In this paper, we present an interference model for cognitive radio (CR) networks employing power control, contention control or hybrid power/contention control schemes. For the first case, a power control scheme is proposed to govern the transmission power of a CR node. For the second one, a contention control scheme at the media access control (MAC)(More)
Transgenic plants have become attractive as bioreactors to produce heterologous proteins that can be developed as edible vaccines. In the present study, transgenic rice expressing the envelope protein (E) of Japanese encephalitis virus (JEV), under the control of a dual cauliflower mosaic virus (CaMV 35S) promoter, was generated by Agrobacterium-mediated(More)
The RNA-binding glycine-rich protein (RB-GRP) family is characterized by the presence of a glycine-rich domain arranged in (Gly)n-X repeats and an RNA-recognition motif (RRM). RB-GRPs participate in varied physiological and biochemical processes especially in the stress response of plants. In this study, a total of 23 RB-GRPs distributed on 10 chromosomes(More)
The co-transcribed orf355-orf77 region of the mitochondrial genome is associated with S cytoplasmic male sterility (CMS-S) in maize; the amounts of its 1.6- and 2.8-kb transcripts were previously shown to be greatly reduced in fertility-restored microspores relative to the amounts in sterile plants. To investigate the mechanism underlying this reduction,(More)
New partial relay selection schemes for cooperative diversity based on amplify-and-forward (AF) relaying are proposed in Nakagami-m fading channels. Their performances are compared with the conventional partial selection scheme. Numerical results show that the new schemes have performance gains of up to 5 dB over the conventional scheme. In some cases,(More)
The algorithms of weighted association rules mining and weights confirming were studied in alarm correlation analysis. A novel method named Neural Network based WFP-Tree (NNWFP) for mining association rules was proposed. NNWFP differs from the classical weighted association rules mining algorithm MINWAL (O). It is an efficient algorithm based on weighted(More)
In this paper, we propose a game-theoretic power control algorithm to minimize the total power consumption in a cooperative communication network that transmits information from multiple sources to a destination via multiple relays to save energy and improve communication performance. Under the amplify-and-forward relaying scheme, the proposed approach not(More)
With the flourishing of wireless information access, indoor positioning is becoming a topic of interest in both academic and industry community. Numerous techniques have been proposed to address this problem under diverse circumstances. Recently, the area of indoor positioning is dominated by three kinds of methodologies, such as range-based positioning,(More)
