text: 'Behavioral predispositions are innate tendencies of animals to behave in
a given way without the input of learning. They increase survival chances and,
due to environmental and ecological challenges, may vary substantially even between
closely related taxa. These differences are likely to be especially pronounced
in long-lived species like crocodilians. This order is particularly relevant for
comparative cognition due to its phylogenetic proximity to birds. Here we compared
early life behavioral predispositions in two Alligatoridae species. We exposed
American alligator and spectacled caiman hatchlings to three different novel situations:
a novel object, a novel environment that was open and a novel environment with
a shelter. This was then repeated a week later. During exposure to the novel environments,
alligators moved around more and explored a larger range of the arena than the
caimans. When exposed to the novel object, the alligators reduced the mean distance
to the novel object in the second phase, while the caimans further increased it,
indicating diametrically opposite ontogenetic development in behavioral predispositions.
Although all crocodilian hatchlings face comparable challenges, e.g., high predation
pressure, the effectiveness of parental protection might explain the observed
pattern. American alligators are apex predators capable of protecting their offspring
against most dangers, whereas adult spectacled caimans are frequently predated
themselves. Their distancing behavior might be related to increased predator avoidance
and also explain the success of invasive spectacled caimans in the natural habitats
of other crocodilians.'

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

text: “Hydrogen economy” could enable a carbon-neutral sustainable energy chain.
However, issues with safety, storage, and transport of molecular hydrogen impede
its realization. Alcohols as liquid H2 carriers could be enablers, but state-of-the-art
reforming is difficult, requiring high temperatures >200 °C and pressures >25
bar, and the resulting H2 is carbonized beyond tolerance levels for direct use
in fuel cells. Here, we demonstrate ambient temperature and pressure alcohol reforming
in a fuel cell (ARFC) with a simultaneous electrical power output. The alcohol
is oxidized at the alkaline anode, where the resulting CO2 is sequestrated as
carbonate. Carbon-free H2 is liberated at the acidic cathode. The neutralization
energy between the alkaline anode and the acidic cathode drives the process, particularly
the unusually high entropy gain (1.27-fold ΔH). The significantly positive temperature
coefficient of the resulting electromotive force allows us to harvest a large
fraction of the output energy from the surrounding, achieving a thermodynamic
efficiency as high as 2.27. MoS2 as the cathode catalyst allows alcohol reforming
even under open-air conditions, a challenge that state-of-the-art alcohol reforming
failed to overcome. We further show reforming of a wide range of alcohols. The
ARFC offers an unprecedented route toward hydrogen economy as CO2 is simultaneously
captured and pure H2 produced at mild conditions.

text: Cesium lead halides have intrinsically unstable crystal lattices and easily
transform within perovskite and nonperovskite structures. In this work, we explore
the conversion of the perovskite CsPbBr3 into Cs4PbBr6 in the presence of PbS
at 450 °C to produce doped nanocrystal-based composites with embedded Cs4PbBr6
nanoprecipitates. We show that PbBr2 is extracted from CsPbBr3 and diffuses into
the PbS lattice with a consequent increase in the concentration of free charge
carriers. This new doping strategy enables the adjustment of the density of charge
carriers between 1019 and 1020 cm–3, and it may serve as a general strategy for
doping other nanocrystal-based semiconductors.

text: 'We present DILS, a deployable statistical analysis platform for conducting
demographic inferences with linked selection from population genomic data using
an Approximate Bayesian Computation framework. DILS takes as input single‐population
or two‐population data sets (multilocus fasta sequences) and performs three types
of analyses in a hierarchical manner, identifying: (a) the best demographic model
to study the importance of gene flow and population size change on the genetic
patterns of polymorphism and divergence, (b) the best genomic model to determine
whether the effective size Ne and migration rate N, m are heterogeneously distributed
along the genome (implying linked selection) and (c) loci in genomic regions most
associated with barriers to gene flow. Also available via a Web interface, an
objective of DILS is to facilitate collaborative research in speciation genomics.
Here, we show the performance and limitations of DILS by using simulations and
finally apply the method to published data on a divergence continuum composed
by 28 pairs of Mytilus mussel populations/species.'

text: "We show that the energy gap for the BCS gap equation is\r\nΞ=μ(8e−2+o(1))exp(π2μ−−√a)\r\nin
the low density limit μ→0. Together with the similar result for the critical temperature
by Hainzl and Seiringer (Lett Math Phys 84: 99–107, 2008), this shows that, in
the low density limit, the ratio of the energy gap and critical temperature is
a universal constant independent of the interaction potential V. The results hold
for a class of potentials with negative scattering length a and no bound states."

text: While several tools have been developed to study the ground state of many-body
quantum spin systems, the limitations of existing techniques call for the exploration
of new approaches. In this manuscript we develop an alternative analytical and
numerical framework for many-body quantum spin ground states, based on the disentanglement
formalism. In this approach, observables are exactly expressed as Gaussian-weighted
functional integrals over scalar fields. We identify the leading contribution
to these integrals, given by the saddle point of a suitable effective action.
Analytically, we develop a field-theoretical expansion of the functional integrals,
performed by means of appropriate Feynman rules. The expansion can be truncated
to a desired order to obtain analytical approximations to observables. Numerically,
we show that the disentanglement approach can be used to compute ground state
expectation values from classical stochastic processes. While the associated fluctuations
grow exponentially with imaginary time and the system size, this growth can be
mitigated by means of an importance sampling scheme based on knowledge of the
saddle point configuration. We illustrate the advantages and limitations of our
methods by considering the quantum Ising model in 1, 2 and 3 spatial dimensions.
Our analytical and numerical approaches are applicable to a broad class of systems,
bridging concepts from quantum lattice models, continuum field theory, and classical
stochastic processes.

text: Interspecific crossing experiments have shown that sex chromosomes play a
major role in reproductive isolation between many pairs of species. However, their
ability to act as reproductive barriers, which hamper interspecific genetic exchange,
has rarely been evaluated quantitatively compared to Autosomes. This genome-wide
limitation of gene flow is essential for understanding the complete separation
of species, and thus speciation. Here, we develop a mainland-island model of secondary
contact between hybridizing species of an XY (or ZW) sexual system. We obtain
theoretical predictions for the frequency of introgressed alleles, and the strength
of the barrier to neutral gene flow for the two types of chromosomes carrying
multiple interspecific barrier loci. Theoretical predictions are obtained for
scenarios where introgressed alleles are rare. We show that the same analytical
expressions apply for sex chromosomes and autosomes, but with different sex-averaged
effective parameters. The specific features of sex chromosomes (hemizygosity and
absence of recombination in the heterogametic sex) lead to reduced levels of introgression
on the X (or Z) compared to autosomes. This effect can be enhanced by certain
types of sex-biased forces, but it remains overall small (except when alleles
causing incompatibilities are recessive). We discuss these predictions in the
light of empirical data comprising model-based tests of introgression and cline
surveys in various biological systems.

text: We show that Hilbert schemes of points on supersingular Enriques surface in
characteristic 2, Hilbn(X), for n ≥ 2 are simply connected, symplectic varieties
but are not irreducible symplectic as the hodge number h2,0 > 1, even though a
supersingular Enriques surface is an irreducible symplectic variety. These are
the classes of varieties which appear only in characteristic 2 and they show that
the hodge number formula for G¨ottsche-Soergel does not hold over haracteristic
2. It also gives examples of varieties with trivial canonical class which are
neither irreducible symplectic nor Calabi-Yau, thereby showing that there are
strictly more classes of simply connected varieties with trivial canonical class
in characteristic 2 than over C as given by Beauville-Bogolomov decomposition
theorem.

text: Genomic imprinting is an epigenetic mechanism that results in parental allele-specific
expression of ~1% of all genes in mouse and human. Imprinted genes are key developmental
regulators and play pivotal roles in many biological processes such as nutrient
transfer from the mother to offspring and neuronal development. Imprinted genes
are also involved in human disease, including neurodevelopmental disorders, and
often occur in clusters that are regulated by a common imprint control region
(ICR). In extra-embryonic tissues ICRs can act over large distances, with the
largest surrounding Igf2r spanning over 10 million base-pairs. Besides classical
imprinted expression that shows near exclusive maternal or paternal expression,
widespread biased imprinted expression has been identified mainly in brain. In
this review we discuss recent developments mapping cell type specific imprinted
expression in extra-embryonic tissues and neocortex in the mouse. We highlight
the advantages of using an inducible uniparental chromosome disomy (UPD) system
to generate cells carrying either two maternal or two paternal copies of a specific
chromosome to analyze the functional consequences of genomic imprinting. Mosaic
Analysis with Double Markers (MADM) allows fluorescent labeling and concomitant
induction of UPD sparsely in specific cell types, and thus to over-express or
suppress all imprinted genes on that chromosome. To illustrate the utility of
this technique, we explain how MADM-induced UPD revealed new insights about the
function of the well-studied Cdkn1c imprinted gene, and how MADM-induced UPDs
led to identification of highly cell type specific phenotypes related to perturbed
imprinted expression in the mouse neocortex. Finally, we give an outlook on how
MADM could be used to probe cell type specific imprinted expression in other tissues
in mouse, particularly in extra-embryonic tissues.

text: Transposable elements exist widely throughout plant genomes and play important
roles in plant evolution. Auxin is an important regulator that is traditionally
associated with root development and drought stress adaptation. The DEEPER ROOTING
1 (DRO1) gene is a key component of rice drought avoidance. Here, we identified
a transposon that acts as an autonomous auxin‐responsive promoter and its presence
at specific genome positions conveys physiological adaptations related to drought
avoidance. Rice varieties with high and auxin‐mediated transcription of DRO1 in
the root tip show deeper and longer root phenotypes and are thus better adapted
to drought. The INDITTO2 transposon contains an auxin response element and displays
auxin‐responsive promoter activity; it is thus able to convey auxin regulation
of transcription to genes in its proximity. In the rice Acuce, which displays
DRO1‐mediated drought adaptation, the INDITTO2 transposon was found to be inserted
at the promoter region of the DRO1 locus. Transgenesis‐based insertion of the
INDITTO2 transposon into the DRO1 promoter of the non‐adapted rice variety Nipponbare
was sufficient to promote its drought avoidance. Our data identify an example
of how transposons can act as promoters and convey hormonal regulation to nearby
loci, improving plant fitness in response to different abiotic stresses.

text: Formal design of embedded and cyber-physical systems relies on mathematical
modeling. In this paper, we consider the model class of hybrid automata whose
dynamics are defined by affine differential equations. Given a set of time-series
data, we present an algorithmic approach to synthesize a hybrid automaton exhibiting
behavior that is close to the data, up to a specified precision, and changes in
synchrony with the data. A fundamental problem in our synthesis algorithm is to
check membership of a time series in a hybrid automaton. Our solution integrates
reachability and optimization techniques for affine dynamical systems to obtain
both a sufficient and a necessary condition for membership, combined in a refinement
framework. The algorithm processes one time series at a time and hence can be
interrupted, provide an intermediate result, and be resumed. We report experimental
results demonstrating the applicability of our synthesis approach.

text: Cryo-EM grid preparation is an important bottleneck in protein structure determination,
especially for membrane proteins, typically requiring screening of a large number
of conditions. We systematically investigated the effects of buffer components,
blotting conditions and grid types on the outcome of grid preparation of five
different membrane protein samples. Aggregation was the most common type of problem
which was addressed by changing detergents, salt concentration or reconstitution
of proteins into nanodiscs or amphipols. We show that the optimal concentration
of detergent is between 0.05 and 0.4% and that the presence of a low concentration
of detergent with a high critical micellar concentration protects the proteins
from denaturation at the air-water interface. Furthermore, we discuss the strategies
for achieving an adequate ice thickness, particle coverage and orientation distribution
on free ice and on support films. Our findings provide a clear roadmap for comprehensive
screening of conditions for cryo-EM grid preparation of membrane proteins.

text: 'The precise engineering of thermoelectric materials using nanocrystals as
their building blocks has proven to be an excellent strategy to increase energy
conversion efficiency. Here we present a synthetic route to produce Sb-doped PbS
colloidal nanoparticles. These nanoparticles are then consolidated into nanocrystalline
PbS:Sb using spark plasma sintering. We demonstrate that the introduction of Sb
significantly influences the size, geometry, crystal lattice and especially the
carrier concentration of PbS. The increase of charge carrier concentration achieved
with the introduction of Sb translates into an increase of the electrical and
thermal conductivities and a decrease of the Seebeck coefficient. Overall, PbS:Sb
nanomaterial were characterized by two-fold higher thermoelectric figures of merit
than undoped PbS. '

text: "In this paper we experimentally study the transitional range of Reynolds
numbers in\r\nplane Couette–Poiseuille flow, focusing our attention on the localized
turbulent structures\r\ntriggered by a strong impulsive jet and the large-scale
flow generated around these\r\nstructures. We present a detailed investigation
of the large-scale flow and show how\r\nits amplitude depends on Reynolds number
and amplitude perturbation. In addition,\r\nwe characterize the initial dynamics
of the localized turbulent spot, which includes the\r\ncoupling between the small
and large scales, as well as the dependence of the advection\r\nspeed on the large-scale
flow generated around the spot. Finally, we provide the first\r\nexperimental
measurements of the large-scale flow around an oblique turbulent band."

text: "Modern neural networks can easily fit their training set perfectly. Surprisingly,
despite being “overfit” in this way, they tend to generalize well to future data,
thereby defying the classic bias–variance trade-off of machine learning theory.
Of the many possible explanations, a prevalent one is that training by stochastic
gradient descent (SGD) imposes an implicit bias that leads it to learn simple
functions, and these simple functions generalize well. However, the specifics
of this implicit bias are not well understood.\r\nIn this work, we explore the
smoothness conjecture which states that SGD is implicitly biased towards learning
functions that are smooth. We propose several measures to formalize the intuitive
notion of smoothness, and we conduct experiments to determine whether SGD indeed
implicitly optimizes for these measures. Our findings rule out the possibility
that smoothness measures based on first-order derivatives are being implicitly
enforced. They are supportive, though, of the smoothness conjecture for measures
based on second-order derivatives."

text: Plant fitness is largely dependent on the root, the underground organ, which,
besides its anchoring function, supplies the plant body with water and all nutrients
necessary for growth and development. To exploit the soil effectively, roots must
constantly integrate environmental signals and react through adjustment of growth
and development. Important components of the root management strategy involve
a rapid modulation of the root growth kinetics and growth direction, as well as
an increase of the root system radius through formation of lateral roots (LRs).
At the molecular level, such a fascinating growth and developmental flexibility
of root organ requires regulatory networks that guarantee stability of the developmental
program but also allows integration of various environmental inputs. The plant
hormone auxin is one of the principal endogenous regulators of root system architecture
by controlling primary root growth and formation of LR. In this review, we discuss
recent progress in understanding molecular networks where auxin is one of the
main players shaping the root system and acting as mediator between endogenous
cues and environmental factors.

text: We re-examine attempts to study the many-body localization transition using
measures that are physically natural on the ergodic/quantum chaotic regime of
the phase diagram. Using simple scaling arguments and an analysis of various models
for which rigorous results are available, we find that these measures can be particularly
adversely affected by the strong finite-size effects observed in nearly all numerical
studies of many-body localization. This severely impacts their utility in probing
the transition and the localized phase. In light of this analysis, we discuss
a recent study (Šuntajs et al., 2020) of the behaviour of the Thouless energy
and level repulsion in disordered spin chains, and its implications for the question
of whether MBL is a true phase of matter.

text: "The Landau–Pekar equations describe the dynamics of a strongly coupled polaron.\r\nHere,
we provide a class of initial data for which the associated effective Hamiltonian\r\nhas
a uniform spectral gap for all times. For such initial data, this allows us to
extend the\r\nresults on the adiabatic theorem for the Landau–Pekar equations
and their derivation\r\nfrom the Fröhlich model obtained in previous works to
larger times."
