For example, to protest cluster bombs, which kill children who find the bomblets, they staged a bomblet hunt near the last White House Easter Egg Roll.
We suppose that the fluorescence foci form when several plasmids congregate in an area of high transcriptional activity, due, for example, to a cluster of RNA polymerase molecules, and this suggests the existence of favoured locations for transcription.
One example is to cluster cities on a map, since in this case Euclidean distance represents real natural distances.
Such a neural network might be used in data mining, for example, to discover clusters of customers in a marketing data warehouse.
This study used vermilion snapper (Rhomboplites aurorubens) samples collected from commercial fisheries in the Gulf of Mexico as an example to illustrate how cluster sampling may influence the precision of estimated mean lengths and total mortality.
In the field of cluster randomized trials, several authors worked on the planning of studies through the design effect and sample size calculations and proposed extensions of classical formula, for example to account for imbalance in cluster sizes [ 20, 21].
This concept is widely used in k-means analysis, for example, to select the number of clusters being the one producing the most stable clusters.
One interesting additional feature of these systems is that physical barriers microns in dimension can be added to restrict movement of ligands, for example to impede large scale receptor clustering and thereby gain insights into its role in cell function.
In the rice blast fungus, Magnaporthe oryzae, for example, TEs were found to cluster in regions having high recombination rates and gene duplication events [ 13].
For example, we may wish to cluster objects into groups [ 37], put objects into order [ 38] or discover specific patterns of connectivity within subgroups [ 39- 42].
