In this paper, a novel approach is proposed for denoising of Chinese calligraphy tablet documents. The method includes two phases: First, a partial differential equations (PDE) based the total variation model and Otsu thresholding method are used to preprocess the calligraphy document image. Second, a new method based on run-length statistics and structure charac- teristics of Chinese characters is proposed to remove some random and ant-like noises. This includes the optimal threshold se- lection from histogram of run-length probability density, and improved Hough transform algorithm for line shape noise detection and removal. Examples are given in the paper to demonstrate the proposed method.

The present review describes recent advances in application of accommodating intraocular lenses （AIOLs）. Standard monofocal intraocular lenses （MIOLs） only correct distance vision, while AIOLs are designed to allow both good distance vision and near vision, which is achieved through the contraction and relaxation of ciliary muscles by providing transformation of the axial movement or curvature of the lens. Thus, AIOLs may be a better choice for those patients who demand a higher level of visual performance. Since techniques to analyze the performance of AIOLs have not been standardized, and there is a variety of both subjective and objective methods, it is hard to measure the performance of these intraocular lenses. By evaluating advantages and disadvantages of various AIOLs, and introducing techniques for measurement the performance postoperative, this paper can provide some relative information on choosing the type of AIOLs in the clinic.

The seed-specific promoter and transit peptide were amplified and fused to the three genes phbA, phbB and phbC encoding PHB synthetic enzymes, respectively. Seed-specific expression vectors pSCB containing phbC and phbB, and pSCAB containing phbC, phbB and phbA, were constructed by introducing the genes with promoter and peptide into the binary vector pBI101. Transgenic Brassica napus H165 were obtained by Agrobacterium-mediated transformation with these vectors. They were confirmed by PCR, Southern and RT-PCR analyses.
