  2. 1. Data Analysis and Next Generation Sequencing : Applications in Microbiology

    Author : Nicolas Innocenti; Erik Aurell; Mogens Jensen; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; RNA-seq; tagRNA-seq; primary and processed RNA; Enterococcus faecalis; Complex transcription; Metagenomics; 5 tagRACE; minimal absent words; compressed sensing; metagenomics; bacterial community reconstruction; Biological Physics; Biologisk fysik;

    Abstract : Next Generation Sequencing (NGS) is a new technology that has revolutionized the way we study living organisms. Where previously only a few genes could be studied at a time through targeted direct probing, NGS offers the possibility to perform measurements for a whole genome at once. READ MORE

  4. 2. Computational modeling of biological barriers

    Author : Christian Wennberg; Erik Lindahl; Thomas Cheatham; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; cholesterol; lipid bilayer; permeability; long-range interactions; Lennard-Jones; dispersion; particle-mesh Ewald; stratum corneum; skin formation; Biologisk fysik; Biological Physics;

    Abstract : One of the most important aspects for all life on this planet is the act to keep their biological processes in a state where they do not reach equilibrium. One part in the upholding of this imbalanced state is the barrier between the cells and their surroundings, created by the cell membrane. READ MORE

  5. 3. Statistical Physics of Protein Folding and Aggregation

    Author : Giorgio Favrin; Beräkningsbiologi och biologisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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;

    Abstract : 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. READ MORE

  6. 4. Variational Methods in Combinatorial Optimization and Phylogeny Reconstruction

    Author : Henrik Jönsson; Beräkningsbiologi och biologisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; annealing; variational; mean-field; phylogeny; constraint satisfaction; combinatorial optimization; maximum likelihood; Physics; Fysik; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2001:Jönsson; Matematisk och allmän teoretisk fysik; thermodynamics;

    Abstract : Algorithms based on the variational approach, as used in statistical physics, are developed. For constraint satisfaction problems a novel cost function, based on information-theoretic arguments, is introduced, and an algorithm similar to the mean-field annealing algorithm is proposed.

    Author : Joachim Piguet; Horst Vogel; Ruud Hovius; Jerker Widengren; Antoine Triller; Switzerland Ecole Polytechnique Fédérale de Lausanne (EPFL); []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biologisk fysik; Biological Physics;

    Abstract : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. READ MORE
