Submission
Supply all supplementary material in standard file formats.To accommodate user downloads, please keep in mind that larger-sized files may require very long download times and that some users may experience other problems during downloading.

Audio, Video, and Animations

Text and Presentations
Submit your material in PDF format; .doc or .ppt files are not suitable for long-term viability.A collection of figures may also be combined in a PDF file.

Spreadsheets
Spreadsheets should be converted to PDF if no interaction with the data is intended. If the readers should be encouraged to make their own calculations, spreadsheets should be submitted as .xls files (MS Excel).

Specialized Formats
Specialized format such as .pdb (chemical), .wrl (VRML), .nb (Mathematica notebook), and .tex can also be supplied.

Collecting Multiple Files
It is possible to collect multiple files in a .zip or .gz file.

Numbering
If supplying any supplementary material, the text must make specific mention of the material as a citation, similar to that of figures and tables (e.g., ". . . as shown in Animation 3").Name your files accordingly, e.g., Animation3.mpg.

Captions
For each supplementary material, please supply a concise caption describing the content of the file.

Processing of supplementary files
Electronic supplementary material will be published as received from the author without any conversion, editing, or reformatting.
