Please note that all authors must sign the required publication forms and any changes in authorship must be communicated to the editorial office in a letter signed by all authors.

If the matter cannot be resolved satisfactorily, it could lead to our contacting officials at your institution. Therefore, we recommend you give this matter your close and immediate attention.
