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: Qualitative and quantitative orbital properties such as bonding/antibonding
character, localization, and orbital energies are critical to how chemists understand
reactivity, catalysis, and excited-state behavior. Despite this, representations
of orbitals in deep learning models have been very underdeveloped relative to
representations of molecular geometries and Hamiltonians. Here, we apply state-of-the-art
equivariant deep learning architectures to the task of assigning global labels
to orbitals, namely energies characterizations, given the molecular coefficients
from Hartree–Fock or density functional theory. The architecture we have developed,
the Cartesian Equivariant Orbital Network (CEONET), shows how molecular orbital
coefficients are readily featurized as equivariant node features common to all
graph-based machine-learned potentials. We find that CEONET performs well at predicting
difficult quantitative labels such as the orbital energy and orbital entropy.
Furthermore, we find that the CEONET representation provides an intuitive latent
space for differentiating orbital character for the qualitative assignment of
e.g. bonding or antibonding character. In addition to providing a useful representation
for further integrating deep learning with electronic structure theory, we expect
CEONET to be useful for automatizing and interpreting the results of advanced
electronic structure methods such as complete active space self-consistent field
theory. In particular, the ability of CEONET to infer multireference character
via the orbital entropy paves the way toward the machine-learned selection of
active spaces.

text: Generative models have advanced significantly in sampling material systems
with continuous variables, such as atomistic structures. However, their application
to discrete variables, like atom types or spin states, remains underexplored.
In this work, we introduce a discrete flow matching model, tailored for systems
with discrete phase-space coordinates (e.g., the Ising model or a multicomponent
system on a lattice). This approach enables a single model to sample free energy
surfaces over a wide temperature range with minimal training overhead, and the
model generation is scalable to larger lattice sizes than those in the training
set. We demonstrate our approach on the 2D Ising model, showing efficient and
reliable free energy sampling. These results highlight the potential of flow matching
for low-cost, scalable free energy sampling in discrete systems and suggest promising
extensions to alchemical degrees of freedom in crystalline materials. The codebase
developed for this work is openly available at https://github.com/tuoping/alchemicalFES.

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.

text: 'Mountain glaciers offer opportunities to observe boundary layer exchanges
in conditions characterized by predominantly stable stratification, thermally
driven winds, and varying surface roughness. Logistical challenges involved in
instrumenting glacier surfaces mean that in situ observations remain relatively
scarce, limiting the use of this outdoor laboratory. The second Hintereisferner
Experiment (HEFEX II) was carried out on an Austrian Alpine glacier during summer
2023. This collaborative endeavor, involving 12 institutions from Austria, France,
Germany, Switzerland, and the United Kingdom, represents an unprecedented set
of observations of glacier microclimate. Instrumentation on the glacier surface
consisted of eight 3-m and two 5-m weather stations equipped with multilevel eddy
covariance systems and auxiliary instrumentation, and eight additional lower-specification
weather stations. These operated successfully for 26 days with minimal data gaps.
During a 3-day intensive observational period, additional instrumentation was
deployed: a short-path ultrasonic anemometer installed very close to the glacier
surface; a high-speed thermal camera capturing high-resolution boundary layer
heat transport at the glacier centerline on a synthetic screen; 3D sampling of
the glacier boundary layer using two meteorological UAVs; and a Streamline XR
Doppler lidar capturing the structure of the above-valley atmosphere. These novel
datasets are valuable for improving understanding of glacier–atmosphere exchange
processes, the role of glaciers in valley circulation, and how both might be affected
by continued climate change and glacier recession. Here, we detail the scientific
goals and implementation of the campaign, describe the general weather conditions,
and present first insights into what the observations reveal about the glacier
boundary layer features observed during the campaign.'

text: The canonical mechanism by which the phytohormone auxin regulates transcription
has been one of the cornerstones of plant signaling. The recent unexpected discovery
of cyclic AMP (cAMP) as a second messenger in this pathway has revised its foundations
while leaving many open questions and gaps in our understanding; these will be
discussed in this forum article.

text: Glaciers are often located in steep mountain settings and avalanches from
surrounding slopes can strongly influence snow accumulation patterns on their
surface. This effect has however never been quantified for more than a few glaciers
and the impact on the future evolution of glaciers is unclear. We coupled an avalanche
and a glacier model to estimate the contribution of avalanches to the accumulation
of all glaciers in the world and how this affects their evolution throughout the
21st century. Globally, 3% of the snow accumulation on glaciers comes from avalanches
and 1% is removed by avalanches. This net contribution varies between regions
and glaciers, with a maximum of 15% for New Zealand. Accounting for avalanches
modifies the altitudinal pattern of glacier mass balance and the projected evolution
of individual glaciers. The main effects include (1) a longer persistence of small
glaciers, with for example three times more ice retained by glaciers smaller than
1 km2 in Central Europe under a low-emission scenario, and (2) an increased sensitivity
of high-elevation accumulation zones to future warming. We anticipate the relative
influence of avalanches to increase in the future and advocate for a better monitoring
of this process and representation in glacier models.

text: 'Persistence modules (defined as a sequence of vector spaces and linear maps
between them) are a key tool in topological data analysis. They are easy to interpret
and fast to compute. However, when considering persistence maps (i.e. maps between
persistence modules), these properties are lost. We propose a new invariant for
persistence maps consisting of a partial matching such that: it is easy to interpret,
it is more discriminative than the image of the persistence map, and can be calculated
with cubical complexity.'

text: Radio-frequency measurements could satisfy DiVincenzo’s readout criterion
in future large-scale solid-state quantum processors, as they allow for high bandwidths
and frequency multiplexing. However, the scalability potential of this readout
technique can only be leveraged if quantum device tuning is performed using exclusively
radio-frequency measurements, that is, without resorting to current measurements.
We demonstrate an algorithm that performs automatic coarse tuning of double quantum
dots with only radio-frequency measurements by exploiting their bandwidth and
impedance matching. The tuning was completed within a few minutes with minimal
prior knowledge about the device. Our results show that it is possible to eliminate
the need for transport measurements for quantum-dot tuning, paving the way for
more scalable device architectures.

text: The adult human brain, under resting conditions, consumes approximately 20%
of total body glucose, a demand that is even higher during the first decade of
life. The brain metabolic landscape is intricately regulated throughout development,
and each cell type exhibits distinct metabolic signatures at each specific stage.
This picture becomes even more intricate when considering that metabolism is dynamically
modulated to sustain critical biological processes, such as cell proliferation
and differentiation and synaptic activity–dependent processes. The orchestration
between metabolic regulation and the aforementioned physiological processes often
relies on metabolism-dependent changes in the epigenetic landscape, which shape
gene expression patterns to trigger selected downstream biological responses.
Perturbations of brain metabolic pathways are frequently the cause of severe neurodevelopmental
disorders. This review explores the latest insights into the regulation of brain
metabolism in health and disease.

text: 'We investigate the real-time dynamics of a quenched quantum impurity immersed
in a one-dimensional ultracold Fermi gas, focusing on the breakdown of the adiabatic
Born-Oppenheimer approximation due to nonadiabatic effects. Despite a sizable
impurity-bath mass imbalance, increasing interactions induce strong nonadiabatic
couplings, disrupting adiabatic motion and enabling population transfer between
the adiabatic potential energy curves. These transitions are governed by conical
intersections arising from the pseudo Jahn-Teller effect, dynamically shaping
the impurity''s motion through the bath. Using ab initio simulations via the multilayer
multiconfiguration time-dependent Hartree method and a multichannel Born-Oppenheimer
framework, we track the impurity''s evolution and directly prove the dynamical
manifestation of the pseudo Jahn-Teller effect. We analyze two key scenarios:
(i) a small initial shift, where a single avoided crossing drives transitions,
and (ii) a large shift, where multiple avoided crossings lead to enhanced nonadiabaticity,
self-trapping, and energy redistribution. Our findings establish ultracold fermionic
few-body systems as tunable platforms for studying nonadiabatic quantum dynamics,
opening new avenues for controlled impurity transport in strongly correlated environments.'

text: The conversion of thermal energy into work is usually more efficient in the
slow-driving regime, where the power output is vanishingly small. Efficient work
extraction for fast-driving protocols remains an outstanding challenge at the
nanoscale, where fluctuations play a significant role. In this Letter, we use
a quantum-dot Szilard engine to extract work from thermal fluctuations with maximum
efficiency over two decades of driving speed. We design and implement a family
of optimized protocols ranging from the slow- to the fast-driving regime, and
we measure the engine's efficiency as well as the mean and variance of its power
output in each case. These optimized protocols exhibit significant improvements
in power and efficiency compared to the naive approach. Our results also show
that, when optimizing for efficiency, boosting the power output of a Szilard engine
inevitably comes at the cost of increased power fluctuations.

text: We consider the problem of parameter estimation in a high-dimensional generalized
linear model. Spectral methods obtained via the principal eigenvector of a suitable
data-dependent matrix provide a simple yet surprisingly effective solution. However,
despite their wide use, a rigorous performance characterization, as well as a
principled way to preprocess the data, are available only for unstructured (i.i.d.
Gaussian and Haar orthogonal) designs. In contrast, real-world data matrices are
highly structured and exhibit non-trivial correlations. To address the problem,
we consider correlated Gaussian designs capturing the anisotropic nature of the
features via a covariance matrix Σ. Our main result is a precise asymptotic characterization
of the performance of spectral estimators. This allows us to identify the optimal
preprocessing that minimizes the number of samples needed for parameter estimation.
Surprisingly, such preprocessing is universal across a broad set of designs, which
partly addresses a conjecture on optimal spectral estimators for rotationally
invariant models. Our principled approach vastly improves upon previous heuristic
methods, including for designs common in computational imaging and genetics. The
proposed methodology, based on approximate message passing, is broadly applicable
and opens the way to the precise characterization of spiked matrices and of the
corresponding spectral methods in a variety of settings.

text: Chemistry education at the graduate level and beyond faces the formidable
challenge of a boundless and constantly expanding frontier of knowledge on many
fronts. While modern learners have an increasingly broad range of resources available
at their disposal (including open access text-based references, online videos,
training problems, and other digital learning materials), there are comparatively
fewer such materials aimed at the highest levels of study. With the goal of producing
widely accessible graduate-level learning content, we created a community-based
approach to online course design that is easily digestible to meet the expectations
of modern learners. Herein, we report the development of an open access Advanced
Organic Chemistry video-based online course and several other specialized minicourses
using the Synthesis Workshop YouTube channel.
