Effects of neighboring transitions on the mechanisms of electromagnetically induced absorption and transparency in an open degenerate multilevel system

open access: yesScientific Reports, 2022
In this study, optical Bloch equations with and without neighboring hyperfine states near the degenerate two-level system (DTLS) in the challenging case of $$^{85}$$ 85 Rb D2 transition, which involves the Doppler broadening effect, are solved.

Review of ionospheric irregularities and ionospheric electrodynamic coupling in the middle latitude region

open access: yesEarth and Planetary Physics, 2021
This paper briefly reviews ionospheric irregularities that occur in the E and F regions at mid-latitudes. Sporadic E (ES) is a common ionospheric irregularity phenomenon that is first noticed in the E layer.

Impairment of Excitation-Contraction Coupling in Right Ventricular Hypertrophied Muscle with Fibrosis Induced by Pulmonary Artery Banding. [PDF]

open access: yesPLoS ONE, 2017
Interstitial myocardial fibrosis is one of the factors responsible for dysfunction of the heart. However, how interstitial fibrosis affects cardiac function and excitation-contraction coupling (E-C coupling) has not yet been clarified.

Induced CP-violation in the Euler–Heisenberg Lagrangian

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
In this paper, we examine the behaviour of the Euler–Heisenberg effective action in the presence of a novel axial coupling among the gauge field and the fermionic matter.

Night-time F-region and daytime E-region ionospheric drifts measured at Udaipur during solar flares [PDF]

open access: yesAnnales Geophysicae, 2002
Ionospheric drifts measured at a low latitude station, Udaipur (Geomag. Lat. 14.5° N), in the night-time F-region and daytime E-region during solar flares have been studied. The night-time observations, which correspond to the F-region drifts, were
