How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Computation-based mathematical models of tissue indentation are capable of predicting the distribution of forces and mechanical properties of soft tissues. This paper presents a three-dimensional mathematical model of anisotropic tissue indentation developed using the mechanical bidomain model. The mechanical bidomain model hypothesizes that the re...
Although there are various hypotheses that explain the pathological behavior of growth and remodeling in cardiac tissue, our understanding of how cells sense or respond to mechanical overloading conditions is not adequate to make clinical predictions. Most of the prevailing models are simplified by eliminating properties such as anisotropy, archite...
The properties of cardiac muscle are anisotropic, and the degree of anisotropy may be different in the intracellular and extracellular spaces. In the electrical bidomain model, such “unequal anisotropy ratios” of the conductivity lead to unanticipated behavior. In the mechanical bidomain model, unequal anisotropy ratios of the mechanical moduli mig...
The properties of cardiac muscle are anisotropic: they depend on direction along or across the myocardial fibers. Studying the effects of anisotropy is essential for understanding the behavior of cardiac muscle. The bidomain model represents the intracellular and extracellular spaces separately, so "unequal anisotropy ratios" means the degree of an...
Many characteristics of a star can be calculated using the method of curve of growth including its chemical abundances of the atmosphere which is able to describe the chemical composition of a star. Analysis of Fe I abundances was conducted using the method of curve of growth (COG). The spectrum of star HD26574 (Beid), in the wavelength region of 4...
