The National Vulnerability Database (NVD): Overview

December 18, 2013
Author(s)
Harold Booth, Doug Rike, Gregory A. Witte
The National Vulnerability Database (NVD), and its companion, the National Checklist Program (NCP), have provided a valuable and flexible set of services to users around the world since NVD was established in 2005. The NVD was established to provide a U.S

Does Your SEM Really Tell the Truth? - How would you know? Part 1

December 16, 2013
Author(s)
Michael T. Postek, Andras Vladar
The scanning electron microscope (SEM) has gone through a tremendous evolution to become a critical tool for many and diverse scientific and industrial applications. The high resolution of the SEM is especially suited for both qualitative and quantitative

Ionic Liquids Database - ILThermo (v2.0)

December 16, 2013
Author(s)
Andrei F. Kazakov, Joe W. Magee, Robert D. Chirico, Vladimir Diky, Kenneth G. Kroenlein, Chris D. Muzny, Michael D. Frenkel
ILThermo is a web-based ionic liquids database available free to the public. It aims to provide users worldwide with up-to-date information on publications of experimental investigation on ionic liquids, including numerical values of chemical and physical

Novel structural features in Candida albicans hyphal glucan provide a basis for differential innate immune recognition of hyphae versus yeast

December 16, 2013
Author(s)
Dan Bearden, Douglas W. Lowman, Rachel R. Greene, Michael D. Kruppa, Max Pottier, Mario Monteiro, David L. Williams
The innate immune system differentially recognizes Candida albicans yeast and hyphae. It is not clear how the innate immune system effectively discriminates between yeast and hyphal forms of C. albicans. Glucans are major components of the fungal cell wall

Mapping Trends in the Reorientational Mobilities of Tetrahydroborate Anions via Neutron-Scattering Fixed-Window Scans

December 15, 2013
Author(s)
Terrence J. Udovic, Kristina Verdal, John J. Rush, Daniel De Vries, Michael R. Hartman, John J. Vajo, Adam F. Gross, Alexander V. Skripov
The reorientational dynamics of BH 4 anions in a variety of environments of environments were measured as a function of temperature via fixed-window scans (FWSs) at zero energy transfer using a neutron backscattering spectrometer. The temperature

Mesoscale Inhomogeneities in Aqueous Solutions of Small Amphiphilic Molecules

December 15, 2013
Author(s)
Deepa Subramanian, Christopher T. Boughter, Jeffrey B. Klauda, Boualem Hammouda, Mikhail A. Anisimov
Small amphiphilic molecules, also known as hydrotropes, are too small to form equilibrium mesostructures, such as micelles, in aqueous solutions. However, aqueous solutions of nonionic hydrotropes may show the presence of a dynamic, loose, non-covalent

Sub-100 mK cooling using normal-metal?insulator?superconductor tunnel junctions

December 15, 2013
Author(s)
Peter J. Lowell, Galen C. O'Neil, Jason M. Underwood, Xiaohang NMN Zhang, Joel N. Ullom
Normal-metal∖insulator∖superconductor (NIS) junctions can be used as solid-state refrigerators since the hottest electrons preferentially tunnel from the normal metal into the superconductor. In this paper, we present NIS junctions optimized to cool

A comparison of methods for sketch-based 3D shape retrieval

December 13, 2013
Author(s)
Afzal A. Godil
Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. To foster this research area, two Shape Retrieval Contest (SHREC) tracks on this topic have been organized by us in 2012 and 2013 based on a small

First Report on Quantum Dot Coated CMOS CID Arrays for the UV and VUV

December 13, 2013
Author(s)
Uwe Arp, Robert E. Vest, Zoran Ninkov, Ross Robinson, Suraj Bhaskaran
A technique has been developed for coating commercial off the shelf (COTS) detector arrays with a thin, uniform layer of quantum dots. The quantum deposition is accomplished using an Optomec Aerosol Jet rapid prototyping system. When illuminated by UV

Quantification of Methane Source Locations and Emissions

December 13, 2013

Kuldeep Prasad(1), Brian Lamb(2), Maria Obiminda Cambaliza(3), Tegan Lavoie(3), Olivia E Salmon(3), Paul Shepson(3), Thomas Lauvaux(4), Ken Davis(4), and James R. Whetstone(1) (1) National Institute of Standards and Technology, Gaithersburg, MD. (2)

Semiconductor-based detectors

December 13, 2013
Author(s)
Sergio Cova, Massimo Ghioni, Mark A. Itzler, Joshua Bienfang, Alessandro Restelli
There is nowadays a widespread and growing interest in low-level light detection and imaging. This interest is driven by the need for high sensitivity in various scientific and industrial applications such as fluorescence spectroscopy in life and material

Understanding residual stress in electrodeposited Cu thin films

December 13, 2013
Author(s)
Eric Chason, Alison Engwal, Fei Pei, Manon C. Lafouresse, Ugo Bertocci, Gery R. Stafford, Joseph A. Murphy, Catherine Lenihan, D. N. Buckley
We report on the results of a multi-laboratory study to measure the steady state growth stress of planar copper thin films, electrodeposited from additive-free acidic sulfate electrolyte. Measurements were made using the wafer curvature method, that

Structure and Spectroscopy of Hydrogen Adsorbed in a Nickel Metal-Organic Framework

December 12, 2013
Author(s)
Craig M. Brown, Anibal Javier Ramirez-Cuesta, Jae-Hyuk Her, Paul S. Wheatley, Russell E. Morris
The structure of Ni 2(dobdc) (dobdc 4- = 2,5- dioxido-1,4-benzenedicarboxylate) as a function of deuterium adsorption has been determined through the application of in-situ neutron powder diffraction. Detailed information concerning the local adsorption

The role of the face and body in person identification

December 12, 2013
Author(s)
P J. Phillips, Rice Allyson, Alice O'Toole
Information useful for identifying a person can be found both in the face and body. Previous studies indicate that when an entire person is visible, we rely strongly on the face for identification, even if the body can be useful. In this study, we measured
