Advances and Prospects of Stereotactic Radiosurgery and Stereotactic Ablative Body Radiotherapy: Evolving Paradigms in Precision Oncology

open access: yesMed Research, EarlyView.
The graphical abstract outlines the progressive development and impact of stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT). Technological Evolution illustrates the transition from brachytherapy with single‐dose, LDR/HDR schedules to fractionated radiotherapy, three‐dimensional conformal radiotherapy (3DCRT) and Gamma Knife ...

Spatiotemporal Encoding With Nonlinear Gradient Hardware Using Pulseq: From Principles to Practical Demonstration

open access: yesMagnetic Resonance in Medicine, EarlyView.
Purpose Provide the theoretical foundation and the first practical demonstration of spatiotemporal encoding (SPEN) using additional nonlinear gradient hardware. Methods The quadratic phase profile can be generated either by a chirped‐RF pulse combined with a constant gradient or, directly, by a quadratic gradient pulse.

Predefined‐Time Dynamic Surface Control of Tank Horizontal Stabilization System With Disturbance

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern new tanks are difficult to achieve high precision control of the horizontal stabilization system due to electromechanical coupling and road surface disturbance during high‐speed combat. A predefined‐time dynamic surface controller (DSCPT) is proposed for the fast stabilization and strong disturbance problems of the tank horizontal ...

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

Rehabilitation paired with vagus nerve stimulation for motor function of chronic ischemic stroke patients in China: Study protocol of a multicenter randomized controlled trial (Repair Study)

open access: yesNeuroprotection, EarlyView.
Mechanism of vagus nerve stimulation (VNS) paired with movement: VNS activates cholinergic nucleus basalis and noradrenergic locus coeruleus neurons, modulating motor cortex activity (light green and red areas) in a task‐specific manner during targeted movements. VNS: vagus nerve stimulation.
