Enhanced Lee model from rough terrain sampling data aspect
No full textThe Lee propagation prediction model has been well recognized by the wireless industry as one of the most accurate propagation prediction models. This paper discusses innovative approaches dealing with rough digital samples of terrain data and enhancements to the Lee model during the validation process. In general, the Lee model is composed of two parts, the impact of man-made structures and the impact of the natural terrain variation [1-6]. There are other papers discuss innovative algorithms on calculating effective antenna gain [7,8] and diffraction loss [7-9] as well as on enhancing the Lee model [12-14]. This paper focuses on the natural (terrain) factor. The new algorithm presented in this paper is quite different than others as it integrates both Line Of Site (LOS) and shadow loss calculation together for the Lee model. First, in the LOS scenario, it addresses the issue of big swing of effective antenna gain due to non-continuous terrain data. Second, in the non-LOS situation, the effective antenna gain is integrated with shadow loss. Both single knife edge and multiple knife edge scenarios are discussed. The new algorithm is developed based on the analysis of measured and predicted (the theoretical shadow loss and effective antenna gain) data. The new algorithm involves more calculation but it improves the accuracy of the predicted value. This algorithm was implemented and verified using field terrain and measurement data from a variety of different environments and different countries including Italy, US, Spain, Japan, South Korea, Taiwan and Romania. ?2010 IEEE.EI

Stomatal opening by fusicoccin is accompanied by depolymerization of actin filaments in guard cells
No full textActin in guard cells is assembled in a radial pattern when stomata are induced to open under light, but the filaments are disassembled when stomata are closed under darkness or by abscisic acid (S.-O. Fun and Y. Lee, 1997, Plant Physiol. 115: 1491-1498). To test if signals that open stomata commonly generate the polymerized form of actin in guard cells, leaves of Commelina communis L. were treated with a potent stomatal opening agent, fusicoccin, and the actin organization examined by immunolocalization techniques. When stomata were induced to open by fusicoccin, hardly any of the filamentous form of actin was detected. instead, the actin resembled that present in guard cells that had been treated with an antagonist to actin filaments. cytochalasin D, and showed a sharp contrast to the long filaments developed in illuminated guard cells. Furthermore, treatment of illuminated leaves with fusicoccin disintegrated actin filaments that had already been formed in the guard cells. Preincubation of leaves with phalloidin, which interferes with fusicoccin-induced actin depolymerization, delayed fusicoccin-induced opening during the early phase. These observations suggest that the prevention of actin filament formation and/or depolymerization of actin filaments may accelerate the stomatal opening process in response to fusicoccin.X1125sciescopu
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
Full text linkBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
