Dual intent view contrastive learning for knowledge aware recommender systems.

Knowledge-aware recommendation systems often face challenges owing to sparse supervision signals and redundant entity relations, which can diminish the advantages of utilizing knowledge graphs for enhancing recommendation performance. To tackle these challenges, we propose a novel recommendation model named Dual-Intent-View Contrastive Learning network (DIVCL), inspired by recent advancements in contrastive and intent learning. DIVCL employs a dual-view representation learning approach using Graph Neural Networks (GNNs), consisting of two distinct views: a local view based on the user-item interaction graph and a global view based on the user-item-entity knowledge graph.

Export competitiveness network of Chinese provincial agricultural products: E volution, performance, and influencing factors.

The development of top-tier agricultural product bases and demonstration zones aims to propel Chinese agriculture into the global market, form international competitiveness, and advance to the high end of the global industrial and value chain. This study contributes to the existing literature by investigating the performance and factors influencing the competitiveness of Chinese agricultural product exports at the provincial level, using a complex network perspective, and offers recommendations for improvement. In this regard, the article uses agricultural product export data from 2015 to 2022 to create export competitiveness networks of Chinese provincial agricultural products.

Promotion of microfracture-mediated cartilage repair by the intra-articular injection of Mg2.

Aims: Magnesium ions (Mg) play an important role in promoting cartilage repair in cartilage lesions. However, no research has focused on the role of Mg combined with microfracture (MFX) in hyaline-like cartilage repair mediated by cartilage injury. This study aimed to investigate the beneficial effects of the combination of MFX and Mg in cartilage repair.
