  1. 11. Structures in complex systems : Playing dice with networks and books

    Författare :Sebastian Bernhardsson; Petter Minnhagen; Stefan Bornholdt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex systems; networks; statistical physics; biological networks; quantitative linguistics; word frequencies.; Physics; Fysik;

    Sammanfattning : Complex systems are neither perfectly regular nor completely random. They consist of a multitude of players who, in many cases, playtogether in a way that makes their combined strength greater than the sum of their individual achievements. LÄS MER

  2. 12. The role of implementation science in healthcare improvement efforts : investigating three complex interventions

    Författare :Anna Westerlund; Monica Nyström; Anneli Ivarsson; Rickard Garvare; Eva Eurenius; Johan Thor; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; healthcare improvement; knowledge-practice gap; implementation science; complex interventions; implementation strategy; change facilitation; case studies; folkhälsa; Public health; hälso- och sjukvårdsforskning; health services research;

    Sammanfattning : For decades, scholars have found significant gaps between the knowledge available and the knowledge applied in healthcare. Many potential benefits of adequate knowledge based interventions are therefore never achieved. A considerable body of knowledge has evolved on how to promote a better uptake of evidence-based knowledge into routine use. LÄS MER

  3. 13. Organization of information pathways in complex networks

    Författare :Atieh Mirshahvalad; Martin Rosvall; Santo Fortunato; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex systems; Complex Networks; Information; Communication; Community Detection; Significance Analysis; Resampling; Information Spreading.; computer and systems sciences; data- och systemvetenskap;

    Sammanfattning : A shuman beings, we are continuously struggling to comprehend the mechanism of dierent natural systems. Many times, we face a complex system where the emergent properties of the system at a global level can not be explained by a simple aggregation of the system's components at the micro-level. LÄS MER

  4. 14. On complex convexity

    Författare :David Jacquet; Mikael Passare; Peter Pflug; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ℂ-convex; Linearly convex; Charathéodory metric; Kobayshi metric; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : This thesis is about complex convexity. We compare it with other notions of convexity such as ordinary convexity, linear convexity, hyperconvexity and pseudoconvexity. We also do detailed study about ℂ-convex Hartogs domains, which leads to a definition of ℂ-convex functions of class C1. LÄS MER

  5. 15. Complex Trait Genetics : Beyond Additivity

    Författare :Simon Forsberg; Örjan Carlborg; Julien Ayroles; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genetic interactions; epistasis; additivity; GWAS; vGWAS; Genetic mapping; yeast; Arabidopsis Thaliana; dog; Genetik; Genetics;

    Sammanfattning : The link between the genotype and the phenotype of an organism is immensely complex. Despite this it can, to a great extent, be captured using models that assume that gene variants combine their effects in an additive manner. This thesis explores aspects of genetics that cannot be fully captured using such additive models. LÄS MER
