Angular Properties of Transport in Random Media
By exploring the properties of angles in single trajectories we can quite efficiently deduce the underlying stochastic mechanism. While a dull quantity for regular diffusion, its behavior becomes quite rich for any complex movement.
Using ergodicity and biasing to increase precision
This figure summarizes a simple argument that is used in order to increase a precision of tracking algorithm. Incorporating ergodicity of the tracked process and systematic “wrong” tracking of singlemolecule leads to precision (in estimation of molecule position) beyond the limit of un-biased estimation.
