Recurrence quantification analysis is a widely used method for characterizing patterns in time series. This article presents comprehensive survey conducting wide range of recurrence-based analyses to quantify the dynamical structure single and multivariate series, capture coupling properties underlying leader-follower relationships. The basics recurrence (RQA) all its variants are formally intr...

Abstract This study discusses the results of a Recurrence quantification analysis ( RQA ) Rössler system with fractional order $$q_1$$ q 1 derivative in first equation. The changes slightly range $$q_1 \in \langle 0.9,1.0\rangle$$ ∈ ⟨...

conclusions although the patients carrying m204i mutation were more likely to show lack of responses to lam therapy, lam replacing by other nucleoside/tide analogs plus hbig maybe still effective in decreasing hepatitis b recurrence after liver transplantation. however, it is suggested that drug resistance test should be considered by clinicians during therapeutic management to avoid the follow...

By means of the shift operators we introduce a new periodicity concept on time scales. This new approach will enable researchers to investigate periodicity notion on a large class of time scales whose members may not satisfy the condition there exists a P > 0 such that t± P ∈ T for all t ∈ T, which is being currently used. Therefore, the results of this paper open an avenue for the investigatio...

The characterization of the signals in terms of linear/ nonlinear and deterministic/stochastic nature may be appropriated for knowledge extraction and machine learning algorithms. Some real-world signals exhibit signal modality characteristics that are strongly related with the physical mechanisms involved in the production of them. As an example, we can mention how the resonant sounds are more...

Recurrence is a fundamental property of dynamical systems, which can be exploited to characterise the system’s behaviour in phase space.A powerful tool for their visualisation and analysis called recurrence plotwas introduced in the late 1980’s. This report is a comprehensive overview covering recurrence based methods and their applications with an emphasis on recent developments. After a brief...

It is sometimes difficult to differentiate between innocent murmurs and pathological murmurs during auscultation. In these difficult cases, an intelligent stethoscope with decision support abilities would be of great value. In this study, using a dog model, phonocardiographic recordings were obtained from 27 boxer dogs with various degrees of aortic stenosis (AS) severity. As a reference for se...

Takao Komatsu (Hirosaki Univ.) Four term leaping recurrence relations Elsner and Komatsu investigated linear three-term recurrence formulae Zn = T (n)Zn−1+U(n)Zn−2 (n ≥ 2) with sequences of integers {T (n)}n≥0 and {U(n)}n≥0, which are ultimately periodic modulo m. If U(n) 6= 0 for all n ≥ 0, then there exists a three-term leaping recurrence relation of the form W1Zrn+i+W2Zr(n−1)+i+ W3Zr(n−2)+i ...
