A driven optical cavity containing a nonlinear medium can support stable, soliton-like objects, bright non-diffracting spots of light on a uniform background. Importantly, the nonlinear medium need not support ordinary (propagating) spatial solitons, and cavity solitons have been both predicted and observed in a saturable absorber, and predicted to even exist in self-defocusing media. The histo...

introduction: this study was designed to evaluate the usefulness of mastoid cavity obliteration with combined bone pâté and palva flap in the prevention of problematic mastoid cavities after canal wall down mastoidectomy.   materials and methods: in a prospective longitudinal study with a mean follow-up of 28 months conducted between 2008–2012, a series of 56 ears in 48 patients with chronic ot...

introduction: in a prospective blind study, we evaluated sonohysterography (shg) as a diagnostic tool for uterine cavity and tubal patency and compare shg with laparoscopy in tubal patency and hysterosalpyngography for uterine anomaly as gold standard methods. material and methods: 76 infertile patients undergone shg and hsg and laparoscopy and comparison between the different diagnostic techni...

Propane combustion in a trapped vortex combustor (TVC) is characterized via large eddy simulation coupled with filtered mass density function. A computational algorithm based on high order finite difference (FD) schemes, is employed to solve the Eulerian filtered compressible Navier-Stokes equations. In contrast, a Lagrangian Monte-Carlo solver based on the filtered mass density function is inv...

A dielectric body couples with electromagnetic fields through radiation pressure and electrostrictive forces, which mediate phonon-photon coupling in cavity optomechanics. In a magnetic medium, according to the Korteweg-Helmholtz formula, which describes the electromagnetic force density acting on a medium, magneostrictive forces should arise and lead to phonon-magnon interaction. We report suc...
