Methodological Challenges in Including Green Tea Dietary Supplements to Analytically Verified Databases.

April 1, 2015
Author(s)
Catherine Rimmer, Leila Saldanha, Johanna Dwyer, Karen Andrews, Regan Bailey, Joseph Betz, Vicki Burt, Rebecca Costello, Nancy Emenaker, Jaime Gahche, J. Harnly, Constance Hardy, Pamela R. Pehrsson
Dietary supplement databases are needed to calculate total dietary intakes from foods and supplements. Analytically verified databases are necessary for commonly consumed products as estimates of intakes are used in guiding public policy decisions. The

NGD Cold Neutron Prompt Gamma-ray Activation Analysis Spectrometer at NIST

April 1, 2015
Author(s)
Rick L. Paul, Dagistan NMN Sahin, Jeremy C. Cook, Christoph W. Brocker, Richard M. Lindstrom, Donna J. O'Kelly
A new instrument for cold neutron prompt gamma-ray activation analysis (CNPGAA) has been designed and constructed as part of the recent expansion of the cold neutron guide hall at the NIST Center for Neutron Research (NCNR). Located on neutron guide NGD

Perfluorinated Alkyl Acids in Abiotic Standard Reference Materials

April 1, 2015
Author(s)
Jessica L. Reiner, Jennifer M. Lynch, Andrea Blaine, Christopher Higgins, Carin Huset, Thomas Jenkins, Christiaan Kwadijk, Cleston Lange, Derek Muir, William K. Reagen, Courtney Rich, Jeff Small, Mark J. Strynar, John Washington, Hoon Yoo
The National Institute of Standards and Technology (NIST) has a wide range of Standard Reference Materials (SRMs) which have values assigned for legacy organic pollutants and toxic elements. Existing SRMs serve as homogenous materials that can be used for

Sub-visible (2 mm to 100 mm) particle analysis during biotherapeutic drug product development: Part 1, considerations and strategy

April 1, 2015
Author(s)
Dean C. Ripple, Linda Narhi, Natliya Afonina, Satish Singh, Andrea Herre, Patrick Garidel, Atanas Koulov, Vincent Corvari, Thomas Spitznagel, Paolo Mangiagalli, Irene Cecchini, Klaus Wuchner, Tony Lubiniecki, Hanns-Christian Mahler, Roland Schmidt, Alla Polozova, Patricia Cash, Andrew Weiskopf, Douglas Nesta, Mara Rossi, Robert Simler
Measurement and characterization of particles in the 1 µm to 100 µm range (sub-visible particles), including protein aggregates, is an important part of every stage of protein therapeutic development. The tools used and the ways in which the information

The role of standards in MEMS commercialization

April 1, 2015
Author(s)
Michael Gaitan
For many years, the development, creation and use of standards has played a valuable role in the successful commercialization of products, services and processes that address many industries and many applications. So it is with microelectromechanical

Combinatorial Coverage as an Aspect of Test Quality

March 31, 2015
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
There are relatively few good methods for evaluating test set quality, after ensuring basic requirements traceability. Structural coverage, mutation testing, and related methods can be used if source code is available, but these approaches may entail

First measurements of the flux integral with the new NIST-4 watt balance

March 31, 2015
Author(s)
Darine El Haddad, Frank Seifert, Leon Chao, Yusi A. Cao, Georgio A. Sineriz, Jon R. Pratt, David B. Newell, Stephan Schlamminger
In early 2014, construction of a new watt balance, named NIST-4, has started at the National Institute of Standards and Technology (NIST). In a watt balance, similar to a mass comparator, the gravitational force of an unknown mass is compensated by an

Fractional Quantum Hall States of Rydberg Polaritons

March 31, 2015
Author(s)
Mohammad F. Maghrebi, Norman Y. Yao, Mohammad Hafezi, Thomas Pohl, Ofer Firstenberg, Alexey Gorshkov
We propose a scheme for realizing fractional quantum Hall states of light. In our scheme, photons of two polarizations are coupled to Rydberg atoms via auxiliary classical control fields to form two flavors of Rydberg polaritons, effective spin up and spin

Risk-Informed Performance-Based Design Concepts and Framework

March 31, 2015
Author(s)
Brian J. Meacham, Alberto Alvarez-Rodriguez
A new framework for a risk-informed performance-based approach to fire safety analysis and design has been proposed. It is structured around a paradigm in which the performance analysis is conducted relative to the performance of a building-occupant system

Considerations for Identity Management in Public Safety Networks

March 30, 2015
Author(s)
Nelson Hastings, Joshua M. Franklin
This document analyzes approaches to identity management for public safety networks in an effort to assist individuals developing technical and policy requirements for public safety use. These considerations are scoped into the context of their
