In nature and engineering world, the acquired signals are usually affected by multiple complicated factors appear as multicomponent nonstationary modes. such many other situations, it is necessary to separate these into a finite number of monocomponents represent intrinsic modes underlying dynamics implicated in source signals. this paper, we consider mode retrieval signal which has crossing in...

nasopharyngeal angiofibroma is a relatively uncommon vascular tumor affecting adolescent males and it characteristically originates in the posterior lateral wall of the nasopharynx. primary extra-nasopharyngeal angiofibroma is very rare. here, i present a case of angiofibroma of the parapharyngeal space in a 53-year-old woman with ct and sonographic findings.

This article reviews synthetic approaches, properties and potential use of nano micron sized forms particles coats calcium titanate CaTiO3 its composites. Our aim is to classify these according the way their fabrication provide a brief outline methods, applications as inspired from luminescence, photocatalytic catalytic performance, pollutants removal ability, inducement biomimetic hydroxylapat...
