Recurrence quantification analysis during a mental calculation task

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2023
The identification of brain dynamical changes under different cognitive conditions with noninvasive techniques such as electroencephalography (EEG) is relevant for the understanding of their underlying neural mechanisms. The comprehension of these mechanisms has applications in the early diagnosis of neurological disorders and asynchronous brain ...

RECURRENCE QUANTIFICATION ANALYSIS: INTRODUCTION AND HISTORICAL CONTEXT

International Journal of Bifurcation and Chaos, 2007
Although chaotic systems continue to gain interest, their confirmation and analysis can be difficult. Traditional analytic methods impose constraints which are often difficult to achieve. A technique which does not impose these constraints is recurrence quantification analysis.

Quantification analysis of fuzzy recurrence plots

Europhysics Letters, 2022
Abstract The method of fuzzy recurrence plots has been introduced as an extension of the method of recurrence plots to display recurrences of the reconstructed phase-space trajectories of dynamical systems as grayscale images. This paper presents some quantifiable measures of fuzzy recurrence plots in the context of the recurrence ...

Sleep-wake detection using recurrence quantification analysis

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2018
Actigraphy is a method for monitoring the movements of the nondominant arm, and the technology has found applications ranging from clinical devices to smart wristbands. Time series obtained from actigraphy data is used in chronobiology to define the sleep-wake cycle, as well as in sleep medicine to evaluate an individual’s sleep quality.

Recurrence Quantification Analysis: Theory and Applications

2021
Complex systems are characterized by deterministic laws (which often may be hidden) and randomness. A tool to analyse those systems is recurrence quantification analysis (RQA). RQA does not rely on any sort of assumption of stationarity and is not sensitive to singularities and transitions.

Multiscale recurrence quantification analysis of order recurrence plots

Physica A: Statistical Mechanics and its Applications, 2017
Abstract In this paper, we propose a new method of multiscale recurrence quantification analysis (MSRQA) to analyze the structure of order recurrence plots. The MSRQA is based on order patterns over a range of time scales. Compared with conventional recurrence quantification analysis (RQA), the MSRQA can show richer and more recognizable information ...

Recurrence quantification analysis of speech

The Journal of the Acoustical Society of America, 2006
A time-series analysis technique known as recurrence quantification analysis (RQA) holds promise as a new method for investigating the dynamical properties of the acoustic speech signal. RQA was created to deal with complex time series generated by high-dimensional, nonlinear dynamical systems.

Recurrence Quantification and Recurrence Network Analysis of Global Photosynthetic Activity

2014
In this chapter, the potential of Recurrence Analysis (RA) for applications in the biogeosciences is demonstrated. We investigate the fraction of absorbed photosynthetically active radiation (FAPAR), an index based on multispectral reflectance properties of land surfaces which relates to the carbon uptake by plants.

Recurrence quantification analysis of global stock markets [PDF]

open access: possiblePhysica A: Statistical Mechanics and its Applications, 2011
This study investigates the presence of deterministic dependencies in international stock markets using recurrence plots and recurrence quantification analysis (RQA). The results are based on a large set of free float-adjusted market capitalization stock indices, covering a period of 15 years.

Recurrence plots and recurrence quantification analysis of human motion data

AIP Conference Proceedings, 2016
The authors present exemplary application of recurrence plots, cross recurrence plots and recurrence quantification analysis for the purpose of exploration of experimental time series describing selected aspects of human motion. Time series were extracted from treadmill gait sequences which were recorded in the Human Motion Laboratory (HML) of the ...
