text: "Despite the advances in probabilistic model checking, the scalability of
the verification methods remains limited. In particular, the state space often
becomes extremely large when instantiating parameterized Markov decision processes
(MDPs) even with moderate values. Synthesizing policies for such huge MDPs is
beyond the reach of available tools. We propose a learning-based approach to obtain
a reasonable policy for such huge MDPs.\r\n\r\nThe idea is to generalize optimal
policies obtained by model-checking small instances to larger ones using decision-tree
learning. Consequently, our method bypasses the need for explicit state-space
exploration of large models, providing a practical solution to the state-space
explosion problem. We demonstrate the efficacy of our approach by performing extensive
experimentation on the relevant models from the quantitative verification benchmark
set. The experimental results indicate that our policies perform well, even when
the size of the model is orders of magnitude beyond the reach of state-of-the-art
analysis tools."

text: Recent advances in the field of bottom-up synthetic biology have led to the
development of synthetic cells that mimic some features of real cells, such as
division, protein synthesis, or DNA replication. Larger assemblies of synthetic
cells may be used to form prototissues. However, existing prototissues are limited
by their relatively small lateral dimensions or their lack of remodeling ability.
Here, we introduce a lipid-based tissue mimetic that can be easily prepared and
functionalized, consisting of a millimeter-sized “lipid-foam” with individual
micrometer-sized compartments bound by lipid bilayers. We characterize the structural
and mechanical properties of the lipid-foam tissue mimetic, and we demonstrate
self-healing capabilities enabled by the fluidity of the lipid bilayers. Upon
inclusion of bacteria in the tissue compartments, we observe that the tissue mimetic
exhibits network-wide tension fluctuations driven by membrane tension generation
by the swimming bacteria. Active tension fluctuations facilitate the fluidization
and reorganization of the prototissue, providing a versatile platform for understanding
and mimicking biological tissues.

text: We study the BCS critical temperature on half-spaces in dimensions d =1, 2,
3 with Dirichlet or Neumann boundary conditions. We prove that the critical temperature
on a half-space is strictly higher than on Rd, at least at weak coupling in d
= 1, 2 and weak coupling and small chemical potential in d = 3. Furthermore, we
show that the relative shift in critical temperature vanishes in the weak coupling
limit.

text: Cell migration is a fundamental process during embryonic development. Most
studies in vivo have focused on the migration of cells using the extracellular
matrix (ECM) as their substrate for migration. In contrast, much less is known
about how cells migrate on other cells, as found in early embryos when the ECM
has not yet formed. Here, we show that lateral mesendoderm (LME) cells in the
early zebrafish gastrula use the ectoderm as their substrate for migration. We
show that the lateral ectoderm is permissive for the animal-pole-directed migration
of LME cells, while the ectoderm at the animal pole halts it. These differences
in permissiveness depend on the lateral ectoderm being more cohesive than the
animal ectoderm, a property controlled by bone morphogenetic protein (BMP) signaling
within the ectoderm. Collectively, these findings identify ectoderm tissue cohesion
as one critical factor in regulating LME migration during zebrafish gastrulation.

text: "In the third APOKASC catalog, we present data for the complete sample of
15,808 evolved stars with APOGEE spectroscopic parameters and Kepler asteroseismology.
We used 10 independent asteroseismic analysis techniques and anchor our system
on fundamental radii derived from Gaia L and spectroscopic Teff. We provide evolutionary
state, asteroseismic surface gravity, mass, radius, age, and the data used to
derive them for 12,418 stars. This includes 10,036 exceptionally precise measurements,
with median fractional uncertainties in \r\nvmax, Δν, mass, radius, and age of
0.6%, 0.6%, 3.8%, 1.8%, and 11.1%, respectively. We provide more limited data
for 1624 additional stars that either have lower-quality data or are outside of
our primary calibration domain. Using lower red giant branch (RGB) stars, we find
a median age for the chemical thick disk of 9.14 ± 0.05(ran) ± 0.9(sys) Gyr with
an age dispersion of 1.1 Gyr, consistent with our error model. We calibrate our
red clump (RC) mass loss to derive an age consistent with the lower RGB and provide
asymptotic GB and RGB ages for luminous stars. We also find a sharp upper-age
boundary in the chemical thin disk. We find that scaling relations are precise
and accurate on the lower RGB and RC, but they become more model dependent for
more luminous giants and break down at the tip of the RGB. We recommend the use
of multiple methods, calibration to a fundamental scale, and the use of stellar
models to interpret frequency spacings."

text: "Polyploidization is a common occurrence in the evolutionary history of flowering
plants, significantly contributing to their adaptability and diversity. However,
the molecular mechanisms behind these adaptive advantages are not well understood.\r\nThrough
comprehensive phenotyping of diploid and tetraploid clones from Citrus and Poncirus
genera, we discovered that genome doubling significantly enhances salt stress
resilience. Epigenetic and transcriptomic analyses revealed that increased ethylene
production in the roots of tetraploid plants was associated with hypomethylation
and enhanced chromatin accessibility of the ACO1 gene. This increased ethylene
production activates the transcription of reactive oxygen species scavenging genes
and stress-related hormone biosynthesis genes. Consequently, tetraploid plants
exhibited superior root functionality under salt stress, maintaining improved
cytosolic K+/Na+ homeostasis.\r\nTo genetically validate the link between salt
stress resilience and ACO1 expression, we generated overexpression and knockout
lines, confirming the central role of ACO1 expression regulation following genome
doubling in salt stress resilience.\r\nOur work elucidates the molecular mechanisms
underlying the role of genome doubling in stress resilience. We also highlight
the importance of chromatin dynamics in fine-tuning ethylene gene expression and
activating salt stress resilience pathways, offering valuable insights into plant
adaptation and crop genome evolution."

text: 'Recently, Biagioli and Tompkins (2023, https://doi.org/10.1029/2022ms003231)
used a simple stochastic model to derive a dimensionless parameter to predict
convective self aggregation (SA) development, which was based on the derivation
of the maximum free convective distance ($d_{clr}$) expected in the pre-aggregated,
random state. Our goal is to test and further investigate this hypothesis, namely
that $d_{clr}$ can predict SA occurrence, using an ensemble of twenty-four distinct
combinations of horizontal mixing, planetary boundary layer (PBL), and microphysical
parameterizations. We conclude that the key impact of parameterization schemes
on SA is through their control of the number of convective cores and their relative
spacing, $d_{clr}$, which itself is impacted by cold-pool (CP) properties and
mean updraft core size. SA is more likely when the convective core count is small,
while CPs modify convective spacing via suppression in their interiors and triggering
by gust-front convergence and collisions. Each parameterization scheme emphasizes
a different mechanism. Subgrid-scale horizontal turbulent mixing mainly affects
SA through the determination of convective core size and thus spacing. The sensitivity
to the microphysics is mainly through rain evaporation and the subsequent impact
on CPs, while perturbations to the ice cloud microphysics have a limited effect.
Non-local PBL mixing schemes promote SA primarily by increasing convective inhibition
through inversion entrainment and altering low cloud amounts, leading to fewer
convective cores and larger $d_{clr}$. '

text: The size-Ramsey number r^(H) of a graph H is the smallest number of edges
a (host) graph G can have, such that for any red/blue colouring of G, there is
a monochromatic copy of H in G. Recently, Conlon, Nenadov and Trujić showed that
if H is a graph on n vertices and maximum degree three, then r^(H)=O(n8/5), improving
upon the upper bound of n5/3+o(1) by Kohayakawa, Rödl, Schacht and Szemerédi.
In this paper we show that r^(H)≤n3/2+o(1). While the previously used host graphs
were vanilla binomial random graphs, we prove our result using a novel host graph
construction. Our bound hits a natural barrier of the existing methods.

text: Auxin and its PIN-FORMED (PIN) exporters are essential for tissue repair and
regeneration in flowering plants. To gain insight into the evolution of this mechanism,
we investigated their roles in leaves excised from Physcomitrium patens, a bryophyte
known for its remarkable cell reprogramming capacity. We used various approaches
to manipulate auxin levels, including exogenous application, pharmacological manipulations,
and auxin biosynthesis mutants. We observed no significant effect on the rate
of cell reprogramming. Rather, our analysis of auxin dynamics revealed a decrease
in auxin levels upon excision, which was followed by a local increase before the
reprogramming process began. Mutant analysis revealed that PpPINs are required
for effective cell reprogramming, and endogenously expressed PpPINA-GFP accumulates
polarly at sites that will develop into future filamentous stem cells. In addition,
hyperpolarized PpPINA variants carrying mutated phosphorylation sites showed a
marked delay in reprogramming, whereas endogenous or nonpolar versions do not
have this effect. These results underscore that both the levels and the polarity
of PpPINA are important for efficient cell reprogramming. Overall, these findings
highlight the pivotal role of PIN polarity in plant regeneration. Furthermore,
they suggest that understanding polarity mechanisms could have broader implications
for improving regenerative processes across various plant species.

text: Nitrogen (N) is an essential macronutrient for plant development and, ultimately,
yield. Identifying the genetic components and mechanisms underlying N use efficiency
in maize (Zea mays L.) is thus of great importance. Nitrate (NO3−) is the preferred
inorganic N source in maize. Here we performed a genome-wide association study
of shoot NO3− accumulation in maize seedlings grown under low-NO3− conditions,
identifying the ferredoxin family gene ZmFd4 as a major contributor to this trait.
ZmFd4 interacts and co-localizes with nitrite reductases (ZmNiRs) in chloroplasts
to promote their enzymatic activity. Furthermore, ZmFd4 forms a high-affinity
heterodimer with its closest paralogue, ZmFd9, in a NO3−-sensitive manner. Although
ZmFd4 exerts similar biochemical functions as ZmFd9, ZmFd4 and ZmFd9 interaction
limits their ability to associate with ZmNiRs and stimulate their activity. Knockout
lines for ZmFd4 with decreased NO3− contents exhibit more efficient NO3− assimilation,
and field experiments show consistently improved N utilization and grain yield
under N-deficient conditions. Our work thus provides molecular and mechanistic
insights into the natural variation in N utilization, instrumental for genetic
improvement of yield in maize and, potentially, in other crops.

text: "Auxin, indole-3-acetic acid (IAA), is a key phytohormone with diverse morphogenic
roles in land plants, but its function and transport mechanisms in algae remain
poorly understood. We therefore aimed to explore the role of IAA in a complex,
streptophyte algae Chara braunii.\r\nHere, we described novel responses of C.
braunii to IAA and characterized two homologs of PIN auxin efflux carriers: CbPINa
and CbPINc. We determined their localization in C. braunii using epitope-specific
antibodies and tested their function in heterologous land plant models. Further,
using phosphoproteomic analysis, we identified IAA-induced phosphorylation events.\r\nThe
thallus regeneration assay showed that IAA promotes thallus elongation and side
branch development. Immunolocalization of CbPINa and CbPINc confirmed their presence
on the plasma membrane of vegetative and generative cells of C. braunii. However,
functional assays in tobacco BY-2 cells demonstrated that CbPINa affects auxin
transport, whereas CbPINc does not. The IAA is effective in the acceleration of
cytoplasmic streaming and the phosphorylation of evolutionary conserved targets
such as homolog of RAF-like kinase.\r\nThese findings suggest that, although canonical
PIN-mediated auxin transport mechanisms might not be fully conserved in Chara,
IAA is involved in morphogenesis and fast signaling processes."

text: An ordered r-matching is an r-uniform hypergraph matching equipped with an
ordering on its vertices. These objects can be viewed as natural generalisations
of r-dimensional orders. The theory of ordered 2-matchings is well developed and
has connections and applications to extremal and enumerative combinatorics, probability
and geometry. On the other hand, in the case r≥3 much less is known, largely
due to a lack of powerful bijective tools. Recently, Dudek, Grytczuk and Ruciński
made some first steps towards a general theory of ordered r-matchings, and in
this paper we substantially improve several of their results and introduce some
new directions of study. Many intriguing open questions remain.

text: Dynamic DNA methylation represses transposable elements (TEs) and regulates
gene activity, playing a pivotal role in plant development. Although substantial
progress has been made in understanding DNA methylation reprogramming during germline
development in Arabidopsis thaliana, whether similar mechanisms exist in other
dicot plants remains unclear. Here, we analyzed DNA methylation levels in meiocytes,
microspores, and pollens of Brassica Rapa using whole-genome bisulfite sequencing
(WGBS). Global DNA methylation analysis revealed similar CHH methylation reprogramming
compared to Arabidopsis, while distinct patterns were observed in the dynamics
of global CG and CHG methylation in B. rapa. Differentially methylated region
(DMR) analysis identified specifically methylated loci in the male sex cells of
B. Rapa with a stronger tendency to target genes, similar to observations in Arabidopsis.
Additionally, we found that the activity and genomic targeting preference of the
small RNA-directed DNA methylation (RdDM) were altered during B. Rapa male germline
development. A subset of long terminal repeat (LTR) TEs were activated, possibly
due to the dynamic regulation of DNA methylation during male sexual development
in B. Rapa. These findings provided new insights into the evolution of epigenetic
reprogramming mechanisms in plants.

text: We demonstrate the formation of ferroelectric domain-wall polarons in a minimal
two-dimensional lattice model of electrons interacting with rotating dipoles.
Along the domain wall, the rotors polarize in opposite directions, causing the
electron to localize along a particular lattice direction. The rotor-electron
coupling is identified as the origin of a structural instability in the crystal
that leads to the domain-wall formation via a symmetry-breaking process. Our results
provide the first theoretical description of ferroelectric polarons, as discussed
in the context of soft semiconductors.

text: "Polymorphic short insertions and deletions (INDELs \r\n 50 bp) are abundant,
although less common than single nucleotide polymorphisms (SNPs). Evidence from
model organisms shows INDELs to be more strongly influenced by purifying selection
than SNPs. Partly for this reason, INDELs are rarely used as markers for demographic
processes or to detect divergent selection. Here, we compared INDELs and SNPs
in the intertidal snail Littorina saxatilis, focussing on hybrid zones between
ecotypes, in order to test the utility of INDELs in the detection of divergent
selection. We computed INDEL and SNP site frequency spectra using capture sequencing
data. We assessed the impact of divergent selection by analyzing allele frequency
clines across habitat boundaries. We also examined the influence of GC-biased
gene conversion because it may be confounded with signatures of selection. We
show evidence that short INDELs are affected more by purifying selection than
SNPs, but part of the observed site frequency spectra difference can be attributed
to GC-biased gene conversion. We did not find a difference in the impact of divergent
selection between short INDELs and SNPs. Short INDELs and SNPs were similarly
distributed across the genome and so are likely to respond to indirect selection
in the same way. A few regions likely affected by divergent selection were revealed
by INDELs and not by SNPs. Short INDELs can be useful (additional) genetic markers
helping to identify genomic regions important for adaptation and population divergence."

text: "White dwarfs (WDs) are the most abundant compact objects, and recent surveys
have suggested that over a third of WDs in accreting binaries host a strong (B
\ ≳ 1 MG) magnetic field. However, the origin and evolution of WD magnetism remain
under debate. Two WD pulsars, AR Sco and J191213.72–441045.1 (J1912), have been
found, which are non-accreting binaries hosting rapidly spinning (1.97 minutes
and 5.30 minutes, respectively) magnetic WDs. The WD in AR Sco is slowing down
on a (math formular) yr timescale. It is believed they will eventually become
polars, accreting systems in which a magnetic WD (B ≈ 10−240 MG) accretes from
a Roche lobe-filling donor spinning in sync with the orbit (≳78 minutes). Here,
we present multiwavelength data and analysis of Gaia22ayj, which outbursted in
2022 March. We find that Gaia22ayj is a magnetic accreting WD that is rapidly
spinning down (math formular\r\n yr) like WD pulsars, but shows clear evidence
of accretion, like polars. Strong linear polarization (40%) is detected in Gaia22ayj;
such high levels have only been seen in the WD pulsar AR Sco and demonstrate the
WD is magnetic. High speed photometry reveals a 9.36 minutes period accompanying
a high amplitude (∼2 mag) modulation. We associate this with a WD spin or spin–orbit
beat period, not an orbital period as was previously suggested. Fast (60 s) optical
spectroscopy reveals a broad \"hump,\" reminiscent of cyclotron emission in polars,
between 4000 and 8000 Å. We find an X-ray luminosity of (math formular) in the
0.3–8 keV energy range, while two very large array radio campaigns resulted in
a non-detection with a Fr < 15.8 μJy 3σ upper limit. The shared properties of
both WD pulsars and polars suggest that Gaia22ayj is a missing link between the
two classes of magnetic WD binaries."

text: Let μ(G) denote the minimum number of edges whose addition to G results in
a Hamiltonian graph, and let μ^(G) denote the minimum number of edges whose addition
to G results in a pancyclic graph. We study the distributions of μ(G),μ^(G) in
the context of binomial random graphs. Letting d=d(n):=n⋅p, we prove that there
exists a function f:R+→[0,1] of order f(d)=12de−d+e−d+O(d6e−3d) such that, if
G∼G(n,p) with 20≤d(n)≤0.4logn, then with high probability μ(G)=(1+o(1))⋅f(d)⋅n.
Let ni(G) denote the number of degree i vertices in G. A trivial lower bound on
μ(G) is given by the expression n0(G)+⌈12n1(G)⌉. In the denser regime of random
graphs, we show that if np−13logn−2loglogn→∞ and G∼G(n,p) then, with high probability,
μ(G)=n0(G)+⌈12n1(G)⌉. For completion to pancyclicity, we show that if G∼G(n,p)
and np≥20 then, with high probability, μ^(G)=μ(G). Finally, we present a polynomial
time algorithm such that, if G∼G(n,p) and np≥20, then, with high probability,
the algorithm returns a set of edges of size μ(G) whose addition to G results
in a pancyclic (and therefore also Hamiltonian) graph.

This leads to unconventional behavior and collective dynamics, such as self-organization
into complex structures. Characterizing the nonequilibrium interactions of microswimmers
is crucial for advancing our understanding of active systems. However, this remains
a challenge owing to the importance of fluctuations at the microscale and the
difficulty in disentangling the different contributions to the interactions. Here,
we show a massive dependence of the nonequilibrium interactions on the shape of
catalytic microswimmers. We perform tracking experiments at high throughput to
map interactions between nanocolloidal tracers and dimeric microswimmers of various
aspect ratios. Our method leverages dual tracers with differing phoretic mobilities
to quantitatively disentangle phoretic motion from hydrodynamic advection. This
approach is validated through experiments on single chemically active sites and
on immobilized catalytic microswimmers. We further investigate the activity-driven
interactions of free microswimmers and directly measure their phoretic interactions.
When compared to standard models, our findings highlight the important role of
osmotic flows for microswimmers near surfaces and reveal an enhanced contribution
of hydrodynamic advection relative to phoretic motion as the size of the microswimmer
increases. Our study provides robust measurements of the nonequilibrium interactions
from catalytic microswimmers and lays the groundwork for a realistic description
of active systems.

text: "1. Climate change is expected to induce shifts in the composition, structure
and functioning of Arctic tundra ecosystems. Increases in the frequency and severity
of tundra fires have the potential to catalyse vegetation transitions with far-reaching
local, regional and global consequences.\r\n2. We propose that post-fire tundra
recovery, coupled with climate change, may not necessarily lead to pre-fire conditions.
Our hypothesis, based on surveys and literature, suggests two climate–fire driven
trajectories. One trajectory results in increased woody vegetation under low fire
frequency; the other results in grass dominance under high frequency.\r\n3. Future
research should address uncertainties regarding possible tundra ecosystem shifts
linked to fires, using methods that encompass greater temporal and spatial scales
than previously addressed. More case studies, especially in underrepresented regions
and ecosystem types, are essential to broaden the empirical basis for forecasts
and potential fire management strategies.\r\n4. Synthesis. Our review synthesises
current knowledge on post-fire vegetation trajectories in Arctic tundra ecosystems,
highlighting potential transitions and alternative ecosystem states and their
implications. We discuss challenges in defining and predicting these trajectories
as well as future directions."

text: In cryo-electron microscopy, accurate particle localization and classification
are imperative. Recent deep learning solutions, though successful, require extensive
training datasets. The protracted generation time of physics-based models, often
employed to produce these datasets, limits their broad applicability. We introduce
FakET, a method based on neural style transfer, capable of simulating the forward
operator of any cryo transmission electron microscope. It can be used to adapt
a synthetic training dataset according to reference data producing high-quality
simulated micrographs or tilt-series. To assess the quality of our generated data,
we used it to train a state-of-the-art localization and classification architecture
and compared its performance with a counterpart trained on benchmark data. Remarkably,
our technique matches the performance, boosts data generation speed 750x, uses
33x less memory, and scales well to typical transmission electron microscope detector
sizes. It leverages GPU acceleration and parallel processing. The source code
is available at https://github.com/paloha/faket/.
