JYI is an international, online journal that has been published, reviewed, and written by undergraduates since 1997. JYI is supported by the National Science Foundation, Science Magazine, the Burroughs Wellcome Fund, Science's Next Wave, and various other organizations and institutions. JYI's next issue will be published on June 1, and papers for this issue are due on or before May 1st. JYI does, however, have a rolling submissions cycle, so papers are accepted for review at any time. JYI also accepts feature articles, which are science-interest articles.
Feature articles go through a peer-review process similar to that of the research articles.
JYI will soon begin considering applications for staff positions for the upcoming academic year. We hope to hear from you. The figure above shows isocontours of the vorticity field in the initial region of a spatially developing, forced, shear layer. The formation of vortices due to the Kelvin-Helmholtz instability in the shear layer can be seen clearly in this figure. The two vortices slightly further downstream are beginning the pairing process, while the larger vortex downstream near the exit of the domain is the result of a pairing between two smaller vortices.
