In this paper, the progress in the theoretical study of the dielectric barrier discharge is reported. The model of the atmospheric-pressure discharge is discussed. Such effects as the oscillations of the Townsend mode of the discharge, the instability of the Townsend mode with subsequent transition to the filamentary discharge, and the stabilization of the barrier discharge by the photoemission...

The valence photoelectron spectrum has been measured for molecular KBr. Experimental energies of the main and satellite structures have been ompared with the results of ab initio calculations based on molecular orbital theory including configuration and multiconfiguration interaction pproaches. Comparison between the experimental KBr spectrum and previously reported Kr valence photoelectron spe...

In this paper different methods supporting a new intensity formula in optical emission spectroscopy are presented. Three independent experimental and analytical methods have been developed which strongly support this new formula. Different light sources have also been used in this work. A new theory has earlier also been presented which strongly verify the new formula. Support is also given fro...

We show that photoelectron spectromicroscopy with synchrotron radiation has been successfully exported from materials science to the life sciences. The transfer is well beyond mere feasibility tests. Photoelectron spectromicroscopy is in fact used for real, long-term studies in neurobiology. Specific examples are discussed, first to see in practice some applications to microchemical analysis of...

Newly obtained photoelectric V magnitudes for three galaxies in Shakhbazian I, when combined with the virial analysis of Robinson and Wampler, show that the cluster mass-to-luminosity ratio is WL ~ 4. The first brightest galaxy in the cluster (an elliptical) has (U—B) and (B—V) color indices which are consistent with those of normal ellipticals in the Virgo and Coma clusters, and it is suggeste...

We discuss streaking time delays for photoemission from solid model surfaces as a function of the degree of the initial-wave-function localization and including the dynamical plasmon response to the motion of the photoelectron.

So on average, a woman with more than two kids works 6 weeks fewer than her counterpart with fewer than 2 kids. The result changes a little after we include age as the regressor. The question is, does this correlation imply causality? So the key regressor is morekids. The main concern is that morekids may be endogenous, i.e., correlated with the error term, due to simultaneity or omitted variab...
