My latest paper just received online release and is expected to get published soon in the printed version of the Journal of Aerospace Engineering. Besides being my first post-PhD journal publication, the other reason of being of certain importance is of myself being a lone author.
“The lone author has all but disappeared. In most fields outside mathematics, fewer and fewer people know enough to work and write alone.” 
“The effort and initiative required to publish alone suggests an independent and tenacious scientist — both highly desirable qualities in any researcher.”
