Basic principles of magnetic stimulation of biological tissues are reviewed. Noninvasive magnetic stimulation of the brain delivered over sensorimotor areas evokes movements and less commonly paresthesias in contralateral limbs. We have evaluated the maps of motor outputs in patients with (1) congenital mirror movements, which resulted in marked derangement(More)

Cyber security is an area where much curriculum development is taking place, and it is important that such efforts be shared. In this work we describe three lab exercises developed at the United States Naval Academy for use in our fundamentals of cyber-security course, a course required of all freshmen. The hands-on lab activities reinforce ideas presented(More)
In spring 2011, the United States Naval Academy decided that, beginning in fall 2011, all first-year students would be required to take an introductory core course in the technical foundations of cyber security. This decision triggered our attempt to set an "academic world-record" for the development and implementation of a unique core course in six months(More)
The health care industry is in the unique position to model health-fulness in food systems. However, there is little available information on the processes that hospitals have used to change food environments.
