That the material in the manuscript has been acquired according to modern ethical standards and does not contain material copied from anyone else without their written permission.5. That all material which derives from prior work, including from the same authors, is properly attributed to the prior publication by proper citation.6. That the manuscript will be maintained on the servers of the Journal and held to be a valid publication by the Journal only as long as all statements in these principles remain true.7. That if any of the statements above ceases to be true the authors have a duty to notify the journal as soon as possible so that the manuscript can be withdrawn.
