Sensor networks are widely used in many applications to collaboratively collect information from the physical environment. In these applications, the exploration of the relationship and linkage of sensing data within multiple regions can be naturally expressed by joining tuples in these regions. However, the highly distributed and resource-constraint nature(More)
This paper presents a hybrid interconnection network architecture to support integrated communication services for multicomputer-based database and multimedia systems. Our study shows that existing wormhole routing networks are inefficient in transfer of long files. We demonstrate the feasibility of integrating different network techniques based on virtual(More)
The cyclostationarity feature of modulated signals was widely applied for signal detection and parameter estimation. Previous studies on blind recognition of the modulation type of a received signal are generally performed in a single domain. This paper presents a new recognition approach through establishing a joint delay-cyclic frequency feature decision(More)
Tumor necrosis factor (TNF) is a pleiotropic and potent inflammatory cytokine produced during inflammation. In this study, we cloned the tumor necrosis factor-α (TNFα) complementary DNA (cDNA) gene from common carp Cyprinus carpio. The TNFα4 cDNA was 1318 bp in length and contained a 768-bp open reading frame, which putatively encoded 255 amino acids. The(More)
BACKGROUND The morphological identification of different Hippophae species (Shaji) was difficult. This study aims to discriminate between medicinal and non-medicinal Hippophae species by DNA barcodes, the ITS2, psbA-trnH, and a combination of ITS2 and psbA-trnH (ITS2 + psbA-trnH). METHODS DNA was extracted from the dried fruit samples. Primer pairs(More)
Soil samples taken from Xilamuren Grassland, Resonant Sand Bay, Inner Mongolia, and Yichang, western Hubei Province were investigated by Mössbauer spectroscopy at room temperature and 20 K. This was supplemented with phase identification and elemental analysis to obtain information about the composition and structure types of Fe-containing compounds. The(More)
