Abstract The integration of visual communication art design and traditional culture in the era of new media is an important way to promote and inherit excellent traditional Chinese culture. It can create a strong traditional cultural atmosphere in society and has important significance for cultural and humanistic development. In addition, the way people obtain information has changed in the era of new media, so the integration of traditional culture in visual communication art and design has a more profound impact, which is of great significance for the overall social and cultural development and the creation of a strong cultural atmosphere. Therefore, in the era of new media, visual communication art design should focus on the integration with traditional culture.

Abstract Innovations in new material technologies and the development of the new materials industry hinge on robust talent support. In China, the structural imbalance in the supply and demand of talent in this field has become prominent. The gap between talent supply and demand continues to widen in terms of quantity. Also, there is a relative lack of specialized technical talent in terms of quality. Regionally and age-wise, the distribution of talent remains suboptimal. The primary reasons for this imbalance in China’s new materials talent structure are twofold. From the supply side, the training system for new materials talent lags behind industrial development needs. From the demand side, the new materials industry faces challenges, including low salary levels, employment perceptions, and recruitment mechanisms. It’s recommended to foster an environment conducive to the growth of new materials talent, establish a multi-tiered talent training system, accelerate the deep integration of industry, academia, and research, optimize the talent development ecosystem in the new materials industry, and expedite the establishment of high concentrations of new materials talent

Abstract Public funded normal university students are an important force in education, and their English learning quality and ability are directly related to the quality of future education and teaching work. However, due to various reasons, public funded normal college students often have anxiety in English learning, which has a certain impact on their learning and development. Through literature review and investigation and analysis, this paper finds that the anxiety of publicly-funded normal students in English learning mainly comes from the learning environment, learning methods and personal psychology, etc. Bad learning environment, improper learning methods, personal psychological pressure and lack of self-confidence may lead to the anxiety of publicly-funded normal students. To solve the above problems, this study puts forward the corresponding countermeasures, including establishing a positive learning environment, providing effective learning methods and psychological counseling and support. In this way, it can help the public funded normal students to overcome anxiety, improve their English learning ability and self-confidence, so as to better devote themselves to education.

Abstract For a long time, the libraries in the same region have been divided into their own, which has seriously wasted social resources. Libraries, which originally had advantages, have not been able to develop in accordance with the established ideal model, often unable to meet the needs of readers due to the shortage of funds and other problems. At the same time, the harmonious coexistence of ecological culture and library culture has been ignored. From the perspective of ecosystem, the ecological niche of public libraries is convergent, and the role of ecological education is still limited. The construction of hardware facilities and equipment lacks of ecological elements, and a new cultural ecosystem formed by the library from the ecological perspective and its unique development mode are bound to contribute to the library cause. Therefore, this paper aims to combine the new deployment made by the central and provincial economic work conferences to further promote the construction of ecological civilization, focus on the actual situation of Changde, and explore the construction and optimization countermeasures of public libraries in Changde based on ecological theory, information ecology theory and high-quality development theory, so as to promote the high-quality development of public cultural services in Changde.

Abstract Pi Sigma neural network is a kind of high-order feedforward neural network, which is characterized by fast convergence speed and strong nonlinear mapping ability. However, for the growing large dataset, the traditional Pi Sigma neural network suffers from the problems of complex network structure, difficulty in determining weights, and low learning efficiency. Therefore, this paper proposes a hybrid heuristic algorithm that combines the flower pollination algorithm with the firefly algorithm to optimize the weights and biases of the Pi Sigma neural network. The experimental results show that the optimized neural network has good performance in many aspects.

Abstract This paper explores the issue of identifying rainbow embeddings within random graphs, which occur when all the edges of a subgraph are colored distinctly. Using probabilistic methods, we investigate the conditions under which a random graph contains such an embedding. Specifically, for a specified graph H, when p is greater than the threshold, randomly select a color from the set of colors c to color the edges of graph G, then with high probability graph G contains a rainbow copy of H. These results provide new insights into the interplay between random graph theory and edge coloring, with potential applications in areas such as network design and combinatorics.

Abstract The development of the digital service industry not only fosters new forms of digital industries and creates new drivers for economic growth but also serves as a crucial engine for green and low-carbon urban transformation, offering innovative pathways to improve urban energy efficiency. Using matched data from 280 prefecture-level cities in China, this study empirically examines the relationship between digital service industry agglomeration and urban energy efficiency. The findings reveal that digital service industry agglomeration significantly enhances urban energy efficiency, and this result remains robust even after a series of tests, including the use of instrumental variable methods. Mechanism analysis indicates that both formal and informal environmental regulations play a significant positive moderating role in this process. Furthermore, heterogeneity analysis shows that the impact of digital service industry agglomeration on urban energy efficiency is more pronounced in key cities (provincial capitals and municipalities), non-resource-based cities, and cities located on the southeastern side of the Hu Line. The study concludes that leveraging the energy efficiency gains from digital service industry agglomeration is of great importance for promoting a synergistic transition to digitalization and greening, and for advancing carbon peak and carbon neutrality in a prudent and proactive manner.
