The power of the obtained spiking neural P systems is investigated and the modeling of gene expression in these terms is discussed. Some further extensions are mentioned, such as considering a process of decay in time of the spikes.}, url = {http://www.gcn.us.es/9BWMC/volume/12multiAlfonso.pdf}, author = {Mihai Ionescu and Gheorghe Paun and Mario J.
