Methods and Tools for Performance Assurance of Smart Manufacturing Systems

December 22, 2015
Author(s)
Deogratias Kibira, Katherine C. Morris, Senthilkumaran Kumaraguru
The emerging concept of smart manufacturing systems is defined in part by the introduction of new technologies that are promoting rapid and widespread information flow within the manufacturing system and surrounding its control. These systems can deliver

Scattering Studies on Poly(3,4-ethylenedioxythiophene) Polystyrenesulfonate in the Presence of Ionic Liquids

December 22, 2015
Author(s)
Ryan J. Murphy, Kathleen Weigandt, David Uhrig, Ahmed Alsayed, Chantal Badre, Larry Hough, Murugappan Muthukumar
The demand for lower-cost and flexible electronics has driven industry to develop alternative transport electrode (TE) materials to replace Indium Tin Oxide (ITO). ITO is the benchmark TE on the market, but its high cost and low flexibility limits it for

Intrinsic Spin Torque Without Spin-Orbit Coupling

December 21, 2015
Author(s)
Kyoung-Whan Kim, Kyung-Jin Lee, Hyun-Woo Lee, Mark D. Stiles
For non-uniform magnetic textures, we derive an intrinsic contribution to the non-adiabatic spin torque that may be the dominant contribution. It differs from previously considered contributions in several ways. It does not depend on the change in

Managing Risk in a Cloud Ecosystem

December 18, 2015
Author(s)
Michaela Iorga, Anil Karmel
The article focuses on the tier 3 security risks related to the operation and use of cloud-based information systems. To prevent and mitigate any threats, adverse actions, service disruptions, attacks, or compromises, organizations need to quantify their

New perspective on glycoside hydrolase binding to lignin from pretreated corn stover

December 18, 2015
Author(s)
John M. Yarbrough, Ashutosh Mittal, Elisabeth Mansfield, Larry Taylor, Sarah Hobdey, Deanne W. Sammond, Yannick J. Bomble, Michael F. Crowley, Stephen R. Decker, Michael E. Himmel, Todd B. Vinzant
Non-specific binding of cellulases to lignin has been implicated as a major factor in the loss of cellulase activity during biomass conversion to sugars. It is believed that this binding may strongly impact process economics through loss of enzyme

Polarity-Controlled GaN/AlN Nucleation Layers for Selective-Area Growth of GaN Nanowire Arrays on Si(111) Substrates by Molecular Beam Epitaxy

December 18, 2015
Author(s)
Matthew D. Brubaker, Shannon M. Duff, Todd E. Harvey, Paul T. Blanchard, Alexana Roshko, Aric W. Sanders, Norman A. Sanford, Kristine A. Bertness
We have demonstrated dramatic improvement in the quality of selective-area GaN nanowire growth by controlling the polarity of the underlying nucleation layers. In particular, we find that N- polarity is beneficial for the growth of large ordered nanowire

Third-Party Software's Trust Quagmire

December 18, 2015
Author(s)
Jeffrey M. Voas, George Hurlburt
Integrating software developed by third-party organizations into a larger system raises concerns about the software's quality, origin, functionality, security, and interoperability. Addressing these concerns requires rethinking the roles of software's

Direct observation of Feshbach enhanced s-wave scattering of fermions

December 17, 2015
Author(s)
Dina Genkina, Lauren M. Aycock, Hsin I Lu, Ian B. Spielman, Benjamin K. Stuhl
We directly measured the s-wave scattering cross-section of ultracold 40K atoms across the 20.2 mT Feshbach resonance by colliding pairs of degenerate Fermi gases (DFGs) and imaging the scattered atoms. Owing to DFG’s low density, few atoms scattered, even
