To solve the routing and wavelength assignment problem in the optical network, this paper put forward the metric model with sparse wavelength conversion and rou
In this paper, by the Gelfand representation theory and the Silov idempotents theorem, we first obtain a central decomposition theorem related to a unital semi-

As baccatin Ⅲ is an immediate diterpenoid precursor of taxol, the increase of baccatin Ⅲ is beneficial to the biosynthesis of taxol. Addition of methyl jasmon
The Hartree-Fock and cluster model methods have been employed to investigate interactions of methanthiol or dimethyl sulfide on zeolites. Molecular complexes fo
Taking the mouse as a model, the experimental method of observing the morphology of meiotic spindles and chromosomes in mature oocytes were investigated in orde
The demand for propylene has been growing recently. The concentration of olefins in the gasoline is strictly limited by the related environmental regulations. T
Using economics and game theory, two kinds of models have been proposed in this paper under the assumption that foreign and domestic firms behave under the cond
