Cellular vehicle-to-everything (C-V2X) communication facilitates the improved safety, comfort, and efficiency of vehicles and mobility by exchanging information between vehicles and other entities.In general, only the macrocell or only the femtocell is the communication infrastructure for C-V2X.Currently, a macro-femtocell network is used as the ne
We investigated how forest structure affects the occurrence and abundance of three owl species: the crested owl Lophostrix cristata Daudin, 1800, the Amazon pygmy owl Glaucidium hardyi Vielliard, 1990, and the tawny-bellied screech owl Megascops watsonii Cassin, 1849.We surveyed the owls mostly between 07:00 and 11:00 pm from July 2001 to April 200
Silicon-based light emitting diodes (LED) are indispensable elements for superdry baseball top the rapidly growing field of silicon compatible photonic integration platforms.In the present study, graphene has been utilized as an interfacial layer to realize a unique illumination mechanism for the silicon-based LEDs.We designed a Si/thick dielectric
