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

April 10, 2013
Author(s)
Siva K. Chinthalapati, Lee L. 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

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

Guidelines for Minimum Information for Publication of Quantitative Digital PCR Experiments

April 9, 2013
Author(s)
Ross J. Haynes, Jim Huggett, Carole Foy, Vladimir Benes, Kerry Emslie, Jeremy Garson, Jan Hellemans, Mikael Kubista, Tania Nolan, Michael Pfaffl, Gregory Shipley, Jo Vandesompele, Carl Wittwer, Stephen Bustin
There is growing interest in the digital polymerase chain reaction (dPCR) as technological progress makes it a practical and increasingly affordable technology. dPCR allows the precise quantification of nucleic acid, facilitating the measurement of small

Thermo-Mechanical Characterization of AuIn Transient Liquid Phase Bonding Die-Attach

April 9, 2013
Author(s)
Brian J. Grummel, Habib A. Mustain, Z. J. Shen, Allen R. Hefner Jr.
In next-generation wide-bandgap power electronics, the semiconductor device die-attach is of critical importance, for this transient liquid phase (TLP) bonding is a promising and effective die-attach technique. In this work, the thermal and mechanical

Critical Dimension small angel X-ray scattering measurements of FinFET and 3D memory structures

Regis J. Kline, Daniel F. Sunday, Chengqing C. Wang, Wen-Li Wu, Charlie Settens, Bunday Benjamin, Brad Thiel, Matyi Richard
Critical dimension small angle X-ray scattering (CD-SAXS) has been identified as a potential solution for measurement of nanoscale lithographic features by interrogating structures with sub-nanometer wavelength radiation in transmission geometry. The most

Estimating Uncertainties in Antenna Measurements

April 8, 2013
Author(s)
Michael H. Francis
We describe general methods of estimating uncertainties in antenna measurements. These include estimates based on theory (analysis1), simulation, and altering the measurement system (self-coparison tests). The important component sources of uncertainty in

Intercomparison between optical and x-ray scatterometry measurements of FinFET structures
