Personalized news recommendation is the process of predicting the relevance of news to users and recommending news to user to fulfill their information needs. However, existing news recommendation methods extract semantic information from users and candidate news respectively, ignoring semantic interaction information between users and candidate news. Furthermore, previous models only use same node types for message passing, ignoring different characteristics and topology between different node types. In addition, existing methods learn news representations through text representations, ignoring semantic correlation information between entity relationships and texts. To solve these problems, we propose a personalized news recommendation model named CoHG. In our model, we design a collaborative fusion module to obtain semantic interaction information through interacting user history news with candidate news. Furthermore, we design a heterogeneous gated graph neural network that maps different node types into a same space to extract higher-order information in user graphs for message passing. Moreover, we design an enhanced relevant attention module to enhance semantic correlation information of text content by aggregating text representation and entity representation into a unified representation. Finally, we conducted experiments on MIND and Adressa datasets to compare with other baseline models. © 2024 IEEE.

In the field of engineering materials, achieving a balance between high strength and high toughness often poses a challenge. Typically, enhancing the toughness of ceramics involves incorporating a ductile metallic or polymeric phase;however, their application in high-temperature environments is constrained. Inspired by the biological materials, this work proposes all-ceramic composite with nacre-like structure, which was prepared utilizing 3D printing technology. Flexural strength was tested by three-point bending and fracture toughness was determined by SEVNB. The crack growth resistance capability was evaluated using the J-integral method. The effects of the content of polymethyl methacrylate (PMMA) microspheres in the weak phase and volume fraction of the strong phase on the flexural strength, fracture toughness, and progressive failure behavior of nacre-inspired composite ceramics were elucidated. The nacre-inspired Al2O3-ZrO2 composite ceramics were found to exhibit non-brittle failure due to the layered features, whilst the Al2O3-ZrO2 composite ceramics fractured catastrophically, though it is expected to have a higher failure stress. The step-like fracture mode enhances energy dissipation during crack propagation, thereby resulting in a higher fracture toughness of the nacre-inspired Al2O3-ZrO2 composite ceramics compared to Al2O3-ZrO2 composite ceramics. The findings can serve as valuable guidance for the design and fabrication of nacre-inspired composites. © 2025 Elsevier Ltd and Techna Group S.r.l.

Synthesis and design of hypercrosslinked porous organic frameworks containing tetraphenylpyrazine unit for high-performance supercapacitor

Journal of Polymer science 2024年第8期62卷 1629-1638页

Human society faces significant environmental challenges due to the rapid production and consumption of fossil fuels. Therefore, developing effective and environmentally friendly methods of generating and storing energy is essential. Hypercrosslinked polymers (HPPs) have become increasingly popular due to their diverse preparation methods, simple functionalization, large specific surface area, low cost, mild reaction conditions, high chemical and thermal stability, and small size. We synthesized two hypercrosslinked porous organic polymers using Friedel-Crafts reactions of 2,3,5,6-tetraphenyl pyrazine (Pyra) with 4,4′-bis(chloromethyl)biphenyl (BP), and dimethoxymethane (DDM), resulting in Pyra-BP-HPP and Pyra-DDM-HPP, respectively. The chemical structures and thermal stability of these polymers were confirmed through solid-state 13C NMR, FTIR, and TGA. The surface area of Pyra-BP-HPP and Pyra-DDM-HPP was determined to be 984 and 435 m2 g−1, respectively, with micro and mesoporous structures present. Pyra-BP-HPP displayed a high specific capacitance of 94 F g−1 at 1 A g−1, with a capacity retention of 95% after 2000 cycles, which can be attributed to its larger surface area, microporosity, and abundance of electron-rich phenyl rings when compared to Pyra-DDM-HPP. © 2023 Wiley Periodicals LLC.

This work reports the effects of activation temperatures on the porous development and electrochemical performance of activated carbons. Herein, activated carbons were prepared from the biowaste of mangosteen peel by using KOH activation at temperatures of 400, 600, and 800°C. The results demonstrate that the specific surface area increases with increasing the activation temperatures in which the well-developed porous structure after KOH activation at 800°C provides the highest specific surface area of 1039 m2g-1. At 600°C, the activated carbon delivers the highest specific capacitance value of 182 F g-1at a current density of 0.5 A g-1in 3 M KOH aqueous electrolyte. This is correlated well with its high micropore fractions（99%）. Moreover, it was found that the activation temperature changes the major contribution of oxygen-containing functional group on surface of activated carbon, which is beneficial for the enhancement of the specific capacitance value of activated carbon at the temperature of 600°C. This work suggests that the activation temperature is a key to optimizing the electrochemical performance of activated carbons. Overall, our activated carbons can be considered as a strong candidate for use as electrode materials in supercapacitors.

Radiology report generation is an essential task in the medical field, which aims to automate the generation of medical terminology descriptions of radiology images. However, this task currently suffers from several problems: 1) existing methods need to manually build knowledge graphs or templates (consuming time and effort) to introduce medical or prior knowledge to assist in report generation;2) previous models cannot handle the problem of data bias well (anomaly reports and anomaly descriptions make up only a tiny portion of the dataset), causing the models to ignore the learning of anomaly descriptions easily;3) existing approaches cannot robustly supervise the model, resulting in incomplete and inconsistent reports being generated. To address these issues, we propose a cross-modal interactive memory network based on fine-grained medical feature extraction. In our model, we design a cross-modal interactive memory network to automatically store and remember the required medical text knowledge and use this medical knowledge to help generate reports. Furthermore, we design an abnormal medical knowledge enhancement module to enhance the learning of abnormal fine-grained knowledge through the interaction of disease topics and their states to interact with text features. In addition, we design a cross-modal joint semantic loss unit to reduce semantic differences between different features and improve the visual representation ability of the model. We experimented and evaluated our model on MIMIC-CXR and IU-Xray datasets to compare with other baseline models. © 2024 IEEE.
