  1. 16. Approaches to Species Delineation in Anamorphic (mitosporic) Fungi : A Study on Two Extreme Cases

    Författare :Olga Vinnere; Siv Andersson; Jamshid Fatehi; Berndt Gerhardson; Stephen B. Goodwin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; fungal taxonomy; Colletotrichum acutatum; Mycelia Sterilia; Phoma; Campanella; phylogeny; species concept in fungi; Biologi; Biology; Biologi;

    Sammanfattning : Since the beginning of mycology, studies of species concept in fungi have been mainly based on morphology, partially due to the history of mycology as part of botany. Current advances in biochemical and molecular research have provided mycologists with powerful tools that can be used for delineation of fungal taxa. LÄS MER

  3. 17. Representation learning for natural language

    Författare :Olof Mogren; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; artificial neural networks; artificial intelligence; natural language processing; deep learning; machine learning; summarization; representation learning;

    Sammanfattning : Artificial neural networks have obtained astonishing results in a diverse number of tasks. One of the reasons for the success is their ability to learn the whole task at once (endto-end learning), including the representations for data. LÄS MER

  4. 18. Periarticular changes in association with osteoarthritis in the hip, knee or shoulder

    Författare :Mustafa Ibrahim; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; Tendinopathy; Bone mineral density;

    Sammanfattning : The aim of this thesis was to evaluate the presence of degenerative changes in the periarticular tendons in association with osteoarthritis (OA) in the hip, knee or shoulder. Moreover, changes in bone mineral density (BMD) in the hip, spine and calcanei were investigated after total hip arthroplasty (THA). LÄS MER

  5. 19. Phylogenetic Studies in Usnea (Parmeliaceae) and Allied Genera

    Författare :Kristina Articus; Leif Tibell; Mats Wedin; Jan-Eric Mattsson; Philippe Clerc; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Usnea; Neuropogon; Dolichousnea; Eumitria; Protousnea; Parmeliaceae; phylogeny; taxonomy; species pairs; morphology; ITS-LSU; β-tubulin; mtSSU; Biologi; Biology; Biologi;

    Sammanfattning : This thesis deals with the phylogeny of the lichen genus Usnea (Parmeliaceae, Ascomycetes). The relationships and the morphological variation among Usnea species has been studied, as well as the relationship of Usnea to allied genera. Two species, U. florida and U. LÄS MER

  7. 20. Biodiversity and genetic patterns in marine invertebrates

    Författare :Emma Vodoti; Göteborgs universitet; []
    Nyckelord :zoology; marine biodiversity;

    Sammanfattning : Abstract: Systematics based on genetic data has both confirmed and contradicted earlier, morphologically defined species and their relatedness. Morphology does not always correspond to genetic lineages, and this will inevitably affect both traditional systematics as well as biodiversity assessments. LÄS MER
