The estimated cluster configurations can be post-processed in order to identify differentially expressed genes and for generating gene- and sample-wise dendrograms and heatmaps. [60] DiffSplice is a method for differential expression detection and visualization, not dependent on gene annotations. This method is supported on identification of ...
A wide range of methods have been developed to assess the structure of human populations with the use of genetic data. Early studies of within and between-group genetic variation used physical phenotypes and blood groups, with modern genetic studies using genetic markers such as Alu sequences, short tandem repeat polymorphisms, and single nucleotide polymorphisms (SNPs), among others.

A worst case example of an arbitrarily badly connected community is a internally disconnected community. An internally disconnected community arises through the Louvain algorithm when a node that had been acting as a "bridge" between two groups of nodes in its community is moved to a new community, leaving the old one disconnected.
The three gene model was originally proposed in conjunction with the four gene model; [8] however, rather than the Hox cluster and the ParaHox cluster resulting from a cluster containing three genes, the Hox cluster and ParaHox cluster were as a result of single gene tandem duplication, identical genes found adjacent on the same chromosome.

Example of modularity measurement and colouring on a scale-free network. Modularity is a measure of the structure of networks or graphs which measures the strength of division of a network into modules (also called groups, clusters or communities). Networks with high modularity have dense connections between the nodes within modules but sparse ...
Germany’s manufacturing industry, for example, which has propelled its economy for decades, is on the decline. “Climate action is taking a back seat compared to industrial action, as Germany ...
Clustered standard errors assume that is block-diagonal according to the clusters in the sample, with unrestricted values in each block but zeros elsewhere. In this case, one can define X c {\displaystyle X_{c}} and Ω c {\displaystyle \Omega _{c}} as the within-block analogues of X {\displaystyle X} and Ω {\displaystyle \Omega } and derive ...
Seurat completed the painting of Bathers at Asnières in 1884, at 24 years old. He applied to the jury of the Salon of the same year to have the work exhibited there, only to be rejected. The Bathers continued to puzzle many of Seurat’s contemporaries, and the picture would only be widely acclaimed many years after the artist's death (age 31).
