Electrocatalytic glucose oxidation reaction(GOR)has attracted much attention owing to its crucial role in biofuel cell ***,we load MoO_(3)nanoparticles on carbon nanotubes(CNTs)and use a discharge process to prepare a noblemetal-free MC-60 catalyst containing MoO_(3),Mo_(2)C,and a Mo_(2)C–MoO_(3)*** the GOR,MC-60 shows activity as high as 745μA/(mmol/L cm^(2)),considerably higher than those of the Pt/CNT(270μA/(mmol/L cm^(2)))and Au/CNT catalysts(110μA/(mmol/L cm^(2))).In the GOR,the response minimum on MC-60 is as low as 8μmol/L,with a steady-state response time of only 3 ***,MC-60 has superior stability and anti-interference ability to impurities in the *** better performance of MC-60 in the GOR is attributed to the abundant Mo sites bonding to C and O atoms at the MoO_(3)–Mo_(2)C *** Mo sites create active sites for promoting glucose adsorption and oxidation,enhancing MC-60 performance in the ***,these results help to fabricate more effi cient noble-metal-free catalysts for the fabrication of glucose-based biofuel cells.

Synchronous CODA opinion dynamics over social networks

第40届中国控制会议

作者： Kun Tang yiyi zhao Jiangbo Zhang Jiangping Hu School of Automation Engineering University of Electronic Science and Technology of China the School of Business Administration Southwestern University of Finance and Economics School of Science Southwest Petroleum University

The continuous opinion and discrete actions（CODA） model is a practical approach in the field of opinion dynamics to investigate how action observation can change an agent’s opinion and decision in a community. However, the original CODA model takes only a fixed number of agents’ action in the process of opinion updating when, in fact, the opinion of an individual in society will be influenced by a group of agents whose opinions are close to him/her. In this study, we develop a variant of the Hegelsman–Krause（HK） model that averages the opinions updated by the CODA rule after observing neighbors’ actions. Using this approach, we investigate the influence of social imitation on collective opinion evolution and decision making. We use a social network generated by the Barabasi–Albert（BA） algorithm to represent a social group. Simulation results show that agents’ opinions are more likely to be polarized after communicating with more neighbors. The impact of the level of biased-mindedness is also investigated. The results show that agents in a biased-minded social group could reach opinion stabilization faster than in a non-biased minded social group. In addition, the ratio of choice increases monotonically with the level of bias.

担保国义务包括保护环境等直接义务,也包括确保承包者履行合同并遵守"区域"制度等尽责义务。国际海洋法庭海底争端分庭的咨询意见澄清了担保国责任的履行方式与免责关键在于国内法的制定与执行,不过在"区域"开发阶段来临前需要进一步探讨与担保国责任承担范围与义务相关的问题。开发阶段担保国责任仍属于适当尽责的担保,与主要解决国际法上责任承担的国家责任存在着界限。《"区域"内矿产资源开发规章(草案)》中环境保护方面的内容涉及担保国的环境保护义务,为探讨国际环境法基本原则中共同但有区别的责任在担保国制度中的适用创造条件。此外,《开发规章(草案)》中管理局行使权力方面的内容涉及担保国制定与执行国内法的义务,将构成针对承包者的重复处罚问题,需要担保国与管理局合作协商解决。

商誉减值释放重大不利信号,公司主动计提减值的动机较弱,可能更多来自外部审计压力。审计个体行为受到审计市场结构影响,本文研究审计市场结构与客户商誉减值的关系。市场集中形成市场势力,整体上不利于对减值规避的监督,检验发现审计市场集中度与客户商誉减值负相关。该效应在非十大事务所显著强于前十大,小所由于定价劣势与技术劣势成为市场效率损失的主要挤压对象。此外,本土大所打破国际四大垄断后,审计市场结构的变化没有提升市场效率,进入前四的本土大所加剧了市场集中度与商誉减值的负相关。本文在审计市场的角度提出了影响公司商誉减值的外部因素,也为审计市场结构对其中个体的差异化影响提出新的分析思路。

第43届中国控制会议

作者： Junyi Yang Jianglin Dong yiyi zhao Yuan Peng Jiangping Hu School of Automation Engineering University of Electronic Science and Technology of China School of Business Administration Southwestern University of Finance and Economics Yangtze Delta Region Institute (Huzhou) University of Electronic Science and Technology of China

For group decision-making, the existing research mainly focuses on the macroscopic evolution of opinions and communities, while ignoring the microcosmic dynamics in trust relations. This paper addresses this gap by introducing a novel framework that explores the opinion evolution with community detection, specifically considering comprehensive trust relationships. Our approach integrates a trust-similarity score mechanism to illustrate the comprehensive trust relationships among agents in a social network. Building upon this, we employ the Hegselmann-Krause(HK) model and the label propagation algorithm(LPA) to simulate the process of opinion evolution and community detection. Experimental results reveal that when the trust-similarity score parameters stay below the critical value, the group eventually converges to a consensus accompanied by a high-quality community partition. Our framework is confirmed to be more effective in improving opinion consensus and community modularity compared to an alternative model that concentrates solely on opinion evolution and community detection.

基于网络观的语言研究已经成为语言分析的趋势之一。但不同语言单位层级、不同语言单位关系的选取导致了语言网络的差异。从词的同现网到句法网再到语义网所需要的语言学知识也逐步深化,该文旨在构建语义学理论支撑的语义网络,并把虚词纳入语义分析过程,分别以句法关系和语义关系作为联结,用Cytoscape构建了句法网和语义网。结果发现:语义网的直径、平均最短距离比句法网大,层级性比句法网差,聚集系数比句法网小,虚词节点"的""和""个"等有可能是局部的中心节点。
