Publikováno v: Europhys. Lett. 83, 20004-p1-p6 (2008)

The diffusion process of N hard rods in a 1D interval of length L (--> inf) is studied using scaling arguments and an asymptotic analysis of the exact N-particle probability density function (PDF). In the class of such systems, the universal scaling

Toolbox for analyzing finite two-state trajectories

Autor: Flomenbom, O., Silbey, R. J.

Publikováno v: Phys. Rev. E 78, 066105 (2008)

In many experiments, the aim is to deduce an underlying multi-substate on-off kinetic scheme (KS) from the statistical properties of a two-state trajectory. However, the mapping of a KS into a two-state trajectory leads to the loss of information abo

Path probability density functions for semi-Markovian random walks

Autor: Flomenbom, O., Silbey, R. J.

Publikováno v: Phys. Rev. E 76, 041101 (2007)

In random walks, the path representation of the Green's function is an infinite sum over the length of path probability density functions (PDFs). Here we derive and solve, in Laplace space, the recursion relation for the n order path PDF for any arbi

Single Stranded DNA Translocation Through a Fluctuating Nanopore

Autor: Flomenbom, O., Klafter, J.

Publikováno v: J.T. Fourkas, P. Levitz, M. Urbakh, K.J. Wahl Eds. Dynamics in Small Confining Systems, MRS Proceedings (Boston, 2003)

We investigate the translocation of a single stranded DNA (ssDNA) through a pore, which fluctuates between two conformations, by using coupled master equations (ME). The probability density function (PDF) of the first passage times (FPT) of the trans

Insight into Resonant Activation in Discrete Systems

Autor: Flomenbom, O., Klafter, J.

Publikováno v: Phys. Rev. E 69, 051109 (2004).

The resonant activation phenomenon (RAP) in a discrete system is studied using the master equation formalism. We show that the RAP corresponds to a non-monotonic behavior of the frequency dependent first passage time probability density function (pdf

Translocation of a Single Stranded DNA Through a Conformationally Changing Nanopore

Autor: Flomenbom, O., Klafter, J.

Publikováno v: Biophys. J. 86: 3576-3584 (2004)

We investigate the translocation of a single stranded DNA through a pore which fluctuates between two conformations, using coupled master equations. The probability density function of the first passage times (FPT) of the translocation process is cal

Single Stranded DNA Translocation Through A Nanopore: A Master Equation Approach

Autor: Flomenbom, O., Klafter, J.

Publikováno v: Phys. Rev. E 68, 041910 (2003)

We study voltage driven translocation of a single stranded (ss) DNA through a membrane channel. Our model, based on a master equation (ME) approach, investigates the probability density function (pdf) of the translocation times, and shows that it can
