Together with the big data movement, many organizations collect their own big data and build distinctive applications. In order to provide smart services upon big data, massive variable data should be well linked and organized to form Data Ocean, which specially emphasizes the deep exploration of the relationships among unstructured data to support smart services. Currently, almost all of these applications have to deal with unstructured data by integrating various analysis and search techniques upon massive storage and processing infrastructure at the application level, which greatly increase the difficulty and cost of application development. This paper presents D-Ocean, an unstructured data management system for data ocean environment. D-Ocean has an open and scalable architecture, which consists of a core platform, pluggable components and auxiliary tools. It exploits a unified storage framework to store data in different kinds of data stores, integrates batch and incremental processing mechanisms to process unstructured data, and provides a combined search engine to conduct compound queries. Furthermore, a so-called RAISE process modeling is proposed to support the whole process of Repository, Analysis, Index, Search and Environment modeling, which can greatly simplify application development. The experiments and use cases in production demonstrate the efficiency and usability of D-Ocean.

The aim of this paper is to present the dynamic analyses of the system involving various damping models. The assumed frequency-dependent damping forces depend on the past history of motion via convolution integrals over some damping kernel functions. By choosing suitable damping kernel functions of frequency-dependent damp- ing model, it may be derived from the familiar viscoelastic materials. A brief review of literature on the choice of available damping models is presented. Both the mode superposition method and Fourier transform method are developed for calculating the dynamic response of the structural systems with various damping models. It is shown that in the case of non-deficient systems with various damping models, the modal analysis with repeated eigenvalues are very similar to the traditional modal analysis used in undamped or viscously damped systems. Also, based on the pseudo-force approach, we transform the original equations of motion with nonzero initial conditions into an equivalent one with zero initial conditions and therefore present a Fourier transform method for the dynamics of structural systems with various damping models. Finally, some case studies are used to show the application and effectiveness of the derived formulas.

The perovskite transition metal oxide(TMO) has been considered in electrocatalysis for the modern clean energy technologies as its high electrochemical activity and low cost. The atomic scale engineering to the local stoichiometry of single crystal TMO provides a clue of the relation between electronic structure and catalytic performance. Here we report a hydrogen evolution reaction(HER) activity enhancement ~ 1761% of Bi_(0.85)Sr_(0.15)FeO_3 compared to the pure BiFeO_3. By the systemic investigation of the Sr doping level of Bi_(1-x)Sr_xFeO_3(BSFO), it is found that the HER enhancement originates from the improvement of ferromagnetism of BSFO without obvious scarification of the ferroelectricity at the room temperature. The multiple ferroic orderings in BSFO are beneficial for HER activity, which offers the strengthen of hybridization of Fe 3d and O2 p orbitals from the view of ferromagnetism, and the assistance of electron drift by spontaneous electric polarization. Our study not only affords the strategy of developing multiple ferroic orderings in TMO, but also facilitates the atomic scale understanding of the improved HER activity.

中华优秀传统文化与科学社会主义价值观主张的高度契合是经由文化建构主体在两者“先在契合”的基础上进行理论创造和思想形塑而后形成的。研究两者从“先在契合”向“高度契合”转化发展的内在逻辑,是现实实践和理论发展的双重需要。中华优秀传统文化与科学社会主义价值观主张的先在契合性、各自转化发展的理论诉求、谋求中华民族伟大复兴的现实需要共同构成了中华优秀传统文化与科学社会主义价值观主张由“先在契合”向“高度契合”转化发展的可能性与必要性前提。中国共产党和中国人民作为文化建构主体,分别担当了由“先在契合”向“高度契合”转化过程中的领导主体和实践主体角色,是挖掘并拓展契合点位与契合路径、供给转化发展动力、赋予“高度契合”以合法性和正当性的主体力量。借言赋义、理念诠释以及制度建构是实现中华优秀传统文化与科学社会主义价值观主张由“先在契合”向“高度契合”顺利转化的具体方式和实践路径,通过用中华传统语词概念表述科学社会主义价值观、将科学社会主义价值观与中国人民日用而不觉的价值理念相衔接以及用制度建构承载具有中国特色的科学社会主义价值观主张,实现了中华优秀传统文化与科学社会主义价值观主张在概念、理念、制度等层面由浅入深、由理论到实践、由抽象到具体的高度契合。
