Acknowledgments
This book has benefited from the assistance of numerous professionals and colleagues. I would like to thank specifically Tim Bell and Ram Menon for their invaluable review of earlier chapters of the book. I also thank the publishing team at John Wiley & Sons for their help, particularly John DeRemigis, Stacey Rivera, Natasha Andrews-Noel and Dexter Gasque in Hoboken, NJ. The assistance of my graduate students, Yue Zhang, Kyle Griffiths, Sudeshna Gunna, Mansi Gadi, and Amir Alimardani is greatly appreciated.
The encouragement and support of my family and colleagues are also acknowledged. I am thankful for the love, patience, and support of my wife, Soheila, my son, Nick, and my daughter, Rose, in making it easier for me to focus on completing the third revision of this book.
