May bifurcation diagrams exhibit the parameter "time" on the x-axis?

When plotting a bifurcation diagram in nonlinear dynamics, the axis x displays a given phase parameter. Are there examples in which the phase parameter stands for time passing (for example, from...

Is the Klein j-invariant (or j-function) a fractal?

Some modular functions, such as the Riemann zeta one, display a fractal behaviour. Does also the curve of the j-function display power law properties, or a scale free structure? It it feasible...

Transcranial stimulation: is the role of fractals in the waveforms underestimated?

We suggest that the techniques of transcranial electrical stimulation need to be keept into account, along with the amplitude and frequency of the applied waveforms (Reato), and also their scaling...
