  1. 6. End-to-End Learning of Deep Structured Models for Semantic Segmentation

    Författare :Måns Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semantic segmentation; deep structured models; supervised learning; convolutional neural networks; conditional random fields;

    Sammanfattning : The task of semantic segmentation aims at understanding an image at a pixel level. This means assigning a label to each pixel of an image, describing the object it is depicting. LÄS MER

    Författare :Helena Johansson; Göteborgs universitet; []
    Nyckelord :osteoporosis; fracture; bone mineral density; ; clinical risk factors; FRAX; Poisson model; 10 year probability; mortality; vitamin D; adiponectin;

    Sammanfattning : Introduction: Osteoporosis has been recognised as an established and well-defined disease that affects more than 75 million people in the United States, Europe and Japan. Osteoporosis has been operationally defined by the WHO on the basis of bone mineral density (BMD) assessment. LÄS MER

  4. 8. HIV disease progression - Impact of HIV-1 intersubtype recombination and association with HIV-2 evolution

    Författare :Angelica Palm; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) are both causative agents of AIDS, with similar pathogenic characteristics. However, the rate of disease progression is highly variable both within and between HIV-1 and HIV 2, but the mechanisms involved in modulating the rate of disease progression remain poorly understood.

  5. 9. HIV-1 infection of the central nervous system. Markers of pathogenesis and antiretroviral treatment effects

    Författare :Sahra Abdulle; Göteborgs universitet; []
    Nyckelord :HIV-1; cerebrospinal fluid; antiretroviral therapy; neopterin; beta2-microglobulin; CSF HIV-1 RNA; blood-brain barrier; IgG index; HIV-related neurological diseases; AIDS Dementia Complex; neurofilament protein; HIV-1 genetic subtypes;

    Sammanfattning : Human immunodeficiency virus type 1 (HIV-1) invades the central nervous system (CNS) early in the course of infection and either directly or through opportunistic infections causes a spectrum of neurological complications. The most severe manifestation of HIV-1 CNS infection is AIDS Dementia Complex (ADC), which occurs in approximately 20% of untreated patients with AIDS. LÄS MER
