Standard Reference Materials for Food Analysis

March 21, 2013
Author(s)
Melissa M. Phillips, Katherine E. Sharpless, Stephen A. Wise
Well-characterized reference materials with assigned concentrations of nutrients are needed as matrix-matched controls for analytical measurements to assist food manufacturers in quality control and facilitate compliance with nutritional labeling laws. The

Towards the Integration of Carbon Nanotubes as Vias in Monolithic 3D Integrated Circuits

March 21, 2013
Author(s)
Ann C. Chiaramonti Debay, Sten Vollebregt, Johan van der Cingel , Kees Beenakker, R. Ishihara
Carbon nanotubes (CNT) can be an attractive candidate for vertical interconnects (vias) in 3D integrated circuits due to their excellent thermal and electrical properties. To investigate CNT electrical resistivity, test vias were fabricated using both a

Arbitrary waveform generator for quantum information processing with trapped ions

March 20, 2013
Author(s)
Ryan S. Bowler, Ulrich J. Warring, Joseph W. Britton, J. M. Amini
Ions confined in a multi-electrode trap design have been proposed as a possible basis for quantum information processing. This scheme involves transporting ions between spatially distinct locations using time varying electric potentials combined with laser

Configuration of profiling tools for C/C++ applications under 64-bit Linux

March 20, 2013
Author(s)
David W. Flater
Application profiling tools are the instruments used to measure software performance at the function and application levels. Without careful configuration of the tools and the environment, invalid results are readily obtained. The errors may not become

Detection of E-cyanomethanimine (HCN-dimer) towards Sagittarius B2(N) from the GBT PRIMOS Survey

March 20, 2013
Author(s)
Francis J. Lovas, Daniel P. Zaleski, Nathan A. Seifert, Amanda L. Steber, Matt T. Muckle, Ryan A. Loomis, Joanna F. Corby, Oscar Martinez, Kyle Crabtree, Phillip R. Jewell, Jan M. Hollis, David Vasquez, Jolie Nyiramahirwe, Nicole Sciortino, Kennedy Johnson, Michael C. McCarthy, Anthony J. Remijan, Brooks H. Pate
An understanding of the formation, distribution and overall excitation of large molecules in astronomical environments remains in question even though more than 170 distinct chemical compounds have been detected in astronomical environments. Furthermore, a

Enhancing Electronic Health Record Usability in Pediatric Patient Care: A Scenario-Based Approach

March 20, 2013
Author(s)
Emily S. Patterson, Jiajie Zhang, Patricia Abbott, Michael C. Gibbons, Svetlana Z. Lowry, Matthew T. Quinn, Mala Ramaiah, David Brick
Adoption of electronic health record (EHR) systems in hospitals and physician practices is accelerating. Usability of EHRs has been identified as an important factor impacting patient safety and EHR adoption rate for both adult and pediatric care providers

A Semantic Framework for Systems Engineering Standards

March 19, 2013
Author(s)
Allison Barnard Feeney, David M. Price, Albert W. Jones
Systems engineers and asset managers create and maintain models of components and systems associated with long-lived, engineering assets. Component models come from many domains, disciplines and applications. System models typically require integration of

The Metrology of Counting Protein Particles

March 18, 2013
Author(s)
Dean C. Ripple, Michael J. Carrier, Richard E. Cavicchi, Christopher B. Montgomery, Zhishang Hu
A common degradation pathway for protein-based drugs is the growth of protein aggregates or particles. Counting and characterization of these particles is needed to assure the quality, efficacy, and safety of this type of drug. The unusual physical

The Federal Role in Cluster Formation

March 17, 2013
Author(s)
Gary W. Anderson Jr.
The answers to three related questions are critical to understanding the role of regional clusters as a key element of technology- based economic growth policy:  What drives cluster formation?  What are the economic impacts of clusters?  What policies

FACTORS INFLUENCING EXPOSURE TO ORGANOHALOGEN CONTAMINANTS IN PREDATORY BIRDS FROM COASTAL SOUTH CAROLINA, USA

March 15, 2013
Author(s)
Jessica L. Reiner, Jennifer Yordy, Sam Rossman, Peggy H. Ostrom, Stacy Hughes, Keely Bargnesi, James D. Elliot
Predatory bird species occupy high trophic levels and consequently are susceptible to bioaccumulating high levels of environmental contaminants. To evaluate potential risks from exposure to past- and current- use contaminants, levels of legacy contaminants
