Liu Mingrui and Zhao Bichen : Practitioners of Neidan in Modern Beijing
No full textRegarding practitioners of neidan 内丹 (internal alchemy) Liu Mingrui 劉名瑞 and Zhao Bichen 趙避塵, who were active in the Beijing area from late-Qing through early Republican times, l have examined their backgrounds and their neidan practice, in considering the manner neidan was practiced during the period. Liu Mingrui was from Wanping county 宛平縣 in Beijing. In middle age, he became devoted to Daoism, and studied under a mentor from the Nanwu school 南無派 of the Quanzhenjiao 全眞教, and he is found in their lineage as the twentieth head of the Nanwu school. He lived at Qianfengshan 千峰山 and Taoyuanguan 桃園觀 in Changping county 昌平縣 to the northwest of Beijing, and had several disciples. He authored three works, the Daoyuanjingweige 道源精微歌, the Qiaojiaodongzha 敲驕洞章 and the -yikao- 易考, all of which were concerned with neidan practice. In his works, he often had high praise for the works of Wu Chongxu 伍沖虛 (Wu Shouyang 伍守陽) and Liu Huayang 柳華陽, known as the Wu-Liu school 伍柳派, and, when his neidan practice is examined, primarily in the Daoyuanjingweige, one sees that it duplicates exactly that advocated by the Wu-Liu school. Zhao Bichen was from Changping county in Beijing. In his youth he became a student of Liu Mingrui, and began his study of neidan practice. Thereafter he visited famous neidan practitioners in various locations, meeting Liao Ran 了然 and Liao Kong 了空 of the Longmen school 龍門派 at Zhenjiang 鎭江, and then becoming the eleventh head of the Longmen school. Thereafter, while operating a shop on the northern outskirts of Beijing, he spent his life in spiritual training and conversion of disciples. When the content of his Xingmingfajuemingzh 性命法訣明指 is examined, it is clear that on many points he was at odds with the works of the Wu-Liu school, which was representative of the Longmen school. Moreover, in his later years he converted many disciples to Daoism, but the main location were the facilities of the popular religion Zailijiao 在理教, and not Daoist temples. Judging from the above--the facts that while Liu Mingrui was an adept of neidan practice of Nanwu school of the Quanzhenjiao, he expounded the neidan practice of the Longmen school, and that Zhao Bichen expounded neidan practice and saw himself as the eleventh head of the Longmen school, although he was a lay person and not entirely faithfulto the Longmen texts, the popularity of the neidan practice of the Wu-Liu school, and the relationship to the Zailijiao-- I conclude that by considering these two men, one sees a direct indication of the concrete conditions of neidan, which was intermixed with various elements at the time
Physics informed neural networks for solving inverse thermal wave coupled boundary-value problems
Full text linkAs one of the essential parameters in thermophysical analysis, effective measurement of thermal diffusivity is necessary. This paper utilizes the Physics-Informed Neural Networks (PINN) framework to simulate the diffusion of thermal waves. The governing equations / boundary-value problem (BVP) for the thermal waves are expressed in a coupled partial differential form, derived using the method of separation of variables. The inverse problem associated with the coupled partial differential equations is solved using a dimensionless equation / BVP with a loss function that incorporates physical information. Even in the presence of experimental system errors, the neural network (NN) method introduced in this work (“new NN method”) was shown to be capable of robustly solving the thermal wave inverse problem without nonlinear DC components at different spatial locations, for determining the unknown thermal diffusivity of green (unsintered) metal powder compact materials. The results indicate that the coupled partial differential equations for the amplitude and phase of thermal waves within the PINN framework represent a promising strategy for determining thermophysical parameters
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
