  1. 1. Modeling of Protein Folding and Genetic Networks

    Författare :Fredrik Sjunnesson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; two-state folding; Protein folding; all-atom model; Mathematical and general theoretical physics; Kauffman model.; local update; Monte Carlo; classical mechanics; quantum mechanics; relativity; statistical physics; gravitation; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Sjunnesson;

    Sammanfattning : Models for potein folding are developed and applied to peptides and small proteins with both α-helix and β-sheet structure. The energy functions, in which effective hydrophobicity forces and hydrogen bonds are taken to be the two central terms, are sequence-based and deliberately kept simple. LÄS MER

  3. 2. First step to a genomic CALPHAD database for cemented carbides : C-Co-Cr alloys

    Författare :Zhou Li; Malin Selleby; Jana Pavlu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CALPHAD; Einstein model; two-state model; compound energy formalism; thermodynamic description; C-Co-Cr; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : CALPHAD (CALculation of PHAse Diagrams) denotes the methodology used to assess thermodynamic data based on experiments as well as on first principles calculations. Essential for this method is the coupling of phase diagram and thermodynamic properties. LÄS MER

  4. 3. Rate Limiting Factors For Protein Folding

    Författare :Maria Berggård Silow; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kinetic competition; transient aggregation; diffusion control; reconfiguration time; collapse; osmolytes; broad barriers; Hammond behaviour; two-state; U1A; CI2; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : Abstract. This thesis describes factors that are rate limiting for the folding of two small proteins, U1A and CI2 which fold without accumulating intermediates. The [GdnHCl] dependencies of the unfolding- and refolding kinetics of U1A display downward curvatures. LÄS MER

  5. 4. Statistical Physics of Protein Folding and Aggregation

    Författare :Giorgio Favrin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Two State; Physics; Fysik; Statistics; operations research; programming; aktuariematematik; programmering; operationsanalys; actuarial mathematics; Statistik; Simulations; Aggregation; Protein Folding; Fysicumarkivet A:2004:Favrin;

    Sammanfattning : The mechanisms of protein folding and aggregation are investigated by computer simulations of all-atom and reduced models with sequence-based potentials. A quasi local Monte Carlo update is developed in order to efficiently sample proteins in the folded phase. LÄS MER

  7. 5. Macroeconometric Studies of Private Consumption, Government Debt and Real Exchange Rates

    Författare :Jesper Hansson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; econometrics; Economics; Real exchange rate; Public debt; Structural VAR model; Cointegration; Habits; Permanent income hypothesis PIH ; economic theory; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

    Sammanfattning : Advances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate.
