Nuclear magnetic resonance gyroscopes

April 15, 2013
Author(s)
Elizabeth A. Donley, John E. Kitching
This review begins with an introduction to NMR gyroscopes (NMRGs), followed by a discussion of the frequency shifts and relaxation mechanisms that determine and their performance. Specific NMRG implementations are then reviewed, including dual NMR species

SEISMIC FRAGILITY AND COST ANALYSES OF ACTIVELY CONTROLLED STRUCTURES

April 15, 2013
Author(s)
Kevin K. Wong, John L. Harris
Seismic fragility represents the probability that the structural response exceeds a given performance limit state due to a specified intensity of ground motion, and it has a direct relationship with the cost of rehabilitating the structural system. In this

Bell violation using entangled photons without the fair-sampling assumption

April 14, 2013
Author(s)
Marissa Giustina, Alexandra Mech, Sven Ramelow, Bernhard Wittman, Johannes Keffler, Joern Beyer, Adriana Lita, Thomas Gerrits, Sae Woo Nam, Rupert Ursin, Anton Zeilinger, Brice R. Calkins
The violation of a Bell inequality is an experimental observation that forces the abandonment of a local realistic viewpoint - namely, one in which physical properties are (probabilistically) defined before and independently of measurement, and in which no

Modeling and Simulation for Improving Ambulance Patient Compartment Design Standards

April 12, 2013
Author(s)
Deogratias Kibira, Yung-Tsun T. Lee, Allison Barnard Feeney, Jennifer L. Marshall, Larry Avery, Jennifer Moore, Carlotta Boone
Emergency medical service providers riding in ambulance patient compartments, while caring for patients, are at high risk of suffering injuries in case of a crash or sudden maneuver. Seat belts are one way to reduce the occurrence and severity of injuries

Reply to Comment on "Testing Three-body Quantum Electrodynamics with Trapped Ti20+ Ions: Evidence for a Z-Dependent Divergence between Experiment and Calculation"

April 12, 2013
Author(s)
Lawrence T. Hudson, C T. Chantler, M N. Kinnane, John D. Gillaspy, A.T. Payne, L F. Smale, Albert Henins, Joshua M. Pomeroy, J A. Kimpton, E Takacs, K Makonyi
We find that Epp’s [1] hypothesis - namely that the current experimental data set is well represented by a small constant or zero offset from the predictions of Artemyev et al. [2] - is not supported by standard statistical analysis. We find that adding

Block-copolymer healing of simple defects in a chemoepitaxial template

April 11, 2013
Author(s)
Paul N. Patrone, Gregg M. Gallatin
Using a phase-field model of block copolymers (BCPs), we characterize how a chemoepitaxial template with parallel lines of arbitrary width affects the BCP microdomain shape. The model, which is an extension of the Leibler-Ohta-Kawasaki theory, accounts for

Hospital Readmission by Method of Data Collection

April 11, 2013
Author(s)
Elizabeth M. Hechenbleikner, Martin A. Makary, Daniel Samarov, Jennifer L. Bennett, Susan L. Gearhart, Jonathan E. Efron, Elizabeth C. Wick
Hospital readmissions are increasingly used as a metric of quality with non-payment planned for excess preventable rehospitalizations. Currently, data for pay-for-performance incentives are obtained from administrative sources however this information may

Temperature Effect on the Nanostructure of SDS Micelles in Water

April 11, 2013
Author(s)
Boualem Hammouda
Sodium dodecyl sulfate (SDS) surfactants form micelles when dissolved in water. These are formed of a hydrocarbon core and hydrophilic ionic surface. The small-angle neutron scattering (SANS) technique was used with deuterated water (D 2O) in order to

A simple and sensitive HPLC-ICP-MS method for the accurate determination of Vitamin B12 in Fortified Breakfast Cereals and Multivitamin Tablet Reference Materials

April 10, 2013
Author(s)
Siva K. Chinthalapati, Lee Yu, John E. Schiel, Stephen E. Long
A sensitive high performance liquid chromatography (HPLC) coupled with inductively coupled plasma mass spectrometry (ICP-MS) method has been developed for the determination of vitamin B12. The method was based on efficient isocratic separation with a

Experimental Study of the Thermal Impacts on Wireless Sensor Batteries

April 10, 2013
Author(s)
Wenqi Guo, William M. Healy, Mengchu Zhou
Wireless sensor networks are being considered for application within buildings to control various equipment in different working environments. As wireless sensors are powered by commercially available batteries, battery performance will directly affect the

Gaps Analysis for CD Metrology Beyond the 22 nm Node

April 10, 2013
Author(s)
Benjamin D. Bunday, Thomas Germer, Victor H. Vartanian, Aaron Cordes, Aron Cepler, Charles Settens
This paper will examine the future for critical dimension (CD) metrology. First we will present the extensive list of applications for which CD metrology solutions are needed, showing commonalities and differences among the various applications. We will

Reducing noise in single-photon frequency conversion

April 10, 2013
Author(s)
Paulina S. Kuo, Jason S. Pelc, Oliver T. Slattery, Yong-Su Kim, Martin M. Fejer, Xiao Tang
We demonstrate low-noise and efficient frequency conversion using sum-frequency mixing in a periodically poled LiNbO3 (PPLN) waveguide. Using a 1556 nm pump, 1302 nm photons are efficiently converted to 709 nm photons. We obtain 70% conversion efficiency

Report on High-Rise Fireground Field Experiments

April 10, 2013
Author(s)
Jason D. Averill, Lori Moore-Merrell, Raymond T. Ranellone Jr., Craig G. Weinschenk, Nicole Taylor, Randy Goldstein, Robert Santos, Doug Wissoker, Kathy Notarianni, Kathryn Butler
In order to balance community expectations with limited resources, the fire service and community leaders require scientific data that quantifies the effects of changes in fire service deployment on the safety of the public and firefighters. This report

Active Transcriptomic and Proteomic Reprogramming in the C. elegans Nucleotide Excision Repair Mutant xpa-1

April 9, 2013
Author(s)
Katarzyna Arczewska, Gisele Tomazella, Jessica Lindvall, Henok Kassahun, Silvia Maglioni, Alessandro Torgovnick, Johan Henriksson, Olli Matilainen, Bryce J. Marquis, Bryant Nelson, Eshrat Babaie, Carina Holmberg, Thomas Burglin, Natascia Ventura, Bernd Thiede, Hilde Nilsen
Transcription-blocking oxidative DNA damage is believed to contribute to aging and to underlie activation of oxidative stress-responses and down-regulation of insulin-like signaling (ILS) in Nucleotide Excision Repair (NER) deficient mice. Here, we present

Dictionary Learning from Ambiguously Labeled Data

April 9, 2013
Author(s)
P J. Phillips, Yi-Chen Chen, Vishal M. Patel, Jaishanker K. Pillai, Rama Chellappa
We propose a novel dictionary-based learning method for ambiguously labeled multiclass classification, where each training sample has multiple labels and only one of them is the correct label. The dictionary learning problem is solved using an iterative
