The magnetic tunnel junction (MTJ)-related materials such as CoFeB, CoPt, MgO, and Ru, and W were etched using CH3OH in a pulse-biased inductively coupled plasma system and the effect of bias pulsing (100% 30% duty percentage) on the etch characteristics of the MTJ-related materials was investigated at the substrate temperature of 200 degrees C. The etch selectivity of MTJ-related materials ove...

Background: The most recent regulations regarding resident duty hours became effective in July, 2011 and included restriction of shifts to a maximum of 16 hours for interns in all specialties. There is little objective data regarding the impact of these new duty hour limits on resident education. We hypothesized that the duty hour changes would not have a significant impact on intern educationa...

We exploit plausibly exogenous variation in overseas deployment assignment to estimate the effect of combat exposure on psychological well-being. Controlling for pre-deployment mental health, we find that active-duty soldiers deployed to combat zones are more likely to suffer from post-traumatic stress disorder (PTSD) than their counterparts deployed outside the United States in non-combat zone...

The loading of free wheel diodes (FWD) and IGBTs in the power modules of a Voltage Source Converter (VSC) are investigated. In converter duty, the FWD is utilized more then the IGBT. Presently, most FWD’s in power modules are optimized for inverter duty. This practice tends to undersize the FWD from a converter viewpoint. This design philosophy is examined in the paper. For this purpose, the or...

OBJECTIVES To investigate the association between stress, shift work, and eating behavior among non-Saudi female nurses working in Central Saudi Arabia. METHODS A sample of 395 non-Saudi female nurses from 2 major hospitals in Riyadh, Kingdom of Saudi Arabia participated in this cross-sectional study. The nurses completed a questionnaire from November 2013 to January 2014 that included items ...

This study examined gender differences in posttraumatic stress disorder (PTSD) symptoms and symptom factors in the total U.S. active duty force. Data were drawn from the 2008 Department of Defense Survey of Health Related Behaviors among Active Duty Military Personnel including 17,939 men and 6751 women from all services. The results indicated that women expressed more distress than men across ...
