white dwarf (CO WD) binaries are potential single-degenerate
progenitor systems of thermonuclear supernovae. Revisiting a set of binary evolution
calculations using the stellar evolution code MESA, we refine our previous predictions
about which systems can lead to a thermonuclear supernova and then characterize
the properties of the helium star donor at the time of explosion. We convert these
model properties to near-UV/optical magnitudes assuming a blackbody spectrum and
support this approach using a matched stellar atmosphere model. These models will
be valuable to compare with pre-explosion imaging for future supernovae, though
we emphasize the observational difficulty of detecting extremely blue companions.
The pre-explosion source detected in association with SN 2012Z has been interpreted
as a helium star binary containing an initially ultra-massive WD in a multiday
orbit. However, extending our binary models to initial CO WD masses of up to 1.2
M⊙, we find that these systems undergo off-center carbon ignitions and thus are
not expected to produce thermonuclear supernovae. This tension suggests that,
if SN 2012Z is associated with a helium star–WD binary, then the pre-explosion
optical light from the system must be significantly modified by the binary environment
and/or the WD does not have a carbon-rich interior composition.

text: Most massive stars are born in binaries close enough for mass transfer episodes.
These modify the appearance, structure, and future evolution of both stars. We
compute the evolution of a 100-day-period binary, consisting initially of a 25
M⊙ star and a 17 M⊙ star, which experiences stable mass transfer. We focus on
the impact of mass accretion on the surface composition, internal rotation, and
structure of the accretor. To anchor our models, we show that our accretor broadly
reproduces the properties of ζ Ophiuchi, which has long been proposed to have
accreted mass before being ejected as a runaway star when the companion exploded.
We compare our accretor to models of single rotating stars and find that the later
and stronger spin-up provided by mass accretion produces significant differences.
Specifically, the core of the accretor retains higher spin at the end of the main
sequence, and a convective layer develops that changes its density profile. Moreover,
the surface of the accretor star is polluted by CNO-processed material donated
by the companion. Our models show effects of mass accretion in binaries that are
not captured in single rotating stellar models. This possibly impacts the further
evolution (either in a binary or as single stars), the final collapse, and the
resulting spin of the compact object.

prototypical three-dimensional topological insulator bismuth selenide through
the process of high-order harmonic generation. We find that the generation efficiency
increases as the laser polarization is changed from linear to elliptical, and
it becomes maximum for circular polarization. With the aid of a microscopic theory
and a detailed analysis of the measured spectra, we reveal that such anomalous
enhancement encodes the characteristic topology of the band structure that originates
from the interplay of strong spin–orbit coupling and time-reversal symmetry protection.
The implications are in ultrafast probing of topological phase transitions, light-field
driven dissipationless electronics, and quantum computation.

text: We investigate theoretically the strong-field regime of light-matter interactions
in the topological-insulator class of quantum materials. In particular, we focus
on the process of nonperturbative high-order harmonic generation from the paradigmatic
three-dimensional topological insulator bismuth selenide (Bi2Se3) subjected to
intense midinfrared laser fields. We analyze the contributions from the spin-orbit-coupled
bulk states and the topological surface bands separately and reveal a major difference
in how their harmonic yields depend on the ellipticity of the laser field. Bulk
harmonics show a monotonic decrease in their yield as the ellipticity increases,
in a manner reminiscent of high harmonic generation in gaseous media. However,
the surface contribution exhibits a highly nontrivial dependence, culminating
with a maximum for circularly polarized fields. We attribute the observed anomalous
behavior to (i) the enhanced amplitude and the circular pattern of the interband
dipole and the Berry connections in the vicinity of the Dirac point and (ii) the
influence of the higher-order, hexagonal warping terms in the Hamiltonian, which
are responsible for the hexagonal deformation of the energy surface at higher
momenta. The latter are associated directly with spin-orbit-coupling parameters.
Our results thus establish the sensitivity of strong-field-driven high harmonic
emission to the topology of the band structure as well as to the manifestations
of spin-orbit interaction.

text: Shape resonances play a central role in many areas of science, but the real-time
measurement of the associated many-body dynamics remains challenging. Here, we
present measurements of recoil frame angle-resolved photoionization delays in
the vicinity of shape resonances of CF4. This technique provides insights into
the spatiotemporal photoionization dynamics of molecular shape resonances. We
find delays of up to ∼600 as in the ionization out of the highest occupied molecular
orbital (HOMO) with a strong dependence on the emission direction and a pronounced
asymmetry along the dissociation axis. Comparison with quantum-scattering calculations
traces the asymmetries to the interference of a small subset of partial waves
at low kinetic energies and, additionally, to the interference of two overlapping
shape resonances in the HOMO-1 channel. Our experimental and theoretical results
establish a broadly applicable approach to space- and time-resolved photoionization
dynamics in the molecular frame.

text: UVEX is a proposed medium class Explorer mission designed to provide crucial
missing capabilities that will address objectives central to a broad range of
modern astrophysics. The UVEX design has two co-aligned wide-field imagers operating
in the FUV and NUV and a powerful broadband medium resolution spectrometer. In
its two-year baseline mission, UVEX will perform a multi-cadence synoptic all-sky
survey 50/100 times deeper than GALEX in the NUV/FUV, cadenced surveys of the
Large and Small Magellanic Clouds, rapid target of opportunity followup, as well
as spectroscopic followup of samples of stars and galaxies. The science program
is built around three pillars. First, UVEX will explore the low-mass, low-metallicity
galaxy frontier through imaging and spectroscopic surveys that will probe key
aspects of the evolution of galaxies by understanding how star formation and stellar
evolution at low metallicities affect the growth and evolution of low-metallicity,
low-mass galaxies in the local universe. Such galaxies contain half the mass in
the local universe, and are analogs for the first galaxies, but observed at distances
that make them accessible to detailed study. Second, UVEX will explore the dynamic
universe through time-domain surveys and prompt spectroscopic followup capability
will probe the environments, energetics, and emission processes in the early aftermaths
of gravitational wave-discovered compact object mergers, discover hot, fast UV
transients, and diagnose the early stages of stellar explosions. Finally, UVEX
will become a key community resource by leaving a large all-sky legacy data set,
enabling a wide range of scientific studies and filling a gap in the new generation
of wide-field, sensitive optical and infrared surveys provided by the Rubin, Euclid,
and Roman observatories. This paper discusses the scientific potential of UVEX,
and the broad scientific program.

text: We study systems of nonlinear partial differential equations of parabolic
type, in which the elliptic operator is replaced by the first-order divergence
operator acting on a flux function, which is related to the spatial gradient of
the unknown through an additional implicit equation. This setting, broad enough
in terms of applications, significantly expands the paradigm of nonlinear parabolic
problems. Formulating four conditions concerning the form of the implicit equation,
we first show that these conditions describe a maximal monotone p-coercive graph.
We then establish the global-in-time and large-data existence of a (weak) solution
and its uniqueness. To this end, we adopt and significantly generalize Minty’s
method of monotone mappings. A unified theory, containing several novel tools,
is developed in a way to be tractable from the point of view of numerical approximations.

text: The popularity of permissioned blockchain systems demands BFT SMR protocols
that are efficient under good network conditions (synchrony) and robust under
bad network conditions (asynchrony). The state-of-the-art partially synchronous
BFT SMR protocols provide optimal linear communication cost per decision under
synchrony and good leaders, but lose liveness under asynchrony. On the other hand,
the state-of-the-art asynchronous BFT SMR protocols are live even under asynchrony,
but always pay quadratic cost even under synchrony. In this paper, we propose
a BFT SMR protocol that achieves the best of both worlds -- optimal linear cost
per decision under good networks and leaders, optimal quadratic cost per decision
under bad networks, and remains always live.

text: The analogy between an equilibrium partition function and the return probability
in many-body unitary dynamics has led to the concept of dynamical quantum phase
transition (DQPT). DQPTs are defined by nonanalyticities in the return amplitude
and are present in many models. In some cases, DQPTs can be related to equilibrium
concepts, such as order parameters, yet their universal description is an open
question. In this Letter, we provide first steps toward a classification of DQPTs
by using a matrix product state description of unitary dynamics in the thermodynamic
limit. This allows us to distinguish the two limiting cases of “precession” and
“entanglement” DQPTs, which are illustrated using an analytical description in
the quantum Ising model. While precession DQPTs are characterized by a large entanglement
gap and are semiclassical in their nature, entanglement DQPTs occur near avoided
crossings in the entanglement spectrum and can be distinguished by a complex pattern
of nonlocal correlations. We demonstrate the existence of precession and entanglement
DQPTs beyond Ising models, discuss observables that can distinguish them, and
relate their interplay to complex DQPT phenomenology.

text: The quality control system for messenger RNA (mRNA) is fundamental for cellular
activities in eukaryotes. To elucidate the molecular mechanism of 3'-Phosphoinositide-Dependent
Protein Kinase1 (PDK1), a master regulator that is essential throughout eukaryotic
growth and development, we employed a forward genetic approach to screen for suppressors
of the loss-of-function T-DNA insertion double mutant pdk1.1 pdk1.2 in Arabidopsis
thaliana. Notably, the severe growth attenuation of pdk1.1 pdk1.2 was rescued
by sop21 (suppressor of pdk1.1 pdk1.2), which harbours a loss-of-function mutation
in PELOTA1 (PEL1). PEL1 is a homologue of mammalian PELOTA and yeast (Saccharomyces
cerevisiae) DOM34p, which each form a heterodimeric complex with the GTPase HBS1
(HSP70 SUBFAMILY B SUPPRESSOR1, also called SUPERKILLER PROTEIN7, SKI7), a protein
that is responsible for ribosomal rescue and thereby assures the quality and fidelity
of mRNA molecules during translation. Genetic analysis further revealed that a
dysfunctional PEL1-HBS1 complex failed to degrade the T-DNA-disrupted PDK1 transcripts,
which were truncated but functional, and thus rescued the growth and developmental
defects of pdk1.1 pdk1.2. Our studies demonstrated the functionality of a homologous
PELOTA-HBS1 complex and identified its essential regulatory role in plants, providing
insights into the mechanism of mRNA quality control.

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: Polar subcellular localization of the PIN exporters of the phytohormone auxin
is a key determinant of directional, intercellular auxin transport and thus a
central topic of both plant cell and developmental biology. Arabidopsis mutants
lacking PID, a kinase that phosphorylates PINs, or the MAB4/MEL proteins of unknown
molecular function display PIN polarity defects and phenocopy pin mutants, but
mechanistic insights into how these factors convey PIN polarity are missing. Here,
by combining protein biochemistry with quantitative live-cell imaging, we demonstrate
that PINs, MAB4/MELs, and AGC kinases interact in the same complex at the plasma
membrane. MAB4/MELs are recruited to the plasma membrane by the PINs and in concert
with the AGC kinases maintain PIN polarity through limiting lateral diffusion-based
escape of PINs from the polar domain. The PIN-MAB4/MEL-PID protein complex has
self-reinforcing properties thanks to positive feedback between AGC kinase-mediated
PIN phosphorylation and MAB4/MEL recruitment. We thus uncover the molecular mechanism
by which AGC kinases and MAB4/MEL proteins regulate PIN localization and plant
development.

text: Plants are able to orient their growth according to gravity, which ultimately
controls both shoot and root architecture.1 Gravitropism is a dynamic process
whereby gravistimulation induces the asymmetric distribution of the plant hormone
auxin, leading to asymmetric growth, organ bending, and subsequent reset of auxin
distribution back to the original pre-gravistimulation situation.1, 2, 3 Differential
auxin accumulation during the gravitropic response depends on the activity of
polarly localized PIN-FORMED (PIN) auxin-efflux carriers.1, 2, 3, 4 In particular,
the timing of this dynamic response is regulated by PIN2,5,6 but the underlying
molecular mechanisms are poorly understood. Here, we show that MEMBRANE ASSOCIATED
KINASE REGULATOR2 (MAKR2) controls the pace of the root gravitropic response.
We found that MAKR2 is required for the PIN2 asymmetry during gravitropism by
acting as a negative regulator of the cell-surface signaling mediated by the receptor-like
kinase TRANSMEMBRANE KINASE1 (TMK1).2,7, 8, 9, 10 Furthermore, we show that
the MAKR2 inhibitory effect on TMK1 signaling is antagonized by auxin itself,
which triggers rapid MAKR2 membrane dissociation in a TMK1-dependent manner. Our
findings suggest that the timing of the root gravitropic response is orchestrated
by the reversible inhibition of the TMK1 signaling pathway at the cell surface.

text: Electrodepositing insulating lithium peroxide (Li2O2) is the key process during
discharge of aprotic Li–O2 batteries and determines rate, capacity, and reversibility.
Current understanding states that the partition between surface adsorbed and dissolved
lithium superoxide governs whether Li2O2 grows as a conformal surface film or
larger particles, leading to low or high capacities, respectively. However, better
understanding governing factors for Li2O2 packing density and capacity requires
structural sensitive in situ metrologies. Here, we establish in situ small- and
wide-angle X-ray scattering (SAXS/WAXS) as a suitable method to record the Li2O2
phase evolution with atomic to submicrometer resolution during cycling a custom-built
in situ Li–O2 cell. Combined with sophisticated data analysis, SAXS allows retrieving
rich quantitative structural information from complex multiphase systems. Surprisingly,
we find that features are absent that would point at a Li2O2 surface film formed
via two consecutive electron transfers, even in poorly solvating electrolytes
thought to be prototypical for surface growth. All scattering data can be modeled
by stacks of thin Li2O2 platelets potentially forming large toroidal particles.
Li2O2 solution growth is further justified by rotating ring-disk electrode measurements
and electron microscopy. Higher discharge overpotentials lead to smaller Li2O2
particles, but there is no transition to an electronically passivating, conformal
Li2O2 coating. Hence, mass transport of reactive species rather than electronic
transport through a Li2O2 film limits the discharge capacity. Provided that species
mobilities and carbon surface areas are high, this allows for high discharge capacities
even in weakly solvating electrolytes. The currently accepted Li–O2 reaction mechanism
ought to be reconsidered.

text: 'Lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) based water-in-salt electrolytes
(WiSEs) has recently emerged as a new promising class of electrolytes, primarily
owing to their wide electrochemical stability windows (~3–4 V), that by far exceed
the thermodynamic stability window of water (1.23 V). Upon increasing the salt
concentration towards superconcentration the onset of the oxygen evolution reaction
(OER) shifts more significantly than the hydrogen evolution reaction (HER) does.
The OER shift has been explained by the accumulation of hydrophobic anions blocking
water access to the electrode surface, hence by double layer theory. Here we demonstrate
that the processes during oxidation are much more complex, involving OER, carbon
and salt decomposition by OER intermediates, and salt precipitation upon local
oversaturation. The positive shift in the onset potential of oxidation currents
was elucidated by combining several advanced analysis techniques: rotating ring-disk
electrode voltammetry, online electrochemical mass spectrometry, and X-ray photoelectron
spectroscopy, using both dilute and superconcentrated electrolytes. The results
demonstrate the importance of reactive OER intermediates and surface films for
electrolyte and electrode stability and motivate further studies of the nature
of the electrode.'

text: Dendritic cells (DCs) are crucial for the priming of naive T cells and the
initiation of adaptive immunity. Priming is initiated at a heterologous cell–cell
contact, the immunological synapse (IS). While it is established that F-actin
dynamics regulates signaling at the T cell side of the contact, little is known
about the cytoskeletal contribution on the DC side. Here, we show that the DC
actin cytoskeleton is decisive for the formation of a multifocal synaptic structure,
which correlates with T cell priming efficiency. DC actin at the IS appears in
transient foci that are dynamized by the WAVE regulatory complex (WRC). The absence
of the WRC in DCs leads to stabilized contacts with T cells, caused by an increase
in ICAM1-integrin–mediated cell–cell adhesion. This results in lower numbers of
activated and proliferating T cells, demonstrating an important role for DC actin
in the regulation of immune synapse functionality.

text: The sensory and cognitive abilities of the mammalian neocortex are underpinned
by intricate columnar and laminar circuits formed from an array of diverse neuronal
populations. One approach to determining how interactions between these circuit
components give rise to complex behavior is to investigate the rules by which
cortical circuits are formed and acquire functionality during development. This
review summarizes recent research on the development of the neocortex, from genetic
determination in neural stem cells through to the dynamic role that specific neuronal
populations play in the earliest circuits of neocortex, and how they contribute
to emergent function and cognition. While many of these endeavors take advantage
of model systems, consideration will also be given to advances in our understanding
of activity in nascent human circuits. Such cross-species perspective is imperative
when investigating the mechanisms underlying the dysfunction of early neocortical
circuits in neurodevelopmental disorders, so that one can identify targets amenable
to therapeutic intervention.

text: "We study the problem of recovering an unknown signal \U0001D465\U0001D465
given measurements obtained from a generalized linear model with a Gaussian sensing
matrix. Two popular solutions are based on a linear estimator \U0001D465\U0001D465^L
and a spectral estimator \U0001D465\U0001D465^s. The former is a data-dependent
linear combination of the columns of the measurement matrix, and its analysis
is quite simple. The latter is the principal eigenvector of a data-dependent matrix,
and a recent line of work has studied its performance. In this paper, we show
how to optimally combine \U0001D465\U0001D465^L and \U0001D465\U0001D465^s. At
the heart of our analysis is the exact characterization of the empirical joint
distribution of (\U0001D465\U0001D465,\U0001D465\U0001D465^L,\U0001D465\U0001D465^s)
in the high-dimensional limit. This allows us to compute the Bayes-optimal combination
of \U0001D465\U0001D465^L and \U0001D465\U0001D465^s, given the limiting distribution
of the signal \U0001D465\U0001D465. When the distribution of the signal is Gaussian,
then the Bayes-optimal combination has the form \U0001D703\U0001D465\U0001D465^L+\U0001D465\U0001D465^s
and we derive the optimal combination coefficient. In order to establish the limiting
distribution of (\U0001D465\U0001D465,\U0001D465\U0001D465^L,\U0001D465\U0001D465^s),
we design and analyze an approximate message passing algorithm whose iterates
give \U0001D465\U0001D465^L and approach \U0001D465\U0001D465^s. Numerical simulations
demonstrate the improvement of the proposed combination with respect to the two
methods considered separately."

a universal constant independent of the interaction potential V. The results hold

text: In this paper, we present two new inertial projection-type methods for solving
multivalued variational inequality problems in finite-dimensional spaces. We establish
the convergence of the sequence generated by these methods when the multivalued
mapping associated with the problem is only required to be locally bounded without
any monotonicity assumption. Furthermore, the inertial techniques that we employ
in this paper are quite different from the ones used in most papers. Moreover,
based on the weaker assumptions on the inertial factor in our methods, we derive
several special cases of our methods. Finally, we present some experimental results
to illustrate the profits that we gain by introducing the inertial extrapolation
steps.

text: 'We study the probabilistic convergence between the mapper graph and the Reeb
graph of a topological space X equipped with a continuous function f:X→R. We first
give a categorification of the mapper graph and the Reeb graph by interpreting
them in terms of cosheaves and stratified covers of the real line R. We then introduce
a variant of the classic mapper graph of Singh et al. (in: Eurographics symposium
on point-based graphics, 2007), referred to as the enhanced mapper graph, and
demonstrate that such a construction approximates the Reeb graph of (X,f) when
it is applied to points randomly sampled from a probability density function concentrated
on (X,f). Our techniques are based on the interleaving distance of constructible
cosheaves and topological estimation via kernel density estimates. Following Munch
and Wang (In: 32nd international symposium on computational geometry, volume 51
of Leibniz international proceedings in informatics (LIPIcs), Dagstuhl, Germany,
pp 53:1–53:16, 2016), we first show that the mapper graph of (X,f), a constructible
R-space (with a fixed open cover), approximates the Reeb graph of the same space.
We then construct an isomorphism between the mapper of (X,f) to the mapper of
a super-level set of a probability density function concentrated on (X,f). Finally,
building on the approach of Bobrowski et al. (Bernoulli 23(1):288–328, 2017b),
we show that, with high probability, we can recover the mapper of the super-level
set given a sufficiently large sample. Our work is the first to consider the mapper
construction using the theory of cosheaves in a probabilistic setting. It is part
of an ongoing effort to combine sheaf theory, probability, and statistics, to
support topological data analysis with random data.'

text: 'This paper analyses the conditions for local adaptation in a metapopulation
with infinitely many islands under a model of hard selection, where population
size depends on local fitness. Each island belongs to one of two distinct ecological
niches or habitats. Fitness is influenced by an additive trait which is under
habitat‐dependent directional selection. Our analysis is based on the diffusion
approximation and accounts for both genetic drift and demographic stochasticity.
By neglecting linkage disequilibria, it yields the joint distribution of allele
frequencies and population size on each island. We find that under hard selection,
the conditions for local adaptation in a rare habitat are more restrictive for
more polygenic traits: even moderate migration load per locus at very many loci
is sufficient for population sizes to decline. This further reduces the efficacy
of selection at individual loci due to increased drift and because smaller populations
are more prone to swamping due to migration, causing a positive feedback between
increasing maladaptation and declining population sizes. Our analysis also highlights
the importance of demographic stochasticity, which exacerbates the decline in
numbers of maladapted populations, leading to population collapse in the rare
habitat at significantly lower migration than predicted by deterministic arguments.'

text: If there are no constraints on the process of speciation, then the number
of species might be expected to match the number of available niches and this
number might be indefinitely large. One possible constraint is the opportunity
for allopatric divergence. In 1981, Felsenstein used a simple and elegant model
to ask if there might also be genetic constraints. He showed that progress towards
speciation could be described by the build‐up of linkage disequilibrium among
divergently selected loci and between these loci and those contributing to other
forms of reproductive isolation. Therefore, speciation is opposed by recombination,
because it tends to break down linkage disequilibria. Felsenstein then introduced
a crucial distinction between “two‐allele” models, which are subject to this effect,
and “one‐allele” models, which are free from the recombination constraint. These
fundamentally important insights have been the foundation for both empirical and
theoretical studies of speciation ever since.

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: "• The phenylpropanoid pathway serves a central role in plant metabolism,
providing numerous compounds involved in diverse physiological processes. Most
carbon entering the pathway is incorporated into lignin. Although several phenylpropanoid
pathway mutants show seedling growth arrest, the role for lignin in seedling growth
and development is unexplored.\r\n• We use complementary pharmacological and genetic
approaches to block CINNAMATE‐4‐HYDROXYLASE (C4H) functionality in Arabidopsis
seedlings and a set of molecular and biochemical techniques to investigate the
underlying phenotypes.\r\n• Blocking C4H resulted in reduced lateral rooting and
increased adventitious rooting apically in the hypocotyl. These phenotypes coincided
with an inhibition in auxin transport. The upstream accumulation in cis‐cinnamic
acid was found to likely cause polar auxin transport inhibition. Conversely, a
downstream depletion in lignin perturbed phloem‐mediated auxin transport. Restoring
lignin deposition effectively reestablished phloem transport and, accordingly,
auxin homeostasis.\r\n• Our results show that the accumulation of bioactive intermediates
and depletion in lignin jointly cause the aberrant phenotypes upon blocking C4H,
and demonstrate that proper deposition of lignin is essential for the establishment
of auxin distribution in seedlings. Our data position the phenylpropanoid pathway
and lignin in a new physiological framework, consolidating their importance in
plant growth and development."

text: To adapt to the diverse array of biotic and abiotic cues, plants have evolved
sophisticated mechanisms to sense changes in environmental conditions and modulate
their growth. Growth-promoting hormones and defence signalling fine tune plant
development antagonistically. During host-pathogen interactions, this defence-growth
trade-off is mediated by the counteractive effects of the defence hormone salicylic
acid (SA) and the growth hormone auxin. Here we revealed an underlying mechanism
of SA regulating auxin signalling by constraining the plasma membrane dynamics
of PIN2 auxin efflux transporter in Arabidopsis thaliana roots. The lateral diffusion
of PIN2 proteins is constrained by SA signalling, during which PIN2 proteins are
condensed into hyperclusters depending on REM1.2-mediated nanodomain compartmentalisation.
Furthermore, membrane nanodomain compartmentalisation by SA or Remorin (REM) assembly
significantly suppressed clathrin-mediated endocytosis. Consequently, SA-induced
heterogeneous surface condensation disrupted asymmetric auxin distribution and
the resultant gravitropic response. Our results demonstrated a defence-growth
trade-off mechanism by which SA signalling crosstalked with auxin transport by
concentrating membrane-resident PIN2 into heterogeneous compartments.

text: Hartree–Fock theory has been justified as a mean-field approximation for fermionic
systems. However, it suffers from some defects in predicting physical properties,
making necessary a theory of quantum correlations. Recently, bosonization of many-body
correlations has been rigorously justified as an upper bound on the correlation
energy at high density with weak interactions. We review the bosonic approximation,
deriving an effective Hamiltonian. We then show that for systems with Coulomb
interaction this effective theory predicts collective excitations (plasmons) in
accordance with the random phase approximation of Bohm and Pines, and with experimental
observation.

text: "In this thesis we study persistence of multi-covers of Euclidean balls and
the geometric structures underlying their computation, in particular Delaunay
mosaics and Voronoi tessellations. The k-fold cover for some discrete input point
set consists of the space where at least k balls of radius r around the input
points overlap. Persistence is a notion that captures, in some sense, the topology
of the shape underlying the input. While persistence is usually computed for the
union of balls, the k-fold cover is of interest as it captures local density,\r\nand
thus might approximate the shape of the input better if the input data is noisy.
To compute persistence of these k-fold covers, we need a discretization that is
provided by higher-order Delaunay mosaics. We present and implement a simple and
efficient algorithm for the computation of higher-order Delaunay mosaics, and
use it to give experimental results for their combinatorial properties. The algorithm
makes use of a new geometric structure, the rhomboid tiling. It contains the higher-order
Delaunay mosaics as slices, and by introducing a filtration\r\nfunction on the
tiling, we also obtain higher-order α-shapes as slices. These allow us to compute
persistence of the multi-covers for varying radius r; the computation for varying
k is less straight-foward and involves the rhomboid tiling directly. We apply
our algorithms to experimental sphere packings to shed light on their structural
properties. Finally, inspired by periodic structures in packings and materials,
we propose and implement an algorithm for periodic Delaunay triangulations to
be integrated into the Computational Geometry Algorithms Library (CGAL), and discuss
the implications on persistence for periodic data sets."

text: "In the first part of the thesis we consider Hermitian random matrices. Firstly,
we consider sample covariance matrices XX∗ with X having independent identically
distributed (i.i.d.) centred entries. We prove a Central Limit Theorem for differences
of linear statistics of XX∗ and its minor after removing the first column of X.
Secondly, we consider Wigner-type matrices and prove that the eigenvalue statistics
near cusp singularities of the limiting density of states are universal and that
they form a Pearcey process. Since the limiting eigenvalue distribution admits
only square root (edge) and cubic root (cusp) singularities, this concludes the
third and last remaining case of the Wigner-Dyson-Mehta universality conjecture.
The main technical ingredients are an optimal local law at the cusp, and the proof
of the fast relaxation to equilibrium of the Dyson Brownian motion in the cusp
regime.\r\nIn the second part we consider non-Hermitian matrices X with centred
i.i.d. entries. We normalise the entries of X to have variance N −1. It is well
known that the empirical eigenvalue density converges to the uniform distribution
on the unit disk (circular law). In the first project, we prove universality of
the local eigenvalue statistics close to the edge of the spectrum. This is the
non-Hermitian analogue of the TracyWidom universality at the Hermitian edge. Technically
we analyse the evolution of the spectral distribution of X along the Ornstein-Uhlenbeck
flow for very long time\r\n(up to t = +∞). In the second project, we consider
linear statistics of eigenvalues for macroscopic test functions f in the Sobolev
space H2+ϵ and prove their convergence to the projection of the Gaussian Free
Field on the unit disk. We prove this result for non-Hermitian matrices with real
or complex entries. The main technical ingredients are: (i) local law for products
of two resolvents at different spectral parameters, (ii) analysis of correlated
Dyson Brownian motions.\r\nIn the third and final part we discuss the mathematically
rigorous application of supersymmetric techniques (SUSY ) to give a lower tail
estimate of the lowest singular value of X − z, with z ∈ C. More precisely, we
use superbosonisation formula to give an integral representation of the resolvent
of (X − z)(X − z)∗ which reduces to two and three contour integrals in the complex
and real case, respectively. The rigorous analysis of these integrals is quite
challenging since simple saddle point analysis cannot be applied (the main contribution
comes from a non-trivial manifold). Our result\r\nimproves classical smoothing
inequalities in the regime |z| ≈ 1; this result is essential to prove edge universality
for i.i.d. non-Hermitian matrices."

text: 'We study the inductive bias of two-layer ReLU networks trained by gradient
flow. We identify a class of easy-to-learn (`orthogonally separable'') datasets,
and characterise the solution that ReLU networks trained on such datasets converge
to. Irrespective of network width, the solution turns out to be a combination
of two max-margin classifiers: one corresponding to the positive data subset and
one corresponding to the negative data subset. The proof is based on the recently
introduced concept of extremal sectors, for which we prove a number of properties
in the context of orthogonal separability. In particular, we prove stationarity
of activation patterns from some time onwards, which enables a reduction of the
ReLU network to an ensemble of linear subnetworks.'

text: We investigate the Fröhlich polaron model on a three-dimensional torus, and
give a proof of the second-order quantum corrections to its ground-state energy
in the strong-coupling limit. Compared to previous work in the confined case,
the translational symmetry (and its breaking in the Pekar approximation) makes
the analysis substantially more challenging.

text: 'Stateless model checking (SMC) is one of the standard approaches to the verification
of concurrent programs. As scheduling non-determinism creates exponentially large
spaces of thread interleavings, SMC attempts to partition this space into equivalence
classes and explore only a few representatives from each class. The efficiency
of this approach depends on two factors: (a) the coarseness of the partitioning,
and (b) the time to generate representatives in each class. For this reason, the
search for coarse partitionings that are efficiently explorable is an active research
challenge. In this work we present RVF-SMC , a new SMC algorithm that uses a
novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are
deemed equivalent if they agree on the value obtained in each read event, and
read events induce consistent causal orderings between them. The RVF partitioning
is provably coarser than recent approaches based on Mazurkiewicz and “reads-from”
partitionings. Our experimental evaluation reveals that RVF is quite often a very
effective equivalence, as the underlying partitioning is exponentially coarser
than other approaches. Moreover, RVF-SMC generates representatives very efficiently,
as the reduction in the partitioning is often met with significant speed-ups in
the model checking task.'

text: The present thesis is concerned with the derivation of weak-strong uniqueness
principles for curvature driven interface evolution problems not satisfying a
comparison principle. The specific examples being treated are two-phase Navier-Stokes
flow with surface tension, modeling the evolution of two incompressible, viscous
and immiscible fluids separated by a sharp interface, and multiphase mean curvature
flow, which serves as an idealized model for the motion of grain boundaries in
an annealing polycrystalline material. Our main results - obtained in joint works
with Julian Fischer, Tim Laux and Theresa M. Simon - state that prior to the formation
of geometric singularities due to topology changes, the weak solution concept
of Abels (Interfaces Free Bound. 9, 2007) to two-phase Navier-Stokes flow with
surface tension and the weak solution concept of Laux and Otto (Calc. Var. Partial
Differential Equations 55, 2016) to multiphase mean curvature flow (for networks
in R^2 or double bubbles in R^3) represents the unique solution to these interface
evolution problems within the class of classical solutions, respectively. To the
best of the author's knowledge, for interface evolution problems not admitting
a geometric comparison principle the derivation of a weak-strong uniqueness principle
represented an open problem, so that the works contained in the present thesis
constitute the first positive results in this direction. The key ingredient of
our approach consists of the introduction of a novel concept of relative entropies
for a class of curvature driven interface evolution problems, for which the associated
energy contains an interfacial contribution being proportional to the surface
area of the evolving (network of) interface(s). The interfacial part of the relative
entropy gives sufficient control on the interface error between a weak and a classical
solution, and its time evolution can be computed, at least in principle, for any
energy dissipating weak solution concept. A resulting stability estimate for the
relative entropy essentially entails the above mentioned weak-strong uniqueness
principles. The present thesis contains a detailed introduction to our relative
entropy approach, which in particular highlights potential applications to other
problems in curvature driven interface evolution not treated in this thesis.

text: "In this work we solve the algorithmic problem of consistency verification
for the TSO and PSO memory models given a reads-from map, denoted VTSO-rf and
VPSO-rf, respectively. For an execution of n events over k threads and d variables,
we establish novel bounds that scale as nk+1 for TSO and as nk+1· min(nk2, 2k·
d) for PSO. Moreover, based on our solution to these problems, we develop an SMC
algorithm under TSO and PSO that uses the RF equivalence. The algorithm is exploration-optimal,
in the sense that it is guaranteed to explore each class of the RF partitioning
exactly once, and spends polynomial time per class when k is bounded. Finally,
we implement all our algorithms in the SMC tool Nidhugg, and perform a large number
of experiments over benchmarks from existing literature. Our experimental results
show that our algorithms for VTSO-rf and VPSO-rf provide significant scalability
improvements over standard alternatives. Moreover, when used for SMC, the RF partitioning
is often much coarser than the standard Shasha-Snir partitioning for TSO/PSO,
which yields a significant speedup in the model checking task.\r\n\r\n"

text: We derive a weak-strong uniqueness principle for BV solutions to multiphase
mean curvature flow of triple line clusters in three dimensions. Our proof is
based on the explicit construction of a gradient-flow calibration in the sense
of the recent work of Fischer et al. [arXiv:2003.05478] for any such cluster.
This extends the two-dimensional construction to the three-dimensional case of
surfaces meeting along triple junctions.

text: There are two elementary superconducting qubit types that derive directly
from the quantum harmonic oscillator. In one, the inductor is replaced by a nonlinear
Josephson junction to realize the widely used charge qubits with a compact phase
variable and a discrete charge wave function. In the other, the junction is added
in parallel, which gives rise to an extended phase variable, continuous wave functions,
and a rich energy-level structure due to the loop topology. While the corresponding
rf superconducting quantum interference device Hamiltonian was introduced as a
quadratic quasi-one-dimensional potential approximation to describe the fluxonium
qubit implemented with long Josephson-junction arrays, in this work we implement
it directly using a linear superinductor formed by a single uninterrupted aluminum
wire. We present a large variety of qubits, all stemming from the same circuit
but with drastically different characteristic energy scales. This includes flux
and fluxonium qubits but also the recently introduced quasicharge qubit with strongly
enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion.
The use of a geometric inductor results in high reproducibility of the inductive
energy as guaranteed by top-down lithography—a key ingredient for intrinsically
protected superconducting qubits.

text: "This PhD thesis is primarily focused on the study of discrete transport problems,
introduced for the first time in the seminal works of Maas [Maa11] and Mielke
[Mie11] on finite state Markov chains and reaction-diffusion equations, respectively.
More in detail, my research focuses on the study of transport costs on graphs,
in particular the convergence and the stability of such problems in the discrete-to-continuum
limit. This thesis also includes some results concerning\r\nnon-commutative optimal
transport. The first chapter of this thesis consists of a general introduction
to the optimal transport problems, both in the discrete, the continuous, and the
non-commutative setting. Chapters 2 and 3 present the content of two works, obtained
in collaboration with Peter Gladbach, Eva Kopfer, and Jan Maas, where we have
been able to show the convergence of discrete transport costs on periodic graphs
to suitable continuous ones, which can be described by means of a homogenisation
result. We first focus on the particular case of quadratic costs on the real line
and then extending the result to more general costs in arbitrary dimension. Our
results are the first complete characterisation of limits of transport costs on
periodic graphs in arbitrary dimension which do not rely on any additional symmetry.
In Chapter 4 we turn our attention to one of the intriguing connection between
evolution equations and optimal transport, represented by the theory of gradient
flows. We show that discrete gradient flow structures associated to a finite volume
approximation of a certain class of diffusive equations (Fokker–Planck) is stable
in the limit of vanishing meshes, reproving the convergence of the scheme via
the method of evolutionary Γ-convergence and exploiting a more variational point
of view on the problem. This is based on a collaboration with Dominik Forkert
and Jan Maas. Chapter 5 represents a change of perspective, moving away from the
discrete world and reaching the non-commutative one. As in the discrete case,
we discuss how classical tools coming from the commutative optimal transport can
be translated into the setting of density matrices. In particular, in this final
chapter we present a non-commutative version of the Schrödinger problem (or entropic
regularised optimal transport problem) and discuss existence and characterisation
of minimisers, a duality result, and present a non-commutative version of the
well-known Sinkhorn algorithm to compute the above mentioned optimisers. This
is based on a joint work with Dario Feliciangeli and Augusto Gerolin. Finally,
Appendix A and B contain some additional material and discussions, with particular
attention to Harnack inequalities and the regularity of flows on discrete spaces."
