An initial deformable surface, which is represented as a closed cylinder, is firstly given. The surface is subject to internal forces describing its implicit smoothness property and external forces attracting it toward the layer data points. And then finite element method is adopted to solve its energy minimization problem, which results a bicubic closed B-spline surface with C^2 continuity. The proposed method can provide a smoothness and accurate surface model directly from the layer data, without the need to fit cross-sectional curves and make them compatible. The feasibility of the proposed method is verified by the experimental results.展开更多

It depends greatly on many stages, such as transcription, post transciption and translation. The regulation of transcription plays the most important role in gene regulation. Thus, it has been considered that the research of positive and negative regulators for the transcription regulation, narticularly in suppressors is very important,展开更多
