Box 1700, STN CSC, Victoria, B.C., Canada V8W 2Y2; e-mail: [email protected]; Phone: (250) 721-8540; FAX: (250) 721-6214 Abstract We show that the full asymptotic null distribution for Watson’s 2 N U statistic, modified for discrete data, can be computed simply and exactly by standard methods. Previous approximate qua...
Background: Internet has played an increasingly important role in people’s lives; however, there is a global concern that it may cause negative effects on health. The purpose of this study was to assess the prevalence of Internet addiction (IA), and its relationship with general health status among high school students. Materials and Methods: </s...

721 Abstract— Polymer base organic PN junction with various ion types was studied. Low-energy ion implantation technique(~keV) is very useful in physical doping on PPP(Polyparaphenylene) polymer. By double implantation, effective organic PN junction was achieved. The best obtained electrical I-V property was rectification ratio which was about 10000. However, still have problems in low junction...
