For continuous-variable systems, we introduce a measure of entanglement, the continuous variable tangle (contangle), with the purpose of quantifying the distributed (shared) entanglement in multimode, multipartite Gaussian states. This is achieved by a proper convex roof extension of the squared logarithmic negativity. We prove that the contangle satisfies the Coffman-Kundu-Wootters monogamy in...

Breast cancer is a malignant tumor of the highest morbidity and mortality in the world although the treatments of breast cancer have been improved. Furthermore, the incidence of breast cancer is increasing at an alarming rate (Parkin et al., 2006; Barron et al., 2008). Apoptosis plays an important role in the organism development and immune defense machinery (Vaux et al., 1999; Hidalgo et al., ...

In the problem of binary classification or diagnostic testing, the classification algorithm or diagnostic test produces a continuous decision variable which is compared to a critical value (or threshold). Test values above (or below) that threshold are called positive (or negative) for disease. There are two types of errors at every threshold value. The relationship between these two types is t...

The behavior of electronic states of one dimensional correlated disordered systems which are modelled by a tight binding Hamiltonian is studied analytically using the invariant measure method. The approach of Bovier is generalized to include the possibility of different site energies and nearest neighbor hopping integrals inside the correlated sites or the cluster. The process is further elabor...

In this chapter we review the characterization of entanglement in Gaus-sian states of continuous variable systems. For two-mode Gaussian states, we discuss how their bipartite entanglement can be accurately quantified in terms of the global and local amounts of mixedness, and efficiently estimated by direct measurements of the associated purities. For multimode Gaussian states endowed with loca...

The brachial artery begins as a continuation of the axillary artery and is superficial throughout its course in the arm. When it enters the cubital fossa it lies anterior to the brachialis muscle and lateral to the median nerve. In cubital fossa it lies deep to bicipital aponeurosis which separates the artery from median cubital vein. The median nerve descends along the lateral side of the prox...

This paper investigates the scope of usage of Genetic Algorithms (GA) for data hiding in digital images. The tool has been explored in this topic of research to achieve an optimal solution in multidimensional nonlinear problem of conflicting nature that exists among imperceptibility, robustness, security and payload capacity. Two spatial domain data hiding methods are proposed where GA is used ...

Coleus aromaticus Benth (Lamiaceae) is known as a must-have plant in medicinal herb garden. The plant is well known for its antimicrobial and pharmacological activities. It is also reported to possess antioxidant and food additive properties. Antioxidant activity is reported to be mainly due to rosmarinic acid, chlorogenic acid and caffeic acid. The essential oil of Coleus aromaticus has great ...

Kundu and Gupta [22] provided the analysis of Type-I hybrid censored competing risks data, when the lifetime distribution of the competing causes of failures follow exponential distribution. In this paper we consider the analysis of Type-II hybrid censored competing risks data. It is assumed that latent lifetime distributions of the competing causes of failures follow independent exponential di...
