An effective approach to improve the detection efficiency of nanoscale light sources relies on a planar antenna configuration, which beams emitted into narrow cone. Planar antennas operate like optical Yagi-Uda antennas, where reflector and director elements are made metal films. Here we introduce investigate, both theoretically experimentally, scanning implementation antenna. Using small ensem...

japanese plum (prunus salicina lindl.) having originated from china, is now one of the important fruit trees in many countries in the world. knowledge of genetic diversity among existing germplasms provides the possibility of parental selection in breeding improvement programs. for assessment of genetic diversity and relationship among genotypes in iran (ramsar, velyan karaj and mashhad) and fo...

METHODS The effect of glucose, cellobiose and xylose on the regulation of cellulolytic activity in Cellulomonas sp. ZZbc was investigated. The addition of 1% glucose, cellobiose or xylose to actively growing bagasse pith cultures repressed the cellulose system. No enzyme inactivation by sugar concentrations up to 1.5% was detected. Both cellobiose and xylose, at concentrations ranging from 0.00...

The United States Geological Survey has been researching generalization approaches to enable multiple-scale display and delivery of geographic data. This paper presents automated methods to prune network and polygon features of the United States high-resolution National Hydrography Dataset (NHD) to lower resolutions. Feature-pruning rules, data enrichment, and partitioning are derived from know...
