A model for hand-over-hand motion of molecular motors
, 2008 A simple flashing ratchet model in two dimensions is proposed to simulate the hand-over-hand motion of two head molecular motors like kinesin. Extensive Langevin simulations of the model are performed.

Hidden geometric correlations in real multiplex networks
, 2016 Real networks often form interacting parts of larger and more complex systems. Examples can be found in different domains, ranging from the Internet to structural and functional brain networks.

A parity breaking Ising chain Hamiltonian as a Brownian motor
, 2014 We consider the translationally invariant but parity (left-right symmetry) breaking Ising chain Hamiltonian \begin{equation} {\cal H} = -U_2\sum_{k} s_{k}s_{k+1} - U_3\sum_{k} s_{k}s_{k+1}s_{k+3} \nonumber \end{equation} and let this system evolve by ...

Uniform asymptotic approximation of diffusion to a small target: Generalized reaction models [PDF]
, 2016 The diffusion of a reactant to a binding target plays a key role in many biological processes. The reaction radius at which the reactant and target may interact is often a small parameter relative to the diameter of the domain in which the reactant ...

Quantum field theory treatment of magnetic effects on a system of free electrons
, 2017 The effects of a magnetic field on the energy and on the spin of free electrons are computed in the framework of quantum field theory. In the case of a constant moderate field and with relatively slow electrons, the derived formulae are particularly ...

Towards Quantitative Classification of Folded Proteins in Terms of Elementary Functions
, 2010 A comparative classification scheme provides a good basis for several approaches to understand proteins, including prediction of relations between their structure and biological function. But it remains a challenge to combine a classification scheme that

Spin correlation function in 2D statistical mechanics models with inhomogeneous line defects
, 2010 We consider the critical spin-spin correlation function of the 2D Ising model with a line defect which strength is an arbitrary function of position. By using path-integral techniques in the continuum description of this model in terms of fermion fields,

, 2012 Folded proteins have a modular assembly. They are constructed from regular secondary structures like alpha-helices and beta-strands that are joined together by loops.
