The hypothesis of preferential attachment (PA) - whereby better connected individuals make more connections - is hotly debated, particularly in the context of epidemiological networks.
In this work, we attempt to test the hypothesis of preferential attachment in social contact data directly, rather than via asymptotic power law behaviour.
The most drastic decrease in the attachment propensity was observed for the particles with the largest dimension in the 2 3 µm range which further testifies the hypothesis of the dependence of attachment on particle geometry and presence of membrane ruffles on the macrophages.
However, the positive observations of cartilage formation from our pre-clinical and clinical studies support the hypothesis that attachment of chondrocytes is a potential factor in the mechanism of action.
The fact that dysthymic participants described their relationship with therapists in terms of personal attachment rather than collaboration generates the hypothesis that they had a greater need of attachment than participants with panic disorder.
Second, another prediction generated from the hypothesis of network evolution through preferential attachment is that highly connected nodes should gain new edges at a faster rate than nodes with low connectivities.
The null hypothesis was that exposure to formative assessment material administered in two ways would have no effect on student performance in end-of-attachment assessment.
