Three different excitation wavelengths （785, 633, 514 nm） are used for the same samples at the same points. All the samples show the two major Raman features of polyenic compounds assigned to double carbon-carbon （C=C） stretching vibration at approximately 1 500 cm^-1 and single carbon-carbon （C-C） stretching vibration at approximately 1 130 cm^-1 bond stretching mode. These peaks are not detected in the corresponding white parts of momo corals. However, some changes in intensities, shape, and position of C=C stretching vibrations of the same point are observed by using different excitation wavelengths. The exact position of C-C stretching vibration of polyenic molecules depends strongly on the number of double bonds contained in their polyenic chain. In addition, the number of double bonds contained in the polyenic chains shows that different colors of the red momo coral are caused by different mixtures of polyenic compounds.展开更多

This study aims to explore the demand and importance of opposing algorithmic recommendation, protecting personal privacy, and maintaining anonymity in the online environment. Methods: This study uses the dramaturgy theory to analyze the self-presentation of the momo group’s autonomous anonymous social behavior. It analyzes the motivations behind the group’s presentation, the positive effects it generates, and the media dilemmas it faces, to gain a deeper understanding of young people’s social behavior in the new media era. Results: Young people who adopt the momo identity can express their true thoughts and emotions freely in the virtual world without being limited by their real-life identities. They can also find groups of people who share their interests, values, and goals, and gain a sense of belonging and identity within the group. Conclusion: In an anonymous environment, people may be more driven by emotions rather than rational thinking, and extreme expressions become more frequent. They may also lack responsibility, potentially incubating internet social risks.展开更多
