  1. 1. Genetic variation in two closely related salmonids, brown trout (Salmo trutta) and Atlantic salmon (Salmo salar) : a comparison of variability patterns and some management considerations

    Författare :Gunnar Ståhl; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Within the Salmonidae, a wide range of intraspecific variation, both morphological and ecological, has long been recognized. In the present study electrophoresis was used to examine natural populations of brown trout (Salmo trutta) and Atlantic salmon (Salmo solar) in northern Sweden in an effort to reveal the genetic structure of these populations.

  2. 2. Integrating domain knowledge into deep learning : Increasing model performance through human expertise

    Författare :Niclas Ståhl; Göran Falkman; Alexander Karlsson; Gunnar Mathiason; Jonas Boström; Keith Downing; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; INF301 Data Science; INF301 Data Science; Skövde Artificial Intelligence Lab SAIL ; Skövde Artificial Intelligence Lab SAIL ;

    Sammanfattning : The research in this thesis is focused on how deep learning models can be designed and implemented to better emulate and integrate the heuristic reasoning process of human experts. Several case studies, within the domains of steel making and drug discovery, are conducted in order to evaluate the performance of these models, in comparison to models that do not consider human expert knowledge from the targeted domain.

  3. 3. Array-based Genomic and Epigenomic Studies in Healthy Individuals and Endocrine Tumours

    Författare :Johanna Sandgren; Gunnar Westin; Teresita Diaz de Ståhl; Göran Åkerström; Ola Hessman; Winand Dinjens; Uppsala universitet; []
    Nyckelord :genome; copy number variants; cancer; Pheochromocytoma; epigenome; array-CGH; ChIP-chip; gene expression; tumour suppressor genes; oncogenes; MEDICINE; MEDICIN; Kirurgi; Surgery;

    Sammanfattning : The human genome is a dynamic structure, recently recognized to present with significant large-scale structural variation. DNA-copy number changes represent one common type of such variation and is found both between individuals and within the somatic cells of the same individual, especially in disease states like cancer.

  4. 4. An evaluation of regional sustainability by analysing energy and carbon flows – A study of Jämtland, Sweden

    Författare :Torbjörn Skytt; Bengt-Gunnar Jonsson; Fredrik Ståhl; Magdalena Svanström; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Regional sustainability; Energy flows; Exergy; Carbon GHG fluxes; Sustainability indicators; carbon dioxide emissions; methane emissions; nature emissions;

    Sammanfattning : Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. LÄS MER
