  1. 16. Death mechanisms compromising hippocampal neurogenesis after status epilepticus

    Författare :Christine Ekdahl Clementson; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; minocycline; lipopolysaccharide; microglia activation; status epilepticus; epilepsy; cysteinyl aspartate-specific proteases; apoptosis; neurogenesis; progenitor cell progeny;

    Sammanfattning : Status epilepticus (SE) leads to neurodegeneration as well as neurogenesis in the adult rat hippocampus. This thesis demonstrates that even if the neurogenic response initially is very pronounced, with a several-fold increase in cell proliferation, the survival of the newly formed neurons is compromised by a death mechanism involving mitochondria-related caspases.

  3. 18. Approximations of Bayes Classifiers for Statistical Learning of Clusters

    Författare :Magnus Ekdahl; Timo Koski; Jukka Corander; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pattern Recognition; Stochastic Complexity; Naïve Bayes; Bayesian Network; Classification; Clustering; Chow-Liu trees; Mathematical statistics; Matematisk statistik;

    Sammanfattning : It is rarely possible to use an optimal classifier. Often the classifier used for a specific problem is an approximation of the optimal classifier. Methods are presented for evaluating the performance of an approximation in the model class of Bayesian Networks. LÄS MER

  4. 19. On approximations and computations in probabilistic classification and in learning of graphical models

    Författare :Magnus Ekdahl; Jose Antonio Lozano; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; factorizations; probabilistic classification; nodes; DNA strings; Mathematical statistics; Matematisk statistik;

    Sammanfattning : Model based probabilistic classification is heavily used in data mining and machine learning. For computational learning these models may need approximation steps however. LÄS MER

  5. 20. Resource Base Change and Development during the Internationalization Process: The Case of a Swedish Fashion Firm

    Författare :Marissa Ekdahl; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; internationalization process; resources; capabilities; dynamic capabilities;

    Sammanfattning : This thesis examines the processes that define the change and development of a firm’s resources and capabilities during the internationalization process. Prior research shows that a firm’s resources and capabilities have an important impact on the internationalization process, either hindering or enabling it. LÄS MER
