Structural Collapse and Superconductivity in Rare-Earth-Doped CaFe 2 As 2

January 13, 2012
Author(s)
S. R. Saha, N. P. Butch, T. Drye, J. Magill, S. Ziemak, K. Kirshenbaum, P. Y. Zavalij, Jeffrey W. Lynn, J. Paglione
The interplay between structural, magnetic and superconducting properties in the newly discovered iron-based superconducting compounds has been a central theme in attempts to elucidate the nature of Cooper pairing in this new family of high-temperature

ITRS Chapter: RF and A/MS Technologies

January 12, 2012
Author(s)
Herbert S. Bennett, John J. Pekarik
Radio frequency and analog/mixed-signal (RF and A/MS) technologies are essential and critical technologies for the rapidly diversifying semiconductor market that comprises many more applications than the wireless and wire-line communications market that

MEMS

January 12, 2012
Author(s)
Michael Gaitan
Micro-Electro-Mechanical Systems (MEMS) are devices that are fabricated using techniques similar to those used for integrated circuits (ICs) to create micrometer-sized mechanical structures (suspended bridges, cantilevers, membranes, fluid channels, etc.)

CFD Modeling of Fire

January 11, 2012
Author(s)
Kevin B. McGrattan, Randall J. McDermott, Glenn P. Forney, Jason E. Floyd, Simo A. Hostikka, Howard R. Baum
An overview of a methodology for simulating fires and other thermally-driven, low-speed flows is presented. The model employs a number of simplifications of the governing equations that allow for relatively fast simulations of practical fire scenarios. The

Atom-number amplification in a magneto-optical trap via stimulated light forces

January 10, 2012
Author(s)
Elizabeth A. Donley, Tara C. Liebisch, Eric M. Blanshan, John E. Kitching
We have decelerated an atomic beam of 87 Rb using a stimulated-emission slowing technique that makes use of a bichromatic standing light wave of high intensity and increased the load rate into a small magneto-optical trap by up to a factor of 20. We

Conclusive quantum steering with superconducting transition-edge sensors

January 10, 2012
Author(s)
Devin H. Smith, Marcelo de Almeida, Gillett Geoff, Branciard Cyril, Allesandro Fedrizzi, Weinhold J. Till, Adriana Lita, Brice R. Calkins, Thomas Gerrits, Wiseman H, Sae Woo Nam, Andrew G. White
Quantum steering allows two parties to verify shared entanglement even if one measurement device is untrusted. A conclusive demonstration of steering through the violation of a steering inequality is of considerable fundamental interest and opens up

Pilot Estuarine Mesocosm Study on the Environmental Fate of Silver Nanomaterials Leached from Consumer Products

January 10, 2012
Author(s)
Danielle Cleveland, Stephen E. Long, Paul L. Pennington, Emily Cooper, Michael H. Fulton, Geoffrey I. Scott, Elijah J. Petersen, Timothy M. Brewer, Jeffrey M. Davis, Laura J. Wood
Although nanosilver consumer products (CPs) now enjoy widespread availability, little work has been done to determine the environmental fate and leaching of silver nanoparticles (AgNPs) from these products. This type of work is crucial, since the lifecycle

Static Analyzers: Seat Belts for Your Code

January 10, 2012
Author(s)
Paul Black
Just as seat belt use is wide spread, we argue that the use static analysis should be part of ethical software development. We explain some of the procedures of the four Static Analysis Tool Expositions (SATE), and some of the lessons we learned
