  1. 1. Hormonal regulation of liver and tumor growth

    Detta är en avhandling från Göteborg

    Författare :Ville Wallenius; Göteborgs universitet.; Gothenburg University.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liver; cytokine; interleukin-6; tumor necrosis factor; primary liver growth promoter; cyproterone acetate; nafenopin; hepatocyte growth factor; HGF receptor; tumor; sarcoma; N-terminal; truncated;

    Sammanfattning : The aims of this thesis were to investigate the regulatory functions of interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a) on liver growth, and the importance of hepatocyte growth factor (HGF) and the HGF receptor (Met) for growth of mesenchyme-derived tumors. The studies on different types of liver growth, measured as weight, DNA and protein content, and DNA synthesis, were performed on mice lacking the IL-6 or the TNF receptor-1 gene back-crossed to the C57bl/6 strain.

  3. 3. Truncated Signed Distance Fields Applied To Robotics

    Detta är en avhandling från Örebro : Örebro University

    Författare :Daniel Ricão Canelhas; Achim Lilienthal; Todor Stoyanov; Giorgio Grisetti; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D mapping; pose estimation; feature detection; shape description; compression; unsupervised learning; Datavetenskap; Computer Science;

    Sammanfattning : This thesis is concerned with topics related to dense mapping of large scale three-dimensional spaces. In particular, the motivating scenario of this work is one in which a mobile robot with limited computational resources explores an unknown environment using a depth-camera. LÄS MER

  4. 4. Estimators of semiparametric truncated and censored regression models

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Maria Karlsson; Thomas Laitila; Göran Broström; Kenneth Carling; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; LTRC; consistency; asymtotic normality; bootstrap; interpurchase intervals; Statistik; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; Statistics; statistik;

    Sammanfattning : This thesis contributes in several ways to the existing knowledge on estimation of truncated, censored, and left truncated right censored (LTRC) regression models. Three new semiparametric estimators are proposed, allowing for asymmetric error distributions. LÄS MER

  5. 5. Statistical Properties of Preliminary Test Estimators

    Detta är en avhandling från Uppsala : Institutionen för informationsvetenskap

    Författare :Nicklas Korsell; Rolf Larsson; Johan Lyhagen; Tore Schweder; [2006]
    Nyckelord :Statistics; Linear regression; Preliminary test; Model selection; Test for homoscedasticity; Variance components; Truncated estimators; Inertia of matrices; Statistik;

    Sammanfattning : This thesis investigates the statistical properties of preliminary test estimators of linear models with normally distributed errors. Specifically, we derive exact expressions for the mean, variance and quadratic risk (i.e. the Mean Square Error) of estimators whose form are determined by the outcome of a statistical test. LÄS MER
