A new approach for 2D parametric design based on the mapping of constraints for graphical primitives is presented.

Basing on the existing theory of crisp matroids and fuzzy matroids, the paper studies mainly closed regular fuzzy matroids including its sub-matroid when it’s good-base; the exchange of fuzzy bases; the relations between the fuzzy bases and the fuzzy circuits; defining the base-graph and studying its properties.

~Gγ/~Aγ,~Aγ~I/~Aγ~T Ratios of Fetal Hemoglobin of Han,Hui,Uygur and Kazak Newborns in Xinjiang and Gene Mapping Analysis of Two Cases with Abnormal Ratio;

Applications and prospects of fluorescence in situ hybridization on plant cytogenetics and gene mapping;

The recent advances of genetic linkage mapping in domestic animal such as cattle、pig、 chicken and sheep were summarized in this paper, including the kinds、methods of study、progress of gene linkage mapping and the application of gene mapping in domestic animal breeding.

Fast face detection combine both feature-based and image-based approach;

In this paper, we describe an image-based rendering technique called Inverse Concentric Mosaics (ICM) which is based on Concentric Mosaics (CM) .

In recent years, we can seen clearly the trend of increasing number of researchers\' interest in image-based modeling technology for its advantages of low-cost, relatively fast speed of modeling.
