In this paper, we present the Expert Hub System, which was designed to help governmental structures find the best experts in different areas of expertise for better reviewing of the incoming grant proposals. In order to define the areas of expertise with topic modeling and clustering, and then to relate experts to corresponding areas of expertise and rank(More)
Shifting towards smart citizenship means more cooperation between the state and every citizen. eHealthcare is a good example of such cooperation -- when the way to reach healthy population starts in the mind of every individual. Modern social environment is overwhelmed by symbolic occasions, however the popularity of some issues may become beneficial both(More)
We studied the effects of hypoxic, hypercapnic, and hypercapnic-hypoxic exposures on brain tolerance to ischemia. All respiratory training modes had a neuroprotective effect, but the most pronounced effect was observed after exposure to hypercapnic hypoxia. Experimental stroke in rats preliminary exposed to hypercapnic hypoxia was associated with minimal(More)
The evaluation problem of transient processes was considered from the viewpoint of their exponential convergence, as a criterion of system stability. To evaluate the exponential convergence, Lyapunov exponents are used. There was developed a number of procedures to evaluate the first Lyapunov exponent based on time series, as the attractor exponential(More)
Intermittent hypercapnic hypoxia was accompanied by increases in cerebral vascular resistance, decreases in the reactivity of cerebral vessels to hypercapnia, and increases in the collateral reserve and rate of autoregulation of brain blood flow. These changes were an important component of the mechanism increasing the tolerance of the brain to ischemia in(More)
