We propose two possible eikonal operators encoding the effects of classical radiation as coherent states gravitons and show how to compute from them different observables. In first proposal, only genuinely propagating are included, while, in second, zero-frequency modes added order recover a static gravitational field. calculate radiated energy-momentum change each particle's momentum, or impul...

The elastic scattering of kaons from different targets 6Li, 12C, and 40Ca at energies 635, 715, 800 MeV have been studied. equivalent local potential form Kisslinger optical with the eikonal approximation using Wallace expansion up to 2nd order used. depends on density target nuclei, amplitude parameters. Satisfactory fits experimental data are obtained.

We present a new model of human cardiac electromechanics for the left ventricle where electrophysiology is described by Reaction–Eikonal and which enables an off-line resolution reaction model, thus entailing big saving computational time. Subcellular dynamics coupled with tissue mechanics, in turn Windkessel blood circulation. Our numerical results show that proposed able to provide physiologi...
