It has been suggested that the scale-free properties of biological networks may in part be due to a model of preferential attachment by means of gene duplication, whereby new nodes preferentially attach to existing highly connected nodes.
To our knowledge, this is the most successful extrapolation of a model of bacterial attachment based upon molecular descriptors to a sample set of polymers.
Interestingly, HGT genes are more likely to be connected to Core genes than expected by chance, which suggest a model of differential attachment in the expansion of cellular networks.
Such a model of preferential attachment has previously been proposed to explain the growth of protein interaction networks in S. cerevisiae [ 20, 50, 51] and was also suggested recently for E. coli [ 52]; however it has remained mostly unproven since it was difficult to trace back the evolution history of protein networks.
Some evidence from longitudinal research suggests that there are distinct models of attachment for the mother and the father, respectively, and that such distinct models do not coalesce into a single model of attachment until late adolescence [15].
Jagged-1 was not robustly expressed in a model of delayed aortic attachment and delayed initiation of blood flow.
Early relationships with parents, such as parental rearing styles and household atmosphere, impact the formation of an internal working model of attachment [ 16].
It is a fourteen item scale developed as a screening tool to identify potential problems in the early mother-infant relationship; particularly in a mother's working model of attachment.
We analyzed a model of delayed CA stem attachment to the aorta, Isl1 heterozygosity (Cai et al., 2008a), which postpones the initiation of blood flow (Chen et al., 2014a).
The working model of attachment a child with this type of parent forms is that others are dangerous and will hurt you, but that you desperately need them.
