ROBUST BALANCED OPTIMIZATION

Robust balanced optimization

An instance of a balanced optimization problem with vector costs consists of a ground set X, a cost-vector for every element of Matte Paste X, and a system of feasible subsets over X.The goal is to find a feasible subset that minimizes the so-called imbalance of values in every coordinate of the underlying vector costs.Balanced optimization problem

Hormone therapy with tamoxifen reduces plasma levels of NT-B-type natriuretic peptide but does not change ventricular ejection fraction after chemotherapy in women with breast cancer

The objective of this study was to evaluate the effect of tamoxifen on the plasma concentration of NT-pro-B-type natriuretic peptide (NT-proBNP) in women undergoing chemotherapy for breast cancer and to correlate changes in NT-proBNP with the left ventricular ejection fraction (LVEF).Over a period of 12 months, we followed 60 women with a diagnosis
