  1. 1. Digital Image Analysis of Cells : Applications in 2D, 3D and Time

    Författare :Amalka Pinidiyaarachchi; Carolina Wählby; Ewert Bengtsson; Arvid Lundervold; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital image analysis; microscopy; fluorescent staining; watershed segmentation; sub-cellular localization; point-like signals; wavelets; cell confluence; cytology; color spaces.; Image analysis; Bildanalys;

    Sammanfattning : Light microscopes are essential research tools in biology and medicine. Cell and tissue staining methods have improved immensely over the years and microscopes are now equipped with digital image acquisition capabilities. The image data produced require development of specialized analysis methods. LÄS MER

  3. 2. Methods and models for 2D and 3D image analysis in microscopy, in particular for the study of muscle cells

    Författare :Patrick Karlsson Edlund; Ewert Bengtsson; Joakim Lindblad; Carolina Wählby; Fritz Albregtsen; Uppsala universitet; []
    Nyckelord :medical image analysis; image segmentation; fluorescence microscopy; cytometry; human skeletal muscle;

    Sammanfattning : Many research questions in biological research lead to numerous microscope images that need to be evaluated. Here digital image cytometry, i.e., quantitative, automated or semi-automated analysis of the images is an important rapidly growing discipline. LÄS MER

  4. 3. Hybrid Plasmonics for Energy Harvesting and Sensing of Radiation and Heat

    Författare :Mina Shiran Chaharsoughi; Magnus Jonsson; Xavier Crispin; Simone Fabiano; Eunkyoung Kim; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The special optical properties of subwavelength metallic structures have opened up for numerous applications in different fields. The interaction of light with metal nanostructures leads to the excitation of collective oscillations of conduction-band electrons, known as plasmons. LÄS MER

  5. 4. Methods for 2D and 3D Quantitative Microscopy of Biological Samples

    Författare :Amin Allalou; Carolina Wählby; Ida-Maria Sintorn; Ewert Bengtsson; Jens Rittscher; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image analysis; cytmetry; model organism; zebrafish; screening; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : New microscopy techniques are continuously developed, resulting in more rapid acquisition of large amounts of data. Manual analysis of such data is extremely time-consuming and many features are difficult to quantify without the aid of a computer. LÄS MER

  7. 5. Indirect Searches for Dark Matter in the Milky Way with IceCube-DeepCore

    Författare :Martin Wolf; Chad Finley; Maurizio Spurio; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark Matter Annihilation; WIMP; Milky Way; IceCube Neutrino Observatory; DeepCore; neutrino; particle physics; high-energy physics; fysik; Physics;

    Sammanfattning : Many astronomical observations, including rotational curve measurements of stars and the analysis of the cosmic microwave background, suggest the existence of an invisible matter density content in the Universe, commonly called Dark Matter (DM). Possibly, DM could be of particle nature, where Weakly Interacting Massive Particles (WIMPs) could be a viable DM candidate. LÄS MER
