Nano Letters, 2012
We experimentally demonstrate the directional emission of polarized light from single semiconductor nanowires. The directionality of this emission has been directly determined with Fourier microphotoluminescence measurements of vertically oriented InP nanowires.

Emission uniformity and emission area of explosive field emission cathodes
Applied Physics Letters, 2001Explosive field emission cathodes have been used extensively in high power microwave tubes. These cathodes emit electrons without the use of cathode heaters. Recently, some theoretical and simulation work has been performed to gain further understanding of the physics of these cathodes.

Neurosurgery, 1978
Emission computed tomography (CT) is a nuclear medicine visualization technique that yields an image of the distribution of a previously administered radionuclide in any desired transverse section of the body. Emission CT allows the safe, quantitative, three-dimensional measurement of regional radionuclide distribution in tissue.

Annual Review of Neuroscience, 1980
An understanding of disease processes in the human brain must ultimately be based on a knowledge of the underlying regional hemodynamic, metabolic, and biochemical changes. Although some such information is currently available from various animal models, the conflicting nature of these data often leaves many important questions unanswered and ...

Subsistence Emissions and Luxury Emissions
Law & Policy, 1993The United Nations Framework Convention on Climate Change adopted in Rio de Janeiro at the United Nations Conference on Environment and Development (UNCED) in June 1992 establishes no dates and no dollars. No dates are specified by which emissions are to be reduced by the wealthy states, and no dollars are specified with which the wealthy states will ...
