Drug and Nondrug Alternatives to Altering Mood

This study examined the usage patterns of nondrug alternatives and obtained knowledge that will be beneficial to future drug abuse prevention and rehabilitation in college students. The purpose was to identify the specific nondrug/drug alternatives used to alter mood by non-Hispanic Whites and Hispanics. Analysis revealed that engaging in discussion with spouse/friends was used most frequently to alter mood. The overall distribution of drug alternatives and nondrug alternatives differed significantly from chance in 72 participants. Further pair-wise analyses found there were significant differences between five drug and nondrug alternatives endorsed by non-Hispanic Whites and Hispanics. In conclusion, it was found that Non-Hispanic Whites engage in discussion with spouse/friend to alter mood more frequently than Hispanics. Hispanics engaged in personal contemplation more frequently than non-Hispanic Whites due to their cultural background

Energy harvesting over Rician fading channel: A performance analysis for half-duplex bidirectional sensor networks under hardware impairments

In this paper, a rigorous analysis of the performance of time-switching energy harvesting strategy that is applied for a half-duplex bidirectional wireless sensor network with intermediate relay over a Rician fading channel is presented to provide the exact-form expressions of the outage probability, achievable throughput and the symbol-error-rate (SER) of the system under the hardware impairment condition. Using the proposed probabilistic models for wireless channels between mobile nodes as well as for the hardware noises, we derive the outage probability of the system, and then the throughput and SER can be obtained as a result. Both exact analysis and asymptotic analysis at high signal-power-to-noise-ratio regime are provided. Monte Carlo simulation is also conducted to verify the analysis. This work confirms the effectiveness of energy harvesting applied in wireless sensor networks over a Rician fading channel, and can provide an insightful understanding about the effect of various parameters on the system performance.Web of Science186art. no. 1781
