This paper treats Chinese species of the rove beetle genus Plastus Bernhauer, 1903, subgenus Plastus s. str. (Coleoptera, Staphylinidae, Osoriinae). None of the 87 previously described species of this subgenus are known from China. The following five new species are described and illustrated: Plastus Plastus amplus Wu & Zhou, sp. n. from Xizang, Plastus Plastus rhombicus Wu & Zhou, sp. n. from ...

This paper is an experience report describing the Learn@WU learning environment, which to our knowledge is one of the largest operational learning environments in higher education. The platform, which is entirely based on open source components, enjoys heavy usage by about 4,000 WU freshmen each year. At present, the learning environment supports 18 high-enrollment courses and contains more tha...

In this paper, we study the notion of solvable $L$-subgroup of an $L$-group and provide its level subset characterization and this justifies the suitability of this extension. Throughout this work, we have used normality of an $L$-subgroup of an $L$-group in the sense of Wu rather than Liu.

IN THIS paper we consider the following question: for how singular a space is it possible to define cobordism invariant characteristic numbers? This question was one of the motivations behind the development of intersection homology: there are many singular spaces (complex algebraic varieties, for example) for which Whitney [40], Chern [28], and L [ 1 S] classes can be defined, but these are ho...

An improved Ritt-Wu’s decomposition (of an algebraic set into the union of irreducible varieties) algorithm is given. The algorithm has been used to prove geometric theorems that Wu’s original method addresses. Unlike Wu’s original approach, nondegenerate conditions are given explicitly at the beginning, not generated during the proof process. A program based on this improved version of the alg...
