This paper considers the channel capacity of 60GHz wireless communications systems over Rayleigh fading channels and Ricean fading channels. The SNR and therefore capacity varies according to the communication distance. The capacity is presented for line-of-sight (LOS) and non-line-of-sight (NLOS) channels given based on a 60GHz link budget model. Phase(More)
The aim of the present study was to investigate whether asiatic acid (AA), a pentacyclic triterpene derived from Centella asiatica, exerts anti-proliferative effects on multiple myeloma RPMI 8226 cells and to determine the molecular mechanism underlying the anticancer action of AA. The study sought to analyze the potential role of AA on the proliferation of(More)
Soil contamination with arsenic (As) can cause phytotoxicity and elevated As accumulation in rice grain. Here, we used a forward genetics approach to investigate the mechanism of arsenate (As(V)) tolerance and accumulation in rice. A rice mutant hypersensitive to As(V), but not to As(III), was isolated. Genomic resequencing and complementation tests were(More)
We sought to elucidate the effects of different concentrations of dietary selenium on calcium ion release, MLCK levels, and muscle contraction in the uterine smooth muscle of rats. The selenium (Se) content of blood and of uterine smooth muscle tissues was detected by fluorescence spectrophotometry. Ca2+ content was measured by atomic absorption(More)
MiR-122 is one of the non-coding RNAs which showed its effects on the lipo-metablism, virus infection and HCC forming through regulation of liver gene expression. Its eukaryotic expression vector was constructed by using pSuper which was widely applied in the siRNA expression. The precursor of human miR-122 gene was amplified by polymerase chain reaction(More)
Lung cancer is the leading cancer and has the highest death rate. The epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) erlotinib has had a promising response in lung cancer therapy. Unfortunately, individuals with TKI-resistant EGFR mutations often develop acquired resistance against erlotinib. To overcome this resistance, in the(More)
The purpose of this study was to examine perceptions of fairness of a computer-administered quiz as a function of the anthropomorphic features of the help agent offered within the quiz environment. The addition of simple anthropomorphic cues to a computer help agent reduced the perceived friendliness of the agent, perceived intelligence of the agent, and(More)
Joseph Paul Cohen, Henry Z. Lo, Tingting Lu, and Wei Ding at the University of Massachusetts Boston ({joecohen, henryzlo, ding}@cs.umb.edu, lutingting@buaa.edu.cn) Introduction Craters are among the most studied geomorphic features in the Solar System because they yield important information about the past and present geological processes and provide(More)
Mycoplasma bovis infection can cause endometrial inflammation leading to infertility and involuntary culling in dairy cows. Because extracellular matrix (ECM) proteins affect the adherence of mycoplasma to eukaryotic cell surface, they may play a role in the pathogenesis of the bacteria. The objective of the present study was to evaluate the endometrial(More)
