Step 6: An empty arrow means that the incoming and outgoing interactions occur with distinct systems.
Step 3: Two filled arrows mean that the incoming and outgoing interactions occur with the same system.
For instance, for the FNR regulon, the fraction drops to 0 at SOS 0.5, which means that no FNR outgoing interactions have associated SOS values higher than 0.5.
Since many real networks are directed, nodes are characterized by in and out-degree, giving the number of incoming and outgoing interactions.
We also consider a model of regulatory network evolution by Foster et al. [ 32], which is based on gene duplication, with incoming and outgoing interactions kept after duplication as in other models (Pinkeep and Poutkeep probabilities respectively).
The siblings were close, but Aguigui, bright and outgoing, craved more interaction.
She became more confident, animated, and outgoing in her interactions with the audience and in her choice of clothes and hairstyles.
It can be argued that the active search for interactions in outgoing workers represents an indirect measure of the workers' information needs, which is strongly phase-dependent.
We suggest that returning workers, through their interactions with outgoing workers on the trail and the expected trail-marking, are responsible for the initial establishment of a foraging process.
The observed interactions between outgoing and returning workers, and published results [9], [18], provide indirect support to the idea that the decision to return unladen to the nest, with the concomitant time savings, represents a response to the high needs for information at the beginning of a daily foraging process.
The in-duct power is then compared with noise measurements carried out in a semianechoic chamber, in order to distinguish between flow noise contributions associated with internal generation (muffler and tailpipe) and flow noise produced in the discharge process (interaction between the outgoing flow and the outside atmosphere).
