In this example, the age-stratified data are distributed using the same lifetime assumptions applied earlier.
When methodological guidelines are followed and cost-effectiveness results are reported over the lifetime, assumptions inevitably have to be made.
The available load data are representative for the whole economic lifetime: This assumption is more of a data constraint than a willingly chosen assumption, as for most remote areas, no empiric annual load profile is available.
The lifetime treatment assumption is consequently a conservative one.
We carry with us a lifetime of assumptions about cars, and those assumptions can limit our perception of new opportunities.
For the microgrid shown in Fig. 1, we consider minimizing the present value of the costs occurring within the project lifetime, with the assumption that the load and the wind remain the same among the different years.
In the context of lifetime risk estimation this assumption is no longer valid since a subset of the control population might eventually develop the disease.
The simplest approach is global binning, which involves binning all the detected photons from a region of interest (ROI) and fitting the composite signal to, for example, a double-exponential decay model, to determine the fluorescence lifetime components under the assumption that the lifetimes are invariant across the ROI.
For a fluorophore in the medium that has a mono-exponential decay with lifetime τ, under the assumption of equal absorption and scattering coefficients at λ x and λ m, the fluorescence signals can be simulated by convolving the temporal signals generated at the excitation wavelength by the exponential time decay of the fluorophore given by exp −t/τ).
Different smoking habits in the general population (from which we derived our lung cancer mortality rates), compared with the cohorts (from which we derived our exposure response function) would not affect our estimates of excess lifetime mortality if the assumption of no effect modification by smoking were correct.
