Absolute measurements of x-ray backlighter sources at energies above 10 keVa)

February 1, 2012
Author(s)
Lawrence T. Hudson, B.R. Maddox, H.S. Parks, B A. Remington, C. Chen, S Chen, S. T. Prisbrey, A. Comley, C A. Back, C. Szabo, John F. Seely, Uri Feldman, Stephen M. Seltzer, M. J. Haugh, Z. Ali
Line emission and broadband x-ray sources with x-ray energies above 10 keV have been investigated using a range of calibrated x-ray detectors for use as x-ray backlighters in high energy density (HED) experiments. The conversion efficiency of short- and

Building Security into Off-the-Shelf Smartphones

February 1, 2012
Author(s)
Angelos Stavrou, Jeff Voas, Tom T. Karygiannis, Stephen Quirolgico
Recent advancements in hardware have increased the computing power, memory, storage, and wireless connectivity of handheld mobile devices. Smart-phone devices are used for everyday activities that range from Maps and Geo-location tagging to banking. Indeed

Dispersion-Strengthened Silver Alumina for Sheathing Bi2Sr2CaCu2O8+x Multifilamentary Wire

February 1, 2012
Author(s)
Amir Kajbafvala, William Nachtrab, Xifeng Lu, Frank Hunte, Xiaotao Liu, Najib Cheggour, Terence Wong, Justin Schwartz
High strength, high modulus dispersion strengthened (DS) silver-aluminum alloys are studied for sheathing Bi 2Sr 2CaCu 2O8 +x (Bi2212) round wire. Dispersion strengthening is an effective method for producing a fine grain metallurgical structure that is

Hyperspectral Imaging of Ischemic Wounds

February 1, 2012
Author(s)
David W. Allen
Optical imaging has the potential to achieve high spatial resolution and high functional sensitivity in wound assessment. However, clinical acceptance of many optical imaging devices is hampered by poor reproducibility, low accuracy, and lack of biological

Molecular Insights into a-Synuclein and Its N-terminal Peptides at the Membrane Interface

February 1, 2012
Author(s)
Candace M. Pfefferkorn, Frank Heinrich, Alexander J. Sodt, Alexander S. Malstev, Richard W. Pastor, Jennifer C. Lee
The role of phospholipids in modulating α-synuclein (α-syn) conformation is of great interest because α-syn aggregation is linked to Parkinson¿s disease. Using a sparsely tethered-bilayer composed of 1:1 molar ratio of 1-palmitoyl-2-oleoyl-sn-glycero-3

Numerical Study of the Thermodynamics of Clinoatacamite

February 1, 2012
Author(s)
Ehsan Khatami, Joel Helton, Marcos Rigol
In this Brief Report, we discuss the use of linked-cluster expansions in solving quantum models that break certain symmetries of the underlying lattice. We sketch the algorithm for the numerical linked-cluster expansions (NLCEs) and show that although some

OASIS Collaborative Energy Standards, Facilities, and ZigBee Smart Energy

February 1, 2012
Author(s)
David G. Holmberg, William Cox, Don Sturek
The enterprise integration-style interfaces and information models in the Organization for the Advancement of Structured Information Systems (OASIS) collaborative energy standards are designed to address information exchange across the smart grid. This

Polymer Dynamics in Constrained Geometries

February 1, 2012
Author(s)
Christopher Soles, Ryan Nieuwendaal, Huagen H. Peng
The wide-spread interest in the dynamical property of organic materials under strong states of confinement largely began with differential scanning calorimeter (DSC) measurements in the early 90's of the glass transition and heat capacity of glass forming

Resonant control of polar molecules in an optical lattice

February 1, 2012
Author(s)
Thomas M. Hanna, Eite Tiesinga, William F. Mitchell, Paul S. Julienne
We study the resonant control of two nonreactive polar molecules in an optical lattice site, focussing on the example of RbCs. Collisional control can be achieved by tuning bound states of the intermolecular dipolar potential, by varying the applied
