  1. 1. Solar variability over the Holocene period : disentangling geomagnetic and solar influences on a new continuous 10Be record from Little Dome C, Antarctica

    Författare :Hoang Long Nguyen; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ice core; cosmogenic radionuclide; 10Be; 14C; solar activity; paleomagnetism; ; Holocene;

    Sammanfattning : Reliable information on solar activity over the Holocene period is important to predict the Sun in the future and to understand the mechanism behind the Sun-climate linkage. Presently, there are discrepancies in the proxy data of solar activity due to reasons that are not yet understood. LÄS MER

  3. 2. Bayesian inference for high dimensional factor copula models

    Författare :Hoang Nguyen; Maria Conception Ausin Olivera; Pedro Galeano San Miguel; Universidad Carlos III de Madrid; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Copulas have been applied to many research areas as multivariate probability distributions for non-linear dependence structures. However, extending copula functions in high dimensions is challenging due to the increase of model parameters and computational intensity. LÄS MER

  4. 3. Gender specific epidemiology of tuberculosis in Vietnam

    Författare :Nguyên Hoàng Long; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Tuberculosis; epidemiology; gender; health care seeking; delays; Vietnam;

    Sammanfattning : Background: Globally, about two-thirds of notified tuberculosis (TB) cases are men, only one third are women. Whether this gender difference in notification rates reflects a true difference in TB incidence, or an under-notification of the disease among women is a subject to speculation. LÄS MER

  5. 4. Tissue regulation of dendritic cells : with focus on chemokines, function and migration

    Författare :Anh Thu Nguyen Hoang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tissue-specific cells, such as fibroblasts and epithelial cells in local microenvironments have been recognized to influence the function and phenotype of hematopoietic cells, such as dendritic cells (DC). The interaction and cooperation between DC and the cells of the tissue is important for the maintenance of immune homeostasis as well as orchestrating immune responses against pathogens. LÄS MER

  7. 5. Epidemiology of cardiovascular disease in rural Vietnam

    Författare :Hoang Van Minh; Peter Byass; Stig Wall; Nguyen Thi Kim Chuc; Cairns Smith; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; epidemiology; risk factors; rural Vietnam; Epidemiology; Epidemiologi;

    Sammanfattning : In the context of transitional Vietnam, although cardiovascular disease (CVD) has been shown to cause a large burden of mortality and morbidity in hospitals, little is known about the magnitude of its burden, risk factor levels and its relationship with socio-demographic status in the overall population. This thesis provides a preliminary insight into population-based knowledge of the CVD epidemiology in rural Vietnam and contributes to the development of methodologies for monitoring it. LÄS MER
