Regular path expression is one of the core components of XML query languages, and several approaches to evaluating regular path expressions have been proposed. In this paper, a new path expression evaluation approach, extent join, is proposed to compute both parent-children (‘/’) and ancestor-descendent (‘//’) connectors between path steps. Furthermore, two path expression optimization rules, p...

The goal of this paper is to present the implementation of a Radial Basis Function neural network with built-in knowledge to recognize hand-written characters. The neural network includes in its architecture gates controlled by an attraction/repulsion system of coefficients. These coefficients are derived from a preprocessing stage which groups the characters according to their ascendant, centr...

We give a complete solution for the reduced Gromov-Witten theory of resolved surface singularities of type An, for any genus, with arbitrary descendent insertions. We also present a partial evaluation of the T -equivariant relative Gromov-Witten theory of the threefold An × P 1 which, under a nondegeneracy hypothesis, yields a complete solution for the theory. The results given here allow compa...

We introduce and study generalized R\'enyi entropies defined through the traces of products ${\rm Tr}_B (|\Psi_i\rangle\langle \Psi_j|)$ where $|\Psi_i\rangle$ are eigenstates a two-dimensional conformal field theory (CFT). When $|\Psi_i\rangle=|\Psi_j\rangle$ these objects reduce to standard CFT. Exploiting path integral formalism, we show that second equivalent four-point correlators. then fo...

ABSTRACT: This article deals with the engaged writing of prose writer, poet, translator, and Professor John Keene. The Black North-American author clashes political struggles, for he seeks to rewrite history as a literary witness, bringing assessments, evaluations, social issues bygone ages – their following outcome in present. Keene’s historical approach critical attitude uphold line his award...
