text: "Background: The genus Burkholderia consists of species that occupy remarkably
diverse ecological niches. Its best known members are important pathogens, B.
mallei and B. pseudomallei, which cause glanders and melioidosis, respectively.
Burkholderia genomes are unusual due to their multichromosomal organization, generally
comprised of 2-3 chromosomes.\r\n\r\nResults: We performed integrated genomic
analysis of 127 Burkholderia strains. The pan-genome is open with the saturation
to be reached between 86,000 and 88,000 genes. The reconstructed rearrangements
indicate a strong avoidance of intra-replichore inversions that is likely caused
by selection against the transfer of large groups of genes between the leading
and the lagging strands. Translocated genes also tend to retain their position
in the leading or the lagging strand, and this selection is stronger for large
syntenies. Integrated reconstruction of chromosome rearrangements in the context
of strains phylogeny reveals parallel rearrangements that may indicate inversion-based
phase variation and integration of new genomic islands. In particular, we detected
parallel inversions in the second chromosomes of B. pseudomallei with breakpoints
formed by genes encoding membrane components of multidrug resistance complex,
that may be linked to a phase variation mechanism. Two genomic islands, spreading
horizontally between chromosomes, were detected in the B. cepacia group.\r\n\r\nConclusions:
This study demonstrates the power of integrated analysis of pan-genomes, chromosome
rearrangements, and selection regimes. Non-random inversion patterns indicate
selective pressure, inversions are particularly frequent in a recent pathogen
B. mallei, and, together with periods of positive selection at other branches,
may indicate adaptation to new niches. One such adaptation could be a possible
phase variation mechanism in B. pseudomallei."

text: Genome rearrangements have played an important role in the evolution of Yersinia
pestis from its progenitor Yersinia pseudotuberculosis. Traditional phylogenetic
trees for Y. pestis based on sequence comparison have short internal branches
and low bootstrap supports as only a small number of nucleotide substitutions
have occurred. On the other hand, even a small number of genome rearrangements
may resolve topological ambiguities in a phylogenetic tree. We reconstructed phylogenetic
trees based on genome rearrangements using several popular approaches such as
Maximum likelihood for Gene Order and the Bayesian model of genome rearrangements
by inversions. We also reconciled phylogenetic trees for each of the three CRISPR
loci to obtain an integrated scenario of the CRISPR cassette evolution. Analysis
of contradictions between the obtained evolutionary trees yielded numerous parallel
inversions and gain/loss events. Our data indicate that an integrated analysis
of sequence-based and inversion-based trees enhances the resolution of phylogenetic
reconstruction. In contrast, reconstructions of strain relationships based on
solely CRISPR loci may not be reliable, as the history is obscured by large deletions,
obliterating the order of spacer gains. Similarly, numerous parallel gene losses
preclude reconstruction of phylogeny based on gene content.

text: 'Background/Aim: Our aim was to investigate the crosstalk between tumor and
immune cells (M2 macrophages) and its effects on cyclo-oxygenase-2 (COX2) regulation
in canine mammary tumors (CMT). Materials and Methods: Sh1b CMT cells and human
BT474 mammary or HT29 colon cancer cells were co-cultured with canine peripheral
blood mononuclear cells (PBMCs) or with macrophage-like differentiated THP1 monocytes
(dTHP1). Intracellular COX2 expression by PBMCs, dTHP1 and cancer cells was evaluated
by flow cytometry. Results: Co-culturing of Sh1b and canine PBMCs induced COX2
overexpression in CMT cells. In turn, COX2 expression by PBMCs, mostly CD68+ macrophages,
was attenuated by co-culture with Sh1b (p=0.0001). In accordance, co-culture with
dTHP1 prompted intracellular production of COX2 in both Sh1b CMT cells and HT29
human colon cancer cells and reduced production of COX2 in BT474 human mammary
cancer cells. The intracellular COX2 expression from dTHP1 decreased when treated
with conditioned medium from cultured Sh1b and HT29 cancer cells. Conclusion:
Bidirectional COX2 regulation between cancer and monocytes/macrophages might shape
a tolerogenic tumor microenvironment in CMT.'

text: Sharding, or partitioning the system’s state so that different subsets of
participants handle it, is a proven approach to building distributed systems whose
total capacity scales horizontally with the number of participants. Many distributed
ledgers have adopted this approach to increase their performance, however, they
focus on the permissionless setting that assumes the existence of a strong adversary.
In this paper, we deploy channels for permissioned blockchains. Our first contribution
is to adapt sharding on asset-management applications for the permissioned setting,
while preserving liveness and safety even on transactions spanning across-channels.
Our second contribution is to leverage channels as a confidentiality boundary,
enabling different organizations and consortia to preserve their privacy within
their channels and still be part of a bigger collaborative ecosystem. To make
our system concrete we map it on top of Hyperledger Fabric.

text: "Designing a secure permissionless distributed ledger (blockchain) that performs
on par with centralized payment\r\nprocessors, such as Visa, is a challenging
task. Most existing distributed ledgers are unable to scale-out, i.e., to grow
their totalprocessing capacity with the number of validators; and those that do,
compromise security or decentralization. We present OmniLedger, a novel scale-out
distributed ledger that preserves longterm security under permissionless operation.
It ensures security and correctness by using a bias-resistant public-randomness
protocol for choosing large, statistically representative shards that process
transactions, and by introducing an efficient crossshard commit protocol that
atomically handles transactions affecting multiple shards. OmniLedger also optimizes
performance via parallel intra-shard transaction processing, ledger pruning via
collectively-signed state blocks, and low-latency “trust-butverify” \r\nvalidation
for low-value transactions. An evaluation ofour experimental prototype shows that
OmniLedger’s throughput\r\nscales linearly in the number of active validators,
supporting Visa-level workloads and beyond, while confirming typical transactions
in under two seconds."

text: Characterizing the structure of membrane proteins (MPs) generally requires
extraction from their native environment, most commonly with detergents. Yet,
the physicochemical properties of detergent micelles and lipid bilayers differ
markedly and could alter the structural organization of MPs, albeit without general
rules. Dodecylphosphocholine (DPC) is the most widely used detergent for MP structure
determination by NMR, but the physiological relevance of several prominent structures
has been questioned, though indirectly, by other biophysical techniques, e.g.,
functional/thermostability assay (TSA) and molecular dynamics (MD) simulations.
Here, we resolve unambiguously this controversy by probing the functional relevance
of three different mitochondrial carriers (MCs) in DPC at the atomic level, using
an exhaustive set of solution-NMR experiments, complemented by functional/TSA
and MD data. Our results provide atomic-level insight into the structure, substrate
interaction and dynamics of the detergent–membrane protein complexes and demonstrates
cogently that, while high-resolution NMR signals can be obtained for MCs in DPC,
they systematically correspond to nonfunctional states.

text: Mycobacterium tuberculosis can remain dormant in the host, an ability that
explains the failure of many current tuberculosis treatments. Recently, the natural
products cyclomarin, ecumicin, and lassomycin have been shown to efficiently kill
Mycobacterium tuberculosis persisters. Their target is the N-terminal domain of
the hexameric AAA+ ATPase ClpC1, which recognizes, unfolds, and translocates protein
substrates, such as proteins containing phosphorylated arginine residues, to the
ClpP1P2 protease for degradation. Surprisingly, these antibiotics do not inhibit
ClpC1 ATPase activity, and how they cause cell death is still unclear. Here, using
NMR and small-angle X-ray scattering, we demonstrate that arginine-phosphate binding
to the ClpC1 N-terminal domain induces millisecond dynamics. We show that these
dynamics are caused by conformational changes and do not result from unfolding
or oligomerization of this domain. Cyclomarin binding to this domain specifically
blocked these N-terminal dynamics. On the basis of these results, we propose a
mechanism of action involving cyclomarin-induced restriction of ClpC1 dynamics,
which modulates the chaperone enzymatic activity leading eventually to cell death.

text: Membrane proteins perform a host of vital cellular functions. Deciphering
the molecular mechanisms whereby they fulfill these functions requires detailed
biophysical and structural investigations. Detergents have proven pivotal to extract
the protein from its native surroundings. Yet, they provide a milieu that departs
significantly from that of the biological membrane, to the extent that the structure,
the dynamics, and the interactions of membrane proteins in detergents may considerably
vary, as compared to the native environment. Understanding the impact of detergents
on membrane proteins is, therefore, crucial to assess the biological relevance
of results obtained in detergents. Here, we review the strengths and weaknesses
of alkyl phosphocholines (or foscholines), the most widely used detergent in solution-NMR
studies of membrane proteins. While this class of detergents is often successful
for membrane protein solubilization, a growing list of examples points to destabilizing
and denaturing properties, in particular for α-helical membrane proteins. Our
comprehensive analysis stresses the importance of stringent controls when working
with this class of detergents and when analyzing the structure and dynamics of
membrane proteins in alkyl phosphocholine detergents.

text: Solid-state near-rotary-resonance measurements of the spin–lattice relaxation
rate in the rotating frame (R1ρ) is a powerful NMR technique for studying molecular
dynamics in the microsecond time scale. The small difference between the spin-lock
(SL) and magic-angle-spinning (MAS) frequencies allows sampling very slow motions,
at the same time it brings up some methodological challenges. In this work, several
issues affecting correct measurements and analysis of 15N R1ρ data are considered
in detail. Among them are signal amplitude as a function of the difference between
SL and MAS frequencies, “dead time” in the initial part of the relaxation decay
caused by transient spin-dynamic oscillations, measurements under HORROR condition
and proper treatment of the multi-exponential relaxation decays. The multiple
15N R1ρ measurements at different SL fields and temperatures have been conducted
in 1D mode (i.e. without site-specific resolution) for a set of four different
microcrystalline protein samples (GB1, SH3, MPD-ubiquitin and cubic-PEG-ubiquitin)
to study the overall protein rocking in a crystal. While the amplitude of this
motion varies very significantly, its correlation time for all four sample is
practically the same, 30–50 μs. The amplitude of the rocking motion correlates
with the packing density of a protein crystal. It has been suggested that the
rocking motion is not diffusive but likely a jump-like dynamic process.

text: Lipopolysaccharides (LPS) are complex glycolipids forming the outside layer
of Gram-negative bacteria. Their hydrophobic and heterogeneous nature greatly
hampers their structural study in an environment similar to the bacterial surface.
We have studied LPS purified from E. coli and pathogenic P. aeruginosa with long
O-antigen polysaccharides assembled in solution as vesicles or elongated micelles.
Solid-state NMR with magic-angle spinning permitted the identification of NMR
signals arising from regions with different flexibilities in the LPS, from the
lipid components to the O-antigen polysaccharides. Atomic scale data on the LPS
enabled the study of the interaction of gentamicin antibiotic bound to P. aeruginosa
LPS, for which we could confirm that a specific oligosaccharide is involved in
the antibiotic binding. The possibility to study LPS alone and bound to a ligand
when it is assembled in membrane-like structures opens great prospects for the
investigation of proteins and antibiotics that specifically target such an important
molecule at the surface of Gram-negative bacteria.

text: The cerebral cortex contains multiple hierarchically organized areas with
distinctive cytoarchitectonical patterns, but the cellular mechanisms underlying
the emergence of this diversity remain unclear. Here, we have quantitatively investigated
the neuronal output of individual progenitor cells in the ventricular zone of
the developing mouse neocortex using a combination of methods that together circumvent
the biases and limitations of individual approaches. We found that individual
cortical progenitor cells show a high degree of stochasticity and generate pyramidal
cell lineages that adopt a wide range of laminar configurations. Mathematical
modelling these lineage data suggests that a small number of progenitor cell populations,
each generating pyramidal cells following different stochastic developmental programs,
suffice to generate the heterogenous complement of pyramidal cell lineages that
collectively build the complex cytoarchitecture of the neocortex.

text: Responsiveness—the requirement that every request to a system be eventually
handled—is one of the fundamental liveness properties of a reactive system. Average
response time is a quantitative measure for the responsiveness requirement used
commonly in performance evaluation. We show how average response time can be computed
on state-transition graphs, on Markov chains, and on game graphs. In all three
cases, we give polynomial-time algorithms.

text: 'Self-assembly is the autonomous organization of components into patterns
or structures: an essential ingredient of biology and a desired route to complex
organization1. At equilibrium, the structure is encoded through specific interactions2,3,4,5,6,7,8,
at an unfavourable entropic cost for the system. An alternative approach, widely
used by nature, uses energy input to bypass the entropy bottleneck and develop
features otherwise impossible at equilibrium9. Dissipative building blocks that
inject energy locally were made available by recent advances in colloidal science10,11
but have not been used to control self-assembly. Here we show the targeted formation
of self-powered microgears from active particles and their autonomous synchronization
into dynamical superstructures. We use a photoactive component that consumes fuel,
haematite, to devise phototactic microswimmers that form self-spinning microgears
following spatiotemporal light patterns. The gears are coupled via their chemical
clouds by diffusiophoresis12 and constitute the elementary bricks of synchronized
superstructures, which autonomously regulate their dynamics. The results are quantitatively
rationalized on the basis of a stochastic description of diffusio-phoretic oscillators
dynamically coupled by chemical gradients. Our findings harness non-equilibrium
phoretic phenomena to program interactions and direct self-assembly with fidelity
and specificity. It lays the groundwork for the autonomous construction of dynamical
architectures and functional micro-machinery.'

text: Network games are widely used as a model for selfish resource-allocation problems.
In the classicalmodel, each player selects a path connecting her source and target
vertices. The cost of traversingan edge depends on theload; namely, number of
players that traverse it. Thus, it abstracts the factthat different users may
use a resource at different times and for different durations, which playsan important
role in determining the costs of the users in reality. For example, when transmittingpackets
in a communication network, routing traffic in a road network, or processing a
task in aproduction system, actual sharing and congestion of resources crucially
depends on time.In [13], we introducedtimed network games, which add a time component
to network games.Each vertexvin the network is associated with a cost function,
mapping the load onvto theprice that a player pays for staying invfor one time
unit with this load. Each edge in thenetwork is guarded by the time intervals
in which it can be traversed, which forces the players tospend time in the vertices.
In this work we significantly extend the way time can be referred toin timed network
games. In the model we study, the network is equipped withclocks, and, as intimed
automata, edges are guarded by constraints on the values of the clocks, and their
traversalmay involve a reset of some clocks. We argue that the stronger model
captures many realisticnetworks. The addition of clocks breaks the techniques
we developed in [13] and we developnew techniques in order to show that positive
results on classic network games carry over to thestronger timed setting.

text: Estimating the homogeneous ice nucleation rate from undercooled liquid water
is crucial for understanding many important physical phenomena and technological
applications, and challenging for both experiments and theory. From a theoretical
point of view, difficulties arise due to the long time scales required, as well
as the numerous nucleation pathways involved to form ice nuclei with different
stacking disorders. We computed the homogeneous ice nucleation rate at a physically
relevant undercooling for a single-site water model, taking into account the diffuse
nature of ice–water interfaces, stacking disorders in ice nuclei, and the addition
rate of particles to the critical nucleus. We disentangled and investigated the
relative importance of all the terms, including interfacial free energy, entropic
contributions and the kinetic prefactor, that contribute to the overall nucleation
rate. Breaking down the problem into pieces not only provides physical insights
into ice nucleation, but also sheds light on the long-standing discrepancy between
different theoretical predictions, as well as between theoretical and experimental
determinations of the nucleation rate. Moreover, we pinpoint the main shortcomings
and suggest strategies to systematically improve the existing simulation methods.

text: The Gibbs free energy is the fundamental thermodynamic potential underlying
the relative stability of different states of matter under constant-pressure conditions.
However, computing this quantity from atomic-scale simulations is far from trivial,
so the potential energy of a system is often used as a proxy. In this paper, we
use a combination of thermodynamic integration methods to accurately evaluate
the Gibbs free energies associated with defects in crystals, including the vacancy
formation energy in bcc iron, and the stacking fault energy in fcc nickel, iron,
and cobalt. We quantify the importance of entropic and anharmonic effects in determining
the free energies of defects at high temperatures, and show that the potential
energy approximation as well as the harmonic approximation may produce inaccurate
or even qualitatively wrong results. Our calculations manifest the necessity to
employ accurate free energy methods such as thermodynamic integration to estimate
the stability of crystallographic defects at high temperatures.

text: 'More than 100 years after Grigg’s influential analysis of species’ borders,
the causes of limits to species’ ranges still represent a puzzle that has never
been understood with clarity. The topic has become especially important recently
as many scientists have become interested in the potential for species’ ranges
to shift in response to climate change—and yet nearly all of those studies fail
to recognise or incorporate evolutionary genetics in a way that relates to theoretical
developments. I show that range margins can be understood based on just two measurable
parameters: (i) the fitness cost of dispersal—a measure of environmental heterogeneity—and
(ii) the strength of genetic drift, which reduces genetic diversity. Together,
these two parameters define an ‘expansion threshold’: adaptation fails when genetic
drift reduces genetic diversity below that required for adaptation to a heterogeneous
environment. When the key parameters drop below this expansion threshold locally,
a sharp range margin forms. When they drop below this threshold throughout the
species’ range, adaptation collapses everywhere, resulting in either extinction
or formation of a fragmented metapopulation. Because the effects of dispersal
differ fundamentally with dimension, the second parameter—the strength of genetic
drift—is qualitatively different compared to a linear habitat. In two-dimensional
habitats, genetic drift becomes effectively independent of selection. It decreases
with ‘neighbourhood size’—the number of individuals accessible by dispersal within
one generation. Moreover, in contrast to earlier predictions, which neglected
evolution of genetic variance and/or stochasticity in two dimensions, dispersal
into small marginal populations aids adaptation. This is because the reduction
of both genetic and demographic stochasticity has a stronger effect than the cost
of dispersal through increased maladaptation. The expansion threshold thus provides
a novel, theoretically justified, and testable prediction for formation of the
range margin and collapse of the species’ range.'

text: The restricted planar elliptic three body problem (RPETBP) describes the motion
of a massless particle (a comet or an asteroid) under the gravitational field
of two massive bodies (the primaries, say the Sun and Jupiter) revolving around
their center of mass on elliptic orbits with some positive eccentricity. The aim
of this paper is to show the existence of orbits whose angular momentum performs
arbitrary excursions in a large region. In particular, there exist diffusive orbits,
that is, with a large variation of angular momentum. The leading idea of the proof
consists in analyzing parabolic motions of the comet. By a well-known result of
McGehee, the union of future (resp. past) parabolic orbits is an analytic manifold
P+ (resp. P−). In a properly chosen coordinate system these manifolds are stable
(resp. unstable) manifolds of a manifold at infinity P∞, which we call the manifold
at parabolic infinity. On P∞ it is possible to define two scattering maps, which
contain the map structure of the homoclinic trajectories to it, i.e. orbits parabolic
both in the future and the past. Since the inner dynamics inside P∞ is trivial,
two different scattering maps are used. The combination of these two scattering
maps permits the design of the desired diffusive pseudo-orbits. Using shadowing
techniques and these pseudo orbits we show the existence of true trajectories
of the RPETBP whose angular momentum varies in any predetermined fashion.

text: 'The Birkhoff conjecture says that the boundary of a strictly convex integrable
billiard table is necessarily an ellipse. In this article, we consider a stronger
notion of integrability, namely integrability close to the boundary, and prove
a local version of this conjecture: a small perturbation of an ellipse of small
eccentricity which preserves integrability near the boundary, is itself an ellipse.
This extends the result in Avila et al. (Ann Math 184:527–558, ADK16), where integrability
was assumed on a larger set. In particular, it shows that (local) integrability
near the boundary implies global integrability. One of the crucial ideas in the
proof consists in analyzing Taylor expansion of the corresponding action-angle
coordinates with respect to the eccentricity parameter, deriving and studying
higher order conditions for the preservation of integrable rational caustics.'

with rational caustics is dense. More precisely, the set of billiard boundaries
with caustics of rotation number 1/q is polynomially sense in the smooth case,
and exponentially dense in the analytic case.

text: Chaperonins are ubiquitous protein assemblies present in bacteria, eukaryota,
and archaea, facilitating the folding of proteins, preventing protein aggregation,
and thus participating in maintaining protein homeostasis in the cell. During
their functional cycle, they bind unfolded client proteins inside their double
ring structure and promote protein folding by closing the ring chamber in an adenosine
5′-triphosphate (ATP)–dependent manner. Although the static structures of fully
open and closed forms of chaperonins were solved by x-ray crystallography or electron
microscopy, elucidating the mechanisms of such ATP-driven molecular events requires
studying the proteins at the structural level under working conditions. We introduce
an approach that combines site-specific nuclear magnetic resonance observation
of very large proteins, enabled by advanced isotope labeling methods, with an
in situ ATP regeneration system. Using this method, we provide functional insight
into the 1-MDa large hsp60 chaperonin while processing client proteins and reveal
how nucleotide binding, hydrolysis, and release control switching between closed
and open states. While the open conformation stabilizes the unfolded state of
client proteins, the internalization of the client protein inside the chaperonin
cavity speeds up its functional cycle. This approach opens new perspectives to
study structures and mechanisms of various ATP-driven biological machineries in
the heat of action.

text: The exchange of metabolites between the mitochondrial matrix and the cytosol
depends on β-barrel channels in the outer membrane and α-helical carrier proteins
in the inner membrane. The essential translocase of the inner membrane (TIM) chaperones
escort these proteins through the intermembrane space, but the structural and
mechanistic details remain elusive. We have used an integrated structural biology
approach to reveal the functional principle of TIM chaperones. Multiple clamp-like
binding sites hold the mitochondrial membrane proteins in a translocation-competent
elongated form, thus mimicking characteristics of co-translational membrane insertion.
The bound preprotein undergoes conformational dynamics within the chaperone binding
clefts, pointing to a multitude of dynamic local binding events. Mutations in
these binding sites cause cell death or growth defects associated with impairment
of carrier and β-barrel protein biogenesis. Our work reveals how a single mitochondrial
“transfer-chaperone” system is able to guide α-helical and β-barrel membrane proteins
in a “nascent chain-like” conformation through a ribosome-free compartment.

text: For any strictly convex planar domain Ω ⊂ R2 with a C∞ boundary one can associate
an infinite sequence of spectral invariants introduced by Marvizi–Merlose [5].
These invariants can generically be determined using the spectrum of the Dirichlet
problem of the Laplace operator. A natural question asks if this collection is
sufficient to determine Ω up to isometry. In this paper we give a counterexample,
namely, we present two nonisometric domains Ω and Ω¯ with the same collection
of Marvizi–Melrose invariants. Moreover, each domain has countably many periodic
orbits {Sn}n≥1 (resp. {S¯n}n⩾1) of period going to infinity such that Sn and S¯n
have the same period and perimeter for each n.

text: The development of strategies to assemble microscopic machines from dissipative
building blocks are essential on the route to novel active materials. We recently
demonstrated the hierarchical self-assembly of phoretic microswimmers into self-spinning
microgears and their synchronization by diffusiophoretic interactions [Aubret
et al., Nat. Phys., 2018]. In this paper, we adopt a pedagogical approach and
expose our strategy to control self-assembly and build machines using phoretic
phenomena. We notably introduce Highly Inclined Laminated Optical sheets microscopy
(HILO) to image and characterize anisotropic and dynamic diffusiophoretic interactions,
which cannot be performed by conventional fluorescence microscopy. The dynamics
of a (haematite) photocatalytic material immersed in (hydrogen peroxide) fuel
under various illumination patterns is first described and quantitatively rationalized
by a model of diffusiophoresis, the migration of a colloidal particle in a concentration
gradient. It is further exploited to design phototactic microswimmers that direct
towards the high intensity of light, as a result of the reorientation of the haematite
in a light gradient. We finally show the assembly of self-spinning microgears
from colloidal microswimmers and carefully characterize the interactions using
HILO techniques. The results are compared with analytical and numerical predictions
and agree quantitatively, stressing the important role played by concentration
gradients induced by chemical activity to control and design interactions. Because
the approach described hereby is generic, this works paves the way for the rational
design of machines by controlling phoretic phenomena.

text: The novel electronic state of the canted antiferromagnetic (AFM) insulator,
strontium iridate (Sr2IrO4) has been well described by the spin-orbit-entangled
isospin Jeff = 1/2, but the role of isospin in transport phenomena remains poorly
understood. In this study, antiferromagnet-based spintronic functionality is demonstrated
by combining unique characteristics of the isospin state in Sr2IrO4. Based on
magnetic and transport measurements, large and highly anisotropic magnetoresistance
(AMR) is obtained by manipulating the antiferromagnetic isospin domains. First-principles
calculations suggest that electrons whose isospin directions are strongly coupled
to in-plane net magnetic moment encounter the isospin mismatch when moving across
antiferromagnetic domain boundaries, which generates a high resistance state.
By rotating a magnetic field that aligns in-plane net moments and removes domain
boundaries, the macroscopically-ordered isospins govern dynamic transport through
the system, which leads to the extremely angle-sensitive AMR. As with this work
that establishes a link between isospins and magnetotransport in strongly spin-orbit-coupled
AFM Sr2IrO4, the peculiar AMR effect provides a beneficial foundation for fundamental
and applied research on AFM spintronics.

text: We report the temperature-dependent resistivity ρ(T) of chalcogenide NiS2-xSex
(x = 0.1) using hydrostatic pressure as a control parameter in the temperature
range of 4–300 K. The insulating behavior of ρ(T) survives at low temperatures
in the pressure regime below 7.5 kbar, whereas a clear insulator-to-metallic transition
is observed above 7.5 kbar. Two types of magnetic transitions, from the paramagnetic
(PM) to the antiferromagnetic (AFM) state and from the AFM state to the weak ferromagnetic
(WF) state, were evaluated and confirmed by magnetization measurement. According
to the temperature–pressure phase diagram, the WF phase survives up to 7.5 kbar,
and the transition temperature of the WF transition decreases as the pressure
increases, whereas the metal–insulator transition temperature increases up to
9.4 kbar. We analyzed the metallic behavior and proposed Fermi-liquid behavior
of NiS1.9Se0.1.

text: In this study we investigate the scaling of precipitation extremes with temperature
in the Mediterranean region by assessing against observations the present day
and future regional climate simulations performed in the frame of the HyMeX and
MED-CORDEX programs. Over the 1979–2008 period, despite differences in quantitative
precipitation simulation across the various models, the change in precipitation
extremes with respect to temperature is robust and consistent. The spatial variability
of the temperature–precipitation extremes relationship displays a hook shape across
the Mediterranean, with negative slope at high temperatures and a slope following
Clausius–Clapeyron (CC)-scaling at low temperatures. The temperature at which
the slope of the temperature–precipitation extreme relation sharply changes (or
temperature break), ranges from about 20 °C in the western Mediterranean to <10
°C in Greece. In addition, this slope is always negative in the arid regions of
the Mediterranean. The scaling of the simulated precipitation extremes is insensitive
to ocean–atmosphere coupling, while it depends very weakly on the resolution at
high temperatures for short precipitation accumulation times. In future climate
scenario simulations covering the 2070–2100 period, the temperature break shifts
to higher temperatures by a value which is on average the mean regional temperature
change due to global warming. The slope of the simulated future temperature–precipitation
extremes relationship is close to CC-scaling at temperatures below the temperature
break, while at high temperatures, the negative slope is close, but somewhat flatter
or steeper, than in the current climate depending on the model. Overall, models
predict more intense precipitation extremes in the future. Adjusting the temperature–precipitation
extremes relationship in the present climate using the CC law and the temperature
shift in the future allows the recovery of the temperature–precipitation extremes
relationship in the future climate. This implies negligible regional changes of
relative humidity in the future despite the large warming and drying over the
Mediterranean. This suggests that the Mediterranean Sea is the primary source
of moisture which counteracts the drying and warming impacts on relative humidity
in parts of the Mediterranean region.

text: Several studies have shown the existence of a critical latitude where the
dissipation of internal tides is strongly enhanced. Internal tides are internal
waves generated by barotropic tidal currents impinging rough topography at the
seafloor. Their dissipation and concomitant diapycnal mixing are believed to be
important for water masses and the large‐scale ocean circulation. The purpose
of this study is to clarify the physical processes at the origin of this strong
latitudinal dependence of tidal energy dissipation. We find that different mechanisms
are involved equatorward and poleward of the critical latitude. Triadic resonant
instabilities are responsible for the dissipation of internal tides equatorward
of the critical latitude. In particular, a dominant triad involving the primary
internal tide and near‐inertial waves is key. At the critical latitude, the peak
of energy dissipation is explained by both increased instability growth rates,
and smaller scales of secondary waves thus more prone to break and dissipate their
energy. Surprisingly, poleward of the critical latitude, the generation of evanescent
waves appears to be crucial. Triadic instabilities have been widely studied, but
the transfer of energy to evanescent waves has received comparatively little attention.
Our work suggests that the nonlinear transfer of energy from the internal tide
to evanescent waves (corresponding to the 2f‐pump mechanism described by Young
et al., 2008, https://doi.org/10.1017/S0022112008001742) is an efficient mechanism
to dissipate internal tide energy near and poleward of the critical latitude.
The theoretical results are confirmed in idealized high‐resolution numerical simulations
of a barotropic M2 tide impinging sinusoidal topography in a linearly stratified
fluid.

text: Idealized simulations of tropical moist convection have revealed that clouds
can spontaneously clump together in a process called self-aggregation. This results
in a state where a moist cloudy region with intense deep convection is surrounded
by extremely dry subsiding air devoid of deep convection. Because of the idealized
settings of the simulations where it was discovered, the relevance of self-aggregation
to the real world is still debated. Here, we show that self-aggregation feedbacks
play a leading-order role in the spontaneous genesis of tropical cyclones in cloud-resolving
simulations. Those feedbacks accelerate the cyclogenesis process by a factor of
2, and the feedbacks contributing to the cyclone formation show qualitative and
quantitative agreement with the self-aggregation process. Once the cyclone is
formed, wind-induced surface heat exchange (WISHE) effects dominate, although
we find that self-aggregation feedbacks have a small but nonnegligible contribution
to the maintenance of the mature cyclone. Our results suggest that self-aggregation,
and the framework developed for its study, can help shed more light into the physical
processes leading to cyclogenesis and cyclone intensification. In particular,
our results point out the importance of the longwave radiative cooling outside
the cyclone.

text: The DEMETER (DME) DNA glycosylase catalyzes genome-wide DNA demethylation
and is required for endosperm genomic imprinting and embryo viability. Targets
of DME-mediated DNA demethylation reside in small, euchromatic, AT-rich transposons
and at the boundaries of large transposons, but how DME interacts with these diverse
chromatin states is unknown. The STRUCTURE SPECIFIC RECOGNITION PROTEIN 1 (SSRP1)
subunit of the chromatin remodeler FACT (facilitates chromatin transactions),
was previously shown to be involved in the DME-dependent regulation of genomic
imprinting in Arabidopsis endosperm. Therefore, to investigate the interaction
between DME and chromatin, we focused on the activity of the two FACT subunits,
SSRP1 and SUPPRESSOR of TY16 (SPT16), during reproduction in Arabidopsis. We found
that FACT colocalizes with nuclear DME in vivo, and that DME has two classes of
target sites, the first being euchromatic and accessible to DME, but the second,
representing over half of DME targets, requiring the action of FACT for DME-mediated
DNA demethylation genome-wide. Our results show that the FACT-dependent DME targets
are GC-rich heterochromatin domains with high nucleosome occupancy enriched with
H3K9me2 and H3K27me1. Further, we demonstrate that heterochromatin-associated
linker histone H1 specifically mediates the requirement for FACT at a subset of
DME-target loci. Overall, our results demonstrate that FACT is required for DME
targeting by facilitating its access to heterochromatin.

text: Electrostatic charging of insulating fine particles can be responsible for
numerous phenomena ranging from lightning in volcanic plumes to dust explosions.
However, even basic aspects of how fine particles become charged are still unclear.
Studying particle charging is challenging because it usually involves the complexities
associated with many-particle collisions. To address these issues, we introduce
a method based on acoustic levitation, which makes it possible to initiate sequences
of repeated collisions of a single submillimeter particle with a flat plate, and
to precisely measure the particle charge in situ after each collision. We show
that collisional charge transfer between insulators is dependent on the hydrophobicity
of the contacting surfaces. We use glass, which we modify by attaching nonpolar
molecules to the particle, the plate, or both. We find that hydrophilic surfaces
develop significant positive charges after contacting hydrophobic surfaces. Moreover,
we demonstrate that charging between a hydrophilic and a hydrophobic surface is
suppressed in an acidic environment and enhanced in a basic one. Application of
an electric field during each collision is found to modify the charge transfer,
again depending on surface hydrophobicity. We discuss these results within the
context of contact charging due to ion transfer, and we show that they lend strong
support to OH− ions as the charge carriers.

text: Let P be a graph property which is preserved by removal of edges, and consider
the random graph process that starts with the empty n-vertex graph and then adds
edges one-by-one, each chosen uniformly at random subject to the constraint that
P is not violated. These types of random processes have been the subject of extensive
research over the last 20 years, having striking applications in extremal combinatorics,
and leading to the discovery of important probabilistic tools. In this paper we
consider the k-matching-free process, where P is the property of not containing
a matching of size k. We are able to analyse the behaviour of this process for
a wide range of values of k; in particular we prove that if k=o(n) or if n−2k=o(n−−√/logn)
then this process is likely to terminate in a k-matching-free graph with the maximum
possible number of edges, as characterised by Erdős and Gallai. We also show that
these bounds on k are essentially best possible, and we make a first step towards
understanding the behaviour of the process in the intermediate regime.

text: Let D(n,p) be the random directed graph on n vertices where each of the n(n-1)
possible arcs is present independently with probability p. A celebrated result
of Frieze shows that if p≥(logn+ω(1))/n then D(n,p) typically has a directed Hamilton
cycle, and this is best possible. In this paper, we obtain a strengthening of
this result, showing that under the same condition, the number of directed Hamilton
cycles in D(n,p) is typically n!(p(1+o(1)))n. We also prove a hitting-time version
of this statement, showing that in the random directed graph process, as soon
as every vertex has in-/out-degrees at least 1, there are typically n!(logn/n(1+o(1)))n

text: An intercalate in a Latin square is a 2×2 Latin subsquare. Let N be the number
of intercalates in a uniformly random n×n Latin square. We prove that asymptotically
almost surely N≥(1−o(1))n2/4, and that EN≤(1+o(1))n2/2 (therefore asymptotically
almost surely N≤fn2 for any f→∞). This significantly improves the previous best
lower and upper bounds. We also give an upper tail bound for the number of intercalates
in two fixed rows of a random Latin square. In addition, we discuss a problem
of Linial and Luria on low-discrepancy Latin squares.

text: We say a family of sets is intersecting if any two of its sets intersect,
and we say it is trivially intersecting if there is an element which appears in
every set of the family. In this paper we study the maximum size of a non-trivially
intersecting family in a natural “multi-part” setting. Here the ground set is
divided into parts, and one considers families of sets whose intersection with
each part is of a prescribed size. Our work is motivated by classical results
in the single-part setting due to Erdős, Ko and Rado, and Hilton and Milner, and
by a theorem of Frankl concerning intersecting families in this multi-part setting.
In the case where the part sizes are sufficiently large we determine the maximum
size of a non-trivially intersecting multi-part family, disproving a conjecture
of Alon and Katona.

text: We investigate the thermodynamics and kinetics of a hydrogen interstitial
in magnetic α-iron, taking account of the quantum fluctuations of the proton as
well as the anharmonicities of lattice vibrations and hydrogen hopping. We show
that the diffusivity of hydrogen in the lattice of bcc iron deviates strongly
from an Arrhenius behavior at and below room temperature. We compare a quantum
transition state theory to explicit ring polymer molecular dynamics in the calculation
of diffusivity. We then address the trapping of hydrogen by a vacancy as a prototype
lattice defect. By a sequence of steps in a thought experiment, each involving
a thermodynamic integration, we are able to separate out the binding free energy
of a proton to a defect into harmonic and anharmonic, and classical and quantum
contributions. We find that about 30% of a typical binding free energy of hydrogen
to a lattice defect in iron is accounted for by finite temperature effects, and
about half of these arise from quantum proton fluctuations. This has huge implications
for the comparison between thermal desorption and permeation experiments and standard
electronic structure theory. The implications are even greater for the interpretation
of muon spin resonance experiments.

text: The curvature dependence of interfacial free energy, which is crucial in quantitatively
predicting nucleation kinetics and the stability of bubbles and droplets, is quantified
by the Tolman length δ. For solid-liquid interfaces, however, δ has never been
computed directly due to various theoretical and practical challenges. Here we
perform a direct evaluation of the Tolman length from atomistic simulations of
a solid-liquid planar interface in out-of-equilibrium conditions, by first computing
the surface tension from the amplitude of thermal capillary fluctuations of a
localized version of the Gibbs dividing surface and by then calculating how much
the surface energy changes when it is defined relative to the equimolar dividing
surface. We computed δ for a model potential, and found a good agreement with
the values indirectly inferred from nucleation simulations. The agreement not
only validates our approach but also suggests that the nucleation free energy
of the system can be perfectly described using classical nucleation theory if
the Tolman length is taken into account.

text: We present a field-data rich modelling analysis to reconstruct the climatic
forcing, glacier response, and runoff generation from a high-elevation catchment
in central Chile over the period 2000–2015 to provide insights into the differing
contributions of debris-covered and debris-free glaciers under current and future
changing climatic conditions. Model simulations with the physically based glacio-hydrological
model TOPKAPI-ETH reveal a period of neutral or slightly positive mass balance
between 2000 and 2010, followed by a transition to increasingly large annual mass
losses, associated with a recent mega drought. Mass losses commence earlier, and
are more severe, for a heavily debris-covered glacier, most likely due to its
strong dependence on snow avalanche accumulation, which has declined in recent
years. Catchment runoff shows a marked decreasing trend over the study period,
but with high interannual variability directly linked to winter snow accumulation,
and high contribution from ice melt in dry periods and drought conditions. The
study demonstrates the importance of incorporating local-scale processes such
as snow avalanche accumulation and spatially variable debris thickness, in understanding
the responses of different glacier types to climate change. We highlight the increased
dependency of runoff from high Andean catchments on the diminishing resource of
glacier ice during dry years.

text: Snow depth patterns over glaciers are controlled by precipitation, snow redistribution
due to wind and avalanches, and the exchange of energy with the atmosphere that
determines snow ablation. While many studies have advanced the understanding of
ablation processes, less is known about winter snow patterns and their variability
over glaciers. We analyze snow depth on Haut Glacier d'Arolla, Switzerland, in
the two winter seasons 2006–2007 and 2010–2011 to (1) understand whether snow
depth over an alpine glacier at the end of the accumulation season exhibits a
behavior similar to the one observed on single slopes and vegetated areas; and
(2) investigate the snow pattern consistency over the two accumulation seasons.
We perform this analysis on a data set of high-resolution lidar-derived snow depth
using variograms and fractal parameters. Our first main result is that snow depth
patterns on the glacier exhibit a multiscale behavior, with a scale break around
20 m after which the fractal dimension increases, indicating more autocorrelated
structure before the scale break than after. Second, this behavior is consistent
over the two years, with fractal parameters and their spatial variability almost
constant in the two seasons. We also show that snow depth patterns exhibit a distinct
behavior in the glacier tongue and the upper catchment, with longer correlation
distances on the tongue in the direction of the main winds, suggesting spatial
distinctions that are likely induced by different processes and that should be

text: Glaciers in the high mountains of Asia provide an important water resource
for millions of people. Many of these glaciers are partially covered by rocky
debris, which protects the ice from solar radiation and warm air. However, studies
have found that the surface of these debris-covered glaciers is actually lowering
as fast as glaciers without debris. Water ponded on the surface of the glaciers
may be partially responsible, as water can absorb atmospheric energy very efficiently.
However, the overall effect of these ponds has not been thoroughly assessed yet.
We study a valley in Nepal for which we have extensive weather measurements, and
we use a numerical model to calculate the energy absorbed by ponds on the surface
of the glaciers over 6 months. As we have not observed each individual pond thoroughly,
we run the model 5,000 times with different setups. We find that ponds are extremely
important for glacier melt and absorb energy 14 times as quickly as the debris-covered
ice. Although the ponds account for 1% of the glacier area covered by rocks, and
only 0.3% of the total glacier area, they absorb enough energy to account for
one eighth of the whole valley's ice loss.

text: Supraglacial ice cliffs exist on debris-covered glaciers worldwide, but despite
their importance as melt hot spots, their life cycle is little understood. Early
field observations had advanced a hypothesis of survival of north-facing and disappearance
of south-facing cliffs, which is central for predicting the contribution of cliffs
to total glacier mass losses. Their role as windows of energy transfer suggests
they may explain the anomalously high mass losses of debris-covered glaciers in
High Mountain Asia (HMA) despite the insulating debris, currently at the center
of a debated controversy. We use a 3D model of cliff evolution coupled to very
high-resolution topographic data to demonstrate that ice cliffs facing south (in
the Northern Hemisphere) disappear within a few months due to enhanced solar radiation
receipts and that aspect is the key control on cliffs evolution. We reproduce
continuous flattening of south-facing cliffs, a result of their vertical gradient
of incoming solar radiation and sky view factor. Our results establish that only
north-facing cliffs are recurrent features and thus stable contributors to the
melting of debris-covered glaciers. Satellite observations and mass balance modeling
confirms that few south-facing cliffs of small size exist on the glaciers of Langtang,
and their contribution to the glacier volume losses is very small (∼1%). This
has major implications for the mass balance of HMA debris-covered glaciers as
it provides the basis for new parameterizations of cliff evolution and distribution
to constrain volume losses in a region where glaciers are highly relevant as water
sources for millions of people.

text: Ice cliffs within a supraglacial debris cover have been identified as a source
for high ablation relative to the surrounding debris-covered area. Due to their
small relative size and steep orientation, ice cliffs are difficult to detect
using nadir-looking space borne sensors. The method presented here uses surface
slopes calculated from digital elevation model (DEM) data to map ice cliff geometry
and produce an ice cliff probability map. Surface slope thresholds, which can
be sensitive to geographic location and/or data quality, are selected automatically.
The method also attempts to include area at the (often narrowing) ends of ice
cliffs which could otherwise be neglected due to signal saturation in surface
slope data. The method was calibrated in the eastern Alaska Range, Alaska, USA,
against a control ice cliff dataset derived from high-resolution visible and thermal
data. Using the same input parameter set that performed best in Alaska, the method
was tested against ice cliffs manually mapped in the Khumbu Himal, Nepal. Our
results suggest the method can accommodate different glaciological settings and
different DEM data sources without a data intensive (high-resolution, multi-data
source) recalibration.

text: Focused ion beams perfectly suit for patterning two-dimensional (2D) materials,
but the optimization of irradiation parameters requires full microscopic understanding
of defect production mechanisms. In contrast to freestanding 2D systems, the details
of damage creation in supported 2D materials are not fully understood, whereas
the majority of experiments have been carried out for 2D targets deposited on
substrates. Here, we suggest a universal and computationally efficient scheme
to model the irradiation of supported 2D materials, which combines analytical
potential molecular dynamics with Monte Carlo simulations and makes it possible
to independently assess the contributions to the damage from backscattered ions
and atoms sputtered from the substrate. Using the scheme, we study the defect
production in graphene and MoS2 sheets, which are the two most important and wide-spread
2D materials, deposited on a SiO2 substrate. For helium and neon ions with a wide
range of initial ion energies including those used in a commercial helium ion
microscope (HIM), we demonstrate that depending on the ion energy and mass, the
defect production in 2D systems can be dominated by backscattered ions and sputtered
substrate atoms rather than by the direct ion impacts and that the amount of damage
in 2D materials heavily depends on whether a substrate is present or not. We also
study the factors which limit the spatial resolution of the patterning process.
Our results, which agree well with the available experimental data, provide not
only insights into defect production but also quantitative information, which
can be used for the minimization of damage during imaging in HIM or optimization
of the patterning process.

text: Efficient molecular switching in confined spaces is critical for the successful
development of artificial molecular machines. However, molecular switching events
often entail large structural changes and therefore require conformational freedom,
which is typically limited under confinement conditions. Here, we investigated
the behavior of azobenzene—the key building block of light-controlled molecular
machines—in a confined environment that is flexible and can adapt its shape to
that of the bound guest. To this end, we encapsulated several structurally diverse
azobenzenes within the cavity of a flexible, water-soluble coordination cage,
and investigated their light-responsive behavior. Using UV/Vis absorption spectroscopy
and a combination of NMR methods, we showed that each of the encapsulated azobenzenes
exhibited distinct switching properties. An azobenzene forming a 1:1 host–guest
inclusion complex could be efficiently photoisomerized in a reversible fashion.
In contrast, successful switching in inclusion complexes incorporating two azobenzene
guests was dependent on the availability of free cages in the system, and it involved
reversible trafficking of azobenzene between the cages. In the absence of extra
cages, photoswitching was either suppressed or it involved expulsion of azobenzene
from the cage and consequently its precipitation from the solution. This finding
was utilized to develop an information storage medium in which messages could
be written and erased in a reversible fashion using light.

text: Confining molecules to volumes only slightly larger than the molecules themselves
can profoundly alter their properties. Molecular switches—entities that can be
toggled between two or more forms upon exposure to an external stimulus—often
require conformational freedom to isomerize. Therefore, placing these switches
in confined spaces can render them non-operational. To preserve the switchability
of these species under confinement, we work with a water-soluble coordination
cage that is flexible enough to adapt its shape to the conformation of the encapsulated
guest. We show that owing to its flexibility, the cage is not only capable of
accommodating—and solubilizing in water—several light-responsive spiropyran-based
molecular switches, but, more importantly, it also provides an environment suitable
for the efficient, reversible photoisomerization of the bound guests. Our findings
pave the way towards studying various molecular switching processes in confined
environments.

text: Confining organic molecules to the surfaces of inorganic nanoparticles can
induce intermolecular interactions between them, which can affect the composition
of the mixed self-assembled monolayers obtained by co-adsorption from solution
of two different molecules. Two thiolated ligands (a dialkylviologen and a zwitterionic
sulfobetaine) that can interact with each other electrostatically were coadsorbed
onto gold nanoparticles. The nanoparticles favor a narrow range of ratios of these
two molecules that is largely independent of the molar ratio in solution. Changing
the solution molar ratio of the two ligands by a factor of 5 000 affects the on-nanoparticle
ratio of these ligands by only threefold. This behavior is reminiscent of the
formation of insoluble inorganic salts (such as AgCl), which similarly compensate
positive and negative charges upon crystallizing. Our results pave the way towards
developing well-defined hybrid organic–inorganic nanostructures.

text: 'Dissipative self-assembly leads to structures and materials that exist away
from equilibrium by continuously exchanging energy and materials with the external
environment. Although this mode of self-assembly is ubiquitous in nature, where
it gives rise to functions such as signal processing, motility, self-healing,
self-replication, and ultimately life, examples of dissipative self-assembly processes
in man-made systems are few and far between. Herein, recent progress in developing
diverse synthetic dissipative self-assembly systems is discussed. The systems
reported thus far can be categorized into three classes, in which: i) the fuel
chemically modifies the building blocks, thus triggering their self-assembly,
ii) the fuel acts as a template interacting with the building blocks noncovalently,
and iii) transient states are induced by the addition of two mutually exclusive
stimuli. These early studies give rise to materials that would be difficult to
obtain otherwise, including hydrogels with programmable lifetimes, vesicular nanoreactors,
and membranes exhibiting transient conductivity.'

text: Stars stripped of their hydrogen-rich envelope through interaction with a
binary companion are generally not considered when accounting for ionizing radiation
from stellar populations, despite the expectation that stripped stars emit hard
ionizing radiation, form frequently, and live 10–100 times longer than single
massive stars. We compute the first grid of evolutionary and spectral models specially
made for stars stripped in binaries for a range of progenitor masses (2–20 M⊙)
and metallicities ranging from solar to values representative for pop II stars.
For stripped stars with masses in the range 0.3–7 M⊙, we find consistently high
effective temperatures (20 000–100 000 K, increasing with mass), small radii (0.2–1
R⊙), and high bolometric luminosities, comparable to that of their progenitor
before stripping. The spectra show a continuous sequence that naturally bridges
subdwarf-type stars at the low-mass end and Wolf-Rayet-like spectra at the high-mass
end. For intermediate masses we find hybrid spectral classes showing a mixture
of absorption and emission lines. These appear for stars with mass-loss rates
of 10−8−10−6 M⊙ yr−1, which have semi-transparent atmospheres. At low metallicity,
substantial hydrogen-rich layers are left at the surface and we predict spectra
that resemble O-type stars instead. We obtain spectra undistinguishable from subdwarfs
for stripped stars with masses up to 1.7 M⊙, which questions whether the widely
adopted canonical value of 0.47 M⊙ is uniformly valid. Only a handful of stripped
stars of intermediate mass have currently been identified observationally. Increasing
this sample will provide necessary tests for the physics of interaction, internal
mixing, and stellar winds. We use our model spectra to investigate the feasibility
to detect stripped stars next to an optically bright companion and recommend systematic
searches for their UV excess and possible emission lines, most notably HeII λ4686
in the optical and HeII λ1640 in the UV. Our models are publicly available for
further investigations or inclusion in spectral synthesis simulations.

text: Stripped-envelope stars form in binary systems after losing mass through Roche-lobe
overflow. They bear astrophysical significance as sources of UV and ionizing radiation
in older stellar populations and, if sufficiently massive, as stripped supernova
progenitors. Binary evolutionary models predict that they are common, but only
a handful of subdwarfs with B-type companions are known. The question is whether
a large population of such systems has evaded detection as a result of biases,
or whether the model predictions are wrong. We reanalyze the well-studied post-interaction
binary φ Persei. Recently, new data have improved the orbital solution of the
system, which contains an ~1.2M⊙ stripped-envelope star and a rapidly rotating
~9.6M⊙ Be star. We compare with an extensive grid of evolutionary models using
a Bayesian approach and constrain the initial masses of the progenitor to 7.2
± 0.4M⊙ for the stripped star and 3.8 ± 0.4M⊙ for the Be star. The system must
have evolved through near-conservative mass transfer. These findings are consistent
with earlier studies. The age we obtain, 57 ± 9 Myr, is in excellent agreement
with the age of the α Persei cluster. We note that neither star was initially
massive enough to produce a core-collapse supernova, but mass exchange pushed
the Be star above the mass threshold. We find that the subdwarf is overluminous
for its mass by almost an order of magnitude, compared to the expectations for
a helium core burning star. We can only reconcile this if the subdwarf resides
in a late phase of helium shell burning, which lasts only 2–3% of the total lifetime
as a subdwarf. Assuming continuous star formation implies that up to ~50 less
evolved, dimmer subdwarfs exist for each system similar to φ Persei, but have
evaded detection so far. Our findings can be interpreted as a strong indication
that a substantial population of stripped-envelope stars indeed exists, but has
so far evaded detection because of observational biases and lack of large-scale
systematic searches.

text: Recent surveys of the Magellanic Clouds have revealed a subtype of Wolf–Rayet
(WR) star with peculiar properties. WN3/O3 spectra exhibit both WR-like emission
and O3 V-like absorption – but at lower luminosity than O3 V or WN stars. We examine
the projected spatial distribution of WN3/O3 stars in the Large Magellanic Cloud
as compared to O-type stars. Surprisingly, WN3/O3 stars are among the most isolated
of all classes of massive stars; they have a distribution similar to red supergiants
dominated by initial masses of 10–15 M⊙, and are far more dispersed than classical
WR stars or luminous blue variables. Their lack of association with clusters of
O-type stars suggests strongly that WN3/O3 stars are not the descendants of single
massive stars (30 M⊙ or above). Instead, they are likely products of interacting
binaries at lower initial mass (10–18 M⊙). Comparison with binary models suggests
a probable origin with primaries in this mass range that were stripped of their
H envelopes through non-conservative mass transfer by a low-mass secondary. We
show that model spectra and positions on the Hertzsprung–Russell diagram for binary-stripped
stars are consistent with WN3/O3 stars. Monitoring radial velocities with high-resolution
spectra can test for low-mass companions or runaway velocities. With lower initial
mass and environments that avoid very massive stars, the WN3/O3 stars fit expectations
for progenitors of Type Ib and possibly Type Ibn supernovae.

text: 'A drawing of a graph on a surface is independently even if every pair of
nonadjacent edges in the drawing crosses an even number of times. The ℤ2-genus
of a graph G is the minimum g such that G has an independently even drawing on
the orientable surface of genus g. An unpublished result by Robertson and Seymour
implies that for every t, every graph of sufficiently large genus contains as
a minor a projective t × t grid or one of the following so-called t-Kuratowski
graphs: K3, t, or t copies of K5 or K3,3 sharing at most 2 common vertices. We
show that the ℤ2-genus of graphs in these families is unbounded in t; in fact,
equal to their genus. Together, this implies that the genus of a graph is bounded
from above by a function of its ℤ2-genus, solving a problem posed by Schaefer
and Štefankovič, and giving an approximate version of the Hanani-Tutte theorem
on orientable surfaces.'

text: "Molecular chirality plays an essential role in most biochemical processes.
The observation and quantification of chirality-sensitive signals, however, remains
extremely challenging, especially on ultrafast timescales and in dilute media.
Here, we describe the experimental realization of an all-optical and ultrafast
scheme for detecting chiral dynamics in molecules. This technique is based on
high-harmonic generation by a combination of two-color counterrotating femtosecond
laser pulses with polarization states tunable from linear to circular. We demonstrate
two different implementations of chiral-sensitive high-harmonic spectroscopy on
an ensemble of randomly oriented methyloxirane molecules in the gas phase. Using
two elliptically polarized fields, we observe that the ellipticities maximizing
the harmonic signal reach up to \r\n4.4\r\n±\r\n0.2\r\n%\r\n (at 17.6 eV). Using
two circularly polarized fields, we observe circular dichroisms ranging up to
\r\n13\r\n±\r\n6\r\n%\r\n (28.3–33.1 eV). Our theoretical analysis confirms that
the observed chiral response originates from subfemtosecond electron dynamics
driven by the magnetic component of the driving laser field. This assignment is
supported by the experimental observation of a strong intensity dependence of
the chiral effects and its agreement with theory. We moreover report and explain
a pronounced variation of the signal strength and dichroism with the driving-field
ellipticities and harmonic orders. Finally, we demonstrate the sensitivity of
the experimental observables to the shape of the electron hole. This technique
for chiral discrimination will yield femtosecond temporal resolution when integrated
in a pump-probe scheme and subfemtosecond resolution on chiral charge migration
in a self-probing scheme."

text: Both classical and recent studies suggest that chromosomal inversion polymorphisms
are important in adaptation and speciation. However, biases in discovery and reporting
of inversions make it difficult to assess their prevalence and biological importance.
Here, we use an approach based on linkage disequilibrium among markers genotyped
for samples collected across a transect between contrasting habitats to detect
chromosomal rearrangements de novo. We report 17 polymorphic rearrangements in
a single locality for the coastal marine snail, Littorina saxatilis. Patterns
of diversity in the field and of recombination in controlled crosses provide strong
evidence that at least the majority of these rearrangements are inversions. Most
show clinal changes in frequency between habitats, suggestive of divergent selection,
but only one appears to be fixed for different arrangements in the two habitats.
Consistent with widespread evidence for balancing selection on inversion polymorphisms,
we argue that a combination of heterosis and divergent selection can explain the
observed patterns and should be considered in other systems spanning environmental
gradients.

text: "We consider the problem of expected cost analysis over nondeterministic probabilistic
programs, which aims at automated methods for analyzing the resource-usage of
such programs. Previous approaches for this problem could only handle nonnegative
bounded costs. However, in many scenarios, such as queuing networks or analysis
of cryptocurrency protocols, both positive and negative costs are necessary and
the costs are unbounded as well.\r\n\r\nIn this work, we present a sound and efficient
approach to obtain polynomial bounds on the expected accumulated cost of nondeterministic
probabilistic programs. Our approach can handle (a) general positive and negative
costs with bounded updates in variables; and (b) nonnegative costs with general
updates to variables. We show that several natural examples which could not be
handled by previous approaches are captured in our framework.\r\n\r\nMoreover,
our approach leads to an efficient polynomial-time algorithm, while no previous
approach for cost analysis of probabilistic programs could guarantee polynomial
runtime. Finally, we show the effectiveness of our approach by presenting experimental
results on a variety of programs, motivated by real-world applications, for which
we efficiently synthesize tight resource-usage bounds."

text: We prove that every congruence distributive variety has directed Jónsson terms,
and every congruence modular variety has directed Gumm terms. The directed terms
we construct witness every case of absorption witnessed by the original Jónsson
or Gumm terms. This result is equivalent to a pair of claims about absorption
for admissible preorders in congruence distributive and congruence modular varieties,
respectively. For finite algebras, these absorption theorems have already seen
significant applications, but until now, it was not clear if the theorems hold
for general algebras as well. Our method also yields a novel proof of a result
by P. Lipparini about the existence of a chain of terms (which we call Pixley
terms) in varieties that are at the same time congruence distributive and k-permutable
for some k.

text: We prove that for every d ≥ 2, deciding if a pure, d-dimensional, simplicial
complex is shellable is NP-hard, hence NP-complete. This resolves a question raised,
e.g., by Danaraj and Klee in 1978. Our reduction also yields that for every d
≥ 2 and k ≥ 0, deciding if a pure, d-dimensional, simplicial complex is k-decomposable
is NP-hard. For d ≥ 3, both problems remain NP-hard when restricted to contractible
pure d-dimensional complexes.

text: In graph theory, as well as in 3-manifold topology, there exist several width-type
parameters to describe how "simple" or "thin" a given graph
or 3-manifold is. These parameters, such as pathwidth or treewidth for graphs,
or the concept of thin position for 3-manifolds, play an important role when studying
algorithmic problems; in particular, there is a variety of problems in computational
3-manifold topology - some of them known to be computationally hard in general
- that become solvable in polynomial time as soon as the dual graph of the input
triangulation has bounded treewidth. In view of these algorithmic results, it
is natural to ask whether every 3-manifold admits a triangulation of bounded treewidth.
We show that this is not the case, i.e., that there exists an infinite family
of closed 3-manifolds not admitting triangulations of bounded pathwidth or treewidth
(the latter implies the former, but we present two separate proofs). We derive
these results from work of Agol and of Scharlemann and Thompson, by exhibiting
explicit connections between the topology of a 3-manifold M on the one hand and
width-type parameters of the dual graphs of triangulations of M on the other hand,
answering a question that had been raised repeatedly by researchers in computational
3-manifold topology. In particular, we show that if a closed, orientable, irreducible,
non-Haken 3-manifold M has a triangulation of treewidth (resp. pathwidth) k then
the Heegaard genus of M is at most 48(k+1) (resp. 4(3k+1)).

text: Nowadays, quantum computation is receiving more and more attention as an alternative
to the classical way of computing. For realizing a quantum computer, different
devices are investigated as potential quantum bits. In this thesis, the focus
is on Ge hut wires, which turned out to be promising candidates for implementing
hole spin quantum bits. The advantages of Ge as a material system are the low
hyperfine interaction for holes and the strong spin orbit coupling, as well as
the compatibility with the highly developed CMOS processes in industry. In addition,
Ge can also be isotopically purified which is expected to boost the spin coherence
times. The strong spin orbit interaction for holes in Ge on the one hand enables
the full electrical control of the quantum bit and on the other hand should allow
short spin manipulation times. Starting with a bare Si wafer, this work covers
the entire process reaching from growth over the fabrication and characterization
of hut wire devices up to the demonstration of hole spin resonance. From experiments
with single quantum dots, a large g-factor anisotropy between the in-plane and
the out-of-plane direction was found. A comparison to a theoretical model unveiled
the heavy-hole character of the lowest energy states. The second part of the thesis
addresses double quantum dot devices, which were realized by adding two gate electrodes
to a hut wire. In such devices, Pauli spin blockade was observed, which can serve
as a read-out mechanism for spin quantum bits. Applying oscillating electric fields
in spin blockade allowed the demonstration of continuous spin rotations and the
extraction of a lower bound for the spin dephasing time. Despite the strong spin
orbit coupling in Ge, the obtained value for the dephasing time is comparable
to what has been recently reported for holes in Si. All in all, the presented
results point out the high potential of Ge hut wires as a platform for long-lived,
fast and fully electrically tunable hole spin quantum bits.

text: 'We describe arrangements of three-dimensional spheres from a geometrical
and topological point of view. Real data (fitting this setup) often consist of
soft spheres which show certain degree of deformation while strongly packing against
each other. In this context, we answer the following questions: If we model a
soft packing of spheres by hard spheres that are allowed to overlap, can we measure
the volume in the overlapped areas? Can we be more specific about the overlap
volume, i.e. quantify how much volume is there covered exactly twice, three times,
or k times? What would be a good optimization criteria that rule the arrangement
of soft spheres while making a good use of the available space? Fixing a particular
criterion, what would be the optimal sphere configuration? The first result of
this thesis are short formulas for the computation of volumes covered by at least
k of the balls. The formulas exploit information contained in the order-k Voronoi
diagrams and its closely related Level-k complex. The used complexes lead to a
natural generalization into poset diagrams, a theoretical formalism that contains
the order-k and degree-k diagrams as special cases. In parallel, we define different
criteria to determine what could be considered an optimal arrangement from a geometrical
point of view. Fixing a criterion, we find optimal soft packing configurations
in 2D and 3D where the ball centers lie on a lattice. As a last step, we use tools
from computational topology on real physical data, to show the potentials of higher-order
diagrams in the description of melting crystals. The results of the experiments
leaves us with an open window to apply the theories developed in this thesis in
real applications.'

text: The most common assumption made in statistical learning theory is the assumption
of the independent and identically distributed (i.i.d.) data. While being very
convenient mathematically, it is often very clearly violated in practice. This
disparity between the machine learning theory and applications underlies a growing
demand in the development of algorithms that learn from dependent data and theory
that can provide generalization guarantees similar to the independent situations.
This thesis is dedicated to two variants of dependencies that can arise in practice.
One is a dependence on the level of samples in a single learning task. Another
dependency type arises in the multi-task setting when the tasks are dependent
on each other even though the data for them can be i.i.d. In both cases we model
the data (samples or tasks) as stochastic processes and introduce new algorithms
for both settings that take into account and exploit the resulting dependencies.
We prove the theoretical guarantees on the performance of the introduced algorithms
under different evaluation criteria and, in addition, we compliment the theoretical
study by the empirical one, where we evaluate some of the algorithms on two real
world datasets to highlight their practical applicability.

text: "A proof system is a protocol between a prover and a verifier over a common
input in which an honest prover convinces the verifier of the validity of true
statements. Motivated by the success of decentralized cryptocurrencies, exemplified
by Bitcoin, the focus of this thesis will be on proof systems which found applications
in some sustainable alternatives to Bitcoin, such as the Spacemint and Chia cryptocurrencies.
In particular, we focus on proofs of space and proofs of sequential work.\r\nProofs
of space (PoSpace) were suggested as more ecological, economical, and egalitarian
alternative to the energy-wasteful proof-of-work mining of Bitcoin. However, the
state-of-the-art constructions of PoSpace are based on sophisticated graph pebbling
lower bounds, and are therefore complex. Moreover, when these PoSpace are used
in cryptocurrencies like Spacemint, miners can only start mining after ensuring
that a commitment to their space is already added in a special transaction to
the blockchain. Proofs of sequential work (PoSW) are proof systems in which a
prover, upon receiving a statement x and a time parameter T, computes a proof
which convinces the verifier that T time units had passed since x was received.
Whereas Spacemint assumes synchrony to retain some interesting Bitcoin dynamics,
Chia requires PoSW with unique proofs, i.e., PoSW in which it is hard to come
up with more than one accepting proof for any true statement. In this thesis we
construct simple and practically-efficient PoSpace and PoSW. When using our PoSpace
in cryptocurrencies, miners can start mining on the fly, like in Bitcoin, and
unlike current constructions of PoSW, which either achieve efficient verification
of sequential work, or faster-than-recomputing verification of correctness of
proofs, but not both at the same time, ours achieve the best of these two worlds."

text: Modern computer vision systems heavily rely on statistical machine learning
models, which typically require large amounts of labeled data to be learned reliably.
Moreover, very recently computer vision research widely adopted techniques for
representation learning, which further increase the demand for labeled data. However,
for many important practical problems there is relatively small amount of labeled
data available, so it is problematic to leverage full potential of the representation
learning methods. One way to overcome this obstacle is to invest substantial resources
into producing large labelled datasets. Unfortunately, this can be prohibitively
expensive in practice. In this thesis we focus on the alternative way of tackling
the aforementioned issue. We concentrate on methods, which make use of weakly-labeled
or even unlabeled data. Specifically, the first half of the thesis is dedicated
to the semantic image segmentation task. We develop a technique, which achieves
competitive segmentation performance and only requires annotations in a form of
global image-level labels instead of dense segmentation masks. Subsequently, we
present a new methodology, which further improves segmentation performance by
leveraging tiny additional feedback from a human annotator. By using our methods
practitioners can greatly reduce the amount of data annotation effort, which is
required to learn modern image segmentation models. In the second half of the
thesis we focus on methods for learning from unlabeled visual data. We study a
family of autoregressive models for modeling structure of natural images and discuss
potential applications of these models. Moreover, we conduct in-depth study of
one of these applications, where we develop the state-of-the-art model for the
probabilistic image colorization task.

text: "A central problem of algebraic topology is to understand the homotopy groups
\ \U0001D70B\U0001D451(\U0001D44B) of a topological space X. For the computational
version of the problem, it is well known that there is no algorithm to decide
whether the fundamental group \U0001D70B1(\U0001D44B) of a given finite simplicial
complex X is trivial. On the other hand, there are several algorithms that, given
a finite simplicial complex X that is simply connected (i.e., with \U0001D70B1(\U0001D44B)
\ trivial), compute the higher homotopy group \U0001D70B\U0001D451(\U0001D44B)
\ for any given \U0001D451≥2 . However, these algorithms come with a caveat:
They compute the isomorphism type of \U0001D70B\U0001D451(\U0001D44B) , \U0001D451≥2
\ as an abstract finitely generated abelian group given by generators and relations,
but they work with very implicit representations of the elements of \U0001D70B\U0001D451(\U0001D44B)
. Converting elements of this abstract group into explicit geometric maps from
the d-dimensional sphere \U0001D446\U0001D451 to X has been one of the main
unsolved problems in the emerging field of computational homotopy theory. Here
we present an algorithm that, given a simply connected space X, computes \U0001D70B\U0001D451(\U0001D44B)
\ and represents its elements as simplicial maps from a suitable triangulation
of the d-sphere \U0001D446\U0001D451 to X. For fixed d, the algorithm runs
in time exponential in size(\U0001D44B) , the number of simplices of X. Moreover,
we prove that this is optimal: For every fixed \U0001D451≥2 , we construct a
family of simply connected spaces X such that for any simplicial map representing
a generator of \U0001D70B\U0001D451(\U0001D44B) , the size of the triangulation
of \U0001D446\U0001D451 on which the map is defined, is exponential in size(\U0001D44B)
."

text: Synchronous programs are easy to specify because the side effects of an operation
are finished by the time the invocation of the operation returns to the caller.
Asynchronous programs, on the other hand, are difficult to specify because there
are side effects due to pending computation scheduled as a result of the invocation
of an operation. They are also difficult to verify because of the large number
of possible interleavings of concurrent computation threads. We present synchronization,
a new proof rule that simplifies the verification of asynchronous programs by
introducing the fiction, for proof purposes, that asynchronous operations complete
synchronously. Synchronization summarizes an asynchronous computation as immediate
atomic effect. Modular verification is enabled via pending asynchronous calls
in atomic summaries, and a complementary proof rule that eliminates pending asynchronous
calls when components and their specifications are composed. We evaluate synchronization
in the context of a multi-layer refinement verification methodology on a collection
of benchmark programs.

text: 'Given a locally finite X ⊆ ℝd and a radius r ≥ 0, the k-fold cover of X and
r consists of all points in ℝd that have k or more points of X within distance
r. We consider two filtrations - one in scale obtained by fixing k and increasing
r, and the other in depth obtained by fixing r and decreasing k - and we compute
the persistence diagrams of both. While standard methods suffice for the filtration
in scale, we need novel geometric and topological concepts for the filtration
in depth. In particular, we introduce a rhomboid tiling in ℝd+1 whose horizontal
integer slices are the order-k Delaunay mosaics of X, and construct a zigzag module
from Delaunay mosaics that is isomorphic to the persistence module of the multi-covers. '

text: Holes confined in quantum dots have gained considerable interest in the past
few years due to their potential as spin qubits. Here we demonstrate two-axis
control of a spin 3/2 qubit in natural Ge. The qubit is formed in a hut wire double
quantum dot device. The Pauli spin blockade principle allowed us to demonstrate
electric dipole spin resonance by applying a radio frequency electric field to
one of the electrodes defining the double quantum dot. Coherent hole spin oscillations
with Rabi frequencies reaching 140 MHz are demonstrated and dephasing times of
130 ns are measured. The reported results emphasize the potential of Ge as a platform
for fast and electrically tunable hole spin qubit devices.

text: The actomyosin cytoskeleton, a key stress-producing unit in epithelial cells,
oscillates spontaneously in a wide variety of systems. Although much of the signal
cascade regulating myosin activity has been characterized, the origin of such
oscillatory behavior is still unclear. Here, we show that basal myosin II oscillation
in Drosophila ovarian epithelium is not controlled by actomyosin cortical tension,
but instead relies on a biochemical oscillator involving ROCK and myosin phosphatase.
Key to this oscillation is a diffusive ROCK flow, linking junctional Rho1 to medial
actomyosin cortex, and dynamically maintained by a self-activation loop reliant
on ROCK kinase activity. In response to the resulting myosin II recruitment, myosin
phosphatase is locally enriched and shuts off ROCK and myosin II signals. Coupling
Drosophila genetics, live imaging, modeling, and optogenetics, we uncover an intrinsic
biochemical oscillator at the core of myosin II regulatory network, shedding light
on the spatio-temporal dynamics of force generation.

text: Lesion verification and quantification is traditionally done via histological
examination of sectioned brains, a time-consuming process that relies heavily
on manual estimation. Such methods are particularly problematic in posterior cortical
regions (e.g. visual cortex), where sectioning leads to significant damage and
distortion of tissue. Even more challenging is the post hoc localization of micro-electrodes,
which relies on the same techniques, suffers from similar drawbacks and requires
even higher precision. Here, we propose a new, simple method for quantitative
lesion characterization and electrode localization that is less labor-intensive
and yields more detailed results than conventional methods. We leverage staining
techniques standard in electron microscopy with the use of commodity micro-CT
imaging. We stain whole rat and zebra finch brains in osmium tetroxide, embed
these in resin and scan entire brains in a micro-CT machine. The scans result
in 3D reconstructions of the brains with section thickness dependent on sample
size (12–15 and 5–6 microns for rat and zebra finch respectively) that can be
segmented manually or automatically. Because the method captures the entire intact
brain volume, comparisons within and across studies are more tractable, and the
extent of lesions and electrodes may be studied with higher accuracy than with
current methods.

text: 'Arabidopsis and human ARM protein interact with telomerase. Deregulated mRNA
levels of DNA repair and ribosomal protein genes in an Arabidopsis arm mutant
suggest non-telomeric ARM function. The human homolog ARMC6 interacts with hTRF2.
Abstract: Telomerase maintains telomeres and has proposed non-telomeric functions.
We previously identified interaction of the C-terminal domain of Arabidopsis telomerase
reverse transcriptase (AtTERT) with an armadillo/β-catenin-like repeat (ARM) containing
protein. Here we explore protein–protein interactions of the ARM protein, AtTERT
domains, POT1a, TRF-like family and SMH family proteins, and the chromatin remodeling
protein CHR19 using bimolecular fluorescence complementation (BiFC), yeast two-hybrid
(Y2H) analysis, and co-immunoprecipitation. The ARM protein interacts with both
the N- and C-terminal domains of AtTERT in different cellular compartments. ARM
interacts with CHR19 and TRF-like I family proteins that also bind AtTERT directly
or through interaction with POT1a. The putative human ARM homolog co-precipitates
telomerase activity and interacts with hTRF2 protein in vitro. Analysis of Arabidopsis
arm mutants shows no obvious changes in telomere length or telomerase activity,
suggesting that ARM is not essential for telomere maintenance. The observed interactions
with telomerase and Myb-like domain proteins (TRF-like family I) may therefore
reflect possible non-telomeric functions. Transcript levels of several DNA repair
and ribosomal genes are affected in arm mutants, and ARM, likely in association
with other proteins, suppressed expression of XRCC3 and RPSAA promoter constructs
in luciferase reporter assays. In conclusion, ARM can participate in non-telomeric
functions of telomerase, and can also perform its own telomerase-independent functions.'

text: We introduce in this paper AMT 2.0 , a tool for qualitative and quantitative
analysis of hybrid continuous and Boolean signals that combine numerical values
and discrete events. The evaluation of the signals is based on rich temporal specifications
expressed in extended Signal Temporal Logic (xSTL), which integrates Timed Regular
Expressions (TRE) within Signal Temporal Logic (STL). The tool features qualitative
monitoring (property satisfaction checking), trace diagnostics for explaining
and justifying property violations and specification-driven measurement of quantitative
features of the signal.

text: Being cared for when sick is a benefit of sociality that can reduce disease
and improve survival of group members. However, individuals providing care risk
contracting infectious diseases themselves. If they contract a low pathogen dose,
they may develop low-level infections that do not cause disease but still affect
host immunity by either decreasing or increasing the host’s vulnerability to subsequent
infections. Caring for contagious individuals can thus significantly alter the
future disease susceptibility of caregivers. Using ants and their fungal pathogens
as a model system, we tested if the altered disease susceptibility of experienced
caregivers, in turn, affects their expression of sanitary care behavior. We found
that low-level infections contracted during sanitary care had protective or neutral
effects on secondary exposure to the same (homologous) pathogen but consistently
caused high mortality on superinfection with a different (heterologous) pathogen.
In response to this risk, the ants selectively adjusted the expression of their
sanitary care. Specifically, the ants performed less grooming and more antimicrobial
disinfection when caring for nestmates contaminated with heterologous pathogens
compared with homologous ones. By modulating the components of sanitary care in
this way the ants acquired less infectious particles of the heterologous pathogens,
resulting in reduced superinfection. The performance of risk-adjusted sanitary
care reveals the remarkable capacity of ants to react to changes in their disease
susceptibility, according to their own infection history and to flexibly adjust
collective care to individual risk.

text: We demonstrate that identical impurities immersed in a two-dimensional many-particle
bath can be viewed as flux-tube-charged-particle composites described by fractional
statistics. In particular, we find that the bath manifests itself as an external
magnetic flux tube with respect to the impurities, and hence the time-reversal
symmetry is broken for the effective Hamiltonian describing the impurities. The
emerging flux tube acts as a statistical gauge field after a certain critical
coupling. This critical coupling corresponds to the intersection point between
the quasiparticle state and the phonon wing, where the angular momentum is transferred
from the impurity to the bath. This amounts to a novel configuration with emerging
anyons. The proposed setup paves the way to realizing anyons using electrons interacting
with superfluid helium or lattice phonons, as well as using atomic impurities
in ultracold gases.

text: The task of a monitor is to watch, at run-time, the execution of a reactive
system, and signal the occurrence of a safety violation in the observed sequence
of events. While finite-state monitors have been studied extensively, in practice,
monitoring software also makes use of unbounded memory. We define a model of automata
equipped with integer-valued registers which can execute only a bounded number
of instructions between consecutive events, and thus can form the theoretical
basis for the study of infinite-state monitors. We classify these register monitors
according to the number k of available registers, and the type of register instructions.
In stark contrast to the theory of computability for register machines, we prove
that for every k 1, monitors with k + 1 counters (with instruction set 〈+1, =〉)
are strictly more expressive than monitors with k counters. We also show that
adder monitors (with instruction set 〈1, +, =〉) are strictly more expressive than
counter monitors, but are complete for monitoring all computable safety -languages
for k = 6. Real-time monitors are further required to signal the occurrence of
a safety violation as soon as it occurs. The expressiveness hierarchy for counter
monitors carries over to real-time monitors. We then show that 2 adders cannot
simulate 3 counters in real-time. Finally, we show that real-time adder monitors
with inequalities are as expressive as real-time Turing machines.

text: Asymmetric auxin distribution is instrumental for the differential growth
that causes organ bending on tropic stimuli and curvatures during plant development.
Local differences in auxin concentrations are achieved mainly by polarized cellular
distribution of PIN auxin transporters, but whether other mechanisms involving
auxin homeostasis are also relevant for the formation of auxin gradients is not
clear. Here we show that auxin methylation is required for asymmetric auxin distribution
across the hypocotyl, particularly during its response to gravity. We found that
loss-of-function mutants in Arabidopsis IAA CARBOXYL METHYLTRANSFERASE1 (IAMT1)
prematurely unfold the apical hook, and that their hypocotyls are impaired in
gravitropic reorientation. This defect is linked to an auxin-dependent increase
in PIN gene expression, leading to an increased polar auxin transport and lack
of asymmetric distribution of PIN3 in the iamt1 mutant. Gravitropic reorientation
in the iamt1 mutant could be restored with either endodermis-specific expression
of IAMT1 or partial inhibition of polar auxin transport, which also results in
normal PIN gene expression levels. We propose that IAA methylation is necessary
in gravity-sensing cells to restrict polar auxin transport within the range of
auxin levels that allow for differential responses.

text: Following an earlier calculation in 3D, we calculate the 2D critical temperature
of a dilute, translation-invariant Bose gas using a variational formulation of
the Bogoliubov approximation introduced by Critchley and Solomon in 1976. This
provides the first analytical calculation of the Kosterlitz-Thouless transition
temperature that includes the constant in the logarithm.
acknowledgement: We thank Robert Seiringer and Daniel Ueltschi for bringing the issue
of the change in critical temperature to our attention. We also thank the Erwin
Schrödinger Institute (all authors) and the Department of Mathematics, University
of Copenhagen (MN) for the hospitality during the period this work was carried out.

text: CLE peptides have been implicated in various developmental processes of plants
and mediate their responses to environmental stimuli. However, the biological
relevance of most CLE genes remains to be functionally characterized. Here, we
report that CLE9, which is expressed in stomata, acts as an essential regulator
in the induction of stomatal closure. Exogenous application of CLE9 peptides or
overexpression of CLE9 effectively led to stomatal closure and enhanced drought
tolerance, whereas CLE9 loss-of-function mutants were sensitivity to drought stress.
CLE9-induced stomatal closure was impaired in abscisic acid (ABA)-deficient mutants,
indicating that ABA is required for CLE9-medaited guard cell signalling. We further
deciphered that two guard cell ABA-signalling components, OST1 and SLAC1, were
responsible for CLE9-induced stomatal closure. MPK3 and MPK6 were activated by
the CLE9 peptide, and CLE9 peptides failed to close stomata in mpk3 and mpk6 mutants.
In addition, CLE9 peptides stimulated the induction of hydrogen peroxide (H2O2)
and nitric oxide (NO) synthesis associated with stomatal closure, which was abolished
in the NADPH oxidase-deficient mutants or nitric reductase mutants, respectively.
Collectively, our results reveal a novel ABA-dependent function of CLE9 in the
regulation of stomatal apertures, thereby suggesting a potential role of CLE9
in the stress acclimatization of plants.

text: Recent lineage tracing studies have revealed that mammary gland homeostasis
relies on unipotent stem cells. However, whether and when lineage restriction
occurs during embryonic mammary development, and which signals orchestrate cell
fate specification, remain unknown. Using a combination of in vivo clonal analysis
with whole mount immunofluorescence and mathematical modelling of clonal dynamics,
we found that embryonic multipotent mammary cells become lineage-restricted surprisingly
early in development, with evidence for unipotency as early as E12.5 and no statistically
discernable bipotency after E15.5. To gain insights into the mechanisms governing
the switch from multipotency to unipotency, we used gain-of-function Notch1 mice
and demonstrated that Notch activation cell autonomously dictates luminal cell
fate specification to both embryonic and basally committed mammary cells. These
functional studies have important implications for understanding the signals underlying
cell plasticity and serve to clarify how reactivation of embryonic programs in
adult cells can lead to cancer.

text: "Additive manufacturing has recently seen drastic improvements in resolution,
making it now possible to fabricate features at scales of hundreds or even dozens
of nanometers, which previously required very expensive lithographic methods.\r\nAs
a result, additive manufacturing now seems poised for optical applications, including
those relevant to computer graphics, such as material design, as well as display
and imaging applications.\r\n \r\nIn this work, we explore the use of additive
manufacturing for generating structural colors, where the structures are designed
using a fabrication-aware optimization process.\r\nThis requires a combination
of full-wave simulation, a feasible parameterization of the design space, and
a tailored optimization procedure.\r\nMany of these components should be re-usable
for the design of other optical structures at this scale.\r\n \r\nWe show initial
results of material samples fabricated based on our designs.\r\nWhile these suffer
from the prototype character of state-of-the-art fabrication hardware, we believe
they clearly demonstrate the potential of additive nanofabrication for structural
colors and other graphics applications."

text: Molding is a popular mass production method, in which the initial expenses
for the mold are offset by the low per-unit production cost. However, the physical
fabrication constraints of the molding technique commonly restrict the shape of
moldable objects. For a complex shape, a decomposition of the object into moldable
parts is a common strategy to address these constraints, with plastic model kits
being a popular and illustrative example. However, conducting such a decomposition
requires considerable expertise, and it depends on the technical aspects of the
fabrication technique, as well as aesthetic considerations. We present an interactive
technique to create such decompositions for two-piece molding, in which each part
of the object is cast between two rigid mold pieces. Given the surface description
of an object, we decompose its thin-shell equivalent into moldable parts by first
performing a coarse decomposition and then utilizing an active contour model for
the boundaries between individual parts. Formulated as an optimization problem,
the movement of the contours is guided by an energy reflecting fabrication constraints
to ensure the moldability of each part. Simultaneously, the user is provided with
editing capabilities to enforce aesthetic guidelines. Our interactive interface
provides control of the contour positions by allowing, for example, the alignment
of part boundaries with object features. Our technique enables a novel workflow,
as it empowers novice users to explore the design space, and it generates fabrication-ready
two-piece molds that can be used either for casting or industrial injection molding
of free-form objects.

text: Direct reciprocity is a mechanism for cooperation among humans. Many of our
daily interactions are repeated. We interact repeatedly with our family, friends,
colleagues, members of the local and even global community. In the theory of repeated
games, it is a tacit assumption that the various games that a person plays simultaneously
have no effect on each other. Here we introduce a general framework that allows
us to analyze “crosstalk” between a player’s concurrent games. In the presence
of crosstalk, the action a person experiences in one game can alter the person’s
decision in another. We find that crosstalk impedes the maintenance of cooperation
and requires stronger levels of forgiveness. The magnitude of the effect depends
on the population structure. In more densely connected social groups, crosstalk
has a stronger effect. A harsh retaliator, such as Tit-for-Tat, is unable to counteract
crosstalk. The crosstalk framework provides a unified interpretation of direct
and upstream reciprocity in the context of repeated games.

text: 'Fast-spiking, parvalbumin-expressing GABAergic interneurons (PV+-BCs) express
a complex machinery of rapid signaling mechanisms, including specialized voltage-gated
ion channels to generate brief action potentials (APs). However, short APs are
associated with overlapping Na+ and K+ fluxes and are therefore energetically
expensive. How the potentially vicious combination of high AP frequency and inefficient
spike generation can be reconciled with limited energy supply is presently unclear.
To address this question, we performed direct recordings from the PV+-BC axon,
the subcellular structure where active conductances for AP initiation and propagation
are located. Surprisingly, the energy required for the AP was, on average, only
∼1.6 times the theoretical minimum. High energy efficiency emerged from the combination
of fast inactivation of Na+ channels and delayed activation of Kv3-type K+ channels,
which minimized ion flux overlap during APs. Thus, the complementary tuning of
axonal Na+ and K+ channel gating optimizes both fast signaling properties and
metabolic efficiency. Hu et al. demonstrate that action potentials in parvalbumin-expressing
GABAergic interneuron axons are energetically efficient, which is highly unexpected
given their brief duration. High energy efficiency emerges from the combination
of fast inactivation of voltage-gated Na+ channels and delayed activation of Kv3
channels in the axon. '

text: Herd immunity, a process in which resistant individuals limit the spread of
a pathogen among susceptible hosts has been extensively studied in eukaryotes.
Even though bacteria have evolved multiple immune systems against their phage
pathogens, herd immunity in bacteria remains unexplored. Here we experimentally
demonstrate that herd immunity arises during phage epidemics in structured and
unstructured Escherichia coli populations consisting of differing frequencies
of susceptible and resistant cells harboring CRISPR immunity. In addition, we
develop a mathematical model that quantifies how herd immunity is affected by
spatial population structure, bacterial growth rate, and phage replication rate.
Using our model we infer a general epidemiological rule describing the relative
speed of an epidemic in partially resistant spatially structured populations.
Our experimental and theoretical findings indicate that herd immunity may be important
in bacterial communities, allowing for stable coexistence of bacteria and their
phages and the maintenance of polymorphism in bacterial immunity.

text: Due to data compression or low resolution, nearby vertices and edges of a
graph drawing may be bundled to a common node or arc. We model such a “compromised”
drawing by a piecewise linear map φ:G → ℝ. We wish to perturb φ by an arbitrarily
small ε>0 into a proper drawing (in which the vertices are distinct points, any
two edges intersect in finitely many points, and no three edges have a common
interior point) that minimizes the number of crossings. An ε-perturbation, for
every ε>0, is given by a piecewise linear map (Formula Presented), where with
||·|| is the uniform norm (i.e., sup norm). We present a polynomial-time solution
for this optimization problem when G is a cycle and the map φ has no spurs (i.e.,
no two adjacent edges are mapped to overlapping arcs). We also show that the problem
becomes NP-complete (i) when G is an arbitrary graph and φ has no spurs, and (ii)
when φ may have spurs and G is a cycle or a union of disjoint paths.

text: Over the past decade, the edge of chaos has proven to be a fruitful starting
point for investigations of shear flows when the laminar base flow is linearly
stable. Numerous computational studies of shear flows demonstrated the existence
of states that separate laminar and turbulent regions of the state space. In addition,
some studies determined invariant solutions that reside on this edge. In this
paper, we study the unstable manifold of one such solution with the aid of continuous
symmetry reduction, which we formulate here for the simultaneous quotiening of
axial and azimuthal symmetries. Upon our investigation of the unstable manifold,
we discover a previously unknown traveling-wave solution on the laminar-turbulent
boundary with a relatively complex structure. By means of low-dimensional projections,
we visualize different dynamical paths that connect these solutions to the turbulence.
Our numerical experiments demonstrate that the laminar-turbulent boundary exhibits
qualitatively different regions whose properties are influenced by the nearby
invariant solutions.

text: Herd immunity, a process in which resistant individuals limit the spread of
a pathogen among susceptible hosts has been extensively studied in eukaryotes.
Even though bacteria have evolved multiple immune systems against their phage
pathogens, herd immunity in bacteria remains unexplored. Here we experimentally
demonstrate that herd immunity arises during phage epidemics in structured and
unstructured Escherichia coli populations consisting of differing frequencies
of susceptible and resistant cells harboring CRISPR immunity. In addition, we
develop a mathematical model that quantifies how herd immunity is affected by
spatial population structure, bacterial growth rate, and phage replication rate.
Using our model we infer a general epidemiological rule describing the relative
speed of an epidemic in partially resistant spatially structured populations.
Our experimental and theoretical findings indicate that herd immunity may be important
in bacterial communities, allowing for stable coexistence of bacteria and their
phages and the maintenance of polymorphism in bacterial immunity.

text: Social insects protect their colonies from infectious disease through collective
defences that result in social immunity. In ants, workers first try to prevent
infection of colony members. Here, we show that if this fails and a pathogen establishes
an infection, ants employ an efficient multicomponent behaviour − "destructive
disinfection" − to prevent further spread of disease through the colony.
Ants specifically target infected pupae during the pathogen's non-contagious incubation
period, relying on chemical 'sickness cues' emitted by pupae. They then remove
the pupal cocoon, perforate its cuticle and administer antimicrobial poison, which
enters the body and prevents pathogen replication from the inside out. Like the
immune system of a body that specifically targets and eliminates infected cells,
this social immunity measure sacrifices infected brood to stop the pathogen completing
its lifecycle, thus protecting the rest of the colony. Hence, the same principles
of disease defence apply at different levels of biological organisation.

text: Pancreas development involves a coordinated process in which an early phase
of cell segregation is followed by a longer phase of lineage restriction, expansion,
and tissue remodeling. By combining clonal tracing and whole-mount reconstruction
with proliferation kinetics and single-cell transcriptional profiling, we define
the functional basis of pancreas morphogenesis. We show that the large-scale organization
of mouse pancreas can be traced to the activity of self-renewing precursors positioned
at the termini of growing ducts, which act collectively to drive serial rounds
of stochastic ductal bifurcation balanced by termination. During this phase of
branching morphogenesis, multipotent precursors become progressively fate-restricted,
giving rise to self-renewing acinar-committed precursors that are conveyed with
growing ducts, as well as ductal progenitors that expand the trailing ducts and
give rise to delaminating endocrine cells. These findings define quantitatively
how the functional behavior and lineage progression of precursor pools determine
the large-scale patterning of pancreatic sub-compartments.

text: Seeds derive from ovules upon fertilization and therefore the total number
of ovules determines the final seed yield, a fundamental trait in crop plants.
Among the factors that co-ordinate the process of ovule formation, the transcription
factors CUP-SHAPED COTYLEDON 1 (CUC1) and CUC2 and the hormone cytokinin (CK)
have a particularly prominent role. Indeed, the absence of both CUC1 and CUC2
causes a severe reduction in ovule number, a phenotype that can be rescued by
CK treatment. In this study, we combined CK quantification with an integrative
genome-wide target identification approach to select Arabidopsis genes regulated
by CUCs that are also involved in CK metabolism. We focused our attention on the
functional characterization of UDP-GLUCOSYL TRANSFERASE 85A3 (UGT85A3) and UGT73C1,
which are up-regulated in the absence of CUC1 and CUC2 and encode enzymes able
to catalyse CK inactivation by O-glucosylation. Our results demonstrate a role
for these UGTs as a link between CUCs and CK homeostasis, and highlight the importance
of CUCs and CKs in the determination of seed yield.

text: Isoprenoid cytokinins play a number of crucial roles in the regulation of
plant growth and development. To study cytokinin receptor properties in plants,
we designed and prepared fluorescent derivatives of 6-[(3-methylbut-2-en-1-yl)amino]purine
(N6-isopentenyladenine, iP) with several fluorescent labels attached to the C2
or N9 atom of the purine moiety via a 2- or 6-carbon linker. The fluorescent labels
included dansyl (DS), fluorescein (FC), 7-nitrobenzofurazan (NBD), rhodamine B
(RhoB), coumarin (Cou), 7-(diethylamino)coumarin (DEAC) and cyanine 5 dye (Cy5).
All prepared compounds were screened for affinity for the Arabidopsis thaliana
cytokinin receptor (CRE1/AHK4). Although the attachment of the fluorescent labels
to iP via the linkers mostly disrupted binding to the receptor, several fluorescent
derivatives interacted well. For this reason, three derivatives, two rhodamine
B and one 4-chloro-7-nitrobenzofurazan labeled iP were tested for their interaction
with CRE1/AHK4 and Zea mays cytokinin receptors in detail. We further showed that
the three derivatives were able to activate transcription of cytokinin response
regulator ARR5 in Arabidopsis seedlings. The activity of fluorescently labeled
cytokinins was compared with corresponding 6-dimethylaminopurine fluorescently
labeled negative controls. Selected rhodamine B C2-labeled compounds 17, 18 and
4-chloro-7-nitrobenzofurazan N9-labeled compound 28 and their respective negative
controls (19, 20 and 29, respectively) were used for in planta staining experiments
in Arabidopsis thaliana cell suspension culture using live cell confocal microscopy.

text: We analyze a disordered central spin model, where a central spin interacts
equally with each spin in a periodic one-dimensional (1D) random-field Heisenberg
chain. If the Heisenberg chain is initially in the many-body localized (MBL) phase,
we find that the coupling to the central spin suffices to delocalize the chain
for a substantial range of coupling strengths. We calculate the phase diagram
of the model and identify the phase boundary between the MBL and ergodic phase.
Within the localized phase, the central spin significantly enhances the rate of
the logarithmic entanglement growth and its saturation value. We attribute the
increase in entanglement entropy to a nonextensive enhancement of magnetization
fluctuations induced by the central spin. Finally, we demonstrate that correlation
functions of the central spin can be utilized to distinguish between MBL and ergodic
phases of the 1D chain. Hence, we propose the use of a central spin as a possible
experimental probe to identify the MBL phase.
