Hidden Markov model analysis of multichromophore photobleaching

Article Abstract:

Multiple interacting components are investigated by using multiply labeled dextran polymers that are intentionally photobleached to the background on a single-molecule basis and the hidden Markov models allows for unsupervised analysis of the data. The general utility of this method is discussed for determining aggregation-state distributions as could appear in many biologically important systems and its adaptability to general photometric experiments.

Markovian approximation in the relaxation of open quantum systems

Article Abstract:

The validity of the Markovian approximation and the slippage scheme used to incorporate short time transient memory effects in the Markovian master equations are examined. The reduced dynamics obtained from the non-Markovian master equation for all parameters studied while the simple slippage scheme breaks down at high temperatures.
