Detection-Loophole-Free Test of Quantum Nonlocality, and Applications

September 26, 2013
Author(s)
B. G. Christensen, Kevin McCusker, Joseph Altepeter, Brice R. Calkins, Thomas Gerrits, Adriana Lita, Aaron J. Miller, Krister Shalm, Sae Woo Nam, P. G. Kwiat
We present a source of entangled photons that violates a Bell inequality free of the "fair-sampling" assumption, by over 50 standard deviations, and with enough "efficiency" overhead to eventually perform a fully loophole-free test of local realism. The

Determining Reference Test Weight per Bushel Value of Grains

September 26, 2013
Author(s)
Gloria D. Lee
Test weight per bushel is a measurement of the weight of a volume of grain required to fill level full a Winchester bushel measure of 2,150.42 cubic inches in capacity , which is equivalent to 32 quarts. Test weight per bushel is one of the measurements

Programmers Guide to the Air-Handling Unit Performance Assessment Rule DLL

September 26, 2013
Author(s)
Michael A. Galler
The AHU Performance Assessment Rules (APAR) were developed in 2001 and have been implemented as part of a limited number of Fault Detection and Diagnostics (FDD) tools. While a list of the rules has been widely available, an implementation of them that is

Structural Control of Magnetic Anisotropy in a Strain-Driven Multiferroic EuTiO 3 Thin Film

September 26, 2013
Author(s)
X. Ke, T. Birol, R. Misra, J.-H. Lee, Brian Kirby, D. G. Schlom, C.J. Fennie, J. W. Freeland
Octahedral distortion plays a key role in engineering physical properties of heterostructures of composed of perovskite oxides. We report on a strong in-plane uniaxial magnetic anisotropy in a strain-enabled multiferroic EuTiO 3 thin film epitaxially grown

10 TOhm and 100 TOhm High Resistance Measurements at NIST

September 25, 2013
Author(s)
Dean G. Jarrett, Marlin E. Kraft
The measurement techniques, standards, and bridges used to calibrate standard resistors in the 10 TΩ to 100TΩ range at NIST are described. Standard resistors, guarded Hamon transfer standard, and 10:1 and 100:1 bridge ratios, were used to provide multiple

Characterizing and Back-Porting Performance Improvement

September 25, 2013
Author(s)
Clif Flynt, Phil Brooks, Donald G. Porter
The Tcl interpreter is constantly being modified and improved. Improvements include new features and performance boosts. Everyone wants to use the latest releases with the newest improvements, but corporate users with large code bases may not be able to do

Co-Nonsolvency of Poly(n-isopropylacrylamide) in Deuterated Water/Ethanol Mixtures

September 25, 2013
Author(s)
Michael-Jon A Hore, Boualem Hammouda, Yuyan Li, He Cheng
Small-angle neutron scattering was used to investigate poly(N-isopropylacrylamide) (PNIPAM) polymer solutions in d-water /d-ethanol mixtures. A wide poor-solvent region was observed for mixtures near 60 % d-water/40 % d-ethanol mixture. Spinodal lines were

Rapid scan absorption spectroscopy using a waveform-driven electro-optic phase modulator in the 1.6- 1.65 ym region

September 25, 2013
Author(s)
Kevin O. Douglass, Stephen Maxwell, Gar W. Truong, Roger D. van Zee, Joseph T. Hodges, David Long, David F. Plusquellic
A method is reported for performing fast optical frequency scans over a bandwidth of 36.9 GHz and at a sweep rate of 40 kHz using a single second-order sideband from an electro-optic phase modulator driven by an arbitrary waveform generator. Single

The TREC Medical Records Track

September 25, 2013
Author(s)
Ellen M. Voorhees
The Text REtrieval Conference (TREC) is a series of annual workshops designed to build the infrastructure for large-scale evaluation of search systems and thus improve the state-of-the-art. Each workshop is organized around a set "tracks", challenge
