Revealing the dynamic mechanism and controlling factors of the urban outdoor thermal environment is the necessary theoretical preparation for regulating and improving the urban climate environment. Taking Hangzhou as an example and based on the local climate zones classification system, we investigated the effects of land cover composition and structure on temperature variability at the local scale. The measurement campaign was conducted within four local climate zones (LCZ 2, 4, 5, and LCZ 9) during 7 days in the summer of 2018. The results showed that the temperature difference within the respective LCZ was always below 1.1 ◦C and the mean temperature difference between LCZs caused by different surface physical ◦ Citation: Yan, H.; Yang, S.; Guo, X.; properties was as high as 1.6 C at night. Among four LCZs, LCZ 2 was always the hottest, and LCZ 9 Wu, F.; Wu, R.; Shao, F.; Bao, Z. -
Occasion of Receiving the Seki-Takakazu Prize
特集:日本数学会関孝和賞受賞 On the occasion of receiving the Seki-Takakazu Prize Jean-Pierre Bourguignon, the director of IHÉS A brief introduction to the Institut des Hautes Études Scientifiques The Institut des Hautes Études Scientifiques (IHÉS) was founded in 1958 by Léon MOTCHANE, an industrialist with a passion for mathematics, whose ambition was to create a research centre in Europe, counterpart to the renowned Institute for Advanced Study (IAS), Princeton, United States. IHÉS became a foundation acknowledged in the public interest in 1981. Like its model, IHÉS has a small number of Permanent Professors (5 presently), and hosts every year some 250 visitors coming from all around the world. A Scientific Council consisting of the Director, the Permanent Professors, the Léon Motchane professor and an equal number of external members is in charge of defining the scientific strategy of the Institute. The foundation is managed by an 18 member international Board of Directors selected for their expertise in science or in management. The French Minister of Research or their representative and the General Director of CNRS are members of the Board. IHÉS accounts are audited and certified by an international accountancy firm, Deloitte, Touche & Tomatsu. Its resources come from many different sources: half of its budget is provided by a contract with the French government, but institutions from some 10 countries, companies, foundations provide the other half, together with the income from the endowment of the Institute. Some 50 years after its creation, the high quality of its Permanent Professors and of its selected visiting researchers has established IHÉS as a research institute of world stature. -

Historical Development of the Chinese Remainder Theorem
Historical Development of the Chinese Remainder Theorem SHEN KANGSHENG Communicated by C. TRUESDELL 1. Source of the Problem Congruences of first degree were necessary to calculate calendars in ancient China as early as the 2 na century B.C. Subsequently, in making the Jingchu [a] calendar (237,A.D.), the astronomers defined shangyuan [b] 1 as the starting point of the calendar. If the Winter Solstice of a certain year occurred rl days after shangyuan and r2 days after the new moon, then that year was N years after shangyuan; hence arose the system of congruences aN ~ rl (mod 60) ~ r2 (mod b), . ~ ' where a is the number of days in a tropical year and b the number of days in a lunar month. 2. Sun Zi suanjing [c] (Master Sun's Mathematical Manual) Sun Zi suanjing (Problem 26' Volume 3) reads: "There are certain things whose number is unknown. A number is repeatedly divided by 3, the remainder is 2; divided by 5, the remainder is 3; and by 7, the remainder is 2. What will the num- ber be ?" The problem can be expressed as x --= 2 (mod 3) ~ 3 (mod 5) ~- 2 (rood 7). SUN ZI solved the problem as we do, giving x ~ 140 + 63 -k 30 ~=- 233 ~ 23 (rood 105). 1 Shangyuan is a supposed moment that occurred simultaneously with the midnight of jiazi [v] (the first day of the 60 day cycle), the Winter Solstice and the new moon. 286 SHEN KANGSHENG In speaking of the algorithm yielding these addends in the solution he continued: "In general, for G1 ~ 0(mod 5) ~ 0 (mod 7) = 1 (rood 3), take G1 = 70, G2 ~ 0(rood 3) ~ 0(mod 7) ~ 1 (mod 5), take G2 = 21, G3 ~ 0 (mod 3) ~ 0 (mod 5) ~ (1 rood 7), take G3 = 15. -

ON MATHEMATICAL TERMINOLOGY: CULTURE CROSSING in NINETEENTH-CENTURY CHINA the History of Mathematical Terminologies in Nineteent
ANDREA BRÉARD ON MATHEMATICAL TERMINOLOGY: CULTURE CROSSING IN NINETEENTH-CENTURY CHINA INTRODUCTORY REMARKS: ON MATHEMATICAL SYMBOLISM The history of mathematical terminologies in nineteenth-century China is a multi-layered issue. Their days of popularity and eventual decline are bound up with the complexities of the disputes between the Qian-Jia School who were concerned with textual criticism and the revival of ancient native Chinese mathematical texts, and those scholars that were interested in mathematical studies per se1 (and which we will discuss in a more detailed study elsewhere). The purpose of the following article is to portray the ‘introduction’ of Western mathematical notations into the Chinese consciousness of the late nineteenth century as a major signifying event, both (i) in its own right within the context of the translation of mathematical writ- ings from the West; and (ii) with respect to the way in which the tradi- tional mathematical symbolic system was interpreted by Qing commentators familiar with Western symbolical algebra. Although one might assume to find parallel movements in the commentatorial and translatory practices of one and the same person, nineteenth-cen- tury mathematical activities will be shown to be clearly compartmen- talized. In fact, for the period under consideration here, it would be more appropriate to speak of the ‘reintroduction’ of Western mathematical notations. Already in 1712 the French Jesuit Jean-François Foucquet S. J. (1665–1741) had tried to introduce algebraic symbols in his Aer- rebala xinfa ̅ (New method of algebra). This treatise, which was written for the Kangxi emperor, introduced symbolical 1 In particular, the ‘three friends discussing astronomy and mathematics’ (Tan tian san you dž ) Wang Lai (1768–1813), Li Rui (1763–1820) and Jiao Xun nj (1765–1814). -

π in Other Eastern Countries Japan India In the Edo Period of Japan (1603 to 1868), 3.16 was used for π. But Aryabhata (499 AD) as people recognized that this value was not accurate, different values for π were calculated. Wasan scholars such as Muramatsu Shigekiyo, Seki Takakazu, Kamata Toshikiyo, Takebe Katahiro, and Matsunaga Aryabhata usedp the perimeter of a 384-sided poly- Yoshisuke all made calculations of π, and accomplished results gon to find π ≈ 9:8684.

Note that his approximation is Muramatsu’s Method more accurate than his official value! Shigekiyo Muramatsu published Sanso in 1663. Muramatsu served the Asano family and possibly had a math insti- Brahmagupta (640 AD) tute in Edo (present day Tokyo). In his Brahmagupta used a pattern of inscribed polygons that work, Sanso, Muramatsu arranged prob- increased in the number of sides to calculate the perime- lems published earlier in Japanese math- ter of a circle.p Using these data points, he came to believe ematics texts without answers.

Asano Crest It is in this book that he also showed the calculation of π from the regular inscribed polygon of 32,768 sides. He correctly obtained the Ramanujan (1887-1920) value 3.1415926. Thus, this book was the first to contain a mathematical calculation of π in Japan. 1 Srinivasa Ramanujan found several formulas for π. -
Mathematical Philosophy of Takebe Katahiro
数理解析研究所講究録 第 1831 巻 2013 年 57-65 57 Mathematical Philosophy of Takebe Katahiro Morimoto, Mitsuo 1 Seki Kowa Institute of Mathematics, Yokkaichi University Professor Emeritus, Sophia University Abstract Takebe Katahiro (1664-1739) was a Japanese mathematician, who exposed his philosophy on Mathematics itself and on Mathematical Research. In the Taisei Sankei (1711), he wrote Chapter 4 entitled the “Three Essentials” describing four classes of mathematical problems, the status of parameters in a problem and the classffica- tion of numbers. Note that his thought was based on Chinese traditional philosophy and on the achievement of Japanese mathematics in the early Edo period. Note also he recognized some numbers are not algebraic. In the Tetsujutsu Sankei (1722) he recommended the inductive heuristic method in mathe- matical research and recognized a mathematical research would be successful once the character of a mathematical object and that of a mathematician were accommodated to each other, com- paring his method of calculation of the circular $co$ efficient with that of his master Seki Takakazu and citing his own discovery of the infinite power series expansion formula of an inverse trigono- metric function. The Meiji Restoration (1868) was a tuming point in the history of Japan from the feudalism to the constitutional monarchism. The “ordinance on school system” (1872) of the new gov- emment defined mathematics in Japanese schools to be of “European style” thus abandoning the Japanese traditional mathematics. This policy was proved to be efficient at least for a half century and Takebe’s philosophy on Mathematics was buried in the complete oblivion. 1 Takebe Katahiro Takebe Katahiro 建部賢弘 (1664-1739) was one of great mathematicians in the Edo Period (1603- 1868) of Japan. -
A Review of the History of Japanese Mathematics
Revue d’histoire des math´ematiques, 7 (2001), p. 137–155. A REVIEW OF THE HISTORY OF JAPANESE MATHEMATICS Tsukane OGAWA (*) ABSTRACT. — This review aims to introduce Japanese mathematics to a non- expert and a non-Japanese readership. It briefly characterizes mathematics in Japan, surveys its history, as it developed over the last century, and provides a large (if not exhaustive) bibliography of works in the primary European languages. RESUM´ E´.—APERC¸ U SUR L’HISTOIRE DES MATHEMATIQUES´ JAPONAISES. Le but de cette note est de pr´esenter les math´ematiques japonaises `a un public non sp´ecialis´e dans le domaine. Les math´ematiques au Japon sont bri`evement caract´eris´ees, leur histoire, telle qu’elle s’est d´evelopp´ee durant le dernier si`ecle, est pass´ee en revue et finalement une importante bibliographie dans les principales langues europ´eennes est propos´ee, mˆeme si elle ne peut pr´etendre `a l’exhaustivit´e. 1. INTRODUCTION – NOT ONLY SANGAKU The custom of hanging sangaku ( ), wooden plates on which are inscribed mathematical problems and their answers, under the roofs of shrines in the Edo period (1603–1867) in Japan is familiar enough to have been illustrated and described in Scientific American, May 1998 [Rothman 1998]. It is, however, obvious that sangaku is not all there is to Japanese mathematics. It would be fallacious to consider that the essence of Japanese mathematics reveals itself in sangaku. As a beginning, this essay attempts briefly to introduce Japanese mathematics to a non-Japanese readership. It will answer the following questions : 1) What kind of mathematical disciplines developed in Japan ? 2) How were mathematical expressions written in vertical typesetting ? 3) How did the Japanese calculate ? 4) Is it true that, lacking proofs, Japanese mathematics was not logical ?

Creating Heresy: (Mis)Representation, Fabrication, and the Tachikawa-Ryū
Creating Heresy: (Mis)representation, Fabrication, and the Tachikawa-ryū Takuya Hino Submitted in partial fulfillment of the Requirement for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2012 © 2012 Takuya Hino All rights reserved ABSTRACT Creating Heresy: (Mis)representation, Fabrication, and the Tachikawa-ryū Takuya Hino In this dissertation I provide a detailed analysis of the role played by the Tachikawa-ryū in the development of Japanese esoteric Buddhist doctrine during the medieval period (900-1200). In doing so, I seek to challenge currently held, inaccurate views of the role played by this tradition in the history of Japanese esoteric Buddhism and Japanese religion more generally. The Tachikawa-ryū, which has yet to receive sustained attention in English-language scholarship, began in the twelfth century and later came to be denounced as heretical by mainstream Buddhist institutions. The project will be divided into four sections: three of these will each focus on a different chronological stage in the development of the Tachikawa-ryū, while the introduction will address the portrayal of this tradition in twentieth-century scholarship.
