Photovoltaic Effect in a III‐IV‐V Compound Semiconductor

Progress in Photovoltaics: Research and Applications, EarlyView.
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

Phys-Diff: A Physics-Inspired Latent Diffusion Model For Tropical Cyclone Forecasting

ICASSP 2026 - 2026 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Tropical cyclone (TC) forecasting is critical for disaster warning and emergency response. Deep learning methods address computational challenges but often neglect physical relationships between TC attributes, resulting in predictions lacking physical consistency.

World Models for Robotic Manipulation: A Survey

SmartBot, EarlyView.
World models enable robots to anticipate how candidate actions may alter object configurations, contact states, and scene geometry before physical execution. This survey examines world models for robotic manipulation as action‐conditioned predictive systems and organizes the literature according to predicted representations, interfaces between ...

Trustworthy Imagination in Embodied World Models: Structural Constraints, Reality Anchoring, and Trust Adjudication

SmartBot, EarlyView.
World models let robots imagine alternative futures, such as successfully grasping a glass or dropping it, but visual plausibility alone does not establish trustworthiness. Here, the authors review structural constraint, reality anchoring, and trust adjudication as complementary mechanisms for shaping generation, grounding predictions in real evidence,

Ultra‐Tough Hybrid Supramolecular Gelatin Hydrogels

Small, EarlyView.
Tannic acid‐mediated coacervation compacts gelatin into a dense supramolecular network while generating an acidic microenvironment that activates pre‐embedded bis‐oxazoline crosslinkers. The resulting hybrid hydrogel combines covalent stabilization with reversible energy dissipation, producing high strength, extreme extensibility, substantial toughness,

Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack

Systems Engineering, EarlyView.
ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...

Image and video analysis using graph neural network for Internet of Medical Things and computer vision applications

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Graph neural networks (GNNs) have revolutionised the processing of information by facilitating the transmission of messages between graph nodes. Graph neural networks operate on graph‐structured data, which makes them suitable for a wide variety of computer vision problems, such as link prediction, node classification, and graph classification.

Towards data‐driven predictive maintenance for vacuum ion pumps at European XFEL

Journal of Synchrotron Radiation, EarlyView.
This paper presents a machine‐learning‐based approach for early fault detection in vacuum ion pumps at the European XFEL by analyzing pressure data to detect fault precursors. The developed method enables predictive maintenance, reducing unplanned downtime and improving operational reliability.Large‐scale scientific facilities, such as the European ...
