Magnetic nanoparticles for therapy and diagnosis are at the leading edge of the rapidly developing field of bionanotechnology. In this study, we have theoretically studied motion of magnetic nano- as well as micro-particles in the field of cylindrical Halbach array of permanent magnets. Magnetic flux density was modeled as magnetostatic problem by finite… (More)
A new approach is proposed to model a collective ion channel dynamics. We have assumed that ion channels create a two-component spatio-temporal interaction field. Every channel at its current spatial location in membrane contributes permanently to this field with its state (open or closed) and coupling strength to other channels. This field is described by… (More)
Novel method for the global characterization of time series, based on the calculation of fractal dimension of a two-dimensional recurrence plots is proposed. The method is used for the characterization of differences between regular and chaotic systems and for the analysis of human electrocardiogram.
