Same-call interactions (bottom left to top right diagonal in Figure 5B) were not more common than interactions between different call types.
Within these complexes, the presence of direct exchange between paramagnetic ligand and metal units can result in exceptionally strong magnetic coupling, much stronger in fact than more common superexchange interactions.
The two human structures have the TCR in an off-diagonal mode of interaction, while the mouse structure is in the more common diagonal interaction.
This result indicates that, for the transcription of miRNAs, activation interactions are more common than repression interactions, a finding which is consistent with the observation for the transcription of protein-coding genes [ 38].
The literature surrounding plant and animal genetics indicates that fan-shaped interactions generally are more common than crossover interactions (Lynch and Walsh 1998; Mather and Jinks 1982).
In natural aquatic microcosms, facilitative interactions among detritivorous species are generally more common than competitive interactions [40] [43].
While having a wireless network organized according to the expected node interactions will allow routing protocols to perform more efficiently, less common interactions between different clusters must also be handled.
This work found that 'between pathway' interactions were the more common class, perhaps because negative interactions typically reflect redundant behavior that is more likely to be found between parallel biochemical pathways than within a single pathway focusing on a given biochemical function.
Recent work also shows that non-reciprocity is more common in human social interactions that would be expected from traditional social and anthropological theory pointing to the "norm" of reciprocity [20].
