a generalization of the known results in fusion frames and $g$-frames theory to continuous fusion frames which defined by m. h. faroughi and r. ahmadi, is presented in this study. continuous resolution of the identity (cri) is introduced, a new family of cri is constructed, and a number of reconstruction formulas are obtained. also, new results are given on the duality of continuous fusion fram...
IMPORTANCE The number of urban migrants in China is 300 million and is increasing rapidly in response to government policies. Urban migrants have poor access to health care, but little is known about rates of correction of refractive error among migrant children. This is of particular significance in light of recent evidence demonstrating the educational impact of providing children with specta...
Much recent criticism of Joseph Addison's Cato (1713) regards the tragedy as determinedly resistant to its eponymous protagonist's stoic heroism. Cato, it is argued, critiques Cato.

A new method of eye-care delivery that mitigates distance barriers and improves...
purpose: to determine the prevalence of refractive errors and rate of need for spectacles in students of region one in mashhad, 2006. methods: by randomized cluster sampling, 2510 students were selected and underwent eye exami-nations including refraction (cycloplegic, manifest), visual acuity, cover test and determination of the spectacle prescription as well as best corrected visual acuity. e...
Aeroelastic load simulations on a Siemens 2.3MW wind turbine have been validated using load measurements from the turbine and wind inflow measurements from a Nacelle based Lidar. A detailed survey of industrial usage of Nacelle mounted Lidars has also been conducted to extrapolate the findings from the present study to a broader framework.. Based on this information we assess the current techno...
