Extended detrended fluctuation analysis and its applications
A.A. Koronovskii Jr., A.N. Pavlov (Saratov State University)
Abstract
To quantify short-term reactions associated with transients, we propose an extension of the conventional DFA approach, which estimates an additional scaling exponent reflecting the effect of nonstationarity. We study scaling features in the reactions of cereral blood vessel network to sudden “jumps”in peripheral arterial pressure in rats. Based on statistical analysis, we report significant distinctions in the responses of small network of microcerebral blood vessels compared to veins such as the sagittal sinus, which are quite insensitive to variations in peripheral blood circulation.
