3 days ago · The analysis revealed that when users are viewing VR displays, optimization of the distance to the optical center of the VR-device lenses and correction of the refractive errors for individual ...
2 days ago · As automakers evaluate suppliers, they should consider the quality of both the measurement scales and optics incorporated in vision machines. Currently, only a handful of vision system makers provide optics with the exacting level of precision and durability needed to ensure proper quality control in the high-volume measurement of plastic parts, making this a critical factor in evaluating ...
3 days ago · The auditory system is also notable for its temporal sensitivity; time differences as small as 10 μs can be detected. Auditory pathways resemble other sensory systems, however, in that different features of acoustic information are processed in discrete circuits that eventually converge to form complex representations of sound. + +
2 days ago · The superior colliculus receives powerful synaptic inputs from corticotectal neurons in the visual cortex. The function of these corticotectal neurons remains largely unknown due to a limited understanding of their response properties and connectivity. Here, we use antidromic methods to identify corticotectal neurons in awake male and female rabbits, and measure their axonal conduction times ...
2 days ago · This study aimed to determine the pars plana length in postmortem human eyes using advanced morphometric techniques and correlate demographics to ocular metrics such as age, sex, ethnicity, and axial length. Between February and July 2005, we conducted a cross-sectional observational study on 46 human cadaver eyes deemed unsuitable for transplant by the SBO Eye Bank. The morphometric analysis ...
3 days ago · Background: The aim of this study is to determine the relationship between selected components of body composition and the phase angle specified by bioelectrical impedance analysis, depending on the level of physical activity among students. Materials and Methods: The study group consisted of 484 university students from Krosno. The diagnostic survey method (IPAQ-SF), measurements of highs ...
5 days ago · 22. Sperm cells are the smallest cells in the human body, while egg cells are the largest. This size difference is one of nature's many fascinating contrasts. 23. The average lifespan of a sperm cell in the female reproductive tract is about 5 days, providing a brief window for fertilization to occur. 24.
