Abstract Aiming at the engineering problem that 5G base station antenna is difficult to locate efficiently in complex electromagnetic Gift Card environment, a two-stage positioning method of 5G base station antenna substation is proposed, which considers signal path loss and antenna RF radiation.Firstly, the path loss solution model of the 5G base
The protozoan Plug disease is a major global health concern.Amoebiasis, leishmaniasis, Chagas disease, and African sleeping sickness affect several million people worldwide, leading to millions of deaths annually and immense social and economic problems.Iron is an essential nutrient for nearly all microbes, including invading pathogens.The majority
We study a heretofore unexamined type of product differentiation, horizontally differentiated products with differential costs, and apply the analysis Baby copyright to retail pricing of fluid milk products.The theoretical models yield unique predictions for the relationship among prices of the four horizontally differentiated fluid milk products (
Early drought stress detection is crucial for restoring productivity, ensuring recovery, and providing vital information for mortality prevention.Hyperspectral remote sensing which is sensitive to subtle changes in leaf constituents and canopy structure is widely used to study how drought stress manifests and evolves over time.Drought impacts are c
