    Genome instability is a common feature of most cancer types. DNA damage is an important source of genome instability wherein DNA double strand breaks (DSBs) are particularly genotoxic as both strands of the DNA molecule are severed, risking loss ...
  • Aach, Marcel (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2025-01)
    The design of Deep Learning (DL) models is a complex task, involving decisions on the general architecture of the model (e.g., the number of layers of the Neural Network (NN)) and on the optimization algorithms (e.g., the learning rate). These so-called ...
  • Oswaldo (University of Iceland, Faculty of Pharmaceutical Sciences, School of Health Sciences, 2024-09)
    The goal of this project was to contribute to the pharmaceutical development of CN03, the lead candidate for drug treatment of retinitis pigmentosa (RP) and other inherited retinal degenerations (IRDs). RP is an inherited neurodegeneration of the retina ...
  • Sigurpálsson, Ásgeir Örn (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2025-01-31)
    Demographic change, increasing cost of care, and shortage of hospital workers pose challenges in hospital management. As a response, hospitals maintain high utilisation of their existing resources by maximising patient throughput to minimise waiting ...
  • Kazemi, Masoumeh (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2025-01)
    The present thesis is devoted to a theoretical analysis of optical excitonic response and magnetic lattice dynamics in two-dimensional materials, in particular monolayers of CrI3 . Combining the results of DFT and Bethe-Salpeter simulations ...
  • de la Cámara, Marina (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2025-01)
    Exploring the genetic basis of ecological diversification is crucial to understand how diversity is generated and maintained. The overall aim of this thesis is to disentangle the genetic basis behind the ecological differentiation of the Arctic charr ...
