Stability Bounds for the Generalized Kadanoff‐Baym Ansatz in the Holstein Dimer

Contributions to Plasma Physics, EarlyView.
ABSTRACT Predicting real‐time dynamics in correlated systems is demanding: exact two‐time Green's function methods are accurate but often too costly, while the Generalized Kadanoff‐Baym Ansatz (GKBA) offers time‐linear propagation at the risk of uncontrolled behavior. We examine when and why GKBA fails in a minimal yet informative setting, the Holstein

EventFlow: Real‐time neuromorphic event‐driven classification of two‐phase boiling flow regimes

Droplet, EarlyView.
We present a real‐time flow regime classification framework that integrates neuromorphic event‐driven sensing with deep recurrent neural networks. Unlike traditional frame‐based approaches, our system captures sparse event streams from an event‐based camera, representing only the dynamic brightness changes at the individual pixel level.

Construction of Sheet‐on‐Hollow Cube Cu2‐xS/ZnIn2S4 p‐n Heterojunction for Enhanced Visible‐Light‐Driven Photocatalytic Hydrogen Production

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The Cu2–xS/ZnIn2S4 composite photocatalyst is an ultrathin ZnIn2S4 nanosheet in situ grown on the surface of the Cu2–xS hollow cube, forming a unique p‐n junction structure, which exhibits excellent photocatalytic hydrogen production performance under visible light.

RuO2‐Based High‐Entropy Oxide and Its Asymmetric Catalysis on Polysulfide Conversion in Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
RuO2‐based high‐entropy metal oxide shows an asymmetric catalysis on polysulfide conversion with an inferior kinetics enhancement of polysulfide generation, but a superior promotion of Li2S deposition, which greatly favors the inhibition of shuttle effect and the improvement of battery performance. High‐entropy oxides with five or more metal components

A Novel Multilevel Conceptual Framework for Flood Risk Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Globally, flood risk is increasing as climate change progresses. Contemporary flood risk management practice often utilises hydrodynamic modelling (for hazard risk assessments), social vulnerability assessments, and risk communications in silo, which fragments evidence‐based decision‐making for effective flood risk management. We hence develop

Test results for 20-GHz GaAs FET spacecraft power amplifier [PDF]

Test were conducted to measure the performance of the 20-GHz solid state, proof-of-concept amplifier. The amplifier operates over the 17.7 to 20.2-GHz frequency range and uses high power gallium arsenide field effect transistors. The amplifier design and

Are seizure forecasts and cycles better than chance? What chance?

Epilepsia, EarlyView.
Abstract Objective There is a growing synergy between the lines of research on cycles in epilepsy and seizure forecasting. It has been conjectured, for instance, that incorporating information about significant seizure cycles into forecasting algorithms can lead to a better‐than‐chance forecasting performance.
