We observe fine structure in the resonance spectra of optical microcavities. identify polarization-resolved modes spectrum and find that frequencies split accordance with theoretical prediction. The observed is dominantly caused by an spin-orbit coupling non-paraxial propagation reflection. Both effects are intrinsic, i.e. present ideal rotation-symmetric system, scale inversely proportional to...

Cosmography is a phenomenological and relatively model-independent approach to cosmology, where physical quantities are expanded as Taylor series in the cosmological redshift, or related variables. Here we apply this methodology constrain possible variations of fine-structure constant, α. Two peculiarities case existence high-redshift data, fact that one term directly tightly constraint by loca...

Most popular models of narratives and narrative analyses have been drawn on native stories, yet EFL learners’ narratives have not received due narrative analysis. The present study then aims at scrutinizing the structure of personal English stories as told by EFL learners. To this aim, three hundred narratives were collected through classroom discussions and interviews. Qualitative analysis met...
