Dedications

This book is dedicated to my family, to my wife, Sandra, for her never-ending support and belief in me ”not just throughout the last two years of writing but also for the last 12 years of classes, late nights in the lab, on-call, and traveling across the country. And to my two girls , Amanda and Paige, for their understanding and patience while "dad" was locked in the lab. You three are my light, and you make everything in life worthwhile.
