The 7th Japan-China-Korea Joint Seminar on Atomic and Molecular Processes in Plasma (AMPP2018) Jul. 24 – 26, 2018, Hefei, China Edited by Daiji Kato, Ling Zhang, and Xiaobin Ding Abstract The 7th Japan-China-Korea Joint Seminar on Atomic and Molecular Processes in Plasma (AMPP2018) was held on July 24 – 26, 2018 at Institute of Plasma Physics in Hefei, China, as one of the activities of Post Japan-China Core University Program, JSPS-NSFC-NRF A3 Foresight Program in the field of Plasma Physics “Study on Critical Physics Issues Specific to Steady State Sustainment of High-Performance Plasmas”, and the NINS program of Promoting Research by Networking among Institutions (Grant Number 01411702). Topics of AMPP2018 cover spectroscopic properties of impurity ions in fusion plasmas, plasma-wall interactions, diagnostics of laser induced plasmas, highly charged ion physics, atomic and molecular collision dynamics, plasma simulation and diagnostics, and application of statistical methods to atomic data evaluation. In the seminar, there were 34 oral talks (including 5 talks by phD students). The total number of registered participants was 100 (89 from China, 10 from Japan, and 1 from Korea). The present issue of the proceedings has collected 12 papers from the delegates of the seminar. The present issue includes abstracts of all presentations in the seminar, the scientific program, and the list of participants. Keywords: charge transfer, Auger process, recombination, three-body fragmentation, atomic structure, oscillator strength, cross section, tungsten, lanthanide, highly charged ion, X-ray scattering, EUV spectroscopy, visible forbidden lines, hydrogen recycling, LHD, EAST tokamak, statistical analysis Preface “If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms …” (quotes from 1. Atoms in Motion, Feynman Lecture on Physics). Many characteristics of plasmas can also be understood in terms of atomic and molecular processes taking place in the plasmas. More specifically, electronic, atomic, and photonic collision processes and radiative transitions play a decisive role for atomic and molecular abundance, photon emission and absorption properties, and energy balance of plasmas. Emission and absorption line spectra of atoms and molecules give a precise measure of temperature, densities, constituent species, etc, of fusion and astronomical plasmas. It is, therefore, obvious that constant communications of researchers of atomic and molecular processes and plasma research are important for further development in applications of atomic and molecular data to plasma researches. New knowledge in atomic physics offers novel ideas to understand plasma behaviors. Collaboration with plasma researchers creates new applications and researches of atomic and molecular processes in plasmas. The seminar series of Atomic and Molecular Processes in Plasma (AMPP) has been offering a unique interdisciplinary meeting for researchers of atomic and molecular processes and plasma research in Japan, China, and Korea to discuss about these issues. The 7th Japan-China-Korea Joint Seminar on Atomic and Molecular Processes in Plasma (AMPP2018) was held on July 24 – 26, 2018 at Institute of Plasma Physics in Hefei, China, as one of the activities of Post Japan-China Core University Program, JSPS-NSFC-NRF A3 Foresight Program in the field of Plasma Physics “Study on Critical Physics Issues Specific to Steady State Sustainment of High-Performance Plasmas”, and the NINS program of Promoting Research by Networking among Institutions (Grant Number 01411702). This seminar is the extension of the last six seminars that were held in 2004 in Lanzhou, China, in 2007 in Dunhuang, China, in 2009 in Xi’an, China, in 2012 in Lanzhou, China, in 2014 in Lanzhou, China, and in 2016 in Chengdu, China. Topics of AMPP2018 cover spectroscopic properties of impurity ions in fusion plasmas, plasma-wall interactions, diagnostics of laser induced plasmas, highly charged ion physics, atomic and molecular collision dynamics, plasma simulation and diagnostics, and application of statistical methods to atomic data evaluation. In the seminar, there were 34 oral talks (including 5 talks by phD students). A poster session was also organized. The total number of registered participants was 100 (89 from China, 10 from Japan, and 1 from Korea). The present issue of the proceedings has collected 12 papers from the delegates of the seminar. The present issue includes abstracts of all presentations in the seminar, thescientific program, and the list of participants. On behalf of the organizing committee, we would like to express our sincerest thanks to all the participants who made active contributions not only in the formal presentations butalso in the fruitful discussions. We would like to acknowledge everybody who devoted veryhard work for preparing the seminar. Finally, we would like to acknowledge the administrative as well as the financialsupports from Institute of Plasma Physics, CAS and National Institute for Fusion Science.

It engages in the studies of modern Chinese literature and culture from three perspectives. First, approaching martial arts fiction as a literary subgenre, it partakes in the genre studies of martial arts fiction and through investigating major writers and their works explains how the genre was written, received, reflected, and innovated during the period in question. Second, positioning martial arts fiction as one of the most well received literary subgenre in the modern Chinese literary field, it discusses the “great divide” between “pure” and “popular” literatures and the question of how to evaluate popular literature in modern China. Through a series of textual analysis contextualized in the lineage of martial arts fiction, it offers insight into ii how the ideals of so-called “pure” and “popular” literatures were interwoven in the process of reviewing and re-creating the genre.

Virtually every part of the People’s Liberation Army (PLA) now reports to different leaders, has had its mission and Chairman Xi Remakes the PLA Xi Remakes Chairman responsibilities changed, has lost or gained subordinate units, or has undergone a major internal reorganization. Drawing on papers presented at two conferences co-organized by the U.S. National Defense University, RAND, and Taiwan’s Council REFORMS MILITARY CHINESE ASSESSING of Advanced Policy Studies, this edited volume brings together some of the world’s best experts on the Chinese military to analyze the various dimensions of the reforms in detail and assess their implications for the PLA’s ability to conduct joint operations, for the Chinese Communist Party’s control of the army, and for civil-military integration. The contributors review the drivers and strategic context under- pinning the reform effort, explore the various dimensions of PLA efforts to build a force capable of conducting joint operations, con- sider the implications for the PLA services, and examine Xi Jinping’s role in driving the reforms through and using them to strengthen control over the military.

  • The Literary Field of Twentieth-Century China Chinese Worlds
    The Literary Field of Twentieth-Century China Chinese Worlds Chinese Worlds publishes high-quality scholarship, research monographs, and source collections on Chinese history and society from 1900 into the next century. "Worlds" signals the ethnic, cultural, and political multiformity and regional diversity of China, the cycles of unity and division through which China's modern history has passed, and recent research trends toward regional studies and local issues. It also signals that Chineseness is not contained within territorial borders - overseas Chinese communities in all countries and regions are also "Chinese worlds". The editors see them as part of a political, economic, social, and cultural continuum that spans the Chinese mainland, Taiwan, Hong Kong, Macau, South-East Asia, and the world. The focus of Chinese Worlds is on modern politics and society and history. It includes both history in its broader sweep and specialist monographs on Chinese politics, anthropology, political economy, sociology, education, and the social-science aspects of culture and religions.
