Specific Features of Calculating the Radiant Component of the Heat Flow of Horizontal Bunch from Finned Tubes with Exhaust Shaft by A. B. Sukhotski, G. S. Marshalova, Е. S. Danil’chik

“…The system of equations describing the entire set of primary processes that make up the radiation heat exchange of finned bundles is very complex mathematically; therefore, the calculations of radiant heat transfer are usually based on a number of simplifying assumptions with a involuntarily distortion of the real physical picture. The main methods for calculating radiation used in engineering practice, viz. calculation by the average angular coefficient and the zonal method are briefly considered. …”

Features of survival analysis on patients on the «waiting list» for kidney transplantation by A. B. Zulkarnaev

“…Since competing events are censored, it is impossible to directly assess the impact of covariates on their frequency, because there is no direct relationship between the regression coefficients and the intensity of these events. The determination of the median waiting time on the basis of such analysis generates a selection bias, which inevitably leads to a biased assessment. …”
