Based on the morphological analysis techniques developed under the guidance of Yu.P. Pyt’ev, a method for filtering time series is proposed that is capable of detecting an almost cyclic component with a varying cycle length and varying series membe

The goal of the present study was to identify the possible disturbances in the synchronization of spontaneous fluctuations in arterial pressure (AP) and heart rate (HR) at the frequency of baroreflex waves (~0.1 Hz) in patients prone to vasovagal fai

The monotonicity of the CABARET scheme approximating the quasi-linear scalar conservation law with a convex flux is analyzed. The monotonicity conditions for this scheme are obtained in the areas where the propagation velocity of the characteristics

An explicit combined shock-capturing finite-difference scheme is constructed that localizes shock fronts with high accuracy and simultaneously preserves the high order of convergence in all domains where the computed weak solutions are smooth. In thi

Monotonicity conditions for the CABARET scheme approximating a quasilinear scalar conservation law with a convex flux are obtained. It is shown that the monotonicity of the CABARET scheme for Courant numbers $$r \in (0.5,1]$$ does not ensure the comp

In this paper, a splitting method for a CABARET scheme approximating a nonuniform scalar conservation law with a convex and monotonically increasing flux function is proposed. It is shown that at the first step of this method, when a uniform conserva

We present here a case report of recurring fainting due to orthostatic hypotension in a 45‑year-old woman with Hodgkin's' disease, treated by radiation therapy and resection of cervical lymph node. We discuss difficulties of identification of etiol

It is demonstrated that the standard flow-variables’ correction required for the monotonicity of the CABARET scheme reduces its accuracy near local extrema. A modified correction of the flows is proposed; it retains the strong monotonicity of the C

The monotonicity of the CABARET scheme approximating a scalar conservation law with a convex flux is analyzed. Monotonicity conditions for this scheme are obtained assuming that the propagation velocity of characteristics of the approximated conserva
