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...

Is there a link between multifractal power law exponents and informational entropy in the CNS?

The Rényi’s entropy and the scale-free dimensions exhibit a straight relation, because the power law exponent n and the Rényi’s parameter β are correlated: changes in n lead to changes in β, and...

Brain and phase transitions: which is the role of fractals?

Many scientists claim that the default brain activity is in phase transition (charachterized by fractals) and that, during perceptions and higher thoughts, there is a bifurcation event and an exit...

The arrows of thermodynamics and of time: who comes first?

In our macroscopic Universe, the arrows of thermodynamics and of time have forced verses, e.g., towards an increase of entropy and a "positive" time. Is there a causal relationship between the...

Could the gravity be the missing link between noncommutative quantum mechanics and commutative relativity?

The unexploited unification of general relativity and quantum physics is a painstaking issue. Is it feasible to build a nonempty set, with a binary operation defined on it, that encompasses both...

The retina contains L cones, M cones and S cones: when they are activated, do they fire with the same frequency?

My question, in other words, is: when we see an object of different colours, does every colour cause the same frequency in the corresponding activated cone? Does every qualia (yellow, red and so...

Changes in probability p lead to changes in Shannon's entropy E. Is the reverse true? If I hypothetically change E, may I obtain a change in p?

Let's use an example. We have a function y = f(x), in which x is the input (the probability) and y is the output (the entropy). If we change y in y', can we find an x' such that f(x') = y'? In...
