  1. 1. Virtual H&E Staining Using PLS Microscopy and Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Sally Vizins; Hanna Råhnängen; [2024]
    Nyckelord :Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

    Sammanfattning : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

  3. 2. Contrastive Multimodal Image Representations for Deformable Image Registration

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Love Nordling; [2022]
    Nyckelord :;

    Sammanfattning : Image registration is the process of finding correspondences between images of the same or of similar scenes. Multimodal image registration is the specific case where the images are captured with different imaging systems. LÄS MER

  4. 3. Mapping of Chromosome Dynamics over the Bacterial Cell Cycle

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Författare :Konrad Gras; [2018]
    Nyckelord :;

    Sammanfattning : The replication of DNA, its compaction and segregation in dividingcells are challenges which all organisms are faced with. Ensuringthat these processes occur without error is essential for thesurvival of the organism. LÄS MER

  5. 4. Novel Hybrid Nanomaterials : Combining Mesoporous Magnesium Carbonate with Metal-Organic Frameworks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Viktor Sanderyd; [2018]
    Nyckelord :Nanomaterials; Metal-Organic Frameworks; MOF; MMC; Porous; Mesoporous; Upsalite; Hybrid materials; Core-shell;

    Sammanfattning : Nanotechnology as a field has the potential to answer some of the major challenges that mankind faces in regards to environmental sustainability, energy generation and health care. Though, solutions to these concerns can not necessarily rely on our current knowhow. LÄS MER

  7. 5. Storage stability in a milk based UHT-beverage : effect of pH, carrageenan and storage time

    Master-uppsats, SLU/Dept. of Food Science

    Författare :Laura Pulkkinen; [2014]
    Nyckelord :UHT-milk; carrageenan; pH; casein micelles; bright field microscopy; confocal laser scanning microscopy; transmission electron microscopy; particle size; particle concentration;

    Sammanfattning : The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product’s intrinsic and extrinsic environment. LÄS MER
