Monte Carlo studies of bootstrap variability in ROC analysis with data dependency

August 1, 2019
Author(s)
Jin Chu Wu, Alvin F. Martin, Raghu N. Kacker
ROC analysis involving two large datasets is an important method for analyzing statistics of interest for decision making of a classifier in many disciplines. And data dependency due to multiple use of the same subjects exists ubiquitously in order to

Nanoscale Magnetization Inhomogeneity within Single Phase Nanopillars

August 1, 2019
Author(s)
Thomas O. Farmer, Er-Jia Guo, Ryan D. Desautels, Lisa Debeer-Schmitt, Aiping Chen, Zhongchang Wang, Quanxi Jia, Julie Borchers, Dustin A. Gilbert, Ben Holladay, Sunil K. Sinha, Michael R. Fitzsimmons
We report observation of a radial dependence in the magnetic anisotropy of epitaxially strained CoFe 2O 4 nanostructures in a BaTiO 3 matrix. This archetypal example of a multiferroic heterostructure with a self-assembling three dimensional architecture

PHOTONIC THERMOMETRY: UPENDING 100 YEAR-OLD PARADIGM IN TEMPERATURE METROLOGY

August 1, 2019
Author(s)
Zeeshan Ahmed, Nikolai N. Klimov, Thomas P. Purdy, Tobias K. Herman, Kevin O. Douglass, Ryan P. Fitzgerald
For the past century, industrial temperature measurements have relied on resistance measurement of a thin metal wire or thin metal film whose resistance varies with temperature. Today’s resistance thermometers can routinely measure temperatures with

Reconciling LED and Monochromator-based Measurements of Spectral Responsivity

August 1, 2019
Author(s)
John F. Roller, Behrang H. Hamadani
The irradiance spectral responsivity is an important measurement characteristic for a reference solar cell and has served as a primary reference cell calibration method for a growing number of national labs in recent years. This paper discusses the process

The hunt for refrigerant blends to replace R-134a

August 1, 2019
Author(s)
Ian H. Bell, Piotr A. Domanski, Gregory T. Linteris, Mark O. McLinden
We investigated refrigerant blends as possible low GWP (global warming potential) alternatives for R-134a in an air-conditioning application. We carried out an extensive screening of the binary, ternary, and four-component blends possible among a list of

The Reproducibility of a Proposed Standard Fatigue Test for Cardiac Device Leads

August 1, 2019
Author(s)
Timothy P. Quinn, Jolene D. Splett, Joseph D. McColskey, James Dawson, David Smith, Adam Himes, Daniel Cooke
The Transvenous Cardiac Leads Working Group of the Cardiac Rhythm Management Devices Committee of The Association for the Advancement of Medical Instrumentation (AAMI CRMD WG1) is developing a fatigue performance standard for cardiac device leads. The

Tunable Multiferroic Order Parameters in Sr 1-x Ba x Mn 1-y Ti y O 3

August 1, 2019
Author(s)
Kamal Chapagain, Dennis E. Brown, Stanislaw Kolesnik, Saul Lapidus, Bianca Haberl, Jamie Molaison, Chuanlong Lin, Curtis Kenney-Benson, Changyong Park, Jaroslaw Pietosa, Ewa Markiewicz, Bartlomiej Andrzejewski, Jeffrey W. Lynn, Stephan Rosenkranz, Bogdan Dabrowski, Omar Chmaissem
Responding to the rapidly increasing demand for efficient energy usage and increased speed and functionality of electronic and spintronic devices, multiferroic oxides have recently emerged as key materials capable of tackling this multifacted challenge. In

1 GHz Waveform Synthesis with Josephson Arrays

July 31, 2019
Author(s)
Christine A. Donnelly, Justus A. Brevik, Nathan E. Flowers-Jacobs, Peter F. Hopkins, Paul D. Dresselhaus, Samuel P. Benz
For the first time, we synthesize single- and multiple-tone waveforms at gigahertz frequencies from arrays of Josephson junctions and demonstrate quantum-locked operation over a range of experimental input parameters. We first use a lumped-element circuit
