WebOct 15, 2024 · Clusters were identified using automatic module detection via dynamic tree cutting algorithm, using minimum module size 30. Cluster “eigengene” or metabolite, in this case, is defined as the first principal component of the metabolite abundances across replicates of each sample point ( Langfelder and Horvath, 2008 ).

WebAbstract. A data structure is proposed to maintain a collection of vertex-disjoint trees under a sequence of two kinds of operations: a link operation that combines two trees into one by adding an edge, and a cut operation that divides one tree into two by deleting an edge. Each operation requires O (log n) time. Web3 Mergeable Trees via Dynamic Trees The dynamic tree (or link-cut tree) data structure of Sleator and Tarjan [21, 22] represents a forest to which arcs can be added (by the link operation) and removed (by the cut operation). These operations can happen in any order, as long as the existing arcs de ne a forest. The primary goal of the data ...
