  1. 1. Jamming and Soft-Core Rheology

    Författare :Daniel Vågberg; Peter Olsson; Teitel Stephen; Vitelli Vincenzo; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; jamming; rheology; soft matter; granular material; SLLOD; critical point; critical scaling;

    Sammanfattning : Many different physical systems, such as granular materials, colloids, foams and emulsions exhibit a jamming transition where the system changes from a liquid-like flowing state to a solid jammed state as the packing fraction increases. These systems are often modeled using soft-core particles with repulsive contact forces. LÄS MER

  3. 2. Brain parenchymal fraction in healthy individuals and in clinical follow-up of multiple sclerosis

    Författare :Mattias Vågberg; Anders Svenningsson; Richard Birgander; Jonathan Gilthorpe; Anne-Marie Landtblom; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain parenchymal fraction; Neurofilament light; Glial fibrillary acidic protein; Brain atrophy; Multiple Sclerosis; Clinical follow-up;

    Sammanfattning : Background Multiple sclerosis (MS) is an autoimmune disease characterised by inflammatory damage to the central nervous system (CNS). Accumulated CNS injury can be quantified as brain atrophy, definable as a reduction in brain parenchymal fraction (BPF). BPF correlate with disability in MS and is used routinely as an endpoint in clinical trials. LÄS MER

  4. 3. Quantitative MRI Biomarkers of Neurodegeneration in Multiple Sclerosis

    Författare :Michael Platten; Tobias Granberg; Chunliang Wang; Fredrik Piehl; Sara Shams; Mattias Vågberg; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Machine learning; Multiple sclerosis; Corpus callosum; Neurodegeneration; Medical Technology; Medicinsk teknologi;

    Sammanfattning : Background: Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative disease that targets myelin in the brain and spinal cord. The corpus callosum connects the cerebral hemispheres and is composed of heavily myelinated axons. LÄS MER
