1. Diffusion in fractal globules
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Recent experiments suggest that the human genome (all of our DNA) is organised as a so-called fractal globule. The fractal globule is a knot--free dense polymer that easily folds and unfolds any genomic locus, for example a group of nearby genes. Proteins often need to locate specific target sites on the DNA, for instance to activate a gene. LÄS MER
2. A Brief Survey of Lévy Walks : with applications to probe diffusion
Kandidat-uppsats, Institutionen för kemiSammanfattning : Lévy flights and Lévy walks are two mathematical models used to describe anomalous diffusion(i.e. those having mean square displacements nonlinearly related to time (as opposed to Brownian motion)). Lévy flights follow probability distributions p(|r|) yielding infinite mean square displacements since some rare steps are very long. LÄS MER
3. Normal and anomalous diffusion
Master-uppsats, Fakulteten för teknik- och naturvetenskapSammanfattning : Diffusion can be classified as either normal or anomalous. A variety of experimental systems are evaluated to classify diffusion. Potential regressions and step size distributions are analysed. LÄS MER
