Additional Section to PUB ID 918448. Combinatorial testing has rapidly gained favor among software testers in the past decade as improved algorithms have become available, and practical success has been demonstrated. This article reviews the theory and

EFFECT OF INSTALLATION FAULTS ON THE PERFORMANCE OF A SPLIT AIR CONDITIONER

August 18, 2015
Author(s)
Piotr A. Domanski, Hugh Henderson, William V. Payne
The study analyzed the effect of common installation faults on the cooling performance of a residential, split air conditioner installed in a single-family, slab-on-grade house. We considered five climatic regions in the United States from hot/humid to

Nanostructures and Dynamics of Macromolecules Bound to Attractive Filler Surfaces

August 18, 2015
Author(s)
Naisheng Jiang, Maya K. Endoh, Tadanori Koga, Tomomi Masui, Hiroyuki Kishimoto, Michihiro Nagao, Sushil K. Satija, Takashi Taniguchi
We report in-situ structures and dynamics of polybutadiene (PB) chains bound to carbon black (CB) fillers (the so-called "bound polymer layer (BPL)") in a good solvent. The BPL on the CB fillers were extracted by solvent leaching of a CB-filled PB compound

Performance of a dual Fabry-Perot cavity refractometer

August 18, 2015
Author(s)
Patrick F. Egan, Jack A. Stone Jr., Jay H. Hendricks, Jacob E. Ricker, Gregory E. Scace, Gregory F. Strouse
We have built and characterized a refractometer that utilizes two Fabry-Perot cavities formed on a dimensionally stable spacer. In the typical mode of operation, one cavity is held at vacuum and the other cavity is filled with nitrogen gas. The

svviz: a read viewer for validating structural variants

August 18, 2015
Author(s)
Noah Spies, Justin M. Zook, Marc L. Salit, Arend Sidow
We present svviz, a sequencing read visualizer for structural variants (SVs) that sorts and displays only reads relevant to a candidate SV. This is accomplished by searching input bam(s) for potentially relevant reads, realigning them against the inferred

Towards Repeatable, Reproducible, and Efficient Biometric Technology Evaluations

August 18, 2015
Author(s)
Gregory P. Fiumara, Wayne J. Salamon, Craig I. Watson
With the proliferation of biometric-based identity management solutions, biometric algorithms need to be tested now more than ever. Independent biometric technology evaluations are needed to perform this testing, but are not trivial to run, as demonstrated

Classification of Semiconducting Polymeric Mesophases to Optimize Device Post-Processing

August 17, 2015
Author(s)
Chad R. Snyder, Regis J. Kline, Dean M. DeLongchamp, Ryan C. Nieuwendaal, Lee J. Richter, Martin Heeney, Iain McCulloch
Semiconducting polymers form a variety of phases and mesophases that respond differently to post-deposition solvent or thermal treatments. Here it is shown that classification of these materials into their appropriate mesophases can be a useful tool to

Evaluation of two mitochondrial DNA biomarkers for prostate cancer detection

August 17, 2015
Author(s)
Samantha D. Maragh, Steven P. Lund
BACKGROUND: A 3.4kb deletion (3.4kbΔ) in mitochondrial DNA (mtDNA) found in histologically normal prostate biopsy specimens has been reported to be a biomarker for the increased probability of prostate cancer. Increased mtDNA copy number is also reported

Influence of Electron Doping on the Ground State of (Sr 1-x La x ) 2 IrO 4

August 17, 2015
Author(s)
Xiang Chen, Tom Hogan, D. Walkup, Wenwen Zhou, M. Pokharel, Mengliang Yao, Wei Tian, Thomas Z. Ward, Yang Zhao, Daniel E. Parshall, C. Opeil, Jeffrey W. Lynn, Vidya Madhavan, Stephen D. Wilson
The evolution of the electronic properties of electron-doped (Sr 1-xLa x) 2IrO 4 is experimentally explored as the solubility limit of La is approached. As electrons are introduced, the electronic ground state transitions from a spin-orbit Mott phase into

Proximity-Driven Enhanced Magnetic Order at Ferromagnetic-Insulator-Magnetic-Topological Insulator Interface

Using the Amplitude Variation of a Reverberation Chamber Channel to Predict the Synchronization of a Wireless Digital Communication Test System

August 16, 2015
Author(s)
Ray R. Tanuhardja, Luis A. Gonzalez, Chih-Ming Wang, William F. Young, Kate Remley
This contribution discusses the use of a metric based on the amplitude variation of a channel in the signal bandwidth to predict whether or not a digital wireless communication test system receiver will be able to demodulate a test signal. This metric is

In-Situ Method for Measuring the Mechanical Properties of Nafion Thin Films during Hydration Cycles

Perfluorinated ionomers, in particular Nafion, are an essential component in hydrogen fuel cells, as both the proton exchange membrane and the binder within the catalyst layer. During normal operation of a hydrogen fuel cell the ionomer will progressively

SOLAR-WIND ION DRIVEN X-RAY EMISSION FROM COMETARY AND PLANETARY ATMOSPHERES: MEASUREMENTS AND THEORETICAL PREDICTIONS OF CHARGE- EXCHANGE CROSS SECTIONS AND EMISSION SPECTRA FOR O6+ + H2O, CO, CO2, CH4, N2, NO, N2O, AND Ar
