Validation Study on Fault Diagnosis of Elevator Traction Drive Systems Based on Public Motor-Drive Data and Multimodal Signal Analysis

To address the difficulty of obtaining real fault data from elevator traction drive systems and the potential overestimation caused by random window splitting, this study uses two public motor-drive datasets to examine how validation protocols, signal modalities, and noise condit...

Endowing CentrosymmetricOxides with Effective Piezoelectricityvia Oxygen Vacancy Engineering and Single-Atom Anchoring for MulticatalyticSono-Immunotherapy

Abstract Due to piezopotential-driven energy band tilting and the promotion of charge carrier separation, sonopiezoelectric therapy (SPT) holds promise in overcoming the limitations of band structure. However, the dependence of the piezoelectric effect on noncentrosymmetric cryst...
