The Lorentz-Dirac equation of motion for the electron is derived by a new method which makes tedious power series expansions unnecessary. Copyright © 1975 American Institute of Physics.

Four-fermion operators have been utilized in the past to link the quarkexchange processes in the interaction of hadrons with the effective mesonexchange amplitudes. In this paper, we apply the similar idea of Fierz ...

Magnetism It is the property that bodies have called magnets attract iron, nickel and cobalt. Its importance in very large as it is used in ringers, alarm switches, motors, spacers metal bodies, etc.

Imaging is possible by crossing fundamental rays, which occur when the objects reflected in mirrors, the formed images are real, virtual, and right reversed, depending each case.

Experiments and three-dimensional numerical simulations are presented to elucidate the dynamics of granular material in a cylindrical dish driven by a horizontal, periodic motion. The following phenomena are obtained both ...

The modulational instability of a linearly polarized, strong, electromagnetic wave in a (unmagnetized) positron-electron plasma is analyzed using relativistic two-fluid hydrodynamics to properly account for physical regimes ...

The emergence of affordable communication and computer technologies has brought virtual and physical space closer together in recent years. Cyber-physical systems, which are the outcome of this confluence, have changed ...
