In this work, the stability and electronic structure of zigzag double-walled silicon carbide nanotubes (DWSiCNTs) (6,0)@(n,0) (with n=11-17) were investigated by using ab initio Van der Waals density functional. By calculating the formation energy and the binding energy of each double walled nanotube, the best interwall distance for the outer nanotube was indicated. The results revealed that (1...

The purpose of this paper is to study the definition of edit distances with convex gap weights for trees. In the special case of strings, this problem has yield to the definition of classical solutions: Galil and Giancarlo produced in [2] an algorithm in O(n log(n)), for example. For trees, standart edit distance algorithms – [7] or more recently [4] with a O(n log(n))) solution – are concerned...
