Attention-based time–frequency aggregated tokens for sound event classification in basketball game

Abstract With the rapid advancement of computer technology, its application in basketball game analysis has become a prominent research focus. Sound events in basketball games encapsulate critical game-related information. However, research on sound event classification in basket...

Reactive PLD Guides the Transformation to Noncrystalline C‐Ga‐Se‐Cl Films with a Halogen‐Defined Interface for Enhanced Luminescence

ABSTRACT Pulsed laser deposition is known for copying the composition of a target into a thin film. Adding a reactive gas can change the growth process, but the chemistry usually stays close to the target. Using a carbon‑rich environment and a pulsed chlorine source from polyviny...

Enabling generalizable RUL prediction for equipment: a dual-dimensional continual learning approach based on deep Gaussian process

Abstract Accurately predicting Remaining Useful Life (RUL) is critical for the intelligent maintenance of high-end rotating machinery, which often operates under complex and variable conditions. However, conventional predictive models tend to degrade in performance when deployed...

Interface Contact Optimization via Phosphomolybdic Acid Enables 24.9% Efficiency in MoOX-Based Silicon Solar Cells

Abstract The development of cost-effective carrier-selective passivating contacts is critical for enhancing the commercial feasibility of silicon compound solar cells. Molybdenum oxide (MoO X ) has garnered considerable interest as a promising hole transport layer (HTLs). A key a...
