A next-to-leading-order calculation of proton-proton(proton-antiproton) to two jets, at least one of which contains a charm quark
… this thesis, I present a next-to-leading-order (NLO) calculation for the production of two jets, at least one of which contains a charm quark, which is an important background to single-top production. I discuss the leading order results and their scale dependence before outlining the …

Interface Effects and Deposition Process of Ionically Self-Assembled Monolayer Films: In Situ and Ex Situ Second Hamonic Generation Measurements
… During the deposition of the nonlinear optical (NLO) active layer, the chromophores are attracted to the oppositely-charged surface, which results in net orientation of the chromophores. Some of the net orientation is lost during the deposition of the next NLO-inactive layer as this layer orients …
