Cost-effectiveness of community-based artificial intelligence screening for retinopathy of prematurity
Background: Retinopathy of prematurity (ROP) is one of the leading causes of childhood blindness globally, but particularly in middle-income countries, where neonatal survival has improved faster than access to specialist ophthalmic care. Although telemedicine and artificial intelligence (AI)-assisted screening show promise for improving access to ROP screening, their economic value within decentralised health systems remains uncertain. To explor…
‘If you cherish your body, you shouldn’t get pregnant’
This paper engages with 'the bodily costs of childbearing' or the negative physical consequences of pregnancy and childbirth and examines their role in shaping Chinese female university students' fertility intentions. A thematic analysis informed by corporeal realism was conducted with 30 semi-structured interviews with female university students without childbearing experience. The findings reveal that women's fear of bodily costs originates fro…
Assessing the nonlinearity of wintertime PM 2.5 formation in response to precursor emission changes in North China with the adjoint method
While China’s clean air actions implemented since 2013 have been effective in mitigating PM 2.5 air pollution, the large emission reductions during the COVID-19 lockdown period in early 2020 did not similarly alleviate PM 2.5 pollution in North China, reflecting a distinct nonlinear chemical response of PM 2.5 formation to emission changes. Here we apply emission-concentration relationships for PM 2.5 diagnosed using the adjoint approach to quant…
High-resolution assessment of wind energy potential in the Hami region of Northwestern China
Wind energy plays a pivotal role in the global effort to mitigate climate change, with China emerging as a leader in renewable energy adoption. The Hami region in northwestern China stands out as a crucial area for wind power development, given its substantial wind resources and strategic importance in China’s energy landscape. However, existing studies on wind energy potential vary widely and involve large uncertainties due to sparse measurement…
Global assessment of spatiotemporal changes of frequency of terrestrial wind speed
Wind energy, an important component of clean energy, is highly dictated by the disposable wind speed within the working regime of wind turbines (typically between 3 and 25 m s −1 at the hub height). Following a continuous reduction (‘stilling’) of global annual mean surface wind speed (SWS) since the 1960s, recently, researchers have reported a ‘reversal’ since 2011. However, little attention has been paid to the evolution of the effective wind s…
Wind mediates the responses of net ecosystem carbon balance to climatic change in a temperate semiarid steppe of Northern China
As an important carbon sink to mitigate global climate change, the role of arid and semiarid grassland ecosystem has been widely reported. Precipitation and temperature changes have a dramatic impact on the carbon balance. However, the study of wind speed has long been neglected. Intuitively, wind speed regulates the carbon balance of grassland ecosystems by affecting the opening of vegetation stomata as well as near-surface moisture and temperat…
What drives the change of capacity factor of wind turbine in the United States
The capacity factor (CF) is a vital parameter used to quantify the performance and efficiency of a wind turbine. An increase in generation efficiency leads to higher wind power production, improving the economics within the growing global wind market. In this research, we use a data-driven statistical method to explore the contributions of the three main drivers of CF change: turbine aging, changes in wind speed, and technological improvements. W…
Mitigation of air pollutant impacts on rice yields in China by sector
Air quality management is a complex project involving the coordination of multiple sectors and has been identified as an important strategy for food security. However, little is known about how pollutant emissions from each sector affect agriculture. Each sector emits different precursors, resulting in varying impacts of their pollutants and aerosol-climate on rice yield. Therefore, we provide an assessment of air pollution impacts, including dir…
The impact of environmental protection tax on sectoral and spatial distribution of air pollution emissions in China
Environmental problems, associated with climate change and air pollution, have become increasingly serious for China in recent years, which have aroused great domestic and international concerns. To mitigate these problems with great efforts, the Chinese government has implemented the Environmental Protection Tax Law in the whole country since the beginning of 2018. Although the new tax law is perceived as an aggressive policy that tends to estab…
