  1. 16. Hydrophobicity Patterns in Protein Folding

    Författare :Frank Potthast; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; global optimization; multisequence; Fourier analysis; hydrophobicity; protein folding; simulated tempering; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; gravitation; relativitet; termodynamik; statistisk fysik; alpha-helix; protein design.; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; relativity; Fysicumarkivet A:1998:Potthast;

    Sammanfattning : The protein folding problem is addressed focussing on the hydro- phobicity patterns in the amino acid sequences and structures. Both real and model proteins are investigated. The hydrophobicity pattern of real proteins is probed in two ways. First, it is asked which binary pattern is most conserved within groups of related proteins. LÄS MER

  3. 17. Bell tests and the no-signalling assumption

    Författare :Massimiliano Smania; Mohamed Bourennane; Ingemar Bengtsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum; quantum optics; Bell tests; CHSH inequality; entanglement; fysik; Physics;

    Sammanfattning : Bell's theorem was originally meant for testing fundamental properties of Nature, namely local realism. However, through the years it has become a powerful device for certifying encryption security, randomness, and entanglement among other properties. LÄS MER

  4. 18. Neighborhoods without community : collective efficacy and crime in Malmö, Sweden

    Författare :Manne Gerell; Malmö högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; crime; collective efficacy; geography;

    Sammanfattning : Brottslighet i utsatta bostadsområden har de senaste åren fått stort utrymme i samhällsdebatten. Polisen har börjat sammanställa nationella listor över de bostadsområden i Sverige som anses präglas av kriminella nätverk, samtidigt har media rapporterat att vissa brott, främst skjutningar och bilbränder, är betydligt vanligare i dessa områden än i andra delar av samhället.

    Sammanfattning : Fluoride (F-) concentration in drinking water is one of the water quality parameters in countries with high concentrations in groundwater sources. Natural minerals have shown considerable effectiveness in F- removal. LÄS MER

  7. 20. Optimal adaptive designs and adaptive randomization techniques for clinical trials

    Författare :Yevgen Ryeznik; Warwick Tucker; Andrew Hooker; Franz König; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optimal designs; optimal adaptive designs; randomization in clinical trials; restricted randomization; adaptive randomization; unequal cost; allocation ratio preserving randomization procedures; heterogeneous costs; multi-arm clinical trials; randomization-based inference; unequal allocation; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Sammanfattning : In this Ph.D. thesis, we investigate how to optimize the design of clinical trials by constructing optimal adaptive designs, and how to implement the design by adaptive randomization. LÄS MER
