Ac­knowl­edg­ments

Thanks are due to many peo­ple. I par­tic­u­larly want to thank my ma­jor ad­vi­sor, Prof. Jane Doe. With­out her con­stant guid­ance and sup­port, this the­sis would not have ob­tained the high qual­ity that it has. I also thank Profs. Don, Do, Duck, and I for serv­ing on my com­mit­tee. They are sure to rec­og­nize that the level of re­search in this pa­per is fully wor­thy of a Ph.D. Many thanks. This work was sup­ported by the U.S. Cen­tral In­tel­li­gence Agency un­der a se­cret grant.
