一种应用于多媒体通信的实时调度算法

随着网络技术和计算技术的发展,多媒体通信作为一种重要的应用领域,获得了越来越多的应用,而其中重要的一个研究主题就是实时调度的效率。传统的实时调度算法有着良好的理论模型,但是由于忽略了许多系统开销,其性能有待提高。该文针对多媒体通信的周期性和实时性提出了一种延迟抢占的策略,与传统立即抢占的模型相比,取得了更好的实际效果,提高了CPU的利用率。

在以移动互联网技术为支撑的传播环境下,媒介融合不断升级,以全媒体整合性布局、全产业链衍生为传播价值起点的新型游戏传播范式,正在全面取代传统的游戏传播范式。在此转型过程中,游戏传播价值链中的核心IP、文化圈层与媒介生态成为关键点。手机游戏《阴阳师》即以小说IP为基础,以二次元文化为传播圈层,通过互动性极强的游戏形式营造出持续发展的文化传播媒介生态。     

后WTO时代的中国知识产权保护：成就、差距与对策

入世已十年,中国的知识产权保护在立法、执法和司法领域已经取得巨大的成就,但与TRIPS相比,还存在着诸多差距。为了更有效地解决这些问题,首先必须认清国情并意识到保护的必要性,在制度层面上缩小与TRIPS的差距,通过科学立法来不断完善我国的知识产权法律体系;在执法层面上提高行政执法的质和量来确保知识产权法的实施;逐步完善司法保护机制,进一步提高知识产权的司法保护水平。     

A dynamic power prior for borrowing historical data in noninferiority trials with binary endpoint

Traditionally, noninferiority hypotheses have been tested using a frequentist method with a fixed margin. Given that information for the control group is often available from previous studies, it is interesting to consider a Bayesian approach in which information is “borrowed” for the control group to improve efficiency. However, construction of an appropriate informative prior can be challenging. In this paper, we consider a hybrid Bayesian approach for testing noninferiority hypotheses in studies with a binary endpoint. To account for heterogeneity between the historical information and the current trial for the control group, a dynamic P value–based power prior parameter is proposed to adjust the amount of information borrowed from the historical data. This approach extends the simple test‐then‐pool method to allow a continuous discounting power parameter. An adjusted α level is also proposed to better control the type I error. Simulations are conducted to investigate the performance of the proposed method and to make comparisons with other methods including test‐then‐pool and hierarchical modeling. The methods are illustrated with data from vaccine clinical trials.

Defining and Measuring the Institutional Context of National Intellectual Property Systems in a post-TRIPS world

Indices that approximate for the quality and strength of intellectual property (IP) systems are commonly used as variables in empirical international management studies. However, while international IP systems have radically transformed after the implementation of the TRIPS agreement, these contextual changes have not been accounted for in existing international management research approaches. This study examines the institutional context of IP systems in the post TRIPS implementation years by conceptualizing how IP Law on the books (regulations) and IP Law in practice (enforcement) combine. This enables the identification of two new contextual categories of IP systems that have not been conceptually, theoretically, or empirically captured in existing international management research. A review of the existing literature on indices measuring different aspects of national IP systems provides insights into how to improve future theoretical and empirical international management work that aims to study the effects of the context of IP systems in the post TRIPS era.

专利池中的权利滥用问题——美国专利权滥用规则的发展

专利池许可是一种较新而且较复杂的专利许可形态,专利池既有节省交易成本促进竞争的作用,又有容易造成专利权扩张形成专利权滥用的倾向.美国司法对专利权滥用的规制走过了一段从松到紧再到相对较松的历史历程,2005年的飞利浦诉美国国际贸易委员会案再次体现了对本身违法原则的摒弃.这对我国反垄断立法有一定的启示.     

新能源汽车产业专利池的形成机制

针对新能源汽车产业的模块化发展特征,采用动态博弈方法研究该产业中基于产业链的纵向一体化企业和纯上游研发企业专利池的形成机制。构建三阶段的动态博弈模型:第一阶段,专利所有权人决定是否组成专利池;第二阶段,企业根据许可方式来预测行业产量对于许可费率的反应函数;第三阶段,下游制造商进入市场,同时决定最终产品的产量来最大化其利润。根据博弈分析的结果,发现新能源汽车产业纵向一体化企业与纯上游研发企业组建一个专利池,那么无论是纵向一体化企业还是纯上游研发企业,它们获取的利润都要更为理想。同时专利池的组建也会使得下游市场产品总产量提高,价格降低。政府有关部门可以在许可费科学分配、研发合作以及法律法规建设等方面发挥强有力的引导作用,助力新能源汽车产业的专利池发展与长期稳定运营。
