Ancient human genomes suggest three ancestral populations for present-day Europeans
Iosif Lazaridis, Nick Patterson, Alissa Mittnik +117
We sequenced genomes from a 7,000 year old early farmer from Stuttgart in Germany, an 8,000 year old hunter-gatherer from Luxembourg, and seven 8,000 year old hun…
Splitting schemes for poroelasticity and thermoelasticity problems
A. E. Kolesov, P. N. Vabishchevich, M. V. Vasilyeva
In this work, we consider the coupled systems of linear unsteady partial differential equations, which arise in the modeling of poroelasticity processes. Stability estimates of wei…
Explicit schemes for parabolic and hyperbolic equations
Petr N. Vabishchevich
Standard explicit schemes for parabolic equations are not very convenient for computing practice due to the fact that they have strong restrictions on a time step. More promising e…
Numerical solving the identification problem for the lower coefficient of parabolic equation
P. N. Vabishchevich, V. I. Vasil'ev
In the theory and practice of inverse problems for partial differential equations (PDEs) much attention is paid to the problem of the identification of coefficients from some addit…
Mathematical modeling of thermal stabilization of vertical wells on high performance computing systems
Natalia V. Pavlova, Petr N. Vabishchevich, Maria V. Vasilyeva
Temperature stabilization of oil and gas wells is used to ensure stability and prevent deformation of a subgrade estuary zone. In this work, we consider the numerical simulation of…
