Celestial MUSYC: cosmic ABCs keep astronomers spellbound: Acronyms are everywhere, alphabetically infecting daily life, IMHO in my humble opinion. So perhaps we astronomers can be forgiven for sliding down the slippery slope of cryptic capital letters: MHD magnetohydrodynamics, SETI search for extraterrestrial intelligence, LGM little green men. Overall, though, we're pretty good at keeping things unacronymed,...; Tags: ABC Inc., electron, hydrogen, MARKETING, radiation, survey, wavelength; Research articles 2006-09-01
Who's Who at NASA: Dr. Murzy Jhabvala, Chief Engineer, Instrument Systems and Technology Division, Goddard Space Flight Center, Greenbelt, MD Visible light is only one narrow band of the electromagnetic spectrum, and doesn't always tell scientists what they need to know. Infrared, which is outside the range of human eyesight, has for years been...; Tags: Dr., HARDWARE, NASA, Semiconductors, wavelength; Research articles 2006-08-01
Exact Tuning of High-Q Optical Microresonators by Use of UV: Resonance frequencies can be shifted permanently by controlled amounts. In one of several alternative approaches to the design and fabrication of a "whispering-gallery" optical microresonator of high resonance quality high Q, the index of refraction of the resonator material and, hence, the resonance frequencies (which depend on the...; Tags: laser, NASA, wavelength; Research articles 2006-05-01
Optical Systems Improve Nerve Stimulation: An infrared laser-based nerve stimulation system eliminates electrical stimulation artifacts, and improves nerve target specificity.
