1Full-field strain mapping for characterization of structure-related variation in corneal biomechanical properties using digital image correlation(DIC)technology显示文摘Characterization of structure-related variation in corneal biomechanical properties is important for the design of corneal implants with a controllable degradation.In the current study,we conducted an in-vitro inflation experiment on contact and structural-damaged porcine corneas and mapped the strain distribution during using digital image correlation(DIC)algorithm.The inflation experiment was performed with a pressure loading device,a steady-state pressure transducer and DIC system.Corneal samples with uniformly-distributed paint particles were fixed on the loading device,and then were subjected increasing pressure load through injection with a constant velocity(0.134 ml/min).Three-dimensional(3D)DIC algorithm was performed to present a map of the full-field strain distribution on the corneal surface.The results showed a significant difference in the strain distribution between the intact and damaged corneas.The time-strain history also exhibited differently when the two types of cornea samples were subjected to inflation.It indicated that the DIC technology is validated to characterize structure-related variation in corneal biomechanical properties.Xiaofeng Qiao Duo Chen Hongqiang Huo Min Tang Zhili Tang Ying Dong Xiaoyu Liu Yubo Fan 2021Medicine in Novel Technology and Devices2021,,3:0
2Sex differences in eye movements and neural oscillations during mental rotation in virtual reality显示文摘Virtual reality(VR)has been a promising tool for developing visuospatial tasks.Among visuospatial tasks,mental rotation tasks are widely used in the assessment of visuospatial ability.Males have a distinct advantage in mental rotation ability compared to females,yet it is generally produced by investigations based on two-dimensional(2D)images on a computer screen.Sex differences in mental rotation tasks with three-dimensional(3D)objects in VR were not fully investigated.It is unclear whether the male's advantages in 2D mental rotation tasks are weakened in 3D tasks.The aim of this study was to provide new insights into the understanding of sex differences in mental rotation tasks presented in VR.Here,we developed a VR mental rotation task(VR-MRT)using 3D objects presented by a head-mounted display(HMD)and used VR-based eye tracking and electroencephalography(EEG)to examine eye movements and neural oscillations for males and females.Our results showed that females preferred a piecemeal strategy compared to males,suggesting a significant sex difference in visual strategy.More importantly,we found no significant sex differences in alpha-band and beta-band oscillations related to rotation processes of VR-MRT.These findings indicated that sex differences in the VR-MRT were mainly attributed to the selection of visual strategy rather than the rotation processes.The study helps to comprehensively understand the dominant factors contributing to the sex differences in the VR-MRT.Zhili Tang Xiaoyu Liu Hongqiang Huo Min Tang Xiaofeng Qiao Duo Chen Ying Dong Linyuan Fan Jinghui Wang Xin Du Jieyi Guo Yubo Fan 2023Medicine in Novel Technology and Devices2023,,2:0
