From Han tradition to Tang elegance
No full textThis long paper is the comprehensive essay to the exhibition China at the court of the emperors. Unknown masterpieces from Han Tradition to Tang elegance (25-907), held at Palazzo Strozzi, Florence, in Spring 2008.
It thoroughly explains the development of the arts in China from the Han to the Tang dynasties against the historical and cultural context of the time, underlying the new perspective recently put forward on the basis of the latest archaeological excavations. These have driven scholars to regard the period of division between Han and Tang no longer as a ‘dark’ epoch of unrest, during which the country was politically and culturally fragmented, but instead as a moment of regeneration and flowering of the arts, stimulated by intercultural exchanges with Rome, Persia, India and Central Asia. From this new viewpoint, it appears clear that the great renaissance of the seventh to eighth centuries was the culmination of a long process that had germinated in the second to third centuries
On Tang Junyi’s Critique of Anselm’s Argument for the Existence of God
No full textAnselm’s argument for the existence of God posits that the concept of God inherently implies its existence. Tang Junyi critiques this argument from two fundamental angles. Firstly, he argues that the contingency of human thought places an unwarranted burden of proof on the existence of God, introducing an inherent contradiction within the argument’s premise. Secondly, he contends that Anselm’s argument fails to deduce the existence of God from empirical things. Tang’s empirical approach to critiquing the argument bears a superficial resemblance to St. Thomas Aquinas’s cosmological argument for God’s existence, yet a profound difference exists between the two, precluding their equivalence. Delving deeper, Tang’s critique is rooted in the Confucian philosophy. Nevertheless, Tang’s critique, while insightful, does not fully dismantle Anselm’s argument, underscoring the intrinsic differences and tensions between Chinese and Western perspectives on religion and philosophy

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
The astrochemical observatory: Computational and theoretical focus on molecular chirality changing torsions around O – O and S – S bonds
No full textThe observation of hydrogen peroxide in the interstellar medium represents a remarkable discovery for the astrochemistry community. The prototypical role that this molecule, arguably the simplest chiral molecule, plays in the evolution of life in biospheres, is related to the chirality change transitions associated with the torsional motions around the O - O and the S - S bonds. In this paper, we present an overview on the state-of-art of possible experiments to demonstrate chiral effects discrimination and computational tools applied to peroxides and persulfides
Stenus fuscus Hu & Tang 2018, sp. n.
No full textStenus fuscus Hu & Tang, sp. n. (Figs. 3, 17–22) Type Material. Holotype: China: Sichuan: ♂, glued on a card with labels as follows: “ China: Sichuan Prov., Mianning County, Yele Daba, 28°55'22''N, 102°13'32''E, 2500m, 25.VII.2015, Jiang, Peng, Tu & Zhou leg.” “ Holotype / Stenus fuscus / Hu & Tang” [red handwritten label] (SHNU) . Paratypes: 5♂♂ 3♀♀, same data as for the holotype. (SHNU, cPut) Description. BL: 4.0– 4.3 mm, FL: 1.9–2.1 mm. HW: 0.86–0.90 mm, PL: 0.69–0.73 mm, PW: 0.63–0.69 mm, EL: 0.66–0.71 mm, EW: 0.70–0.79 mm, SL: 0.50–0.53 mm. Similar to S. lizipingus sp. nov. in most respects, but different in the following characters: head 1.11–1.23 times as wide as elytra, lateral portion of head with distinct microsculptures; pronotum relatively longer with PL/ PW: 1.04–1.13; elytra relatively narrower with 0.87–0.93 times as long as wide; elytral disk impressions shallower; punctation of abdominal tergites relatively smaller and slightly sparser than that of S. lizipingus sp. nov. Male. Sternite VIII (Fig. 17) with emargination in the middle of posterior margin; sternite IX (Fig. 18) with very long apicolateral projections, posterior margin serrate. Aedeagus (Figs. 19, 20) with median lobe stout, apical sclerotized area broadly and bluntly, pointed at apex; expulsion clasps large; parameres distinctly longer than median lobe, swollen at apical third, each with 9–12 setae on apico-internal margins. Female. sternite VIII (Fig. 21) slightly prominent at middle of posterior margin; spermatheca (Fig. 22)sclerotized, basal porch very large, spermathecal duct with two bents, apical chamber large and capsule very large. Distribution. China (Sichuan). Remarks. The new species is similar to S. lizipingus sp. nov. both occurred in same locality, and it can be distinguished from the latter by the exterior characters indicated above and the different sexual characters. It is also similar to S. zhuxiaoyui Tang & Zhao, 2008, S. pectorifossatus Tang & Zhao, 2008 and S. erlangshanus Tang & Zhao, 2008 from Sichuan, and can be distinguished from S. zhuxiaoyui and S. erlangshanus by more confluent pronotal punctation, from S. zhuxiaoyui also by larger body size (FL: 1.5–2.0 mm in S. zhuxiaoyui), from S. erlangshanus by lacking distinct subbasal and subapical pronotal impressions and abdominal tergites mostly with microsculptures, from S. pectorifossatus by darker elytral coloration and sparser abdominal punctation. Etymology. The specific name is derived from the lartin word “ fuscus ” after its dark coloration.Published as part of Hu, Cheng-Zhi & Tang, Liang, 2018, Notes on the Stenus indubius group with descriptions of four new species from China (Coleoptera, Staphylinidae), pp. 341-350 in Zootaxa 4471 (2) on pages 345-346, DOI: 10.11646/zootaxa.4471.2.6, http://zenodo.org/record/143976
A Novel Repetitive Controller Assisted Phase-Locked Loop with Self-Learning Disturbance Rejection Capability for Three-Phase Grids
No full textThe synchronization between the power grid and distributed power sources is a crucial issue in the concept of smart grids. For tracking the real-Time frequency and phase of three-phase grids, phase-locked loop (PLL) technology is commonly used. Many existing PLLs with enhanced disturbance/harmonic rejection capabilities, either fail to maintain fast response or are not adaptive to grid frequency variations or have high computational complexity. This article, therefore, proposes a low computational burden repetitive controller (RC) assisted PLL (RCA-PLL) that is not only effective on harmonic rejection but also has remarkable steady-state performance while maintaining fast dynamic. Moreover, the proposed PLL is adaptive to variable frequency conditions and can self-learn the harmonics to be canceled. The disturbance/harmonic rejection capabilities together with dynamic and steady-state performances of the RCA-PLL have been highlighted in this article. The proposed approach is also experimentally compared to the synchronous rotation frame PLL (SRF-PLL) and the steady-state linear Kalman filter PLL (SSLKF-PLL), considering the effect of harmonics from the grid-connected converters, unbalances, sensor scaling errors, dc offsets, grid frequency variations, and phase jumps. The computational burden of the RCA-PLL is also minimized, achieving an experimental execution time of only 12~mu ext{s}. © 2013 IEEE
