First principles force field for metallic tantalum
We develop a many-body force field (FF) for tantalum based on extensive ab initio quantum mechanical (QM) calculations and illustrate its application with molecular dynamics (MD). As input data to the FF we use ab initio methods (LAPW-GGA) to calculate: (i) the zero temperature equation of state (EOS) of Ta for bcc, fcc, and hcp crystal structures for pressures up to ∼500 GPa, and (ii) elastic ...
متن کاملMetro Stroke Task Force: first-year experience.
According to recent statistics, stroke is the third leading cause of death and a leading cause of serious, long-term disability. Of the estimated 40 000 ischemic strokes per month in the United States, only approximately 2% are being treated with tPA. A primary reason for the underutilization of tPA is the lack of public awareness of stroke warning signs and the urgent nature of stroke. In an a...

15 صفحه اولAir Force Culture and Cohesion: Building an Air and Space Force for the Twenty-First Century
THE US AIR FORCE has a co he sion problem. Dr. Donald B. Rice, former secre tary of the Air Force, complained that offi cers identi fied with their weapon systems, not with the Air Force or any concept of service mission or doctrine. Carl Builder agrees. To Builder, the Air Force has no strong, unify ing mission or vi sion, so loyalty has devolved to functions, tech nolo gies, and occu pa tio...
متن کاملForce from Motion: Decoding Control Force of Activity in a First Person Video
A first person video delivers what the camera wearer experiences while physically interacting with surroundings. In this paper, we focus on a problem of Force from Motion—decoding control force and torque that drive the activity—from a first person video. We use two dominant physical factors encoded in the video to understand the wearer’s activity: physical coordinate system and active force co...
