Past two decades have shown the unprecedentedly rapid emergence of dye-sensitized solar cells (DSSCs) that are efficient, inexpensive, and eco-friendly.However, structural studies of the internal solar cells have not made much progress because of the high cost and complexity of the fabrication.In this study, therefore, we designed and fabricated a
Joint Notebook Cover downlink spectrum resource block(SRB) and power allocation was studied based on OFDMA n cog-nitive small cell networks.In a distributed framework, small cell base stations (SCBS) could share free spectrum re-sources with open access to maximize their energy efficiency (EE) respectively.The competition among SCBS made the dynami
Abstract Background Easter Basket Tags Commonly known as sun-coral, Tubastraea tagusensis is an azooxanthellate scleractinian coral that successfully invaded the Southwestern Atlantic causing significant seascape changes.Today it is reported to over 3500 km along the Brazilian coast, with several rocky shores displaying high substrate coverage.Ap
