In this article, we develop numerical schemes for solving stiff reaction-diffusion equations on annuli based on Chebyshev and Fourier spectral spatial discretizations and integrating factor methods for temporal discretizations. Stiffness is resolved by treating the linear diffusion through the use of integrating factors and the nonlinear reaction term implicitly. Root locus curves provide a suc...

Fig. 1 shows the FTIR spectra of GA, AGA-PEG and AGA-PEG-ST. In the spectra of GA, the absorption peaks at 3450 cm-1, 2947 cm-1 and 1650 cm-1 are associated with hydroxyl bonds and alkene bonds of GA, respectively. The broad peak appearing between 3400 and 2500 cm-1 and the peak at 1720 cm-1 are respectively contributed to O-H bonds and carbonyl bonds in carboxylic acid. In the spectra of AGA-P...

1. The authors state that they study the impact of a pay-for-performance payment system on quality of care of hip fracture. However, they report that not all hospitals in the study are paid according the DRG payment system linked to performance (page 4). What they compared is the performance of hospitals according to different payment systems. The payment system changed only for a small part of...
