text: Pancreatic islets play an essential role in regulating blood glucose level.
Although the molecular pathways underlying islet cell differentiation are beginning
to be resolved, the cellular basis of islet morphogenesis and fate allocation
remain unclear. By combining unbiased and targeted lineage tracing, we address
the events leading to islet formation in the mouse. From the statistical analysis
of clones induced at multiple embryonic timepoints, here we show that, during
the secondary transition, islet formation involves the aggregation of multiple
equipotent endocrine progenitors that transition from a phase of stochastic amplification
by cell division into a phase of sublineage restriction and limited islet fission.
Together, these results explain quantitatively the heterogeneous size distribution
and degree of polyclonality of maturing islets, as well as dispersion of progenitors
within and between islets. Further, our results show that, during the secondary
transition, α- and β-cells are generated in a contemporary manner. Together, these
findings provide insight into the cellular basis of islet development.

text: The α–z Rényi relative entropies are a two-parameter family of Rényi relative
entropies that are quantum generalizations of the classical α-Rényi relative entropies.
In the work [Adv. Math. 365, 107053 (2020)], we decided the full range of (α,
z) for which the data processing inequality (DPI) is valid. In this paper, we
give algebraic conditions for the equality in DPI. For the full range of parameters
(α, z), we give necessary conditions and sufficient conditions. For most parameters,
we give equivalent conditions. This generalizes and strengthens the results of
Leditzky et al. [Lett. Math. Phys. 107, 61–80 (2017)].

text: 'We study relations between evidence theory and S-approximation spaces. Both
theories have their roots in the analysis of Dempsterchr(''39'')s multivalued
mappings and lower and upper probabilities, and have close relations to rough
sets. We show that an S-approximation space, satisfying a monotonicity condition,
can induce a natural belief structure which is a fundamental block in evidence
theory. We also demonstrate that one can induce a natural belief structure on
one set, given a belief structure on another set, if the two sets are related
by a partial monotone S-approximation space. '

text: Cell fate transitions are key to development and homeostasis. It is thus essential
to understand the cellular mechanisms controlling fate transitions. Cell division
has been implicated in fate decisions in many stem cell types, including neuronal
and epithelial progenitors. In other stem cells, such as embryonic stem (ES) cells,
the role of division remains unclear. Here, we show that exit from naive pluripotency
in mouse ES cells generally occurs after a division. We further show that exit
timing is strongly correlated between sister cells, which remain connected by
cytoplasmic bridges long after division, and that bridge abscission progressively
accelerates as cells exit naive pluripotency. Finally, interfering with abscission
impairs naive pluripotency exit, and artificially inducing abscission accelerates
it. Altogether, our data indicate that a switch in the division machinery leading
to faster abscission regulates pluripotency exit. Our study identifies abscission
as a key cellular process coupling cell division to fate transitions.

text: 'Extrasynaptic actions of glutamate are limited by high-affinity transporters
expressed by perisynaptic astroglial processes (PAPs): this helps maintain point-to-point
transmission in excitatory circuits. Memory formation in the brain is associated
with synaptic remodeling, but how this affects PAPs and therefore extrasynaptic
glutamate actions is poorly understood. Here, we used advanced imaging methods,
in situ and in vivo, to find that a classical synaptic memory mechanism, long-term
potentiation (LTP), triggers withdrawal of PAPs from potentiated synapses. Optical
glutamate sensors combined with patch-clamp and 3D molecular localization reveal
that LTP induction thus prompts spatial retreat of astroglial glutamate transporters,
boosting glutamate spillover and NMDA-receptor-mediated inter-synaptic cross-talk.
The LTP-triggered PAP withdrawal involves NKCC1 transporters and the actin-controlling
protein cofilin but does not depend on major Ca2+-dependent cascades in astrocytes.
We have therefore uncovered a mechanism by which a memory trace at one synapse
could alter signal handling by multiple neighboring connections.'

text: A central goal of artificial intelligence in high-stakes decision-making applications
is to design a single algorithm that simultaneously expresses generalizability
by learning coherent representations of their world and interpretable explanations
of its dynamics. Here, we combine brain-inspired neural computation principles
and scalable deep learning architectures to design compact neural controllers
for task-specific compartments of a full-stack autonomous vehicle control system.
We discover that a single algorithm with 19 control neurons, connecting 32 encapsulated
input features to outputs by 253 synapses, learns to map high-dimensional inputs
into steering commands. This system shows superior generalizability, interpretability
and robustness compared with orders-of-magnitude larger black-box learning systems.
The obtained neural agents enable high-fidelity autonomy for task-specific parts
of a complex autonomous system.

text: Animal development entails the organization of specific cell types in space
and time, and spatial patterns must form in a robust manner. In the zebrafish
spinal cord, neural progenitors form stereotypic patterns despite noisy morphogen
signaling and large-scale cellular rearrangements during morphogenesis and growth.
By directly measuring adhesion forces and preferences for three types of endogenous
neural progenitors, we provide evidence for the differential adhesion model in
which differences in intercellular adhesion mediate cell sorting. Cell type–specific
combinatorial expression of different classes of cadherins (N-cadherin, cadherin
11, and protocadherin 19) results in homotypic preference ex vivo and patterning
robustness in vivo. Furthermore, the differential adhesion code is regulated by
the sonic hedgehog morphogen gradient. We propose that robust patterning during
tissue morphogenesis results from interplay between adhesion-based self-organization
and morphogen-directed patterning.

text: A look at international activities on Open Science reveals a broad spectrum
from individual institutional policies to national action plans. The present Recommendations
for a National Open Science Strategy in Austria are based on these international
initiatives and present practical considerations for their coordinated implementation
with regard to strategic developments in research, technology and innovation (RTI)
in Austria until 2030. They are addressed to all relevant actors in the RTI system,
in particular to Research Performing Organisations, Research Funding Organisations,
Research Policy, memory institutions such as Libraries and Researchers. The recommendation
paper was developed from 2018 to 2020 by the OANA working group "Open Science
Strategy" and published for the first time in spring 2020 for a public consultation.
The now available final version of the recommendation document, which contains
feedback and comments from the consultation, is intended to provide an impetus
for further discussion and implementation of Open Science in Austria and serves
as a contribution and basis for a potential national Open Science Strategy in
Austria. The document builds on the diverse expertise of the authors (academia,
administration, library and archive, information technology, science policy, funding
system, etc.) and reflects their personal experiences and opinions.

text: In the computation of the material properties of random alloys, the method
of 'special quasirandom structures' attempts to approximate the properties of
the alloy on a finite volume with higher accuracy by replicating certain statistics
of the random atomic lattice in the finite volume as accurately as possible. In
the present work, we provide a rigorous justification for a variant of this method
in the framework of the Thomas–Fermi–von Weizsäcker (TFW) model. Our approach
is based on a recent analysis of a related variance reduction method in stochastic
homogenization of linear elliptic PDEs and the locality properties of the TFW
model. Concerning the latter, we extend an exponential locality result by Nazar
and Ortner to include point charges, a result that may be of independent interest.

text: The brain represents and reasons probabilistically about complex stimuli and
motor actions using a noisy, spike-based neural code. A key building block for
such neural computations, as well as the basis for supervised and unsupervised
learning, is the ability to estimate the surprise or likelihood of incoming high-dimensional
neural activity patterns. Despite progress in statistical modeling of neural responses
and deep learning, current approaches either do not scale to large neural populations
or cannot be implemented using biologically realistic mechanisms. Inspired by
the sparse and random connectivity of real neuronal circuits, we present a model
for neural codes that accurately estimates the likelihood of individual spiking
patterns and has a straightforward, scalable, efficient, learnable, and realistic
neural implementation. This model’s performance on simultaneously recorded spiking
activity of >100 neurons in the monkey visual and prefrontal cortices is comparable
with or better than that of state-of-the-art models. Importantly, the model can
be learned using a small number of samples and using a local learning rule that
utilizes noise intrinsic to neural circuits. Slower, structural changes in random
connectivity, consistent with rewiring and pruning processes, further improve
the efficiency and sparseness of the resulting neural representations. Our results
merge insights from neuroanatomy, machine learning, and theoretical neuroscience
to suggest random sparse connectivity as a key design principle for neuronal computation.

text: In the high spin–orbit-coupled Sr2IrO4, the high sensitivity of the ground
state to the details of the local lattice structure shows a large potential for
the manipulation of the functional properties by inducing local lattice distortions.
We use epitaxial strain to modify the Ir–O bond geometry in Sr2IrO4 and perform
momentum-dependent resonant inelastic X-ray scattering (RIXS) at the metal and
at the ligand sites to unveil the response of the low-energy elementary excitations.
We observe that the pseudospin-wave dispersion for tensile-strained Sr2IrO4 films
displays large softening along the [h,0] direction, while along the [h,h] direction
it shows hardening. This evolution reveals a renormalization of the magnetic interactions
caused by a strain-driven cross-over from anisotropic to isotropic interactions
between the magnetic moments. Moreover, we detect dispersive electron–hole pair
excitations which shift to lower (higher) energies upon compressive (tensile)
strain, manifesting a reduction (increase) in the size of the charge gap. This
behavior shows an intimate coupling between charge excitations and lattice distortions
in Sr2IrO4, originating from the modified hopping elements between the t2g orbitals.
Our work highlights the central role played by the lattice degrees of freedom
in determining both the pseudospin and charge excitations of Sr2IrO4 and provides
valuable information toward the control of the ground state of complex oxides
in the presence of high spin–orbit coupling.

text: Translation termination is a finishing step of protein biosynthesis. The significant
role in this process belongs not only to protein factors of translation termination
but also to the nearest nucleotide environment of stop codons. There are numerous
descriptions of stop codons readthrough, which is due to specific nucleotide sequences
behind them. However, represented data are segmental and don’t explain the mechanism
of the nucleotide context influence on translation termination. It is well known
that stop codon UAA usage is preferential for A/T-rich genes, and UAG, UGA—for
G/C-rich genes, which is related to an expression level of these genes. We investigated
the connection between a frequency of nucleotides occurrence in 3' area of stop
codons in the human genome and their influence on translation termination efficiency.
We found that 3' context motif, which is cognate to the sequence of a stop codon,
stimulates translation termination. At the same time, the nucleotide composition
of 3' sequence that differs from stop codon, decreases translation termination
efficiency.

text: Translation termination is a finishing step of protein biosynthesis. The significant
role in this process belongs not only to protein factors of translation termination
but also to the nearest nucleotide environment of stop codons. There are numerous
descriptions of stop codons readthrough, which is due to specific nucleotide sequences
behind them. However, represented data are segmental and don’t explain the mechanism
of the nucleotide context influence on translation termination. It is well known
that stop codon UAA usage is preferential for A/T-rich genes, and UAG, UGA—for
G/C-rich genes, which is related to an expression level of these genes. We investigated
the connection between a frequency of nucleotides occurrence in 3' area of stop
codons in the human genome and their influence on translation termination efficiency.
We found that 3' context motif, which is cognate to the sequence of a stop codon,
stimulates translation termination. At the same time, the nucleotide composition
of 3' sequence that differs from stop codon, decreases translation termination
efficiency.

text: 'Even though Delaunay originally introduced his famous triangulations in the
case of infinite point sets with translational periodicity, a software that computes
such triangulations in the general case is not yet available, to the best of our
knowledge. Combining and generalizing previous work, we present a practical algorithm
for computing such triangulations. The algorithm has been implemented and experiments
show that its performance is as good as the one of the CGAL package, which is
restricted to cubic periodicity. '

text: Traditional robotic control suits require profound task-specific knowledge
for designing, building and testing control software. The rise of Deep Learning
has enabled end-to-end solutions to be learned entirely from data, requiring minimal
knowledge about the application area. We design a learning scheme to train end-to-end
linear dynamical systems (LDS)s by gradient descent in imitation learning robotic
domains. We introduce a new regularization loss component together with a learning
algorithm that improves the stability of the learned autonomous system, by forcing
the eigenvalues of the internal state updates of an LDS to be negative reals.
We evaluate our approach on a series of real-life and simulated robotic experiments,
in comparison to linear and nonlinear Recurrent Neural Network (RNN) architectures.
Our results show that our stabilizing method significantly improves test performance
of LDS, enabling such linear models to match the performance of contemporary nonlinear
RNN architectures. A video of the obstacle avoidance performance of our method
on a mobile robot, in unseen environments, compared to other methods can be viewed
at https://youtu.be/mhEsCoNao5E.

text: We consider the quantum mechanical many-body problem of a single impurity
particle immersed in a weakly interacting Bose gas. The impurity interacts with
the bosons via a two-body potential. We study the Hamiltonian of this system in
the mean-field limit and rigorously show that, at low energies, the problem is
well described by the Fröhlich polaron model.

text: Dynamic changes in the three-dimensional (3D) organization of chromatin are
associated with central biological processes, such as transcription, replication
and development. Therefore, the comprehensive identification and quantification
of these changes is fundamental to understanding of evolutionary and regulatory
mechanisms. Here, we present Comparison of Hi-C Experiments using Structural Similarity
(CHESS), an algorithm for the comparison of chromatin contact maps and automatic
differential feature extraction. We demonstrate the robustness of CHESS to experimental
variability and showcase its biological applications on (1) interspecies comparisons
of syntenic regions in human and mouse models; (2) intraspecies identification
of conformational changes in Zelda-depleted Drosophila embryos; (3) patient-specific
aberrant chromatin conformation in a diffuse large B-cell lymphoma sample; and
(4) the systematic identification of chromatin contact differences in high-resolution
Capture-C data. In summary, CHESS is a computationally efficient method for the
comparison and classification of changes in chromatin contact data.

text: Spontaneously arising channels that transport the phytohormone auxin provide
positional cues for self-organizing aspects of plant development such as flexible
vasculature regeneration or its patterning during leaf venation. The auxin canalization
hypothesis proposes a feedback between auxin signaling and transport as the underlying
mechanism, but molecular players await discovery. We identified part of the machinery
that routes auxin transport. The auxin-regulated receptor CAMEL (Canalization-related
Auxin-regulated Malectin-type RLK) together with CANAR (Canalization-related Receptor-like
kinase) interact with and phosphorylate PIN auxin transporters. camel and canar
mutants are impaired in PIN1 subcellular trafficking and auxin-mediated PIN polarization,
which macroscopically manifests as defects in leaf venation and vasculature regeneration
after wounding. The CAMEL-CANAR receptor complex is part of the auxin feedback
that coordinates polarization of individual cells during auxin canalization.

text: "Load imbalance pervasively exists in distributed deep learning training systems,
either caused by the inherent imbalance in learned tasks or by the system itself.
Traditional synchronous Stochastic Gradient Descent (SGD)\r\nachieves good accuracy
for a wide variety of tasks, but relies on global synchronization to accumulate
the gradients at every training step. In this paper, we propose eager-SGD, which
relaxes the global synchronization for\r\ndecentralized accumulation. To implement
eager-SGD, we propose to use two partial collectives: solo and majority. With
solo allreduce, the faster processes contribute their gradients eagerly without
waiting for the slower processes, whereas with majority allreduce, at least half
of the participants must contribute gradients before continuing, all without using
a central parameter server. We theoretically prove the convergence of the algorithms
and describe the partial collectives in detail. Experimental results on load-imbalanced
environments (CIFAR-10, ImageNet, and UCF101 datasets) show\r\nthat eager-SGD
achieves 1.27x speedup over the state-of-the-art synchronous SGD, without losing
accuracy."
