  • Comparing 17 graph parameters 

    Sasák, Róbert (The University of Bergen, 2010-08-02)
    Many parametrized problems were decided to be FPT or W-hard. However, there is still thousands of problems and parameters for which we do not know yet whether are FPT or W-hard. In this thesis, we provide a tool for extending ...

  • Computation of Treespan. A Generalization of Bandwidth to Treelike Structures 

    Dregi, Markus Sortland (The University of Bergen, 2012-06-14)
    Motivated by a search game, Fomin, Heggernes and Telle [Algorithmica, 2005] defined the graph parameter treespan, a generalization of the well studied parameter bandwidth. Treespan is the maximum number of appearances ...

  • Computational analysis of the evolutionary dynamics of proteins on a genomic scale 

    Hughes, Timothy (The University of Bergen, 2007-01-16)
    Biology is primarily concerned with the study of all phenotypic aspects of living organisms and evolutionary biology is more specifically interested in elucidating how different phenotypes evolved. Proteins (and RNA ...

  • Conserved BK Channel-Protein Interactions Reveal Signals Relevant to Cell Death and Survival 

    Sokolowski, Bernd; Orchard, Sandra; Harvey, Margaret; Sridhar, Settu; Sakai, Yoshihisa (Public Library of Science, 2011-12-09)
    The large-conductance Ca2+-activated K+ (BK) channel and its b-subunit underlie tuning in non-mammalian sensory or hair cells, whereas in mammals its function is less clear. To gain insights into species differences and ...

  • Continuous Levels-of-Detail and Visual Abstraction for Seamless Molecular Visualization 

    Parulek, Julius; Jönsson, Daniel; Ropinski, Timo; Bruckner, Stefan; Ynnerman, Anders; Viola, Ivan (Wiley, 2014-05-06)
    Molecular visualization is often challenged with rendering of large molecular structures in real time. We introduce a novel approach that enables us to show even large protein complexes. Our method is based on the ...
