Review of Some Promising Fractional Physical Models [PDF]

open access: yes, 2015
Fractional dynamics is a field of study in physics and mechanics investigating the behavior of objects and systems that are characterized by power-law non-locality, power-law long-term memory or fractal properties by using integrations and ...

Extreme phase sensitivity in systems with fractal isochrons [PDF]

open access: yes, 2015
Sensitivity to initial conditions is usually associated with chaotic dynamics and strange attractors. However, even systems with (quasi)periodic dynamics can exhibit it.

The Smoothness of Fractal Interpolation Functions on ℝ and on p-Series Local Fields

open access: yesDiscrete Dynamics in Nature and Society, 2014
A fractal interpolation function on a p-series local field Kp is defined, and its p-type smoothness is shown by virtue of the equivalent relationship between the Hölder type space CσKp and the Lipschitz class Lipσ,Kp. The orders of the p-type derivatives

Stochastic models which separate fractal dimension and Hurst effect [PDF]

open access: yes, 2001
Fractal behavior and long-range dependence have been observed in an astonishing number of physical systems. Either phenomenon has been modeled by self-similar random functions, thereby implying a linear relationship between fractal dimension, a measure ...

Complexity in the scaling of velocity fluctuations in the high-latitude F-region ionosphere [PDF]

open access: yesAnnales Geophysicae, 2008
The temporal scaling properties of F-region velocity fluctuations, δvlos, were characterised over 17 octaves of temporal scale from τ=1 s to <1 day using a new data base of 1-s time resolution SuperDARN radar measurements.

Weighted Estimates on fractal domains [PDF]

open access: yes, 2015
The aim of the paper is to establish estimates in weighted Sobolev spaces for the solutions of the Dirichlet problems on snowflake domains, as well as uniform estimates for the solutions of the Dirichlet problems on pre-fractal approximating ...

Analysis of a Fractal Boundary: The Graph of the Knopp Function

open access: yesAbstract and Applied Analysis, 2015
A usual classification tool to study a fractal interface is the computation of its fractal dimension. But a recent method developed by Y. Heurteaux and S.

Alterations of peripheral cytokines, BDNF, and surface-based morphometry indices in T2DM patients without cognitive impairment

open access: yesFrontiers in Neuroscience, 2023
PurposeThis study aimed to investigate potential biological mechanisms underlying cognitive function alterations in Type 2 diabetes mellitus (T2DM) patients by integrating cortical morphology with peripheral cytokine levels and brain-derived neurotrophic

Fractal dimension and degree of order in sequential deposition of mixture

open access: yes, 1997
We present a number models describing the sequential deposition of a mixture of particles whose size distribution is determined by the power-law $p(x) \sim \alpha x^{\alpha-1}$, $x\leq l$ .
