Research ArticleOpen accessIn the abstractNeuronal Functions of Protein Phosphatase 2AHung-Tat Leung, Ning WangReversible protein phosphorylation is a common and important form of protein posttranslational modification which determines the proteins’ activities, substrate specificity and inhibitions or degradations, depending on the specific amino acid residue, or combination of residues, being targeted. While protein phosphorylations by kinases have been well studied, the importance of protein dephosphorylation by phosphatases has emerged over the past two decades … …Neuroscience International, Vol. 4, Issue 2 · 1 Apr 2014 · 7,783 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Algorithm for Fractal Coding Using Self Organizing MapS. Bhavani, k. ThanushkodiProblem statement: In medical imaging, lossy compression schemes are generally not used due to possible loss of useful clinical information and also degradations may result in lossy compression owing to operations like enhancement. As the medical images are huge in size a good lossy compression technology is required to store them in medical archives in an economical manner. There is … …Journal of Computer Science, Vol. 8, Issue 6 · 15 Mar 2012 · 7,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining the Optimal Software Rejuvenation Schedule via Semi-Markov Decision ProcessHiroyuki Eto, Tadashi DohiSoftware rejuvenation is a preventive and proactive maintenance policy that is particularly useful for counteracting the phenomenon of software aging. In this study we consider an operational software system with multiple degradations and derive the optimal software rejuvenation policy minimizing the expected operation cost per unit time in the steady state, via the dynamic programming approach. Especially, we show analytically … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,979 accessesView PDFCite
