Quantifying multifractal anisotropy in two dimensional objects
Rafał Rak, Stanisław Drożdż, Jarosław Kwapień +1
An efficient method of exploring the effects of anisotropy in the fractal properties of 2D surfaces and images is proposed. It can be viewed as a direction-sensitive generalization…
Multifractal organization of EEG signals in Multiple Sclerosis
Marcin Wątorek, Wojciech Tomczyk, Magda Gawłowska +9
Quantifying the complex/multifractal organization of the brain signals is crucial to fully understanding the brain processes and structure. In this contribution, we performed the m…
Genuine multifractality in time series is due to temporal correlations
Jarosław Kwapień, Pawel Blasiak, Stanisław Drożdż +1
Based on the mathematical arguments formulated within the Multifractal Detrended Fluctuation Analysis (MFDFA) approach it is shown that in the uncorrelated time series from the Gau…
Multiscale characteristics of the emerging global cryptocurrency market
Marcin Wątorek, Stanisław Drożdż, Jarosław Kwapień +3
The review introduces the history of cryptocurrencies, offering a description of the blockchain technology behind them. Differences between cryptocurrencies and the exchanges on wh…
Complexity in economic and social systems: cryptocurrency market at around COVID-19
Stanisław Drożdż, Jarosław Kwapień, Paweł Oświęcimka +2
Social systems are characterized by an enormous network of connections and factors that can influence the structure and dynamics of these systems. All financial markets, including…
Wavelet-based discrimination of isolated singularities masquerading as multifractals in detrended fluctuation analyses
Paweł Oświęcimka, Stanisław Drożdż, Mattia Frasca +4
The robustness of two widespread multifractal analysis methods, one based on detrended fluctuation analysis and one on wavelet leaders, is discussed in the context of time-series c…
