  2. 21. Measuring brain functions : statistical tests for neuroimaging data

    Author : Anders Ledberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis is about statistical methods for functional neuroimaging data. With functional neuroimaging, here understood as PET and fMRI, the activity of the human brain can be studied in vivo. READ MORE

  4. 22. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression

    Author : Ali Tofigh; Jens Lagergren; Mike Steel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lateral Gene Tranfer; Horizontal Gene Transfer; Cancer Progression; Bioinformatics; Bioinformatik; Computer science; Datalogi;

    Abstract : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.

  5. 23. Evolutionary Approaches to Sequence Alignment

    Author : Marcin Bogusz; Simon Whelan; Jeffrey Thorne; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular evolution; multiple sequence alignment; pair hidden Markov models; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Molecular evolutionary biology allows us to look into the past by analyzing sequences of amino acids or nucleotides. These analyses can be very complex, often involving advanced statistical models of sequence evolution to construct phylogenetic trees, study the patterns of natural selection and perform a number of other evolutionary studies.

  6. 24. The Socialization of Intergroup Attitudes : The Problem of Generations

    Author : David Ekstam; Gina Gustavsson; Anders Westholm; Mikael Hjerm; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Socialization; intergroup attitudes; cohort analysis; generational replacement; age effects; Statskunskap; Political Science;

    Abstract : This doctoral thesis regards long-term aggregate trends in intergroup attitudes and the individual-level mechanisms that underlie change and continuity on the aggregate-level. The thesis focusses primarily on attitudes toward homosexuality in the North American context and attitudes toward immigration in the European context. READ MORE

  7. 25. On testing and forecasting in fractionally integrated time series models

    Author : Michael K. Andersson; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This volume contains five essays in the field of time series econometrics. All five discuss properties of fractionally integrated processes and models. The first essay, entitled Do Long-Memory Models have Long Memory?, demonstrates that fractional integration can enhance the memory of ARMA processes enormously. READ MORE
