TWISTED QUADRATIC MOMENTS FOR DIRICHLET L-FUNCTIONS

Stéphane R. Louboutin 대한수학회 2015 대한수학회보 Vol.52 No.6

Given c, a positive integer, we set M(f, c) := 2/Φ(f) ∑ χ∈X− f χ(c)|L(1, χ)|2, where X− f is the set of the Φ(f)/2 odd Dirichlet characters mod f > 2, with gcd(f, c) = 1. We point out several mistakes in recently published papers and we give explicit closed formulas for the f’s such that their prime divisors are all equal to ±1 modulo c. As a Corollary, we obtain closed formulas for M(f, c) for c 2 {1, 2, 3, 4, 5, 6, 8, 10}. We also discuss the case of twisted quadratic moments for primitive characters.

Effectiveness of anchorage with temporary anchorage devices during anterior maxillary tooth retraction: A randomized clinical trial

Stéphane Barthélemi,Alban Desoutter,Fatoumata Souaré,Frédéric Cuisinier 대한치과교정학회 2019 대한치과교정학회지 Vol.49 No.5

Objective: This study evaluated the efficiency of anchorage provided by temporary anchorage devices (TADs) in maxillary bicuspid extraction cases during retraction of the anterior teeth using a fixed appliance. Methods: Patients aged 12 to 50 years with malocclusion for which bilateral first or second maxillary bicuspid extractions were indicated were included in the study and randomly allocated to the TAD or control groups. Retraction of the anterior teeth was achieved using skeletal anchorage in the TAD group and conventional dental anchorage in the control group. A computed tomography (CT) scan was performed after alignment of teeth, and a second CT scan was performed at the end of extraction space closure in both groups. A three-dimensional superimposition was performed to visualize and quantify the maxillary first molar movement during the retraction phase, which was the primary outcome, and the stability of TAD movement, which served as the secondary outcome. Results: Thirty-four patients (17 in each group) underwent the final analysis. The two groups showed a significant difference in the movement of the first maxillary molars, with less significant anchorage loss in the TAD group than that in the control group. In addition, TAD movement showed only a slight mesial movement on the labial side. On the palatal side, the mesial TAD movement was greater. Conclusions: In comparison with conventional dental anchorage, TADs can be considered an efficient source of anchorage during retraction of maxillary anterior teeth. TADs remain stable when correctly placed in the bone during the anterior tooth retraction phase.

Hagiography in the West and the Bollandists : An Overview

Stéphane Mercier 수원교회사연구소 2014 교회사학 Vol.0 No.11

이 논문은 서양 성인전기학(聖人傳記學)의 발전에 볼랑디스트(Bollandists)가 기여한 업적들과 그들의 활동 역사를 집중적으로 소개하는 짧은 글이다. 이와 관련해서, 이글은 1,600여 년에 걸쳐 만들어진 성인전 관련 문헌들과 17세기 초 로스웨이드가 내놓은 시발적인 작업 이후에 볼랑이 영성 전기 총서를 집성하는 과정에서 저 유명한 《성인 열전》(Acta Sanctorum)을 어떤 방식으로 기획했는지를 밝혔다. 이 글은 크게는 가톨릭의 영성 신학의 맥락 안에서 과학으로서 성인전기학에 대한 몇 개의 주석에 해당하는 해명을 덧붙였다. 아쉽지만, 총서의 운명에 대해서는 이 글에서는 다루지 못했다. 이는 후속 연구에서 상세하게 소개하겠다. This short essay focuses on the work of the Bollandists and their contribution to the evolution of hagiography in the Western world. It shows how Bollandus himself, after sixteen centuries of hagiographical literature and Rosweydus’ initial draft, planned the famed Acta Sanctorum series in the wake of previous collections of spiritual biographies. The fate of the collection is examined next; and the paper concludes with a few notes about hagiography qua science within the larger framework of Catholic spiritual theology.

Science à paillettes et « abus de confiance » Discussion autour d’un nouveau type de « Lève-toi et marche »

Stéphane Amato 고려대학교 응용문화연구소 2015 에피스테메 Vol.0 No.14

This article aims at analyzing the 2014 football world cup kick-off, which highlighted a paraplegic person equipped with an "exoskeleton guided by thought". In a first part, the ritualistic framework which surrounds the event is described. It seems to establish a mediation of a symbolic or even religious nature, conducive to building trust in an announced "miracle". In a second part, the event itself is described in a factual fashion. It is clearly proven that the miracle didn't occur. Some elements of media coverage are provided, as well as internet users' reactions. It seems there was a distortion in the perceptions of the event. In a third part, after having shown that a rational reading of the announcement seemed to imply that it was impossible to carry out, a theoretical framework with a psychosocial inspiration is suggested to attempt to better explain the distortions in individuals' perceptions, during this event. Cet article se propose d’analyser le coup d’envoi de la Coupe du monde de football 2014, qui a mis en scène une personne paraplégique équipée d’un « exosquelette piloté par la pensée ». Dans une première partie, le cadre rituel qui entoure l’événement est décrit. Il semble instaurer une médiation d’ordre symbolique voire religieuse, propre à favoriser la confiance dans un « miracle » annoncé. Dans une seconde partie, l’événement lui-même est décrit de façon factuelle. Il est clairement montré que le « miracle » n’a pas eu lieu. Certains éléments de couverture médiatique sont fournis, ainsi que des réactions d’internautes. Il semble qu’il y ait eu altération des perceptions de l’événement. Dans une troisième partie, après avoir montré qu’une lecture rationnelle de l’annonce semblait impliquer l’impossibilité de sa réalisation, un cadre théorique d’inspiration psychosociale est proposé pour tenter d’expliquer davantage l’altération des perceptions des individus, lors de cet événement.

La contamination du sacré Pensée magique ou réalité sémiotique

Stéphane Dufour 고려대학교 응용문화연구소 2017 에피스테메 Vol.0 No.17

This paper proposes a socio-semiotic analysis of the question of contamination of the sacred on the basis of contact with relics, which runs through numerous anthropological studies. While anthropological texts describe the idea of transferring the sacred from relics as a chemical operation with clearly defined consequences, they say nothing about the question of meaning. How is meaning being created when belief has it that the sacred is spread about, projected from the relic onto other objects? How can the contamination of the sacred be translated into the contamination of sacred meaning?

Les experts corporels: entre hériter, transmettre et innover

Stéphane Héas 고려대학교 응용문화연구소 2014 에피스테메 Vol.0 No.12

Experts (oenologist, nose of perfumery, fakir, contortionist, imitator, etc.) develop a sensitivity, a body’s empowered to be able to live professionally. Enter in this peculiar profession is often realized through transmission by a peer. Over time, tangible performance may be decline, threatening the existence of such professional experts. The question of the transmission of these specific knowledges intervenes in the course of these professionals, investigated by semi-structured interviews.

We report on the first error-free terahertz (THz) wirelesscommunication at 0.310 THz for data rates up to 8.2 Gbps using a18-GHz-bandwidth GaAs/AlGaAs field-effect transistor as a detector. This result demonstrates that low-cost commercially-availableplasma-wave transistors whose cut-off frequency is far below THzfrequencies can be employed in THz communication. Wirelesscommunication over 50 cm is presented at 1.4 Gbps using a unitravelling-carrier photodiode as a source. Transistor integration isdetailed, as it is essential to avoid any deleterious signals that wouldprevent successful communication. We observed an improvementof the bit error rate with increasing input THz power, followed bya degradation at high input power. Such a degradation appearsat lower powers if the photodiode bias is smaller. Higher-dataratecommunication is demonstrated using a frequency-multipliedsource thanks to higher output power. Bit-error-ratemeasurementsat data rates up to 10 Gbps are performed for different inputTHz powers. As expected, bit error rates degrade as data rate increases. However, degraded communication is observed at somespecific data rates. This effect is probably due to deleterious cavityeffects and/or impedance mismatches. Using such a system, realtimeuncompressed high-definition video signal is successfully androbustly transmitted.

Tricks of the Trade: Debt and Imposed Sovereignty in Southernmost Kham in the Nineteenth to Twentieth Centuries

Stéphane Gros 고려대학교 민족문화연구원 2016 Cross-Currents Vol.- No.19

Southernmost Kham, which borders Burma and Yunnan Province, remained at the juncture of several mutually competing political centers until the first half of the twentieth century. On the fringes of Tibetan, Naxi, and Chinese expansion and increasing political control, several Tibeto- Burman–speaking groups such as the Drung and Nung gradually became integrated into their neighbors’ polities. Their political dependency often arose from trading with and accepting loans from commercial agents and from the intermediaries of local rulers, Naxi and Tibetans alike. This article addresses this practice of providing credit, which was developed at the expense of impoverished groups who were often obliged to accept the terms of the transaction. The author particularly emphasizes the connections between this system of debt dependency, the relationship between creditors and debtors that has to be considered in terms of exchange and reciprocity, and the question of political legitimacy. Within this broader context of regional interethnic relations, the article provides a detailed analysis of the concrete terms of the political relationship that existed between Drung communities and Tibetan chiefs of Tsawarong, which contributes to an understanding of the workings of this relationship and its economic, territorial, and even ritual components.
