Multi-Agent Deep Reinforcement Learning with Contrastive Policy Diversification and Hierarchical Graph Networks for Urban Traffic Signal Control
Multi-Agent Reinforcement Learning (MARL) provides an effective approach for urban multi-intersection traffic signal control. However, existing methods have faced two fundamental challenges, policy homogenization and inefficient credit assignment. The former led to convergent agent policies that failed to adapt to heterogeneous traffic patterns, while the latter prevented agents from accurately evaluating their individual contributions to system …
Critical Role of Groundwater‐Dependent Vegetation in Mitigating Aeolian Erosion in a Hyper‐Arid Endorheic Basin
Groundwater‐dependent vegetation (GDV) plays a critical role as a natural barrier against aeolian erosion in dryland ecosystems. Despite its ecological significance, the full extent of GDV's functions remains not yet fully understood due to limitations in field data availability, spatial variability, and intricate groundwater‐vegetation dynamics. This study employs machine learning techniques to distinguish GDVs from non‐GDVs in the middle to low…
Contribution of soil macropores to water infiltration across different land use types in a desert–oasis ecoregion
Surface soil hydraulic properties play critical roles in controlling water infiltration, evaporation, and soil water storage, in‐turn affecting the evolution of soil pore structure in cultivated desert soils of arid areas. The variability in soil pores and hydraulic properties caused by conversion of native semidesert soils to agroforestry use alters soil water storage and water budget in the desert–oasis ecotone. The objective of this study was …
The features of main osmolytes, silicon and their coupling effects in improving drought resistance of the typical xerophytes in the desert areas of Northwest China
Succulent xerophytes (SX) and less succulent xerophytes (LSX) are able to accumulate inorganic ions and synthesize organic solutes (OS) to adapt to drought stress. Silicon (Si) is one of the five beneficial elements for plants and its importance to SX has been confirmed. In the study, the features of main osmolytes and Si were studied in SX and LSX species, and the coupling effects of inorganic ions were investigated in the SX H. ammodendron and …

Prevalence of premastication among children aged 6–36 months and its association with health
Premastication is thought to be an adaptive behavior in the introduction of complementary plant-bassed food to infants. It arouses controversy, however, because of the potential for transmitting saliva-born infectious diseases. The aim of this study was to explore whether premastication by healthy caregivers was associated with children's health and behavior. The data were collected as part of the Maternal and Infant Nutrition and Growth study. F…
Dietary diversity scores
Dietary diversity score is a valid indicator to evaluate micronutrient inadequacy in Chinese children, though there is still room for improvement of the method. Besides, the relationship between increase of dietary diversity and risk of obesity should be treated circumspectly
Consumption of sugar-sweetened beverages and its association with overweight among young children from China
Objective To fully understand the sugar-sweetened beverage (SSB) consumption status among Chinese young children and to explore its association with weight gain. Design In this cross-sectional study, data on sociodemographic characteristics, SSB intake and weight/height were collected by means of face-to-face interviews. The intake of SSB among young Chinese children in relation to their age, different characteristics and types of SSB consumed is…
