text: The onset of turbulence in pipe flow has defied detailed understanding ever
since the first observations of the spatially heterogeneous nature of the transition.
Recent theoretical studies and experiments in simpler, shear-driven flows suggest
that the onset of turbulence is a directed-percolation non-equilibrium phase transition,
but whether these findings are generic and also apply to open or pressure-driven
flows is unknown. In pipe flow, the extremely long time scales near the transition
make direct observations of critical behaviour virtually impossible. Here we find
a technical solution to that limitation and show that the universality class of
the transition is directed percolation, from which a jammed phase of puffs emerges
above the critical point. Our method is to experimentally characterize all pairwise
interactions between localized patches of turbulence puffs and use these interactions
as input for renormalization group and computer simulations of minimal models
that extrapolate to long length and time scales. The strong interactions in the
jamming regime enable us to explicitly measure the turbulent fraction and confirm
model predictions. Our work shows that directed-percolation scaling applies beyond
simple closed shear flows and underscores how statistical mechanics can lead to
profound, quantitative and predictive insights on turbulent flows and their phases.

text: Contraction and flow of the actin cell cortex have emerged as a common principle
by which cells reorganize their cytoplasm and take shape. However, how these cortical
flows interact with adjacent cytoplasmic components, changing their form and localization,
and how this affects cytoplasmic organization and cell shape remains unclear.
Here we show that in ascidian oocytes, the cooperative activities of cortical
actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive
oocyte cytoplasmic reorganization and shape changes following fertilization. We
show that vegetal-directed cortical actomyosin flows, established upon oocyte
fertilization, lead to both the accumulation of cortical actin at the vegetal
pole of the zygote and compression and local buckling of the adjacent elastic
solid-like myoplasm layer due to friction forces generated at their interface.
Once cortical flows have ceased, the multiple myoplasm buckles resolve into one
larger buckle, which again drives the formation of the contraction pole—a protuberance
of the zygote’s vegetal pole where maternal mRNAs accumulate. Thus, our findings
reveal a mechanism where cortical actomyosin network flows determine cytoplasmic
reorganization and cell shape by deforming adjacent cytoplasmic components through
friction forces.

text: Metazoan development relies on the formation and remodeling of cell-cell contacts.
Dynamic reorganization of adhesion receptors and the actomyosin cell cortex in
space and time plays a central role in cell-cell contact formation and maturation.
Nevertheless, how this process is mechanistically achieved when new contacts are
formed remains unclear. Here, by building a biomimetic assay composed of progenitor
cells adhering to supported lipid bilayers functionalized with E-cadherin ectodomains,
we show that cortical F-actin flows, driven by the depletion of myosin-2 at the
cell contact center, mediate the dynamic reorganization of adhesion receptors
and cell cortex at the contact. E-cadherin-dependent downregulation of the small
GTPase RhoA at the forming contact leads to both a depletion of myosin-2 and a
decrease of F-actin at the contact center. At the contact rim, in contrast, myosin-2
becomes enriched by the retraction of bleb-like protrusions, resulting in a cortical
tension gradient from the contact rim to its center. This tension gradient, in
turn, triggers centrifugal F-actin flows, leading to further accumulation of F-actin
at the contact rim and the progressive redistribution of E-cadherin from the contact
center to the rim. Eventually, this combination of actomyosin downregulation and
flows at the contact determines the characteristic molecular organization, with
E-cadherin and F-actin accumulating at the contact rim, where they are needed
to mechanically link the contractile cortices of the adhering cells.

text: Embryogenesis results from the coordinated activities of different signaling
pathways controlling cell fate specification and morphogenesis. In vertebrate
gastrulation, both Nodal and BMP signaling play key roles in germ layer specification
and morphogenesis, yet their interplay to coordinate embryo patterning with morphogenesis
is still insufficiently understood. Here, we took a reductionist approach using
zebrafish embryonic explants to study the coordination of Nodal and BMP signaling
for embryo patterning and morphogenesis. We show that Nodal signaling triggers
explant elongation by inducing mesendodermal progenitors but also suppressing
BMP signaling activity at the site of mesendoderm induction. Consistent with this,
ectopic BMP signaling in the mesendoderm blocks cell alignment and oriented mesendoderm
intercalations, key processes during explant elongation. Translating these ex
vivo observations to the intact embryo showed that, similar to explants, Nodal
signaling suppresses the effect of BMP signaling on cell intercalations in the
dorsal domain, thus allowing robust embryonic axis elongation. These findings
suggest a dual function of Nodal signaling in embryonic axis elongation by both
inducing mesendoderm and suppressing BMP effects in the dorsal portion of the
mesendoderm.

text: Tropical precipitation extremes and their changes with surface warming are
investigated using global storm resolving simulations and high-resolution observations.
The simulations demonstrate that the mesoscale organization of convection, a process
that cannot be physically represented by conventional global climate models, is
important for the variations of tropical daily accumulated precipitation extremes.
In both the simulations and observations, daily precipitation extremes increase
in a more organized state, in association with larger, but less frequent, storms.
Repeating the simulations for a warmer climate results in a robust increase in
monthly-mean daily precipitation extremes. Higher precipitation percentiles have
a greater sensitivity to convective organization, which is predicted to increase
with warming. Without changes in organization, the strongest daily precipitation
extremes over the tropical oceans increase at a rate close to Clausius-Clapeyron
(CC) scaling. Thus, in a future warmer state with increased organization, the
strongest daily precipitation extremes over oceans increase at a faster rate than
CC scaling.

text: Wildfire intensity and severity have been increasing in the Iberian Peninsula
in recent years, particularly in the Galicia region, due to rising temperatures
and accumulating drier combustible vegetation in unmanaged lands. This leads to
substantial emissions of air pollutants, notably fine particles (PM2.5), posing
a risk to public health. This study aims to assess the impact of local and regional
wildfires on PM2.5 levels in Galicia's main cities and their implications for
air quality and public health. Over a decade (2013–2022), PM2.5 data during wildfire
seasons were analyzed using statistical methods and Lagrangian tracking to monitor
smoke plume evolution. The results reveal a notable increase in PM2.5 concentration
during the wildfire season (June–November) in Galicia, surpassing health guidelines
during extreme events and posing a significant health risk to the population.
Regional wildfire analyses indicate that smoke plumes from Northern Portugal contribute
to pollution in Galician cities, influencing the seasonality of heightened PM2.5
levels. During extensive wildfires, elevated PM2.5 concentration values persisted
for several days, potentially exacerbating health concerns in Galicia. These findings
underscore the urgency of implementing air pollution prevention and management
measures in the region, including developing effective alerts for large-scale
events and improved wildfire management strategies to mitigate their impact on
air quality in Galician cities.

text: 'The Mediterranean region is experiencing pronounced aridification and in
certain areas higher occurrence of intense precipitation. In this work, we analyze
the evolution of the precipitation probability distribution in terms of precipitating
days (or “wet-days”) and all-days quantile trends, in Europe and the Mediterranean,
using the ERA5 reanalysis. Looking at the form of wet-days quantile trends curves,
we identify four regimes. Two are predominant: in most of northern Europe the
precipitation quantiles all intensify, while in the Mediterranean the low-medium
quantiles are mostly decreasing as extremes intensify or decrease. The wet-days
distribution is then modeled by a Weibull law with two parameters, whose changes
capture the four regimes. Assessing the significance of the parameters'' changes
over 1950–2020 shows that a signal on wet-days distribution has already emerged
in northern Europe (where the distribution shifts to more intense precipitation),
but not yet in the Mediterranean, where the natural variability is stronger. We
extend the results by describing the all-days distribution change as the wet-days’
change plus a contribution from the dry-days frequency change, and study their
relative contribution. In northern Europe, the wet-days distribution change is
the dominant driver, and the contribution of dry-days frequency change can be
neglected for wet-days percentiles above about 50%. In the Mediterranean, however,
the change of precipitation distribution comes from the significant increase of
dry-days frequency instead of an intensity change during wet-days. Therefore,
in the Mediterranean the increase of dry-days frequency is crucial for all-days
trends, even for heavy precipitation.'

text: BMP signaling has a conserved function in patterning the dorsal-ventral body
axis in Bilateria and the directive axis in anthozoan cnidarians. So far, cnidarian
studies have focused on the role of different BMP signaling network components
in regulating pSMAD1/5 gradient formation. Much less is known about the target
genes downstream of BMP signaling. To address this, we generated a genome-wide
list of direct pSMAD1/5 target genes in the anthozoan Nematostella
vectensis, several of which were conserved in Drosophila
and Xenopus. Our ChIP-seq analysis revealed that many
of the regulatory molecules with documented bilaterally symmetric expression in
Nematostella are directly controlled by BMP signaling.
We identified several so far uncharacterized BMP-dependent transcription factors
and signaling molecules, whose bilaterally symmetric expression may be indicative
of their involvement in secondary axis patterning. One of these molecules is zswim4-6,
which encodes a novel nuclear protein that can modulate the pSMAD1/5 gradient
and potentially promote BMP-dependent gene repression.

text: Global storm-resolving models (GSRMs) use strongly refined horizontal grids
compared with the climate models typically used in the Coupled Model Intercomparison
Project (CMIP) but employ comparable vertical grid spacings. Here, we study how
changes in the vertical grid spacing and adjustments to the integration time step
affect the basic climate quantities simulated by the ICON-Sapphire atmospheric
GSRM. Simulations are performed over a 45 d period for five different vertical
grids with between 55 and 540 vertical layers and maximum tropospheric vertical
grid spacings of between 800 and 50 m, respectively. The effects of changes in
the vertical grid spacing are compared with the effects of reducing the horizontal
grid spacing from 5 to 2.5 km. For most of the quantities considered, halving
the vertical grid spacing has a smaller effect than halving the horizontal grid
spacing, but it is not negligible. Each halving of the vertical grid spacing,
along with the necessary reductions in time step length, increases cloud liquid
water by about 7 %, compared with an approximate 16 % decrease for halving the
horizontal grid spacing. The effect is due to both the vertical grid refinement
and the time step reduction. There is no tendency toward convergence in the range
of grid spacings tested here. The cloud ice amount also increases with a refinement
in the vertical grid, but it is hardly affected by the time step length and does
show a tendency to converge. While the effect on shortwave radiation is globally
dominated by the altered reflection due to the change in the cloud liquid water
content, the effect on longwave radiation is more difficult to interpret because
changes in the cloud ice concentration and cloud fraction are anticorrelated in
some regions. The simulations show that using a maximum tropospheric vertical
grid spacing larger than 400 m would increase the truncation error strongly. Computing
time investments in a further vertical grid refinement can affect the truncation
errors of GSRMs similarly to comparable investments in horizontal refinement,
because halving the vertical grid spacing is generally cheaper than halving the
horizontal grid spacing. However, convergence of boundary layer cloud properties
cannot be expected, even for the smallest maximum tropospheric grid spacing of
50 m used in this study.

text: The elimination of rain evaporation in the planetary boundary layer (PBL)
has been found to lead to convective self‐aggregation (CSA) even without radiative
feedback, but the precise mechanisms underlying this phenomenon remain unclear.
We conducted cloud‐resolving simulations with two domain sizes and progressively
reduced rain evaporation in the PBL. Surprisingly, CSA only occurred when rain
evaporation was almost completely removed. The additional convective heating resulting
from the reduction of evaporative cooling in the moist patch was found to be the
trigger, thereafter a dry subsidence intrusion into the PBL in the dry patch takes
over and sets CSA in motion. Temperature and moisture anomalies oppose each other
in their buoyancy effects, hence explaining the need for almost total rain evaporation
removal. We also found radiative cooling and not cold pools to be the leading
cause for the comparative ease of CSA to take place in the larger domain.

text: Current knowledge suggests a drought Indian monsoon (perhaps a severe one)
when the El Nino Southern Oscillation and Pacific Decadal Oscillation each exhibit
positive phases (a joint positive phase). For the monsoons, which are exceptions
in this regard, we found northeast India often gets excess pre-monsoon rainfall.
Further investigation reveals that this excess pre-monsoon rainfall is produced
by the interaction of the large-scale circulation associated with the joint phase
with the mountains in northeast India. We posit that a warmer troposphere, a consequence
of excess rainfall over northeast India, drives a stronger monsoon circulation
and enhances monsoon rainfall over central India. Hence, we argue that pre-monsoon
rainfall over northeast India can be used for seasonal monsoon rainfall prediction
over central India. Most importantly, its predictive value is at its peak when
the Pacific Ocean exhibits a joint positive phase and the threat of extreme drought
monsoon looms over India.

text: This study investigates the response of Indian summer monsoon (ISM) precipitation
to CO2 removal, with a specific focus on regional and subseasonal variations.
Following CO2 removal, monsoon circulation weakens throughout the summer owing
to the reduced large-scale meridional temperature gradient around India. Weakened
monsoon circulation decreases the local-scale thermodynamic stability within India,
following monsoon-onset periods. While the frequency of synoptic-scale ISM low-pressure
systems (LPSs) decreases overall, the lower thermodynamic stability causes the
LPSs to form and resultantly shift west and south from their typical paths, last
longer and move more quickly zonally during August and September. Changes in these
rain-producing processes induce distinct regional (Western Ghats, south-central-east
India, and Tamil Nadu) and subseasonal precipitation responses. Also, extreme
precipitation exhibits similar patterns, but is more strongly affected by changes
in LPS. Our results suggest that reliable future projections of regional hydroclimate
change require a more accurate understanding of multi-scale precipitation processes.

to reproduce the results of the manuscript \"The Unreasonable Efficiency of Total
Rain Evaporation Removal in Triggering Convective Self-Aggregation\" submitted
to the Geophysical Research Letters (GRL).\r\n\r\nBrief description of project:
This project aims to examine the impact of rain evaporation removal or reduction
in the planetary boundary layer (PBL) on convective self aggregation (CSA). Non-rotating
radiative-convective equilibrium (RCE) simulations were conducted with the System
for Atmospheric Modeling (SAM) cloud resolving model. Rain evaporation in the
lowest 1 km was progressively reduced and the effect on CSA was investigated.
The physical processes underlying this type of aggregation (referred to in the
manuscript as no-evaporation CSA, or NE-CSA) were analyzed and described. \r\nThe

text: "The behavior of a rigid body primarily depends on its mass moments, which
consist of the mass, center of mass, and moments of inertia. It is possible to
manipulate these quantities without altering the geometric appearance of an object
by introducing cavities in its interior. Algorithms that find cavities of suitable
shapes and sizes have enabled the computational design of spinning tops, yo-yos,
wheels, buoys, and statically balanced objects. Previous work is based, for example,
on topology optimization on voxel grids, which introduces a large number of optimization
variables and box constraints, or offset surface computation, which cannot guarantee
that solutions to a feasible problem will always be found.\r\n\r\nIn this work,
we provide a mathematical analysis of constrained topology optimization problems
that depend only on mass moments. This class of problems covers, among others,
all applications mentioned above. Our main result is to show that no matter the
outer shape of the rigid body to be optimized or the optimization objective and
constraints considered, the optimal solution always features a quadric-shaped
interface between material and cavities. This proves that optimal interfaces are
always ellipsoids, hyperboloids, paraboloids, or one of a few degenerate cases,
such as planes.\r\n\r\nThis insight lets us replace a difficult topology optimization
problem with a provably equivalent non-linear equation system in a small number
(<10) of variables, which represent the coefficients of the quadric. This system
can be solved in a few seconds for most examples, provides insights into the geometric
structure of many specific applications, and lets us describe their solution properties.
Finally, our method integrates seamlessly into modern fabrication workflows because
our solutions are analytical surfaces that are native to the CAD domain."

text: Our goal is to investigate fundamental properties of the system of internally
cooled convection. The system consists of an upward thermal flux at the lower
boundary, a mean temperature lapse-rate and a constant cooling term in the bulk
with the bulk cooling in thermal equilibrium with the input heat flux. This simple
model represents idealised dry convection in the atmospheric boundary layer, where
the cooling mimics the radiative cooling to space notably through longwave radiation.
We perform linear stability analysis of the model for different values of the
mean stratification to derive the critical forcing above which the fluid is convectively
unstable to small perturbations. The dynamic behavior of the fluid system is described
and the scaling of various important measured quantities such as the total vertical
convective heat flux and the upward mass flux is measured. We introduce a lapse-rate
dependent dimensionless Rayleigh-number Ray that determines the behavior of the
system, finding that the convective heat-flux and mass-flux scale approximately
as Ray0.5 and Ray0.7 respectively. The area-fraction of the domain that is occupied
by upward and downward moving fluid and the skewness of the vertical velocity
are studied to understand the asymmetry inherent in the system. We conclude with
a short discussion on the relevance to atmospheric convection and the scope for
further investigations of atmospheric convection using similar simplified approaches.

text: "We present PeFLL, a new personalized federated learning algorithm that improves\r\nover
the state-of-the-art in three aspects: 1) it produces more accurate models,\r\nespecially
in the low-data regime, and not only for clients present during its\r\ntraining
phase, but also for any that may emerge in the future; 2) it reduces the\r\namount
of on-client computation and client-server communication by providing\r\nfuture
clients with ready-to-use personalized models that require no additional\r\nfinetuning
or optimization; 3) it comes with theoretical guarantees that establish\r\ngeneralization
from the observed clients to future ones.\r\nAt the core of PeFLL lies a learning-to-learn
approach that jointly trains an\r\nembedding network and a hypernetwork. The embedding
network is used to\r\nrepresent clients in a latent descriptor space in a way
that reflects their similarity\r\nto each other. The hypernetwork takes as input
such descriptors and outputs the\r\nparameters of fully personalized client models.
In combination, both networks\r\nconstitute a learning algorithm that achieves
state-of-the-art performance in several\r\npersonalized federated learning benchmarks"

text: In practice, training using federated learning can be orders of magnitude
slower than standard centralized training. This severely limits the amount of
experimentation and tuning that can be done, making it challenging to obtain good
performance on a given task. Server-side proxy data can be used to run training
simulations, for instance for hyperparameter tuning. This can greatly speed up
the training pipeline by reducing the number of tuning runs to be performed overall
on the true clients. However, it is challenging to ensure that these simulations
accurately reflect the dynamics of the real federated training. In particular,
the proxy data used for simulations often comes as a single centralized dataset
without a partition into distinct clients, and partitioning this data in a naive
way can lead to simulations that poorly reflect real federated training. In this
paper we address the challenge of how to partition centralized data in a way that
reflects the statistical heterogeneity of the true federated clients. We propose
a fully federated, theoretically justified, algorithm that efficiently learns
the distribution of the true clients and observe improved server-side simulations
when using the inferred distribution to create simulated clients from the centralized
