text: We report the synthesis and characterization of graphene functionalized with
iron (Fe3+) oxide (G-Fe3O4) nanohybrids for radio-frequency magnetic hyperthermia
application. We adopted the wet chemical procedure, using various contents of
Fe3O4 (magnetite) from 0–100% for making two-dimensional graphene–Fe3O4 nanohybrids.
The homogeneous dispersal of Fe3O4 nanoparticles decorated on the graphene surface
combined with their biocompatibility and high thermal conductivity make them an
excellent material for magnetic hyperthermia. The morphological and magnetic properties
of the nanohybrids were studied using scanning electron microscopy (SEM) and a
vibrating sample magnetometer (VSM), respectively. The smart magnetic platforms
were exposed to an alternating current (AC) magnetic field of 633 kHz and of strength
9.1 mT for studying their hyperthermic performance. The localized antitumor effects
were investigated with artificial neural network modeling. A neural net time-series
model was developed for the assessment of the best nanohybrid composition to serve
the purpose with an accuracy close to 100%. Six Nonlinear Autoregressive with
External Input (NARX) models were obtained, one for each of the components. The
assessment of the accuracy of the predicted results has been done on the basis
of Mean Squared Error (MSE). The highest Mean Squared Error value was obtained
for the nanohybrid containing 45% magnetite and 55% graphene (F45G55) in the training
phase i.e., 0.44703, which is where the model achieved optimal results after 71
epochs. The F45G55 nanohybrid was found to be the best for hyperthermia applications
in low dosage with the highest specific absorption rate (SAR) and mean squared
error values.

text: We present conductance-matrix measurements in long, three-terminal hybrid
superconductor-semiconductor nanowires, and compare with theoretical predictions
of a magnetic-field-driven, topological quantum phase transition. By examining
the nonlocal conductance, we identify the closure of the excitation gap in the
bulk of the semiconductor before the emergence of zero-bias peaks, ruling out
spurious gap-closure signatures from localized states. We observe that after the
gap closes, nonlocal signals and zero-bias peaks fluctuate strongly at both ends,
inconsistent with a simple picture of clean topological superconductivity.

text: As the size and complexity of models and datasets grow, so does the need for
communication-efficient variants of stochastic gradient descent that can be deployed
to perform parallel model training. One popular communication-compression method
for data-parallel SGD is QSGD (Alistarh et al., 2017), which quantizes and encodes
gradients to reduce communication costs. The baseline variant of QSGD provides
strong theoretical guarantees, however, for practical purposes, the authors proposed
a heuristic variant which we call QSGDinf, which demonstrated impressive empirical
gains for distributed training of large neural networks. In this paper, we build
on this work to propose a new gradient quantization scheme, and show that it has
both stronger theoretical guarantees than QSGD, and matches and exceeds the empirical
performance of the QSGDinf heuristic and of other compression methods.

text: The convex grabbing game is a game where two players, Alice and Bob, alternate
taking extremal points from the convex hull of a point set on the plane. Rational
weights are given to the points. The goal of each player is to maximize the total
weight over all points that they obtain. We restrict the setting to the case of
binary weights. We show a construction of an arbitrarily large odd-sized point
set that allows Bob to obtain almost 3/4 of the total weight. This construction
answers a question asked by Matsumoto, Nakamigawa, and Sakuma in [Graphs and Combinatorics,
36/1 (2020)]. We also present an arbitrarily large even-sized point set where
Bob can obtain the entirety of the total weight. Finally, we discuss conjectures
about optimum moves in the convex grabbing game for both players in general.

text: 'In mammalian genomes, differentially methylated regions (DMRs) and histone
marks including trimethylation of histone 3 lysine 27 (H3K27me3) at imprinted
genes are asymmetrically inherited to control parentally-biased gene expression.
However, neither parent-of-origin-specific transcription nor imprints have been
comprehensively mapped at the blastocyst stage of preimplantation development.
Here, we address this by integrating transcriptomic and epigenomic approaches
in mouse preimplantation embryos. We find that seventy-one genes exhibit previously
unreported parent-of-origin-specific expression in blastocysts (nBiX: novel blastocyst-imprinted
expressed). Uniparental expression of nBiX genes disappears soon after implantation.
Micro-whole-genome bisulfite sequencing (µWGBS) of individual uniparental blastocysts
detects 859 DMRs. We further find that 16% of nBiX genes are associated with a
DMR, whereas most are associated with parentally-biased H3K27me3, suggesting a
role for Polycomb-mediated imprinting in blastocysts. nBiX genes are clustered:
five clusters contained at least one published imprinted gene, and five clusters
exclusively contained nBiX genes. These data suggest that early development undergoes
a complex program of stage-specific imprinting involving different tiers of regulation.'

text: "An ordered graph is a graph with a linear ordering on its vertex set. We
prove that for every positive integer k, there exists a constant ck > 0 such that
any ordered graph G on n vertices with the property that neither G nor its complement
contains an induced monotone path of size k, has either a clique or an independent
set of size at least n^ck . This strengthens a result of Bousquet, Lagoutte, and
Thomassé, who proved the analogous result for unordered graphs.\r\nA key idea
of the above paper was to show that any unordered graph on n vertices that does
not contain an induced path of size k, and whose maximum degree is at most c(k)n
for some small c(k) > 0, contains two disjoint linear size subsets with no edge
between them. This approach fails for ordered graphs, because the analogous statement
is false for k ≥ 3, by a construction of Fox. We provide some further examples
showing that this statement also fails for ordered graphs avoiding other ordered
trees."

text: Mosaic analysis with double markers (MADM) offers one approach to visualize
and concomitantly manipulate genetically defined cells in mice with single-cell
resolution. MADM applications include the analysis of lineage, single-cell morphology
and physiology, genomic imprinting phenotypes, and dissection of cell-autonomous
gene functions in vivo in health and disease. Yet, MADM can only be applied to
<25% of all mouse genes on select chromosomes to date. To overcome this limitation,
we generate transgenic mice with knocked-in MADM cassettes near the centromeres
of all 19 autosomes and validate their use across organs. With this resource,
>96% of the entire mouse genome can now be subjected to single-cell genetic mosaic
analysis. Beyond a proof of principle, we apply our MADM library to systematically
trace sister chromatid segregation in distinct mitotic cell lineages. We find
striking chromosome-specific biases in segregation patterns, reflecting a putative
mechanism for the asymmetric segregation of genetic determinants in somatic stem
cell division.

text: Generalizing Lee’s inductive argument for counting the cells of higher order
Voronoi tessellations in ℝ² to ℝ³, we get precise relations in terms of Morse
theoretic quantities for piecewise constant functions on planar arrangements.
Specifically, we prove that for a generic set of n ≥ 5 points in ℝ³, the number
of regions in the order-k Voronoi tessellation is N_{k-1} - binom(k,2)n + n, for
1 ≤ k ≤ n-1, in which N_{k-1} is the sum of Euler characteristics of these function’s
first k-1 sublevel sets. We get similar expressions for the vertices, edges, and
polygons of the order-k Voronoi tessellation.

text: 'Given a finite set A ⊂ ℝ^d, let Cov_{r,k} denote the set of all points within
distance r to at least k points of A. Allowing r and k to vary, we obtain a 2-parameter
family of spaces that grow larger when r increases or k decreases, called the
multicover bifiltration. Motivated by the problem of computing the homology of
this bifiltration, we introduce two closely related combinatorial bifiltrations,
one polyhedral and the other simplicial, which are both topologically equivalent
to the multicover bifiltration and far smaller than a Čech-based model considered
in prior work of Sheehy. Our polyhedral construction is a bifiltration of the
rhomboid tiling of Edelsbrunner and Osang, and can be efficiently computed using
a variant of an algorithm given by these authors as well. Using an implementation
for dimension 2 and 3, we provide experimental results. Our simplicial construction
is useful for understanding the polyhedral construction and proving its correctness. '

text: Sound propagation is a macroscopic manifestation of the interplay between
the equilibrium thermodynamics and the dynamical transport properties of fluids.
Here, for a two-dimensional system of ultracold fermions, we calculate the first
and second sound velocities across the whole BCS-BEC crossover, and we analyze
the system response to an external perturbation. In the low-temperature regime
we reproduce the recent measurements [Phys. Rev. Lett. 124, 240403 (2020)] of
the first sound velocity, which, due to the decoupling of density and entropy
fluctuations, is the sole mode excited by a density probe. Conversely, a heat
perturbation excites only the second sound, which, being sensitive to the superfluid
depletion, vanishes in the deep BCS regime and jumps discontinuously to zero at
the Berezinskii-Kosterlitz-Thouless superfluid transition. A mixing between the
modes occurs only in the finite-temperature BEC regime, where our theory converges
to the purely bosonic results.

text: The control of nonequilibrium quantum dynamics in many-body systems is challenging
because interactions typically lead to thermalization and a chaotic spreading
throughout Hilbert space. We investigate nonequilibrium dynamics after rapid quenches
in a many-body system composed of 3 to 200 strongly interacting qubits in one
and two spatial dimensions. Using a programmable quantum simulator based on Rydberg
atom arrays, we show that coherent revivals associated with so-called quantum
many-body scars can be stabilized by periodic driving, which generates a robust
subharmonic response akin to discrete time-crystalline order. We map Hilbert space
dynamics, geometry dependence, phase diagrams, and system-size dependence of this
emergent phenomenon, demonstrating new ways to steer complex dynamics in many-body
systems and enabling potential applications in quantum information science.

text: "In this note, we introduce a distributed twist on the classic coupon collector
problem: a set of m collectors wish to each obtain a set of n coupons; for this,
they can each sample coupons uniformly at random, but can also meet in pairwise
interactions, during which they can exchange coupons. By doing so, they hope to
reduce the number of coupons that must be sampled by each collector in order to
obtain a full set. This extension is natural when considering real-world manifestations
of the coupon collector phenomenon, and has been remarked upon and studied empirically
(Hayes and Hannigan 2006, Ahmad et al. 2014, Delmarcelle 2019).\r\n\r\nWe provide
the first theoretical analysis for such a scenario. We find that “coupon collecting
with friends” can indeed significantly reduce the number of coupons each collector
must sample, and raises interesting connections to the more traditional variants
of the problem. While our analysis is in most cases asymptotically tight, there
are several open questions raised, regarding finer-grained analysis of both “coupon
collecting with friends,” and of a long-studied variant of the original problem
in which a collector requires multiple full sets of coupons."

text: "Cytoplasmic reorganizations are essential for morphogenesis. In large cells
like oocytes, these reorganizations become crucial in patterning the oocyte for
later stages of embryonic development. Ascidians oocytes reorganize their cytoplasm
(ooplasm) in a spectacular manner. Ooplasmic reorganization is initiated at fertilization
with the contraction of the actomyosin cortex along the animal-vegetal axis of
the oocyte, driving the accumulation of cortical endoplasmic reticulum (cER),
maternal mRNAs associated to it and a mitochondria-rich subcortical layer – the
myoplasm – in a region of the vegetal pole termed contraction pole (CP). Here
we have used the species Phallusia mammillata to investigate the changes in cell
shape that accompany these reorganizations and the mechanochemical mechanisms
underlining CP formation.\r\nWe report that the length of the animal-vegetal (AV)
axis oscillates upon fertilization: it first undergoes a cycle of fast elongation-lengthening
followed by a slow expansion of mainly the vegetal pole (VP) of the cell. We show
that the fast oscillation corresponds to a dynamic polarization of the actin cortex
as a result of a fertilization-induced increase in cortical tension in the oocyte
that triggers a rupture of the cortex at the animal pole and the establishment
of vegetal-directed cortical flows. These flows are responsible for the vegetal
accumulation of actin causing the VP to flatten. \r\nWe find that the slow expansion
of the VP, leading to CP formation, correlates with a relaxation of the vegetal
cortex and that the myoplasm plays a role in the expansion. We show that the myoplasm
is a solid-like layer that buckles under compression forces arising from the contracting
actin cortex at the VP. Straightening of the myoplasm when actin flows stops,
facilitates the expansion of the VP and the CP. Altogether, our results present
a previously unrecognized role for the myoplasm in ascidian ooplasmic segregation.

text: SnSe, a wide-bandgap semiconductor, has attracted significant attention from
the thermoelectric (TE) community due to its outstanding TE performance deriving
from the ultralow thermal conductivity and advantageous electronic structures.
Here, we promoted the TE performance of n-type SnSe polycrystals through bandgap
engineering and vacancy compensation. We found that PbTe can significantly reduce
the wide bandgap of SnSe to reduce the impurity transition energy, largely enhancing
the carrier concentration. Also, PbTe-induced crystal symmetry promotion increases
the carrier mobility, preserving large Seebeck coefficient. Consequently, a maximum
ZT of ∼1.4 at 793 K is obtained in Br doped SnSe–13%PbTe. Furthermore, we found
that extra Sn in n-type SnSe can compensate for the intrinsic Sn vacancies and
form electron donor-like metallic Sn nanophases. The Sn nanophases near the grain
boundary could also reduce the intergrain energy barrier which largely enhances
the carrier mobility. As a result, a maximum ZT value of ∼1.7 at 793 K and an
average ZT (ZTave) of ∼0.58 in 300–793 K are achieved in Br doped Sn1.08Se–13%PbTe.
Our findings provide a novel strategy to promote the TE performance in wide-bandgap
semiconductors.

text: "We compute the deficiency spaces of operators of the form \U0001D43B\U0001D434⊗̂
\U0001D43C+\U0001D43C⊗̂ \U0001D43B\U0001D435, for symmetric \U0001D43B\U0001D434

extensions (if they exist) by means of von Neumann's theory. The structure of
the deficiency spaces for this case was asserted already in Ibort et al. [Boundary
dynamics driven entanglement, J. Phys. A: Math. Theor. 47(38) (2014) 385301],
but only proven under the restriction of \U0001D43B\U0001D435 having discrete,

text: Intestinal organoids derived from single cells undergo complex crypt–villus
patterning and morphogenesis. However, the nature and coordination of the underlying
forces remains poorly characterized. Here, using light-sheet microscopy and large-scale
imaging quantification, we demonstrate that crypt formation coincides with a stark
reduction in lumen volume. We develop a 3D biophysical model to computationally
screen different mechanical scenarios of crypt morphogenesis. Combining this with
live-imaging data and multiple mechanical perturbations, we show that actomyosin-driven
crypt apical contraction and villus basal tension work synergistically with lumen
volume reduction to drive crypt morphogenesis, and demonstrate the existence of
a critical point in differential tensions above which crypt morphology becomes
robust to volume changes. Finally, we identified a sodium/glucose cotransporter
that is specific to differentiated enterocytes that modulates lumen volume reduction
through cell swelling in the villus region. Together, our study uncovers the cellular
basis of how cell fate modulates osmotic and actomyosin forces to coordinate robust
morphogenesis.

text: 'Selection and random drift determine the probability that novel mutations
fixate in a population. Population structure is known to affect the dynamics of
the evolutionary process. Amplifiers of selection are population structures that
increase the fixation probability of beneficial mutants compared to well-mixed
populations. Over the past 15 years, extensive research has produced remarkable
structures called strong amplifiers which guarantee that every beneficial mutation
fixates with high probability. But strong amplification has come at the cost of
considerably delaying the fixation event, which can slow down the overall rate
of evolution. However, the precise relationship between fixation probability and
time has remained elusive. Here we characterize the slowdown effect of strong
amplification. First, we prove that all strong amplifiers must delay the fixation
event at least to some extent. Second, we construct strong amplifiers that delay
the fixation event only marginally as compared to the well-mixed populations.
Our results thus establish a tight relationship between fixation probability and
time: Strong amplification always comes at a cost of a slowdown, but more than
a marginal slowdown is not needed.'

text: At the encounter with a novel environment, contextual memory formation is
greatly enhanced, accompanied with increased arousal and active exploration. Although
this phenomenon has been widely observed in animal and human daily life, how the
novelty in the environment is detected and contributes to contextual memory formation
has lately started to be unveiled. The hippocampus has been studied for many decades
for its largely known roles in encoding spatial memory, and a growing body of
evidence indicates a differential involvement of dorsal and ventral hippocampal
divisions in novelty detection. In this brief review article, we discuss the recent
findings of the role of mossy cells in the ventral hippocampal moiety in novelty
detection and put them in perspective with other novelty-related pathways in the
hippocampus. We propose a mechanism for novelty-driven memory acquisition in the
dentate gyrus by the direct projection of ventral mossy cells to dorsal dentate
granule cells. By this projection, the ventral hippocampus sends novelty signals
to the dorsal hippocampus, opening a gate for memory encoding in dentate granule
cells based on information coming from the entorhinal cortex. We conclude that,
contrary to the presently accepted functional independence, the dorsal and ventral
hippocampi cooperate to link the novelty and contextual information, and this
dorso-ventral interaction is crucial for the novelty-dependent memory formation.

text: Perineuronal nets (PNNs), components of the extracellular matrix, preferentially
coat parvalbumin-positive interneurons and constrain critical-period plasticity
in the adult cerebral cortex. Current strategies to remove PNN are long-lasting,
invasive, and trigger neuropsychiatric symptoms. Here, we apply repeated anesthetic
ketamine as a method with minimal behavioral effect. We find that this paradigm
strongly reduces PNN coating in the healthy adult brain and promotes juvenile-like
plasticity. Microglia are critically involved in PNN loss because they engage
with parvalbumin-positive neurons in their defined cortical layer. We identify
external 60-Hz light-flickering entrainment to recapitulate microglia-mediated
PNN removal. Importantly, 40-Hz frequency, which is known to remove amyloid plaques,
does not induce PNN loss, suggesting microglia might functionally tune to distinct
brain frequencies. Thus, our 60-Hz light-entrainment strategy provides an alternative
form of PNN intervention in the healthy adult brain.
