1. Student: Joyce Biaco Major: Chemistry Mentor: Timothy Barker Department: Chemistry and Biochemistry Title: Lewis Acid-Catalyzed Minisci Reactions Many pharmaceutical drugs contain at least one nitrogen atom. If that nitrogen atom is part of a ring with carbon atoms it is called a heterocycle. The ability to easily modify a heterocycle is useful to medicinal chemists because they are then abl...

We construct the heterotic dual theory in four dimensions of eleven dimensional supergravity compactified on a particular Joyce manifold, J. In particular J is constructed from resolving fixed point singular-ities of orbifolds of the seven-torus in such a way that one is forced to consider a generalised orbifold compactification on the heterotic side. We conjecture that a heterotic dual exists ...

Recently, Tanaka et al. (in press) have shown that subjects trained at the subordinate level (henceforth, “experts”) exhibit an advantage over subjects trained at the basic level on the same stimuli in performing discrimination tasks within their domain of expertise, showing that “mere exposure” to a category is not enough to induce discrimination behavior consistent with expertise. In addition...
