  1. 21. Narrowing the gap between network models and real complex systems

    Författare :Alcides Viamontes Esquivel; Martin Rosvall; Joachim Mathiesen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; complex systems; network science; community detection; model selection; signficance analysis; ergodicity; fysik; Physics;

    Sammanfattning : Simple network models that focus only on graph topology or, at best, basic interactions are often insufficient to capture all the aspects of a dynamic complex system. In this thesis, I explore those limitations, and some concrete methods of resolving them. LÄS MER

  3. 22. Expression and Mutagenesis studies of Candida antactica lipase B

    Författare :Johanna C. Rotticci-Mulder; KTH; []
    Nyckelord :Protein expression; Candida antarctica lipase B; Pichia pastoris; site-directed mutagenesis; fermentation; selection;

    Sammanfattning : Recombinant Candida antarctica lipase B was successfullyproduced in the methylotropic yeast Pichia pastoris. Thespecific activities of Candida antarctica lipase B produced inPichia pastoris and commercial Candida antarctica lipase B fromNovozymes were the same. In shake-flask cultivations theexpression levels were about 25 mg L-1. LÄS MER

  4. 23. Communication in Games and Decision Making under Risk

    Författare :Erik Wengström; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Communication; Repeated Bertrand Games Cooperation; Renegotiation; Experiments; Risk Aversion; Non-cooperative Game Theory; Selection; Loss Aversion; Timing of Uncertainty Resolution;

    Sammanfattning : This thesis is divided into two distinct parts. The first part studies communication in games and the second part investigates individual decision making under risk. Chapters 2 – 4, co-authored with Ola Andersson, investigate communication and renegotiation in dynamic games. LÄS MER

  5. 24. Models in Neutrino Physics : Numerical and Statistical Studies

    Författare :Johannes Bergström; Tommy Ohlsson; Pilar Hernandez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutrino mass; lepton mixing; Majorana neutrinos; neutrino oscillations; neutrinoless double beta decay; statistical methods; Bayesian inference; model selection; effective field theory; Weinberg operator; seesaw models; inverse seesaw; right-handed neutrinos; renormalization group; threshold effects.; Neutrinomassor; leptonblandning; Majorananeutriner; neutrinooscillationer; neutrinol¨ost dubbelt betas¨onderfall; statistiska metoder; Bayesisk inferens; modellval; effektiv f¨altteori; Weinbergoperator; seesawmodeller; invers seesaw; högerhänta neutriner; renormeringsgrupp; tröskeleffekter.;

    Sammanfattning : The standard model of particle physics can excellently describe the vast majorityof data of particle physics experiments. However, in its simplest form, it cannot account for the fact that the neutrinos are massive particles and lepton flavorsmixed, as required by the observation of neutrino oscillations. LÄS MER

  7. 25. Biological effects of high energy radiation and ultra high dose rates

    Författare :Björn Zackrisson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiobiology; 50 MV x-rays; 50 MeV electrons; in vitro; in vivo; RBE; OER; ultra high dose-rate; radiobiological models; model selection; models of stochastic processes;

    Sammanfattning : Recently a powerful electron accelerator, 50 MeV race-track microtron, has been taken into clinical use. This gives the opportunity to treat patients with higher x-ray and electron energies than before. Furthermore, treatments can be performed were the entire fractional dose can be delivered in parts of a second. LÄS MER
