Summary: This study investigated the effects of gestational exposure to PFASs on fetal growth by examining DNA methylation in placenta tissue of pregnant women. The results showed that PFOS was negatively associated with LINE-1 methylation, and the mixture of PFASs was negatively associated with LINE-1 methylation and NR3C1 methylation. PFOA, PFNA, PFDA, and the PFASs mixture were negatively associated with head circumference. Stratified analysis by newborns' sex found that PFOA, PFNA, and the PFASs mixture were negatively associated with LINE-1 methylation in males, and LINE-1 methylation was negatively associated with ponderal index in females. Interactions between newborns' sex and PFOS/PFOA on IGF2 and LINE-1 methylation were statistically significant. These findings suggest that intrauterine exposure to PFASs affects placental DNA methylation and reduces fetal growth, which may be modified by sex.

Summary: This paper develops a realistic and generic model combining electrochemical reactions, capacity decay, and heat transfer for the design of battery thermal management system (BTMS). The multiphysics behaviors of HP-BTMS and MHP-BTMS under different working cycles are analyzed and compared. It is found that HP-BTMS and MHP-BTMS can provide good thermal management for batteries for only several working cycles. The optimized MHP-BTMS with X direction MHP, non-equidistant arrangements, and cold plates effectively controls the battery temperature even after 1250 cycles, preventing SEI formation and capacity decay.

Summary: Protonic ceramic fuel cells (PCFCs) were studied to investigate the effects of structural parameters on cogeneration performance. Increasing cell length and electrochemical reaction section (ERS) enhance the ethylene yield. The highest ethylene yield of 44% was obtained in a 10 cm PCFC at 973 K. By decreasing the ERS ratio, the current density can be enhanced up to 14% and reaches the highest value of 2235 A m(-2) in an 8 cm PCFC with a 30% ERS ratio. This model provides insights into the relationship between structural parameters and cogeneration performance in PCFC and can be applied to other hydrocarbon fuels.

Summary: Under the context of climate change, there is a call for a paradigm shift towards environmentally sensitive urban design. This study examines the impact of neighborhood layout heterogeneity on carbon emissions, considering five indicators and different renewable energy application ratios. Through multiple linear regression analysis, it is found that building density and shape heterogeneity significantly influence neighborhood carbon emissions. The heterogeneity of building height hinders carbon reduction efforts, while the heterogeneity of building shape improves carbon reduction through facade solar energy collection. However, there is a trade-off in decision-making when designing low-carbon neighborhoods due to the opposite effects of layout heterogeneity on solar energy collection and building energy consumption.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
