Summary: Despite previous studies on tea leaf cuticular wax, little is known about the changes in component and its relation with tea flavor quality during dehydration and withering treatments in tea processing. Our study showed that tea leaf cuticular wax changed drastically and affected tea flavor formation during tea leaf development, dehydration, or withering treatment. Caffeine was identified as a major component in leaf cuticular wax, and its content increased during dehydration and withering treatments.

Summary: Squalene, a precursor of steroids with diverse bioactivities, was found in tea leaves and its content varied among different cultivars. The squalene content in tea leaves increased with leaf maturity, and the old leaves from the previous year had the highest level of squalene. The squalene levels also differed significantly among the 30 cultivars tested, with cultivar Pingyun having the highest level. The old tea leaves and pruned littering can serve as alternative sources for natural squalene extraction.

Summary: Purple-leaf tea cultivars are known for their specific chemical composition that greatly influences tea bioactivity and plant resistance. Studies have shown that the high anthocyanin and low chlorophyll content contribute to the purple-leaf phenotype, with key genes such as 4CL, ANS, UFGT, and HEME playing crucial roles in the formation of purple leaves. These findings provide insights into the mechanism of purple-leaf formation in tea cultivars.

Summary: The study reveals that NAA can promote the formation of AR in tea cuttings and has a synergistic effect with endogenous hormones. The level of the most important endogenous AR inductor, IAA, is reduced in response to NAA treatment. Comparative transcriptome analysis identifies DEGs potentially involved in NAA-mediated AR formation in tea stem cuttings. Weighted gene co-expression network analysis identifies several hub genes that may play important roles in AR formation in tea cuttings.

Summary: In this study, 46 odorants in large-leaf yellow tea (LYT) were identified, with 16 compounds newly found in LYT infusion. The key odorants with high odor activity values were identified as 2-methylbutanal, (E,E)-2,4-heptandienal, 2-methylpropanal, and 2,3-diethyl-5-methylpyrazine. The successful characterization of key aroma components in LYT beverage opens up the potential for simplifying industrial flavor optimization of the LYT product.

Summary: The recent availability of tea plant genomes has led to interest in using reverse genetics to study gene function in tea. However, the absence of an efficient transformation system has been a challenge. Virus-induced gene silencing (VIGS) could be a suitable choice for validating gene function in tea. This study used phytoene desaturase (PDS) as a reporter gene to evaluate the VIGS system and found that petiole injection was the most effective method.

Summary: A series of Ni modified Y zeolites were successfully synthesized by in-situ synthesis method, and NiMo/AxNiY catalysts were prepared. The results showed that Ni modification can affect the physical-chemical properties of the zeolites and catalysts, leading to a decrease in specific surface areas but an increase in acid sites and particle uniformity. The incorporation of Ni into Y zeolites improved the acid sites and Mo dispersion, enhancing the adsorption and hydrogenation performances of the catalysts.

Summary: This study aimed to investigate the specific role of miR-16 in granulosa cell function in PCOS. The results showed that overexpression of miR-16 or knockdown of Apelin13 could suppress granulosa cell proliferation and enhance apoptosis. Additionally, Apelin13 was identified as a potential target of miR-16. Overexpression of Apelin13 could partially reverse the effects of miR-16 overexpression on granulosa cell proliferation and apoptosis. Moreover, inhibiting Apelin13 could suppress granulosa cell proliferation and block the PI3K/Akt pathway.

Summary: The oxidation of Cu-Pb bearing alloys was studied in a temperature range of 25 to 700 degrees C. It was observed that lead could easily diffuse and form oxide films on the surface of the alloy during the oxidation process. The morphology of the oxides formed by lead at different temperatures varied. At lower temperatures, there was no significant change, while at higher temperatures, the morphology of the oxide films changed significantly, with granular lead oxide covering the alloy surface.

Summary: Existing works on impedance control of aerial vehicles are based on known translational velocity, which can be unreliable. To address this issue, a concurrent velocity observation and impedance control framework is proposed. The framework uses cost-optimized monocular vision and IMU measurements instead of GNSS modules, optical flow, and force sensors. Experimental results demonstrate the effectiveness and robustness of the proposed method in unknown environments and under vision system uncertainties.

Summary: This paper focuses on the tracking control of a class of switched nonlinear systems with prescribed performance. A barrier function and a normalized function are introduced to achieve prescribed performance control, ensuring that the tracking error stays within prescribed boundaries. Additionally, a multi-dimensional Taylor network is used to estimate the nonlinearity arising from the backstepping control process. The proposed multi-switching-based adaptive controller guarantees globally uniformly ultimately bounded signals and asymptotic tracking, while achieving global stability and independence from the initial state. The effectiveness of the proposed control method is verified through two simulations.

Summary: This study presents a simple electro-polymerization method to fabricate flexible PPy films coated on PPy nanotubes, which can be used as flexible electrodes for supercapacitors. The optimized kinetics for ion transportation result in a significantly increased mass specific capacitance of the flexible porous PPy films. The flexible porous PPy films also exhibit minimal capacitance fading after 10,000 cycles due to the large free space for volume change.

Summary: To address the issues with CNN-PCA in accurately describing and generalizing complex reservoir geological features, a 3D attention U-Net network was proposed in this study. This network does not rely on a pre-trained C3D video motion analysis model, but instead focuses on complementing the details lost in the dimension reduction process of PCA. The experimental results on a complex river channel sandstone reservoir demonstrate that the 3D attention U-Net network outperforms the CNN-PCA method in capturing the missing details and reflecting fluid flow features, leading to improved history matching results.
