Speeding-Up Color FIC Using
In this paper, speeding-up fractal color image compression technique based on zero-mean method by adding symmetry predictor to reduce the number of isometric trails from 8 to one trail. The first order centralized moments are used to index each domain and range blocks onto one of eight possible isometric states. At each range domain the indices of both domain and range blocks are passed through...
متن کاملControlling Allosteric Networks in Proteins.
Allosteric transition, defined as conformational changes induced by ligand binding, is one of the fundamental properties of proteins. Allostery has been observed and characterized in many proteins, and has been recently utilized to control protein function via regulation of protein activity. Here, we review the physical and evolutionary origin of protein allostery, as well as its importance to ...
متن کاملBacterial Ice Crystal Controlling Proteins
Across the world, many ice active bacteria utilize ice crystal controlling proteins for aid in freezing tolerance at subzero temperatures. Ice crystal controlling proteins include both antifreeze and ice nucleation proteins. Antifreeze proteins minimize freezing damage by inhibiting growth of large ice crystals, while ice nucleation proteins induce formation of embryonic ice crystals. Although ...
متن کاملFic Proteins of Campylobacter fetus subsp. venerealis Form a Network of Functional Toxin–Antitoxin Systems
Enzymes containing the FIC (filamentation induced by cyclic AMP) domain catalyze post-translational modifications of target proteins. In bacteria the activity of some Fic proteins resembles classical toxin-antitoxin (TA) systems. An excess of toxin over neutralizing antitoxin can enable bacteria to survive some stress conditions by slowing metabolic processes and promoting dormancy. The cell ca...
متن کاملColor FIC by Zero-Mean Method
In this paper, a fractal compression technique based on zero-mean block matching is utilized as unconventional affine mapping. In this method the mean of the range blocks is used instead of traditional offset parameter. This will reduce and simplify the computations of the affine parameter during the encoding process. This method is tested on 24 bits/pixel color image. The data of the color com...
