Dear Steve, We agree that it is important to send as soon as possible this article. May be, we develop these comments later and we write another article! Thanks for the changes at the acknowledgements! We wish you a nice vacation!!! Sincerely yours, Alexandru Jipa Calin Besliu Sorin Zgura Catalin Ristea On Fri, 3 Aug 2001, Stephen J.
