We present measurements of cavity frequency pulling and collisional frequency shifts in a 87Rb fountain with a frequency resolution of 3 x 10 -16. Agreement...
solute rate coefficients for the reaction of C 2H with O 2 are measured at 90K by using a pulsed Laval nozzle apparatus with laser ionization, time-of-flight...

Using off-resonance Raman spectroscopy, we have examined each complex along the catalytic pathway of the DNA repair enzyme uracil DNA glycosylase (UDG). The...
Uracil DNA glycosylase (UDG) cleaves the glycosidic bond of deoxyuridine in DNA using a hydrolytic mechanism, with an overall catalytic rate enhancement of 10...
This manuscript is a short editorial comment to be published in Cytometry. The purpose of the comment is to bring to the attention of the flow cytometry...
This paper describes our initial efforts to deploy a digital library to support computer-aided collaborative design. At present, this experimental testbed, The...

Yttrium iron garnet (YIG) single-crystal fibers of nominal composition Y 3Fe 5O 12 were grown by the laser-heated pedestal growth technique, a miniaturized...
We have designed and evaluated an optical trap detector that is simple to fabricate and convenient to use. The trap geometry is a triangular tube similar to a...
Laser light scattering has been used to investigate particle formation in Fe(CO)5-inhibited premixed flames in order to understand the influence of metal and...

We describe the results of a comparison of optical-power meters undertaken by the National Institute of Standards and Technology (NIST, USA) and the...
We report on findings that the particle surface charge is influenced by solids concentration in aqueous suspensions of barium titanate. By combining results...
This article reports the results of time-resolved measurements of ion energy distributions (IEDs), relative ion densities, as well as optical emissions and...
The purpose of this document is to establish performance requirements and methods of test for active walk-through metal detectors used to find metal weapons and...
