Higher Conformal Multifractality

Journal of Statistical Physics, 2003
We derive, from conformal invariance and quantum gravity, the multifractal spectrum f(alpha,c) of the harmonic measure (or electrostatic potential, or diffusion field) near any conformally invariant fractal in two dimensions, corresponding to a conformal field theory of central charge c.

Neuromodulatory Systems

Frontiers in Neural Circuits, 2013
We examine the interactions and interdependencies between Neuroglia, the Brain-Cell Microenvironment, and the processes commonly subsumed under Neuromodulation.

Analogy between turbulence and quantum gravity: beyond Kolmogorov's 1941 theory

, 2011
Simple arguments based on the general properties of quantum fluctuations have been recently shown to imply that quantum fluctuations of spacetime obey the same scaling laws of the velocity fluctuations in a homogeneous incompressible turbulent flow, as ...

Multifractal Fluctuations in Seismic Interspike Series

, 2005
Multifractal fluctuations in the time dynamics of seismicity data have been analyzed. We investigated the interspike intervals (times between successive earthquakes) of one of the most seismically active areas of central Italy by using the Multifractal ...

A Mathematical Review and Improvement of the Multifractal Analysis

IEEE Access
This article presents a focused mathematical study of multifractal analysis, building on previous applications to reservoir rock characterization. Here, we revisit the theoretical foundations by summarizing key multifractal measures and classification ...

Generalized Hurst exponent and multifractal function of original and translated texts mapped into frequency and length time series

, 2012
A nonlinear dynamics approach can be used in order to quantify complexity in written texts. As a first step, a one-dimensional system is examined : two written texts by one author (Lewis Carroll) are considered, together with one translation, into an ...

Multifractal analysis of the perimeters of glaciers in the Svalbard Archipelago

Journal of Physics: Complexity
The investigation of the evolution of glaciers largely relies on the characterisation of extensive quantities like their mass, area, and perimeter.

Analysis of spatial structure and singularity of microbial biogeochemical anomalies in the Taiwan Strait Basin

Frontiers in Marine Science
The abundance of specific hydrocarbon-oxidizing bacteria (MV value) in surface soil is closely linked to the concentration of thermogenic light hydrocarbons found in the underlying layers.
