In code-division multiple-access systems transmitting data over time-varying multipath channels, both intersymbol interference (ISI) and multiple-access interference (MAI) arise. In this paper, we address interference suppression, multipath diversity and processing gain protection for multiuser detection with less noise enhancement by using a parallel cancelling scheme. The proposed detector co...

Heel pain is one of the most common disorders that foot and ankle surgeons treat. Investigators have stated that of all adult foot complaints, 15% result from heel pain (1). It is important then that the physician know how to properly diagnose and treat this common problem. Although there are many etiologies of plantar heel pain, plantar fasciitis or plantar heel spur syndrome is the most commo...

How should we evaluate public policies or projects that are intended to reduce the likelihood or potential impact of a catastrophic event? Examples might include a greenhouse gas abatement policy to avert a climate change catastrophe, or the construction of levees to avert major flooding. Projects that reduce the likelihood or potential impact of catastrophic events are essentially out-of-the-m...

Intersecting Dp-branes often give rise to chiral fermions living on their intersections. We study the construction of four-dimensional chiral gauge theories by considering configurations of type II D(3 + n)-branes wrapped on non-trivial n-cycles on T × (R/ZN), for n = 1, 2, 3. The gauge theories on the four non-compact dimensions of the brane world-volume are generically chiral and non-supersym...
