作者： Jingyan Zhang Tao Hu Qingshen Sun Engineering research center of Agricultural Microbiology Technology， Ministry of Education & Heilongjiang Provincial Key Laboratory of Plant Genetic Engineering and Biological Fermentation Engineering for Cold Region & Key Laboratory of Microbiology， College of Heilongjiang Province & School of Life Sciences， Heilongjiang University

Lactic acid bacteria (LAB) exopolysaccharides (EPS) reveal high safety and multiple activities， and are typical postbiotics produced by LAB during fermentation. In this paper， 6583 articles on LAB-EPS from web of science and ELSEVIER databases were retrieved， and 236 articles related to this review were screened. The EPS from 90 LAB strains were summarized in terms of their extraction methods， yield， molecular weight， monosaccharide composition， glycosidic bond configuration and the structural and activity relationships (SARs). However， there exist great challenges as for the low yield and high cost in EPS production. Therefore， this review further elaborated the mechanism of EPS secretion， the anabolic pathway of EPS， the structure and mechanism of key enzymes involving in EPS synthesis process， the prospect of gene regulation for EPS secretion， and proposed the engineering strategies for increasing EPS yield or tailored EPS design in recent years. In addition， CRISPR/Cas9 gene editing technology was also discussed in the production control of EPS in LAB. Finally， the engineering strategy of increasing EPS yield in recent years was proposed. This work might provide important theoretical support for the production and application of LAB-based EPS.

Multi-User Semantic Fusion for Semantic Communications over Degraded Broadcast Channels

China Communications 2024年第10期21卷 86-100页

作者： Wu Tong Chen Zhiyong Tao Meixia Xia Bin Zhang Wenjun Cooperative Medianet Innovation center Shanghai Jiao Tong UniversityShanghai 200240China

Degraded broadcast channels(DBC) are a typical multiuser communication scenario, Semantic communications over DBC still lack in-depth research. In this paper, we design a semantic communications approach based on multi-user semantic fusion for wireless image transmission over DBC. The transmitter extracts semantic features for two users separately and then effectively fuses them for broadcasting by leveraging semantic similarity. Unlike traditional allocation of time, power, or bandwidth, the semantic fusion scheme can dynamically control the weight of the semantic features of the two users to balance their performance. Considering the different channel state information(CSI) of both users over DBC,a DBC-Aware method is developed that embeds the CSI of both users into the joint source-channel coding encoder and fusion module to adapt to the *** results show that the proposed system outperforms the traditional broadcasting schemes.

Examining the pathway and mechanism of comprehensive land consolidation through the lens of rural neo-endogenous development

引用

Journal of Geographical Sciences 2024年第9期34卷 1739-1760页

作者： LUO Xiuli JIN Xiaobin LIU Xiaojie HONG Buting ZHOU Yinkang School of Geography and Ocean Science Nanjing UniversityNanjing 210023China Key Laboratory of Coastal Zone Exploitation and Protection Ministry of Natural ResourcesNanjing 210023China Key Laboratory of Carbon Neutrality and Territory Optimization Ministry of Natural ResourcesNanjing 210023China Jiangsu Province Land Consolidation and Ecological Restoration research center Nanjing 210023China

Land consolidation(LC) stands as a globally recognized strategy for rural development. In China, it has evolved towards comprehensive land consolidation(CLC) to support the rural revitalization initiative. However, there are ongoing challenges in understanding CLC's specific pathway and mechanism, particularly its role in stimulating rural endogenous development. This study aims to investigate the localization process of international experiences, examine the pathway of CLC, and scrutinize its mechanism in rural development from a novel perspective of neo-endogenous development. Field research and semi-structured interviews were conducted in Nanzhanglou village, renowned for its early adoption of CLC practices inspired by German experiences since 1988. Overall, key findings underscore the advantages of CLC in spatial restructuring, industrial development, and human capital enhancement in rural areas. Additionally, international experiences emerge as crucial exogenous forces, primarily by knowledge embedding, which catalyzes rural neo-endogenous development via the “resource-engagement-identity-endogenous” mechanism. Collectively, by introducing a neo-endogenous theoretical framework, this study offers valuable insights into the CLC implementation in China and beyond, and emphasizes the positive impact of knowledge embedding as an exogenous force in promoting rural neo-endogenous development to address existing research gaps. Recommendations for sustainable rural development involve enhancing rural planning practicality, governance capacity, and local leadership, while prioritizing agricultural modernization and increasing investments in education and vocational training to ensure that villagers benefit from industrial development.
