  1. 6. Non-perturbative models of diffractive hadronic collisions

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Edgars Karnickis; [2022]
    Nyckelord :diffractive process; proton-proton collision; elastic; parton; PDF; saturation; Physics and Astronomy;

    Sammanfattning : In this thesis, a new model for diffractive proton-proton collisions is presented. Interpreting protons as systems of many partons, we treat diffraction in terms of elastic interactions between the partons of the colliding protons. LÄS MER

  3. 7. Diffusion and Camera-Noise Modelling for Analysis of Single-Particle Tracking Movies

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Erik Clarkson; [2022]
    Nyckelord :reaction-diffusion; camera-noise modelling; single-particle tracking; Gillespie simulations; Physics and Astronomy;

    Sammanfattning : Interactions between T-cells and other body cells is an essential part of the immune system. It involves the binding between surface receptors of the two cells. Specifically, T-cell receptors (TCRs) bind onto pMHC (peptide-loaded major histocompatibility complex) molecules on the partnering cell surface. LÄS MER

  4. 8. Measuring Acoustic Mobility of Particles by Particle Tracking Velocimetry

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Alexander Edthofer; [2022]
    Nyckelord :acoustophoresis; microfluidics; polystyrene; cells; particle tracking velocimetry; Technology and Engineering;

    Sammanfattning : Acoustophoresis is a method to manipulate and move cells or particles suspended in a medium using acoustic waves. The speed of the acoustophoretic motion depends on the cells' acoustic mobility, i.e. their size, density and compressibility relative to the medium. LÄS MER

  5. 9. Calculating scattering amplitudes in φ3 and Yang-mills theory using perturbiner methods

    L3-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Daniel Nilsson; Magnus Bertilsson; [2022]
    Nyckelord :QFT; Quantum; Quantum field theory; scattering amplitudes; Berends Giele Currents; feynman diagrams; n particle scattering;

    Sammanfattning : We calculate tree-level scattering amplitudes in φ^3 theory and Yang-Mills theory by means of the perturbiner expansion. This involves solving the Euler-Lagrange equations of motion perturbatively via a multi-particle ansatz, and using Berends-Giele recursion relations to extract the solution from simple on-shell data.

  7. 10. Polarizability and Orientation Dynamics of Small Proteins

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Ebba Koerfer; [2022]
    Nyckelord :Protein orientation; single-particle imaging; polarizability; orientation dynamics; rigid rotor model;

    Sammanfattning : Proteins often carry an intrinsic electric dipole moment, which can interact with external electric fields and cause protein motion. Previous research has found that the orientation of small proteins in gas phase can be controlled in a static electric field. LÄS MER
