A Steerable and Expandable Magnetic Aspiration Catheter for Enhanced Aspiration Thrombectomy
Advanced Intelligent Systems, EarlyView.This article presents a novel magnetic aspiration catheter (MAC) that can be both actively steered and undergo distal‐end expansion via externally applied magnetic fields. The MAC facilitates precise branch selection and enhances clot engagement by improving endovascular navigation and aspiration efficiency. Phantom experiments validate its feasibility

On Dynamic Properties of Two Models of Beam on Nonlinear Foundation Subjected to Moving Load
Engineering Transactions, 1993 The subjects of consideration are the infinite Bernoulli - Euler and Timoshenko models of a beam resting on a nonlinear visco-elastic foundation. The beams are subjected to a distributed inertialess loading constant in a given sector and moving with a ...

Scalable High‐Force Zipping Electrostatic Actuators
Advanced Intelligent Systems, EarlyView.An electrostatic actuator architecture is presented that combines high energy density with forces and strokes suited for wearable soft robotics. By folding patterned thin films into a scalable honeycomb of zipping units, performance becomes tunable through series–parallel design, achieving over 40 N and 28 J/kg.

Nonlinear Vibration Characteristic Analysis of Electric Vehicle–Road Coupling System
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In‐wheel motor drive is the developing direction of automobile electrification and intelligence. However, the increased unsprung mass in in‐wheel motor‐driven electric vehicles (IWMEVs) leads to higher dynamic tire loads, thereby intensifying vehicle–road coupling interactions. To address this problem, an 11‐degree‐of‐freedom nonlinear dynamic
