Microbial characterization based on multifractal analysis of metagenomes [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
IntroductionThe species diversity of microbiomes is a cutting-edge concept in metagenomic research. In this study, we propose a multifractal analysis for metagenomic research.Method and ResultsFirstly, we visualized the chaotic game representation (CGR ...

A bivariate multifractal analysis approach to understanding socio-spatial segregation dynamics [PDF]

open access: yesScientific Reports
Although the study of multifractal properties is now an established approach for the statistical analysis of urban data, the joint multifractal analysis of several spatial signals remains largely unexplored.

Characterization of nanofluids using multifractal analysis of a liquid droplet trace [PDF]

open access: yesScientific Reports, 2022
The article presents an innovative approach to the analysis of nanofluids using a nonlinear multifractal algorithm. The conducted research concerned nanofluids prepared from SiO2 nanoparticles (~ 0.01 g) suspended in 100 ml of demineralized water and in ...

Bootstrap for Multifractal Analysis [PDF]

open access: yes2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
Multifractal analysis, which mainly consists in estimating scaling exponents, has become a popular tool for empirical data analysis. Although widely used in different applications, the statistical performance and the reliability of the estimation procedures are still poorly known.

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 ...

MULTIFRACTAL CROSS WAVELET ANALYSIS [PDF]

open access: yesFractals, 2017
Complex systems are composed of mutually interacting components and the output values of these components usually exhibit long-range cross-correlations. Using wavelet analysis, we propose a method of characterizing the joint multifractal nature of these long-range cross correlations, a method we call multifractal cross wavelet analysis (MFXWT).

Multifractal analysis for nutritional assessment. [PDF]

open access: yesPLoS ONE, 2013
The concept of multifractality is currently used to describe self-similar and complex scaling properties observed in numerous biological signals. Fractals are geometric objects or dynamic variations which exhibit some degree of similarity (irregularity ...

Multifractal analysis of mass function. [PDF]

open access: yesSoft comput, 2023
In order to explore the fractal characteristic in Dempster-Shafer evidence theory, a fractal dimension of mass function is proposed recently, to reveal the invariance of scale of belief entropy. When mass function degenerates to probability, the fractal dimension is equivalent to classical Renyi information dimension only with α=1, which can measure ...

Relationships of exponents in multifractal detrended fluctuation analysis and conventional multifractal analysis

open access: yesChinese Physics B, 2011
Multifractal detrended fluctuation analysis (MF-DFA) is a relatively new method of multifractal analysis. It is extended from detrended fluctuation analysis (DFA), which was developed for detecting the long-range correlation and the fractal properties in stationary and non-stationary time series.
