Research ArticleOpen accessIn the abstractEnhancement of Nutritional Quality of Wheat (Triticum aestivum) by Metabolic Engineering of Isoflavone PathwayAhmed Mohamed El-Shehawi, Abdelmegid Ibrahim Fahmi, Mona Mohamed Elseehy, Hesham Ahmed NagatyIsoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy). In this report, isoflavonoids were expressed in wheat (Triticum aestivum) via introducing the key enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,135 accessesView PDF Cite

Research ArticleOpen accessIn the abstractINDUCED PLURIPOTENT STEM CELLS AND THEIR IMPLICATION FOR BIOMEDICAL SCIENCESMaria Csobonyeiova, Stefan Polak, Lubos DanisovicThe groundbreaking discovery, that somatic mammalian cells can be epigenetically reprogrammed to a pluripotent state through the exogenous expression of the transcription factors Oct4, Sox2, Klf4 and c-myc, has yielded a new cell type for potential application in regenerative medicine, the induced Pluripotent Stem Cells (iPSCs). Since the first demonstration of creating iPSCs in 2006 great efforts have been made … …OnLine Journal of Biological Sciences, Vol. 13, Issue 4 · 3 Oct 2013 · 7,024 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDetection of Occluded Face Image using Mean Based Weight Matrix and Support Vector MachineG. Nirmala Priya, R. S.D. Wahida BanuProblem statement: Face occlusion is a very challenging problem in face recognition. The performance of face recognition system decreases drastically due to the presence of partial occlusion on the face. Extracting discriminative features to achieve accurate detection versus computational overhead in extracting the features, which affects the classification speed, would be a sustained problem. The objective of this study is … …Journal of Computer Science, Vol. 8, Issue 7 · 5 Jul 2012 · 7,043 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordImproving the Performance of Machine Learning Based Multi Attribute Face Recognition Algorithm Using Wavelet Based Image Decomposition TechniqueS. Sakthivel, M. RajaramProblem statement: Recognizing a face based attributes is an easy task for a human to perform; it is closely automated and requires little mental effort. A computer, on the other hand, has no innate ability to recognize a face or a facial feature and must be programmed with an algorithm to do so. Generally, to recognize a face, different kinds … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,907 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Improved Face Recognition Technique Based on Modular LPCA ApproachMathu Soothana S. Kumar, Retna Swami, Muneeswaran KaruppiahProblem statement: A face identification algorithm based on modular localized variation by Eigen Subspace technique, also called modular localized principal component analysis, is presented in this study. Approach: The face imagery was partitioned into smaller sub-divisions from a predefined neighborhood and they were ultimately fused to acquire many sets of features. Since a few of the normal facial features of … …Journal of Computer Science, Vol. 7, Issue 12 · 22 Oct 2011 · 6,950 accessesView PDF Cite
