Opportunistic energy trading between co-located energy-harvesting wireless sensor networks
No full textWireless sensor networks are increasingly using energy harvesting to extend their lifetime and avoid battery replacement. However, ambient energy sources typically exhibit temporal-spatial variation, and complex power management algorithms have been proposed to model and adapt to variation and achieve energy-neutral operation. However, existing algorithms are limited in the scale of spatial variation that they can accommodate, as they are restricted by the physical boundaries of the network. This paper proposes Opportunistic Energy Trading (OET) to overcome this limitation, and allow networks to trade energy to neighbouring networks which may either be heavily energy-constrained or else suffering from a temporary drought of harvested-energy. To show the potential of OET, we present a case study consisting of an energy-constrained battery-powered WSN which neighbours an energy-harvesting WSN. The case study considers a simplified version of OET, whereby the harvesting WSN transfers (i.e. trades for free) its excess energy to the constrained WSN in order to extend its lifetime. The case study is evaluated through simulation, and shows that the lifetime of the energy-constrained network increases by 40% while the effects on the harvesting network can be considered insignificant

Inventing A Wolfish China - On Jiang Rong'S Wolf Totem
No full textThe Wolf Totem by Jiang Rong has won great success both in and out of China. Jiang Rong criticizes Han Chinese and embraces the culture of the northern ethnic minority group, the Mongols, because of its stronger sense of competition and domination. In the epilogue of this novel, Jiang argues that the wolf totem was the most ancient totem for all Chinese people and retells Chinese history using this framework. This paper explores the background of the novel and its author, as well as supporting materials the author uses in his proposal concerning the wolf totem, and suggests that the wolf totem is a purely ideological invention of Jiang Rong. This invention reflects Jiang's own philosophy and caters to the cultural needs of modern Chinese people. In inventing the wolf totem, the author uses historical documents, archeological findings, as well as a far-fetched bodily metaphor. However, none of this evidence is validated by scholarly research
Interviews with Yang Jiang
No full textYang Jiang was born, under her real name of Yang Jikang, in 1911. She is the author of a novel, several plays, and a large number of sanwen. Her first writing dates back to 1933, and her latest work, Women sa (We Three), in which she recalls family memories, appeared in July 2003, and has been highly successful, with 180,000 copies sold within two months. However, for thirty years, from 1949 to 1981, for obvious reasons, Yang Jiang preferred to devote herself entirely to teaching, research—she is also an expert on Chinese and foreign literature—, and translation: she is the translator, most notably, of the Chinese version of Don Quixote. She is now devoting herself to the publication of the work of her husband, the scholar Qian Zhongshu (1910-1998). In France she is best known for her narratives of the Cultural Revolution, published by Christian Bourgois.The two interviews that follow were carried out in 2005. Yang Jiang gave written answers to the questions I had sent her, which explains the slightly abrupt nature of our exchanges, given that it was not possible for me, by the nature of the interviews, to respond spontaneously to her words. If we seem to jump from one subject to another, it is because I had asked her to clarify certain details that I planned to use in my research into her work (« La Figure de l’intellectuel chez Yang Jiang » [“The Intellectual in The Work of Yang Jiang”], which became my doctoral thesis in Chinese Studies, under the direction of Isabelle Rabut, Inalco, Paris, December 2005, 404 pp.). Yet, to me, these words of Yang Jiang are of interest just as they are, since she uses words so sparingly and generally refuses to do interviews. In any case, and I am grateful to her for this, she only allowed these words to be published precisely because she had written them herself
Bioinspired preparation of polydopamin microcapsule for multienzyme system construction
No full textInspired by the structural organization of mitochondria and the bioadhesive principle, a simple and versatile approach to construct a multienzyme system is developed. More specifically, the multienzyme system is composed of a polydopamine (PDA) microcapsule scaffold and three spatially separated enzymes. The PDA microcapsules are prepared through the rapid, spontaneous self-polymerization of dopamine on the surface of CaCO3 microparticle template, followed by dissolution of the template using EDTA. The wall thickness of the microcapsules can be tuned by the dopamine concentration in an aqueous solution. The three enzymes are respectively immobilized through physical encapsulation in the lumen, in situ entrapment within the wall and chemical attachment on the out surface under extremely mild conditions. As an example, a multienzyme system, containing α-amylase, β-amylase and glucosidase, was constructed to convert starch into isomaltooligosaccharide, and the multienzyme system displays higher catalytic activity and enhanced operational stability. The method developed in this study will establish a powerful platform for the facile construction of multienzyme cascade systems. © 2011 The Royal Society of Chemistry.Lei Zhang, Jiafu Shi, Zhongyi Jiang, Yanjun Jiang, Shizhang Qiao, Jian Li, Rui Wang, Ruijie Meng, Yuanyuan Zhu and Yang Zhen
Jiang Rong, Le Totem du loup, (Wolf Totem) translated by Yan Hansheng and Lisa Carducci
No full textPublished in China in 2004 by Changjiang wenyi chubanshe, Jiang Rong’s novel Lang tuteng (Wolf Totem) was immediately a phenomenal success. I myself witnessed this success while in China, where bookshops displayed multiple stacks of the book. Its author, Jiang Rong, the pseudonym of Lu Jiamin, was an activist in the Tiananmen Square movement in 1989; now a researcher in social sciences and the husband of Zhang Kangkang, a well-known writer, Jiang Rong maintained a mystery surrounding his iden..

Jiang Jieshi : from fascination to disappointment of the bolshevik revolution
No full textThis article is dedicated to Jiang Jieshi's - one of the greatest leaders of 20th century China - attitude to the Bolshevik Revolution. After introduction the author outlines the May Fourth Movement, where it explains the reasons of rejection of the traditional culture by the Chinese intellectuals and their interest in the Russian Revolution. The main part of the article focuses on the reasons of Jiang Jieshi's fascination of the revolution's phenomenon, and on the explanation of his disappointment of the Bolshevik Revolution and the Soviet Russia for which his mission to Moscow in 1923 had played a crucial role

Zoobank.org/ urn:lsid:zoobank.org:act: 0E8C0D6B-E580-43DE-990F-5DC4A26695DC (Figures 97–100, 219–222, 295–296, 333, 346, 358, 389, 425, 453, 480) Material examined. Holotype, male, CHINA: Xinjiang: Tulufan, (20–140 m), 24-VI-1958, leg Guang Wang (IOZCAS). Paratypes, same data as holotype (2 IOZCAS); Jiashi (1160 m), 20-VI-1959, leg Afu Tian (1 IOZCAS); Hejing, 26-VII-1958, leg Changqing Li (1 IOZCAS). Diagnostic description. Length 1.90–2.50 mm (Fig. 97–100). Vestiture on dorsum grayish unicolorous. Rostrum (Fig. 219–222) moderately long, poorly sexually dimorphic, slightly longer in female than in male (Rl/Rw 5.30–5.50 in male, 7.00– 7.50 in female; Rl/Pl 0.88–0.92 in male, 0.93–0.94 in female), thin, in lateral view curved at base, then almost straight to apex. Pronotum (Pw/Pl 1.10–1.17) with slightly rounded sides from base to apex, slightly wider than long. Elytra suboval (Ew/Pw 1.26–1.36; El/Ew 1.50–1.69), with slightly rounded sides in basal half. Femora (Fig. 295–296) unarmed, tibiae (Fig. 333) without sexual characters. Third tarsomere moderately wider than second tarsomere (Fig. 346). Claws (Fig. 358) with small medial teeth as long as 1/3 of claw, separated from claw from base. Male genitalia: body of penis (Fig. 389) in dorsal view moderately large, parallel-sided near to apex, with acutely pointed apex (Fig. 425), in lateral view strongly curved and very subtle, nearly as long as apodeme. Female genitalia: spermatheca see Fig. 453; spiculum ventrale (Fig. 480) with thin arms spaced in basal third but distinctly narrowing to middle, then completely joined to apex. Remarks and comparative notes. This species is closely related to T. tachengicus and T. sulphureus. Tychius zhangi differs by the rostrum of both sexes being longer and that of the female in lateral view of the same width from the antennal insertion to the apex and not distinctly narrowed. The medial teeth of the claw are distinctly smaller and shorter than in the other two species. Finally, the body of the penis in dorsal view is moderately large, parallelsided near to apex, with acutely pointed apex, in lateral view strongly curved and very subtle, nearly as long as an apodeme.
