We analyze the laser ellipticity dependence of n-photon differential cross sections (dσn/dΩ) for electron-atom scattering in an intense elliptically polarized laser field. We show that there exist two plateau-like structures in the dependence of dσn/dΩ on n for any ellipticity, including for the case of circular polarization. We present numerical predictions for e-H scattering in a CO2-laser fi...

We report discovery of actively star forming elliptical galaxies in a morphologically classified sample of bright galaxies at a low redshift obtained from the Sloan Digital Sky Survey. The emission lines of these galaxies do not show the characteristics of active galactic nuclei, and thus their strong Hα emission is ascribed to star formation with a rate nearly as high as that is seen in typica...

Dielectric metasurfaces supporting quasibound states in the continuum (quasi‐BICs) exhibit very high‐quality factor resonances and electric field confinement. However, accessing high‐Q end of quasi‐BIC regime usually requires marginally distorting metasurface design from a BIC condition, pushing needed nanoscale fabrication precision to limit. This work introduces novel concept for generating q...

In a previous work, a mechanism was presented by which Baryon asymmetry can be generated during inflation from elliptically polarized gravitons. Nonetheless, the mechanism only generated a realistic baryon asymmetry under special circumstances which requires an enhancement of the lepton number from an unspecified GUT. In this note we provide a stringy embedding of this mechanism demonstrating t...

A big issue in the task of annotating multimedia data about dialogs and associated gesture and emotional state is due to the great variety of intrinsically heterogeneous metadata and to the impossibility of a standardization of the used descriptor in particular for the emotional state of the subject. We propose to tackle this problem using the instruments and the vision offered by Semantic Web ...

In this paper, we consider more general forms of generalized vector quasi-equilibrium problems for multivalued maps which include many known vector quasi-equilibrium problems and generalized vector quasi-variational inequality problems as special cases. We establish some existence results for solutions of these problems under pseudomonotonicity and u-hemicontinuity/ -hemicontinuity assumptions.
