Active Vibration Suppression of a 3‐DOF Flexible Parallel Manipulator Using Efficient Modal Control
Shock and Vibration, Volume 2014, Issue 1, 2014., 2014 This paper addresses the dynamic modeling and efficient modal control of a planar parallel manipulator (PPM) with three flexible linkages actuated by linear ultrasonic motors (LUSM). To achieve active vibration control, multiple lead zirconate titanate (PZT) transducers are mounted on the flexible links as vibration sensors and actuators.

Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review
Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

Advanced Science, Volume 12, Issue 30, August 14, 2025.KRAS mutations dynamically remodel the tumor microenvironment (TME), fostering immunosuppression, metabolic symbiosis, and stromal plasticity. This review dissects how oncogenic KRAS variants sculpt TME networks and explores actionable vulnerabilities. Emerging strategies combining KRAS inhibitors and TME‐editing approaches offer potential to dismantle
