Heat Kernel Expansion for Operators of the Type of the Square Root of the Laplace Operator [PDF]
A method is suggested for the calculation of the DeWitt-Seeley-Gilkey (DWSG) coefficients for the operator $\sqrt{-\nabla^2 + V(x)}$ basing on a generalization of the pseudodifferential operator technique.

A parametric study on buckling of R/C columns exposed to fire [PDF]
Buckling of concrete columns is a major issue in fire design, since heating of the columns will result in loss of stiffness and strength in the outer concrete layers.

Application of the calculation method for calculating an economically justified land tax
The article considers the mechanism used to calculate the land tax. caused by the overestimation by the state of the cadastral value of land plots used as a tax base, which leads to the problem of economically unreasonable taxation for taxpayers.

Finite amplitude method for the RPA solution [PDF]
We propose a practical method to solve the random-phase approximation (RPA) in the self-consistent Hartree-Fock (HF) and density-functional theory. The method is based on numerical evaluation of the residual interactions utilizing finite amplitude of ...
