  1. 1. Adaptive Semi-structured Information Extraction

    Författare :Anders Arpteg; Erik Sandewall; Wlodek Kulesza; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information extraction; Artificial intelligence; Semi-structured data; Reinforced learning; Knowledge management; Computer science; Datavetenskap;

    Sammanfattning : The number of domains and tasks where information extraction tools can be used needs to be increased. One way to reach this goal is to construct user-driven information extraction systems where novice users are able to adapt them to new domains and tasks. LÄS MER

  3. 2. Feedback Enhancement of Antibody Responses via Complement and Fc Receptors

    Författare :Jörgen Dahlström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Mouse; transgenic knockout; immune regulation; B lymphocytes; Fc receptors; complement; IgG; IgM; IgE; Fc-gamma-RI; Fc-gamma-RII; Fc-gamma-RIII; CR1; CR2; CD21; CD35; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : IgG, IgM and IgE in complex with antigen have the capacity to regulate specific immune responses. In this investigation, the role of Fc receptors for IgG (FcγRI, FcγRII and FcγRIII) and complement receptors 1 and 2 (CR1/2) for antibody-mediated enhancement of antibody responses are investigated.

  4. 3. Cell-Specific Ca2+ Response in Pancreatic ß-cells

    Författare :Natalia Gustavsson; Per Lindström; Peter Bergsten; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heterogeneity; individual ß-cells; islets of Langerhans; cytoplasmic calcium; repetitive glucose stimulation; lag-time; cell-specific; glyceraldehyde; ketoisocaproic acid; tolbutamide; mitochondrial metabolism; Histology; Histologi;

    Sammanfattning : Pancreatic ß-cells are heterogeneous in their secretory responsiveness, glucose sensitivity and metabolic rate. A diminished and delayed first-phase insulin release is an early sign of failing ß-cells in diabetes. LÄS MER

  7. 5. Analysis of Human Brain MRI : Contributions to Regional Volume Studies

    Författare :Richard Nordenskjöld; Joel Kullberg; Elna-Marie Larsson; Lars Johansson; Håkan Ahlström; Göran Starck; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Brain; Volume; Hemisphere; Intracranial volume; Image analysis; Computerized Image Analysis; Datoriserad bildanalys;

    Sammanfattning : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. LÄS MER
