    Författare :Simon Benjaminsson; Anders Lansner; Marc-Oliver Gewaltig; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of three parts related to the in silico study of the brain: technologies for large-scale neural simulations, neural algorithms and models and applications in large-scale data analysis in neuroinformatics. All parts rely on the use of supercomputers. LÄS MER

  3. 2. Core-hole Clock Spectroscopy Using Hard X-rays : Exciting States in Condensed Matter

    Författare :Fredrik Johansson; Andreas Lindblad; Carla Puglia; Tomas Edvinsson; Marc Simon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core-hole clock; resonant Auger; XPS; black phosphorous; TMDC; perovskite; graphene; coincidences spectroscopy; synchrotron radiation; HAXPES;

    Sammanfattning : This thesis is about how electrons move from one place to another, that is charge transfer dynamics. Charge transfer dynamics is an important property governing chemical and physical changes that form the base for many applications such as electronics, optoelectronics and catalysis. LÄS MER

  5. 4. Oxygen sensing in Caenorhabditis elegans

    Författare :Lina Zhao; Changchun Chen; Simon Tuck; Helena Edlund; Marc Pilon; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; C. elegans; acute hypoxia; G-protein; mitochondrial ROS; neuropeptide; GPCR;

    Sammanfattning : Sufficient supply of oxygen (O2) to tissue is essential for survival of aerobicanimals. In mammals, there are constant homeostatic regulation mechanisms that act on different time scales to maintain optimal O2 delivery to tissues. The ability to detect and respond to acute oxygen shortages is indispensable to aerobic life. LÄS MER
