Copyright and Licensing

For all articles published in Gexin journals, copyright is retained by the authors. Articles are licensed under an open access Creative Commons CC BY 4.0 license, meaning that anyone may download and read the paper for free. In addition, the article may be reused and quoted provided that the original published version is cited. These conditions allow for maximum use and exposure of the work, while ensuring that the authors receive proper credit.

In exceptional circumstances, articles may be licensed differently. If you have specific condition (such as one linked to funding) that does not allow this license, please mention this to the Editorial Office of the journal at submission. Exceptions will be granted at the discretion of the publisher.

For previously published content, it is essential that prior to submission, authors obtain permission to reproduce any published material (figures, tables, text, etc.) that does not fall into the public domain, or for which they do not hold the copyright.

Permission is required for

• Your own work published by other publishers and for which you did not retain copyright.
• Substantial extracts from the work of anyone works or a series of work.
• Use of tables, graphs, charts, schemes and artworks if they are unaltered or slightly modified.
• Photographs for which you do not hold copyright.

Permission is not required for

• Reconstruction of your own table with data already published elsewhere. Please note that in this case, you must cite the source of the data in the form of either "Data from..." or "Adapted from...".
• Very short quotes are considered fair use and therefore do not require permission.
• Graphs, charts, schemes and artwork that is completely redrawn by the authors and significantly changed beyond recognition do not require permission. However, you may need to check the copyright permissions of any underlying data.

Once you have obtained permission, the copyright holder may give you instructions on the form of acknowledgement to be followed. Alternatively, we recommend following the style: “Reproduced with permission from [author], [book/journal title]; published by [publisher], [year]”.
