  4. 2. Vertex Operators, String Vertices and Conformal Field Theory Deformations

    Author : Per Sundell; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conformal field theory; vertex operator; Riemann surface; supersymmetry; Reggeon; string theory; sewing;

    Abstract : We compute multi-string interaction vertices by sewing of basic string interaction vertex operators, so called dual Reggeon vertex operators. These operators describe the interaction between two complete external string sectors. They are particularly useful when the interactions involve twisted sectors. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; density functional theory; hydrogen; quantum tunneling; electronic structure; perovskite oxide; metal; first-principles; DFT.; ab-initio;

    Abstract : Atomic hydrogen dissolved in a solid or adsorbed on a solid surfacedisplays many remarkable features, and is a subject ofgreat technological interest.An increased understanding of hydrogen/solid systems can supportthe development of areas as diverse asproton exchange membranes for fuel cells,heterogeneous catalysis, and growth of semiconductor devices.

  7. 5. Using peptide-phage display to capture conditional motif-based interactions

    Author : Gustav Sundell; Ylva Ivarsson; Per Jemth; Attila Reményi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein-protein interaction; PDZ domain; phosphorylation; peptide-phage display; ProP-PD; phospho-peptide; phosphomimetic substitution; Scribble; NMR; DLG1; PTM; affiinity; Biokemi; Biochemistry;

    Abstract : This thesis explores the world of conditional protein-protein interactions using combinatorial peptide-phage display and proteomic peptide-phage display (ProP-PD). Large parts of proteins in the human proteome do not fold in to well-defined structures instead they are intrinsically disordered. READ MORE
