Time derivatives along curve

Figure 2 Intravitreal triamcinolone concentrations after a single intravitreal triamcinolone acetonide injection in five eyes. Concentration-time data for each vitreous sample for all patients are shown along with two-compartment model-derived pharmacokinetic curves.

Hysteresis and elastic after-working in the condensed films. As a rule, if the compression on the films is reduced, they expand nearly along the original curve of compression, with but little time-lag. In the neighbourhood of the transition temperature of the urea derivatives, however, a decided difference between the curve of compression and of decompression was found (/). 

Similar physical arguments permit us to derive the adjoint boundary conditions. The transversality conditions are easily found by noting that perturbations in the form of added xenon and added iodine (with importance Xf and respectively) at the final time in the optimal problem would be expected to lead to a change in the cost function. Yet a particular linear combination of such perturbations, bXf and SIj-, would not lead to an increase if the endpoint of the trajectory merely moved along the target curve no further change would be required. That is, if the cost increase vanishes,...
