Diffusion models have been used extensively in many applications. These models, such as those used in the financial engineering, usually contain unknown parameters which we wish to determine. One way is to use the maximum likelihood method with discrete samplings to devise statistics for unknown parameters. In general, the maximum likelihood functions for diffusion models are not available, hen...

The contact chemosensilla on the labellum of the fly are in the form of a hair housing five sensory neurons, i.e. four contact chemoreceptor cells and one mechanoreceptor neuron (Ozaki and Tominaga, 1999). Three of the four chemoreceptor cells are the sugar, salt and water receptor cells, respectively. The remaining chemoreceptor cell, traditionally called the ‘fifth cell’, has recently been pr...

assume that $mathbb{d}$ is the open unit disk. applying ozaki's conditions, we consider two classes of locally univalent, which denote by $mathcal{g}(alpha)$ and $mathcal{f}(mu)$ as follows begin{equation*}  mathcal{g}(alpha):=left{fin mathcal{a}:mathfrak{re}left( 1+frac{zf^{prime prime }(z)}{f^{prime }(z)}right)
