Final-state sensitivity in a system with intermingled basins is investigated. Under a scaling assumption a dimension of the basins, referred to as the conditional external dimension, is introduced by which the uncertainty exponent is expressed. For a

A two-dimensional piecewise linear mapping is introduced as a solvable model to characterize the multifractal structure of an intermingled basin. To this end, we make use of the multifractal formalism and introduce a partition function. The singulari

With a model for two-dimensional (2D) Brownian rotary ratchets being capable of producing a net torque under athermal random forces, its optimization for mean angular momentum ($L$), mean angular velocity ($\ensuremath{\omega}$), and efficiency ($\en

The sine-circle map driven by noise with bounded amplitude is shown to be a model exhibiting the characteristics of chaotic phase synchronization (CPS). Two different routes to CPS corresponding to the observation by Osipov et al. are also explained

Following Fujisaka's basic idea, large deviation statistics characterizing temporal fluctuations are calculated based on Mori's projection-operator method. It is shown that this calculation will overcome the finite-sample effect studied by Nakao et a

The response to a time periodic treatment of the immunotherapy in a stochastic model of tumor-immune interaction is numerically investigated. Due to the effect of synchronization among the intrinsic oscillation and the treatment, an enhanced extincti

Various synchronizations and related phenomena in discrete-time coupled chaotic rotors are studied. For unidirectional and bidirectional couplings, various dynamical forms of chaotic phase synchronization (CPS) and their relation to the Lyapunov spec

A time-delayed feedback control to stabilize a swinging motion of magnetic moment in a single-domain magnetic system under AC field is studied. The system has a uniaxial anisotropy, and the AC field is parallel to this. Without control, it prefers th
Within the context of the Brownian ratchet model, a molecular rotary system was studied that can perform unidirectional rotations induced by linearly polarized ac fields, and produce positive work under loads. The model is based on the Langevin equat

As a stochastic model of chaotic phase synchronization (CPS), a phase dynamics driven by dichotomous Markov noise is proposed. The master equation is analytically solved for the rotation number and the phase diffusion constant as the characteristics
