Changes in myocardial elasticity derived from in-vivo cardiac MRI in a swine model of ischemic heart failure [PDF]

open access: yesScientific Reports
The progression of chronic heart failure after myocardial infarction (MI) is traditionally evaluated by serial changes in left ventricular (LV) ejection fraction (EF), a measure of systolic function.

Application of a Generalized Secant Method to Nonlinear Equations with Complex Roots

open access: yesAxioms, 2021
The secant method is a very effective numerical procedure used for solving nonlinear equations of the form f(x)=0. In a recent work (A. Sidi, Generalization of the secant method for nonlinear equations. Appl. Math. E-Notes, 8:115–123, 2008), we presented

Extending the solvability of equations using secant-type methods in Banach space

open access: yesJournal of Numerical Analysis and Approximation Theory, 2021
We extend the solvability of equations dened on a Banach space using numerically ecient secant-type methods. The convergence domain of these methods is enlarged using our new idea of restricted convergence region.

Study on the size effect of the secant modulus of rocks containing multiple parallel joints

open access: yesFrontiers in Materials, 2022
The secant modulus of the rock reflects the stiffness of the rock and the ability to resist deformation. There are significant differences in the secant modulus of the rock due to the different numbers of joints in the rock and the change in rock size ...
