The quality assessment was accomplished according to the Cochrane risk of bias tool. Pair-wise meta-analyses were carried out by Rev Man 5.3. A random-effects model of NMA was used to compare the different regimens of SMICs with regard to efficacy by STATA 13.0.RESULTS: A total of 111 studies involving 10 500patients were included in the NMA. The methodological quality of included studies was not high.Current evidence shows that salvianolate(SI) is the optimal treatment for UAP in improving the total efficacy against UAP. Guanxingning(GXN) is the optimal treatment for UAP for improving the total effectiveness of electrocardiography.CONCLUSION: SMICs have advantages in preventing cardiovascular events. GXN, SI, and Danhong had the greatest probability of being the best treatment in the total efficacy against UAP and for improving the total effectiveness of electrocardiography.展开更多

A Bayesian network meta-analysis was conducted. Outcome measures: Efficacy was assessed by changes in scores of the Alzheimer's Disease Assessment Scale, cognitive subscale, Mini-Mental State Examination, Neuropsychiatric Inventory scores and Clinician's Interview-Based Impression of Change Scale Plus Caregiver's Input, Activities of Daily Living, the Clinical Dementia Rating scale. Safety was evaluated by mortality, total adverse events(TAEs), serious adverse events(SAEs), nausea, vomiting. diarrhea, or cerebrovascular accidents(CVAs). Results: After screening 1717 citations, 12 randomized controlled trials were included. Donepezil and rivastigmine(mean difference(e) = –0.77, 95% confidence interval(CI): 0.25–1.32; MD = 1.05, 95% CI: 0.18–1.79) were significantly more effective than placebo in reducing Mini-Mental State Examination scores. Donepezil, galantamine, and memantine(MD = –1.30, 95% CI: –2.27 to –0.42; MD = –1.67, 95% CI: –3.36 to –0.06; MD = –2.27, 95% CI: –3.91 to –0.53) showed superior benefits on the Alzheimer's Disease Assessment Scale–cognitive scores compared with placebo. Memantine(MD = 2.71, 95% CI: 1.05–7.29) improved global status(Clinician's Interview-Based Impression of Change Scale Plus Caregiver's Input) more than the placebo. Safety results revealed that donepezil 10 mg(odds ratio(OR) = 3.04, 95% CI: 1.86–5.41) contributed to higer risk of adverse events than placebo. Galantamine(OR = 5.64, 95% CI: 1.31–26.71) increased the risk of nausea. Rivastigmine(OR = 16.80, 95% CI: 1.78–319.26) increased the risk of vomiting. No agents displayed a significant risk of serious adverse events, mortality, cerebrovascular accidents, or diarrhea.Conclusion: We found significant efficacy of donepezil, galantamine, and memantine on cognition. Memantine can provide significant efficacy in global status. They are all safe and well tolerated.展开更多

This book chapter deals with history and foundation of cognitive radio. In recent years wireless communications have experienced an unprecedented success for the rapidity of their diffusion and for their impact in the life of human society. The technologies used in wireless communications are far from being mature and many changes induced by their progress are still to come. Cognitive radio is one of these technologies and is regarded as a key technology to increase efficiency in wireless communications. In many circumstances the spectrum assigned to wireless communications is not fully used. The main goal of cognitive radio is to improve the exploitation of the spectrum. The idea is to let the unlicensed users to access the spectrum left unused by the licensed users. In this chapter the main steps of the brief history of cognitive radio are presented including issues related to policy regulations that have influenced the technology and alternative technical solutions as software defined radio. The chapter ends with a brief discussion of future applications in wireless communications and of the challenges that they pose to cognitive radio. This is a well written and informative chapter that deals with an important technology. I suggest to read it. Chapter 6 MIMO systems and cooperative networks performances by Kosai Raoof, Maha Ben Zid. This chapter deals with MIMO (Multiple Input Multiple Output) systems. This is a technology used to in wireless communications to improve transmission robustness and to increase spectral efficiency. The relation between MIMO systems and wireless sensor networks is investigated. Spatially distributed wireless sensor networks are deployed for many different purposes, let us mention, for example, environment monitoring missions or surveillance missions. Cooperative networks with virtual MIMO channels are studied, in particular networks aware of their environment are considered. These are cognitive networks that operate in wireless form. This last feature is the bridge that links them to cognitive radio. In fact the cognitive radio technology is used to allocate spectrum to the users of the cognitive network in an adaptive way. This book chapter deals with a specific application, however, this is a very important application and this work is written in a way that makes it readable by a wide audience technically oriented readers.

Most Honeypot surveys and/or reviews focus on specific and narrow Honeypot research areas. This study aims at exploring and presenting advances and trends in Honeypot’s research and development areas. To this end, a systematic methodology and meta-review analysis were applied to the selection, evaluation, and qualitative examination of the most influential Honeypot surveys and/or reviews available in scientific bibliographic databases. A total of 188 papers have been evaluated and 22 research papers are found by this study to have a higher impact. The findings of the study suggest that the Honeypot survey and/or review papers of considerable relevance to the research community were mostly published in 2018, by IEEE, in conferences organized in India, and included in the IEEE Xplore database. Also, there have been few qualities Honeypot surveys and/or reviews published after 2018. Furthermore, the study identified 10 classes of vital and emerging themes and/or key topics in Honeypot research. This work contributes to research efforts employing established systematic review and reporting methods in Honeypot research. We have included our meta-review methodology, in order to allow further work in this area aiming at a better understanding of the progression of Honeypot research and advances.展开更多
