A new boundary element approach of modeling singular stress fields of plane V-notch problems (2009)

In this paper, a new boundary element (BE) approach is proposed to determine the singular stress field in plane V-notch structures. The method is based on an asymptotic expansion of the stresses in a...

Evaluation of the stress singularities of plane V-notches in bonded dissimilar materials (2009)

Niu, Z., Ge, D., Cheng, C., Ye, J., Recho, N.

According to the linear theory of elasticity, there exists a combination of different orders of stress singularity at a V-notch tip of bonded dissimilar materials. The singularity reflects a strong...

Simplified solutions for the stress transfer in concrete beams bonded with FRP plates (2008)

Yang, J., Ye, J., Niu, Z.

Strengthening of concrete beams by the external plate bonding technique has become an important research area over the last two decades, particularly with the increasing applications of the advanced...

The internal chondrocyte-specific promoter of the chick type III collagen gene is activated by AP1 and is repressed in fibroblasts by a complex containing an LBP1-related protein (1999)

Zhang, Y, Niu, Z, Cohen, AJ, Adams, SL

The chick type III collagen gene contains two promoters that are preferentially expressed in different cell types and are separated by over 20 kb of DNA containing 23 exons (1997)

The chick type III collagen gene contains two promoters that are preferentially expressed in different cell types and are separated by over 20 kb of DNA containing 23 exons.

Zhang, Y, Niu, Z, Cohen, A J, Nah, H D, Adams, S L

Type III collagen is present in prechondrogenic mesenchyme, but not in cartilages formed during endochondral ossification. However, cultured chick chondrocytes contain an unusual transcript of the...

The internal chondrocyte-specific promoter of the chick type III collagen gene is activated by AP1 and is repressed in fibroblasts by a complex containing an LBP1-related protein.

Zhang, Y, Niu, Z, Cohen, A J, Adams, S L

The chick type III collagen gene contains an internal promoter in intron 23 in addition to the promoter preceding exon 1. The internal promoter, which is used preferentially in cultured chondrocytes,...
