Emerging applications such as smart city infrastructures and virtual reality landscapes are setting rigorous benchmarks for 6G mobile networks, requiring elevated levels of confidentiality, integrity, nonrepudiation, authentication, and stringent access controls. Blockchain technology is heralded as a transformative enabler for meeting 6G standards, owing to its intrinsic attributes. However, a gap exists in the holistic investigation of blockchain's applicability in 6G realms, particularly addressing the “whether”, “when”, and“how” of its deployment. Present research trails in developing robust methodologies to gauge blockchain's efficacy within 6G use cases. Addressing this, our study introduces a novel confluence of blockchain with 6G networks, where data resides in distributed Hash tables(DHTs) while their hashes are secured in distributed ledger technology(DLT), harnessing blockchain's core strengths-immutability, traceability, and fortified security. We delineate seven specific 6G use cases poised for enhancement through blockchain integration,and scrutinize the rationale, nature, and timing of this convergence. Furthermore, we devise a comprehensive methodology for assessing blockchain's performance metrics and scalability in 6G environments. Our extensive experimental analyses evaluate the synergistic performance of this integration, revealing that the Quorum blockchain satisfactorily supports 80% of 6G scenarios. The findings suggest that, with appropriate configurations, consortium blockchains are well-equipped to fulfill the demanding performance and scalability requisites of 6G networks.

张新之《红楼梦》评点品第术语考论

红楼梦学刊 2023年第1期 81-97页

作者：高红豪上海第二工业大学外语与文化传播学院 201209

将“神品”“叙事能品”等品第术语运用于小说的文法批评,是张新之《红楼梦》评点的主要特色与理论贡献。这些品第术语常以文法加品第的形式组合存在,主要受明代经史评点影响。张新之在叙事与写人两个方面分别赋予品第以不同内涵,叙事... 详细信息

将“神品”“叙事能品”等品第术语运用于小说的文法批评,是张新之《红楼梦》评点的主要特色与理论贡献。这些品第术语常以文法加品第的形式组合存在,主要受明代经史评点影响。张新之在叙事与写人两个方面分别赋予品第以不同内涵,叙事上追求技巧与微言大义,写人上区分个性与逼真的艺术效果,从而体现了张新之的“红楼观”。张新之的理论贡献体现在品第术语的系统性运用、价值序列的构建与批评视角的拓展。通过对张新之品第批评话语的梳理考辨,既可以加深我们对《红楼梦》艺术特性的认识,也有助于我们建构具有本土化特色的中国古代小说理论话语体系。

为了在计算流程模型相似度时考虑到业务流程数据,解决以Artifact为中心的业务流程模型相似性度量问题,分析了业务流程执行过程中对数据的操作,提出了一种面向以Artifact为中心的业务流程相似度计算方法。对以Artifact为中心的流程模型的定义进行了扩展,增加了数据属性操作的描述;抽取Artifact数据属性的操作序列,将业务流程模型分解为Artifact数据属性操作序列集合;对数据属性操作序列进行分类,计算不同业务流程模型间数据属性操作序列相似度,进而得到以Artifact为中心的业务流程模型间的相似度。实验结果表明,该方法不仅体现了业务流程模型的数据操作特性,也体现了业务流程模型的行为,为以Artifact为中心的流程模型相似度计算提供了一种可行的方法。

品第批评是中国古代文学批评方法中的一种,最早源于《汉书》中的"九品论人",后经书画品第的发展,于明清两代被广泛借用到文学批评之中。明清小说中的品第批评主要存在于各种形态的评点之中,具有应用时间长、覆盖作品广等特点。其功能体现在对小说叙事、辞令、写人等多方面的等级评定,是我们研究明清小说批评理论的重要切入点。
