The computational results of the nonlinear disturbance development in plane Poiseuille flow for both methods are presented and compared in detail. It is acknowledged that the Chebyshev collocation method has higher precision than the other one, especially for near netural situation.展开更多

In this paper, we show that Chelyshkov-tau method is a very effective tool in numerically solving this equation. To show the accuracy and the efficiency of the method, several problems are implemented and the comparisons are given with other methods existing in the recent literature. The results of numerical tests confirm that Chelyshkov-tau method is superior to other existing ones and is highly accurate.展开更多

According to the post-source decay (PSD) in MALDI-TOF-MS, there are two different patterns of cleavage in phosphopeptides, which can be used to determine the phosphorylated site in peptides. In the synthetic tau peptides, the fragmentation at proline residue occurs strongly and this is useful to determine the structure of tau peptides.展开更多
