Twenty-two promising wheat varieties were studied for their plant height, length of filament, size of anther, number of pollen grains/anther and the extent of pollen shed outside the florets. Plantâ€¦ (More)

Solution of the boundary value problem for optimal escape in continuous stochastic systems and maps.

A numerical technique is introduced that reduces exponentially the time required for Monte Carlo simulations of nonequilibrium systems. Results for the quasistationary probability distribution in twoâ€¦ (More)

We study fluctuational transitions between two co-existing chaotic attractors separated by a fractal basin boundary in a discrete dynamical system. It is shown that the mechanism of fluctuationalâ€¦ (More)

We study fluctuational transitions in a discrete dynamical system having two co-existing attractors in phase space, separated by a fractal basin boundary. It is shown that transitions occur via aâ€¦ (More)

We study fluctuational transitions in a discrete dynamical system that has two co-existing attractors in phase space, separated by a fractal basin boundary which may be either locally-disconnected orâ€¦ (More)

Fluctuational escape via an unstable limit cycle is investigated in stochastic flows and maps. A new topological method is suggested for analysis of the corresponding boundary value problems when theâ€¦ (More)
