Hotspot Relaxation Dynamics in a Current Carrying Superconductor

March 17, 2016
Author(s)
Francesco Marsili, Martin Stevens, Alex Kozorezov, Varun Verma, Colin Lambert, Jeffrey A. Stern, Rob Horansky, Shellee D. Dyer, Shannon Duff, David P. Pappas, Matthew Shaw, Richard Mirin, Sae Woo Nam
When a photon is absorbed in a superconductor it creates a region of nonequilibrium superconductivity referred to as a hotspot [1]. The operation of most superconducting single photon detectors (microwave kinetic inductance detectors, MKIDs [2,3]

Anomalous broadening in driven dissipative Rydberg systems

March 16, 2016
Author(s)
Elizabeth A. Goldschmidt, Thomas L. Boulier, Roger C. Brown, Silvio B. Koller, Jeremy T. Young, Alexey V. Gorshkov, S L. Rolston, James V. Porto
We observe interaction-induced broadening of the two-photon 5s-18s transition in 87Rb atoms trapped in a 3D optical lattice. The measured linewidth increases by nearly two orders of magnitude with increasing atomic density and excitation strength, with

Predicting Structures of Ru-Centered Dyes: A Computational Screening Tool

March 16, 2016
Author(s)
Lisa A. Fredin, Thomas C. Allison
Dye-sensitized solar cells (DSCs) represent a viable means for harvesting solar energy to produce electrical power. Though a number of light harvesting dyes are in use, the search continues for more efficient and effective compounds to make commercially

Stochastic behavior of nanoscale dielectric wall buckling

March 16, 2016
Author(s)
Lawrence H. Friedman, Igor Levin, Robert F. Cook
The random buckling patterns of nanoscale dielectric walls are analyzed using a nonlinear multi-scale stochastic method that combines experimental measurements with simulations. The dielectric walls, approximately 200 nm tall and 20 nm wide, consist of

A Bacteriophage Endolysin that Eliminates Intracellular Streptococci

March 15, 2016
Author(s)
Yang Shen, Marilia Barros, Tarek Vennemann, David Travis Gallagher, Yizhou Yin, Sara B. Linden, Ryan D. Heselpoth, Dennis J. Spencer, David M. Donovan, John Moult, Vincent A. Fischetti, Frank Heinrich, Mathias Loesche, Daniel C. Nelson
PlyC, a bacteriophage-encoded A-B endolysin, lyses Streptococcus pyogenes (Spy) on contact and protects mice from upper respiratory Spy colonization. Here, we demonstrate that PlyC is a novel, potent agent for targeting and controlling intracellular Spy

An Energy-Efficient Target Tracking Strategy for Mobile Sensor Networks

March 15, 2016
Author(s)
Kamran Sayrafian, Hamid Mahboubi, Walid Masoudimansour, Amir G. Aghdam
In this paper, an energy-efficient strategy is proposed for tracking a moving target in an environment with obstacles, using a network of mobile sensors. Typically, the most dominant sources of energy consumption in a mobile sensor network are sensing

Chapter 7: Quantitative Assessment of Stress Relaxation in Tin Films by the Formation of Whiskers, Hillocks, and Other Surface Defects

March 15, 2016
Author(s)
Nicholas Clore, Dennis D. Fritz, Wei-Hsun Chen, Maureen E. Williams, John E. Blendell, Carol A. Handwerker
This chapter focuses on a study to develop & validate a surface defect counting procedure to be applied in research on the specific mechanisms responsible for stress relaxation & tin whisker formation in tin films. The current JEDEC standards [1,2] for the

End-to-end Demonstration of the Quality Information Framework (QIF) Standard at the International Manufacturing Technology Show (IMTS) 2014

March 15, 2016
Author(s)
Hui-Min Huang, John L. Michaloski, Daniel Campbell, Robert Stone, Thomas Kramer, Curtis Brown, Robert Brown, Gavrai Tatarliev, William Sobel, Lyle Fischer
The "Silos of Quality" in manufacturing can be described as the proliferation of customized quality languages for different stages of production. This quality "tower of babel" results in excessive translations causing loss of information, reduction of
