I could go on with thanking John Harvard’s Brewehouse in Cambridge for making the best chicken wings in the world, the Boston Red Sox for winning the world series, the “Kleiner Ochsenbrater” at the Viktualienmark in Munich for the best “Ochsen Zwibelrostbraten”; but actually, there is just one person left. Since this person is so special, I keep on feeling that no words are suited expressing my feel- ings about her. Beyond any experience I gained during this dissertation, there is one thing that stands high above. Thanks to the great ability of our joint doctoral advisor in selecting his students,.
