When searching borne online, its meaning says past of bear. When reading a paper, it states: “These findings should be borne in mind by designers”. Contextually it sounds like designers should keep it in mind, but is there a different meaning or emphasis that this phrasing creates?
The past participle implies that the action, a learning process, should be completed, which implies that the idea shall become innert knowledge, whereas bear in mind rather sounds like the burden of permanently avoiding to forget the idea.
The difference is minicule, if the later is the path to the former. As far as I understand, it simply means “know that …” or even “appreciate” (in the sense that value appreciates, “may grow and improve”; Cp *Ger Bürde; Würde “honour, responsibility; dignity”).
The difference to keep in mind is regional, as @minty points out in the comments.
