Abduction and Deduction in Dynamical Cognitive Science. [PDF]

open access: yesTop Cogn Sci
Abstract This paper reviews the recent history of a subset of research in dynamical cognitive science, in particular that subset that allies itself with the sciences of complexity and casts cognitive systems as interaction dominant, noncomputational, and nonmodular. I look at this history in the light of C.S.

Altered Brain Criticality in Schizophrenia: New Insights From Magnetoencephalography

open access: yesFrontiers in Neural Circuits, 2022
Schizophrenia has a complex etiology and symptomatology that is difficult to untangle. After decades of research, important advancements toward a central biomarker are still lacking.

MULTIFRACTAL FLUCTUATIONS IN FINANCE [PDF]

open access: yesInternational Journal of Theoretical and Applied Finance, 2000
We consider the structure functions S(q)(τ), i.e. the moments of order q of the increments X(t + τ)-X(t) of the Foreign Exchange rate X(t) which give clear evidence of scaling (S(q)(τ)∝τζ(q)). We demonstrate that the nonlinearity of the observed scaling exponent ζ(q) is incompatible with monofractal additive stochastic models usually introduced in ...

What Can Multifractal Analysis Tell Us about Hyperspectral Imagery?

open access: yesRemote Sensing, 2020
Hyperspectral images provide complex information about the Earth’s surface due to their very high spectral resolution (hundreds of spectral bands per pixel).

Multifractality of quantum wave packets [PDF]

open access: yes, 2012
peer reviewedWe study a version of the mathematical Ruijsenaars-Schneider model and reinterpret it physically in order to describe the spreading with time of quantum wave packets in a system where multifractality can be tuned by varying a parameter.

Multifractal Analysis on the Sphere [PDF]

open access: yes, 2008
A new generation of instruments in astrophysics or vision now provide spherical data. These spherical data may present a self- similarity property while no spherical analysis tool is yet available to characterize this property. In this paper we present a first numerical study of the extension of multifractal analysis onto the sphere using spherical ...

Dual multifractal spectra [PDF]

open access: yesPhysical Review E, 2004
The multifractal formalism characterizes the scaling properties of a physical density rho as a function of the distance L. To each singularity alpha of the field is attributed a fractal dimension for its support f(alpha). An alternative representation has been proposed by Jensen considering the distribution of distances associated to a fixed mass ...

Multifractal Variation Measures and Multifractal Density Theorems

open access: yesReal Analysis Exchange, 2003
For \(E\subseteq {\mathbf R}^d, q, t\in {\mathbf R} \) and \(\delta >0\), \(\mathcal H_\mu^{q,t}\) and \(\mathcal P_\mu^{q,t}\) denote, respectively, the multifractal Hausdorff measure and multifractal packing measure introduced by Olsen and Peyrière.
