30.1 INTRODUCTION Polycapillary and multichannel plate optics are both arrays of a large number of small hollow glass tubes and both depend on total reflection at the glass surface to transport X rays. The critical angle for borosilicate glass is approximately θ c ≈ mrad (1) which is 30 mrad (1.7°) for 1-keV photons and 1.5 mrad (0.086°) for 20-keV photons.(More)
Human subjects were vertically oscillated in the dark over a frequency range of 1-0.02 HZ at peak-to-peak acceleration amplitudes of 0.2-0.6 g, using both a vertical movement simulator and real flight. Subjective tracking of the movement was unreliable and showed no systematic dependence of phase upon frequency. In contrast, reflex oculomotor response,(More)
Newborn screening (NBS) is a complex process that has high-stakes health implications and requires rapid and effective communication between many people and organizations. Currently, each NBS laboratory has its own method of reporting results to state programs, hospitals and individual providers, with wide variation in content and format. Pediatric care(More)
Todays most compelling virtual reality experiences shift the users viewpoint within the virtual environment based on input from a head-tracking system, giving a compelling sense of motion parallax. While this is straightforward for computer generated scenes, photographic VR content generally does not provide motion parallax in response to head motion. Even(More)
Human-Engine is an innovative new approach to 3D asset creation, using 4D scan data to create lifelike virtual humans, clothing or anything else you can put in front of a camera. Our goal is to bridge the gap between traditional video capture and existing CG technology by creating accurate scans of humans and objects in motion that combine the realism of(More)
