Dear Editor-in-Chief,\\

Since we found that we could answer all the questions from the two reviewers of our rejected paper submitted under the manuscript ID SPL-14503-2013, we have rebranded and rewritten our paper to address their concerns.\\ 

For this resubmission, according to your policy, we would like to request the new review undertaken by the same associated editor Dr. Jerónimo Arenas-García.\\

Thank you for your help,\\ 

Best Regards,\\

The authors
