Approaching Bounded Rationality: From Quantum Probability to Criticality (open access)

Approaching Bounded Rationality: From Quantum Probability to Criticality

This article discusses the decision-making model (DMM), a paradigmatic instance of criticality, which deals with bounded rationality issues in a similar way as quantum probability (QP), generating choices that cannot be accounted by classical probability (CP). This work may contribute to considering criticality as another possible fundamental pillar in order to improve the understanding of cognition and of quantum mechanics.

The Fractal Tapestry of Life: III Multifractals Entail the Fractional Calculus (open access)

The Fractal Tapestry of Life: III Multifractals Entail the Fractional Calculus

This article is the third essay advocating the use the (non-integer) fractional calculus (FC) to capture the dynamics of complex networks in the twilight of the Newtonian era. Herein, the focus is on drawing a distinction between networks described by monfractal time series extensively discussed in the prequels and how they differ in function from multifractal time series, using physiological phenomena as exemplars.
