BACKGROUND The cost efficient two-stage design is often used in genome-wide association studies (GWASs) in searching for genetic loci underlying the susceptibility for complex diseases. Replication-based analysis, which considers data from each stage separately, often suffers from loss of efficiency. Joint test that combines data from both stages has been(More)
In cognitive radio networks (CRNs), channel availability is one of the key factors in constructing policies for sensing order selection. It provides information about the channel occupancy and enables second user to find the available channel efficiently. In this paper we investigate the channel availability in a CRN system with correlated channels, by(More)
We consider the problem of the selection of channel sensing order in cognitive radio networks (CRNs) where the primary users (PUs) use multiple channels for data transmission. We assume that the occupancy state of each channel is correlated with that of the other channels, and the spectrum occupancy state for all the channels follows the discrete-time(More)
OBJECTIVE To explore the correlation between expression of mitogen-activated protein kinase kinase 4 (MKK4) and metastasis of oral squamous cell carcinoma (OSCC). METHODS Expression levels of MKK4 mRNA and protein were examined in surgically resected oral squamous cell carcinoma specimens and corresponding lymph nodes by semi-quantitative reverse(More)
In the cognitive radio networks (CRNs), the reliability, the efficiency and the fairness of the spectrum allocation is highly related to the quality of service (QoS) performance for the users. But in the overlay CRNs the QoS performance for the SUs is difficult to obtain due to the inherent opportunistic property of the spectrum resources for the SU's data(More)
