In this paper, a proposed encryption scheme based on Henon chaotic system (PESH) is presented in order to meet the requirements of secure image transfer. Scheme based on Henon chaotic system by Chen Wei-bin et al., will be designated here as (SHCH). SHCH and a proposed encryption scheme (PESH) are applied for encrypting by changing the values of the image pixels. Combination of shuffling the po...
Exercise training (Ex) has been recommended for its beneficial effects in hypertensive states. The present study evaluated the time-course effects of Ex without workload on mean arterial pressure (MAP), reflex bradycardia, cardiac and renal histology, and oxidative stress in two-kidney, one-clip (2K1C) hypertensive rats. Male Fischer rats (10 weeks old; 150-180 g) underwent surgery (2K1C or SHA...
Image encryption using chaotic maps has been established a great way. The study shows that a number of functional architecture has already been proposed that utilize the process of diffusion and confusion. However, permutation and diffusion are considered as two separate stages, both requiring image-scanning to obtain pixel values. If these two stages are mutual, the duplicate scanning effort c...
We define and study the regularity of distance maps on geodesically complete spaces with curvature bounded above. prove that such a regular map is locally Hurewicz fibration. This can be regarded as dual concept Perelman's in geometry Alexandrov below. As corollary we obtain sphere theorem for CAT(1) spaces.
In this paper, we present a novel approach to create the new chaotic map and propose an improved image encryption scheme based on it. Compared with traditional classic one-dimensional chaotic maps like Logistic Map and Tent Map, this newly created chaotic map demonstrates many better chaotic properties for encryption, implied by a much larger maximal Lyapunov exponent. Furthermore, the new chao...
We analyzed the regulation of expression of a human cytomegalovirus (HCMV) early transcription unit encoded by EcoRI fragments R and d (map units, 0.682 to 0.713), located within the long unique segment of the genome. This region specified a 2.2-kilobase class of spliced transcripts which encode several related proteins. To define important upstream regulatory elements of this gene, we generate...
A radiation hybrid (RH)-derived physical map of 25 markers on the feline X chromosome (including 19 Type I coding loci and 6 Type II microsatellite markers) was compared to homologous marker order on the human and mouse X chromosome maps. Complete conservation of synteny and marker order was observed between feline and human X chromosomes, whereas the same markers identified a minimum of seven ...
The Tabby markings of the domestic cat are unique coat patterns for which no causative candidate gene has been inferred from other mammals. In this study, a genome scan was performed on a large pedigree of cats that segregated for Tabby coat markings, specifically for the Abyssinian (Ta-) and blotched (tbtb) phenotypes. There was linkage between the Tabby locus and eight markers on cat chromoso...
