Three-dimensional UnderWater Acoustic Sensor Networks (UWASN) are supposed to be deployed for many applications. However, a protocol for sensors' self-localization and time-synchronization in UWASN remains a challenge problem. In this paper, we developed a multilateration algorithm which could reliably localize and synchronize underwater sensor networks by(More)
MicroRNAs (miRNAs) have been proven to play crucial roles in cancer, including tumor chemotherapy resistance and metastasis of non-small-cell lung cancer (NSCLC). TGFβ signal pathway abnormality is widely found in cancer and correlates with tumor proliferation, apoptosis and metastasis. Here, miR-17, 20a, 20b were detected down-regulated in A549/DDP cells(More)

—One of the most crucial functionalities of cognitive radio networks is spectrum sensing. Completing this task in an accurate manner requires opportunistic spectrum access. Traditionally , sensing has been performed through energy detection by each individual secondary user. In order to increase accuracy, individual measurements are aggregated using(More)
