Image-Based Localization (IBL) is the problem of estimating the 3D pose of a camera with respect to a 3D representation of the scene. IBL is quite challenging in largescale environments spanning a wide variety of viewpoints, illumination, and areas where matching a query image against hundreds of thousands of 3D points becomes prone to a large number of outliers and ambiguous situations. The cu...

to produce embryogenic callus and somatic embryos, tendril explants were collected and cultured in ms medium supplemented with various concentrations of hormones. after one month most of explants produced callus. the highest percent of embryogenic callus obtained in ms medium supplemented with 4.5 µm bap and 1µm 2,4-d. production of somatic embryos was depended on genotype and medium. yaghouti ...

clarithromycin (clm) is a member of macrolide family with broad spectrum antibiotic activity. it is practically insoluble in water and its poor solubility is ph dependent. in this study, series of nanosuspensions containing clm and stabilizer such as hpmc, nacmc, polysorbate 80, poloxamer 188 and polyvinyl alcohol in various ratios were prepared using sonoprecipitation method. briefly, clm was ...
