Microsecond time-scale discrimination among polycytidylic acid, polyadenylic acid, and polyuridylic acid as homopolymers or as segments within single RNA molecules

December 1, 1999
Author(s)
M Akeson, D Branton, John J. Kasianowicz, E Brandin, D W. Deamer
Single molecules of DNA or RNA can be detected as they are driven through a single alpha-hemolysin channel by an applied electric field. During translocation, nucleotides within the polynucleotide must pass through the channel pore in sequential single

NIST Photometry and Colorimetry Facilities

December 1, 1999
Author(s)
Yoshihiro Ohno
Web site for public domain information and publications on NIST activities in photometry and colorimetry. Note: the copies of the NIST photometry papers are the final manuscripts and are not identical with the published versions in styles and editorial

Nose-to-Nose Response of a 20-GHz Sampling Circuit

December 1, 1999
Author(s)
Dylan F. Williams, Catherine A. Remley, Donald C. DeGroot
We use SPICE simulations to determine a response function of a two-diode 20-GHz sampling circuit. We explore the validity of the SPICE simulations in a variety of operational conditions and examine differences between the actual response of an impedance
