With technological progress, wide field-of-view (FOV) displays will become increasingly common. Wide FOVs provide a more immersive environment and produce stronger self-motion perception. The objective of this study was to investigate the relationships between FOV and scene content on postural stability in an immersive environment. 10 subjects were tested(More)
Image quality issues such as field of view (FOV) and resolution are important for evaluating "presence" and simulator sickness (SS) in virtual environments (VEs). This research examined effects on postural stability of varying FOV, image resolution, and scene content in an immersive visual display. Two different scenes (a photograph of a fountain and a(More)
In this paper, we report a study that examines the relationship between image-based computational analyses of web pages and users' aesthetic judgments about the same image material. Web pages were iteratively decomposed into quadrants of minimum entropy (quadtree decomposition) based on low-level image statistics, to permit a characterization of these pages(More)
This study developed a new procedure, a Virtual Guiding Avatar (VGA), which combined self-motion prediction cues and an independent visual background (IVB) to alleviate simulator sickness (SS). The VGA, which was embodied as an abstract airplane, was designed to lead the participant along a horizontal motion trajectory through a virtual environment. Both(More)
A TPV GaSb cell was tested as part of an effort to establish a standard method of characterizing such cells. Cell current/voltage (IV) curves were measured at different cell temperatures using black body radiation at various emission temperatures and intensities. The results of the effects on performance are briefly analyzed and include temperature(More)
Natural Killer (NK) cells are essential for control of viral infection and cancer. NK cells express NKG2D, an activating receptor that directly recognizes NKG2D ligands. These are expressed at low level on healthy cells, but are induced by stresses like infection and transformation. The physiological events that drive NKG2D ligand expression during(More)
Nanoparticle-based therapeutics are being used to treat patients with solid tumors. Whereas nanoparticles have been shown to preferentially accumulate in solid tumors of animal models, there is little evidence to prove that intact nanoparticles localize to solid tumors of humans when systemically administered. Here, tumor and adjacent, nonneoplastic tissue(More)
