In turn, papers oriented toward experimentation, numerical simulations, or applications must not simply report results without an indication of what a theoretical explanation might be. They do have to be original, multidisciplinary in nature, and of high quality. The journal would rather err on the side of publishing innovative work in which some issues are outstanding than strive for perfect completeness. Finally, clear writing is essential if the journal is to be truly multidisciplinary. Papers must be written in simple, direct, unambiguous sentences that scientists from other disciplines can follow.
Obscure prose is a good reason to reject a paper.
The Introduction in particular must be comprehensible, and the reader should be able to grasp what the main results of the paper are. The mission of the Journal of Nonlinear Science is to publish papers that augment the fundamental ways we describe, model, and predict nonlinear phenomena. Papers should make an original contribution to at least one technical area and should in addition illuminate issues beyond that area's boundaries. Even excellent papers in a narrow field of interest are not appropriate for the journal. Papers can be oriented toward theory, experimentation, algorithms, numerical simulations, or applications as long as the work is creative and sound.
