  5. 3. Regulation of cytokine receptors and activity markers in eosinophilic inflammatory processes

    Author : Cecilia Hellman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The eosinophil is an important effector cell in allergic inflammation and asthma and an increased number of eosinophils and eosinophil-derived cytotoxic proteins have been found in blood and airways of allergic patients. The life cycle of the eosinophil starts with differentiation of bone marrow progenitor cells. READ MORE

  6. 4. Multiscale and multilevel methods for porous media flow problems

    Author : Fredrik Hellman; Axel Målqvist; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : We consider two problems encountered in simulation of fluid flow through porous media. In macroscopic models based on Darcy's law, the permeability field appears as data.The first problem is that the permeability field generally is not entirely known. READ MORE

  7. 5. Numerical Methods for Darcy Flow Problems with Rough and Uncertain Data

    Author : Fredrik Hellman; Axel Målqvist; Auli Niemi; Fritjof Fagerlund; Robert Scheichl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerical homogenization; multiscale methods; rough coefficients; high contrast coefficients; mixed finite elements; cdf estimation; multilevel Monte Carlo methods; Darcy flow problems; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : We address two computational challenges for numerical simulations of Darcy flow problems: rough and uncertain data. The rapidly varying and possibly high contrast permeability coefficient for the pressure equation in Darcy flow problems generally leads to irregular solutions, which in turn make standard solution techniques perform poorly.
