The effect of failure mechanics on the fatigue responses of lumbar intervertebral disc [0.03%]
损伤力学对腰椎间盘疲劳性能的影响研究
Qing Liu,Qi Zhang,Chun-Qiu Zhang et al.
Qing Liu et al.
Lumbar disc herniation is usually caused by the accumulation of long-term mechanical loads and sudden overload damage. Therefore, this study aims to illustrate how fatigue failure in lumbar spine segments is influenced by both cyclic loadin...
A proposal for the combined analysis of bone quantity and quality of human cortical bone by quasi-brittle fracture mechanics [0.03%]
基于准脆性断裂力学的人骨皮质骨量化和质化联合分析方法学建议

People with balance impairments often struggle performing turns or lateral maneuvers, which can increase risk of falls and injuries. Here we asked how people's mediolateral balance is impacted when walking on non-straight winding paths. Twe...
Novel arthrometer for quantitative clinical examination of the knee in three planes: Safety, reliability, minimum detectable changes, and side-to-side differences in healthy subjects [0.03%]
一种新型膝关节量角器的临床研究：安全性和可靠性、健康受试者各向最小可检测变化及 limbs差距测量
