Summary: This study investigated the association between PM2.5 exposure and RNA m6A methylation as well as PTGS2 levels in peripheral blood. The results showed that increased PM2.5 exposure was associated with higher levels of global RNA m6A methylation and PTGS2. Additionally, the study found hypermethylation of PTGS2 mRNA after high concentrations of PM2.5 exposure, which coincided with increased PTGS2 expression.

Summary: This study aimed to investigate the association between PM2.5 exposure, oral microbiota, and infant growth. The results showed that PM2.5 exposure from 10th to 12th month after birth was associated with decreased linear growth of infants. PM2.5 exposure also had an impact on the oral microbiota of one-year-old infants. Specific bacteria and co-abundance groups (CAGs) related to growth were identified, and Megasphaera was found to mediate the effects of PM2.5 exposure on weight and BMI z scores of infants born within the first three months.

Summary: This study aimed to explore the potential role of miR-4301 in PM2.5 exposure-associated lung function reduction. The results showed that personal PM2.5 exposure was negatively associated with lung function and plasma miR-4301 expression. Additionally, miR-4301 partially mediated the lung function reduction associated with PM2.5 exposure, possibly through regulating the Wnt signaling pathway.

Summary: This study found that long-term exposure to PM2.5 is associated with decreased lung function and cognitive impairment. It investigated whether the effect of PM2.5 on cognitive function is mediated by lung function. The results showed that lung function partially mediates the association between long-term PM2.5 exposure and cognition. Therefore, more clean air actions should be taken to improve lung function and cognitive function in older adults.

Summary: Our study found that acute exposure to diverse dosages of PM2.5 can trigger inflammatory response and cell apoptosis, attributed to severe oxidative stress. Activation of the Nrf2-ARE pathway serves as an important compensatory process for antioxidant damage during the early stage of exposure to PM2.5. Enhancing HO-1 expression may mitigate cell apoptosis caused by PM2.5 exposure.

It was found that they inhibited the growth of microalgae but promoted pigment synthesis. Oxidative stress analysis showed that PS and A-PS caused oxidative damage to algal cells. Metabolomics analysis showed that PS and A-PS significantly increased different metabolites.

Summary: Pendulum impact testing and numerical analysis were conducted for the first time on civil air defense walls sprayed with 2-mm polyisocyanate-oxazodone (POZD) coatings at different positions, in order to prevent serious casualties and secondary injuries caused by high-speed splashing concrete fragments. The results showed that spraying a 2-mm POZD coating can significantly reduce damage, restrain splashing of fragments, ensure wall integrity, and improve impact resistance and airtightness. Additionally, using large-rupture-strain fiber-reinforced polymer (FRP) on the back improved bending stiffness and deformation capacity, reducing residual displacement. The failure modes and characteristics obtained from this study provide evaluation criteria for existing civil air defense walls.

Summary: This study investigates the performance of T-joints in the jacket foundation of offshore wind turbines under impact loading by means of experimental and simulation analysis. The deformation pattern and dynamic response of one hollow T-joint and eight concrete-filled double steel tubular T-joints (CFDST T-joints) are explored through a pendulum testing machine. The experimental results indicate that the local indentation dominates in the deformation process of hollow T-joint while the failure mode of CFDST T-joint will be commonly the global bending. The impact force-displacement curves corresponding to different parameters have similar tendencies and each curve can be divided into four stages. Increasing the impact velocity and axial compression ratio can reduce impact resistance. Meanwhile, increasing outer tube thickness and changing hollow rate exert a remarkable effect on the dynamic performance. Finite element models are then proposed to validate the experimental results and investigate the energy dissipation mechanism of T-joints under impact loading. The plastic deformation of the outer tube is the main energy dissipation mechanism for CFDST T-joints. In general, the investigation in this study offers a reliable basis for the study of impact failure mechanism for CFDST T-joint.

Summary: This paper focuses on the dynamical behavior and modulation instability of optical solitons in nonlinear directional couplers. The expressions of single soliton solutions are derived, and the hyperbolic secant-type pulse is used to excite the input channel. The dynamical behavior of single optical soliton in traditional directional and negative index material couplers with varying self-phase modulation is discussed. Based on linear stability analysis, the distribution of modulation instability gain is studied, and the effect of dispersion, nonlinearity, and input power on modulation instability gain is investigated. It is worth noting that the physical information neural network algorithm performs well in simulating the transmission of an optical pulse in the coupler and leading to novel optical waves. These results contribute to understanding the generation of soliton-like excitation and lay a foundation for exploring novel optical solitons in nonlinear directional couplers.

Summary: This study investigates the effect of impact force and axial force on the dynamic response of CFDST-K joints in offshore wind turbine (OWT) applications. Experimental and numerical methods are used to analyze the deformation property and dynamic response of the joints. The results show that increasing impact energy leads to higher impact force, displacement, and plastic strain. Improving the axial compression ratio and flexural stiffness enhances the deformation and impact performance of the joints.

Summary: Ice loading is the main design load for offshore platforms in Bohai Bay. The ice-induced vibration of the platform was studied, and two different designs with concrete filled double-skin legs were tested. The results showed that both platform designs reduced the ice-induced vibration, with the self-centering design having a better control effect. The use of concrete filled double-skin legs improved the structural stiffness and the addition of prestressed tendons further improved the platform's performance.

Summary: Localized surface plasmon resonance (LSPR)-based sensors have great potential in medical diagnosis, food safety regulation, and environmental monitoring. This paper presents an improved plasmonic sensor based on Fano resonances between LSPR and the Rayleigh anomaly (RA), which allows for the formation of narrowband reflection peaks within the LSPR-based broadband extinction window. By carefully adjusting the angles of incident light, the sensor can be optimized for detecting local refractive index changes caused by the bonding of target molecules on the surface of the nano-device. The hybrid sensor demonstrates significantly higher figure of merit (FOM) compared to traditional RA- and LSPR-based sensors.
