Ca2+ second messenger-mediated stimulation of plant marker immune gene using clinoptilolite-based Ca-alginate SCIE

Abstract :

Calcium, as an important structural, metabolic, and signalling element in plants, can stabilize cell membranes, and its physiological function can be achieved through its coordinated transport on the cell membrane. In present work, the potential of natural clinoptilolite (NCP) containing calcium alginate (abbreviated as Alg-Ca-NCP) with a Ca content of 9.46 wt% was explored, which can be used as a calcium secondary signal to stimulate plant marker immune genes WRKY33 (Tryptophan (W)-Arginine (R)-Lysine (K)-Tyrosine (Y)), NHL10 (Nicotiana tabacum L), and OXI1 (the oxidative stress-induced) under calcium resistance control conditions for approximately 3 times, 5 times and 3 times, respectively. The results verified that Alg-Ca-NCP had a significant effect on the Ca2+ transport through calcium channels. Specially, the Catalase content in leaf mustard treated with Alg-CaNCP was around 1970 U center dot g(-1)center dot min(-1) on the 21st day, much higher than that treated with CaCl2 (1365 U center dot g(-1)center dot min(-1)) and water (1210 U center dot g(-1)center dot min(-1)), obviously indicating that the Alg-Ca-NCP treatment was conducive to continuously and stably improving plant immunity. Mean-while, Alg-Ca-NCP treatment significantly affected the levels of Catalase and Chlorophyll (Chla and Chlb) in leaf, which was useful to enhance the electron transfer capacity in leaf mustard, but reduced the hypoxia-induced damage. The preliminarily investigates of the fluorescein isothiocyanate (FITC)-(Alg-Ca-NCP) expression in Arabidopsis leaves and tomato roots suggested that Alg-Ca-NCP may penetrate horizontally into the xylem ducts through the endothelial layer, and transport upwards through leaves and root cells. These results suggested that Alg-Ca-NCP may directly enter the cell membrane through transmembrane transport, but the specific mechanism still requires investigation in depth.

Quantitative estimation of earthquake effects on aquifer structure and vulnerability SCIE
期刊论文 | 2026 , 919 | TECTONOPHYSICS
Abstract & Keyword Cite

Abstract :

Earthquakes not only cause direct surface damage but also induce significant perturbations in subsurface aquifer systems. This study developed water level-barometric pressure/tide response models for three observation wells located in the Huaying Mountain Fault Zone, with the aim of quantitatively assessing the effects of the Wenchuan and Lushan earthquakes on both the structure and vulnerability of the aquifer. The results indicate that when there is a strong coherence between water level and barometric pressure/tide signals, the degree of model fitting is significantly improved, thereby enhancing the reliability of parameter inversion. Well B demonstrates greater suitability for the barometric model (BE = 0.907), while Wells A and C align more closely with tidal response characteristics. Overall, it was found that strong earthquakes lead to an increase in vertical leakage coefficients by 15 % to 50 %, whereas transmissivity decreases by 30 % to 50 %. Additionally, following these seismic events, the average fracture dip angle shifts by 15 degrees to 25 degrees, becoming more vertical; concurrently, there is a significant reduction in the aquifer vulnerability index (Cts) ranging from 20 % to 50 %. These findings suggest that earthquakes facilitate reorganization within fracture networks, enhance vertical permeability, and create new seepage channels while simultaneously diminishing pollution prevention capacity-thereby significantly elevating pollution risk. This study provides theoretical and technical support for the post-earthquake assessment of groundwater resources, as well as for the sustainable protection and targeted prevention of hydrogeological hazards.

An Approach to Inpainting Damaged Dunhuang Murals Based on Classifier-Guided Improved Diffusion Model CPCI-S
期刊论文 | 2026 , 569 , 570-586 | DATA INFORMATION IN ONLINE ENVIRONMENTS, DIONE 2024
Abstract & Keyword Cite

Abstract :

As the world's best-preserved and largest repository of cave art, the Dunhuang murals hold immense research value in aesthetics, history, and religion. However, due to the harsh geographical environment, the extensive time span of mural creation, and the impact of human activities, the murals have sustained various forms of damage. The diffusion model, a new generation of generative models, has achieved remarkable success in image inpainting. Building on the denoising diffusion probability model, this paper enhances the forward denoising method, optimizes the training process using the exponential moving average method, and proposes a Dunhuang mural inpainting technique based on a classifier-guided conditional diffusion model. This approach not only incorporates the image classification and generation principles of the conditional diffusion model but also integrates the classifier's control over the generation results. During the restoration phase, the pre-trained diffusion model is employed as a generative prior, with the backward diffusion iteration adjusted specifically for sampling the damaged areas of the murals using the given image information. Experimental results demonstrate that our method can generate semantically rich and diverse output images for various restoration scenarios. This innovation offers a novel research direction in the field of mural image inpainting.

Pioneering application of endogenous denitrification in full-scale industrial wastewater treatment plants via in-situ retrofit PubMed SCIE Scopus
期刊论文 | 2026 , 288 | WATER RESEARCH
Abstract & Keyword Cite

Abstract :

Facing increasingly stringent effluent standards and demands for operational cost reduction, retrofitting biological processes in mainstream industrial wastewater treatment plants (IWTPs) presents significant challenges. This study presents the first full-scale (13,500 m3/d) in-situ conversion of an operational Anaerobic/Anoxic/ Aerobic (AAO) system to an Anaerobic/Aerobic/Anoxic/Aerobic (AOAO) configuration at an IWTP. A novel transitional strategy was implemented to enhance internal carbon-driven denitrification. During 450 days of operation treating industrial wastewater with extremely low BOD5/N ratio (0.9 +/- 0.3), the AOAO process achieved effluent concentrations of 0.1 +/- 0.1 mg/L NH4'-N and 5.8 +/- 3.3 mg/L TN. The post-anoxic zone contributed 43.6 % to total nitrogen removal, with 43.2 % driven by endogenous carbon metabolism. The key endogenous denitrifier Defluviicoccus was enriched to a relative abundance of 1.67 %. Post-retrofit, treatment capacity increased by 29.3 % while maintaining stable operation. Optimized sludge recirculation shifted nitrogen removal hotspots, reducing recirculation energy consumption by 23.7 %. Maximized utilization of influent carbon and enhanced oxic efficiency reduced the aerobic hydraulic retention time (HRT) from 18.8 h to 6.9 h, cutting aeration energy by 51.5 % and sodium acetate dosage by 47.6 %. This study provides a practical solution for IWTPs seeking enhanced efficiency treatment and reduced operational costs.

Abstract :

纤维网格增强砂浆(textile reinforced mortars,TRM)是一种由纤维网格与砂浆组成的新型复合材料,作为纤维增强聚合物(fiber reinforced polymer,FRP)在加固领域的替代品,克服了FRP用于加固时的缺陷。TRM表现出多裂缝特征,在拉伸下具有高强度和高变形能力。为了解决不同种类纤维网格混杂以及添加钢丝网TRM拉伸性能研究不足的问题,本文通过单轴拉伸试验,研究了碳纤维网格、玻璃纤维网格、碳-玻璃纤维网格混杂以及纤维网格-钢丝网混杂增强聚合物砂浆拉伸性能的影响。试验参数包括纤维网格种类、纤维网格的配网率和不同种类网格的混杂。试验结果表明:单一碳纤维网格对TRM试件峰值强度提高显著,但对变形能力提升较差;单一玻璃纤维网格对TRM试件的峰值应变提升显著,但对峰值强度的提高幅度较低;混杂碳-玻璃纤维网格可以充分发挥碳纤维网格对峰值强度提高显著和玻璃纤维网格对峰值应变提升显著的优点;与单一碳及玻璃纤维网格比较,碳及玻璃纤维网格与钢丝网混杂,有利于提高TRM试件的变形能力,具有良好的峰后持荷能力。基于试验数据,提出了TRM抗拉强度计算公式,建立了TRM拉伸应力-应变关系式。

一种小型气浮导轨的刚度优化设计与仿真

Abstract :

气浮导轨由于摩擦极小且运动平稳,常用作精密量仪和母机的直线和回转运动基准,而本文提出在高精度主动触发式测头中内置小型气浮导轨,旨在提高测量敏感方向的导向精度、缩小测针尺寸、并减小触发测量力。由于该方法的测量精度受气浮导轨的刚度影响较大,而同时实现气浮导轨的尺寸小性化与刚度最大化又存在固有矛盾,因此本文对导轨进行了结构优化设计,从而提高导轨的刚度性能。建立了小型气浮导轨力学性能模型,利用体积有限元方法研究了多个结构参数对导轨力学性能的影响规律。结果表明:对于10 mm×8 mm的气膜,在双孔结构,浅腔直径2.6 mm、浅腔深度20 μm和孔间距4.8 mm时,导轨的转动刚度为5.28×10
