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

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

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

    Abstract : 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. READ MORE

  3. 2. A Conservative Discretization of a Hamiltonian System

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Robin Emanuelsson; [2018]
    Keywords : Physics and Astronomy;

    Abstract : The reaction–diffusion equation (RDE) is a natural way of describing a system where there is not only diffusion but also interaction with its surroundings. The RDE has been the topic of interest in previous papers for its usefulness of explaining pattern formations in nature. The static RDE has, in one dimension, the form of a Newton equation.

  4. 3. A Turing model for pattern generation on Lady beetles

    University essay from Lunds universitet/Matematik LTH

    Author : Erik Grandelius; [2016]
    Keywords : Turing model; reaction diffusion equation; Galerkin method; splitting scheme; Mathematics and Statistics;

    Abstract : A Turing model for pattern generation on Lady beetles is considered. This motivates the construction of numerical algorithms for solving reaction-diffusion equations on the sphere. By applying a Galerkin approximation in space, and the implicit Euler method for timestepping, the equation is fully discretized. READ MORE

  5. 4. An Explorative Parameter Sweep: Spatial-temporal Data Mining in Stochastic Reaction-diffusion Simulations

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Fredrik Wrede; [2016]
    Keywords : Big data; feature extraction; clustering; stochastic reaction-diffusion simulation; spatial-temporal; data mining; cloud computing;

    Abstract : Stochastic reaction-diffusion simulations has become an efficient approach for modelling spatial aspects of intracellular biochemical reaction networks. By accounting for intrinsic noise due to low copy number of chemical species, stochastic reaction-diffusion simulations have the ability to more accurately predict and model biological systems.

  6. 5. Computational Stochastic Morphogenesis

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Yakup Saygun; [2015]
    Keywords : computational morphogenesis; computational biology; biological pattern formation; stochastic simulations; stochastic Turing patterns; stochastic models; reaction-diffusion master equation; intrinsic noise; URDME; next subvolume method;

    Abstract : Self-organizing patterns arise in a variety of ways in nature, the complex patterning observed on animal coats is such an example. It is already known that the mechanisms responsible for pattern formation starts at the developmental stage of an embryo. However, the actual process determining cell fate has been, and still is, unknown. READ MORE
