Aimed to adapt the experimental teaching to keeping up with the actual application of the experimental scene, an experimental teaching based on virtual-real combination for mobile communication was proposed in this article, which realized the collaborative mode of combining online virtual operations and real operations. The virtual experiments were complementary to real experiment operation and on-the-spot experience through sharing virtual software, instruments and equipment and remote equipment control with automatic logging for experimenter's data contained knowledge learning, experimental operation process and experimental results so as to evaluate the experiment. Compared with regular sessions, the degree of curriculum achievement in experimental class has improved significantly and the distribution of scores was more reasonable according to tracking the whole process of students. The system with virtual-real combination enriches the practical strategies and improves the quality of mobile communication experiment studying effectively.

Financial technology (FinTech) is transforming the financial services industry by offering innovative, convenient solutions for businesses and individuals. This study examines the factors influencing FinTech adoption, with a special focus on trust. By integrating insights from both the unified theory of acceptance and use of technology (UTAUT2), and the trust theoretic model (TTM), this research uncovers critical determinants of FinTech adoption. Utilizing survey responses obtained from 399 participants, this research employs the partial least squares structural equation modelling method. The findings reveal that performance expectancy, effort expectancy, social influence, habit, price value, and facilitating conditions significantly influence users' intentions to use FinTech services. In addition, the study shows that trust plays a crucial role in FinTech use, as it influences both the intentions to use and the actual use of FinTech. Surprisingly, hedonic motivation was found not to affect users' intentions, implying that people see FinTech as a practical, rather than enjoyable, endeavor. These insights provide valuable guidance for service providers and policymakers seeking to enhance FinTech adoption and utilization while ensuring the security and trustworthiness of these digital platforms.

The natural frequency and life of the compressor blades of the aero-engine were obtained by the modal and high cycle fatigue (HCF) experiment. Two failure criteria of compressor blades: vibratory stress and fatigue crack growth were investigated through theoretical and simulation techniques. The study found that resonant generates a non-proportional loads history output in the different regions of the compressor blade in the HCF test. The predictions of the crack growth path are compared with the experiment results. The sensitivity of vibratory stress and resonant frequency to crack locations and lengths are researched. The distribution characteristics of stress and crack should be fully understood before to make a more accurate fracture failure analysis and life predictions are verified. [ABSTRACT FROM AUTHOR]
