Nitrification is believed to be one of the major sources of N2O production emitted from soil. Previous studies showed that both ammonia-oxidising bacteria (AOB) and archaea (AOA) can produce N2O via nitrification but their relative contributions are still poorly defined. Here, we used acetylene, an inhibitor of AOB and AOA ammonia monooxygenase (AMO), and(More)
Solid tumors frequently metastasize to bone. Two bisphosphonates have been investigated for bone metastases including pamidronate disodium and zoledronic acid.By searching the PubMed, Embase, Wanfang, and China National Knowledge Infrastructure (CNKI) databases, we conducted a meta-analysis to determine the efficacy and safety of zoledronic acid compared(More)
With the rapid development of information society, intricate relationship between objects establish huge heterogeneous networks. The linkage is affected by multiple factors, which makes community detection on heterogeneous network a difficult task. Traditional clustering algorithms focus on divided factors, ignoring the combination of them. If the structure(More)
A new slotted split-channel medium access control (SSC-MAC) protocol is proposed for multihop wireless networks to maximize concurrent packet transmissions. By adjusting the relationship between the reservation slot (RS) on the control channel (CCH), data packet transmission slot (TS) on the data channel (DCH) and acknowledgment slot (AS) on the(More)
