Influence of Velocity Feedback Time Delay on the Nonlinear Dynamic Characteristics of Maglev Trains Under Unsteady Aerodynamic Forces

International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 707-720, December 2025.
ABSTRACT Time delays frequently arise in active control systems due to sensor sampling, signal transmission, and actuator response, making their effects on system dynamics non‐negligible. This paper investigates how velocity feedback time delay influences the nonlinear dynamic characteristics of a maglev train subjected to unsteady aerodynamic forces ...

Analysis of outcomes in patients with HeartMate 3 with and without right ventricular assist device support

ESC Heart Failure, Volume 12, Issue 5, Page 3306-3319, October 2025.
Temporary RVAD support following HM3 LVAD is associated with high morbidity and mortality. Temporary RVAD support occurs most frequently in INTERMACS 1 or 2 patients and those who require pre‐operative VA‐ECMO. In addition to higher post‐operative mortality, a significantly higher risk of both dialysis and stroke at 1 year post‐implant was observed in ...
