In this section we periodically publish a few leading articles produced by our research; their download is free. We hope, in this way, to cut time and costs of editorial publication with advantages for us and our readers. We hope, in this way, to cut also the cultural biases related to the use of new languages to explore new interdisciplinary fields. This is also our way to solve once forever the dilemma we face: "Wich kind of journal, but us, is now going to publish such a paper?".
