text: Deep learning at scale is dominated by communication time. Distributing samples
across nodes usually yields the best performance, but poses scaling challenges
due to global information dissemination and load imbalance across uneven sample
lengths. State-of-the-art decentralized optimizers mitigate the problem, but require
more iterations to achieve the same accuracy as their globally-communicating counterparts.
We present Wait-Avoiding Group Model Averaging (WAGMA) SGD, a wait-avoiding stochastic
optimizer that reduces global communication via subgroup weight exchange. The
key insight is a combination of algorithmic changes to the averaging scheme and
the use of a group allreduce operation. We prove the convergence of WAGMA-SGD,
and empirically show that it retains convergence rates similar to Allreduce-SGD.
For evaluation, we train ResNet-50 on ImageNet; Transformer for machine translation;
and deep reinforcement learning for navigation at scale. Compared with state-of-the-art
decentralized SGD variants, WAGMA-SGD significantly improves training throughput
(e.g., 2.1× on 1,024 GPUs for reinforcement learning), and achieves the fastest
time-to-solution (e.g., the highest score using the shortest training time for
Transformer).

text: P-glycoprotein (ABCB1) and breast cancer resistance protein (ABCG2) restrict
at the blood–brain barrier (BBB) the brain distribution of the majority of currently
known molecularly targeted anticancer drugs. To improve brain delivery of dual
ABCB1/ABCG2 substrates, both ABCB1 and ABCG2 need to be inhibited simultaneously
at the BBB. We examined the feasibility of simultaneous ABCB1/ABCG2 inhibition
with i.v. co-infusion of erlotinib and tariquidar by studying brain distribution
of the model ABCB1/ABCG2 substrate [11C]erlotinib in mice and rhesus macaques
with PET. Tolerability of the erlotinib/tariquidar combination was assessed in
human embryonic stem cell-derived cerebral organoids. In mice and macaques, baseline
brain distribution of [11C]erlotinib was low (brain distribution volume, VT,brain < 0.3 mL/cm3).
Co-infusion of erlotinib and tariquidar increased VT,brain in mice by 3.0-fold
and in macaques by 3.4- to 5.0-fold, while infusion of erlotinib alone or tariquidar
alone led to less pronounced VT,brain increases in both species. Treatment of
cerebral organoids with erlotinib/tariquidar led to an induction of Caspase-3-dependent
apoptosis. Co-infusion of erlotinib/tariquidar may potentially allow for complete
ABCB1/ABCG2 inhibition at the BBB, while simultaneously achieving brain-targeted
EGFR inhibition. Our protocol may be applicable to enhance brain delivery of molecularly
targeted anticancer drugs for a more effective treatment of brain tumors.

text: We develop a version of Ekedahl’s geometric sieve for integral quadratic forms
of rank at least five. As one ranges over the zeros of such quadratic forms, we
use the sieve to compute the density of coprime values of polynomials, and furthermore,
to address a question about local solubility in families of varieties parameterised
by the zeros.

text: 'Montane cloud forests are areas of high endemism, and are one of the more
vulnerable terrestrial ecosystems to climate change. Thus, understanding how they
both contribute to the generation of biodiversity, and will respond to ongoing
climate change, are important and related challenges. The widely accepted model
for montane cloud forest dynamics involves upslope forcing of their range limits
with global climate warming. However, limited climate data provides some support
for an alternative model, where range limits are forced downslope with climate
warming. Testing between these two models is challenging, due to the inherent
limitations of climate and pollen records. We overcome this with an alternative
source of historical information, testing between competing model predictions
using genomic data and demographic analyses for a species of beetle tightly associated
to an oceanic island cloud forest. Results unequivocally support the alternative
model: populations that were isolated at higher elevation peaks during the Last
Glacial Maximum are now in contact and hybridizing at lower elevations. Our results
suggest that genomic data are a rich source of information to further understand
how montane cloud forest biodiversity originates, and how it is likely to be impacted
by ongoing climate change.'

text: Let g be a complex semisimple Lie algebra. We give a classification of contravariant
forms on the nondegenerate Whittaker g-modules Y(χ,η) introduced by Kostant. We
prove that the set of all contravariant forms on Y(χ,η) forms a vector space whose
dimension is given by the cardinality of the Weyl group of g. We also describe
a procedure for parabolically inducing contravariant forms. As a corollary, we
deduce the existence of the Shapovalov form on a Verma module, and provide a formula
for the dimension of the space of contravariant forms on the degenerate Whittaker
modules M(χ,η) introduced by McDowell.

text: This paper is concerned with a non-isothermal Cahn-Hilliard model based on
a microforce balance. The model was derived by A. Miranville and G. Schimperna
starting from the two fundamental laws of Thermodynamics, following M. Gurtin's
two-scale approach. The main working assumptions are made on the behaviour of
the heat flux as the absolute temperature tends to zero and to infinity. A suitable
Ginzburg-Landau free energy is considered. Global-in-time existence for the initial-boundary
value problem associated to the entropy formulation and, in a subcase, also to
the weak formulation of the model is proved by deriving suitable a priori estimates
and by showing weak sequential stability of families of approximating solutions.
At last, some highlights are given regarding a possible approximation scheme compatible
with the a-priori estimates available for the system.

text: We study optimal election sequences for repeatedly selecting a (very) small
group of leaders among a set of participants (players) with publicly known unique
ids. In every time slot, every player has to select exactly one player that it
considers to be the current leader, oblivious to the selection of the other players,
but with the overarching goal of maximizing a given parameterized global (“social”)
payoff function in the limit. We consider a quite generic model, where the local
payoff achieved by a given player depends, weighted by some arbitrary but fixed
real parameter, on the number of different leaders chosen in a round, the number
of players that choose the given player as the leader, and whether the chosen
leader has changed w.r.t. the previous round or not. The social payoff can be
the maximum, average or minimum local payoff of the players. Possible applications
include quite diverse examples such as rotating coordinator-based distributed
algorithms and long-haul formation flying of social birds. Depending on the weights
and the particular social payoff, optimal sequences can be very different, from
simple round-robin where all players chose the same leader alternatingly every
time slot to very exotic patterns, where a small group of leaders (at most 2)
is elected in every time slot. Moreover, we study the question if and when a single
player would not benefit w.r.t. its local payoff when deviating from the given
optimal sequence, i.e., when our optimal sequences are Nash equilibria in the
restricted strategy space of oblivious strategies. As this is the case for many
parameterizations of our model, our results reveal that no punishment is needed
to make it rational for the players to optimize the social payoff.

text: Area-dependent quantum field theory is a modification of two-dimensional topological
quantum field theory, where one equips each connected component of a bordism with
a positive real number—interpreted as area—which behaves additively under glueing.
As opposed to topological theories, in area-dependent theories the state spaces
can be infinite-dimensional. We introduce the notion of regularised Frobenius
algebras in Hilbert spaces and show that area-dependent theories are in one-to-one
correspondence to commutative regularised Frobenius algebras. We also provide
a state sum construction for area-dependent theories. Our main example is two-dimensional
Yang–Mills theory with compact gauge group, which we treat in detail.

text: The paper introduces an inertial extragradient subgradient method with self-adaptive
step sizes for solving equilibrium problems in real Hilbert spaces. Weak convergence
of the proposed method is obtained under the condition that the bifunction is
pseudomonotone and Lipchitz continuous. Linear convergence is also given when
the bifunction is strongly pseudomonotone and Lipchitz continuous. Numerical implementations
and comparisons with other related inertial methods are given using test problems
including a real-world application to Nash–Cournot oligopolistic electricity market
equilibrium model.

text: The hippocampus has a major role in encoding and consolidating long-term memories,
and undergoes plastic changes during sleep1. These changes require precise homeostatic
control by subcortical neuromodulatory structures2. The underlying mechanisms
of this phenomenon, however, remain unknown. Here, using multi-structure recordings
in macaque monkeys, we show that the brainstem transiently modulates hippocampal
network events through phasic pontine waves known as pontogeniculooccipital waves
(PGO waves). Two physiologically distinct types of PGO wave appear to occur sequentially,
selectively influencing high-frequency ripples and low-frequency theta events,
respectively. The two types of PGO wave are associated with opposite hippocampal
spike-field coupling, prompting periods of high neural synchrony of neural populations
during periods of ripple and theta instances. The coupling between PGO waves and
ripples, classically associated with distinct sleep stages, supports the notion
that a global coordination mechanism of hippocampal sleep dynamics by cholinergic
pontine transients may promote systems and synaptic memory consolidation as well
as synaptic homeostasis.

text: Plants are able to orient their growth according to gravity, which ultimately
controls both shoot and root architecture.1 Gravitropism is a dynamic process
whereby gravistimulation induces the asymmetric distribution of the plant hormone
auxin, leading to asymmetric growth, organ bending, and subsequent reset of auxin
distribution back to the original pre-gravistimulation situation.1, 2, 3 Differential
auxin accumulation during the gravitropic response depends on the activity of
polarly localized PIN-FORMED (PIN) auxin-efflux carriers.1, 2, 3, 4 In particular,
the timing of this dynamic response is regulated by PIN2,5,6 but the underlying
molecular mechanisms are poorly understood. Here, we show that MEMBRANE ASSOCIATED
KINASE REGULATOR2 (MAKR2) controls the pace of the root gravitropic response.
We found that MAKR2 is required for the PIN2 asymmetry during gravitropism by
acting as a negative regulator of the cell-surface signaling mediated by the receptor-like
kinase TRANSMEMBRANE KINASE1 (TMK1).2,7, 8, 9, 10 Furthermore, we show that
the MAKR2 inhibitory effect on TMK1 signaling is antagonized by auxin itself,
which triggers rapid MAKR2 membrane dissociation in a TMK1-dependent manner. Our
findings suggest that the timing of the root gravitropic response is orchestrated
by the reversible inhibition of the TMK1 signaling pathway at the cell surface.

text: Spin qubits are considered to be among the most promising candidates for building
a quantum processor. Group IV hole spin qubits have moved into the focus of interest
due to the ease of operation and compatibility with Si technology. In addition,
Ge offers the option for monolithic superconductor-semiconductor integration.
Here we demonstrate a hole spin qubit operating at fields below 10 mT, the critical
field of Al, by exploiting the large out-of-plane hole g-factors in planar Ge
and by encoding the qubit into the singlet-triplet states of a double quantum
dot. We observe electrically controlled X and Z-rotations with tunable frequencies
exceeding 100 MHz and dephasing times of 1μs which we extend beyond 15μs with
echo techniques. These results show that Ge hole singlet triplet qubits outperform
their electronic Si and GaAs based counterparts in speed and coherence, respectively.
In addition, they are on par with Ge single spin qubits, but can be operated at
much lower fields underlining their potential for on chip integration with superconducting
technologies.

text: A semiconducting nanowire fully wrapped by a superconducting shell has been
proposed as a platform for obtaining Majorana modes at small magnetic fields.
In this study, we demonstrate that the appearance of subgap states in such structures
is actually governed by the junction region in tunneling spectroscopy measurements
and not the full-shell nanowire itself. Short tunneling regions never show subgap
states, whereas longer junctions always do. This can be understood in terms of
quantum dots forming in the junction and hosting Andreev levels in the Yu-Shiba-Rusinov
regime. The intricate magnetic field dependence of the Andreev levels, through
both the Zeeman and Little-Parks effects, may result in robust zero-bias peaks—features
that could be easily misinterpreted as originating from Majorana zero modes but
are unrelated to topological superconductivity.

text: "In the worldwide endeavor for disruptive quantum technologies, germanium
is emerging as a versatile material to realize devices capable of encoding, processing,
or transmitting quantum information. These devices leverage special properties
of the germanium valence-band states, commonly known as holes, such as their inherently
strong spin-orbit coupling and the ability to host superconducting pairing correlations.
In this Review, we initially introduce the physics of holes in low-dimensional
germanium structures with key insights from a theoretical perspective. We then
examine the material science progress underpinning germanium-based planar heterostructures
and nanowires. We review the most significant experimental results demonstrating
key building blocks for quantum technology, such as an electrically driven universal
quantum gate set with spin qubits in quantum dots and superconductor-semiconductor
devices for hybrid quantum systems. We conclude by identifying the most promising
prospects\r\ntoward scalable quantum information processing. "

text: "For automata, synchronization, the problem of bringing an automaton to a
particular state regardless of its initial state, is important. It has several
applications in practice and is related to a fifty-year-old conjecture on the
length of the shortest synchronizing word. Although using shorter words increases
the effectiveness in practice, finding a shortest one (which is not necessarily
unique) is NP-hard. For this reason, there exist various heuristics in the literature.
However, high-quality heuristics such as SynchroP producing relatively shorter
sequences are very expensive and can take hours when the automaton has tens of
thousands of states. The SynchroP heuristic has been frequently used as a benchmark
to evaluate the performance of the new heuristics. In this work, we first improve
the runtime of SynchroP and its variants by using algorithmic techniques. We then
focus on adapting SynchroP for many-core architectures,\r\nand overall, we obtain
more than 1000× speedup on GPUs compared to naive sequential implementation that
has been frequently used as a benchmark to evaluate new heuristics in the literature.
We also propose two SynchroP variants and evaluate their performance."

We would like to thank the authors of (Roman & Szykula, 2015) for providing their
heuristics implementations, which we used to compare our SynchroP implementation
as given in Table 11.

text: The recent outbreak of coronavirus disease 2019 (COVID‐19), caused by the
Severe Acute Respiratory Syndrome Coronavirus‐2 (SARS‐CoV‐2) has resulted in a
world‐wide pandemic. Disseminated lung injury with the development of acute respiratory
distress syndrome (ARDS) is the main cause of mortality in COVID‐19. Although
liver failure does not seem to occur in the absence of pre‐existing liver disease,
hepatic involvement in COVID‐19 may correlate with overall disease severity and
serve as a prognostic factor for the development of ARDS. The spectrum of liver
injury in COVID‐19 may range from direct infection by SARS‐CoV‐2, indirect involvement
by systemic inflammation, hypoxic changes, iatrogenic causes such as drugs and
ventilation to exacerbation of underlying liver disease. This concise review discusses
the potential pathophysiological mechanisms for SARS‐CoV‐2 hepatic tropism as
well as acute and possibly long‐term liver injury in COVID‐19.

text: Domestication is a human‐induced selection process that imprints the genomes
of domesticated populations over a short evolutionary time scale and that occurs
in a given demographic context. Reconstructing historical gene flow, effective
population size changes and their timing is therefore of fundamental interest
to understand how plant demography and human selection jointly shape genomic divergence
during domestication. Yet, the comparison under a single statistical framework
of independent domestication histories across different crop species has been
little evaluated so far. Thus, it is unclear whether domestication leads to convergent
demographic changes that similarly affect crop genomes. To address this question,
we used existing and new transcriptome data on three crop species of Solanaceae
(eggplant, pepper and tomato), together with their close wild relatives. We fitted
twelve demographic models of increasing complexity on the unfolded joint allele
frequency spectrum for each wild/crop pair, and we found evidence for both shared
and species‐specific demographic processes between species. A convergent history
of domestication with gene flow was inferred for all three species, along with
evidence of strong reduction in the effective population size during the cultivation
stage of tomato and pepper. The absence of any reduction in size of the crop in
eggplant stands out from the classical view of the domestication process; as does
the existence of a “protracted period” of management before cultivation. Our results
also suggest divergent management strategies of modern cultivars among species
as their current demography substantially differs. Finally, the timing of domestication
is species‐specific and supported by the few historical records available.

text: "Auxin is a major plant growth regulator, but current models on auxin perception
and signaling cannot explain the whole plethora of auxin effects, in particular
those associated with rapid responses. A possible candidate for a component of
additional auxin perception mechanisms is the AUXIN BINDING PROTEIN 1 (ABP1),
whose function in planta remains unclear.\r\nHere we combined expression analysis
with gain- and loss-of-function approaches to analyze the role of ABP1 in plant
development. ABP1 shows a broad expression largely overlapping with, but not regulated
by, transcriptional auxin response activity. Furthermore, ABP1 activity is not
essential for the transcriptional auxin signaling. Genetic in planta analysis
revealed that abp1 loss-of-function mutants show largely normal development with
minor defects in bolting. On the other hand, ABP1 gain-of-function alleles show
a broad range of growth and developmental defects, including root and hypocotyl
growth and bending, lateral root and leaf development, bolting, as well as response
to heat stress. At the cellular level, ABP1 gain-of-function leads to impaired
auxin effect on PIN polar distribution and affects BFA-sensitive PIN intracellular
aggregation.\r\nThe gain-of-function analysis suggests a broad, but still mechanistically
unclear involvement of ABP1 in plant development, possibly masked in abp1 loss-of-function
mutants by a functional redundancy."

text: "In this thesis, we consider several of the most classical and fundamental
problems in static analysis and formal verification, including invariant generation,
reachability analysis, termination analysis of probabilistic programs, data-flow
analysis, quantitative analysis of Markov chains and Markov decision processes,
and the problem of data packing in cache management.\r\nWe use techniques from
parameterized complexity theory, polyhedral geometry, and real algebraic geometry
to significantly improve the state-of-the-art, in terms of both scalability and
completeness guarantees, for the mentioned problems. In some cases, our results
are the first theoretical improvements for the respective problems in two or three
decades."
