Semiempirical Configuration Interaction Calculations for RuCentered Dyes

February 18, 2018
Author(s)
Lisa A. Fredin, Thomas C. Allison
Computational investigation of of the photochemical properties of transition-metal-centered dyes typically involves optimization of the molecular structure followed by calculation of the UV/Visible spectrum. At present, these steps are usually carried out

Determining Mean Recurrence Intervals for Updated Wind Maps in ASCE 7-16

February 16, 2018
Author(s)
Therese P. McAllister, Naiyu Wang, Bruce Ellingwood
ASCE Standard 7 is moving toward load requirements that are consistent with reliability-based design goals characteristic of performance-based engineering (PBE). As part of this move, reliability analyses were conducted using updated wind data to determine

Examining Heat Treatment for Stabilization of the Lipidome

February 16, 2018
Author(s)
John Bowden, Candice Z. Ulmer, Christina Jones, Tracey Johnston, Jeremy P. Koelmel, Timothy J. Garrett, Richard A. Yost
Aim: To confidently determine lipid-based biomarkers, it is important to minimize variation introduced during preanalytical steps. We evaluated reducing variation associated with lipid measurements in invertebrate sentinel species using a state-of-the-art

Fractal Universality in Near-Threshold Magnetic Lanthanide Dimers

February 16, 2018
Author(s)
Eite Tiesinga, Constantinos Makrides, Ming Li, Svetlana Kotochigova
Ergodic quantum systems are often quite alike whereas non-ergodic, fractal systems are unique and display characteristic properties. In this paper we explore one of such fractal systems, weakly-bound dysprosium lanthanide molecules in an external magnetic

Application of Link Adaptation in Body Area Networks

February 15, 2018
Author(s)
Kamran Sayrafian, Martina Barbi, Mehdi Alasti
A Body Area Network (BAN) is a wireless protocol for connectivity of wearable and implantable sensors located inside, on the surface or near the human body. Medical applications requirements impose stringent constraints on the reliability, and quality of

Carbon Nanotube-Based Black Coatings

February 15, 2018
Author(s)
John H. Lehman, Christopher S. Yung, Nathan A. Tomlin, Davis R. Conklin, Michelle S. Stephens
It has been shown that coatings comprised of carbon nanotubes are very black; that is, characterized by low reflectance over a broad wavelength range from the visible to far infrared. Arguably there is no other material that is comparable. This is

Dietary Supplement Laboratory Quality Assurance Program: Exercise M Final Report

February 15, 2018
Author(s)
Melissa M. Phillips, Catherine A. Rimmer, Laura J. Wood, Maria R. Ale, Charles A. Barber, Hannah Stindt, Lee L. Yu
The NIST Dietary Supplement Laboratory Quality Assurance Program (DSQAP) was established in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS) in 2007 to enable members of the dietary supplements community to

Diffusion Monte Carlo versus adiabatic computation for local Hamiltonians

February 15, 2018
Author(s)
Stephen P. Jordan, Jacob Bringewatt, Alan Mink, William Dorland
Most research regarding quantum adiabatic optimization has focused on stoquastic Hamiltonians, whose ground states can be expressed with only real, nonnegative amplitudes. This raises the question of whether classical Monte Carlo algorithms can efficiently

Mixed Conductive Soft Solids by Electrostatically Driven Network Formation of a Conjugated Polyelectrolyte

February 15, 2018
Author(s)
Scott P. O. Danielsen, Gabriel E. Sanoja, Samantha R. McCuskey, Boualem Hammouda, Guillermo C. Bazan, Glenn H. Fredrickson, Rachel A. Segalman
The microscopic network structure transitions of a conjugated polyelectrolyte (Poly[2,6-(4,4-bis-potassium butanylsulfonate-4H-cyclopenta-[2,1-b;3,4-b']-dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)], CPE-K) hydrogel were explored with a combination of

Neutron Interferometry Detection of Early Crack Formation in Fatigued Additively Manufactured SS316 Dogbones

February 15, 2018
Author(s)
Daniel S. Hussey, Hong Yao, Adam J. Brooks, Ali Haghshenas, Jumao Yuan, Caroline G. Lowery, Jacob M. LaManna, David L. Jacobson, Nikolay Kardjilov, Shengmin Guo, Michael M. Khonsari, Leslie G. Butler
Fatigue in selective laser melted (SLM) and conventional SS316 dogbones was studied with neutron imaging methods for attenuation, scattering, and diffraction. To detect the microcrack evolution in fatigued samples,two methods of grating-based neutron

Computer Science in Education 2018

February 14, 2018
Author(s)
Jeff Voas, D. Richard Kuhn, Celia Paulsen, Kim B. Schaffer
We surveyed six of our profession's best senior computer science educators for their views on the current state and trends in computer science education.

The Technical Specification for the Security Content Automation Protocol (SCAP) Version 1.3

February 14, 2018
Author(s)
David A. Waltermire, Stephen D. Quinn, Harold Booth, Karen Scarfone, Dragos Prisaca
The Security Content Automation Protocol (SCAP) is a suite of specifications that standardize the format and nomenclature by which software flaw and security configuration information is communicated, both to machines and humans. This publication, along

Acid-induced and pH-controlled Reversible Switching of Broad-Spectrum Antibacterial Activity

February 13, 2018
Author(s)
Yin Y. Nelson, Vytautas Reipa, Xiaohong Wang, Kenneth Mineart, Vivek M. Prabhu, Nancy J. Lin, Jirun Sun
Bacterial resistance to antimicrobials is threatening millions of human lives due to indiscriminate overuse and environmental build-up of antibiotics. We present the smart regulation of antibacterial activity in biologically relevant conditions to reduce

Insertion of Dengue E into Lipid Bilayers Studied by Neutron Reflectivity Molecular Dynamics Simulations

February 13, 2018
Author(s)
Juan M. Vanegas, Frank Heinrich, David M. Rogers, Bryan D. Carson, Sadie La Bauve, Briana C. Vernon, Sushil K. Satija, Aihua Zheng, Margaret Kielian, Susan B. Rempe, Michael S. Kent
The envelope (E) protein of Dengue virus rearranges to a trimeric hairpin to mediate fusion of the viral and target membranes, which essential for infectivity. Insertion of E into the target membrane serves to anchor E and possibly also to disrupt local
