Introduction: gender specification among the forensic dentistry and human anthropology, is mainly based on anatomic variations. Due to racial differences and environmental factors such as time of tooth extraction, osteoporosis, dietary habits, usage of dental prosthetics and periodontal diseases, there will be different results achieved. The purpose of this study is to classify the gender speci...

The almost Mathieu operator is the discrete Schrodinger Hα,β,θ on \(\ell ^2(\mathbb {Z})\) defined via \((H_{\alpha ,\beta ,\theta }f)(k) = f(k + 1) - \beta \cos {}(2\pi \alpha k \theta ) f(k)\). We derive explicit estimates for eigenvalues at edge of spectrum finite-dimensional \({H^{(n)}_{\alpha }}\). furthermore show that (properly rescaled) m-th Hermite function ϕm an approximate eigenvecto...
