Piezo proteins have been proposed as the long-sought-after mechanosensitive cation channels in mammals that play critical roles in various mechanotransduction processes. However, the molecular bases that underlie their ion permeation and mechanotransduction have remained functionally undefined. Here we report our finding of the miniature pore-forming module(More)
Although hand tracking algorithm has been widely used in virtual reality and HCI system, it is still a challenging problem in vision-based research area. Due to the robustness and real-time requirements in VR applications, most hand tracking algorithms require special device to achieve satisfactory results. In this paper, we propose an easy-to-use and(More)
Virtual reality (VR) is being applied to a wide range of medical areas, including medical education/training, surgery and diagnostics assistance. In the medical education field, VR opens new realms in the teaching of medicine and creates new effective learning procedures for the students. In contrast with the expensive immersive virtual reality learning(More)
This paper presents a private subdivision surface watermarking algorithm. The subdivision schemes include Doo-Sabin Subdivision and Loop Subdivision. The subdivision surface watermarking algorithm includes three main steps as followings. First, the resultant watermarked image minus the original image is the watermark information. The image watermarking(More)
