The only reason given for rejection by the editorial staff was "Unfortunately, the topic covered in your manuscript is out of our editorial intentions." Since the journal claims a very broad range of topics of interest, (including mathematical modelling, which my article was about), I have difficulty understanding this basis for rejection. I sense that the journal leans towards the interests of the editors, rather than sticking to a stated field of interest.
Still, the journal process was speedy and I would consider submitting less technical papers to this journal (to see if I am still out of their editorial interests, if for nothing else).
