I've been seeing both of these constructions all around, and I'd like to know if there is any rule that controls the usage of this expression.
For what I've read, it seems to me that "Bear something in mind" is used when that something is short, or a single word, like "Bearing this in mind we have that..."
On the other hand, "Bear in mind something" seems to be used when that something in longer, or even just longer than a single word, like "Bearing in mind both of those previous things...".
Any confirmation on this? What would you use if you are referring to an annotation? (e.g. "Bearing  in mind..." or "Bearing in mind theorems  and ...").
