text: We consider the free additive convolution of two probability measures μ and
ν on the real line and show that μ ⊞ v is supported on a single interval if μ
and ν each has single interval support. Moreover, the density of μ ⊞ ν is proven
to vanish as a square root near the edges of its support if both μ and ν have
power law behavior with exponents between −1 and 1 near their edges. In particular,
these results show the ubiquity of the conditions in our recent work on optimal
local law at the spectral edges for addition of random matrices [5].

text: "Microwave photonics lends the advantages of fiber optics to electronic sensing
and communication systems. In contrast to nonlinear optics, electro-optic devices
so far require classical modulation fields whose variance is dominated by electronic
or thermal noise rather than quantum fluctuations. Here we demonstrate bidirectional
single-sideband conversion of X band microwave to C band telecom light with a
microwave mode occupancy as low as 0.025 ± 0.005 and an added output noise of
less than or equal to 0.074 photons. This is facilitated by radiative cooling
and a triply resonant ultra-low-loss transducer operating at millikelvin temperatures.
The high bandwidth of 10.7 MHz and total (internal) photon conversion\r\nefficiency
of 0.03% (0.67%) combined with the extremely slow heating rate of 1.1 added output
noise photons per second for the highest available pump power of 1.48 mW puts
near-unity efficiency pulsed quantum transduction within reach. Together with
the non-Gaussian resources of superconducting qubits this might provide the practical
foundation to extend the range and scope of current quantum networks in analogy
to electrical repeaters in classical fiber optic communication."

text: The couplings among clouds, convection, and circulation in trade-wind regimes
remain a fundamental puzzle that limits our ability to constrain future climate
change. Radiative heating plays an important role in these couplings. Here we
calculate the clear-sky radiative profiles from 2001 in-situ soundings (978 dropsondes
and 1023 radiosondes) collected during the EUREC4A field campaign, which took
place south and east of Barbados in January–February 2020. We describe the method
used to calculate these radiative profiles and present preliminary results sampling
variability at multiple scales, from the variability across all soundings to groupings
by diurnal cycle and mesoscale organization state, as well as individual soundings
associated with elevated moisture layers. This clear-sky radiative profiles data
set can provide important missing detail to what can be learned from calculations
based on passive remote sensing and help in investigating the role of radiation
in dynamic and thermodynamic variability in trade-wind regimes. All data are archived
and freely available for public access on AERIS (Albright et al. (2020), https://doi.org/10.25326/78).

text: This study investigates the feedbacks between an interactive sea surface temperature
(SST) and the self‐aggregation of deep convective clouds, using a cloud‐resolving
model in nonrotating radiative‐convective equilibrium. The ocean is modeled as
one layer slab with a temporally fixed mean but spatially varying temperature.
We find that the interactive SST decelerates the aggregation and that the deceleration
is larger with a shallower slab, consistent with earlier studies. The surface
temperature anomaly in dry regions is positive at first, thus opposing the diverging
shallow circulation known to favor self‐aggregation, consistent with the slower
aggregation. But surprisingly, the driest columns then have a negative SST anomaly,
thus strengthening the diverging shallow circulation and favoring aggregation.
This diverging circulation out of dry regions is found to be well correlated with
the aggregation speed. It can be linked to a positive surface pressure anomaly
(PSFC), itself the consequence of SST anomalies and boundary layer radiative cooling.
The latter cools and dries the boundary layer, thus increasing PSFC anomalies
through virtual effects and hydrostasy. Sensitivity experiments confirm the key
role played by boundary layer radiative cooling in determining PSFC anomalies
in dry regions, and thus the shallow diverging circulation and the aggregation
speed.

text: The goal of this study is to understand the mechanisms controlling the isotopic
composition of the water vapor near the surface of tropical oceans, at the scale
of about a hundred kilometers and a month. In the tropics, it has long been observed
that the isotopic compositions of rain and vapor near the surface are more depleted
when the precipitation rate is high. This is called the “amount effect.” Previous
studies, based on observations or models with parameterized convection, have highlighted
the roles of deep convective and mesoscale downdrafts and rain evaporation. But
the relative importance of these processes has never been quantified. We hypothesize
that it can be quantified using an analytical model constrained by large‐eddy
simulations. Results from large‐eddy simulations confirm that the classical amount
effect can be simulated only if precipitation rate changes result from changes
in the large‐scale circulation. We find that the main process depleting the water
vapor compared to the equilibrium with the ocean is the fact that updrafts stem
from areas where the water vapor is more enriched. The main process responsible
for the amount effect is the fact that when the large‐scale ascent increases,
isotopic vertical gradients are steeper, so that updrafts and downdrafts deplete
the subcloud layer more efficiently.

text: Nearly all regions in the world are projected to become dryer in a warming
climate. Here, we investigate the Mediterranean region, often referred to as a
climate change “hot spot”. From regional climate simulations, it is shown that
although enhanced warming and drying over land is projected, the spatial pattern
displays high variability. Indeed, drying is largely caused by enhanced warming
over land. However, in Northern Europe, soil moisture alleviates warming induced
drying by up to 50% due to humidity uptake from land. In already arid regions,
the Mediterranean Sea is generally the only humidity source, and drying is only
due to land warming. However, over Sahara and the Iberian Peninsula, enhanced
warming over land is insufficient to explain the extreme drying. These regions
are also isolated from humidity advection by heat lows, which are cyclonic circulation
anomalies associated with surface heating over land. The cyclonic circulation
scales with the temperature gradient between land and ocean which increases with
climate change, reinforcing the cyclonic circulation over Sahara and the Iberian
Peninsula, both diverting the zonal advection of humidity to the south of the
Iberian Peninsula. The dynamics are therefore key in the warming and drying of
the Mediterranean region, with extreme aridification over the Sahara and Iberian
Peninsula. In these regions, the risk for human health due to the thermal load
which accounts for air temperature and humidity is therefore projected to increase
significantly with climate change at a level of extreme danger.

text: This paper reviews recent important advances in our understanding of the response
of precipitation extremes to warming from theory and from idealized cloud-resolving
simulations. A theoretical scaling for precipitation extremes has been proposed
and refined in the past decades, allowing to address separately the contributions
from the thermodynamics, the dynamics and the microphysics. Theoretical constraints,
as well as remaining uncertainties, associated with each of these three contributions
to precipitation extremes, are discussed. Notably, although to leading order precipitation
extremes seem to follow the thermodynamic theoretical expectation in idealized
simulations, considerable uncertainty remains regarding the response of the dynamics
and of the microphysics to warming, and considerable departure from this theoretical
expectation is found in observations and in more realistic simulations. We also
emphasize key outstanding questions, in particular the response of mesoscale convective
organization to warming. Observations suggest that extreme rainfall often comes
from an organized system in very moist environments. Improved understanding of
the physical processes behind convective organization is needed in order to achieve
accurate extreme rainfall prediction in our current, and in a warming climate.

text: The goal of this study is twofold. First, we aim at developing a simple model
as an interpretative framework for the water vapor isotopic variations in the
tropical troposphere over the ocean. We use large-eddy simulations to justify
the underlying assumptions of this simple model, to constrain its input parameters
and to evaluate its results. Second, we aim at interpreting the depletion of the
water vapor isotopic composition in the lower and mid-troposphere as precipitation
increases, which is a salient feature in tropical oceanic observations. This feature
constitutes a stringent test on the relevance of our interpretative framework.
Previous studies, based on observations or on models with parameterized convection,
have highlighted the roles of deep convective and meso-scale downdrafts, rain
evaporation, rain-vapor diffusive exchanges and mixing processes. The interpretative
framework that we develop is a two-column model representing the net ascent in
clouds and the net descent in the environment. We show that the mechanisms for
depleting the troposphere when precipitation rate increases all stem from the
higher tropospheric relative humidity. First, when the relative humidity is larger,
less snow sublimates before melting and a smaller fraction of rain evaporates.
Both effects lead to more depleted rain evaporation and eventually more depleted
water vapor. This mechanism dominates in regimes of large-scale ascent. Second,
the entrainment of dry air into clouds reduces the vertical isotopic gradient
and limits the depletion of tropospheric water vapor. This mechanism dominates
in regimes of large-scale descent.

text: Representing an atom by a solid sphere in 3-dimensional Euclidean space, we
get the space-filling diagram of a molecule by taking the union. Molecular dynamics
simulates its motion subject to bonds and other forces, including the solvation
free energy. The morphometric approach [12, 17] writes the latter as a linear
combination of weighted versions of the volume, area, mean curvature, and Gaussian
curvature of the space-filling diagram. We give a formula for the derivative of
the weighted mean curvature. Together with the derivatives of the weighted volume
in [7], the weighted area in [3], and the weighted Gaussian curvature [1], this
yields the derivative of the morphometric expression of the solvation free energy.

text: Auxin is a key hormonal regulator, that governs plant growth and development
in concert with other hormonal pathways. The unique feature of auxin is its polar,
cell-to-cell transport that leads to the formation of local auxin maxima and gradients,
which coordinate initiation and patterning of plant organs. The molecular machinery
mediating polar auxin transport is one of the important points of interaction
with other hormones. Multiple hormonal pathways converge at the regulation of
auxin transport and form a regulatory network that integrates various developmental
and environmental inputs to steer plant development. In this review, we discuss
recent advances in understanding the mechanisms that underlie regulation of polar
auxin transport by multiple hormonal pathways. Specifically, we focus on the post-translational
mechanisms that contribute to fine-tuning of the abundance and polarity of auxin
transporters at the plasma membrane and thereby enable rapid modification of the
auxin flow to coordinate plant growth and development.

text: Active navigation relies on effectively extracting information from the surrounding
environment, and often features the tracking of gradients of a relevant signal—such
as the concentration of molecules. Microfluidic networks of closed pathways pose
the challenge of determining the shortest exit pathway, which involves the proper
local decision-making at each bifurcating junction. Here, we focus on the basic
decision faced at a T-junction by a microscopic particle, which orients among
possible paths via its sensing of a diffusible substance's concentration. We study
experimentally the navigation of colloidal particles following concentration gradients
by diffusiophoresis. We treat the situation as a mean first passage time (MFPT)
problem that unveils the important role of a separatrix in the concentration field
to determine the statistics of path taking. Further, we use numerical experiments
to study different strategies, including biomimetic ones such as run and tumble
or Markovian chemotactic migration. The discontinuity in the MFPT at the junction
makes it remarkably difficult for microscopic agents to follow the shortest path,
irrespective of adopted navigation strategy. In contrast, increasing the size
of the sensing agents improves the efficiency of short-path taking by harvesting
information on a larger scale. It inspires the development of a run-and-whirl
dynamics that takes advantage of the mathematical properties of harmonic functions
to emulate particles beyond their own size.

text: Quantum transduction, the process of converting quantum signals from one form
of energy to another, is an important area of quantum science and technology.
The present perspective article reviews quantum transduction between microwave
and optical photons, an area that has recently seen a lot of activity and progress
because of its relevance for connecting superconducting quantum processors over
long distances, among other applications. Our review covers the leading approaches
to achieving such transduction, with an emphasis on those based on atomic ensembles,
opto-electro-mechanics, and electro-optics. We briefly discuss relevant metrics
from the point of view of different applications, as well as challenges for the
future.

text: Quantum information technology based on solid state qubits has created much
interest in converting quantum states from the microwave to the optical domain.
Optical photons, unlike microwave photons, can be transmitted by fiber, making
them suitable for long distance quantum communication. Moreover, the optical domain
offers access to a large set of very well‐developed quantum optical tools, such
as highly efficient single‐photon detectors and long‐lived quantum memories. For
a high fidelity microwave to optical transducer, efficient conversion at single
photon level and low added noise is needed. Currently, the most promising approaches
to build such systems are based on second‐order nonlinear phenomena such as optomechanical
and electro‐optic interactions. Alternative approaches, although not yet as efficient,
include magneto‐optical coupling and schemes based on isolated quantum systems
like atoms, ions, or quantum dots. Herein, the necessary theoretical foundations
for the most important microwave‐to‐optical conversion experiments are provided,
their implementations are described, and the current limitations and future prospects

text: "The optimization of multilayer neural networks typically leads to a solution\r\nwith
zero training error, yet the landscape can exhibit spurious local minima\r\nand
the minima can be disconnected. In this paper, we shed light on this\r\nphenomenon:
we show that the combination of stochastic gradient descent (SGD)\r\nand over-parameterization
makes the landscape of multilayer neural networks\r\napproximately connected and
thus more favorable to optimization. More\r\nspecifically, we prove that SGD solutions
are connected via a piecewise linear\r\npath, and the increase in loss along this
path vanishes as the number of\r\nneurons grows large. This result is a consequence
of the fact that the\r\nparameters found by SGD are increasingly dropout stable
as the network becomes\r\nwider. We show that, if we remove part of the neurons
(and suitably rescale the\r\nremaining ones), the change in loss is independent
of the total number of\r\nneurons, and it depends only on how many neurons are
left. Our results exhibit\r\na mild dependence on the input dimension: they are
dimension-free for two-layer\r\nnetworks and depend linearly on the dimension
for multilayer networks. We\r\nvalidate our theoretical findings with numerical
experiments for different\r\narchitectures and classification tasks."

text: We propose a novel hybridization method for stability analysis that over-approximates
nonlinear dynamical systems by switched systems with linear inclusion dynamics.
We observe that existing hybridization techniques for safety analysis that over-approximate
nonlinear dynamical systems by switched affine inclusion dynamics and provide
fixed approximation error, do not suffice for stability analysis. Hence, we propose
a hybridization method that provides a state-dependent error which converges to
zero as the state tends to the equilibrium point. The crux of our hybridization
computation is an elegant recursive algorithm that uses partial derivatives of
a given function to obtain upper and lower bound matrices for the over-approximating
linear inclusion. We illustrate our method on some examples to demonstrate the
application of the theory for stability analysis. In particular, our method is
able to establish stability of a nonlinear system which does not admit a polynomial
Lyapunov function.

text: "Recent works have shown that gradient descent can find a global minimum for
over-parameterized neural networks where the widths of all the hidden layers scale
polynomially with N (N being the number of training samples). In this paper, we
prove that, for deep networks, a single layer of width N following the input layer
suffices to ensure a similar guarantee. In particular, all the remaining layers
are allowed to have constant widths, and form a pyramidal topology. We show an
application of our result to the widely used LeCun’s initialization and obtain
an over-parameterization requirement for the single wide layer of order N2.\r\n"

text: Rhombic dodecahedron is a space filling polyhedron which represents the close
packing of spheres in 3D space and the Voronoi structures of the face centered
cubic (FCC) lattice. In this paper, we describe a new coordinate system where
every 3-integer coordinates grid point corresponds to a rhombic dodecahedron centroid.
In order to illustrate the interest of the new coordinate system, we propose the
characterization of 3D digital plane with its topological features, such as the
interrelation between the thickness of the digital plane and the separability
constraint we aim to obtain. We also present the characterization of 3D digital
lines and study it as the intersection of multiple digital planes. Characterization
of 3D digital sphere with relevant topological features is proposed as well along
with the 48-symmetry appearing in the new coordinate system.
