It is known that correlation-immune (CI) Boolean functions used in the framework of side-channel attacks need to have low Hamming weights. The supports CI are (equivalently) simple orthogonal arrays when their elements written as rows an array. minimum weight a function then same number In this paper, we use Rao's Bound give sufficient condition on rows, for binary array (OA) be simple. We appl...

Among the many interesting features displayed by graphene, one of the most attractive is the simplicity with which its electronic structure can be described. The study of its physical properties is significantly simplified by the linear dispersion relation of electrons in a narrow range around the Fermi level. Unfortunately, the mathematical simplicity of graphene electrons is limited only to t...
