The OLES Imaging Metrology Program

November 22, 2006
Author(s)
Nicholas G. Paulter Jr.
The OLES Imaging Metrology Program is a broad-based interdisciplinary activity initiated and maintained for the development of metrology of digital imagery as applied to security, law enforcement, and corrections applications.

Drying Induced Variations in Physico-Chemical Properties of Amorphous Pharmaceuticals and Their Impact on Stability (I): Stability of aMonoclonal Antibody

November 21, 2006
Author(s)
Ahmad Abdul-Fattah, Vu Truong-Le, Luisa Yee, Lauren Nguyen, Devendra Kalonia, Marcus T. Cicerone, Michael Pikal
Both drying method and formulation had a significant impact on the properties of IgG1 powders, including storage stability. Among the drying methods, SSA was highest and perturbations in secondary structure were lowest with the spray dried preparations

Development of a Motion Imagery Quality Metric

November 20, 2006
Author(s)
J Irvine, Charles D. Fenimore, D Cannon, Donna Haverkamp, John W. Roberts, S Israel, L Simon, J Miller, A Aviles, Michelle Brennan
The motion imagery community would benefit from the availability of standard measures for assessing image interpretability. The National Imagery Interpretability Rating Scale (NIIRS) has served as a community standard for still imagery, but no comparable

Dynamic Lorentz Microscopy of Micromagnetic Structure in Magnetic Tunnel Junctions

November 20, 2006
Author(s)
Justin Shaw, R.H. Geiss, Stephen E. Russek
Lorentz microscopy was used to study the micromagnetic structure and magnetization reversal in magnetic tunnel junctions (MTJs) fabricated with different processing conditions including a preoxidation process. The authors find that the free layer in a MTJ

ECBCS Annex 47: Cost-Effective Commissioning Research

November 20, 2006
Author(s)
Natascha S. Milesi-Ferretti, Hannah Friedman, Marti Frank
In 2005, the Executive Committee of the International Energy Agency s (IEA) Energy Conservation in Buildings and Community Systems (ECBCS) program approved the start of a new four-year research project on building commissioning. Annex 47, on Cost-Effective

Metal-Insulator Transition Revisited for Cold Atoms in Non-Abelian Gauge Potentials

November 20, 2006
Author(s)
Indubala I. Satija, D C. Dakin, Charles W. Clark
We discuss the possibility of realizing metal-insulator transitions with ultracold atoms in two-dimensional optical lattices in the presence of artificial gauge potentials. Such transitions have been extensively studied for magnetic fields corresponding to

Summary of Latent Fingerprint work at NIST

November 20, 2006
Author(s)
Vladimir N. Dvornychenko, Michael D. Garris
This paper describes past and present fingerprint activity at NIST. While the primary focus is on latent fingerprints, the paper also surveys relevant general biometrics activity. The central focus of the paper is on the Latent Testing Workshop, held on

The Influence of NH 3 Anneal on the Crystallization Kinetics of HfO 2 Gate Dielectric Films

November 17, 2006
Author(s)
Patrick S. Lysaght, Joseph Woicik, Brendan Foran, Joel Barnett, Gennadi Bersuker, B H. Lee
HfO2 gate dielectric thin films have been exposed to anneal processing in NH3 and N2 ambient in order to decouple the influence of N incorporation from that of the thermal cycle alone. We report on the effectiveness of NH3 processing to introduce N into

INTEGRATED BRIDGE PROJECT DELIVERY AND LIFE CYCLE MANAGEMENT

November 16, 2006
Author(s)
Krishna Verma Verma, Thomas A. Siewert, F. Beckmann
This paper highlights developments that led the FHWA¿s Office of Bridge Technology, working with State departments of transportation (DOT) and the concrete and steel bridge industries, to launch a major initiative to identify available technologies and

Control of MEMS Nanopositioners With Nano-Scale Resolution

November 10, 2006
Author(s)
Jason J. Gorman, Yong Sik Kim, Nicholas Dagalakis
Several approaches for the precision control of micro-scale positioning mechanisms, or MEMS nanopositioners, are presented along with initial experimental results which demonstrate nano-scale positioning resolution. The MEMS nanopositioners discussed in

Microfluidic Method for Thermal Cycling by Microwave Dielectric Heating

November 9, 2006
Author(s)
Pierre-Alain Auroux, Jayna J. Shah, James Booth, Mulpuri Rao, Laurie E. Locascio, Michael Gaitan
We report on temperature time domain and spectral measurements for on-chip microwave thermocycling. In particular we observe enhanced specificity of the heating of a targeted sample compared to conventional heating block-based thermocyclers. Spatial

Photopatterned Polyelectrolyte Multilayers for Cell Culture

November 9, 2006
Author(s)
Darwin Reyes-Hernandez, J. Brian Hutchison, Laurie E. Locascio, Michael Gaitan
Patterned two-dimensional cell cultures are increasingly important for constructing bioanalytical tools for cell and molecular biology to address questions about interactions, signaling, migration, and differentiation, among others. This contribution

Low Magnetic Moment PIN Diodes for High Field MRI Surface Coils

November 8, 2006
Author(s)
Pavel Voskoboynik, Ronald D. Joos, W E. Doherty, Ronald B. Goldfarb
Positive-intrinsic-negative (PIN) silicon diodes are commonly used in magnetic resonance imaging (MRI) coils to perform active or passive blocking and detuning, or to disable circuit functions. However, diode packages with large magnetic moments are known

PEM Fuel Cell Membrane Hydration Measurement by Neutron Imaging

November 8, 2006
Author(s)
D J. Ludlow, M K. Jensen, C M. Calebrese, G A. Eisman, S Yu, C Dannehy, Daniel S. Hussey
Neutron scattering experiments on a proton exchange membrane fuel cell wereperformed to assess the ability to quantify water in the membrane and electrode/gas diffusion layers. Previous studies have shown that liquid water is easily resolved within flow

Cleaning of carbon nanotubes near the p-plasmon resonance

November 7, 2006
Author(s)
Katie Hurst, Darryl A. Keenan, John H. Lehman, Anne Dillon
The cleaning of bulk carbon single-walled nanotubes (SWNTs) by use of a 248 nm excimer laser is verified with imaging, and quantitative evaluation of morphology and composition. A 5% change in responsivity of a pyroelectric detector coated with SWNTs is

Perspectives on the quantum Zeno paradox

November 7, 2006
Author(s)
Wayne M. Itano
As of October 2006, there were approximately 535 citations to the seminal 1977 paper of Misra and Sudarshan which pointed out the quantum Zeno paradox (more often called the quantum Zeno effect). In simple terms, the quantum Zeno effect refers to a slowing
