Force Distributions Near the Jamming and Glass Transitions

January 1, 2001
Author(s)
C S. O'Hern, Stephen A. Langer, A J. Liu, S R. Nagel
We measure the distributions of interparticle normal forces P(F) near the glass transition in supercooled liquids and near the jamming transition in foams and compare them to those obtained in recent experiments on static granular packings. We find that

Fundamental Constants and the Hydrogen Atom

January 1, 2001
Author(s)
Peter J. Mohr, Barry N. Taylor
A review is given of the latest adjustment of the values of the fundamental constants. The new values are recommended by the Committee on Data for Science and Technology (CODATA) for international use. Most of the fundamental constants are obtained by the

Fundamentals of Mass Spectrometry of Organic Compounds

January 1, 2001
Author(s)
Anzor I. Mikaia, Vladimir G. Zaikin, Alexey V. Varlamov, Nikolay A. Prostakov
The book is about mass spectrometry, design of instruments, theoretical aspects and methodological approaches, includes exercises. Portions of the book developed from lecture and laboratory material used presenting a course in organic mass spectrometry at

Future Voltage Metrology at NIST

January 1, 2001
Author(s)
Yi-hua D. Tang, June E. Sims, Michael H. Kelley
Presently NIST uses a voltage calibration path to maintain the U.S. legal volt and provide for the dissemination of an internationally consistent, accurate, reproducible and traceable voltage standard, tied to the SI units. Potential improvements and

Gene Expression Analysis on Medium-Density Oligonucleotide Arrays

January 1, 2001
Author(s)
R. Sinibaldi, C D. O'Connell, H Rodriguez, C. Seidel
As the human genome project continues toward its goal of sequencing the entire human genome by the end of 2003, this is providing unique opportunities for studying genetic variation in humans and its relationship with disease risk and aging. Consequently

Guest Editorial: Advances in Quantitative Image Analysis

January 1, 2001
Author(s)
Kevin J. Coakley, M Levenson
Kevin Coakley and Mark Levenson were invited to solicit papers on Quantitative Imaging for a special issue of the International Journal of Imaging Systems and TEchnology. They briefly describe the papers in a commentary that will appear in the special

Guide to Rheological Nomenclature: Measurement in Ceramic Particulate Systems

January 1, 2001
Author(s)
Vincent A. Hackley, Chiara F. Ferraris
This document provides definitions of terms and expressions relating to the measurement of rheological properties in liquid-based ceramic particulate systems (i.e., suspensions, pastes, and gels). The definitions are largely generic and should be
