Sp1-like transcription factors are characterized by three highly homologous C-terminal zinc finger motifs that bind GC-rich sequences. These proteins behave as either activators or repressors and have begun to be classified into different subfamilies based upon the presence of conserved motifs outside the zinc finger domain. This classification predicts(More)
Currently, there is no serum marker that is routinely recommended for lung cancer. Therefore, the aim of the present study was to demonstrate that plasma vascular endothelial growth factor 165 (VEGF 165) may be a potential marker for advanced lung cancer. Lung cancer is the leading cause of cancer-related mortality worldwide, therefore, it is important to(More)
With the rapid and the fast development of artificial intelligence technology, intelligent tutoring Systems (ITSs) are becoming one of the most important area of research and development. Intelligent tutoring Systems have very good impact for making computer-based instruction more adaptive and interactive. Intelligent tutoring Systems are becoming important(More)
Digital watermarking is hiding the information inside a digital media. Its widely used in copyright protection of digital images. This paper presents a comparative study of digital watermarking techniques in frequency domain and explores the role of Discrete cosine transform DCT, Discrete wavelet transform DWT and Contourlet transform CT in generating(More)
Structured-population Genetic Algorithm (GA) usually leads to more superior performance than the panmictic genetic algorithm; since it can control two opposite processes, namely exploration and exploitation in the search space. Several spatially structured-population GAs have been introduced in the literature such as cellular, patchwork, island-model,(More)
