Our purpose is to relate the Fokker-Planck formalism proposed by [Friedrich et al., Phys. Rev. Lett. 84, 5224 (2000)] for the distribution of stock market returns to the empirically well-established power law distribution with an exponent in the range 3− 5. We show how to use Friedrich et al.’s formalism to predict that the distribution of returns is indeed asymptotically a power law with an ex...

Background Chest X-rays are a relatively cheap investigative tool that aids in early detection of cardiopulmonary abnormalities and this translates in better mortality outcomes and reduced length of stay (Henschke, Yankelevitz et al. 1996). According to a study done in Mulago general ICU by Ssemogerere et al, more than half of admitted patients needed a form of respiratory support especially me...

Existence of fixed point in orthogonal metric spaces has been initiated recently by Eshaghi and et al. [On orthogonal sets and Banach fixed Point theorem, Fixed Point Theory, in press]. In this paper, we introduce the notion of the strongly orthogonal sets and prove a genuine generalization of Banach' fixed point theorem and Walter's theorem. Also, we give an example showing that our main theor...

Theories guide the practice and research of distance education. Traditionally, theories of distance education have been derived from classical European or American models based on correspondence study. Recently, telecommunications systems have significantly altered the practice of distance education in the United States and have produced a uniquely American approach to this field. This has crea...

Objective: The increasing importance of the movement of positive psychology has led scientific research to explore and measure the optimal human performance or flourishing. Many researchers believe that the components of flourishing are different in sociocultural contexts, and culture is the primary factor affecting the optimal human performance. Therefore, in this study, we aimed to develop an...
