In the financial world, importance of “downside risk” and “higher moments” has been emphasized, predominantly in developing countries such as Pakistan, for a substantial period. Consequently, this study tests four models suitable capital asset pricing model. These are CAPM’s beta, beta replaced by skewness (gamma), with gamma, downside CAPM (DCAPM), gamma. The problems high correlation between ...

In this paper, we present new extensions of incomplete gamma, beta, Gauss hypergeometric, confluent hypergeometric function and Appell-Lauricella functions, by using the extended Bessel due to Boudjelkha [?]. Some recurrence relations, transformation formulas, Mellin transform integral representations are obtained for these generalizations. Further, an extension Riemann-Liouville fractional deri...

We improve several results recently established by Dragomir et al. in (2000) for the Gamma and Beta functions. All we need is some clever applications of classical inequalities.

in this paper, the numerical technique based on hybrid bernoulli and block-pulse functions has been developed to approximate the solution of system of linear volterra integral equations. system of volterra integral equations arose in many physical problems such as elastodynamic, quasi-static visco-elasticity and magneto-electro-elastic dynamic problems. these functions are formed by the hybridi...

Background: Lack of farmers’ knowledge, illegal production and import, and economical situation are the main reasons for non-authorized usage. In this study, one of the major center of cucumber cultivation at south west of Iran, Darreh shahr City in Ilam Province were studied for non-authorized pesticides usage, which health authorities and national standard organization do not recommend....

Mating pheromones of Saccharomyces cerevisiae control both signal transduction events and changes in cell shape. The G beta gamma complex of the pheromone receptor-coupled G protein activates the signal transduction pathway, leading to transcriptional induction and cell cycle arrest, but how pheromone-dependent signalling leads to cell shape changes is unclear. We used a two-hybrid system to se...

Using the Bernstein theorem we give a simple proof of complete monotonicity three parameter generalized Mittag-Leffler function $E_{\alpha, \beta}^{\gamma}(-x)$ for $x \geq 0$ and suitably adjusted parameters $\alpha$, $\beta$ $\gamma$

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

The expression of the matrix-degrading enzymes collagenase and stromelysin is modulated by a variety of biologic and pharmacologic agents. IFN-gamma has potent effects on metalloproteinase production and therefore may play an important role in preventing excessive connective tissue degradation during inflammation and repair. We investigated the mechanisms of collagenase and stromelysin regulati...

The conventional quark mass is not continuous at thresholds. In this paper, we derive matchinginvariant masses which are everywhere. They expanded as an obvious function of the logarithmic Lambda scaled energy. expansion coefficients related to original gamma and beta functions, with concretization four loop level. results show that new expressions for converge indeed much faster.
