摘要

Research Articles present a major scientific advance and often require additional text and figures to adequately document the findings. Articles that need more than 4500 words and 6 figures or tables will be published in full online with only an extended abstract in print. Those articles whose significance can be demonstrated in fewer words and figures will be published in full online and in print. Requests for the longer online format should provide justification for the additional presentation length. All Research Articles include an abstract, an introduction, and sections with brief subheads.
