Aiming at the problems of poor adaptability and low secret key generation rate of secret key generation scheme based on single characteristic parameter of wireless channel, a secret key generation method based on joint characteristic parameters of amplitude and phase of wireless channel is proposed. This method is based on the single-eavesdropping wireless fading channel model; the joint characteristic model of amplitude and phase of wireless fading channel is established; it detects and extracts the joint characteristic parameters of amplitude and phase of channel, and then the proposed characteristics are quantified by using the equal probability joint quantization strategy of amplitude and phase to generate the secret key random parameters. In this paper, the amplitude and phase joint feature parameter detection method of wireless channel can not only improve the generation rate of random secret key parameters but also make the eavesdropping party’s eavesdropping error rate closer to 0.5. The test results show that the proposed scheme can significantly improve the rate, reliability, and security of generating key random parameters.

In the 1990s, China created a research evaluation system based on publications indexed in the Science Citation Index (SCI) and on the Journal Impact Factor. Such system helped the country become the largest contributor to the scientific literature and increased the position of Chinese universities in international rankings. Although the system had been criticized by many because of its adverse effects, the policy reform for research evaluation crawled until the breakout of the COVID-19 pandemic, which accidently accelerates the process of policy reform. This paper highlights the background and principles of this reform, provides evidence of its effects, and discusses the implications for global science.

In this article, the author uses a narrative-semiotic approach to discuss the Eight Revolutionary Model Plays of China's Cultural Revolution, which left profound but sometimes negative influences on the lives of Chinese people. Because of the political upheavals of the time, the Eight Revolutionary Model Plays dominated the cultural stage during this special period of Chinese history. However, they have become popular again in recent years — an interesting cultural phenomenon that deserves academic observation Phelan's three narrative voices (mimetic, thematic, and synthetic) are used for narrative analysis and it is determined that these model plays primarily use the thematic voice. Jakobson's semiotic theory of six factors within the speech event is used for semiotic analysis and the result is that each of the six factors has polyphonic features. The conclusion is that although the plays were originally made for political purposes, with time as well as people's appreciation and consumption they have become part of Chinese culture. In this sense, one can say that art, like language, is also a kind of convention.

Liu Shipei received an outstanding classical education and obtained the juren degree in 1902. After failing the metropolitan exam in the following year, however, he went to Shanghai where he became involved in revolutionary activities and wrote a number of political, ethical, and historical treatises, including the Textbook on Ethics. In his Textbook, Liu sets out a more systematic presentation of an ethical theory than any we find in earlier centuries. His goal is a complete reworking of Confucian ethics, and his methods and conclusions merit comparison to the similar objectives of Liang Qichao in the more popularized On the New People of three years earlier. Like Liang's "new ethics," Liu's ethical theory is shorn of much of the metaphysical apparatus that accompanied earlier neo-Confucian ethical teachings, and, like Liang, Liu is to some extent familiar with Western philosophical trends and concepts. Finally, like Liang, Liu finds "rights" to be centrally important to his new ethics, as the following chapters from the Textbook make clear

PurposeThis study aims to examine the mediating role recovery plays in the relationship between resilience and posttraumatic growth among breast cancer patients.MethodsA cross-sectional study design was implemented between January 02, 2021 and April 29, 2021. A total of 789 breast cancer patients from eight hospitals in Liaoning province were selected for participation in this study. These participants completed questionnaires, which included the Post-Traumatic Growth Inventory, EGO Resilience Scale and the Questionnaire about the Process of Recovery. The associated factors of PTG were analyzed using hierarchical multiple regression. The proposed relationships among resilience, recovery, and PTG were checked by structural equation modeling analyses.ResultsThe average PTG score of breast cancer patients was 53.00 ± 28.30. PTG was positively correlated with both recovery and PTG.ConclusionBreast cancer patients were found to exhibit a moderate degree of PTG. Resilience was positively associated with PTG and recovery mediated the positive effect of resilience on PTG. Resilience might serve as a crucial protective factor that could explain positive growth in life-threatening illnesses through the mediating path of recovery.
