Confinement-Driven Increase in Ionomer Thin-Film Modulus

April 28, 2014
Author(s)
Kirt A. Page, Ahmet Kusoglu, Christopher M. Stafford, Sangcheol Kim, Regis J. Kline, Adam Weber
Ion-conductive polymers, or ionomers, are critical materials for a wide range of electrochemical technologies. For optimizing the complex, heterogeneous structures in which they occur, there is a need to elucidate the governing structure/function

Coordinate-space approach to vacuum polarization

April 28, 2014
Author(s)
Peter J. Mohr, P Indelicatio, J. Sapirstein
The vacuum-polarization correction for bound electrons or muons is examined. The objective is to formulate a framework for calculating the correction from bound-state quantum electrodynamics entirely in coordinate space, including the Uehling potential

CVSS Implementation Guidance

April 28, 2014
Author(s)
Joshua M. Franklin, Charles W. Wergin, Harold Booth
This Interagency Report provides guidance to individuals scoring vulnerabilities using the Common Vulnerability Scoring System (CVSS) Version 2.0 scoring metrics. CVSS defines a vulnerability as a bug, flaw, weakness, or exposure of an application, system

Direct generation of three-photon polarization entanglement

April 28, 2014
Author(s)
Deny Hamel, Krister Shalm, Hannes Hubel, Aaron J. Miller, Francesco F. Marsili, Varun Verma, Richard Mirin, Sae Woo Nam, Kevin Resch, Thomas Jennewein
Non-classical states of light are of fundamental importance for emerging quantum technologies. All optics experiments producing multi-qubit entangled states have until now relied on outcome post-selection, a procedure where only the measurement results

Quantum Algorithms for Fermionic Quantum Field Theories

April 28, 2014
Author(s)
Stephen P. Jordan, Keith S. Lee, John Preskill
Extending previous work on scalar field theories, we develop a quantum algorithm to compute relativistic scattering amplitudes in fermionic field theories, exemplified by the massive Gross-Neveu model. The algorithm introduces new techniques to meet the

Time-resolved double-slit interference pattern measurement with entangled photons

April 28, 2014
Author(s)
Lynden K. Shalm, Thomas Jennewein, Kevin Resch, Piotr Kolenderski, Carmelo Scarcella, Kelsey D. Johnsen Johnsen, Deny Hamel, Cahterine Holloway, Simone Tisa, Alberto Tosi
The double-slit experiment strikingly demonstrates the wave-particle duality of quantum objects. In this famous experiment, particles pass one-by-one through a pair of slits and are detected on a distant screen. A distinct wave-like pattern emerges after

Towards a Reference Architecture for Archival Systems: Use Case With Product Data

April 28, 2014
Author(s)
Raphael Barbau, Joshua Lubell, Sudarsan Rachuri, Sebti Foufou
Long-term preservation of product data is imperative for many organizations. A product data archive should be designed to ensure information accessibility and understanding over time. Approaches such as the Open Archival Information System (OAIS) Reference

A Model Towards Using Evidence from Security Events for Network Attack Analysis

April 27, 2014
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Constructing an efficient and accurate model from security events to determine an attack scenario for an enterprise network is challenging. In this paper, we discuss how to use evidence obtained from security events to construct an attack scenario and

Bilateral NMI Comparison of Guarded-Hot-Plate Apparatus

April 27, 2014
Author(s)
Alain Koenen, Robert R. Zarr, William F. Guthrie
Two national metrology laboratories (NMI) have conducted an international interlaboratory comparison on thermal conductivity on two thermal insulation reference materials. The Laboratoire national de métrologie et d'Essais (LNE) from France and the

Chapter 4: Fourier transform methods

April 25, 2014
Author(s)
Simon G. Kaplan, Manuel A. Quijada
Chapter 4 describes the use of Fourier Transform Spectrometers (FTS) for accurate spectrophotometry over a wide spectral range. After a brief exposition of the basic concepts of FTS operation, we discuss instrument designs and discuss their advantages and

NIST Micronutrients Measurement Quality Assurance Program Winter, Spring, and Fall 1995 Comparability Studies: Results for Round Robins XXXIII, XXXIV, and XXXV Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robins 7 and 8 Ascorbic Acid in H

April 25, 2014
Author(s)
David L. Duewer, Margaret C. Kline, Katherine E. Sharpless, Jeanice M. Brown Thomas, Sam A. Margolis
The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat- and water-soluble vitamins and carotenoids in human serum and plasma. This report describes

STEP File Analyzer User's Guide (Version 2)

April 25, 2014
Author(s)
Robert R. Lipman
This guide describes how to use the STEP File Analyzer, a software tool that generates a spreadsheet from a STEP (STandard for the Exchange of Product model data) file. The spreadsheets simplify inspecting information in the STEP file at an entity and

Electrodeposition of Al-W Alloys in the Lewis Acidic Aluminum Chloride-1-Ethyl-3-Methylimidazolium Chloride Ionic Liquid

April 24, 2014
Author(s)
Tetsuya Tsuda , Yuichi Ikeda , Takashi Arimura, Masaki Hirogaki, Akinito Imanishi, Susumu Kuwabata, Gery R. Stafford, Charles Hussey
The electrodeposition of non-equilibrium Al-W alloys was investigated in the Lewis acidic 66.7-33.3 % mole fraction aluminum chloride-1-ethyl-3-methylimidazolium chloride (AlCl_(3)-[EtMeIm]Cl) room-temperature ionic liquid (IL). The W(III) compound, K_(3)

Energy Levels And Spectral Lines Of Quadruply Ionized Iron (Fe V)

April 24, 2014
Author(s)
Alexander Kramida
This compilation revises and extends the previously recommended list of energy levels of quadruply ionized iron (Fe V) and provides a comprehensive list of observed spectral lines and transition probabilities in this spectrum. The new level optimization
