Exteroceptive Reflexes in Stiff Person Syndrome, Other Neurological Conditions and Healthy Controls

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Stiff person syndrome (SPS) is a rare disabling neurological condition with overlapping symptomatology with more common neurological conditions. Exaggerated exteroceptive reflex mechanisms are thought to play a role in its pathophysiology.

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Stability Analysis of a Receiving-End VSC-HVDC System with Parallel-Connected VSCs

Electronics
Voltage source converter-based high-voltage direct current (VSC-HVDC) systems integrated into weak AC grids may exhibit oscillation-induced instability, posing significant threats to power system security. With increasing structural complexity and diverse control strategies, the stability characteristics of VSC-HVDC system require further investigation.

Comprehensive Design and Experimental Validation of 30 kV Ultra‐Fast Flexible Controllable Arresters for HVDC Systems

High Voltage, EarlyView.
ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.
