The gender and age profile of the migrants ensured the prolonged post-war demographic compensation and secured fertility and marriage rates above the RSFSR average. The regional fertility rates converged towards the national average in the second half of the 1950s; from the late 1970s, the region had a fertility rate below the national average. Overall mortality rates remained significantly ...
Models for countering the segregation of ethnoreligious immigrant areas in Denmark and Sweden

At the same time, the situation with the number of immigrants in Denmark has again become the opposite of Sweden. This is illustrated by the difference in asylum rates in both countries due to the increase in migration flows in the autumn of 2015. In Sweden, there were approximately 163,000 asylum claims (mostly from refugees from Syria, Afghanistan, and Iraq), while in Denmark their number was only 20,825.<5> ...

This paper aims to assess the transformation in consumer preferences in the Kaliningrad region under the influence of the food ...
Optimal parameters and sharp estimates of the convergence rate of the tangent expansion
In this paper we conceder the properties of the tangential incomplete block LU — decomposition. We present an analytical approach for determination of the optimal values of the decomposition parameter and derive sharp estimates of the convergence rate for a broad class of model problems. Numerical results prove that high convergence rate can be achieved by using these values also for the problems with varying coefficients.
