This study aims to determine whether IGFBP2 is elevated in blood samples of lung cancer patients and whether its level is associated with clinical outcomes. METHODOLOGY/PRINCIPAL FINDINGS Plasma IGFBP2 levels were determined blindly by enzyme-linked immunosorbent(More)
In this paper, the existence of step-like contrast structure for a class of singularly perturbed optimal control problem is shown by the contrast structure theory. By means of direct scheme of boundary function method, we construct the uniformly valid asymptotic solution for the singularly perturbed optimal control problem. Finally , an example is presented(More)
