Production of Reactive Oxygen Species and Its Implication in Human Diseases

Abstract: Reactive oxygen species (ROS) are chemical molecules with one unpaired electron and mostly derived from molecular oxygen. It is produced in all the mammalian system by various exogenous and endogenous sources. Mitochondria are major sources of ROS production and they are produced as a respiratory by-product. The main sites of superoxide radical production in the respiratory chain are complexes III and I; however, other mitochondrial enzymes are also involved in the production of ROS. Because of the presence of one unpaired electron, ROS is highly reactive, and it may cause oxidative damage to the biomolecules and cell organelles and hence may affect the cellular physiology and their survivability.

Detection of copy-move forgery using wavelet decomposition

Abstract: Nowadays, it is possible to copy and paste important information from one image to other or within the same image, without leaving any clues of tampering. Hence, the authenticity of digital images can no longer be taken for granted. There is a requirement for the implementation of new powerful and efficient algorithms for forgery detection of a tampered images. In this paper, we have proposed a new computationally efficient algorithm for copy-move forgery detection of an image using wavelet decomposition method. The proposed method achieves an accuracy of 86.67 % within a small processing time.

Lower- and Higher-Order Nonclassical Properties of Photon Added and Subtracted Displaced Fock States

Abstract: Nonclassical properties of photon added and subtracted displaced Fock states have been studied using various witnesses of lower- and higher-order nonclassicality. Compact analytic expressions are obtained for the nonclassicality witnesses. Using those expressions, it is established that these states and the states that can be obtained as their limiting cases (except coherent states) are highly nonclassical as they show the existence of lower- and higher-order antibunching and sub-Poissonian photon statistics, in addition to the nonclassical features revealed through the Mandel $Q_M$ parameter, zeros of Q function, Klyshko's criterion, and Agarwal-Tara criterion. Further, some comparison between the nonclassicality of photon added and subtracted displaced Fock states have been performed using witnesses of nonclassicality. This has established that between the two types of non-Gaussianity inducing operations (i.e., photon addition and subtraction) used here, photon addition influences the nonclassical properties more strongly. Further, optical designs for the generation of photon added and subtracted displaced Fock states from squeezed vacuum state have also been proposed.
