In this work, we reassess two known processes of Quantum Electrodynamics involving electrons and muons. The photon propagator is modified by a CPT-even Lorentz-violating (LV) tensor, while fermion lines and the vertex interaction are not altered. Usi

Physical Review
In this paper, we investigate an electrodynamics in which the physical modes are coupled to a Lorentz-violating (LV) background by means of a higher-derivative term. We analyze the modes associated with the dispersion relations (DRs) obtained from th

The CPT-even gauge sector of the Standard Model Extension is composed of nineteen components comprised in the tensor $(K_{F})_{\mu \nu\rho\sigma}$, of \ which nine do not yield birefringence. In this work, we examine the Maxwell electrodynamics suppl

Background: In patients (pts) with chest pain and acute coronary syndromes, troponins provide diagnostic sensitivity and prognostic information, but there is a 6 hour lag between symptoms and elevation. An earlier marker of necrosis is myoglobin, but

Background: Rest myocardial perfusion imaging (RMPI) in the evaluation of patients with chest pain has been shown to provide diagnostic information, but may also provide prognostic data. The aim of this study was to find the relationship between RMPI
