It is known that the nonnegativity of Li coefficients a necessary and sufficient condition for Riemann hypothesis. We show it hypothesis all are norms certain concrete functions on real line. Such conditional formulas understood as kind Weil's criterion

This paper tests a multi-factor asset pricing model that does not assume the return’s beta coefficients are constants. is done by estimating generalized arbitrage theory (GAPT) using price differences. An implication of GAPT when differences instead returns, constant. We employ adaptive (AMF) to test utilizing Groupwise Interpretable Basis Selection (GIBS) algorithm identify relevant factors fr...

Mediation models figure out how an effect occurred by hypothesizing a causal sequence. For a simple mediation model, a causal sequence is described in which an independent variable causes the mediator which sequentially causes the dependent variable. In this article, we tried to introduce to use standardized regression coefficient to the involving the simple mediation model since a standardized...

in this paper, we try to find a particular combination of wavelet shrinkage and nonlinear diffusion for noise removal in dental images. we selected the wavelet diffusion and modified its automatic threshold selection by proposing new models for speckle related modulus. the laplacian mixture model and circular symmetric laplacian mixture models were evaluated and as it could be expected, the lat...

  Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problems are co...
