  3. 2. Cell Identification from Microscopy Images using Deep Learning on Automatically Labeled Data

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Fredrik Salomon-Sörensen; [2023]
    Keywords : Deep Learning; Cell Identification; Image Segmentation; Nuclei Segmentation; Convolutional Neural Networks; UNet; Image Analysis; Microscopy; Noisy Labels; Phase-Contrast; Automatic Labeling; Technology and Engineering;

    Abstract : In biology, cell counting provides a fundamental metric for live-cell experiments. Unfortunately, most researchers are constrained to using tedious and invasive methods for counting cells. Automatic identification of cells in microscopy images would therefore be a valuable tool for such researchers. READ MORE

  4. 3. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Sara Falk; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE

  6. 5. Effects of plastic pollution on leaf litter decomposition in Swedish freshwater ecosystems : a field study addressing recently and globally emerging pollutants

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Martina Stangl; [2022]
    Keywords : Microplastics; Face masks; Ecosystem functioning; Leaf decomposition; Field study;

    Abstract : Plastic pollution is recognized as an increasing environmental problem, but few studies have addressed impacts on ecosystem functions, and very few have been conducted in the field. This study investigated the effects of polypropylene particles derived from disposable face masks on in-situ leaf litter decomposition processes in freshwater ecosystems. READ MORE
