  1. 1. Computational Aspects of Maass Waveforms

    Författare :Fredrik Strömberg; Dennis A. Hejhal; Andreas Strömbergsson; David Farmer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Maass waveform; Congruence subgroup; Noncongruence subgroup; Multiplier system; Theta multiplier system; Eta multiplier system; real weight; Hecke operator; Involution; Dirichlet character; Spectral Theory; Computation; Matematisk analys; Mathematical analysis; Analys; matematik; Mathematics;

    Sammanfattning : The topic of this thesis is computation of Mass waveforms, and we consider a number of different cases: Congruence subgroups of the modular group and Dirichlet characters (chapter 1); congruence subgroups and general multiplier systems and real weight (chapter 2); and noncongruence subgroups (chapter 3). In each case we first discuss the necessary theoretical background. LÄS MER

  3. 3. Smooth Schubert varieties and boolean complexes of involutions

    Författare :Vincent Umutabazi; Axel Hultman; Jan Snellman; Volodymyr Mazorchuk; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is composed of two papers both in algebraic combinatorics and Coxeter groups.In Paper I, we concentrate on smoothness of Schubert varieties indexed by involutions from finite simply laced types. LÄS MER

  4. 4. Early effects of castration therapy in non-malignant and malignant prostate tissue

    Författare :Nina Ohlson; Pernilla Wikström; Anders Bergh; Pär Stattin; Marja Nevalainen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; human biopsies; androgen ablation; stroma; epithelium; micro-dissection; PSA; IGF-1; IGF-R1; AR; Pathology; Patologi;

    Sammanfattning : Early Effects of Castration Therapy in Non-malignant and Malignant Prostate Tissue BACKGROUND. Androgen ablation, the standard treatment for advanced prostate cancer, results in increased apoptosis, decreased cell proliferation and subsequent involution of the prostate gland. LÄS MER

  5. 5. Dynamic changes in T cell compartments and new approaches in evaluating DSS induced and Gai2 deficient colitis

    Författare :Maria Fritsch Fredin; Göteborgs universitet; []
    Nyckelord :colitis; Gai2- - mice; dextran sodium sulfate; ex vivo cultures; micro-Computed Tomography; IEL; thymus; Inflammatory Bowel Disease;

    Sammanfattning : The overall aim of this thesis was to increase the understanding of the immunopathology of Inflammatory Bowel Disease (IBD). The first aim was to elucidate how the thymus and the gut epithelium were affected by colitis. The second aim was to investigate new ways of assessing and monitoring colitis. LÄS MER
