Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Stator grounding fault severity characterization and novel inverse-time protection method for large generators

International Journal of Electrical Power & Energy Systems
The existing injection-type stator grounding protection schemes for large generators are configured to issue only an alarm signal under high transition resistance grounding fault conditions. Thus, the fault cannot be promptly cleared.

Fault section locating method and recovery strategy of pole-to-ground fault for medium voltage direct current (MVDC) distribution network

The Journal of Engineering, 2019
High-resistance clamping grounding is a common grounding mode of modular multilevel converter (MMC) based DC distribution network. Due to the current limiting function of grounding resistor, pole-to-ground fault can only cause limited steady-state fault ...

Current Tracking Adaptive Control of Brushless DC Motors

International Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.
