We point out that, due to the nonlinearity of the Einstein equations, a homogeneous approximation in cosmology leads to the appearance of an additional term in the Friedmann equation. This new term is associated with the ...

The rapid advance of gravitational wave (GW) detector facilities makes it very important to estimate the event rates of possible detection candidates. We consider an additional possibility of GW bursts produced during ...

We calculated the weak localization correction to the density of the transmission eigenvalues in the case of chaotic quantum dots in the framework of random matrix theory including the parametric dependence on the magnetic ...

Traffic modeling of communication networks such as the Internet has become a very important field of research. A number of interesting phenomena are found in measurements and traffic simulations. One of them is the propagation ...

We introduce an effective scalar field theory to describe the He4 phase diagram, which can be considered as a generalization of the XY model which gives the usual λ transition. This theory results from a Ginzburg-Landau ...
