The theory of neuronal firing in Stein’s model is outlined as well as the corresponding theory for a diffusion approximation which has the same first two infinitesimal moments. The diffusion approximation is derived from the discontinuous model in the limit of large input frequencies and small postsynaptic potential amplitudes. A comparison of the calculated mean interspike intervals is made fo...

The present study was conducted to investigate the effectiveness of deductive instruction of grammar with input enhancement and without using input enhancement. It also explored the effectiveness of inductive instruction of grammar with input enhancement and without input enhancement among Iranian EFL learners. The participants were female intermediate-level students who were studying English a...

The theory of evolutionary variational inequalities fits very well in a lot of optimization problems, like for example the dynamic oligopolistic market equilibrium problem that we describe in this paper. But here, the authors analyze the behavior of control policies whose aim is to regulate the exportation through the adjustments of supply taxes or incentives on the firms. This is considered as...
