This study explored the intercultural contact of a cohort of undergraduate students within the framework of the Sino-German study program at a double first-class construction university in Shanghai through an online anonymous survey. It found that these students’ intercultural contact was achieved mainly through indirect contact, among which the indirect cultural product contact and indirect interpersonal contact were the most frequent, whilst the direct oral contact and written contact were rel...

Chinese learners’ cognition and attitude towards Chinese culture are an important factor in measuring the effectiveness of cultural dissemination in China, and also an important indicator of the quality of Chinese language teaching at present. In this paper, we take Xi’an international students as our research object, and start from the channels through which they learn about Chinese culture, their knowledge of Chinese culture, and their attitudes towards Chinese culture. Through questionnaires,...

In this paper, we use partial differential equations to deal with constraint optimal control problems. We construct extremal flows by differential-algebraic equation to approximate the optimal objective value of constraint optimal control problems. We prove a convergent theorem for an approximation approach to the optimal objective value of a state-constraint optimal control problem.

Many general practices of HR are being transformed by blockchain and are being turned into efficient, progressive strategies. This paper aims to understanding how blockchain can support green and digital transformation of HR emphasizing sustainable workforce management. Blockchain strengthens the protection of information, and at the same time, makes the process more transparent and with less impact on the environment in terms of HR activities. But embracing blockchain in HRM also has its own li...

The paper conducts an in-depth exploration of the role of copyright case competitions in copyright education. It begins by analyzing the current state of copyright case competitions, then elaborates on how to construct scientifically rigorous and challenging topics for copyright case competitions, as well as how to develop fair and comprehensive evaluation criteria to enhance students’ copyright literacy. The study finds that well-designed competition topics can motivate students to thoroughly c...

Based on the requirements for teachers to educate and nurture students, and taking into account the cognitive development level of middle school students, this paper emphasizes the socialist educational perspective of moral and character development in middle school physics instruction. Using the teaching of Newton’s Second Law as an example, it explores how to cultivate ideological and political education (IPE) within this section of the curriculum. The discussion focuses on five key areas: fos...

This study presents a numerical simulation methodology for investigating blood flow in veins and arteries using a computational approach. The simulation is based on the Navier-Stokes equations, discretization techniques, and finite difference methods. The aim of this research is to provide insights into the behavior of blood flow under simplified conditions, enabling a better understanding of the underlying fluid dynamics. The methodology incorporates steady-state flow assumptions and a 2D geome...

Even though tyrosine kinase inhibitors (TKI) improve survival in non-small cell lung cancer (NSCLC), it is related to the risk of drug-induced pneumonitis. Whilst little is known regarding TKI-induced pneumonitis, adverse reactions carry a significant mortality rate and impact the available treatment options. Here, we present a case of an elderly gentleman diagnosed with metastatic ALK-positive NSCLC, who initially experienced ceritinib-induced skin vasculitis and subsequently developed acute re...

This paper examines the application of language attrition theory in reforming English writing instruction. The study begins with a review of language attrition concepts and related research, focusing on the characteristics of writing skill attrition, and proposes a comprehensive teaching reform plan. The plan includes updating curricula and content, introducing flipped classroom models, developing online learning resources and question banks, and designing group collaborative activities. Notably...

Introduction: It is complicated for regulation of growth hormone (GH) secretion. Herein, it is considered the effects of slow-wave sleep (SWS) on GH secretion and related homeostatic aging, and their implications to other complicated GH secretions. Methods: It was best and most convincing to integratively review the literatures in various fields, especially the relationship among GH, SWS, aging, evolution, etc., and then discuss and summarize to deal with such a...
