Several new infrared absorption bands for 32S16O3 have been measured and analyzed. The principal bands observed were v1 + v2 (at 1561 cm-1), v1 + v4 (at 1594 cm-1, v3 + v4 at 1918 cm-1), and 3v3 (at 4136 cm-1). Except for 3v3, these bands are very

Artifacts in Ballistic Magnetoresistance Measurements

William F. Egelhoff Jr., L Gan, H Ettendgui, Y Kadmon, Cedric J. Powell, P J. Chen, Alexander J. Shapiro, Robert McMichael, J Mallett, Thomas P. Moffat, Mark D. Stiles
We have carried out an extensive search for credible evidence to support the existence of a ballistic magnetoresistance (BMR) effect in magnetic nanocontacts. We have investigated both thin-film and thin-wire geometries for both mechanically-formed and

John G. Gillen, Cynthia J. Zeissler, Christine M. Mahoney, Abigail P. Lindstrom, Robert A. Fletcher, P Chi, Jennifer R. Verkouteren, David S. Bright, R Lareau, M Boldman
Cluster primary ion bombardment combined with secondary ion imaging is used in an ion microscope secondary ion mass spectrometer for the spatially resolved analysis of organic particles on various surfaces. Compared to the use of monoatomic primary ion

Candidate Protocols for the HIMSS Registry Profile

June 1, 2004
Author(s)
William J. Majurski, J Barkely
The goal of this document is to help W3C editors write better specifications, by making a specification easier to interpret without ambiguity and clearer as to what is required in order to conform. It focuses on how to define and specify conformance. It

CCT Key Comparison No 1 (CCT-K1): Realisations of the ITS-90, 0.65 K to 24.5561 K, Using Rhodium-Iron Resistance Thermometers

A combinatorial library of Au/Ni metalizations on GaN were microstructurally characterized by x-ray diffraction (XRD), electron back-scattered diffraction (EBSD) and transmission electron microscopy (TEM). The array of single- and bi-layered metal elements

Comparative Measurements of Slovenian and USA Rockwell C Hardness Scales

June 1, 2004
Author(s)
A -. Stibler, Samuel Low, R -. Ellis
A national scale is set up for each hardness scale representing the reference hardness values in each country. From metrological and international trade aspects agreement between the national scales is very important. Good agreement makes possible good

Comparison of Fault Classes in Specification-Based Testing

June 1, 2004
Author(s)
Vadim Okun, Paul E. Black, Y Yesha
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

Cryogenic Transfer Line Chilldown
