周运中: Zhongguo Nanyang gudai jiaotong shi 中国南洋古”背栖梨, Zhou Yunzhong

This ambitious book, in short characters, with a preface by Wang Rigen 王日根, the series editor, can almost be read as a sequel to Zhou Yunzhong’s earlier monograph, Zheng He xia Xiyang xin kao 和下西洋新考 (Beijing 2013), reviewed for Archipel 89 (2015). While the focus of the earlier work is on Chinese navigation under the Ming dynasty and the so-called Zheng He map, the new monograph investigates the long period from the late Zhou through to the fourteenth century, up to the decades preceding the ..

Six New Species and 1 New Species Record of Orthotrichia (Trichoptera: Hydroptilidae) from China

Six new species of the caddisfly genus Orthotrichia are described and illustrated from China, namely Or. apophysis Zhou & Yang, sp. nov.; Or. latiramifera Zhou & Yang, sp. nov.; Or. cornuta Zhou &Yang, sp. nov.; Or. discedata Zhou & Morse, sp. nov.; Or. cuspidigera Zhou & Yang, sp. nov.; and Or. subrhomba Zhou & Morse, sp. nov.. One species, Or. terpsichore Malicky & Chantaramongkol, 2007, is recorded for the first time from China, bringing the number of species of the genus known from China to 14. Of these, 10 species are distributed among 3 species groups of Marshall (1979), with 4 species unassigned. The known distributions for all the Chinese Orthotrichia species are provided

Testing Technicolor Models via Top Quark Pair Production in High Energy Photon Collisions

Pseudo-Goldstone boson contributions to $t\bar{t}$ production rates in technicolor models with and without topcolor at the $\sqrt{s}=0.5 and 1.5$ TeV photon colliders and hadron colliders are reviewed. For reasonable ranges of the parameters, the contributions are large enough to be experimentally observable. Models with topcolor, without topcolor and the MSSM with $\tan\beta\geq 1$ can be experimentally distinguished.Comment: Talk given by H.Y.
