text: The leaf is a crucial organ evolved with remarkable morphological diversity
to maximize plant photosynthesis. The leaf shape is a key trait that affects photosynthesis,
flowering rates, disease resistance, and yield. Although many genes regulating
leaf development have been identified in the past years, the precise regulatory
architecture underlying the generation of diverse leaf shapes remains to be elucidated.
We used cotton as a reference model to probe the genetic framework underlying
divergent leaf forms. Comparative transcriptome analysis revealed that the GhARF16‐1
and GhKNOX2‐1 genes might be potential regulators of leaf shape. We functionally
characterized the auxin‐responsive factor ARF16‐1 acting upstream of GhKNOX2‐1
to determine leaf morphology in cotton. The transcription of GhARF16‐1 was significantly
higher in lobed‐leaved cotton than in smooth‐leaved cotton. Furthermore, the overexpression
of GhARF16‐1 led to the upregulation of GhKNOX2‐1 and resulted in more and deeper
serrations in cotton leaves, similar to the leaf shape of cotton plants overexpressing
GhKNOX2‐1. We found that GhARF16‐1 specifically bound to the promoter of GhKNOX2‐1
to induce its expression. The heterologous expression of GhARF16‐1 and GhKNOX2‐1
in Arabidopsis led to lobed and curly leaves, and a genetic analysis revealed
that GhKNOX2‐1 is epistatic to GhARF16‐1 in Arabidopsis, suggesting that the GhARF16‐1
and GhKNOX2‐1 interaction paradigm also functions to regulate leaf shape in Arabidopsis.
To our knowledge, our results uncover a novel mechanism by which auxin, through
the key component ARF16‐1 and its downstream‐activated gene KNOX2‐1, determines
leaf morphology in eudicots.

text: To adapt to the diverse array of biotic and abiotic cues, plants have evolved
sophisticated mechanisms to sense changes in environmental conditions and modulate
their growth. Growth-promoting hormones and defence signalling fine tune plant
development antagonistically. During host-pathogen interactions, this defence-growth
trade-off is mediated by the counteractive effects of the defence hormone salicylic
acid (SA) and the growth hormone auxin. Here we revealed an underlying mechanism
of SA regulating auxin signalling by constraining the plasma membrane dynamics
of PIN2 auxin efflux transporter in Arabidopsis thaliana roots. The lateral diffusion
of PIN2 proteins is constrained by SA signalling, during which PIN2 proteins are
condensed into hyperclusters depending on REM1.2-mediated nanodomain compartmentalisation.
Furthermore, membrane nanodomain compartmentalisation by SA or Remorin (REM) assembly
significantly suppressed clathrin-mediated endocytosis. Consequently, SA-induced
heterogeneous surface condensation disrupted asymmetric auxin distribution and
the resultant gravitropic response. Our results demonstrated a defence-growth
trade-off mechanism by which SA signalling crosstalked with auxin transport by
concentrating membrane-resident PIN2 into heterogeneous compartments.

text: In RuCl3, inelastic neutron scattering and Raman spectroscopy reveal a continuum
of non-spin-wave excitations that persists to high temperature, suggesting the
presence of a spin liquid state on a honeycomb lattice. In the context of the
Kitaev model, finite magnetic fields introduce interactions between the elementary
excitations, and thus the effects of high magnetic fields that are comparable
to the spin-exchange energy scale must be explored. Here, we report measurements
of the magnetotropic coefficient—the thermodynamic coefficient associated with
magnetic anisotropy—over a wide range of magnetic fields and temperatures. We
find that magnetic field and temperature compete to determine the magnetic response
in a way that is independent of the large intrinsic exchange-interaction energy.
This emergent scale-invariant magnetic anisotropy provides evidence for a high
degree of exchange frustration that favours the formation of a spin liquid state
in RuCl3.

text: 'This paper continues the discussion started in [CK19] concerning Arnold''s
legacy on classical KAM theory and (some of) its modern developments. We prove
a detailed and explicit `global'' Arnold''s KAM Theorem, which yields, in particular,
the Whitney conjugacy of a non{degenerate, real{analytic, nearly-integrable Hamiltonian
system to an integrable system on a closed, nowhere dense, positive measure subset
of the phase space. Detailed measure estimates on the Kolmogorov''s set are provided
in the case the phase space is: (A) a uniform neighbourhood of an arbitrary (bounded)
set times the d-torus and (B) a domain with C2 boundary times the d-torus. All
constants are explicitly given.'

text: The Mytilus complex of marine mussel species forms a mosaic of hybrid zones,
found across temperate regions of the globe. This allows us to study ‘replicated’
instances of secondary contact between closely related species. Previous work
on this complex has shown that local introgression is both widespread and highly
heterogeneous, and has identified SNPs that are outliers of differentiation between
lineages. Here, we developed an ancestry‐informative panel of such SNPs. We then
compared their frequencies in newly sampled populations, including samples from
within the hybrid zones, and parental populations at different distances from
the contact. Results show that close to the hybrid zones, some outlier loci are
near to fixation for the heterospecific allele, suggesting enhanced local introgression,
or the local sweep of a shared ancestral allele. Conversely, genomic cline analyses,
treating local parental populations as the reference, reveal a globally high concordance
among loci, albeit with a few signals of asymmetric introgression. Enhanced local
introgression at specific loci is consistent with the early transfer of adaptive
variants after contact, possibly including asymmetric bi‐stable variants (Dobzhansky‐Muller
incompatibilities), or haplotypes loaded with fewer deleterious mutations. Having
escaped one barrier, however, these variants can be trapped or delayed at the
next barrier, confining the introgression locally. These results shed light on
the decay of species barriers during phases of contact.

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: '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. "
