[Objective] The aim of this study was to reveal the differences in the driving mechanisms of land expansion between resource-based cities and non-resource-based cities, which could provid references for the formulation of land use policies for the two types of cities. [Methods] Based on a research framework for the differences in driving mechanisms of land expansion in these two types of cities, 273 prefecture-level and above cities were selected as research samples, with data from 2003 to 2020. Comparative analysis, urban expansion intensity index, and panel regression model were used to explore the differences in the spatial expansion driving mechanisms of these cities. [Results] The results show that: (1) From 2003 to 2020, the built-up area of both types of cities showed a trend of expansion, and the average expansion speed of resource-based cities was lower than that of non-resource-based cities. From the perspective of development stage, the expansion speed of resource-based cities showed a trend of growth>mature>regenerative>exhausted type; From the perspective of resource endowment types, the expansion speed of non-metallic, non-ferrous, and oil and gas cities was faster than the average level of resource-based cities. (2) There are differences in the driving mechanisms of spatial expansion between the two types of cities. The population size, transportation development level, investment in science and technology, and environmental quality have a stronger driving effect on the spatial expansion of resource-based cities; The level of economic development, industrial structure, and resource endowment have a stronger driving effect on the spatial expansion of non-resource-based cities.(3) There are differences in the driving mechanisms of spatial expansion in resource-based cities at different stages of development. The level of transportation development and investment in technology have a stronger driving effect on growth- oriented cities; The level of economic development has a stronger driving effect on mature cities; The driving force of environmental quality on declining and regenerative cities is stronger. [Conclusion] The average expansion speed of resource-based cities in China is slower than that of non-resource-based cities; The population size, transportation development level, investment in science and technology, and environmental quality，the level of economic development, industrial structure, and resource endowment are primary factors driving the spatial expansion of cities. Different driving mechanisms are identified for the expansion of the two types of cities and among different types of resource-based cities.

[Objective] Agricultural heritage systems represent the harmonious human-nature relationship developed through long history of agricultural practices. With residents as the key stakeholder in agricultural heritage sites, improvement of residents’ well-being is among the fundamental goals of sustainable development. With the potential to showcase the high ecological and cultural values of agricultural heritage systems, tourism is considered an important path for the sustainable development of agricultural heritage sites. Therefore, exploring tourism impacts on residents’ well-being is of great theoretical and practical significance in promoting high-quality development of agricultural heritage sites. [Methods] This study took Dayutang and Qingkou Villages of Hani Rice Terraces in Yuanyang County, Yunnan Province as case study sites. An evaluation index with a total of 18 indicators was constructed to measure residents’ well-being in agricultural heritage sites, including six dimensions of economic conditions, living environment, social relations, educational resources, health and safety, and conservation and development. A quantitative resident questionnaire survey and qualitative semi-structured interviews were engaged to measure and compare the level of residents’ well-being and tourism impacts on residents’ well-being. [Results] The results are as follows: First, the level of residents’ well-being in the agricultural heritage sites varied greatly, with the highest level of well-being at 0.8516 and the lowest at 0.2321, and the mean value was 0.5641. Second, factors such as participation in tourism development, annual household income, age of residents, and education level demonstrated significant effects on the level of residents’ well-being. Third, this study examined heterogeneity in the perceived impacts of tourism development among residents of different backgrounds. Perceived changes in economic conditions, living environment, and conservation and development demonstrated significant positive effects on the level of residents’ well-being. However, perceived changes in social relationships, educational resources, and health and safety had insignificant effects on the level of residents’ well-being. [Conclusion] Therefore, in the process of tourism development, local governments should encourage the intergration of new livelihoods to local residents’ traditional livelihoods and enhance their participation in agricultural heritage tourism, thus striving to achieve a balance for tourism development, agricultural heritage conservation and residents’ well-being.

Highlights Interpenetrating phase composites (IPCs) can combine the advantages of each component and have a good application prospect. IPCs were prepared by combining open‐cell aluminum foam (AF) and epoxy resin (EP) in three‐dimensional space in this study. Different contents of silica powder (SP, 80, 100, 120, and 140 wt%) were added to EP to improve the compressive and three‐point bending properties of IPCs. In the bending test, acoustic emission (AE) was applied to track the bending deformation of the samples, and k‐means clustering algorithm was applied to identify the damage modes. The compressive and bending properties of IPCs increased first and then decreased with the increase of SP content, and reached the maximum when the SP content was 100 wt%, with a compressive yield strength of 74.6 MPa and a bending peak load of 1.96 kN. The performance degradation was mainly attributed to the AF/EP debonding due to SP distribution at the interface. The X‐type shear band and EP/AF debonding appeared in compression failures of AF and IPCs, respectively. The AE clustering results showed that under bending load, plastic deformation of matrix (60–200 kHz) and fracture failure (230–340 kHz) modes appeared in AF, while EP/AF debonding (60–120 kHz), EP failure (120–230 kHz) and plastic deformation of foam matrix (230–250 kHz) modes appeared in IPCs. Silica powder was added to improve compressive and bending properties of IPCs. Acoustic emission was used to monitor bending of foam and IPCs firstly. k‐means clustering was used to identify and classify bending damage patterns. [ABSTRACT FROM AUTHOR]

This article discusses the dysbiosis of the oral-gut microbiome in patients with polycystic ovary syndrome (PCOS) and its implications for noninvasive diagnosis. PCOS is a common reproductive endocrine disorder that affects women of reproductive age. The study analyzed the oral and gut microbiome of PCOS patients and healthy controls and identified differences in microbial composition and functionality between the two groups. The findings suggest that the oral and gut microbiota may serve as potential predictive markers for PCOS diagnosis, and combining microbial indicators with clinical indices can optimize the accuracy of PCOS discrimination.

This article discusses a framework for drug repurposing using a multiscale fusion network. The authors constructed an integrated drug similarity network (iDSN) based on chemical structure and drug target sequence data to infer potential drug pathways and facilitate drug repurposing. The iDSN demonstrated superior performance compared to single-property drug similarity networks, and evaluation using benchmark datasets confirmed its stronger correlations with drug annotations. The framework also identified drug clusters with enrichment annotations on gene ontology and pathway analyses, suggesting potential drug repositioning opportunities. Overall, this scalable framework provides insights into downstream pathways and drug repurposing based on drug structural properties. [Extracted from the article]

Two-dimensional transition metal dichalcogenides (2D-TMDs) possess appropriate bandgaps and interact via van der Waals (vdW) forces between layers, effectively overcoming lattice compatibility challenges inherent in traditional heterojunctions. This property facilitates the creation of heterojunctions with customizable bandgap alignments. However, the prevailing method for creating heterojunctions with 2D-TMDs relies on the low-efficiency technique of mechanical exfoliation. Sb2Te3, recognized as a notable p-type semiconductor, emerges as a versatile component for constructing diverse vertical p–n heterostructures with 2D-TMDs. This study presents the successful large-scale deposition of 2D Sb2Te3 onto inert mica substrates, providing valuable insights into the integration of Sb2Te3 with 2D-TMDs to form heterostructures. Building upon this initial advancement, a precise epitaxial growth method for Sb2Te3 on pre-existing WS2 surfaces on SiO2/Si substrates is achieved through a two-step chemical vapor deposition process, resulting in the formation of Sb2Te3/WS2 heterojunctions. Finally, the development of 2D Sb2Te3/WS2 optoelectronic devices is accomplished, showing rapid response times, with a rise/decay time of 305 μs/503 μs, respectively. [ABSTRACT FROM AUTHOR]
