Author(s)
Patrick D. O'Reilly
This annual report covers the work conducted within the National Institute of Standards and Technology's Computer Security Division during Fiscal Year 2010. It discusses all projects and programs within the Division, staff highlights, and publications.

Healthcare Information Technology Standards: General Suitability Analysis

May 31, 2011
Author(s)
Liora Alschuler
The methodology described in this document was produced and developed by Lantana Consulting Group for the National Institute of Standards and Technology (NIST). It is part of a series of suitability analsyses on four healthcare standards performed under

Templated CDA:Key Concept for Interoperability

May 31, 2011
Author(s)
Liora Alschuler
This document supplements information about “templated CDA” in the context of the Healthcare Information Technology (HIT) Standards Analysis Project carried out by Lantana Consulting Group for the National Institute of Standards and Technology (NIST).

Mimicking Biological Design & Computing Principles in Artificial Olfaction

May 27, 2011
Author(s)
Baranidharan Raman, Stephen Semancik
Biology has been an inspiration for designing solutions to many engineering problems including chemical sensing. Modern approaches to chemical sensing have been based on the biological principle of combining cross-selective chemical sensors with a pattern

A Traceable Scatterometry Measurement of a Silicon Line Grating

May 26, 2011
Author(s)
Thomas A. Germer, Heather J. Patrick, Ronald G. Dixson
In this paper, we present a spectroscopic Mueller matrix ellipsometry measurement of a silicon line grating with nominal pitch of 600 nm and line width 100 nm. An uncertainty analysis is performed on the measurement results. The results are compared to

Effects of JPEG 2000 Image Compression on 1000ppi Fingerprint Imagery

May 26, 2011
Author(s)
Shahram Orandi, John M. Libert, John Grantham, Kenneth Ko, Stephen S. Wood, Jin Chu Wu
This paper presents the findings of a study conducted to measure the impact of JPEG 2000 compression on fingerprint imagery at various levels of compression. The impact of compression is measured in terms of impact to both Galton and non-Galton based

Effects of Roughness on Scatterometry Signatures

May 26, 2011
Author(s)
Martin Foldyna, Thomas Germer, Brent Bergner
We used azimuthally-resolved spectroscopic Mueller matrix ellipsometry to study a periodic silicon line structure with and without artificially-generated line edge roughness (LER). Grating profiles were determined from multiple azimuthal configurations

High-Resolution Passive Video-Rate Imaging at 350 GHz

May 26, 2011
Author(s)
Daniel T. Becker
We are developing a 350 GHz cryogenic passive video imaging system for use in standoff security applications. This demonstration system uses 800 photon-noise-limited superconducting transition edge sensor bolometers, read out using a time-division

Microwave Characterization of Transparent Conducting Films

May 26, 2011
Author(s)
Jan Obrzut, Oleg A. Kirillov
The high frequency conductivity of thin metallic and graphitic nano-films attracts interest due to many potential applications in spin electronics, electromagnetic shielding, flexible antennas, displays, and solar cells. The surface morphology of thin

The Effect of Folding on the Internal Structure of Ballistic Fibers

May 26, 2011
Author(s)
Haruki Kobayashi, Walter G. McDonough, Hae-Jeong Lee, Jae H. Kim, Amanda L. Forster, Kirk D. Rice, Gale A. Holmes
In one of our previous studies, the mechanical properties of poly (p-phenylene benzobisoxazole) (PBO) fibers were degraded when the fibers were folded. When we examined poly (p-phenylene terephthalamide) (PPTA) fibers, we did not find a similar drop in

Anemia, Hypothyroidism and Immune Suppression Associated with Polychlorinated Biphenyl Exposure in Bottlenose Dolphins (Tursiops truncatus)

May 25, 2011
Author(s)
John Kucklick, Lori Schwacke, Eric Zolman, Brian C. Balmer, Sylvain De Guise, Clay George, Jennifer Hoguet, Steve Lamb, Milton Levin, J. L. Litz, W E. McFee, Ned Place, Forrest Townsend, Teresa Rowles, Randall Wells, Aleta Hohn
Background: Polychlorinated biphenyls (PCBs) and other legacy organohalogens are often monitored in marine mammals both to understand health risks for populations of these protected species and as an indication of marine food web contamination. Bottlenose

Fluid interactions with metafilm/metasurfaces for tuning, sensing, and microwave assisted chemical processes

May 25, 2011
Author(s)
Joshua A. Gordon, Christopher L. Holloway, James C. Booth, James R. Baker-Jarvis, David R. Novotny, Sung Kim, Yu Y. Wang
In this paper we demonstrate tunability of a metafilm, which is the two-dimensional equivalent of a metamaterial, also referred to as a metasurface, by changing the permittivity in a micro-fluidic channel that interacts with the metafilm. Numerical

Redox-Promoting Protein Motions in Rubredoxin

May 24, 2011
Author(s)
Jose M. Borreguero, Junhong He, F. Meilleur, Kevin Weiss, Craig Brown, D. A. A. Myles, Kenneth W. Herwig, Pratul K. Agarwal
Abstract Proteins are dynamic objects, constantly undergoing conformational fluctuations, yet the linkage between internal protein motion and function is widely debated. This manuscript reports on the characterization of temperature-activated collective
