The physical mechanisms and physiological causes of glare in human vision are reviewed. These mechanisms are scattering in the cornea, lens, and retina, and diffraction in the coherent cell structures on the outer radial areas of the lens. This scattering and diffraction are responsible for the " bloom " and " flare lines " seen around very bright objects.(More)
In the past decade, we have witnessed a quantum leap in rendering technology and a simultaneous increase in usage of computer generated images. Despite the advances made thus far, we are faced with an ever increasing desire for technology which can provide a more realistic, more immersive experience. One fledgeling technology which shows great promise is(More)

Thermophilic microbial inhabitants of active seafloor and continental hot springs populate the deepest branches of the universal phyloge-netic tree, making hydrothermal ecosystems the most ancient continuously inhabited ecosystems on Earth. Geochemical consequences of hot water-rock interactions render these environments habitable and supply a diverse array(More)
