Objective: To analyze the literatures related to the nutrition of children with tumors at home and abroad, and sort out the current status, hotspots and frontiers of the research in this field, so as to provide a theoretical basis and reference for relevant research in China. Methods: The Web of Science and CNKI were searched for literatures related to nutrition of pediatric tumor patients since its establishment, and CiteSpace 6.1.R6 software was applied to visualize and analyze the nodes of countries, institutions and keywords. Results: A total of 53 articles in Chinese and 204 in English were included, with fluctuating upward trends in the number of publications. The largest number of publications with the strongest centrality was from the United States, and China was not ranked. Domestic publications were mainly from university-affiliated medical institutions, with Beijing Childrens Hospital Affiliated to Capital Medical University having the largest number of publications. Foreign publications were mainly from universities and medical institutions, with McMaster University and St. Jude Childrens Research Hospital having the largest number of publications. The main directions of domestic researchs were nutritional status and malnutrition, and the hot populations were children with malignant tumors and hematological tumors. The main directions of foreign researchs were nutritional status, malnutrition and body composition analysis, and the hot populations were children receiving chemotherapy or acute lymphoblastic leukemia. Conclusion: Through CiteSpace software to visualize the hotspots of children's oncology nutrition research at home and abroad directly, the relevant foreign researchs are more mature than the domestic, which can provide reference for researchers in China.

The research aims to investigate the effects of proportion and age of maintenance on the strength and economy of filling materials, in order to provide theoretical guidance and technical support for the management of coal mined-out area. Firstly, adjustments are made to the proportioning and maintenance age of the fill materials, and experiments are conducted to explore the strength performance of materials under different proportions. Secondly, GANs is utilized to expand the dataset, and an MLP-LSTM network is constructed to predict the strength of materials experiencing different maintenance ages under various proportions. Finally, integrating practical engineering applications, an economic viability prediction analysis is conducted to examine the cost of fill materials under different proportions and maintenance ages, along with their influencing factors. The results indicate that appropriate adjustments to proportioning can effectively enhance the strength of fill materials, whereas excessively high or low proportions may lead to unstable or surplus strength. Extending the maintenance age can to some extent improve the material's strength, but it also increases maintenance costs, necessitating a comprehensive balance in terms of economic viability. Consequently, this research offers a theoretical foundation and practical guidelines for optimizing mixture proportions and selecting appropriate curing ages, providing valuable insights for enhancing the efficiency and cost-effectiveness of coal mined-out area filling treatments.

In recent years, navigation has attracted widespread attention across various fields, such as geomatics, robotics, photogrammetry, and transportation. Modeling the navigation environment is a key step in building successful navigation services. While traditional navigation systems have relied solely on 2D data, advancements in 3D sensing technology have made more 3D data available, enabling more realistic environmental modeling. This paper primarily focuses on voxel-based navigation and reviews the existing literature that covers various aspects of using voxel data or models to support navigation. The paper first discusses key technologies related to voxel-based navigation, including voxel-based modeling, voxel segmentation, voxel-based analysis, and voxel storage and management. It then distinguishes and discusses indoor and outdoor navigation based on the application scenarios. Additionally, various issues related to voxel-based navigation are addressed. Finally, the paper presents several potential research opportunities that may be useful for researchers or companies in developing more advanced navigation systems for pedestrians, robots, and vehicles.

In recent years, extended reality (XR) technologies have emerged as transformative tools within the architectural design industry, offering immersive and interactive environments that enhance visualisation and collaboration. However, a significant gap remains between adopting these technologies in professional practises and integrating them into architectural design education. This study aims to bridge this gap by systematically reviewing XR applications in architectural design practises and exploring their potential integration into design studios. It specifically focuses on undergraduate graduation projects from the School of Architecture at Southeast University in China. Findings indicate that XR can transform traditional design approaches by refining design methods, extending design scopes, and encouraging the inclusion of diverse stakeholders. The paper also offers insights into optimising XR applications in architectural design education, providing strategic recommendations for technical advancements and academic curricula innovation, ultimately preparing students for technology-driven changes in professional practises.
