-Rate control and power control are two important issues in cognitive radio networks. In this paper, three rate control strategies are first introduced, namely Dirty Paper Coding (DPC) strategy, Noise strategy, and Opportunistic Interference Cancellation (OIC) strategy. The achievable rates of the three strategies are also compared. Then, optimal power control algorithms are proposed, each corr...

Men typically outperform women in spatial navigation tasks, while the advantage of women in verbal fluency is more controversial. Sex differences in cognitive abilities have been related to sex-specific cognitive strategies on the one hand and sex hormone influences on the other hand. However, sex hormone and menstrual cycle influences on cognitive strategies have not been previously investigat...

This paper investigates the relationships between language learning strategies and consecutive interpretation (CI) scores (E-C) of 120 English major students in China through a quantitative study. The analysis shows that there exist significant differences of using meta-cognitive strategy and cognitive strategy between high-score group and low-score group, sub-CI scores are positively correlate...

Reading strategies, prior knowledge and cognitive load are some variables that have been related with comprehension and learning with hypertext systems. In this study we analyze the effect of two different hypertext reading strategies – coherence and interest – and two prior knowledge levels – low and high on cognitive load, and their relation with learning. For low prior knowledge readers, dat...
