DOI: 10.1371/journal.pone.0264570
Abstract: Myocardial ischemia occurs when blood flow to the heart is reduced, preventing the heart muscle from receiving enough oxygen required for survival. Several anatomical and electrophysiological changes occur at the ischemic core (IC) and border… read more here.

Convergence Ball and Complex Geometry of an Iteration Function of Higher Order
Sign Up to like & getrecommendations! Published in 2018 at "Mathematics"
DOI: 10.3390/math7010028
Abstract: Higher-order derivatives are used to determine the convergence order of iterative methods. However, such derivatives are not present in the formulas. Therefore, the assumptions on the higher-order derivatives of the function restrict the applicability of… read more here.
