A new wavelength interval selection procedure, moving window partial least-squares regression (MWPLSR), is proposed for multicomponent spectral analysis. This procedure builds a series of PLS models in a window that moves over the whole spectral region and then locates useful spectral intervals in terms of the least complexity of PLS models reaching a(More)
Normal adult human bladder obtained at cystoscopy has been maintained in long-term organ culture. Several media were tested for their ability to maintain viability and normal tissue morphology. The optimum medium was Ham's F-12 nutrient mixture, supplemented with 10% fetal calf serum, hydrocortisone (1 microgram/ml), and FeSO4, (0.45 microgram/ml). During(More)
