Effect of pressure biofeedback training combined with Liuzijue Qigong training on respiratory function improvement in post-stroke patients with tracheotomy and decannulation: study protocol for a randomised controlled trial

Dan Wu, Yu Zheng, Qing Liu, Pengfei Shen et autres

Introduction Stroke causes neurological deficits and respiratory dysfunction, with prolonged bed rest exacerbating secondary pulmonary injury. This study evaluated the efficacy of pressure biofeedback training combined with Liuzijue Qigong (LQG) in improving functional outcomes and respiratory function in patients with tracheostomised stroke. …

Pressure-Induced Polyhedral Reorganization Causes Indirect-to-Direct Band-Gap Transition in Spinel Structure

Pengfei Shen, Donghao Xu, Zhiguo Xia, Mingguang Yao

Spinel oxides (AB_{2}O_{4}) are promising optoelectronic materials due to their structural stability and tunable electronic properties. However, conventional strategies like doping, element substitution, and thermal treatment have achieved limited success in optimizing their performance. Here, we demonstrate that pressure-induced polyhedral reorganization triggers …

Giant Negative Compressibility in 2D Hybrid Perovskites via Configuration Transition and Rotation of Carbon Chains

Pengfei Shen, Chunguang Zhai, Donghao Xu, Yongtao Zou et autres

Abstract Applying compressive force typically causes materials to shrink (or expand under tension). Materials that exhibit anomalous volume expansion upon compression (VEUC) present significant challenges and are the subject of extensively research. Here, it is discovered that (C 8 H 17 NH …
