  2. 1. Superfluid Phase Transitions in Disordered Systems

    Author : Hannes Meier; Mats Wallin Wallin; Peter Olsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents results from large scale Monte Carlo simulations of systems subject to a superfluid phase transition in the presence of disorder. The simulations are performed by state-of-the-art, collective Monte Carlo algorithms treating phase degrees of freedom in effective models with amplitude fluctuations integrated out. READ MORE

  4. 2. Physical Modeling of Protein Folding

    Author : Stefan Wallin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; relativity; quantum mechanics; classical mechanics; three-helix bundle; similarity measure; Mathematical and general theoretical physics; protein dynamics; protein folding; two-state; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Wallin;

    Abstract : Sequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. READ MORE

  5. 3. Evasion of CO₂ from streams : quantifying a carbon component of the aquatic conduit in the boreal landscape

    Author : Marcus Wallin; Robert Striegl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Lateral export of carbon (C) from soils to running waters is a persistent pathway for C with terrestrial origin. This "aquatic conduit" might be especially important in boreal regions where a significant part of the global C stock is stored in the soil. READ MORE

  6. 4. Balance control in people with multiple sclerosis : mechanisms, experiences, design and feasibility of an exercise trial

    Author : Andreas Wallin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Everyday living entails navigating complex environments and perform-ing activities often requiring simultaneous motor and cognitive actions/tasks (dual-tasking). Disease-related impairments in people with multiple sclerosis (MS) often impact sensorimotor and cognitive functions, both of which may contribute to a vicious cycle of decreased mobility, muscular weakness, impaired balance control, walking limitation, falls, and fall-related injuries.

  7. 5. Explaining everyday problem solving

    Author : Annika Wallin; Kognitionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; domain-specificity; ecological rationality; evolutionary psychology; practice theory; situated action; universal problem solver; everyday cognition; Explanations; everyday problem solving; domain-generality; causality; social information; Psychology; Psykologi;

    Abstract : How well can we explain natural occurrences of cognitive behaviours given the theoretical frameworks available to us today? The thesis explores what has to be assumed in cognitive theory in order to provide such an explanation, in contrast to being able to predict behaviour under controlled circumstances. The behaviours considered are all of the type described as involving higher level cognition or being representation hungry. READ MORE
