text: 'We present solutions to several problems originating from geometry and discrete
mathematics: existence of equipartitions, maps without Tverberg multiple points,
and inscribing quadrilaterals. Equivariant obstruction theory is the natural topological
approach to these type of questions. However, for the specific problems we consider
it had yielded only partial or no results. We get our results by complementing
equivariant obstruction theory with other techniques from topology and geometry.'

text: In mammalian genomes, a subset of genes is regulated by genomic imprinting,
resulting in silencing of one parental allele. Imprinting is essential for cerebral
cortex development, but prevalence and functional impact in individual cells is
unclear. Here, we determined allelic expression in cortical cell types and established
a quantitative platform to interrogate imprinting in single cells. We created
cells with uniparental chromosome disomy (UPD) containing two copies of either
the maternal or the paternal chromosome; hence, imprinted genes will be 2-fold
overexpressed or not expressed. By genetic labeling of UPD, we determined cellular
phenotypes and transcriptional responses to deregulated imprinted gene expression
at unprecedented single-cell resolution. We discovered an unexpected degree of
cell-type specificity and a novel function of imprinting in the regulation of
cortical astrocyte survival. More generally, our results suggest functional relevance
of imprinted gene expression in glial astrocyte lineage and thus for generating
cortical cell-type diversity.

text: Fejes Tóth [3] studied approximations of smooth surfaces in three-space by
piecewise flat triangular meshes with a given number of vertices on the surface
that are optimal with respect to Hausdorff distance. He proves that this Hausdorff
distance decreases inversely proportional with the number of vertices of the approximating
mesh if the surface is convex. He also claims that this Hausdorff distance is
inversely proportional to the square of the number of vertices for a specific
non-convex surface, namely a one-sheeted hyperboloid of revolution bounded by
two congruent circles. We refute this claim, and show that the asymptotic behavior
of the Hausdorff distance is linear, that is the same as for convex surfaces.

text: The evolution of strong reproductive isolation (RI) is fundamental to the
origins and maintenance of biological diversity, especially in situations where
geographical distributions of taxa broadly overlap. But what is the history behind
strong barriers currently acting in sympatry? Using whole-genome sequencing and
single nucleotide polymorphism genotyping, we inferred (i) the evolutionary relationships,
(ii) the strength of RI, and (iii) the demographic history of divergence between
two broadly sympatric taxa of intertidal snail. Despite being cryptic, based on
external morphology, Littorina arcana and Littorina saxatilis differ in their
mode of female reproduction (egg-laying versus brooding), which may generate a
strong post-zygotic barrier. We show that egg-laying and brooding snails are closely
related, but genetically distinct. Genotyping of 3092 snails from three locations
failed to recover any recent hybrid or backcrossed individuals, confirming that
RI is strong. There was, however, evidence for a very low level of asymmetrical
introgression, suggesting that isolation remains incomplete. The presence of strong,
asymmetrical RI was further supported by demographic analysis of these populations.
Although the taxa are currently broadly sympatric, demographic modelling suggests
that they initially diverged during a short period of geographical separation
involving very low gene flow. Our study suggests that some geographical separation
may kick-start the evolution of strong RI, facilitating subsequent coexistence
of taxa in sympatry. The strength of RI needed to achieve sympatry and the subsequent
effect of sympatry on RI remain open questions.

text: Speciation, that is, the evolution of reproductive barriers eventually leading
to complete isolation, is a crucial process generating biodiversity. Recent work
has contributed much to our understanding of how reproductive barriers begin to
evolve, and how they are maintained in the face of gene flow. However, little
is known about the transition from partial to strong reproductive isolation (RI)
and the completion of speciation. We argue that the evolution of strong RI is
likely to involve different processes, or new interactions among processes, compared
with the evolution of the first reproductive barriers. Transition to strong RI
may be brought about by changing external conditions, for example, following secondary
contact. However, the increasing levels of RI themselves create opportunities
for new barriers to evolve and, and interaction or coupling among barriers. These
changing processes may depend on genomic architecture and leave detectable signals
in the genome. We outline outstanding questions and suggest more theoretical and
empirical work, considering both patterns and processes associated with strong
RI, is needed to understand how speciation is completed.

text: Many recent studies have addressed the mechanisms operating during the early
stages of speciation, but surprisingly few studies have tested theoretical predictions
on the evolution of strong reproductive isolation (RI). To help address this gap,
we first undertook a quantitative review of the hybrid zone literature for flowering
plants in relation to reproductive barriers. Then, using Populus as an exemplary
model group, we analysed genome-wide variation for phylogenetic tree topologies
in both early- and late-stage speciation taxa to determine how these patterns
may be related to the genomic architecture of RI. Our plant literature survey
revealed variation in barrier complexity and an association between barrier number
and introgressive gene flow. Focusing on Populus, our genome-wide analysis of
tree topologies in speciating poplar taxa points to unusually complex genomic
architectures of RI, consistent with earlier genome-wide association studies.
These architectures appear to facilitate the ‘escape’ of introgressed genome segments
from polygenic barriers even with strong RI, thus affecting their relationships
with recombination rates. Placed within the context of the broader literature,
our data illustrate how phylogenomic approaches hold great promise for addressing
the evolution and temporary breakdown of RI during late stages of speciation.

text: "Alignment of OCS, CS2, and I2 molecules embedded in helium nanodroplets is
measured as a function\r\nof time following rotational excitation by a nonresonant,
comparatively weak ps laser pulse. The distinct\r\npeaks in the power spectra,
obtained by Fourier analysis, are used to determine the rotational, B, and\r\ncentrifugal
distortion, D, constants. For OCS, B and D match the values known from IR spectroscopy.
For\r\nCS2 and I2, they are the first experimental results reported. The alignment
dynamics calculated from the\r\ngas-phase rotational Schrödinger equation, using
the experimental in-droplet B and D values, agree in\r\ndetail with the measurement
for all three molecules. The rotational spectroscopy technique for molecules in\r\nhelium
droplets introduced here should apply to a range of molecules and complexes."

text: Understanding how the activity of membrane receptors and cellular signaling
pathways shapes cell behavior is of fundamental interest in basic and applied
research. Reengineering receptors to react to light instead of their cognate ligands
allows for generating defined signaling inputs with high spatial and temporal
precision and facilitates the dissection of complex signaling networks. Here,
we describe fundamental considerations in the design of light-regulated receptor
tyrosine kinases (Opto-RTKs) and appropriate control experiments. We also introduce
methods for transient receptor expression in HEK293 cells, quantitative assessment
of signaling activity in reporter gene assays, semiquantitative assessment of
(in)activation time courses through Western blot (WB) analysis, and easy to implement
light stimulation hardware.

text: "Numerous methods have been proposed for probabilistic generative modelling
of\r\n3D objects. However, none of these is able to produce textured objects,
which\r\nrenders them of limited use for practical tasks. In this work, we present
the\r\nfirst generative model of textured 3D meshes. Training such a model would\r\ntraditionally
require a large dataset of textured meshes, but unfortunately,\r\nexisting datasets
of meshes lack detailed textures. We instead propose a new\r\ntraining methodology
that allows learning from collections of 2D images without\r\nany 3D information.
To do so, we train our model to explain a distribution of\r\nimages by modelling
each image as a 3D foreground object placed in front of a\r\n2D background. Thus,
it learns to generate meshes that when rendered, produce\r\nimages similar to
those in its training set.\r\n A well-known problem when generating meshes with
deep networks is the\r\nemergence of self-intersections, which are problematic
for many use-cases. As a\r\nsecond contribution we therefore introduce a new generation
process for 3D\r\nmeshes that guarantees no self-intersections arise, based on
the physical\r\nintuition that faces should push one another out of the way as
they move.\r\n We conduct extensive experiments on our approach, reporting quantitative
and\r\nqualitative results on both synthetic data and natural images. These show
our\r\nmethod successfully learns to generate plausible and diverse textured 3D\r\nsamples
for five challenging object classes."

text: "A natural approach to generative modeling of videos is to represent them
as a composition of moving objects. Recent works model a set of 2D sprites over
a slowly-varying background, but without considering the underlying 3D scene that\r\ngives
rise to them. We instead propose to model a video as the view seen while moving
through a scene with multiple 3D objects and a 3D background. Our model is trained
from monocular videos without any supervision, yet learns to\r\ngenerate coherent
3D scenes containing several moving objects. We conduct detailed experiments on
two datasets, going beyond the visual complexity supported by state-of-the-art
generative approaches. We evaluate our method on\r\ndepth-prediction and 3D object
detection---tasks which cannot be addressed by those earlier works---and show
it out-performs them even on 2D instance segmentation and tracking."

text: Direct ethanol fuel cells (DEFCs) show a huge potential to power future electric
vehicles and portable electronics, but their deployment is currently limited by
the unavailability of proper electrocatalysis for the ethanol oxidation reaction
(EOR). In this work, we engineer a new electrocatalyst by incorporating phosphorous
into a palladium-tin alloy and demonstrate a significant performance improvement
toward EOR. We first detail a synthetic method to produce Pd2Sn:P nanocrystals
that incorporate 35% of phosphorus. These nanoparticles are supported on carbon
black and tested for EOR. Pd2Sn:P/C catalysts exhibit mass current densities up
to 5.03 A mgPd−1, well above those of Pd2Sn/C, PdP2/C and Pd/C reference catalysts.
Furthermore, a twofold lower Tafel slope and a much longer durability are revealed
for the Pd2Sn:P/C catalyst compared with Pd/C. The performance improvement is
rationalized with the aid of density functional theory (DFT) calculations considering
different phosphorous chemical environments. Depending on its oxidation state,
surface phosphorus introduces sites with low energy OH− adsorption and/or strongly
influences the electronic structure of palladium and tin to facilitate the oxidation
of the acetyl to acetic acid, which is considered the EOR rate limiting step.
DFT calculations also points out that the durability improvement of Pd2Sn:P/C
catalyst is associated to the promotion of OH adsorption that accelerates the
oxidation of intermediate poisoning COads, reactivating the catalyst surface.

text: "There has been a significant amount of research on hardware and software
support for efficient concurrent data structures; yet, the question of how to
build correct, simple, and scalable data structures has not yet been definitively
settled. In this paper, we revisit this question from a minimalist perspective,
and ask: what is the smallest amount of synchronization required for correct and
efficient concurrent search data structures, and how could this minimal synchronization
support be provided in hardware?\r\n\r\nTo address these questions, we introduce
memory tagging, a simple hardware mechanism which enables the programmer to \"tag\"
a dynamic set of memory locations, at cache-line granularity, and later validate
whether the memory has been concurrently modified, with the possibility of updating
one of the underlying locations atomically if validation succeeds. We provide
several examples showing that this mechanism can enable fast and arguably simple
concurrent data structure designs, such as lists, binary search trees, balanced
search trees, range queries, and Software Transactional Memory (STM) implementations.
We provide an implementation of memory tags in the Graphite multi-core simulator,
showing that the mechanism can be implemented entirely at the level of L1 cache,
and that it can enable non-trivial speedups versus existing implementations of
the above data structures."

text: 'Multiple-environment Markov decision processes (MEMDPs) are MDPs equipped
with not one, but multiple probabilistic transition functions, which represent
the various possible unknown environments. While the previous research on MEMDPs
focused on theoretical properties for long-run average payoff, we study them with
discounted-sum payoff and focus on their practical advantages and applications.
MEMDPs can be viewed as a special case of Partially observable and Mixed observability
MDPs: the state of the system is perfectly observable, but not the environment.
We show that the specific structure of MEMDPs allows for more efficient algorithmic
analysis, in particular for faster belief updates. We demonstrate the applicability
of MEMDPs in several domains. In particular, we formalize the sequential decision-making
approach to contextual recommendation systems as MEMDPs and substantially improve
over the previous MDP approach.'

text: 'Fixed-point arithmetic is a popular alternative to floating-point arithmetic
on embedded systems. Existing work on the verification of fixed-point programs
relies on custom formalizations of fixed-point arithmetic, which makes it hard
to compare the described techniques or reuse the implementations. In this paper,
we address this issue by proposing and formalizing an SMT theory of fixed-point
arithmetic. We present an intuitive yet comprehensive syntax of the fixed-point
theory, and provide formal semantics for it based on rational arithmetic. We also
describe two decision procedures for this theory: one based on the theory of bit-vectors
and the other on the theory of reals. We implement the two decision procedures,
and evaluate our implementations using existing mature SMT solvers on a benchmark
suite we created. Finally, we perform a case study of using the theory we propose
to verify properties of quantized neural networks.'

text: This paper presents a foundation for refining concurrent programs with structured
control flow. The verification problem is decomposed into subproblems that aid
interactive program development, proof reuse, and automation. The formalization
in this paper is the basis of a new design and implementation of the Civl verifier.

text: We investigate a mechanism to transiently stabilize topological phenomena
in long-lived quasi-steady states of isolated quantum many-body systems driven
at low frequencies. We obtain an analytical bound for the lifetime of the quasi-steady
states which is exponentially large in the inverse driving frequency. Within this
lifetime, the quasi-steady state is characterized by maximum entropy subject to
the constraint of fixed number of particles in the system's Floquet-Bloch bands.
In such a state, all the non-universal properties of these bands are washed out,
hence only the topological properties persist.

text: Using inelastic cotunneling spectroscopy we observe a zero field splitting
within the spin triplet manifold of Ge hut wire quantum dots. The states with
spin ±1 in the confinement direction are energetically favored by up to 55 μeV
compared to the spin 0 triplet state because of the strong spin–orbit coupling.
The reported effect should be observable in a broad class of strongly confined
hole quantum-dot systems and might need to be considered when operating hole spin
qubits.

text: Understanding to what extent stem cell potential is a cell-intrinsic property
or an emergent behavior coming from global tissue dynamics and geometry is a key
outstanding question of systems and stem cell biology. Here, we propose a theory
of stem cell dynamics as a stochastic competition for access to a spatially localized
niche, giving rise to a stochastic conveyor-belt model. Cell divisions produce
a steady cellular stream which advects cells away from the niche, while random
rearrangements enable cells away from the niche to be favorably repositioned.
Importantly, even when assuming that all cells in a tissue are molecularly equivalent,
we predict a common (“universal”) functional dependence of the long-term clonal
survival probability on distance from the niche, as well as the emergence of a
well-defined number of functional stem cells, dependent only on the rate of random
movements vs. mitosis-driven advection. We test the predictions of this theory
on datasets of pubertal mammary gland tips and embryonic kidney tips, as well
as homeostatic intestinal crypts. Importantly, we find good agreement for the
predicted functional dependency of the competition as a function of position,
and thus functional stem cell number in each organ. This argues for a key role
of positional fluctuations in dictating stem cell number and dynamics, and we
discuss the applicability of this theory to other settings.
