1998–2011 Dreams of teaching Kerisha Bowen was born in Trinidad and moved to Toronto before her family finally settled Pennsylvania. A good student, wanted be a professor. She majored chemistry at Lincoln University, then earned an MS PhD Temple University as part program help students from underrepresented groups enter academic careers. Her first job, assistant professor Penn State Brandywine,...

The design of various high-speed interface architectures for off-chip connections to and from analog, iterative VLSI decoders is discussed. It is shown that for applications with high transmission rates and low to medium accuracy, MOSFET-only R-2R ladders in combination with switched-current memory cells are ideally suited, due to their current mode nature as well as their power and area effici...

For Schwarzschild space-time, distributional expressions of energy-momentum densities and of scalar concomitants of the curvature tensors are examined for a class of coordinate systems which includes those of the Schwarzschild and of Kerr-Schild types as special cases. The energy-momentum density e T (x) of the grav-itational source and the gravitational energy-momentum pseudo-tensor density e ...

In contour integration, increased difficulty in detection and shape discrimination of a chain of parallel elements (a ladder contour) compared to collinear elements (a snake contour) suggests more extensive processing of ladders than of snakes. In addition, conceptual similarities between ladders and textures - which also involve grouping of parallel elements - raises the question whether ladde...

Yale University and University of California, Berkeley Let Sn n ≥ 0 be a random walk having normally distributed increments with mean θ and variance 1, and let τ be the time at which the random walk first takes a positive value, so that Sτ is the first ladder height. Then the expected value EθSτ, originally defined for positive θ, may be extended to be an analytic function of the complex variab...
