Stressing-Out DNA? The Contribution of Serine-Phosphodiester Interactions in Catalysis by Uracil DNA Glycosylase

October 17, 2000
Author(s)
R M. Werner, Y. L. Jiang, R. G. Gordley, J. Jagadeesh, Jane E. Ladner, G Xiao, M Tordova, G L. Gilliland, J T. Stivers
The DNA repair enzyme uracil DNA glycosylase (UDG) pinches the phosphodiester backbone of damaged DNA using the hydroxyl side chains of a conserved trio of serine residues, resulting in flipping of the deoxyuridine from the DNA helix into the enzyme active

Display Metrology Seminar

October 16, 2000
Author(s)
Eric Kelley
Display metrology is discussed as applied to flat panel displays (FPDs). Particular attention is given to display reflection measurements and how display reflection cannot be modeled in a simplistic way. Other topics include expected measurement

Exploring the Role of Polymer Melt Viscosity in Melt Flow and Flammability Behavior

October 15, 2000
Author(s)
Thomas J. Ohlemiller, John R. Shields, Kathryn M. Butler, Belinda L. Collins, Momar D. Seck
Thermoplastic polymers are widely used in roles where molding facilitates cost effective, high volume applications. Such polymers exhibit uniquely complex behavior in a fire because of their tendency to liquefy and flow. This behavior was explored in two

Plastic Microfluidic Devices Modified With Polyelectrolyte Multilayers

October 15, 2000
Author(s)
S L. Barker, Michael J. Tarlov, H E. Canavan, J J. Hickman, Laurie E. Locascio
Control of the polymer surface chemistry is a crucial aspect of development of plastic microfluidic devices. When commercially available plastic substrates are used to fabricate microchannels, differences in the EOF mobility from plastic to plastic can be

In-Flight Measurement of Thermal Spray Particle Temperatures Using Two-Color Optical Pyrometry

October 11, 2000
Author(s)
Frank S. Biancaniello, Steven P. Mates, Stephen D. Ridder, D Basak, D W. Bonnell, Jon C. Geist
Thermal spray is a materials processing technique used to deposit coatings to provide improved wear, corrosion, and/or thermal protection for engineering components. Thick (>10 {micro}m) thermal spray coatings are made up of individual solidified splats

Mastering and Archiving Uncompressed Digital Video Test Materials

October 11, 2000
Author(s)
Charles D. Fenimore
This is a report on the status of a Society of Motion Picture and Television Engineers (SMPTE) Ad Hoc Group charged with creating a master set of images for subjective testing of electronic systems. The images are to be sold at cost by SMPTE for use in the

NCT In-Situ Probes and the MBE Growth of Compound Semiconductors

October 11, 2000
Author(s)
Joseph G. Pellegrino, Jonathan E. Guyer, Donald A. Gajewski
Our research is centered on the use of in-situ measurement probes that monitor semiconductor growth. Our goal is to correlate material parameters observed during growth with device performance. A goal of this presentation is to develop collaborations that

Prokaryotic Expression, Purification, and Reconstitution of Biological Activities (Antiprotease, Antitumor and Heparin-Binding) for Tissue Factor Pathway Inhibitor- 2

October 5, 2000
Author(s)
C N. Rao, Prasad T. Reddy, D J. Reeder, Yonglin Liu, S M. Stack, W Kisiel, D T. Woodley
We report the expression of tissue factor pathway inhibitor-2 (TFPI-2) (also known as PP-5, placental protein-5; MSPI, matrix-associated serine protease inhibitor) in E. coli as a 25 kDa non-glycosylated protein with a glycine substituted for aspartic acid

Driven DNA Transport Into an Asymmetric Nanometer-Scale Pore

October 2, 2000
Author(s)
S. E. Henrickson, Martin Misakian, B Robertson, John J. Kasianowicz
To understand the mechanism by which individual DNA molecules partition into a nanometer-scale pore, we studied the concentration and voltage dependence of polynucleotide-induced current blockades of single a-hemolysin ionic channels. At fixed single

A Denial-of-Service Resistant Intrusion Detection Architecture

October 1, 2000
Author(s)
Peter M. Mell, D G. Marks, Mark McLarnon
As the capabilities of intrusion detection systems (IDS) advance, attackers may attempt to disable an organization's IDS before attempting to penetrate more valuable targets. As IDSs evolve into distributed systems withinterdependent components, they are

Accuracy Comparison of Absolute Optical Frequency Measurement Between Harmonic-Generation Synthesis and a Frequency-Division Femtosecond Comb

October 1, 2000
Author(s)
J Ye, T H. Yoon, John L. Hall, A A. Madej, J E. Bernard, K J. Siemsen, L Marmet
Using an iodine-stabilized He-Ne laser as a transfer oscillator, we compare absolute measurements of the optical frequency from a traditional frequency synthesis chain based on harmonic generation and from the frequency division technique of an ultrawide

Accurate Electrical Measurement of Coupled Lines on Lossy Silicon
