A further development of the synchronous array method (SAM) as a medium access control scheme for large-scale ad hoc wireless networks is presented. Under SAM, all transmissions of data packets between adjacent nodes are synchronized on a frame-byframe basis, and the spacing between concurrent cochannel transmissions of data packets is properly controlled. An opportunistic SAM (O-SAM) is presen...

Hydroxyapatite formation was examined at the surface of self-assembled monolayers (SAMs) modified with four functional groups, -COOH, -NH(2), -CH(3), and -OH. For COOH-SAM and NH(2)-SAM, scanning electron spectroscopic observation showed that flake-like sheet crystals covered the whole wafer and small broccoli-like crystals were observed occasionally on the flake-like crystal base layer. For CH...

Metabolism of levodopa via the enzyme catechol-O-methyltransferase requires S-adenosylmethionine (SAM) as a methyl donor. SAM caused Parkinson disease (PD)-like symptoms in rodents. Therefore, SAM could contribute to a decreased efficacy of levodopa in the long term. SAM levels were significantly reduced in levodopa-treated PD patients, but they showed increased enzyme methionine adenosyl trans...

This paper proposes a novel hyperspectral matching algorithm by integrating the stochastic Jeffries-Matusita measure (JM) and the deterministic Spectral Angle Mapper (SAM), to accurately map the species and the associated landcover types of the mangroves of east coast of India using hyperspectral satellite images. The JM-SAM algorithm signifies the combination of a qualitative distance measure ...

objective: the aim of this study is to explore the confirmatory factor analysis results of the persian adaptation of statistics anxiety measure (sam), proposed by earp. method: the validity and reliability assessments of the scale were performed on 298 college students chosen randomly from tabriz university in iran. confirmatory factor analysis (cfa) was carried out to determine the factor stru...

Keratinocyte growth factor (KGF) from gastric fibroblasts have been reported to stimulate proliferation of scirrhous gastric cancer cells with K-samII amplification in a paracrine manner. The aim of this study was to evaluate the clinical significance of the co-expression of K-sam and KGF in gastric carcinomas. A total of 136 primary gastric tumors were investigated by staining with antibodies ...
