Randomly forced DNA.
We study the effect of random forces on a double-stranded DNA in unzipping the two strands, analogous to the problem of an adsorbed polymer under a random force. The ground state develops bubbles of various lengths as the random force fluctuation is increased. The unzipping phase diagram is shown to be drastically different from the pure case.
متن کاملAttractors of a randomly forced electronic
This paper examines an electronic oscillator forced by a pseudo-random noise signal. We give evidence of the existence of one or more random at-tractors for the system depending on noise amplitude and system parameters. These random attractors may appear to be random xed points or random chaotic attractors. In the latter case, we observe a form of intermittent synchronization of the response of...
متن کاملAlmost Periodically Forced Circle Flows
We study general dynamical and topological behaviors of minimal sets in skewproduct circle flows in both continuous and discrete settings, with particular attentions paying to almost periodically forced circle flows. When a circle flow is either discrete in time and unforced (i.e., a circle map) or continuous in time but periodically forced, behaviors of minimal sets are completely characterize...
متن کاملOn oscillating flows in randomly heterogeneous porous media.
The emergence of structure in reactive geofluid systems is of current interest. In geofluid systems, the fluids are supported by a porous medium whose physical and chemical properties may vary in space and time, sometimes sharply, and which may also evolve in reaction with the local fluids. Geofluids may also experience pressure and temperature conditions within the porous medium that drive the...
متن کاملMonte Carlo simulations of the randomly forced Burgers equation
The behaviour of the one–dimensional random–forced Burgers equation is investigated in the path integral formalism, using a discrete space–time lattice. We show that by means of Monte Carlo methods one may evaluate observables, such as structure functions, as ensemble averages over different field realizations. The regularization of shock solutions to the zero–viscosity limit (Hopf-eq.) eventua...
