In order to study the creep characteristics of concrete under different temperatures, the uniaxial creep test of concrete is carried out. On this basis, the nonlinear creep model of concrete is established by using the fractal order derivative theory. According to the characteristics of the classica...

We prove lower bounds on the density of regular minimal cones of dimension less than seven provided the complements of the cones are topologically nontrivial.

The article deals with the categories of "stereotype" and "identity" that make up the core of the national culture. The authors proceed from the assumption that the stereotypes that have arisen in the course of historical development create a cliche for the perception of both one...
