TWIST protein has been implicated in neoplastic transformation and development of some cancers. In this study, we aimed to investigate the expression of TWIST in gastric cancer and its clinical significance.

In this paper we discuss the thermodynamic property of the F-AF phase transition by starting from Kittle's free energy expression of the antiferroelectrics. Both the characteristics of the polarization and the relation obtained by the theory are in good agreement with the experiments.

Abstract: In this paper, the principle of maximum power losses for the incompressible viscous fluid proposed by professor Chien Wei-zang is extended to the hydrodynamic problems of a special class of non-Newtonian fluid—generalized Newtonian fluid. The constraint conditions of variation are eliminated by the method of identified Lagrangian multipliers and a generalized variational principle is established.

Abstract: This paper proposes a new method to improve the stability condition of difference scheme of a parabolic equation. Necessary and sufficient conditions of the stability of this new method are given and proved. Some numerical examples show that this method has some calculation advantages.
