Integrin-linked kinase (ILK) is a highly conserved serine-threonine protein kinase which has been implicated in the regulation of various cellular processes. Previously, we have demonstrated that overexpression of ILK correlates with malignant phenotype in non-small cell lung cancer. Furthermore, forced overexpression of ILK promotes lung cancer cell(More)
Texture is the vital feature for remote sensing image classification, however, it is hard to be described and recognized by computer vision. As a result, lots of approaches have been presented to identify texture image. Among these methods, support vector machine (SVM) is the most successfully used one, which takes advantages of avoiding local optimum,(More)
In this study, we report a new phenomenon dealing with the size-dependent behavior of the wall thickness of block copolymer vesicles, especially the decrease in wall thickness with decreasing vesicle size. Four vesicle-forming copolymers from the polystyrene-b-poly-(acrylic acid) (PS-b-PAA) family (i.e., PS(500)-b-PAA(50), PS(310)-b-PAA(28),(More)
Quantitative analysis of superoxide anion (O2(·-)) has increasing importance considering its potential damages to organism. Herein, a novel Mn-superoxide dismutase (MnSOD) mimics, silica-manganous phosphate (SiO2-Mn3(PO4)2) nanoparticles, were designed and synthesized by surface self-assembly processes that occur on the surface of silica-phytic acid(More)
An optimization algorithm called hybrid rice optimization algorithm (HRO) is proposed in the paper which is inspired by the breeding process of three line hybrid rice. The three line are sterile line, maintainer line, restorer line. The sterile line is hybridized with the maintainer line to produce the hybrid rice. The restorer line keeps the fine(More)
Image Segmentation is a key process in image analysis and computer vision. Otsu is a simple but effective thresholding method, which is widely used for image segmentation. However, when one-dimensional Otsu is generalized to multi-threshold, the increased amount of computation will break down its efficiency and limits its application. Some evolutionary(More)
The image thresholding approach based on the basis of 2-D maximum entropy has better segmentation performance by the use of local space information of pixels, but it is unpractical for heavy computation required by this method. In the paper, an image segmentation technology based on cuckoo search and 2-D maximum entropy is presented, which views the seeking(More)
Image enhancement is an important step in image processing, and the enhancement approach based on normalization of incomplete beta function is able to achieve ideal enhanced results. However, it often requires human intervention or is time-consuming to obtain good parameters, which still remains an issue not fully solved. In practice, it is an optimization(More)
Numerical control machine tools are widely used in the manufacturing nowadays. The engineers often have difficulties discussing with another engineer about the problem in the CAM work, so a convenient tool for this is needed. In this paper, a framework of collaborative CAM simulation environment is presented for the goal of virtual enterprise. The main(More)
