Information Technology Laboratory Brochure

January 24, 2012
Author(s)
Elizabeth B. Lennon
This brochure describes the Information Technology Laboratory (ITL) at the National Institute of Standards and Technology, its mission, highlights, and research programs.

Efficiency of quasiparticle evacuation in superconducting devices

January 23, 2012
Author(s)
Sukumar Rajauria, L. Pascal, P. Gandit, F. Hekking, B. Pannetier, H. Courtois
We have studied the di®usion of excess quasiparticles in a current-biased superconductor strip in proximity to a metallic trap junction. In particular, we have measured accurately the superconductor temperature at a near-gap injection voltage. By analyzing

Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher

January 23, 2012
Author(s)
William C. Barker, Elaine B. Barker
This publication specifies the Triple Data Encryption Algorithm (TDEA), including its primary component cryptographic engine, the Data Encryption Algorithm (DEA). When implemented in an SP 800-38-series-compliant mode of operation and in a FIPS 140-2

Standards for the Optical Detection of Protein Particulates

January 23, 2012
Author(s)
Dean C. Ripple, Michael J. Carrier, Joshua R. Wayment
Particulates in protein therapeutics, composed of agglomerated protein monomers, may cause an immunogenic response in patients. Consequently, industry and the FDA desire more accurate methods for counting and characterizing particulates. Unlike likely

The Effects of Folding on High Strength Fibers Used in Soft Body Armor

January 23, 2012
Author(s)
Haruki Kobayashi, Walter G. McDonough, Joy Dunkers, Jae H. Kim, Hae-Jeong Lee, Scott Wight, Amanda L. Forster, Kirk D. Rice, Gale A. Holmes
Poly (p-phenylene benzobisoxazole) (PBO) fibers have been used in soft body armor (SBA) because of their high mechanical strength. However, there was an unexpected failure of a first responder's SBA which was composed of PBO fiber that was in service for

Ultrafast Demagnetization Measurements using Extreme Ultraviolet Light: Comparison of Electronic and Magnetic Contributions

January 23, 2012
Author(s)
Thomas J. Silva, Justin M. Shaw, Hans T. Nembach, Margaret M. Murnane, Henry C. Kapteyn, Chan La-O-Vorakiat, Stefan Mathias, Emrah Turgut, Teale A. Carson, Martin Aeschlimann, Claus M. Schneider
Ultrashort pulses of extreme ultraviolet light from high-harmonic generation are a new tool for probing coupled charge, spin, and phonon dynamics with element specificity, attosecond pump-probe synchronization, and time resolution of a few-femtoseconds in
