text: 'In this second paper on our variability survey of central stars of planetary
nebulae (CSPNe) using the Zwicky Transient Facility (ZTF), we report 11 long-timescale
variables with variability timescales ranging from months to years. We also present
preliminary analyses based on spectroscopic and/or photometric follow-up observations
for six of them. Among them is NGC 6833, which shows a 980 days periodic variability
with strange characteristics: “triangle-shaped” brightening in r, i, and WISE
bands but almost coincidental shallow dips in the g-band. The most plausible explanation
is a wide binary with the photometric period being the orbital period. Long-period
near-sinusoidal variability was detected in two other systems, NGC 6905 and Kn
26, with periods of 700 days and 230 days, respectively, making them additional
wide-binary candidates. The latter also shows a short period at 1.18 hr. We then
present CTSS 2 and K 3-5, which show brightening and significant reddening over
the whole ZTF baseline. A stellar model fit to the optical spectrum of CTSS 2
reveals it to be one of the youngest post-AGB CSPNe known. Both show high-density
emission-line cores. We propose these to be late-thermal-pulse candidates, currently
evolving towards the AGB phase. We then present recent HST/COS ultraviolet spectroscopy
of the known wide-binary candidate LoTr 1, showing that the hot star is a spectroscopic
twin of the extremely hot white dwarf in UCAC2 46706450. Similar to this object,
LoTr 1 also has a fast rotating wide subgiant companion. We suggest that the long
photometric period of 11 yr is the binary orbital period. Finally, we briefly
discuss the ZTF light curves of the remaining variables, namely Tan 2, K 3-20,
WHTZ 3, Kn J1857+3931, and IPHAS J1927+0814. With these examples, we present the
effectiveness of the von Neumann statistics and Pearson Skew-based metric space
in searching for long-timescale variables.'

text: "Context. This paper investigates the star formation histories (SFHs) of a
sample of massive galaxies (M⋆ ≥ 1010 M⊙) in the redshift range 1 < z < 4.5.\r\nMethods.
We analyzed spectro-photometric data, combining broadband photometry from HST
and JWST with low-resolution grism spectroscopy from JWST/NIRISS, obtained as
part of the MIRI Deep Imaging Survey program. SFHs were derived through spectral
energy distribution fitting using two independent codes, BAGPIPES and synthesizer,
under various SFH assumptions. This approach enables a comprehensive assessment
of the biases introduced by different modeling choices.\r\nResults. The inclusion
of NIRISS spectroscopy, even with its low resolution, significantly improves constraints
on key physical parameters, such as the mass-weighted stellar age (tM) and formation
redshift (zform), by narrowing their posterior distributions. The massive galaxies
in our sample exhibit rapid stellar mass assembly, forming 50% of their mass between
3 ≤ z ≤ 9. The highest inferred formation redshifts are compatible with elevated
star formation efficiencies (ϵ) at early epochs. Nonparametric SFHs generally
imply an earlier and slower mass assembly compared to parametric forms, highlighting
the sensitivity of inferred formation timescales to the chosen SFH model–particularly
for galaxies at z < 2. We find that quiescent galaxies are, on average, older
(tM ∼ 1.1 Gyr) and assembled more rapidly at earlier times than their star-forming
counterparts. These findings support the “downsizing” scenario, in which more
massive and passive systems form earlier and more efficiently."

text: In this paper we derive estimates for the Hessian of the logarithm (log-Hessian)
for solutions to the heat equation. For initial data in the form of log-Lipschitz
perturbation of strongly log-concave measures, the log-Hessian admits an explicit,
uniform (in space) lower bound. This yields a new estimate for the Lipschitz constant
of a transport map pushing forward the standard Gaussian to a measure in this
class. On the other hand, we show that assuming only fast decay of the tails of
the initial datum does not suffice to guarantee uniform log-Hessian upper bounds.

text: "Filtering-based probabilistic numerical solvers for ordinary differential
equations (ODEs), also known as ODE filters, have been established as efficient
methods for quantifying numerical uncertainty in the solution of ODEs. In practical
applications, however, the underlying dynamical system often contains uncertain
parameters, requiring the propagation of this model uncertainty to the ODE solution.
In this paper, we demonstrate that ODE filters, despite their probabilistic nature,
do not automatically solve this uncertainty propagation problem. To address this
limitation, we present a novel approach that combines ODE filters with numerical
quadrature to properly marginalize over uncertain parameters, while accounting
for both parameter uncertainty and numerical solver uncertainty. Experiments across
multiple dynamical systems demonstrate that the resulting uncertainty estimates
closely match reference solutions. Notably, we show\r\nhow the numerical uncertainty
from the ODE solver can help prevent overconfidence in the propagated uncertainty
estimates, especially when using larger step sizes. Our results illustrate that
probabilistic numerical methods can effectively quantify both numerical and parametric
uncertainty in dynamical systems. "

text: “Quasi-solid-state” conversion mechanisms using sparingly solvating electrolytes
(SPSEs) bridge the gap between traditional solid–liquid–solid and solid-state
sulfur conversion in lithium–sulfur (Li–S) batteries. Although these terms are
commonly used, their precise distinctions and impacts on key performance metrics,
such as rate capability, energy density, and capacity fading, remain poorly understood.
In this work, we employ operando small- and wide-angle X-ray scattering alongside
cryogenic transmission electron microscopy (cryo-TEM) to compare Li–S batteries
in sparingly solvating and solvating ether-based electrolytes. We find that, unlike
solvating electrolytes, SPSEs lead to an extended presence of lithium sulfide
during cycling, coexisting with sulfur at a 50% state of charge and beyond. In
the charged state, solid sulfur is present in its amorphous form inside the carbon
black nanopores. These findings indicate that the limited solubility confines
polysulfides in regions near the carbon surface, where these polysulfides enable
conversion between the coexisting solid discharge and charge product.

text: (Scanning) transmission electron microscopy ((S)TEM) has significantly advanced
materials science but faces challenges in correlating precise atomic structure
information with the functional properties of devices due to its time-intensive
nature. To address this, an analytical workflow is introduced for the holistic
characterization, modelling, and simulation of device heterostructures. This workflow
automates the experimental (S)TEM data analysis, providing an in-depth characterization
of crystallographic information, 3D orientation, elemental composition, and strain
distribution. It reduces a process that typically takes days for a trained human
into an automatic routine solved in minutes. Utilizing a physics-guided artificial
intelligence model, it generates representative descriptions of materials and
samples. The workflow culminates in creating digital twins of systems limited
with at least one axis of translational invariance –3D finite element and atomic
models of millions of atoms–enabling simulations that provide crucial insights
into device behavior in practical applications. Demonstrated with SiGe planar
heterostructures for scalable spin qubits, the workflow links digital twins to
theoretical properties, revealing how atomic structure impacts materials and functional
properties such as spatially-resolved phononic or electronic characteristics,
or (inverse) spin orbit lengths. The versatility of the workflow is demonstrated
through its application to a wide array of materials systems, device configurations,
and sample morphologies.

text: Entry into and exit from cellular quiescence require dynamic adjustments in
nutrient acquisition, yet the mechanisms by which quiescent cells downregulate
amino acid (AA) transport remain poorly understood. Here we show that cells entering
quiescence selectively target plasma membrane-resident amino acid transporters
for endocytosis and lysosomal degradation. This process matches amino acid uptake
with reduced translational demand and promotes survival during extended periods
of quiescence. Mechanistically, we identify the α-arrestin TXNIP as a key regulator
of this metabolic adaptation, since it mediates the endocytosis of the SLC7A5-SLC3A2
(LAT1-4F2hc) AA transporter complex in response to reduced AKT signaling. To promote
transporter ubiquitination, TXNIP interacts with NEDD4L and other HECT-type ubiquitin
ligases. Loss of TXNIP disrupts this regulation, resulting in dysregulated amino
acid uptake, sustained mTORC1 signaling, and ultimately cell death under prolonged
quiescence. The characterization of a novel TXNIP loss-of-function variant in
a patient with a severe metabolic disease further supports its role in nutrient
homeostasis and human health. Together, these findings highlight TXNIP’s central
role in controlling nutrient acquisition and metabolic plasticity with implications
for quiescence biology and diseases.

text: "Markov decision processes (MDPs) are a fundamental model of decision making
which exhibit non-deterministic choice as well as probabilistic uncertainty. Traditionally,
verification assumes exact knowledge of the probabilities that govern the behaviour
of an MDP. However, this assumption often is unrealistic, e.g. when modelling
cyber-physical systems or biological processes. There, we can employ statistical
model checking (SMC) to obtain an estimate of the MDP’s value (e.g. the maximal
probability of reaching a goal state) that is close to the true value with high
confidence (probably approximately correct). Model-based SMC algorithms sample
the MDP and build a model of it by estimating all transition probabilities, essentially
for every transition answering the question: “What are the odds?” However, so
far the statistical methods employed by state-of-the-art SMC verification algorithms
are quite naive or even compromise the correctness guarantees.\r\n\r\nOur first
contribution is to survey, categorize, and analyse statistical methods, identifying
those few that are most efficient and that provide suitable guarantees for the
verification setting. Secondly, we propose improvements that exploit structural
knowledge of the MDP. Both contributions generalize to many types of problem statements
as they are largely independent of the setting. Moreover, our experimental evaluation
shows that they lead to significant gains, reducing the number of samples that
an SMC algorithm has to collect by up to two orders of magnitude."

text: "The realistic simulation of sand, soil, powders, rubble piles, and large
collections of rigid bodies is a common and important problem in the fields of
computer graphics, computational physics, and engineering. Direct simulation of
these individual bodies quickly becomes expensive, so we often approximate the
entire group as a continuum material that can be more easily computed using tools
for solving partial differential equations, like the material point method (MPM).
In this paper, we present a method for automatically extracting continuum material
properties from a collection of rigid\r\nbodies. We use numerical homogenization
with periodic boundary conditions to simulate an effectively infinite number of
rigid bodies in contact. We then record the effective stress-strain relationships
from these simulations and convert them into elastic properties and yield criteria
for the continuum simulations. Our experiments validate existing theoretical models
like the Mohr-Coulomb yield surface by extracting material behaviors from a collection
of spheres in contact. We further generalize these existing models to more exotic
materials derived from diverse and non-convex shapes. We\r\nobserve complicated
jamming behaviors from non-convex grains, and we introduce a new material model
for materials with extremely high levels of internal friction and cohesion. We
simulate these new continuum models using MPM with an improved return mapping
technique. The end result is a complete system for turning an input rigid body
simulation into an efficient continuum simulation with the same effective mechanical
properties."

text: Plants have evolved sophisticated mechanisms to adapt to environmental changes,
with root gravitropism playing a pivotal role in nutrient and water acquisition.
Our study reveals that SnRK2 kinases (SnRK2.2 and SnRK2.3) are critical regulators
of root gravitropism through their direct phosphorylation of the auxin transporter
PIN2 at S259. We demonstrate that SnRK2s-mediated phosphorylation modulates both
the polar localization and transport activity of PIN2. Importantly, SnRK2s function
antagonistically to the AGCVIII kinase PID, which phosphorylates PIN2 at a distinct
site (S258), establishing a regulatory balance essential for adaptive root growth.
Structural modeling and phosphorylation assays further suggest that SnRK2s-mediated
phosphorylation at S259 sterically hinders access of PID to S258, providing a
mechanistic basis for their antagonistic relationship. These findings uncover
a novel regulatory mechanism, by which plants fine-tune root developmental programs
to adapt to environmental stimuli, highlighting the evolutionary significance
of multilayered kinase-mediated regulation in plant adaptation.

text: Describing general quantum many-body dynamics is a challenging task due to
the exponential growth of the Hilbert space with system size. The time-dependent
variational principle (TDVP) provides a powerful tool to tackle this task by projecting
quantum evolution onto a classical dynamical system within a variational manifold.
In classical systems, periodic orbits play a crucial role in understanding the
structure of the phase space and the long-term behavior of the system. However,
finding periodic orbits is generally difficult, and their existence and properties
in generic TDVP dynamics over matrix product states have remained largely unexplored.
In this work, we develop an algorithm to systematically identify and characterize
periodic orbits in TDVP dynamics. Applying our method to the periodically kicked
Ising model, we uncover both stable and unstable periodic orbits. We characterize
the Kolmogorov-Arnold-Moser tori in the vicinity of stable periodic orbits and
track the change of the periodic orbits as we modify the Hamiltonian parameters.
We observe that periodic orbits exist at any value of the coupling constant of
the kicked Ising model between prethermal and fully thermalizing regimes, but
their relevance to quantum dynamics and imprint on quantum eigenstates diminishes
as the system leaves the prethermal regime. Our results demonstrate that periodic
orbits provide valuable insights into the TDVP approximation of quantum many-body
evolution and establish a closer connection between quantum and classical chaos.

text: Polynomial quantified entailments with existentially and universally quantified
variables arise in many problems of verification and program analysis. We present
PolyQEnt which is a tool for solving polynomial quantified entailments in which
variables on both sides of the implication are real valued or unbounded integers.
Our tool provides a unified framework for polynomial quantified entailment problems
that arise in several papers in the literature. Our experimental evaluation over
a wide range of benchmarks shows the applicability of the tool as well as its
benefits as opposed to simply using existing SMT solvers to solve such constraints.

text: Ionized proximity zones around luminous quasars provide a unique laboratory
to characterize the Lyα emission lines from z > 6 galaxies without significant
attenuation from the intergalactic medium (IGM). However, Lyα line measurements
for galaxies within high-redshift quasars’ proximity zones have been rare so far.
Here we present deep spectroscopic observations obtained with the NIRSpec/Micro-Shutter
Assembly (MSA) instrument on the James Webb Space Telescope of galaxies in two
z > 6 quasar fields. We measure the Lyα line fluxes for 50 galaxies at 6 < z <
7 with UV absolute magnitude M UV < −19 (median M UV = −19.97), among which 15
are located near the luminous quasars, i.e., within Δv < 2500 km s−1. We find
that galaxies near the quasars show significant flux blueward of the systemic
Lyα wavelength, and have higher Lyα equivalent width compared to galaxies at similar
redshifts that are not located within the quasars’ environment. Our result indicates
little or no redshift evolution for the Lyα emitter fraction from z ∼ 6.4 to z
∼ 5. Leveraging the low IGM opacity in the quasars’ vicinity, we evaluate the
Lyα escape fraction (f esc Ly α) of high-redshift galaxies. Our analysis suggests
that galaxies at 〈z〉 ≈ 6.4 have an average f esc Ly α = 0.14 ± 0.04. This value
is consistent with reionization models where the Lyman continuum escape fraction
is low ( fescLyC ≲ 0.1 ) for luminous galaxies, and where the most luminous galaxies
have only a minor contribution to the total ionizing photon budget. © 2025. The

text: "The origin of merging binary black holes detected through gravitational waves
remains a fundamental question in astrophysics. While stellar evolution imposes
an upper mass limit of ∼50\U0001D440⊙ for black holes, some observed mergers—most
notably GW190521—involve significantly more massive components, suggesting alternative
formation channels. Here we investigate the maximum masses attainable by black
hole mergers within active galactic nucleus (AGN) disks. Using a comprehensive
semianalytic model incorporating 27 binary and environmental parameters, we explore
the role of AGN disk conditions in shaping the upper end of the black hole mass
spectrum. We find that an AGN disk lifetime is the dominant factor, with high-mass
mergers (≳200\U0001D440⊙) only possible if disks persist for ≳40 Myr. The joint
electromagnetic observation of an AGN-assisted merger could therefore lead to
a direct measurement of the age of an AGN disk."

text: The medial axis of a smoothly embedded surface in R^3 consists of all points
for which the Euclidean distance function on the surface has at least two global
minima. We generalize this notion to the mid-sphere axis, which consists of all
points for which the Euclidean distance function has two interchanging saddles
that swap their partners in the pairing by persistent homology. It offers a discrete-algebraic
multi-scale approach to computing ridge-like structures on the surface. As a proof
of concept, an algorithm that computes stair-case approximations of the mid-sphere
axis is provided.

text: "Metabotropic GABA (GABAB) receptors have modulatory functions on neuronal
excitability and\r\nneurotransmitter release. To fulfil these functions, GABAB
receptors form macromolecular signaling complexes with G proteins, effectors,
and other associated proteins. Here we investigated the postnatal development
of GABAB receptors (GABAB1 and GABAB2 subunits) in mouse brain, focusing on potential
similarities in the spatial and temporal expression pattern\r\nof their associated
proteins CaV2.1, Gαo, Gβ5, and RGS7, using histoblots, immunofluorescence, and
immunoelectron microscopic techniques. At all ages analyzed, histoblot showed
that the six proteins were widely expressed in the brain, with mostly an\r\noverlapping
pattern throughout postnatal development. In the hippocampus, immunoelectron microscopy
and quantitative analysis of immunoparticles for GABAB1, GABAB2, Gαo, Gβ5, and
RGS7 revealed their progressive enrichment around excitatory synapses on dendritic
spines of CA1 pyramidal cells toward P15. At presynaptic sites, GABAB receptors
colocalize with\r\nCaV2.1, Gαo, Gβ5, and RGS7 in the active zone and extrasynaptic
membranes of axon terminals, establishing synapses on dendritic spines of CA1
pyramidal cells. In the cerebellum, double immunofluorescence at P7 and P10 revealed
the colocalization of GABAB1 and CaV2.1\r\nin the whole dendritic tree of developing
Purkinje cells. Immunoelectron microscopy at P15 showed that GABAB1, GABAB2, CaV2.1,
Gαo, Gβ5, and RGS7 are distributed along the dendritic surface of Purkinje cells,
enriched close to excitatory synapses in spines.\r\nAltogether, these data suggest
that macromolecular complexes composed of GABAB1 /GABAB2/CaV2.1/ Gαo/Gβ5/RGS7
are pre-assembled during key stages of postnatal development in hippocampal and
cerebellar neurons."

text: "We used observations from the JWST Emission Line Survey (JELS) to measure
the half-light radii (re) of 23 Hα-emitting starforming (SF) galaxies at z = 6.1
in the PRIMER/COSMOS field. Galaxy sizes were measured in JWST near-infrared camera
observations in rest-frame Hα (tracing recent star formation) with the F466N and
F470N narrow-band filters from JELS, and\r\ncompared against rest-R- and V -band
(tracing established stellar populations) and near-ultraviolet sizes. We find
a size–stellar mass(re − M∗) relationship with a slope that is consistent with
literature values at lower redshifts, though offset to lowersizes. We observe
a large scatter in re at low stellar mass (M∗ < 10^8.4 Mo) which we believe is
the result of bursty star formation histories (SFHs) of SF galaxies at the Epoch
of Reionization (EoR). We find that the stellar and ionized gas components are
similar in size at z = 6.1. The evidence of already-established stellar components
in these Hα emitters (HAEs) indicates previous episodes of star formation have
occurred. As such, following other JELS studies finding our HAEs are undergoing
a current burst of star formation, we believe our results indicate that SF galaxies
at the end of the EoR have already experienced a bursty SFH. From our re − M∗
relationship, we find re,F444W = 0.76 ± 0.46 kpc for fixed stellar mass M∗ = 10^9.25
M, which is in agreement with other observations and simulations of SF galaxies
in the literature. We find a close-pair (major) merger fraction of (fmaj. merger
=0.44 ± 0.22) fmerger = 0.43 ± 0.11 for galaxy separations d <~ 25 kpc, which
is in agreement with other z ≈ 6 studies."

text: "We analyse James Webb Space Telescope (JWST) Near Infrared Imager and Slitless
Spectrograph (NIRISS) and Near Infrared Spectrograph (NIRSpec) spectroscopic observations
in the Abell 2744 galaxy cluster field. From approximately 120 candidates, we
identify 12 objects with at least two prominent emission lines among [O II] λ3727,
H β λ4861, [O III] λ4959, [O III] λ5007, and H α λ6563 that are spectroscopically
confirmed by both instruments. Our key findings reveal systematic differences
between the two spectrographs based on source morphology and shutter aperture
placement. Compact objects show comparable or higher\r\nintegrated flux in NIRSpec
relative to NIRISS (within 1σ uncertainties), while extended sources consistently
display higher flux in NIRISS measurements. This pattern reflects NIRSpec’s optimal
coverage for compact objects while potentially undersampling extended sources.
Quantitative analysis demonstrates that NIRSpec recovers at least 63 per cent
of NIRISS-measured flux when the slit covers >15 per cent of the source or when
Re < 1 kpc. For lower coverage or larger effective radii, the recovered flux varies
from 24 per cent to 63 per cent. When studying the H α λ6563/[O III] λ5007 emission
line ratio, we observe that\r\nmeasurements from these different spectrographs
can vary by up to ∼0.3 dex, with significant implications for metallicity and
star formation rate characterizations for individual galaxies. These results highlight
the importance of considering instrumental effects when combining multi-instrument
spectroscopic data and demonstrate that source morphology critically influences
flux\r\nrecovery between slit-based and slitless spectroscopic modes in JWST observations."

text: Gravitropism, the patterning of postembryonic growth in relation to the gravity
vector, allows plants to optimize the use of limited and nonhomogenous resources
in their immediate environment. Since the current model of root gravitropism has
not been able to integrate all aspects of the response (perception, response,
and behavior), research on gravitropism has been dominated by different theories
attempting to conceptualize each aspect individually. In this work, we sought
to reevaluate all the main components of the root graviresponse through the lens
of angle dependence. We show angle dependence in Cholodny–Went-based auxin asymmetry
and growth response, which we tracked back to angle-dependent variation in PIN
asymmetry and statolith sedimentation in the columella. Thanks to this approach,
we were able to suggest distinct roles for PINs and columella cell tiers, and
a potential function for auxin vertical flux through the columella. Our findings
provide a unifying framework to further explore the mechanisms that regulate angle-dependent
gravitropic response, with major implications of time-dependent features of root
graviresponse.

text: Conference travel contributes to the climate footprint of academic research.
Here, we provide a quantitative estimate of the carbon emissions associated with
conference attendance by analyzing travel data from participants of 10 international
conferences in the field of magnetic resonance, namely EUROMAR, ENC and ICMRBS.
We find that attending a EUROMAR conference produces, on average, more than 1 t CO2 eq..
For the analyzed conferences outside Europe, the corresponding value is about
2–3 times higher, on average, with intercontinental trips amounting to up to 5 t.
We compare these conference-related emissions to other activities associated with
research and show that conference travel is a substantial portion of the total
climate footprint of a researcher in magnetic resonance. We explore several strategies
to reduce these emissions, including the impact of selecting conference venues
more strategically and the possibility of decentralized conferences. Through a
detailed comparison of train versus air travel – accounting for both direct and
infrastructure-related emissions – we demonstrate that train travel offers considerable
carbon savings. These data may provide a basis for strategic choices of future
conferences in the field and for individuals deciding on their conference attendance.
