text: 'We introduce LRT-NG, a set of techniques and an associated toolset that computes
a reachtube (an over-approximation of the set of reachable states over a given
time horizon) of a nonlinear dynamical system. LRT-NG significantly advances the
state-of-the-art Langrangian Reachability and its associated tool LRT. From a
theoretical perspective, LRT-NG is superior to LRT in three ways. First, it uses
for the first time an analytically computed metric for the propagated ball which
is proven to minimize the ball’s volume. We emphasize that the metric computation
is the centerpiece of all bloating-based techniques. Secondly, it computes the
next reachset as the intersection of two balls: one based on the Cartesian metric
and the other on the new metric. While the two metrics were previously considered
opposing approaches, their joint use considerably tightens the reachtubes. Thirdly,
it avoids the "wrapping effect" associated with the validated integration of the
center of the reachset, by optimally absorbing the interval approximation in the
radius of the next ball. From a tool-development perspective, LRT-NG is superior
to LRT in two ways. First, it is a standalone tool that no longer relies on CAPD.
This required the implementation of the Lohner method and a Runge-Kutta time-propagation
method. Secondly, it has an improved interface, allowing the input model and initial
conditions to be provided as external input files. Our experiments on a comprehensive
set of benchmarks, including two Neural ODEs, demonstrates LRT-NG’s superior performance
compared to LRT, CAPD, and Flow*.'

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: 'Inversions are chromosomal rearrangements where the order of genes is reversed.
Inversions originate by mutation and can be under positive, negative or balancing
selection. Selective effects result from potential disruptive effects on meiosis,
gene disruption at inversion breakpoints and, importantly, the effects of inversions
as modifiers of recombination rate: Recombination is strongly reduced in individuals
heterozygous for an inversion, allowing for alleles at different loci to be inherited
as a ‘block’. This may lead to a selective advantage whenever it is favourable
to keep certain combinations of alleles associated, for example under local adaptation
with gene flow. Inversions can cover a considerable part of a chromosome and contain
numerous loci under different selection pressures, so that the resulting overall
effects may be complex. Empirical data from various systems show that inversions
may have a prominent role in local adaptation, speciation, parallel evolution,
the maintenance of polymorphism and sex chromosome evolution.'

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: We investigate the role of a warm sea surface temperature (SST) anomaly (hot
spot of typically 3 to 5 K) on the aggregation of convection using cloud-resolving
simulations in a nonrotating framework. It is well known that SST gradients can
spatially organize convection. Even with uniform SST, the spontaneous self-aggregation
of convection is possible above a critical SST (here 295 K), arising mainly from
radiative feedbacks. We investigate how a circular hot spot helps organize convection,
and how self-aggregation feedbacks modulate this organization. The hot spot significantly
accelerates aggregation, particularly for warmer/larger hot spots, and extends
the range of SSTs for which aggregation occurs; however, at cold SST (290 K) the
aggregated cluster disaggregates if we remove the hot spot. A large convective
instability over the hot spot leads to stronger convection and generates a large-scale
circulation which forces the subsidence drying outside the hot spot. Indeed, convection
over the hot spot brings the atmosphere toward a warmer temperature. The warmer
temperatures are imprinted over the whole domain by gravity waves and subsidence
warming. The initial transient warming and concomitant subsidence drying suppress
convection outside the hot spot, thus driving the aggregation. The hot-spot-induced
large-scale circulation can enforce the aggregation even without radiative feedbacks
for hot spots sufficiently large/warm. The strength of the large-scale circulation,
which defines the speed of aggregation, is a function of the hot spot fractional
area. At equilibrium, once the aggregation is well established, the moist convective
region with upward midtropospheric motion, centered over the hot spot, has an
area surprisingly independent of the hot spot size.

text: We see them in our everyday lives. They make skies and sunsets even more beautiful,
inspiring painters all over the world. But what are clouds? What are the physical
processes occurring within a cloud? Do they all look alike, or are there different
types of clouds? Why? Beyond our small human scale, how are clouds distributed
at large, planetary scales? How do they couple and interact with the large-scale
circulation of the atmosphere? What do the physics of cloud formation tell us
about the hydrological cycle, including mean and extreme precipitation, in our
current climate and in a warming world? What role do they play in the global energetics
of the planet, for instance by reflecting the incoming shortwave radiation from
the Sun, and by reducing the outgoing longwave radiation to space, because of
their high altitudes and thus cold temperatures? These are the questions that
will be addressed in these five lectures.

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.

combination of weighted versions of the volume, area, mean curvature, and Gaussian

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
are discussed.

text: In order to provide a local description of a regular function in a small neighbourhood
of a point x, it is sufficient by Taylor’s theorem to know the value of the function
as well as all of its derivatives up to the required order at the point x itself.
In other words, one could say that a regular function is locally modelled by the
set of polynomials. The theory of regularity structures due to Hairer generalizes
this observation and provides an abstract setup, which in the application to singular
SPDE extends the set of polynomials by functionals constructed from, e.g., white
noise. In this context, the notion of Taylor polynomials is lifted to the notion
of so-called modelled distributions. The celebrated reconstruction theorem, which
in turn was inspired by Gubinelli’s \textit {sewing lemma}, is of paramount importance
for the theory. It enables one to reconstruct a modelled distribution as a true
distribution on Rd which is locally approximated by this extended set of models
or “monomials”. In the original work of Hairer, the error is measured by means
of Hölder norms. This was then generalized to the whole scale of Besov spaces
by Hairer and Labbé. It is the aim of this work to adapt the analytic part of
the theory of regularity structures to the scale of Triebel–Lizorkin spaces.
