NIST NCPDP Analysis - Suitability Assessment

August 31, 2011
Author(s)
Frank McKinney
This document completes the review of the NCPDP SCRIPT standard by reporting on several aspects related to its suitability as a standard to support Meaningful Use, including: completeness, correctness and internal consistency of the standard, ease of

Offset phase locking of noisy diode lasers aided by frequency division

August 31, 2011
Author(s)
Elizabeth A. Donley, Eugene N. Ivanov, Francois-Xavier R. Esnault
For heterodyne phase locking, frequency division of the beat note between two oscillators can improve the reliability of the phase lock and the quality of the phase synchronization. Frequency division can also reduce the size, weight, power, and cost of

Performance of New and Aged Residential Fire Sprinklers

August 31, 2011
Author(s)
Anthony D. Putorti Jr., William F. Guthrie, Jason D. Averill, Richard G. Gann
The U.S. Consumer Product Safety Commission (CPSC) initiated a program to determine the effects of emissions from problem drywall on residential electrical, gas distribution, and fire safety components. As part of this program, the National Institute of

Process Intermittent Measurement for Powder-Bed Based Additive Manufacturing

August 31, 2011
Author(s)
April L. Cooke, Shawn P. Moylan
Process intermittent measurements of parts fabricated by additive manufacturing (AM) can enable both in-process improvement and characterization of parts' internal geometries. The planar, layer-upon-layer nature of most AM processes allows simple two

Synthetic spike-in standards for RNA-seq experiments

August 31, 2011
Author(s)
Marc L. Salit, Lichun Jiang, Felix Schlesinger, Brian Oliver, Carrie Davis, Yu Zhang, Renhua Li, Thomas R. Gingeras
High-throughput sequencing of cDNA (RNA-seq) is a widely deployed transcriptome profiling and annotation technique, but questions about the performance of different protocols and platforms remain. We used a newly developed pool of 96 synthetic RNAs with

Testability Report for SCRIPT

August 31, 2011
Author(s)
Ioana Singureanu
This document summarizes the major testability issues raised by the NCPDP SCRIPT Implementation Guide Version 10.6. The ELR Implementation Guide is intended as a means of testing and certifying Electronic Health System (EHRS) for Meaningful Use.

Thermoelectric temperature control device for vapor pressure measurements

August 31, 2011
Author(s)
Robert F. Berg
The static method of measuring equilibrium vapor pressure requires locating the sample at the coldest part of the apparatus to avoid errors due to evaporation and recondensation elsewhere. This paper describes a device that can hold the sample 1 K below

TOWARDS INDUSTRIAL IMPLEMENTATION OF EMERGING SEMANTIC TECHNOLOGIES

August 31, 2011
Author(s)
Paul W. Witherell
In this paper, we identify five main obstacles in the development of an industry-ready application of semantic knowledge management systems and discuss how each of these challenges can be addressed. These obstacles include the ease of new knowledge

CHEMICAL INTERACTIONS OF THE Ba2YCu3O6+x SUPERCONDUCTOR WITH COATED CONDUCTOR BUFFER LAYERS

August 30, 2011
Author(s)
Winnie K. Wong-Ng, Zhi Yang, Guangyao Liu, Qingzhen Huang, Lawrence P. Cook, Shailee P. Diwanji, Christopher E. Lucas, Mi-Hye Jang, James A. Kaduk
Continued research on high Tc superconductors has led to the promise of a wide variety of industrial applications. To implement these applications, the availability of low-cost, long-length, and high-performance superconductor wire/tape and cable is

Magnetic field effects on large area avalanche photodiodes at cryogenic temperatures

August 30, 2011
Author(s)
Thomas R. Gentile, C. D. Bass, Jeffrey S. Nico, H Breuer, R Farrell
We present results for detection of X-rays by large area avalanche photodiodes (APDs) in strong magnetic fields and at cryogenic temperatures. Whereas at room temperature we observe essentially no effects on the response, at cryogenic temperature we

Nucleation and Growth of Freshly-Formed Particles from Limonene Ozonolysis

August 30, 2011
Author(s)
Chi P. Hoang, Dong H. Rim, Lance L. Wallace, Andrew K. Persily
In building environments, oxidation reactions involving ozone and terpenoids lead to nano-sized particle formation [Jang et al. 1999]. Low volatility products of these reactions are important and add to particle mass concentrations in air through

Ventilation Measurements in IAQ Studies: Problems and Opportunities

August 30, 2011
Author(s)
Andrew K. Persily, Hal Levin
Building and space ventilation rates are primary determinants of indoor pollutant levels and occupant exposures, and the impacts of ventilation on health and comfort have long been recognized in ventilation standards and regulations. Despite the importance

DIFFUSION-CONTROLLED REFERENCE MATERIAL FOR VOC EMISSIONS TESTING

August 29, 2011
Author(s)
Zhe Liu, Cynthia H. Reed, Steve Cox, John Little
To improve the reliability and accuracy of tests used to measure emissions of volatile organic compounds (VOCs) from samples of interior building products, the National Institute of Standards and Technology (NIST) and Virginia Tech (VT) have created a

Indoor Air Quality in Energy Efficient Buildings

August 29, 2011
Author(s)
Andrew K. Persily, Steven J. Emmerich
Building energy efficiency has been an important goal for decades. Since the energy crisis of the 1970s, much has been learned about how to improve energy efficiency in buildings. More recently, given increases in energy costs and concerns about the

Terahertz metrology and instrumentation

August 29, 2011
Author(s)
Erich N. Grossman, Zoya Popovic
This paper gives an overview of measurement techniques used in the THz region of the electromagnetic spectrum, from about 100 GHz to several THz. Currently available components necessary for THz metrology, such as sources, detectors and passives, are

The NIST EUV facility for advanced photoresist qualification using the witness-sample test

August 29, 2011
Author(s)
Steven E. Grantham, Charles S. Tarrio, Shannon B. Hill, Lee J. Richter, J. van Dijk, C. Kaya, N. Harned, R. Hoefnagels, M. Silova, J. Steinhoff
Before being used in an extreme-ultraviolet (EUV) scanner, photoresists must first be qualified to ensure that they will not excessively contaminate the scanner optics or other parts of the vacuum environment of the scanner. At the National Institute of
