Research on the Legal Framework of Content Regulations for Network Platforms

In the era of the Internet,various network platforms have evolved into new hubs for information dissemination.Currently,China has established a platform-centered content regulation framework,wherein platforms proactively enforce content regulations in accordance with legal censorship obligations.Additionally,platform policies and user agreements augment their authority in content regulation.The platforms can achieve cost-effective and highly efficient content regulation by leveraging their strategic advantages enabled by their own technical capabilities and extensive coverage.The platform self-regulation model,however,still faces challenges.First,accurately evaluating content remains a formidable task;second,ensuring effective platform publicity through self-regulation poses difficulties;third,users may potentially face disadvantages due to the platform’s right of self-regulation;and fourth,digital copyright owners face challenges when defending digital copyright disputes under the safe harbor rule.Therefore,it is imperative to establish,review,and revise the legal framework for content regulation of network platforms in order to enhance the efficiency of their governance systems.The formulation of the legal framework for content regulation of network platforms may encompass the following aspects:rationalizing obligations pertaining to platform content regulations,enhancing supervision over platform self-regulation,and establishing a dual-track responsibility system for digital copyright content regulation.This will ensure a harmonious balance among public interests,users’personal rights and interests,and commercial benefits through regulating the content on network platforms.

Experimental Study of Primary School Students’Independent Reading Based on the Network Teaching Platform

The development of information technology, especially the rise of online teaching platforms, has changed the way people read and the methods they use. Under this influence, primary school students’ independent reading has also been changed. However, due to limited self-control and understanding, primary school students face certain difficulties when using online teaching platforms for independent reading. Advantages and disadvantages of distance learning based on the network teaching platform were summarized in this paper. A one-year experiment study was carried out on our school fifth-grade students in independent reading using WeChat campus platform considering their current situation and existing problems of independent reading. In experiment study an independent reading mode was introduced. The results show that this reading mode can significantly improve students’ independent reading ability.

Parametric Study on the Behavior of An Innovative Subsurface Tension Leg Platform in Ultra-Deep Water

This study focuses on a new technology of Subsurface Tension Leg Platform （STLP）, which utilizes the shallow- water rated well completion equipment and technology for the development of large oil and gas fields in ultra-deep water （UDW）. Thus, the STLP concept offers attractive advantages over conventional field development concepts. STLP is basically a pre-installed Subsurface Sea-star Platform （SSP）, which supports rigid risers and shallow-water rated well completion equipment. The paper details the results of the parametric study on the behavior of STLP at a water depth of 3000 m. At first, a general description of the STLP configuration and working principle is introduced. Then, the numerical models for the global analysis of the STLP in waves and current are presented. After that, extensive parametric studies are carried out with regarding to SSP/tethers system analysis, global dynamic analysis and riser interference analysis. Critical points are addressed on the mooring pattern and riser arrangement under the influence of ocean current, to ensure that the requirements on SSP stability and riser interference are well satisfied. Finally, conclusions and discussions are made. The results indicate that STLP is a competitive well and riser solution in up to 3000 m water depth for offshore petroleum production.

Experimental Study on the Hydrodynamic Performance of a Heaving Buoy Assembled on a Net Cage Platform

To take advantage of the abundance of both fishery and wave energy resources in offshore sea areas,a novel floating platform with a heaving buoy-based wave energy converter(WEC)assembled with a set of net cages is presented in this work.The floating WEC system provides a power supply,while the net cages are used for aquaculture.It is designed to have an independent and self-operation breeding function.An experimental study is carried out to investigate the hydrodynamic performance of the device in a wave tank considering the factors of net cages,draft depth,and power take-off,and results show that these variables have significant effects on wave energy capture.Incident waves with short periods cause intense interactions that allow the device to undergo large relative motion.The draft depth could be determined according to wave period rather than wave height.This study also explores the response amplitude operator of the device and determines its resonance scope.The experimental results could provide reliable information for future studies on phase differences and the design of two-body WECs.

Biomaterial-based platforms for cancer stem cell enrichment and study

Cancer stem cells(CSCs)are a relatively rare subpopulation of tumor cell with self-renewal and tumorigenesis capabilities.CSCs are associated with cancer recurrence,progression,and chemoradiotherapy resistance.Establishing a reliable platform for CSC enrichment and study is a prerequisite for understanding the characteristics of CSCs and discovering CSC-related therapeutic strategies.Certain strategies for CSC enrichment have been used in laboratory,particularly fluorescence-activated cell sorting(FACS)and mammosphere culture.However,these methods fail to recapitulate the in vivo chemical and physical conditions in tumors,thus potentially decreasing the malignancy of CSCs in culture and yielding unreliable research results.Accumulating research suggests the promise of a biomaterial-based three-dimensional(3 D)strategy for CSC enrichment and study.This strategy has an advantage over conventional methods in simulating the tumor microenvironment,thus providing a more effective and predictive model for CSC laboratory research.In this review,we first briefly discuss the conventional methods for CSC enrichment and study.We then summarize the latest advances and challenges in biomaterial-based 3 D CSC platforms.Design strategies for materials,morphology,and chemical and physical cues are highlighted to provide direction for the future construction of platforms for CSC enrichment and study.

Study on Security of NGN Service Platform

This article discusses the security of the NGN service platform in terms of the open service interface and service deployment. It thinks that security of the open service interface can be solved by adding the service access gateway and service management platform.

科研仪器平台评价体系的比较研究

随着科技投入持续增加,科研仪器平台作为一种新型社会组织,与开放共享运行和评价考核一同受到广泛关注。然而,围绕科研仪器平台开放共享运行的评价体系还有待于进一步研究,以便明晰评价工作的效用和现实内涵。本文以中国科学院所属的科研仪器平台为例,基于管理部门目前公布的开放共享考核评价结果,从效率和效益评价的视角对评价工作进行排序分析和因果逻辑研究,旨在以不同评价方式结果差异的检验解析评价体系的合理性和适用性。结果表明,不同评价体系对应不同的结果,管理部门现行评价关注集约化运行的仪器设备开放率、使用率和共享率,兼顾实验技术人才队伍建设和稳定情况,导致这些差异的主要原因在于不同评价体系对多种属性指标的赋权有异。研究结论可为科研仪器平台评价体系的完善提供参考,为平台高效稳定运行和绩效提升提供合理指导,为创新资源的优化配置和效能提升提供决策依据。

排水方式及加载条件对三筒型基础水平承载的影响

以三筒型基础为研究对象,分析吸力筒筒高、加载角度、加载速度以及排水条件对其承载性能的影响。研究表明,在其他3种影响因素不变的情况下,随着筒裙高度的增大,三筒基础的水平承载力提高;不排水条件下,加载速度明显影响筒型基础水平承载力和筒内孔隙水压力,排水条件下加载速度对筒型基础的水平承载力影响有限;加载角度不同,筒型基础的水平承载力最大增加1倍;不排水条件较排水条件可致使水平极限承载力最大增幅达149%。因此,实际工程中,沉放三筒型基础后,宜关闭筒顶阀门,有助于筒型基础保持较好的水平承载能力。
