ISODEC: Software for Calculating Diffraction Elastic Constants

June 1, 2012
Author(s)
Thomas H. Gnaeupel-Herold
A program is introduced that calculates diffraction elastic constants for the models according to Reuss, Hill, Kröner and inverse Kröner. For materials with preferred orientation it uses the orientation distribution function (ODF) to calculate the

Memristors with Flexible Electronic Applications

June 1, 2012
Author(s)
Nadine Gergel-Hackett, Joseph L. Tedesco, Curt A. Richter
In addition to the potential for memristors to be used in logic, memory, smart interconnects, and biologically-inspired architectures that could transform traditional silicon-based computing, memristors may enable such transformative technologies on

Nanoparticle Size and Shape Evaluation Using the TSOM Method

June 1, 2012
Author(s)
Bradley N. Damazo, Ravikiran Attota, Premsagar P. Kavuri, Andras Vladar
A novel through-focus scanning optical microscopy (TSOM) method that yields nanoscale information from optical images obtained at multiple focal planes will be used here for nanoparticle dimensional analysis. The TSOM method can distinguish not only size

On the need for an international effort to capture, share and use crystallisation screening data (failure and success)

June 1, 2012
Author(s)
David Gallagher, Janet Newman, Evan E. Bolton, Jochen M?Dieckmann, Vincent J. Fazio, David Lovell, Joseph R. Luft, Thomas S. Peat, David Ratcliffe, Roger A. Sayle, Edward H. Snell, Kerry Taylor, Pascal Vallotton, Sameer Velankar, Frank V. Delft
Crystallisation of biological macromolecules is seen by most structural biologists as a necessary evil, a means to the end, which is knowledge about a macromolecular structure. Crystallization remains largely a trial-and-error process, with extensive

Polarization-Analyzed Small-Angle Neutron Scattering. II. Mathematical Angular Analysis

June 1, 2012
Author(s)
Kathryn L. Krycka, Julie A. Borchers, Yumi Ijiri, Ryan Booth, Sara Majetich
SANS with longitudinal polarization analysis is a powerful technique to study magnetic morphology and domain interactions with directional sensitivity on the nancoscale. Here, by explicitly isolating the various nuclear-magnetic and magnetic-magnetic

Pulse Metrology, Part II

June 1, 2012
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson
Pulse metrology refers to the science of the measurement of pulses, which are transient phenomena. This article describes concepts important for pulse metrology, namely, reproducibility and repeatability of measurement, measurement uncertainty, and

Quantum Algorithms for Quantum Field Theories

June 1, 2012
Author(s)
Stephen P. Jordan, Keith S. Lee, John Preskill
Quantum field theory reconciles quantum mechanics and special relativity, and plays a central role in many areas of physics. We develop a quantum algorithm to compute relativistic scattering probabilities in a massive quantum field theory with quartic self

Role of Methyl Groups in Dynamics and Evolution of Biomolecules

June 1, 2012
Author(s)
Jonathan Nickels, Joseph E. Curtis, Hugh O'Neill, Alexei P. Sokolov
Early life was based on RNA and while RNA based catalytic molecules still function in biology to this day, studies have discovered a strong difference between dynamics of proteins and nucleic acids (DNA and RNA), especially at lower hydrations and low

SIM.EM-S5 Voltage, Current and Resistance Comparison

June 1, 2012
Author(s)
Harold Sanchez, Lucas Di Lillo, Gregory Kyriazis, Rodrigo Ramos, Randolph Elmquist, Nien F. Zhang
This paper reports the results of the second Interamerican Metrology System (SIM) comparison on calibration of digital multimeters, performed for strengthening the interaction among National Metrology Institutes (NMIs) and for establishing the degree of

Strain and Magnetic-Field Characterization of a Bronze-Route Nb 3 Sn ITER Wire: Benchmarking of Strain Measurement Facilities at NIST and University of Twente

June 1, 2012
Author(s)
Najib Cheggour, Arend Nijhuis, H J. Krooshoop, Xifeng Lu, Jolene D. Splett, Theodore C. Stauffer, Loren F. Goodrich, Matthew C. Jewell, Arnaud Devred, Y Nabara
A benchmarking experiment was conducted to compare strain measurement facilities at the National Institute of Standards and Technology (NIST) and the University of Twente. The critical current of a bronze-route Nb 3Sn wire, which was fabricated for the

Stray light correction algorithm for multi-spectral hyperspectral spectrographs

June 1, 2012
Author(s)
Michael Feinholz, Stephanie J. Flora, Steven W. Brown, Yuqin Zong, Keith R. Lykke, Mark A. Yarbrough, B. Carol Johnson, D. K. Clark
An algorithm is developed to correct a multi-channel fiber-coupled spectrograph for stray or scattered light within the system. The efficacy of the algorithm is evaluated based on a series of validation measurements of sources with different spectral
