The Tianqin, often a plucked zither or lute, holds significant cultural and musical heritage in China. The objective of this study is to explore the evolutionary perspectives on the culture of a Chinese folk musical instrument by examining its playing techniques and cultural changes. Conducted in Longzhou County, Guangxi Zhuang Autonomous Region, China, this study involved ethnographic fieldwork, including participant observation and interviews with key informants such as Tianqin musicians and craftsmen. Data analysis was performed using thematic analysis, revealing that (...) the Tianqin has transitioned from a ritualistic instrument to a symbol of cultural heritage and mass entertainment. The findings highlight the instrument's adaptability through innovations in playing techniques and materials, supported by governmental initiatives promoting Tianqin culture. This research underscores the importance of preserving and promoting traditional musical instruments in contemporary society. The study's insights contribute to a broader understanding of cultural adaptation and innovation in ethnomusicology. (shrink)

Research on Sino-Japanese Relations is an important part of the field of Japanese Studies in China. This article offers an overview of research on Sino-Japanese relations over 60 years of PRC history. It focuses on research since the end of the Cold War, and especially on progress in the field since the beginning of the twenty-first century. On the basis of this overview, the author discusses gaps in the literature and directions for future research. The author would also like to (...) express in advance his regret that due to limited space it is not possible to mention every piece of important scholarship in the field. (shrink)

This paper studies the state of charge estimation of supercapacitors and lithium batteries in the hybrid energy storage system of electric vehicles. According to the energy storage principle of the electric vehicle composite energy storage system, the circuit models of supercapacitors and lithium batteries were established, respectively, and the model parameters were identified online using the recursive least square method and Kalman filtering algorithm. Then, the online estimation of SOC was completed based on the Kalman filtering algorithm and unscented Kalman (...) filtering algorithm. Finally, the experimental platform for SOC estimation was built and Matlab was used for calculation and analysis. The experimental results showed that the SOC estimation results reached a high accuracy, and the variation range of estimation error was [−0.94%, 0.34%]. For lithium batteries, the recursive least square method is combined with the 2RC model to obtain the optimal result, and the estimation error is within the range of [−1.16%, 0.85%] in the case of comprehensive weighing accuracy and calculation amount. Moreover, the system has excellent robustness and high reliability. (shrink)

This paper contains four variations on Duhem's theme about the contrast between the abstract French mind and the concrete British mind. The first variation brings out the real contrast between two types of methods and their results: the A method or models and the C method or models. The second variation gives a critical discussion of the Callender-Cohen deflationary contruel of scientific representation. The third variation discusses Russell's structuralism in connection to the theme. And the fourth variation critically discusses the (...) relationship between models and fiction in connection to the distinction between the A-models and the C-models. A coda maps out without sufficiently detailed arguments the author's view on the nature of the C-models and why they, and only they, can be viewed as fully fictional. (shrink)
