Conversations with ChatGPT can shed light on Dialogue of Civilizations in the age of AI. Method/process Currently, GPT-3.5 offers users 30 free query credits per day. By creating an outline for the conversation, Chen Yu engaged in a dialog with ChatGPT on various issues of Dialogue of Civilizations. Result/conclusion Today, the Standard of Civilization has long been abandoned, and the Clash of Civilizations has been widely criticized. In the era of AI, the AI technology represented by ChatGPT can help promote the Dialogue of Civilizations, help realize real-time communication between people of different cultural backgrounds, enhance the understanding and appreciation of different civilizations, and identify and alleviate prejudices in the dialogue of civilizations. At the same time, the AI technology represented by ChatGPT can also help promote Dialogue within Civilizations and play a positive role in resolving civil conflicts, promoting the integration of immigrants, protecting the voices of vulnerable groups, giving full play to the unique value of women, and building an age-friendly society. However, AI technologies must be developed and used with caution and with due regard to ethical considerations, in particular to prevent AI algorithms from perpetuating prejudices and reinforcing existing inequalities.",

				"extra": "publicationTitle: 原子核物理评论\noriginal-title: Study on the painting injection methods for the high intensity proton synchrotron\noriginal-abstract: The space charge effect is the core problem of high intensity proton accelerator, especially at injection and initial acceleration stages. Using the phase space painting with optimized process, will effectively eliminate the influence of space charge effect on injection and acceleration efficiency, and emittance increase. Transverse phase space painting methods can be divided into correlated painting and anti-correlated painting. In this paper, firstly, the transverse phase space paintings for the high intensity proton synchrotron are discussed in detail, including different painting methods and different implementation methods. Secondly, based on the injection system of the China Spallation Neutron Source, the beam injection process and anti-correlated painting design scheme are studied in detail. The reasons for the reduction of the actual vertical painting range and the influence of edge focusing effects of the bump magnets on the painting and beam dynamics are deeply explored. In addition, the method to perform the correlated painting based on the mechanical structure of the anti-correlated painting scheme and its key role in realizing the CSNS design goal are briefly introduced. Finally, according to the requirement of switching between different painting methods online in future accelerators, a new injection scheme that can realize correlated and anti-correlated painting simultaneously has been proposed. The new painting injection scheme has been demonstrated, simulated and optimized in detail.",
