NIST Micronutrients Measurement Quality Assurance Program Winter 2006 Comparability Studies: Results for Round Robin LIX Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 24 Ascorbic Acid in Human Serum

June 27, 2013
Author(s)
David L. Duewer, Jeanice M. Brown Thomas
The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat- and water-soluble vitamins and carotenoids in human serum and plasma. This report describes

Separation of variables in an asymmetric cyclidic coordinate system

June 27, 2013
Author(s)
Howard S. Cohl, Hans Volkmer
A global analysis is presented of solutions for Laplace's equation on three-dimensional Euclidean space in one of the most general orthogonal asymmetric confocal cyclidic coordinate system which admits solutions through separation of variables. We refer to

Standard Reference Materials for Medical CT

June 27, 2013
Author(s)
Zachary H. Levine, Huaiyu H. Chen-Mayer, Adam L. Pintar, Daniel S. Sawyer
NIST Standard Reference Materials 2087 and 2088 for medical computed tomography (CT) have become available. The materials allow CT reconstructions to be tied to the International System of Units in length, density, and mass attenuation coefficient.

On the Field Evaporation Behavior of c-axis GaN Nanowires in Laser-Pulsed Atom Probe Tomography

June 26, 2013
Author(s)
Matthew D. Brubaker, Kristine A. Bertness, Norman A. Sanford, Brian Gorman, David R. Diercks, R Kirchofer
GaN has seen use in many applications such as photovoltaics, blue and ultraviolet lasers, and light-emitting diodes with additional research into expanded and new applications. GaN in the form of nanowires present additional possibilities due to their high

The impact of turbulence on high accuracy time-frequency transfer across free space

June 26, 2013
Author(s)
Laura C. Sinclair, Fabrizio R. Giorgetta, William C. Swann, Esther Baumann, Ian R. Coddington, Nathan R. Newbury
Atmospheric optical path-length variations are measured across a 2-km optical link through a frequency comb-based system with femtosecond-level precision. Without mitigation, the turbulent piston effect will severely restrict time-frequency transfer from

Applications of Heat Transfer Fundamentals to Fire Modeling

June 25, 2013
Author(s)
Ofodike A. Ezekoye, M J. Hurley, Jose L. Torero, Kevin B. McGrattan
The fire industry relies on fire engineers and scientists to develop materials and technologies used to either resist, detect, or suppress fire. While combustion processes are the drivers for what might be considered to be fire phenomena, it is heat

Comparison and Analysis of Collisional-Radiative Models at the NLTE-7 Workshop

June 25, 2013
Author(s)
Yuri Ralchenko, H.-K. Chung, S Hansen, C. Bowen, C. J. Fontes
We present the main results of the 7th Non-Local Thermodynamic Equilibrium Code Comparison Workshop held in December 2011 in Vienna, Austria. More than twenty researchers from nine countries, who actively work on development of collisional-radiative codes

Forensic Science Laboratories: Handbook for Facility Planning, Design, Construction, and Relocation.

June 25, 2013
Author(s)
James Aguilar, Tom Barnes, Joseph Browne, Yvette Burney, John Byrd, Bonnie Carver, Adam Denmark, Susan Halla, Lou Hartman, Alison Kennedy, Deborah Leben, Greg Matheson, Jim McClaren, Russell McElroy, Romeo Miranda, Kenneth Mohr, Michael Mount, Steve Sigel, Jennifer Smither, Melissa Taylor, Aliece Watts, Shannan Williams
This handbook is a resource for laboratory directors, designers, consultants, and other stakeholders involved in the construction or major renovation of forensic science laboratories. Laboratory construction and renovation projects must meet the unique

The Challenge of Face Recognition From Digital Point-and-Shoot Cameras

June 25, 2013
Author(s)
P J. Phillips, J. R. Beveridge, David Bolme, Bruce A. Draper, Geof H. Givens, Yui M. Lui, Hao Zhang, W T. Scruggs, Kevin W. Bowyer, Patrick J. Flynn, Su L. Cheng
Face recognition is appearing in personal and commercial products at an astonishing rate, yet reliable face recognition remains challenging. Users expect a lot; they want to snap pictures and have their friends, family and acquaintances recognized. This
