Abstract—Largecollectionsofelectronicpatientrecordsprovide abundantbutunder-exploredinformationonthereal-worlduseof medicines. Although they are maintained for patient administration, they provide a broad range of clinical information for data analysis. One growing interest is drug safety signal detection from these longitudinal observational data. In this paper, we proposed two novel algorit…
Abstract. The microstructural properties of Au/a-Mn2O3 catalysts moderately pretreated under different atmospheres, i.e., O2, He and H2, in relation to their activities and stabilities on CO oxidation were investigated. The highest initial activity was obtained for the He-pretreated catalyst, which, however, suffered the most severe deactivation with time on stream. Pretreatment with O2 res…
Abstract. Dehydrogenation of propane to propylene in the presence or absence of carbon dioxide was performed over a series of mixed GaxAl10−xO15 oxides (with x varying from 0 to 10) synthesized through an alcoholic coprecipitation pathway. Among the various compositions of GaxAl10−xO15, the maximum activity was observed for x = 8. Whereas the same tendency was observed for the specific …
Abstract. A series of gold catalysts deposited on various single-phase manganese oxides (MnOx, including MnO2, Mn2O3 and Mn3O4) were studied in relation to their performance in the low-temperature oxidation of CO. Gold was deposited onto the MnOx support by deposition–precipitation with urea (DP urea). The activity of the Au/MnOx catalysts for CO oxidation strongly depends on the nature o…
Abstract A new type of mesostructured ceria material was synthesized via template-assisted precipitation method and tested for the oxidative dehydrogenation (ODH) of ethylbenzene to styrene by molecular oxygen. The effect of calcination temperature on the catalytic performances of the ceria catalysts has been investigated. Among the catalysts tested, the CeO2-450 sample derived by calcinati…
