text: In laboratory studies and numerical simulations, we observe clear signatures
of unstable time-periodic solutions in a moderately turbulent quasi-two-dimensional
flow. We validate the dynamical relevance of such solutions by demonstrating that
turbulent flows in both experiment and numerics transiently display time-periodic
dynamics when they shadow unstable periodic orbits (UPOs). We show that UPOs we
computed are also statistically significant, with turbulent flows spending a sizable
fraction of the total time near these solutions. As a result, the average rates
of energy input and dissipation for the turbulent flow and frequently visited
UPOs differ only by a few percent.

text: 'Epistasis, the context-dependence of the contribution of an amino acid substitution
to fitness, is common in evolution. To detect epistasis, fitness must be measured
for at least four genotypes: the reference genotype, two different single mutants
and a double mutant with both of the single mutations. For higher-order epistasis
of the order n, fitness has to be measured for all 2n genotypes of an n-dimensional
hypercube in genotype space forming a ‘combinatorially complete dataset’. So far,
only a handful of such datasets have been produced by manual curation. Concurrently,
random mutagenesis experiments have produced measurements of fitness and other
phenotypes in a high-throughput manner, potentially containing a number of combinatorially
complete datasets. We present an effective recursive algorithm for finding all
hypercube structures in random mutagenesis experimental data. To test the algorithm,
we applied it to the data from a recent HIS3 protein dataset and found all 199
847 053 unique combinatorially complete genotype combinations of dimensionality
ranging from 2 to 12. The algorithm may be useful for researchers looking for
higher-order epistasis in their high-throughput experimental data.'

text: Nature creates electrons with two values of the spin projection quantum number.
In certain applications, it is important to filter electrons with one spin projection
from the rest. Such filtering is not trivial, since spin-dependent interactions
are often weak, and cannot lead to any substantial effect. Here we propose an
efficient spin filter based upon scattering from a two-dimensional crystal, which
is made of aligned point magnets. The polarization of the outgoing electron flux
is controlled by the crystal, and reaches maximum at specific values of the parameters.
In our scheme, polarization increase is accompanied by higher reflectivity of
the crystal. High transmission is feasible in scattering from a quantum cavity
made of two crystals. Our findings can be used for studies of low-energy spin-dependent
scattering from two-dimensional ordered structures made of magnetic atoms or aligned
chiral molecules.

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: 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: 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: 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: 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."

text: "The design and implementation of efficient concurrent data structures have\r\nseen
significant attention. However, most of this work has focused on\r\nconcurrent
data structures providing good \\emph{worst-case} guarantees. In real\r\nworkloads,
objects are often accessed at different rates, since access\r\ndistributions may
be non-uniform. Efficient distribution-adaptive data\r\nstructures are known in
the sequential case, e.g. the splay-trees; however,\r\nthey often are hard to
translate efficiently in the concurrent case.\r\n In this paper, we investigate
distribution-adaptive concurrent data\r\nstructures and propose a new design called
the splay-list. At a high level, the\r\nsplay-list is similar to a standard skip-list,
with the key distinction that\r\nthe height of each element adapts dynamically
to its access rate: popular\r\nelements ``move up,'' whereas rarely-accessed elements
decrease in height. We\r\nshow that the splay-list provides order-optimal amortized
complexity bounds for\r\na subset of operations while being amenable to efficient
concurrent\r\nimplementation. Experimental results show that the splay-list can
leverage\r\ndistribution-adaptivity to improve on the performance of classic concurrent\r\ndesigns,
and can outperform the only previously-known distribution-adaptive\r\ndesign in
certain settings."

text: Several realistic spin-orbital models for transition metal oxides go beyond
the classical expectations and could be understood only by employing the quantum
entanglement. Experiments on these materials confirm that spin-orbital entanglement
has measurable consequences. Here, we capture the essential features of spin-orbital
entanglement in complex quantum matter utilizing 1D spin-orbital model which accommodates
SU(2)⊗SU(2) symmetric Kugel-Khomskii superexchange as well as the Ising on-site
spin-orbit coupling. Building on the results obtained for full and effective models
in the regime of strong spin-orbit coupling, we address the question whether the
entanglement found on superexchange bonds always increases when the Ising spin-orbit
coupling is added. We show that (i) quantum entanglement is amplified by strong
spin-orbit coupling and, surprisingly, (ii) almost classical disentangled states
are possible. We complete the latter case by analyzing how the entanglement existing
for intermediate values of spin-orbit coupling can disappear for higher values
of this coupling.

text: "Research in the field of colloidal semiconductor nanocrystals (NCs) has progressed
tremendously, mostly because of their exceptional optoelectronic properties. Core@shell
NCs, in which one or more inorganic layers overcoat individual NCs, recently received
significant attention due to their remarkable optical characteristics. Reduced
Auger recombination, suppressed blinking, and enhanced carrier multiplication
are among the merits of core@shell NCs. Despite their importance in device development,
the influence of the shell and the surface modification of the core@shell NC assemblies
on the charge carrier transport remains a pertinent research objective. Type-II
PbTe@PbS core@shell NCs, in which exclusive electron transport was demonstrated,
still exhibit instability of their electron \r\n ransport. Here, we demonstrate
the enhancement of electron transport and stability in PbTe@PbS core@shell NC
assemblies using iodide as a surface passivating ligand. The combination of the
PbS shelling and the use of the iodide ligand contributes to the addition of one
mobile electron for each core@shell NC. Furthermore, both electron mobility and
on/off current modulation ratio values of the core@shell NC field-effect transistor
are steady with the usage of iodide. Excellent stability in these exclusively
electron-transporting core@shell NCs paves the way for their utilization in electronic
devices. "

text: "Appropriately designed nanocomposites allow improving the thermoelectric
performance by several mechanisms, including phonon scattering, modulation doping
and energy filtering, while additionally promoting better mechanical properties
than those of crystalline materials. Here, a strategy for producing Bi2Te3–Cu2xTe
nanocomposites based on the consolidation of heterostructured nanoparticles is
described and the thermoelectric properties of the obtained materials are investigated.
We first detail a two-step solution-based process to produce Bi2Te3–Cu2xTe heteronanostructures,
based on the growth of Cu2xTe nanocrystals on the surface of Bi2Te3 nanowires.
We characterize the structural and chemical properties of the synthesized nanostructures
and of the nanocomposites\r\nproduced by hot-pressing the particles at moderate
temperatures. Besides, the transport properties of the nanocomposites are investigated
as a function of the amount of Cu introduced. Overall, the presence of Cu decreases
the material thermal conductivity through promotion of phonon scattering, modulates
the charge carrier concentration through electron spillover, and increases the
Seebeck coefficient through filtering of charge carriers at energy barriers. These
effects result in an improvement of over 50% of the thermoelectric figure of merit
of Bi2Te3."

text: "Efficiently handling time-triggered and possibly nondeterministic switches\r\nfor
hybrid systems reachability is a challenging task. In this paper we present\r\nan
approach based on conservative set-based enclosure of the dynamics that can\r\nhandle
systems with uncertain parameters and inputs, where the uncertainties\r\nare bound
to given intervals. The method is evaluated on the plant model of an\r\nexperimental
electro-mechanical braking system with periodic controller. In\r\nthis model,
the fast-switching controller dynamics requires simulation time\r\nscales of the
order of nanoseconds. Accurate set-based computations for\r\nrelatively large
time horizons are known to be expensive. However, by\r\nappropriately decoupling
the time variable with respect to the spatial\r\nvariables, and enclosing the
uncertain parameters using interval matrix maps\r\nacting on zonotopes, we show
that the computation time can be lowered to 5000\r\ntimes faster with respect
to previous works. This is a step forward in formal\r\nverification of hybrid
systems because reduced run-times allow engineers to\r\nintroduce more expressiveness
in their models with a relatively inexpensive\r\ncomputational cost."
