In this paper we introduce techniques for efficient multicast video streaming in UMTS networks where a video content has to be conveyed to multiple users in the same cell.Efficient multicast data delivery in UMTS is still an open issue.In particular, suitable solutions have to be found to cope with wireless channel errors, while maintaining both an

We introduced a class of spiraling elliptic hollow beams with the cross phase.Due to the cross phase, the spiraling elliptic hollow beams exhibit three key characteristics, having the elliptic peak ring, carrying the orbital angular momentum (OAM), and performing rotations.We investigated both linear and nonlinear evolutions of the spiraling ellipt

Viral infections provoke dysbalance in the interferon system and wella color charm 050 cooling violet inhibition of the cellular and phagocytic responses of the host.Long-term persistence of pathogenic viruses and bacteria induce atopy and could aggravate chronic respiratory diseases.The up-to-date classification of immunomodulators cocktail tree f

In spite of their potential usefulness, Wigner functions for systems with SU(1,1) symmetry have not been explored thus far.We address this problem from a physically-motivated perspective, with an eye towards applications in modern metrology.Starting from two independent modes, and after getting rid of the irrelevant degrees of freedom, we derive in

This paper nyx 22 brush presents the results of a study that sheds new light on the shape of indifference curves in the Marschak-Machina triangle.The most important observation, obtained non-parametrically, concerns jumps in indifference curves at the triangle legs towards the triangle origin.These jumps, however, do not appear at the hypotenuse.Th
