To facilitate the review process however, we strongly encourage you to incorporate the manuscript text and figures into a single pdf or Microsoft Word file. Suitably high resolution figures may be inserted within the text at appropriate positions or grouped at the end. Each figure legend should be presented on the same page as its figure. The reference list should include article titles. If providing a pdf, please number all lines. The submission system will number all lines in a Word document for you. We accept LaTeX files at the acceptance stage, but before that time please supply PDFs.
