A trust management mechanism based on the jury system for distributed cognitive radio networks is proposed in this paper. The "jury user" is designed to collaboratively examine the reputation of the cognitive user in the networks and to perform data fusion and spectrum allocation for distributed cognitive radio networks. Simulation analysis results show that the proposed scheme can ensure accuracy and fairness in trust evaluation and improve effectiveness and flexibility of spectrum allocation.展开更多

However, few studies have examined such effects of EPO in the clinic. In this study we enrolled patients with spinal cord ischemia-reperfusion （I-R） injury to investigate the clinical application of EPO and methylprednisolone （MP） for the neuroprotection against spinal cord I-R injury. Retrospective analysis of 63 cases of spinal cord I-R injury was performed. The Frankel neurological performance scale was used to evaluate the neurological function after spinal cord injury （SCI）, including 12 cases of scale B, 30 cases of scale C, and 21 cases of scale D. These cases were divided into 2 groups： group A （27 cases） got treatment with both EPO and MP; group B （36 cases） got treatment with MP only. The neurological function of patients after treatment was evaluated by American Spinal Cord Injury Association （ASIA） index score, and activity of daily living （ADL） of the patients was also recorded. All patients got follow-up and the follow-up period ranged from 24 to 39 months （mean 26 months）. There was no significance difference in neurological function between groups A and B before the treatment （P〉0.05）. However, the neurological function and ADL scores were significantly improved 1 week, 1 year or 2 years after the treatment compared to those before the treatment （P〈0.05）, and the improvement was more significant in group A than in group B （P〈0.05）. It is suggested that the clinical application of EPO and MP provides the neuroprotection against spinal cord I-R injury.展开更多

At present, the English term “jury” is generally translated as “陪审团” and “陪审” in Chinese. The Chinese translations “陪审团” and “陪审” fail to accurately translate the essential features of this system, and the true implications of the term and are, on the contrary, quite misleading. There are two types of juries： the jury determining criminal guilt or innocence and the jury deciding whether someone should be accused. Both types of juries play leading roles in the democratic legal system and legal procedure. Neither type of jury has anything to do with “陪” or “审”, therefore, the translation “陪审” is totally erroneous. Re-translation of the term ＂jury＂ is necessary. In accordance with its true implications and functions, “jury” can be translated as “决认团” and “决认”. The word stem of the Chinese translations of the term group in the jury system should be “决认”. By analogy, such terms as （a） “jury system”, （b） “juror/juryperson/juryman”, （c） “jurywoman”, （d） “jury duty” and （e） “jury box” should be translated respectively as （a）“决认制度”, （b）“决认员”, （c）“女决认员”, （d）“决认责任” and （e）“决认席”. The Chinese translation “决认” is fully justified to replace “陪审”.展开更多

The author gives an affirmative answer that the jury system should be established as soon as possible in our country in order to give full play to the efficacy and value of judicial democracy and supervision. This paper tries to analyze from the following three aspects. Firstly, it analyzes the differences and advantages and disadvantages of two jury patterns including the jury system and the mixed court system; then,based on the statement of development and existing problems of the mixed court system in our country,it analyzes the feasibility of application of the jury system in our country combining with national conditions; finally, social effect of the introduction of the jury system is evaluated,which affects the situation as a whole domino.展开更多

文摘In the trust management scheme of the distributed cognitive radio networks, the absence of the central control devices cause many problems such as a lack of standardized control for trust computation, and the absence of the decision makers in trust evaluation and collaborative decision making.

The "jury user" is designed to collaboratively examine the reputation of the cognitive user in the networks and to perform data fusion and spectrum allocation for distributed cognitive radio networks. Simulation analysis results show that the proposed scheme can ensure accuracy and fairness in trust evaluation and improve effectiveness and flexibility of spectrum allocation.
