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

August 17, 2015
Author(s)
Mingda Li, Cui-Zu Chang, Brian Kirby, Michelle E. Jamer, Wenping Cui, Lijun Wu, Peng Wei, Yimei Zhu, Don Heiman, Ju Li, Jagadeesh S. Moodera
Magnetic exchange driven proximity effect at a magnetic insulator/topological insulator (MI/TI) interface provides a rich playground for novel phenomena as well as a way to realize low energy dissipation quantum devices. Here we report a dramatic

Technical Basis for User Interface Design of Health IT

August 17, 2015
Author(s)
Michael E. Wiklund, Jonathan Kendler, Limor Hochberg, Matthew B. Weinger
This document is intended to help EHR developers plan and implement a user-centered design for their EHR systems. It includes user interface design principles that are customized for EHR environment. Specifically, it provides: (1) Descriptions of the

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

August 15, 2015
Author(s)
Kirt A. Page, Jae W. Shin, Scott Eastman, Brandon W. Rowe, Sangcheol Kim, Ahmet Kusoglu, Kevin G. Yager, Gery R. Stafford
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

August 15, 2015
Author(s)
J. R. Machacek, D. P. Mahapatra, David R. Schultz, Yuri Ralchenko, A. Moradmand, O. E. Ghazaly, A. Chutjian
Relevant to modeling and understanding X-ray emission from cometary and planetary atmospheres, total cross sections for 1.17 and 2.33 keV/u O6+ colliding with H2O, CO, CO2, CH4, N2, NO, N2O, and Ar have been measured for the processes of single, double

Experiments with highly-ionized atoms in unitary Penning traps

August 14, 2015
Author(s)
Shannon Hoogerheide, Aung Naing, Joan M. Dreiling, Samuel M. Brewer, Nicholas D. Guise, Joseph N. Tan
Highly-ionized atoms with special properties have been proposed for interesting applications, including potential candidates for a new generation of optical atomic-clocks at the 1 part in 1019 level of precision, quantum-information processing, and tests

Frequency-tunable Superconducting Resonators via Nonlinear Kinetic Inductance

August 13, 2015
Author(s)
Michael Vissers, Johannes Hubmayr, Jiansong Gao, Martin Sandberg, Saptarshi Chaudhuri, Clint Bockstiegel
We have designed, fabricated and tested a frequency-tunable high-Q superconducting resonator made from niobium titanium nitride film. The frequency tunability is achieved by injecting a DC current through a special current-directing circuit into the
