arXiv, 2016 Current models indicate that Venus may have been habitable. Complex life may have evolved on the highly irradiated Venus, and transferred to Earth on asteroids. This model fits the pattern of pulses of highly developed life appearing, diversifying and going extinct with astonishing rapidity through the Cambrian and Ordovician periods, and also explains

Realizations of the associahedron and cyclohedron [PDF]
Discrete and Computational Geometry 37 (4) (2007), 517-543, 2005 We describe many different realizations with integer coordinates for the associahedron (i.e. the Stasheff polytope) and for the cyclohedron (i.e. the Bott-Taubes polytope) and compare them to the permutahedron of type A_n and B_n respectively. The coordinates are obtained by an algorithm which uses an oriented Coxeter graph of type A_n or B_n ...

Chronostratigraphic Subdivision of the Cambrian of China
Geologica Acta, 2003 The chronostratigraphic framework for the Cambrian of South China is reviewed. Currently four series and nine stages are recognized. The Cambrian of South China is subdivided into one pre-trilobite-bearing series, the Diandongian Series, and three trilobite-dominated series, the Qiandongian, Wulingian, and Hunanian.
