✦ Synopsis

A new shape descriptor is presented in this paper, which is based on the centroid-radii model and the Haar wavelet transform. With this descriptor, we can achieve more accurate shape feature and implement more efficient retrieval under multi-resolution. In addition, our method is robust to translation, scaling and rotation. The experimental results show the competitiveness of this descriptor.

## Abstract __Experimental and theoretical investigations concerning the second‐to‐last step of the DXP/MEP pathway in isoprenoid biosynthesis in plants are reported. The proposed intrinsic or late intermediates 4‐oxo‐DMAPP (__**__12__**__) and 4‐hydroxy‐DMAPP (__**__11__**__) were synthesized in d
