A new technique for integrating experimental manipulations into text-based, synchronous dialogue is introduced. This method supports fine-grained, systematic transformation of conversational turns and the introduction of ‘artificial’ probe turns and turn sequences. It can be used to introduce manipulations that are sensitive to aspects of the local linguistic and conversational context for any ...

An efficient algorithm leading to the Fries canonical structure is presented for benzenoid hydrocarbons. This is a purely topological approach, which is based on adjacency matrices and the Hadamard procedure of matrix multiplication. The idea is presented for naphthalene, as an example. The Fries canonical-structures are also derived for anthracene, coronene, triphenylene, phenanthrene, benz[a]...

To deal with reactive sequential decision tasks, we present a learning model Clar-ion, which is a hybrid connectionist model consisting of both localist and distributed representations, based on the two-level approach proposed in Sun (1995). The model learns and utilizes procedural and declarative knowledge, tapping into the synergy of the two types of processes. It uniies neural, reinforcement...

The degree of -electron (de)localization and aromaticity of a series of polybenzenoid hydrocarbons (PBHs) has been analyzed through the π-contribution to the electron localization function (ELFπ), calculated at the B3LYP/6-311G(d,p) hybrid density functional theory level. The extent of -electron delocalization in the various hexagons of a PBH was determined through analysis of the bifurcation...

El término ‘utopía’ ha sido empleado por diversas corrientes e instituciones, entre ellas, la vida religiosa, para dar cuenta de ideas que movilizan sus proyectos mundo. La pesquisa humanista y teológica en el continente latinoamericano no abordado se manera suficiente relación utopía religiosa. Esta investigación busca determinar una textual contextual del uso (presencia ausencia) las publicac...
