Fully discrete nonlinear galerkin methods for Kuramoto-Sivashinsky equation and their error estimates
In this paper the uniform error estimates with respect to t ∃ [0, ∞] of the nonlinear Galerkin method are given for the long time integration of the Kuramot-Sivashinsky equation. The nonlinear Galerkin method is ...

A numerical approach to hopf bifurcation points
The computation of Hopf bifurcation points for differential equations with a parameter α is considered. It is well known that the Hopf bifurcation is well characterized by the fact that the first (largest) Lya...

Theoretical study on characteristic ionic radii
The characteristic radii for univalent cations and anions were defined by the classical turning point of the electron movement in an ion. The numerical results of the elements from firstto third-rows in the pe...

Identity, distribution, and development of polydendrocytes: NG2-expressing glial cells
Cells that express the NG2 proteoglycan (NG2+ cells) comprise a unique population of glial cells in the central nervous system. While there is no question that some NG2+ cells differentiate into oligodendrocyt...

Alkylammonium cations treating and K-Ar dating of illite from mudstones
Two kinds of mudstones from the Tarim Basin and the Tuha Basin were treated with C8 and C18 alkylam-monium cations. Both of them were dated by the K-Ar method. One kind of rock contains mainly diagenetic illite, ...
