background: although percutaneous coronary intervention (pci) is an excellent therapy for coronary artery disease, there is a paucity of information on the efficacy of pci in improving diastolic function, especially in iran. because of the high prevalence of left diastolic dysfunction in coronary artery disease patients and its probable progression to heart failure, an evaluation of the role of...

In this article, we apply the Multiquadric radial basis function (RBF) interpo-lation method for nding the numerical approximation of traveling wave solu-tions of the Kawahara equation. The scheme is based on the Crank-Nicolsonformulation for space derivative. The performance of the method is shown innumerical examples.

On the question of wave-particle duality, from historic Bohr-Einstein debates a century ago, to this day, view expressed in Niels Bohr’s Complementarity Principle has become well established, confirmed by numerous experiments: If observation is for wave nature, then particle changes wave, and if remains particle. However, recently been challenged. With proof based on definition function, it sho...
