The growing popularity of dynamic applications such as social networks provides a promising way to detect valuable information in real time. These applications create highspeed data that can be easily modeled as streaming graph. Efficient analysis over these data is of great significance. In this paper, we study the subgraph (isomorphism) search over streaming graph data that obeys timing order constraints over the occurrence of edges in the stream. We propose a solution to efficiently answer subgraph search, introduce optimizations to greatly reduce the space cost, and design concurrency management to improve system throughput. Extensive experiments on real network traffic data and synthetic social streaming data confirms the efficiency and effectiveness of our solution.

BackgroundRecent advances in omics technology have produced a large amount of liver-related data. A comprehensive and up-to-date source of liver-related data is needed to allow biologists to access the latest data. However, current liver-related data sources each cover only a specific part of the liver. It is difficult for them to keep pace with the rapid increase of liver-related data available at those data resources. Integrating diverse liver-related data is a critical yet formidable challenge, as it requires sustained human effort.ResultsWe present LiverWiki, a first wiki-based database that integrates liver-related genes, homolog genes, gene expressions in microarray datasets and RNA-Seq datasets, proteins, protein interactions, post-translational modifications, associated pathways, diseases, metabolites identified in the metabolomics datasets, and literatures into an easily accessible and searchable resource for community-driven sharing. LiverWiki houses information in a total of 141,897 content pages, including 19,787 liver-related gene pages, 17,077 homolog gene pages, 50,251 liver-related protein pages, 36,122 gene expression pages, 2067 metabolites identified in the metabolomics datasets, 16,366 disease-related molecules, and 227 liver disease pages. Other than assisting users in searching, browsing, reviewing, refining the contents on LiverWiki, the most important contribution of LiverWiki is to allow the community to create and update biological data of liver in visible and editable tables. This integrates newly produced data with existing knowledge. Implemented in mediawiki, LiverWiki provides powerful extensions to support community contributions.ConclusionsThe main goal of LiverWiki is to provide the research community with comprehensive liver-related data, as well as to allow the research community to share their liver-related data flexibly and efficiently. It also enables rapid sharing new discoveries by allowing the discoveries to be integrated and shared immediately, rather than relying on expert curators. The database is available online at http://liverwiki.hupo.org.cn/.

To achieve common prosperity is the fundamental goal of socialism, and the implementation of rural revitalization strategy is an inevitable requirement for achieving common prosperity. Based on the background of rural revitalization strategy, this paper summarizes the theories related to rural revitalization in line with China’s national conditions, clarifies the main tasks of rural revitalization planning in Guangdong, further analyzes the ways to promote rural revitalization planning in Guangdong, and on this basis, takes the rural revitalization planning of Youshan Township in Nanxiong City, which was concluded and promulgated in July 2022 under the auspices of the author, as an example, and discusses the four aspects of planning background, general requirements, main tasks and guarantee measures. This is with a view to providing certain reference and reference for the relevant functional departments to prepare and improve the rural revitalization plan.
