This paper uses Data fusion technology to integrate Confucian moral education with Civic Education. Different information sources are detected, and their parameter states are estimated using a weighted estimation algorithm. Principal component analysis is used to linearly transform the original information and calculate the weight values of the main feature vectors. The trust function is established using the D-S combination theory to achieve the fusion of knowledge structures. The results show that the average access rate of the teaching platform constructed based on data fusion reached 89.2% per week, and the average number of platform hits was around 716 per week. It shows that the integration of Confucian moral education ideas has enriched the content of Civic Education for college students and realized the teaching mechanism of double integration and double promotion.

Based on the data of 84 listed oil and gas companies in China from 2012 to 2021, we empirically analyzed the impact of the digital transformation level of China's oil and gas companies on the level of carbon emissions through fixed panel model and mediation effect model.The results of the study show that the development of digital transformation significantly reduces the carbon emissions of oil and gas enterprises, and that digital transformation reduces the carbon emissions of enterprises mainly by being able to influence the optimization of enterprise structure and accelerate technological innovation. There is a moderating effect in the influence of digital transformation and carbon emissions for oil and gas enterprises. These conclusions hold after robustness tests and consideration of endogeneity issues.

Herein we report a general electrochemical strategy for the Sandmeyer reaction. Using electricity as the driving force, this protocol employs a simple and inexpensive halogen source, such as NBS, CBrCl3, CH2I2, CCl4, LiCl and NaBr for the halogenation of aryl diazonium salts. In addition, we found that these electrochemical reactions could be performed using anilines as the starting material in a one-pot fashion. Furthermore, the practicality of this process was demonstrated in the multigram scale synthesis of aryl halides using highly inexpensive graphite as the electrode. A series of detailed mechanism studies have been performed, including radical clock and radical scavenger study, cyclic voltammetry analysis and in situ electron paramagnetic resonance (EPR) analysis.

As a pivotal component of rural revitalization, effective management of rural courtyard spaces is crucial for improving environmental quality and economic development. Utilizing the 2023 "Most Beautiful Courtyard" design competition in Guangze County as a backdrop, this study investigates the specific circumstances and practical challenges encountered during the courtyard transformation process. Based on a comprehensive literature review, this research establishes a unified indicator evaluation system; investigates the perspectives of villagers, designers, and managers; and conducts an in-depth analysis of the challenges faced in rural courtyard transformation practice. The goal is to offer substantial reference points for policy formulation and practical implementation, alongside recommendations for effective courtyard transformation. At the construction management level, the government should develop detailed operational guidelines for rural courtyard transformation, closely monitor construction progress, manage funds scientifically, and ensure efficient communication among the three groups. At the localization level, villagers' daily production and life should be integrated with village cultural symbols, respecting and exploring localization factors. Adequate consideration of the ecological environment and climatic conditions is crucial to promoting the sustainable development of rural courtyards. [ABSTRACT FROM AUTHOR]

Lanthanum (La) is widely used in modern industry and agriculture because of its unique physicochemical properties and is broadly exposed in the population. Some studies have shown that La may have some effects on adipogenesis, but there is a lack of related in vivo evidence. In this study, the effects of La(NO3)3 on adipogenesis and its associated mechanism were studied using C57BL/6J mouse model. The results showed that La(NO3)3 exposure caused a decrease in body weight and the percentage of fat content in mice. In addition, the adipose marker molecules and specific adipogenic transcription factors decreased in both white adipose tissue (WAT) and brown adipose tissue (BAT). Detection of signaling pathway‐related molecules revealed that canonical wnt/β‐catenin pathway‐related molecules were upregulated in both adipose tissues. In summary, in vivo exposure to La(NO3)3 might inhibited adipogenesis in mice, possibly through upregulation of the canonical Wnt/β‐catenin signaling pathway.

With the continuous development of China’s industry, the disorderly discharge and accumulation of coal gangue in mining areas have become a key ecological problem, which not only occupies a large amount of land, but also causes various pollution phenomena. Therefore, the comprehensive utilization of coal gangue has become a research hotspot in the field of environmental governance. In this paper, by mixing coal gangue and fly ash with straw in different ratios to prepare compound soil substrate and growing lettuce, the effects of different ratios of the three wastes and coal gangue particle sizes on crop growth were analyzed by measuring cotyledon area, plant height and other indexes. The experimental results showed that the best proportion of soil matrix improvement was 42.9% coal gangue, 7.1% fly ash, 10% straw and 40% soil, where the coal gangue particle size proportion was 20% fine particles, 20% medium particles and 60% coarse particles. This experiment mixed coal gangue with typical solid wastes, which will, to a certain extent, solve the problem of solid waste dumping and resource scarcity in China and provide a scientific reference for the comprehensive utilization of the three wastes and the repair of soil in mining areas.

The borylation of unreactive carbon-hydrogen bonds is a valuable method for transforming feedstock chemicals into versatile building blocks. Here, we describe a transition metal-free method for the photoredox-catalyzed borylation of unactivated C(sp3)−H bond, initiated by 1,5-hydrogen atom transfer (HAT). The remote borylation was directed by 1,5-HAT of the amidyl radical, which was generated by photocatalytic reduction of hydroxamic acid derivatives. The method accommodates substrates with primary, secondary and tertiary C(sp3)−H bonds, yielding moderate to good product yields (up to 92%) with tolerance for various functional groups. Mechanistic studies, including radical clock experiments and DFT calculations, provided detailed insight into the 1,5-HAT borylation process. Alkyl boronic esters are commonly used building blocks in organic synthesis, causing efficient C-H borylation methods to be in high demand. Here, the authors develop a method for the photoredox-catalyzed borylation of unreactive C(sp3)-H bonds, mediated by amidyl radicals to achieve C-H borylation at the λ position of carbonyl compounds.

The access of large‐scale distributed generation (DG) easily leads to energy imbalance in distribution network. To deal with this issue, this paper proposes an energy optimal schedule method for distribution network considering the participation of source‐load‐storage aggregation groups (SAGs). Firstly, the system model consisting of distribution network layer and SAGs layer is established, and the schedule objectives and constraints of each layer are also given. Secondly, considering the fluctuation on the load side, a forecasting method based on Adaboost integrated convolutional neural networks and bidirectional long‐short term memory is proposed. Then, the improved sparrow search algorithm (ISSA) is proposed by using the tent map and Levy flight on the original sparrow search algorithm. At the same time, by introducing Pareto dominance relation and adaptive grid algorithm, the multi‐objective sparrow search algorithm (MOSSA) is derived. After that, a two‐layer optimization framework (ISSA–MOSSA) is proposed to solve the studied system. The simulation results verify the accuracy of the proposed load forecasting model, the superiority of ISSA as well as MOSSA, and the effectiveness of ISSA–MOSSA in solving the energy optimal schedule problem of the distribution system with the access of DG.
