Acknowledgments
We should first thank the chapter authors and acknowledge their contributions to the book, as well as their support and patience. We would also like to thank the reviewers for their useful comments and suggestions that helped in improving the earlier outline of the book and presentation of the material. We should extend our deepest thanks to Simone Taylor, Melissa Yanuzzi, and Diana Gialo from Wiley (USA) for their collaboration, guidance, and most importantly, patience in finalizing this volume. Last but not the least, we are very grateful to the lovely team from Wiley's production department for their extensive efforts during the many phases of this project and the timely fashion in which the book was produced.
