Within the framework of massive $\mathrm{O}(N)$ nonlinear sigma model extended to next-to-leading order in chiral counting [for $N=3$ corresponding two(-quark)-flavor Chiral Perturbation Theory], we calculate relativistic six-pion scattering amplitude at low energy up and including terms $\mathcal{O}({p}^{4})$. Results for pion mass, decay constant, four-pion case $N$ (meson) flavors $\mathcal{...

Model nanocontacts formed at a gold–HOPG interface exhibit complex frictional behavior with variety of phenomena, from thermolubricity to superlubricity and exotic sliding dynamics.

In the present paper, the problem of reflection and transmission of waves at an interface of elastic and microstretch thermoelastic solids with microtemperatureshas been studied. The amplitude ratios of various reflected and transmitted waves are functions of angle of incidence and frequency of incident wave. The expressions of amplitude ratios have been computed numerically for a particular mo...

This paper concentrates on the reflection of plane waves in the mixture of generalized thermo elastic solid half-space. There exists quasi dilatational waves i.e. qP1, qP2, qT and two rotational waves S1, S2 in a two dimensional model of the solid. The boundary conditions are solved to obtain a system of five non-homogeneous equations for amplitude ratios. These amplitude ratios are found to de...

This paper introduces the indicators for surge arrester condition assessment based on the leakage current analysis. Maximum amplitude of fundamental harmonic of the resistive leakage current, maximum amplitude of third harmonic of the resistive leakage current and maximum amplitude of fundamental harmonic of the capacitive leakage current were used as indicators for surge arrester condition mon...
