Population mobility between cities significantly affects traffic congestion, disease spread, and societal well-being. As globalization and urbanization accelerate, understanding the dynamics of population mobility becomes increasingly important. Traditional population migration models reveal the factors influencing migration, while machine learning methods provide effective tools for creating data-driven models to handle the nonlinear relationshi…
Identify a sustainable afforestation pattern for soil carbon sequestration
Afforestation is considered to be an important means to improve the ecological environment and mitigate climate change. However, inappropriate vegetation restoration can result in severe soil desiccation and ecosystem degradation in water‐limited regions. Here, we evaluated the effects of six different afforestation patterns on soil moisture content, soil organic carbon (SOC) sequestration, and especially the conversion efficiency of the two on t…
Adverse childhood experiences, unhealthy lifestyle, and nonsuicidal self-injury
Background: Nonsuicidal self-injury (NSSI) is a serious public health problem. The role of adverse childhood experiences (ACEs) and lifestyle on the risk for NSSI is still underexplored, especially among college students. We aimed to investigate the association of ACEs with the risk of NSSI, and effect modifications by lifestyle among college students. Methods: A total of 18,723 college students from six universities were recruited through a mult…

The double-edged sword effect of social networking use intensity on problematic social networking use among college students
Different Roles of Academic Stress and Academic Expectation Stress in Emotional Problems and Internet Gaming Disorder Among Chinese Adolescents
Hydroclimatic changes in south-central China during the 4.2 ka event and their potential impacts on the development of Neolithic culture
The 4.2 ka event is widely presumed to be a globally widespread aridity event and has been linked to several episodes of societal changes across the globe. Whether this climate event impacted the cultural development in south-central China remains uncertain due to a lack of regional paleorainfall records. We present here stalagmite stable carbon isotope and trace element–based reconstruction of hydroclimatic conditions from south-central China. O…
Comparison of clinical outcomes and risk factors for Covid-19 infection in cancer patients without anticancer treatment and noncancer patients
Background Previous studies have shown that cancer patients have higher rates of coronavirus disease 2019 (COVID-19) infection and mortality than noncancer patients. However, the differences between cancer patients undergoing regular follow-up without anticancer treatment and noncancer patients with COVID-19 have remained insufficiently investigated. Methods A retrospective case–control study of 52 patients with COVID-19 infection was performed w…
