—This paper addresses the problem of energy detection of a primary signal in a cognitive radio environment over Nakagami channels. As an extension to the previous works, we start with the no diversity case, and present some alternative closed-form expressions of detection probability under Nakagami channels. Then we pay much attention to studying the(More)
The different actions of abscisic acid (ABA) in the aboveground and belowground parts of plants suggest the existence of a distinct perception mechanism between these organs. Although characterization of the soluble ABA receptors PYR1/PYL/RCAR as well as core signaling components has greatly advanced our understanding of ABA perception, signal transduction,(More)
Pyrabactin, an agonist of abscisic acid (ABA), has led to the isolation and characterization of pyrabactin resistance 1/pyrabactin resistance 1-like (PYR1/PYLs) ABA receptors in Arabidopsis, which has well explained ABA-mediated stomatal movement and stress-related gene expression. In addition to inducing stomatal closure and inhibiting transpiration, ABA(More)
AIM This study aimed to identify CD4+ T-cell-derived microparticles (MPs) and investigate their roles in rheumatoid arthritis (RA). METHODS Synovial fluids from 34 RA, 33 osteoarthritis patients and 42 healthy individuals were analyzed by flow cytometry. Human fibroblast-like synoviocytes and peripheral blood mononuclear cells were cultured with or(More)
Biomaterials for cell culture allowing simple and quantitative presentation of instructive cues enable rationalization of the interplay between cells and their surrounding microenvironment. Poly(acrylamide) (PAAm) hydrogels are popular 2D-model substrates for this purpose. However, quantitative and reproducible biofunctionalization of PAAm hydrogels with(More)
From the different functions ABA exerted between the aboveground and belowground, seed and vegetative tissues, primary root and lateral root, stimulating stomatal closure and inhibiting stomatal opening, between young and senescence leaves in stomatal movement, among different cells in plasma membrane water permeability, we addressed the organ-, tissue-,(More)
This paper addresses the problem of the optimal fusion rule adopted in cooperative spectrum sensing over different channels. Evidence from the previous literatures suggests that OR rule is a good choice for cooperative spectrum sensing. After deeply research, we find the fact is not such. Extensive analysis and numerical simulations confirm that OR rule is(More)
—Spectrum sensing is a key enabling functionality in a cognitive radio (CR) network. The fusion problem of cooperative spectrum sensing, for a cognitive radio network equipped with multi-antennas at its base-station, is considered in this paper. The base-station equipped with multi-antennas act as a fusion center which can attain not only the soft(More)
