Does the Great Firewall Really Isolate the Chinese? Integrating Access Blockage With Cultural Factors to Explain Web User Behavior

The dominant understanding of Internet censorship posits that blocking access to foreign-based websites creates isolated communities of Internet users. We question this discourse for its assumption that if given access people would use all websites. We develop a conceptual framework that integrates access blockage with social structures to explain Web users’ choices, and argue that users visit websites they find culturally proximate and that access blockage matters only when such sites are blocked. We examine the case of China, where online blockage is notoriously comprehensive, and compare Chinese Web usage patterns with those elsewhere. Analyzing audience traffic among the 1000 most visited websites, we find that websites cluster according to language and geography. Chinese websites constitute one cluster, which resembles other such geolinguistic clusters in terms of both its composition and its degree of isolation. Our sociological investigation reveals a greater role of cultural proximity than access blockage in explaining online behaviors.     

Generalized matrix projective synchronization of general colored networks with different-dimensional node dynamics

This paper investigates the generalized matrix projective synchronization problem of general colored networks with different-dimensional node dynamics. A general colored network consists of colored nodes and edges, where the dimensions of colored node dynamics can be different in addition to the difference of the inner coupling matrices between any pair of nodes. For synchronizing a colored network onto a desired orbit with respect to the given matrices, open-plus-closed-loop controllers are designed. The closed-loop controllers are chosen as adaptive feedback and intermittent controllers, respectively. Based on the Lyapunov stability theory and mathematical induction, corresponding synchronization criteria are derived. Noticeably, many existing synchronization settings can be regarded as special cases of the present synchronization framework. Numerical simulations are provided to verify the theoretical results.     

以国际化理念深化科技和教育改革

中国革命的伟大胜利和改革开放的巨大成就都表明,国际化与本土化有机结合的重要性和必要性。开放性是实现国际化的前提,国际化是建设世界一流的基础。国际化就是把国际性融入到本土,把本土性拓展成国际,两者互为转化、相辅相成、相得益彰、形成一体。国际化已成为全球化发展不可逆转的趋势,以国际化理念全面深化科技和教育改革,率先推进中国特色国际化发展既是时代的要求,也是历史的必然。中国特色国际化就是要把国际化的过程和内涵及其目标与中国改革开放的实践相结合,充分发挥中国特色社会主义制度的优越性。科技和教育国际化不仅是我国在新的历史时期实现跨越发展的重要途径,也是实现教育梦、科技梦、中国梦的重要基础。中科院具有科研机构、学部、教育机构"三位一体"的独特优势,在科技和教育方面率先推进中国特色国际化发展将是实现习近平总书记在考察中科院时提出的"四个率先"的基础和前提。     

基于改进模糊集IFScom的λ-中介否定及应用

IFScom是一种区分矛盾否定关系、对立否定关系和中介否定关系的模糊集。针对模糊集IF-Scom在应用中的特点,对其中介否定算子作了进一步改进,使得中介否定集的λ-区间函数从[1-λ,1]扩充到[0,1],其分段比例函数的增减性更符合实际。在此基础上给出了λ-中介否定集在模糊入侵检测中的应用,仿真实验表明该中介否定集在模糊知识的"否定"区分、处理和推理上是有效的。     

运动员稀氧区域训练对肌肉纤维耐久力的影响

目的:研究运动员稀氧区域训练对肌肉纤维耐久力的影响。方法:分析18名运动员在常氧和高原低氧(模拟海拔4500 m递增负荷运动时,低氧通气反应速率、最大摄氧量以及最大耐力持续时间三个肌肉纤维耐久力评估指标的变化情况。结果:高原低氧训练时运动员低氧通气速率和最大耐力持续时间显著高于常氧对应值,高原低氧训练时,运动员最大摄氧量低于常氧对照组。高原低氧训练组,运动员在4个不同功率等级低氧通气速率,均高于常氧对应值,低氧通气速率在50%、75%以及100%最大功率时显著高于常氧对应值,最大摄氧量在各相对功率等级中,无显著性差异。运动员的低氧通气反应速率在高原低氧训练组至75%最大功率阶段降低,在75%至100%最大功率阶段基本保持平稳上升,不同相对强度下低氧训练组运动员最大摄氧量较常氧对应值显著降低。结论:高原运动训练下运动员肌肉纤维耐久力增强,疲劳时间降低,可提高运动员的运动能力。     

Microfluidic reactors for visible-light photocatalytic water purification assisted with thermolysis

Photocatalytic water purification using visible light is under intense research in the hope to use sunlight efficiently, but the conventional bulk reactors are slow and complicated. This paper presents an integrated microfluidic planar reactor for visible-light photocatalysis with the merits of fine flow control, short reaction time, small sample volume, and long photocatalyst durability. One additional feature is that it enables one to use both the light and the heat energy of the light source simultaneously. The reactor consists of a BiVO₄-coated glass as the substrate, a blank glass slide as the cover, and a UV-curable adhesive layer as the spacer and sealant. A blue light emitting diode panel (footprint 10 mm × 10 mm) is mounted on the microreactor to provide uniform irradiation over the whole reactor chamber, ensuring optimal utilization of the photons and easy adjustments of the light intensity and the reaction temperature. This microreactor may provide a versatile platform for studying the photocatalysis under combined conditions such as different temperatures, different light intensities, and different flow rates. Moreover, the microreactor demonstrates significant photodegradation with a reaction time of about 10 s, much shorter than typically a few hours using the bulk reactors, showing its potential as a rapid kit for characterization of photocatalyst performance.
