High resolution analysis of the nu1 and nu5 bands of phosgene 35Cl2CO and 35Cl37ClCO

March 2, 2015
Author(s)
Walter J. Lafferty, Jean-Marie Flaud, F. Kwabia Tchana, L. Manceron
Fourier transform spectra of phosgene (Cl2CO) have been recorded in the 11.75 μm and 5.47 μm spectral regions using a Bruker IFS125HR spectrometer at resolutions of 0.00102 cm-1 and 0.0015 cm-1 respectively leading to the observation of the ν5 and ν1

Structural Behavior of Li 2 B 10 H 10

March 2, 2015
Author(s)
Hui Wu, Wan Si NMN Tang, Vitalie Stavila, Wei Zhou, John J. Rush, Terrence J. Udovic
Based on x-ray and neutron powder diffraction, first-principles calculations, and neutron vibrational spectroscopy, Li 2B 10H 10 was found to exhibit atypical hexagonal-close-packed symmetry to best stabilize the ionic packing of the relatively small Li +

2D 1HN, 15N Correlated NMR Methods at Natural Abundance for Obtaining Structural Maps and Statistical Comparability of Monoclonal Antibodies

March 1, 2015
Author(s)
Luke Arbogast, Robert G. Brinson, Catherine A. Mouchahoir, James T. Hoopes, John Marino
Purpose High-resolution nuclear magnetic resonance spectroscopy (NMR) provides a robust approach for producing unique spectral signatures of protein higher order structure at atomic resolution. Such signatures can be used as a tool to establish consistency

Adiabatic optimization without local minima

March 1, 2015
Author(s)
Stephen P. Jordan, Michael Jarret
Several previous works have investigated the circumstances under which quantum adiabatic optimization algorithms can tunnel out of local energy minima that trap simulated annealing or other classical local search algorithms. Here we investigate the even

Coexistence of Superconductivity and Antiferromagnetism in (Li 0.8 Fe 0.2 ) OHFeSe

March 1, 2015
Author(s)
X. F. Lu, N. Z. Wang, Hui Wu, Y. P. Wu, D. Zhao, X. Z. Zeng, X. G. Luo, T. Wu, W. Bao, G. H. Zhang, F. Q. Huang, Qingzhen Huang, X. H. Chen
FeSe-derived superconductors show some unique behaviors relative to iron-pnictide superconductors, which are very helpful to understand the mechanism of superconductivity in high-T c iron-based superconductors. The low-energy electronic structure of the

Considerations for Design and In-Situ Calibration of High Accuracy Length Artifacts for Field Testing of Laser Trackers

March 1, 2015
Author(s)
Aaron Hudlemeyer, Daniel S. Sawyer, Christopher J. Blackburn, Vincent Lee, Mark Meuret, Craig M. Shakarji
Interim testing of laser trackers can be problematic due to the lack of high precision, long length artifacts that maintain their calibrated lengths during measurement. Gravitational loading, fixturing forces, and changes in the atmospheric conditions can

Fuzz Testing for Software Assurance

March 1, 2015
Author(s)
Vadim Okun, Elizabeth N. Fong
Fuzz Testing, or fuzzing, is a software testing technique that involves providing invalid, unexpected, or random test inputs to the software system under test. The system is then monitored for crashes and other undesirable behavior. Fuzz testing can be

Investigation of Surrogate Smoldering Ignition Sources for Testing Soft Furnishings

March 1, 2015
Author(s)
Richard G. Gann, Morgan Bruns, Amanda Robbins, Edward J. Hnetkovsky, Michael Ladas
The introduction of cigarette ignition propensity standards has led to a reduction in the availability of high ignition propensity commercial cigarettes. Since high ignition propensity cigarettes are needed for soft furnishing flammability tests, a

Mapping Monoclonal Antibody Structure by 2D 13C NMR at Natural Abundance

March 1, 2015
Author(s)
Luke Arbogast, Robert G. Brinson, John Marino
Monoclonal antibodies (mAbs) represent an important and rapidly growing class of biotherapeutics. Correct folding of a mAb is critical for drug efficacy, while misfolding can impact safety by eliciting unwanted immune or other off-target responses. Robust

Reference Diffraction Patterns, Microstructure, and Pore Size Distribution for the Copper (II) benzene-1,3,5-tricarboxylate Metal Organic Framework (Cu-BTC) Compounds

March 1, 2015
Author(s)
Winnie K. Wong-Ng, James A. Kaduk, Daniel W. Siderius, Andrew J. Allen, Laura Espinal, Brad Boyerinas, Igor Levin, Matthew Suchomel, Jan Ilavsky, Eric J. Cockayne, Hui Wu
Cu-paddle-wheel-based Cu3(BTC)2 (nicknamed Cu-BTC, where BTC ≡ benzene 1,3,5-tricarboxylate) is a metal organic framework (MOF) compound that adopts a zeolite topology. We have determined the pore size distribution using the Gelb and Gubbins technique, the
