1. 1. Diffusion in fractal globules

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jakob Hariz; [2016]
   Keywords : Fractal Globule; Anomalous Diffusion; Diffusion; DNA;

   Abstract : 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. READ MORE

3. 2. A Brief Survey of Lévy Walks : with applications to probe diffusion

   University essay from Institutionen för kemi

   Author : Lars Fredriksson; [2010]
   Keywords : Fluorescence; Probe; diffusion; Lévy walks; Brownian;

   Abstract : 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. READ MORE

4. 3. Normal and anomalous diffusion

   University essay from Fakulteten för teknik- och naturvetenskap

   Author : Lars Fredriksson; [2010]
   Keywords : anomalous diffusion; latex; fluorescence; probes; anisotropic; isotropic;

   Abstract : 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. READ MORE
