  1. 16. Hic2 overexpression increase of cell reprogramming efficiency- a computational study

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Paulina Ibek; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Since stem cells have many applications in medicine and can be used for treating e.g. cancer and diabetes, finding efficient methods for producing them is a relevant area of research. READ MORE

  3. 17. Generalized super-resolution of 4D Flow MRI : extending capabilities using ensemble learning

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Adam Hjalmarsson; Leon Ericsson; [2023]
    Keywords : 4D Flow MRI; Ensemble learning; Super-resolution; Machine learning; Neural networks; 4DFlowNet;

    Abstract : 4D Flow Magnet Resonance Imaging (4D Flow MRI) is a novel non-invasive technique for imaging of cardiovascular blood flow. However, when utilized as a stand-alone analysis method, 4D Flow MRI has certain limitations including limited spatial resolution and noise artefacts, motivating the application of dedicated post-processing tools.

  4. 18. Simulation of Quantum Cascade Lasers

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Zakaria Mohamed; [2023]
    Keywords : Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Abstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE

  5. 19. The Bloch-Messiah theorem and its application to overlaps

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Frieder Selisko; [2023]
    Keywords : Physics and Astronomy;

    Abstract : The Bogoliubov transformation is the starting point for the Hartree-Fock-Bogoliubov method and thus for many theoretical approaches that describe heavy nuclei. This transformation is based on two matrices, denoted by U and V, which are called Bogoliubov amplitudes. In this paper the properties of these matrices are investigated. READ MORE

  6. 20. Adaptive random walks on graphs to sample rare events

    University essay from Stockholms universitet/Fysikum

    Author : David Christoph Stuhrmann; [2023]
    Keywords : statistical physics; graphs; random walks; large deviation theory; adaptive power method; dynamical phase transition;

    Abstract : In this thesis, I study fluctuations and rare events of time-additive observables of discrete-time Markov chains on finite state spaces. The observable of interest is the mean node connectivity visited by a random walk running on instances of an Erdős-Rényi (ER) random graph. READ MORE
