There is a convincing experimental evidence that neutrinos are massive. Therefore we investigate the influence of the neutrino masses on the unification of gauge and Yukawa couplings in the framework of the Minimal Supersymmetric Standard Model. We estimate the contribution of the neutrino Yukawa coupling to the gauge and Yukawa coupling unification. We find that in the case of the gauge coupli...

BACKGROUND Mitral and aortic valves are known to be coupled via fibrous tissue connecting the two annuli. Previous studies evaluating this coupling have been limited to experimental animals using invasive techniques. The new matrix array transesophageal transducer provides high-resolution real-time 3D images of both valves simultaneously. We sought to develop and test a technique for quantitati...

The cracks formed by the breaking and collapse of overlying strata are oxygen supply channels for continuous combustion coal fires. development is great significance determining scope fire area controlling efficiently accurately. To study law cracks, a model in shallow seam established on basis beam theory considering coupling effect gravity load temperature field. physical based similarity pri...

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...

density functional theory (dft) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1h)–one (mpo), as a representative of pyridinone derivatives, at the fullerene (c60) surfaces. optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (cq) have been evaluated to investigate the str...
