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.

text: We theoretically investigate the stationary properties of a spin-1/2 impurity
immersed in a one-dimensional confined Bose gas. In particular, we consider coherently
coupled spin states with an external field, where only one spin component interacts
with the bath, enabling light dressing of the impurity and spin-dependent bath-impurity
interactions. Through detailed comparisons with ab-initio many-body simulations,
we demonstrate that the composite system is accurately described by a simplified
effective Hamiltonian. The latter builds upon previously developed effective potential
approaches in the absence of light dressing. It can be used to extract the impurity
energy, residue, effective mass, and anharmonicity induced by the phononic dressing.
Light-dressing is shown to increase the polaron residue, undressing the impurity
from phononic excitations because of strong spin coupling. For strong repulsions,
previously shown to trigger dynamical Bose polaron decay (a phenomenon called
temporal orthogonality catastrophe), it is explained that strong light-dressing
stabilizes a repulsive polaron-dressed state. Our results establish the effective
Hamiltonian framework as a powerful tool for exploring strongly interacting polaronic
systems and corroborating forthcoming experimental realizations.

text: We explore the problem of mean estimation for a high-dimensional binary symmetric
Gaussian mixture model, where the label (sign) follows a time-inhomogeneous Markov
chain. We propose a spectral estimator based on a partition of a subset of the
samples to blocks. We develop a computationally efficient algorithm to find the
optimal blocks, and derive minimax lower bounds on the estimation loss of any
estimator, which establish the effectiveness of our proposed estimator. The resulting
minimax rate illuminates the interplay between the sample size, dimension, signal
strength, and the memory on the loss.

text: "Quantization is a powerful tool for accelerating large language model (LLM)
inference, but the accuracy-performance trade-offs across different formats remain
unclear. In this paper, we conduct the most comprehensive empirical study to date,
evaluating FP8, INT8, and INT4\r\nquantization across academic benchmarks and
real-world tasks on the entire Llama-3.1 model\r\nfamily. Through over 500,000
evaluations, our investigation yields several key findings: (1) FP8 (W8A8-FP)
is effectively lossless across all model scales, (2) well-tuned INT8 (W8A8-INT)
achieves surprisingly low (1-3%) accuracy degradation, and (3) INT4 weightonly
(W4A16-INT) is more competitive than expected, rivaling 8-bit quantization. Further,
we investigate the optimal quantization format for different deployments by analyzing
inference performance through the popular vLLM framework. Our analysis provides
clear deployment recommendations: W4A16 is the most cost-efficient for synchronous
setups, while W8A8 dominates in asynchronous\r\ncontinuous batching. For mixed
workloads, the optimal choice depends on the specific use\r\ncase. Our findings
offer practical, data-driven guidelines for deploying quantized LLMs at scale—ensuring
the best balance between speed, efficiency, and accuracy. "

text: 'The Next Generation of Earth Modeling Systems (nextGEMS) project aimed to
produce multidecadal climate simulations, for the first time, with resolved kilometer-scale
(km-scale) processes in the ocean, land, and atmosphere. In only 3 years, nextGEMS
achieved this milestone with the two km-scale Earth system models, ICOsahedral
Non-hydrostatic model (ICON) and Integrated Forecasting System coupled to the
Finite-volumE Sea ice-Ocean Model (IFS-FESOM). nextGEMS was based on three cornerstones:
(1) developing km-scale Earth system models with small errors in the energy and
water balance, (2) performing km-scale climate simulations with a throughput greater
than 1 simulated year per day, and (3) facilitating new workflows for an efficient
analysis of the large simulations with common data structures and output variables.
These cornerstones shaped the timeline of nextGEMS, divided into four cycles.
Each cycle marked the release of a new configuration of ICON and IFS-FESOM, which
were evaluated at hackathons. The hackathon participants included experts from
climate science, software engineering, and high-performance computing as well
as users from the energy and agricultural sectors. The continuous efforts over
the four cycles allowed us to produce 30-year simulations with ICON and IFS-FESOM,
spanning the period 2020–2049 under the SSP3-7.0 scenario. The throughput was
about 500 simulated days per day on the Levante supercomputer of the German Climate
Computing Center (DKRZ). The simulations employed a horizontal grid of about 5 km
resolution in the ocean and 10 km resolution in the atmosphere and land. Aside
from this technical achievement, the simulations allowed us to gain new insights
into the realism of ICON and IFS-FESOM. Beyond its time frame, nextGEMS builds
the foundation of the Climate Change Adaptation Digital Twin developed in the
Destination Earth initiative and paves the way for future European research on
climate change.'

text: Emission from two massive black holes (MBHs) bound in a close binary is expected
to be modulated by different processes, such as the Doppler boost due to the orbital
motion, accretion rate variability generated by the interaction with a circumbinary
disc, and binary gravitational self-lensing. When the binary is compact enough,
the two black holes are thought to be surrounded by a common broad-line region
that reprocesses the impinging periodically varying ionising flux, creating broad
emission lines with variable line shapes. Therefore, the study of broad emission
line variability through multi-epoch spectroscopic campaigns is of paramount importance
for the unambiguous identification of a binary. In this work, we study the response
of a disc-like broad-line region to the Doppler-boosted ionising flux emitted
by sub-milliparsec MBH binaries on a circular orbit and compare it with the response
of a broad-line region illuminated by a single MBH with a periodically but isotropically
varying intrinsic luminosity. We show that in the binary case, the time lags of
the blue and red wings of the broad emission lines, arising from diametrically
opposite sides of the circumbinary disc, are out of phase by half of the binary’s
orbital period, as they each respond to the periodic ‘lighthouse’ modulation from
the binary’s continuum emission. This asymmetric time lag represents a new binary
signature that cannot be mimicked by a single MBH.

text: 'We consider two-player zero-sum concurrent stochastic games (CSGs) played
on graphs with reachability and safety objectives. These include degenerate classes
such as Markov decision processes or turn-based stochastic games, which can be
solved by linear or quadratic programming; however, in practice, value iteration
(VI) outperforms the other approaches and is the most implemented method. Similarly,
for CSGs, this practical performance makes VI an attractive alternative to the
standard theoretical solution via the existential theory of reals.VI starts with
an under-approximation of the sought values for each state and iteratively updates
them, traditionally terminating once two consecutive approximations are ϵ-close.
However, this stopping criterion lacks guarantees on the precision of the approximation,
which is the goal of this work. We provide bounded (a.k.a. interval) VI for CSGs:
it complements standard VI with a converging sequence of over-approximations and
terminates once the over- and under-approximations are ϵ-close.'

text: This paper studies the expected value of multiplicative rewards, where rewards
obtained in each step are multiplied (instead of the usual addition), in Markov
chains (MCs) and Markov decision processes (MDPs). One of the key differences
to additive rewards is that the expected value may diverge to ∞ not only due to
recurrent, but also due to transient states.For MCs, computing the value is shown
to be possible in polynomial time given an oracle for the comparison of succinctly
represented integers (CSRI), which is only known to be solvable in polynomial
time subject to number-theoretic conjectures. Interestingly, distinguishing whether
the value is ∞ or 0 is at least as hard as CSRI, while determining if it is one
of these two can be done in polynomial time. In MDPs, the optimal value can be
computed in polynomial space. Further refined complexity results and results on
the complexity of optimal schedulers are presented. The techniques developed for
MDPs additionally allow to solve the multiplicative variant of the stochastic
shortest path problem. Finally, for MCs and MDPs where an absorbing state is reached
almost surely, all considered problems are solvable in polynomial time.

text: 'Cumulative prospect theory (CPT) is the first theory for decision-making
under uncertainty that combines full theoretical soundness and empirically realistic
features [1], [Page 2]. While CPT was originally considered in one-shot settings
for risk-aware decision-making, we consider CPT in sequential decision-making.
The most fundamental and well-studied models for sequential decision-making are
Markov chains (MCs), and their generalization Markov decision processes (MDPs).
The complexity theoretic study of MCs and MDPs with CPT is a fundamental problem
that has not been addressed in the literature.Our contributions are as follows:
First, we present an alternative viewpoint for the CPT-value of MCs and MDPs.
This allows us to establish a connection with multi-objective reachability analysis
and conclude the strategy complexity result that memoryless randomized strategies
are necessary and sufficient for optimality. Second, based on this connection,
we provide an algorithm for computing the CPT-value in MDPs with infinite-horizon
objectives. We show that the problem is in EXPTIME and fixed-parameter tractable.
Moreover, we provide a polynomial-time algorithm for the special case of MCs.'

text: Glacier melt sustains water discharge from mountain basins during droughts,
but ongoing glacier retreat threatens this fundamental capacity. Here, we assess
the response of glaciers in the Southern Andes to one of the most severe, persistent,
and extensive droughts on record in South America (2010-present), and to projected
end-of-century megadroughts. Using glacio-hydrological numerical simulations,
we show that despite a mean annual precipitation deficit of 36%, glacier runoff
in 2010-2019 remained almost unaltered compared to the preceding decade (2000-2009),
sustained by a 10% loss of total ice volume. However, simulations of future glacier
evolution indicate that annual and summer glacier runoff could decline by up to
20 ± 11% and 48 ± 6%, respectively, during end-of-century megadroughts compared
to pre-2010 levels. Our results project a weakening of the glacier’s buffering
role against precipitation deficits during extreme droughts, increasing water
scarcity for ecosystems and livelihoods in the mountain regions of South America.

text: Optical tweezers are widely used as a highly sensitive tool to measure forces
on micron-scale particles. One such application is the measurement of the electric
charge of a particle, which can be done with high precision in liquids, air, or
vacuum. We experimentally investigate how the trapping laser itself can electrically
charge such a particle, in our case a ∼1 μm SiO2 sphere in air. We model the
charging mechanism as a two-photon process which reproduces the experimental data
with high fidelity.

text: We experimentally realize a quantum clock by using a charge sensor to count
charges tunneling through a double quantum dot (DQD). Individual tunneling events
are used as the clock’s ticks. We quantify the clock’s precision while measuring
the power dissipated by the DQD and, separately, the charge sensor in both direct-current
and radio-frequency readout modes. This allows us to probe the thermodynamic cost
of creating ticks microscopically and recording them macroscopically. Our experiment
is the first to explore the interplay between the entropy produced by a microscopic
clockwork and its macroscopic measurement apparatus. We show that the latter contribution
not only dwarfs the former but also unlocks greatly increased precision, because
the measurement record can be exploited to optimally estimate time even when the
DQD is at equilibrium. Our results suggest that the entropy produced by the amplification
and measurement of a clock’s ticks, which has often been ignored in the literature,
is the most important and fundamental thermodynamic cost of timekeeping at the
quantum scale.

text: 'Understanding physiological responses during running is critical for performance
optimization, tailored training prescriptions, and athlete health management.
We introduce a comprehensive framework—what we believe to be the first capable
of predicting instantaneous oxygen consumption (VO2) trajectories exclusively
from consumer-grade wearable data. Our approach employs two complementary physiological
models: (1) accurate modeling of heart rate (HR) dynamics via a physiologically
constrained ordinary differential equation (ODE) and neural Kalman filter, trained
on over 3 million HR observations, achieving 1-second interval predictions with
mean absolute errors as low as 2.81 bpm (correlation 0.87); and (2) leveraging
the principles of precise HR modeling, a novel VO2 prediction architecture requiring
only the initial second of VO2 data for calibration, enabling robust, sequence-to-sequence
metabolic demand estimation. Despite relying solely on smartwatch and chest-strap
data, our method achieves mean absolute percentage errors of approximately 13%,
effectively capturing rapid physiological transitions and steady-state conditions
across diverse running intensities. Our synchronized dataset, complemented by
blood lactate measurements, further lays the foundation for future noninvasive
metabolic zone identification. By embedding physiological constraints within modern
machine learning, this framework democratizes advanced metabolic monitoring, bridging
laboratory-grade accuracy and everyday accessibility, thus empowering both elite
athletes and recreational fitness enthusiasts.'

text: In equilibrium, the physical properties of matter are set by the interactions
between the constituents. In contrast, the energy input of the individual components
controls the behavior of synthetic or living active matter. Great progress has
been made in understanding the emergent phenomena in active fluids, though their
inability to resist shear forces hinders their practical use. This motivates the
exploration of active solids as shape-shifting materials, yet, we lack controlled
synthetic systems to devise active solids with unconventional properties. Here
we build active elastic beams from dozens of active colloids and unveil complex
emergent behaviors such as self-oscillations or persistent rotations. Developing
tensile tests at the microscale, we show that the active beams are ultrasoft materials,
with large (nonequilibrium) fluctuations. Combining experiments, theory, and stochastic
inference, we show that the dynamics of the active beams can be mapped on different
phase transitions which are tuned by boundary conditions. More quantitatively,
we assess all relevant parameters by independent measurements or first-principles
calculations, and find that our theoretical description agrees with the experimental
observations. Our results demonstrate that the simple addition of activity to
an elastic beam unveils novel physics and can inspire design strategies for active
solids and functional microscopic machines.

text: Non-Hermitian many-body localization (NH MBL) has emerged as a possible scenario
for stable localization in open systems, as suggested by spectral indicators identifying
a putative transition for finite system sizes. In this work, we shift the focus
to dynamical probes, specifically the steady-state spin current, to investigate
transport properties in a disordered, non-Hermitian XXZ spin chain. Through exact
diagonalization for small systems and tensor-network methods for larger chains,
we demonstrate that the steady-state current remains finite and decays exponentially
with disorder strength, showing no evidence of a transition up to disorder values
far beyond the previously claimed critical point. Our results reveal a stark discrepancy
between spectral indicators, which suggest localization, and transport behavior,
which indicates delocalization. This highlights the importance of dynamical observables
in characterizing NH MBL and suggests that traditional spectral measures may not
fully capture the physics of non-Hermitian systems. Additionally, we observe a
noncommutativity of limits in system size and time, further complicating the interpretation
of finite-size studies. These findings challenge the existence of NH MBL in the
studied model and underscore the need for alternative approaches to understanding
localization in non-Hermitian settings.
