  4. 2. Electronic Structure Calculations of Point Defects in Semiconductors

    Author : Andreas Höglund; Susanne Mirbt; Alison Mainwood; Uppsala universitet; []
    Keywords : Physics; electronic structure calculations; point defects; semiconductor; formation energy; equilibrium solubility limit; thermodynamic equilibrium concentration; transfer levels; negative-U; 110 surface; diffusion; activation energy; solar cells; Fysik;

    Abstract : In this thesis point defects in semiconductors are studied by electronic structure calculations. Results are presented for the stability and equilibrium concentrations of native defects in GaP, InP, InAs, and InSb, for the entire range of doping conditions and stoichiometry. READ MORE

  5. 3. Regulation of DNA damage responses by the Myc oncogene : implications for future anti-cancer therapies

    Author : Andreas Höglund; Jonas Nilsson; Thomas Helleday; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Myc; DNA damage; Decitabine; Chk1; Chk2; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Myc is a transcription factor frequently found deregulated in human cancer. Cells with deregulated expression of Myc carry a selective advantage against its neighbours due to the fact that Myc-mediated transcription governs crucial cellular events such as proliferation and growth.

  6. 4. Aposematism, Crypsis and Population Differentiation in the Strawberry Poison Frog

    Author : Andreas Rudh; Anna Qvarnström; Jacob Höglund; Michael Speed; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; co-evolution; population divergence; natural selection; sexual selection; warning colouration; Oophaga pumilio; Dendrobates pumilio; aggression; explorative behaviour; colour patterns; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Evolutionary transitions between the two major predator avoidance strategies aposematism and crypsis are expected to be associated with changes in many important traits of animals. However, empirical studies on populations experiencing ongoing or recent transitions between these strategies are rare. READ MORE

  7. 5. Markov Chains, Renewal, Branching and Coalescent Processes : Four Topics in Probability Theory

    Author : Andreas Nordvall Lagerås; Thomas Höglund; Ingemar Kaj; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : This thesis consists of four papers.In paper 1, we prove central limit theorems for Markov chains under (local) contraction conditions. As a corollary we obtain a central limit theorem for Markov chains associated with iterated function systems with contractive maps and place-dependent Dini-continuous probabilities. READ MORE
