The current study investigated the relationship between COVID-19 prevention burnout and emotional symptoms (depression and anxiety) among 1,837 Chinese college students and the underlying mechanisms. Results from moderated mediation analysis revealed that the association between COVID-19 prevention burnout and emotional symptoms was mediated by psychological inflexibility (β = 0.20, 95%CI = [0.10, 0.19]). Also, COVID-19 prevention burnout's direct and indirect effects on emotional symptoms were more substantial for students with high susceptibility to emotional contagion than those with low susceptibility. These findings contribute to understanding how COVID-19 prevention burnout relates to emotional symptoms and provide a new perspective for interventions promoting students' psychological flexibility, particularly those with higher susceptibility to emotional contagion.

Based on a Driving Forces-Pressure-State-Impact-Response (DPSIR) model, this paper takes a macroenvironmental, socioeconomic perspective to build an evaluation model to address sustainable Chinese wind power developments and to quantize the development results. From a combination of entropy weight and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method, the sustainable wind power development level in China is examined, the development trends analyzed, and the trends and underlying laws identified, all of which provides new information for Chinese wind power sustainability. It was found that Chinese sustainable socioeconomic wind power development has been growing year on year. However, the wind power ecological sustainability fell and then rose slowly, indicating that these subsystems both influence the sustainable development of wind power. [ABSTRACT FROM AUTHOR]

Bashang long-tail chickens are an indigenous breed with dual purpose in China (meat and eggs) but have low egg laying performance. To improve the low egg laying performance, a genome-wide analysis of mRNAs and long noncoding RNAs (lncRNAs) from Bashang long-tail chickens and Hy-Line brown layers was performed. A total of 16,354 mRNAs and 8691 lncRNAs were obtained from ovarian follicles. Between the breeds, 160 mRNAs and 550 lncRNAs were found to be significantly differentially expressed. Integrated network analysis suggested some differentially expressed genes were involved in ovarian follicular development through oocyte meiosis, progesterone-mediated oocyte maturation, and cell cycle. The impact of lncRNAs on cis and trans target genes, indicating some lncRNAs may play important roles in ovarian follicular development. The current results provided a catalog of chicken ovarian follicular lncRNAs and genes for further study to understand their roles in regulation of egg laying performance. • A genome-wide analysis of lncRNAs and mRNAs in chicken ovarian follicles was performed.

Motor vehicle ammonia (NH 3 ) emissions have attracted increasing attention for their potential to form secondary aerosols in urban atmospheres. However, vehicle NH 3 emission factors (EFs) remain largely unknown due to a lack of measurements. Thus, we conducted detailed measurements of NH 3 emissions from 18 Euro 2 to Euro 5 light-duty gasoline vehicles (LDGVs) in Shanghai, China. The distance- and fuel-based NH 3 EFs average 29.2 ± 24.1 mg·km -1 and 0.49 ± 0.41 g·kg -1 , respectively. The average NH 3 -to-CO 2 ratio is 0.41 ± 0.34 ppbv·ppmv -1 . The measurements reveal that NH 3 emissions from LDGVs are strongly correlated with both vehicle specific power (VSP) and the modified combustion efficiency (MCE); these relationships were used to predict LDGV NH 3 EFs via a newly developed model. The predicted LDGV NH 3 EFs under urban and highway driving cycles are 23.3 mg·km -1 and 84.5 mg·km -1 , respectively, which are consistent with field measurements. The NH 3 EF has decreased by 32% in average since the implementation of vehicle emission control policies in China five years ago. The model presented herein more accurately predicts LDGV NH 3 emissions, contributing substantially to the compilation of NH 3 emission inventories and prediction of future motor vehicle emissions in China.
