Fault diagnosis method of a cascaded H‐bridge inverter based on a multisource adaptive fusion CNN‐transformer

IET Power Electronics, EarlyView.
The multisource adaptive fusion CNN‐transformer method proposed in this study can provide theoretical and technical support for fault diagnosis of high‐voltage MCHBI. It has a promising potential for engineering applications. Abstract In high‐voltage applications, the number of cascaded H‐bridge inverter units is large, the failure probability ...

Value of ultra‐high‐field MRI in patients with drug‐resistant focal epilepsy and negative 3T MRI (EpiUltraStudy): Diagnostic gain of 7T structural analysis

Epilepsia, EarlyView.
Abstract Objective Resective epilepsy surgery is an evidence‐based treatment option for patients with focal drug‐resistant epilepsy (DRE). Seizure outcome after surgery is largely dependent on detection and delineation of an epileptogenic lesion on magnetic resonance imaging (MRI). However, detection fails in 30% of patients at 3 Tesla (T) MRI, thereby
