D. L. Veasey, David S. Funk, P. M. Peters, Norman Sanford, Gregory E. Obarski, N. H. Fontaine, M. Young, A P. Peskin, W. Liu, S. N. Houde-Walter, Joseph S. Hayden
We present experimental and theoretical results of our recent work on the development of waveguide lasers using rare-earth-doped phosphate glasses. An

Perceptual Effects of Noise in Digital Video Compression

Author(s)
Charles D. Fenimore, John M. Libert, S. A. Wolf
This paper presents the results of subjective viewer assessment of the quality of MPEG-2 compressed video containing wideband Gaussian noise. The video test

Variance of Streaming Potential Measurements

Author(s)
M C. Wilbert, S Delagah, John Pellegrino
We evaluated sources of variance in the measurement of the surface streaming potential of flat sheet specimens of cellulose di/triacetate membranes with a

A Stall Metric to Track Communication Performance

Author(s)
Alan Mink, Wayne J. Salamon, Michael D. Indovina
Probing the communication protocol stack in Linux PC-based clusters to investigate erratic TCP/IP performance has led to a new metric, data stream stall, which

Thermodynamics of Reactions Catalyzed by Anthranilate Synthase

Author(s)
W M. Byrnes, Robert N. Goldberg, Marcia J. Holden, M P. Mayhew, Yadu D. Tewari
Microcalorimetry and high performance liquid chromatography have been used to conduct a thermodynamic investigation of reactions catalyzed by anthranilate

Dielectric Ceramic Materials

Author(s)
Richard G. Geyer
Accurate rf dielectric and magnetic characterization of ferrite ceramics requires combined measurement techniques.

Phase Relations of the SrO-Ho2O3-CuOx System

Author(s)
Winnie K. Wong-Ng, J Dillingham, Lawrence P. Cook
The phase diagram of the SrO-R 2O 3-CuOx system, where R=Ho, was investigated in air. The tie-line relationships of this system were determined. Two ternary

Ultracold Matter - Molecules at Rest

Author(s)
Carl J. Williams, Paul S. Julienne
In this issue (1), a group from the University of Texas reports producing rubidium dimers that are essentially at rest, by assembling them from ultracold Rb

Image Plates for Registration of Far-Ultraviolet Spectra

Author(s)
Joseph Reader, Craig J. Sansonetti, R Deslattes
We have tested an autoradiographic photostimulable phosphor image storage plate as a medium for recording spectra in the wavelength region from 50 to 550 and

Plasma Charge-Density Ratios in a Dusty Plasma

Author(s)
M A. Childs, Alan Gallagher
It is shown that particle diffusion in the afterglow of a dusty plasma can be used to establish several properties of the active plasma. Specifically, the ratio
