Soil Carbon and Nutrient Losses From Farmland Wind Erosion and Required Fertilizer Compensation in the North China Plain
Farmland wind erosion causes significant losses of soil organic carbon (SOC) and essential nutrients, reducing soil fertility, diminishing crop yields, and causing long‐term environmental degradation. Unclear relationships between nutrient losses and fertilizer compensation hinder effective soil conservation strategies. Here, we quantified the losses of SOC, nitrogen (N), and phosphorus (P) using the parameterized Wind Erosion Prediction System (…
Nested case-control study investigating factors affecting initial adoption of HIV self-testing among men who have sex with men in Guangzhou, China
Background: China has been exploring HIV self-testing (HIVST) among men who have sex with men (MSM) since 2014. Currently, both non-profit and commercial initiatives HIVST services have achieved comprehensive coverage. Investigating the factors influencing the initial adoption of HIVST among MSM in this context can help develop tailored HIVST service strategies of and further promote HIVST adoption among MSM communities. Methods: We selected 230 …
High transmission risk in HIV-1 molecular transmission network among MSM is related to unsafe sexual behavior and adverse childhood experiences
Background: Molecular transmission networks enable successful identification of core transmitters compared to traditional epidemiological surveillance; however, behavioral characteristics and psychological drivers of these spreaders remain poorly characterized. Adverse childhood experiences (ACEs) are significantly more common among HIV-positive individuals than in the general population; yet empirical evidence showing that ACEs increase transmis…
A new perspective on socioeconomic drought
In drought studies, a standardized index has better applicability, and a distributed index can improve our ability to identify the spatial aspects of droughts. However, for socioeconomic drought, none of the existing indices is both spatially distributed and standardized. To fill this gap, this study proposes a novel index, Distributed Standardized SocioEconomic Drought Index (DSSEDI), to accurately identify socioeconomic drought over time and sp…

Identifying Spatiotemporal Patterns of Multiscale Connectivity in the Flow Space of Urban Agglomeration in the Yellow River Basin
The United Nations Sustainable Development Goals (SDGs) and the rise of global sustainability science have led to the increasing recognition of basins as the key natural geographical units for human–land system coupling and spatial coordinated development. The effective measurement of spatiotemporal patterns of urban connectivity within a basin has become a key issue in achieving basin-related SDGs. Meanwhile, China has been actively working towa…
Improving educational equity by maximizing service coverage in rural Changyuan, China
Ensuring inclusive and equitable quality education is a primary goal in the United Nations' agenda for sustainable development. Under this global initiative, China has been striving to achieve equitable education in rural areas through the planning and development of rural schools. To this end, the paper focuses on the rural school planning issue by proposing an evaluation-optimization-validation framework in a case study in Changyuan, a county-l…
Willingness to receive the Covid-19 vaccine among HIV positive men who have sex with men in China
Our study showed that HIV-positive MSM had a high willingness to receive the COVID-19 vaccination. Targeted interventions such as health education should be conducted among MSM with HIV infection to enhance COVID-19 vaccine uptake
Few-Shot Building Footprint Shape Classification with Relation Network
Buildings are important entity objects of cities, and the classification of building shapes plays an indispensable role in the cognition and planning of the urban structure. In recent years, some deep learning methods have been proposed for recognizing the shapes of building footprints in modern electronic maps. Furthermore, their performance depends on enough labeled samples for each class of building footprints. However, it is impractical to la…
Vulnerability Identification and Cascading Failure Spatiotemporal Patterns on Road Network under the Rainstorm Disaster
Road vulnerability is crucial for enhancing the robustness of urban road networks and urban resilience. In medium or large cities, road failures in the face of unexpected events, such as heavy rainfall, can affect regional traffic efficiency and operational stability, which can cause high economic losses in severe cases. Conventional studies of road cascading failures under unexpected events focus on dynamic traffic flow, but the significant drop…

The classification and recognition of the shapes of buildings in map space play an important role in spatial cognition, cartographic generalization, and map updating. As buildings in map space are often represented as the vector data, research was conducted to learn the feature representations of the buildings and recognize their shapes based on graph neural networks. Due to the principles of graph neural networks, it is necessary to construct a …
Multidimensional Urban Vitality on Streets
Urban vitality is a key indicator for measuring urban development. This topic has been trending in urban planning and sustainable development, and significant progress has been made in measuring single indicators of urban vitality based on parcel or block units. With the continuous development of smart sensing technology, multisource urban data are becoming increasingly abundant. The application of such data to measure the multidimensional urban …
