A line in the water vapor maser spectrum of the HII region W3(OH) was observed to increase in brightness over an 8-day period and then decline to its original intensity over the following 4 weeks. The intensity variation can be explained by a simple maser model, with an impulse of energy suddenly applied. The observed time scale and energy output are(More)
This paper briefly describes how nanowires with diameters corresponding to 1 to 5 atoms can be produced by melting a range of inorganic solids in the presence of carbon nanotubes. These nanowires are extreme in the sense that they are the limit of miniaturization of nanowires and their behavior is not always a simple extrapolation of the behavior of larger(More)
The first section of this bibliography includes papers presented at conferences and meetings by RLE faculty, staff and students during 1987, and is in chronological order by the month the conference was held. Reprints of papers may be obtained by contacting the authors directly. Sections 30.2 and 30.3 are alphabetical listings by author of journal articles(More)
