An approximate method is presented in this paper for studying the dynamic buckling of double-walled carbon nanotubes (DWNTs) under step axial load. The analysis is based on the continuum mechanics model, which takes into account the van der Waals interaction between the outer and inner nanotubes. A buckling condition is derived, from which the critical buckling load and associated buckling mode can be determined. As examples, numerical results are worked out for DWNTs under fixed boundary conditions. It is shown that, due to the effect of van der Waals forces, the critical buckling load of a DWNT is enhanced when inserting an inner tube into a single-walled one. The paper indicates that the critical buckling load of DWNTs for dynamic buckling is higher than that for static buckling. The effect of the radii is also examined. In addition, some of the results are compared with the previous ones. 展开更多

We developed a shoot multiplication protocol for Syringa reticulata Blume vat. mandshurica Hara from in vitro cultured seedlings that derived from in vitro germinated seeds. The shoots could be induced on Murashige and Skoog (MS) medium with proper plant growth regulator combinations of 6-benzylaminopurine (BA) and indole-3-butyric acid (IBA). The better medium for shoot multiplication and growth was MS + 5 mg L-1 BA + 0.5 mg L-1 IBA + 20 g L-1 sucrose + 7 g L-1 agar, and the corresponding shoot induction rate was 75 %. The plantlets grew well after rooting on I/2MS medium (macro-elements of MS medium are at half-strength) sup- plemented with 1 mg L-1 IBA, and the survival percentage was 〉80 % at 16 weeks after transplanting. 展开更多

With the rapid growth of information technology,digital textbooks,as a crucial component of education digitalization,are gradually emerging as a key tool for teaching in higher education institutions.They transcend the limitations of traditional textbooks,providing a broader scope and a wealth of resources for teaching.Digital textbooks present knowledge through diverse formats,including multimedia content and interactive sessions,thereby enhancing student’s engagement and interest in learning.Furthermore,they can be updated at any time to keep abreast of the development in various disciplines and to meet the needs of the times,ensuring that students can access the latest and accurate information.In addition,digital textbooks can help promote educational equity by making quality educational resources accessible to a broader range of students.As Yang(2024)points out,integrating artificial intelligence(AI)-related courses into teaching can cultivate students’computational thinking,data analysis,and algorithmic application skills,as well as their sense of innovation and a spirit of exploration through solving practical problems.At the same time,AI technology and Big Data can be utilized to analyze students’learning data and provide customized learning paths and resources.Therefore,it is evident that digital textbooks in higher education play a vital and irreplaceable role in improving teaching quality and cultivating innovative talent.By introducing the efforts and progress made by Higher Education Press(HEP)in the development of digital textbooks and resources,as well as the specific actions and initiatives in applying AI to develop digital textbooks,strengthening copyright management and protection,and pushing forward the implementation of standards for digital textbooks,this paper discusses the current status,challenges,and future directions of developing digital textbooks in higher education. 展开更多

In recent years,deep learning methods have developed rapidly and found application in many fields,including natural language processing.In the field of aspect-level sentiment analysis,deep learning methods can also greatly improve the performance of models.However,previous studies did not take into account the relationship between user feature extraction and contextual terms.To address this issue,we use data feature extraction and deep learning combined to develop an aspect-level sentiment analysis method.To be specific,we design user comment feature extraction(UCFE)to distill salient features from users’historical comments and transform them into representative user feature vectors.Then,the aspect-sentence graph convolutional neural network(ASGCN)is used to incorporate innovative techniques for calculating adjacency matrices;meanwhile,ASGCN emphasizes capturing nuanced semantics within relationships among aspect words and syntactic dependency types.Afterward,three embedding methods are devised to embed the user feature vector into the ASGCN model.The empirical validations verify the effectiveness of these models,consistently surpassing conventional benchmarks and reaffirming the indispensable role of deep learning in advancing sentiment analysis methodologies. 展开更多

Gene Editing refers to the process of making targeted modi- fications to the genome, such as the deletion, insertion or replacement of targeted DNA sequences (Pan et al., 2011). Gene editing technologies fundamentally improve our ap- proaches to biological basic research, gene therapy, genetic improvement, etc. In the field of stem cells, gene editing can be used to modulate cell fate, such as generation of in- duced pluripotent stem cells (iPSCs) (Ding et al., 2015), cellular differentiation and transdifferentiation (Zhang et al., 2014). In gene therapy, gene editing can be used to con'ect disease mutations in patient-derived cells, which holds great promise to cure related diseases in the future (Liu et al., 2012; Liu et al., 2014). 展开更多

Advancing the rule of law in domestic and foreign-related affairs in a coordinated manner is a significant strategic measure put forward by the Communist Party of China and the Chinese government amid global changes of a magnitude not seen in a century.It is an important content of XI Jinping Thought on the Rule of Law and also a new practice facing China's highlevel opening up.To further explore and clarify the basic theory and approach of cultivating high-quality talents in the rule of law in foreign-related affairs,this article analyzes and summarizes the practice of foreign-related rule of law in the context of globalization.This is done from the perspectives of territory,normative,subject,and legal application dimensions.Key factors include the significant differences in official languages and legal cultures between jurisdictions,the closure of the legal profession admission mechanisms,and the inter-disciplinary requirements for talents praticing the rule of law in foreignrelated affairs.For this reason,the path for talent cultivation in this field in China for the new era can be explored through clarifying requirements for training and qualification,strengthening international cooperation,and building a multi-level mechanism for the cultivation and utilization of talents practicing the rule of law in foreign-related affairs. 展开更多
