  1. 1. Light from Dark Matter : Hidden Dimensions, Supersymmetry, and Inert Higgs

    Författare :Michael Gustafsson; Lars Bergström; Steen Hannestad; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Recent observational achievements within cosmology and astrophysics have lead to a concordance model in which the energy content in our Universe is dominated by presumably fundamentally new and exotic ingredients – dark energy and dark matter. To reveal the nature of these ingredients is one of the greatest challenges in physics. LÄS MER

  3. 2. Consequences of Shb Deficiency on Hematopoietic Cell Function

    Författare :Karin Gustafsson; Michael Welsh; Martin Bergö; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoiesis; hematopoietic stem cells; myeloid neoplasia; T cells; atopic dermatitis; cell signaling; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : The adaptor protein Shb has been implicated in the signaling of several tyrosine kinase receptors and previous studies have suggested a role for Shb in the signal transduction of T cells. Shb associates with the T cell receptor (TCR) and partakes in the signal propagation of activated T lymphocytes. LÄS MER

  4. 3. Kalman Filters for Nonlinear Systems and Heavy-Tailed Noise

    Författare :Michael Roth; Fredrik Gustafsson; Simo Särkkä; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis is on filtering in state space models. First, we examine approximate Kalman filters for nonlinear systems, where the optimal Bayesian filtering recursions cannot be solved exactly. These algorithms rely on the computation of certain expected values. LÄS MER

  5. 4. Characterization of particulate matter from atmospheric fluidized bed biomass gasifiers

    Författare :Eva Gustafsson; Michael Strand; Marcus Öhman; Linnéuniversitetet; []
    Nyckelord :biomass gasification; fluidized bed; particulate matter; particle morphology; particle elementary composition; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Sammanfattning : Through biomass gasification, biomass can be converted at high temperature to a product gas rich in carbon monoxide, hydrogen, and methane. After cleaning and upgrading, the product gas can be converted to biofuels such as hydrogen; methanol; dimethyl ether; and synthetic diesel, gasoline, and natural gas. LÄS MER

  7. 5. Gene networks from high-throughput data : Reverse engineering and analysis

    Författare :Mika Gustafsson; Michael Hörnquist; Jesper Tegnér; Reinhard Guthke; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Experimental innovations starting in the 1990’s leading to the advent of high-throughput experiments in cellular biology have made it possible to measure thousands of genes simultaneously at a modest cost. This enables the discovery of new unexpected relationships between genes in addition to the possibility of falsify existing. LÄS MER
