Efficient variable mesh techniques to solve interior layer problems
… to solve such singularly perturbed TPBVPs with variable diffusion coefficients. The overall approach is further extended to parabolic singularly perturbed problems having constant as well as variable diffusion coefficients.

Novel Invariant Features of the US Stock Market
… on both time and on the current price. Recently, variable-diffusion models, which account for these dependencies, have been proposed. Here we present a model for the US stock market and investigate its first-passage-time distribution. For a Wiener process it has a single peak, while that for …

High Accuracy Fitted Operator Methods for Solving Interior Layer Problems
… on introducing a fitting factor along with the diffusion coefficient or by using principles of the non-standard finite difference methods. The FOFDMs based on the latter idea, are easy to construct and they are extendible to solve partial differential equations (PDEs) and their systems. Noting …

Oxygen control of nitrogen fixation in Frankia and Coriaria arborea
… are due to an apparent increase in nodule diffusion resistance which has also been observed in legumes. Defoliation of Coriaria also caused a decline in nitrogenase and respiratory activity associated with an apparent increase in nodule diffusion resistance although the effect was delayed …
