  1. 16. Geometry and foundations of quantum mechanics

    Författare :Kate Blanchfield; Ingemar Bengtsson; Anthony Sudberry; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : This thesis explores three notions in the foundations of quantum mechanics: mutually unbiased bases (MUBs), symmetric informationally-complete positive operator valued measures (SICs) and contextuality. MUBs and SICs are sets of vectors corresponding to special measurements in quantum mechanics, but there is no proof of their existence in all dimensions. LÄS MER

  3. 17. Studies on tumor virus epidemiology

    Författare :Davit Bzhalava; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The causal relationship between several virus infections and human cancers are well established. However, it is also possible that additional cancers may be caused by known or yet unknown viruses. LÄS MER

  4. 18. Methods and tools in computer-supported taskforce training

    Författare :Johan Jenvald; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Efficient trammg methods are important for establishing, maintammg and developing taskforces that are organised to manage complex and dangerous situations in order to serve and protect our society. Furthermore, the technical sophistication of various systems in these organisations, for example command, control and communication systems is growing, while the resources available for training are being reduced due to budget cuts and environmental restrictions.

  5. 19. Genetics of complications in patients with type 2 diabetes

    Författare :Sami Alkayyali; diabetes och endokrinologi Genomik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; genetics; genome-wide association studies; type 2 diabetes; diabetes complications.;

    Sammanfattning : Type 2 diabetes (T2D) is a polygenic disease caused by an interaction between genetic and environmental factors such as low physical activity, smoking, and obesity. The disease is associated with devastating chronic microvascular (nephropathy, retinopathy, and neuropathy) and macrovascular (coronary heart disease and stroke) complications. LÄS MER

  7. 20. Avian Genome Evolution - Gene Expression, Gene Divergence and Sexual Dimorphism

    Författare :Sara Naurin; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sex chromosome; avian genome evolution; gene expression; sexual dimorphism; Z chromosome;

    Sammanfattning : This study has focused on: (i) differences in how males and females use the genes in the genome, (ii) how sex chromosomes evolve and (iii) how the evolutionary rate of genes are affected by the chromosome on which they are located on and the gene expression level they experience. A large-scale microarray was developed for the zebra finch, Taeniopygia guttata and techniques were developed so that this microarray could also be used for wild passerine birds. LÄS MER
