Dimensional Reduction of Duplex DNA Under Nanofluidic Slit Confinement

August 19, 2015
Author(s)
Luis Fernando Vargas Lara, Jack F. Douglas, Samuel M. Stavis, Elizabeth A. Strychalski, Jon C. Geist, Brian J. Nablo
There has been much recent interest in the dimensional properties of duplex DNA under nanoscale confinement conditions as a problem of fundamental interest in both technological and biological fields. This has led to a series of measurements by

Hitting the bounds of chemistry: Limits and tradeoffs for low-GWP refrigerants.

August 19, 2015
Author(s)
Mark O. McLinden, J. Steven Brown, Andrei F. Kazakov, Piotr A. Domanski
We explore the possibilities for low-GWP refrigerants through two approaches. First, we explore the performance of hypothetical refrigerants to define the limits of what is allowed by thermodynamics. In the second approach, we apply property estimation

Improved electronic measurement of the Boltzmann constant by Johnson noise Thermometry

Author(s)
Weston L. Tew, Samuel P. Benz, Horst Rogalla, Alessio Pollarolo, David R. White, Jifeng Qu, Kunli Zhou
The unit of thermodynamic temperature, the kelvin, will be redefined in 2018 by fixing the value of the Boltzmann constant, k. The present CODATA recommended value of k is determined predominantly by acoustic gas-thermometry results. To provide a value of

Test of a virtual cylindrical acoustic resonator for determining the Boltzmann constant

August 19, 2015
Author(s)
XiaoJuan Feng, Hong Lin, Keith A. Gillis, Michael R. Moldover, Jintao Zhang
We report progress in determining the Boltzmann constant k B using a virtual acoustic resonator derived by combining the measured frequencies of the longitudinal acoustic modes of two argon-filled, cylindrical, cavity resonators in such a way as to

A compact optically coherent fiber frequency comb

August 18, 2015
Author(s)
Laura C. Sinclair, Jean-Daniel Deschenes, Lindsay I. Sonderhouse, William C. Swann, Isaac H. Khader, Esther Baumann, Nathan R. Newbury, Ian R. Coddington
We describe design and operation of a robust self-referenced, optically coherent frequency comb. The system robustness is derived from a combination of an optics package based on polarization-maintaining fiber, high signal-to-noise ratio (SNR) detection of

Combinatorial Testing: Theory and Practice

David R. Kuhn, Renee Bryce, Feng Duan, Laleh Ghandehari, Yu Lei, Raghu N. Kacker
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 application of this method, focusing

Combinatorial Testing: Theory and Practice, Section 8.

August 18, 2015
Author(s)
David R. Kuhn, Renee Bryce, Feng Duan, Laleh Ghandehari, Yu Lei, Raghu N. Kacker
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
