background: we sought to compare the effectiveness and safety of sublingual versus vaginal misoprostol for the termination of pregnancy with a live full-term fetus. methods: this randomized, triple-blind, placebo-controlled clinical trial was performed on 200 primiparous women with normal, singleton, full-term pregnancies candidated for the induction of labor. sublingual and vaginal tablets con...

the semi-classical model of atom-field interaction has been fully studied for some multilevel atoms, e.g. vee, l, cascade x , y, and inverted y and so on. this issue is developed into the full-quantum electrodynamics formalism, where the probe and coupling electromagnetic fields are quantized. in this article, we investigate the full-quantum model of absorption and dispersion spectrum of trappe...

the one photon absorption (opa) cross section of a current carrying two-orbital quantum dot (qd) with strong electron-phonon interaction (polaron regime) is considered. using the self-consistent non-equilibrium hartree-fock (hf) approximation, we determine the dependence of opa cross section on the applied bias voltage, the strength of effective electron-electron interaction, and level spacing ...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

in this paper we examine the absorption and dispersion properties of a weak probe field via electromagnetically induced transparency (eit) in a four-level system. it is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. it will be shown that the controlling of absorption and dispersion spectru...
