The measurement of the field radiated from an antenna placed above a finite ground plane experiences the effects of the field scattered by the edges of the ground plane. A new numerical method to remove these effects from measured data is presented here. It resorts to the image theorem and can be used for both near-field and far-field measurements. A simple and effective algorithm has been deve...

The paper gives a new method for analyzing planar discontinuities in rectangular waveguides. The method consists of a re-expansion of the normal modes in the two ducts at the junction plane into a system of functions accounting for the velocity singularities at the corner points. As the new expansion has an exponential convergence, only a few terms have to be considered for obtaining the soluti...

This paper develops and implements a new algorithm for calculating wave trace invariants of a bounded plane domain around a periodic billiard orbit. The algorithm is based on a new expression for the localized wave trace as a special multiple oscillatory integral over the boundary, and on a Feynman diagrammatic analysis of the stationary phase expansion of the oscillatory integral. The algorith...

A new test-system was developed for rapid evaluation of the cytoprotective potential of substances which can be included in cosmetics and health care compositions. It was evaluated by changes of the viability of yeast cells after dehydration/rehydration (D/R) treatment. To check the efficiency of proposed test system we studied the effects of water extracts of the natural peloid, which are used...

People with epilepsy (PWE), particularly those with more severe seizures, are at risk of premature death. The contribution of deaths unrelated to epilepsy to this risk is likely to be significant. Recent studies indicate that comorbid conditions are similarly increased in PWE. The reason for these increases in unrelated deaths and comorbid conditions is unclear. In this article, we argue that h...

A theoretical description of nucleon knockout reactions initiated by polarized electron scattering from polarized nuclei is presented. Explicit expressions for the complete set of reduced response functions (independent of the polarization angle) that can be experimentally obtained assuming plane waves for the electron are given in a general multipole expansion. The formalism is applied to the ...

The mode expansion offers a general framework for the analysis of the interaction between antennas and propagation channels. In this paper, the Mean Effective Gain (MEG) of an antenna is expressed in terms of the spherical vector wave expansion of the electromagnetic field. An explicit expression of the MEG is provided as a function of the normalized average power of modes excited in the propag...

The Protestant work ethic (PWE), the belief that hard work leads to success, is prevalent in many cultures and has been related to negative attitudes toward disadvantaged groups (prejudice) and social policies targeting them. Given recent theorizing and findings suggesting that PWE is not necessarily associated with prejudice among all people or in all contexts, this meta‐analysis examined the ...
