In this paper, we consider analytically the density evolution of a spinless Fermi liquid with nonlinear dispersion relation into which one particle is injected. The interaction point-like and temperature zero. We obtain formula for discuss picture it gives as well physics behind it. Compared to case linear spectrum, find further more complex fractionalization initial hump: splits three humps in...

venturi flumes are measurement structures commonly used in water systems to measure the flow discharge. some of them are not well installed or present some geometrical defects. the objective of this study is to investigate the hydraulic influence of a number of typical wrong installations and geometrical defects of long-throated venturi flumes: significant positive or adverse slopes, humps and ...

It is well known that pulselike solutions of the cubic complex Ginzburg-Landau equation are unstable but can be stabilized by the addition of quintic terms. In this paper we explore an alternative mechanism where the role of the stabilizing agent is played by the parametric driver. Our analysis is based on the numerical continuation of solutions in one of the parameters of the Ginzburg-Landau e...

RXJ0501.7–0359 is a new V ∼ 17mag eclipsing polar discovered during the ROSAT all-sky survey (RASS). Extensive follow-up observations at X-ray (pointed ROSAT PSPC and HRI observations) and optical (time-resolved photometry and spectroscopy) wavelengths were obtained which allowed us to determine a very precise orbital period and to provide constraints for the masses of the binary components and...

Periodic and solitary travelling-wave solutions of an extended reduced Ostrovsky equation are investigated. Attention is restricted to solutions that, for the appropriate choice of certain constant parameters, reduce to solutions of the reduced Ostrovsky equation. It is shown how the nature of the waves may be categorized in a simple way by considering the value of a certain single combination ...

A detailed analysis, based on kinetic and fluid simulations, of striation phenomenon in the plasma display panel cell has been presented. Numerical studies indicate that the phenomenon of striation occurs primarily due to the accumulation of space charge near the anode electrode. These space charges locally create multiple-layer potential distribution near the anode region. The ion density in t...
