This work benefited greatly from discussions with Profs. Hsi-Sheng Goan (National Taiwan University), Jyh-Pin Chou (National Changhua University of Education), Hao-Chung Cheng (National Taiwan University), and Dr. Piotr Czarnik (Los Alamos National Laboratory). All remaining deficiencies are my own.
