TL;DR: This study presents a novel chaotic–neural network of image encryption and decryption image applied to the domain of medical to ensure the safety of medical images with a less complex algorithm compared with the existing methods.
Abstract: This study presents a novel chaotic–neural network of image encryption and decryption image applied to the domain of medical. The main objective behind the proposed technique is to ensure the safety of medical images with a less complex algorithm compared with the existing methods. In order to improve the robustness, the totality of the pixels related to the host image is XORed with a generation key. After that, with a chaotic system (logistic map), the binary sequence is generated in order to set the weights wij and bias bi of neuron network with the goal of encrypting the pixels issued from the previous step. Simulation and experiments were carried out on medical images coded on 8 and 12 bits/pixel. The obtained results confirmed the performance and the efficiency of the proposed method, which is compliant with Digital Imaging and Communications in Medicine standards.

TL;DR: These experiments showed that all samples are polysaccharides, which are probably pectins and that molecular weight has decreased from 6,800,000 to 14,000 g/mol after 3 h of depolymerization without changing the structure.

TL;DR: The investigated reactive sites show that the same preferable sites for both electrophilic and nucleophilic attacks are detected for the sample derived from thermal treatment, allowing explaining the best performances of this adsorbent.

TL;DR: In this article, the concepts of -compatible mappings, b-coupled coincidence point and b-common coupled fixed point for mappings F, G : X × X → X, where (X, d) is a cone metric space were introduced.
Abstract: In this paper, we introduce the concepts of -compatible mappings, b-coupled coincidence point and b-common coupled fixed point for mappings F, G : X × X → X, where (X, d) is a cone metric space. We establish b-coupled coincidence and b-common coupled fixed point theorems in such spaces. The presented theorems generalize and extend several well-known comparable results in the literature, in particular the recent results of Abbas et al. [Appl. Math. Comput. 217, 195-202 (2010)]. Some examples are given to illustrate our obtained results. An application to the study of existence of solutions for a system of non-linear integral equations is also considered. 2010 Mathematics Subject Classifications: 54H25; 47H10.
