The following acoustic characteristics are measured in this study: the velocity of longitudinal waves Cl and the attenuation coefficient of ultrasound δ in samples of grey cast iron, which are obtained by centrifugal casting. The correlations betwee

The spatial dynamics of ring dark solitary waves is studied numerically in order to determine the appropriate initial conditions for an effective control of their transverse velocity. We show that the evolution of the solitary-wave parameters radius,

Guiding of multiple signal beams in an induced all-optical cable is studied theoretically. A balance relation is derived for the interaction geometry and undistorted propagation of bright elliptical signal beams nested in a single ring dark soliton.

We present experimental results on the evolution of ring dark solitary waves and optical vortices generated by computer-synthesized holograms. The detailed comparative numerical simulations show, that this approach ensures reproduction of the correct

Antithrombin III is one of the most important inhibitors of serine proteases of coagulation and fibrinolysis. It inhibits the activity of thrombin and factor X. Its congenital or acquired reduction leads to an increased risk of thrombosis. In their s

A detailed study on yellow conical emission observed in dense sodium vapor following near-resonant one-photon excitation of the Na 42P levels was performed. The origins of conical emission are suggested to be due to Raman resonant four-wave parametri
