Abstract: This paper proposes the novel directional selection based on the complex discrete wavelet transform (CDWT). CDWT is known as a very useful image processing method because of shift-invariant ...

Predicting adaptive phenotypic evolution depends on invariable selection gradients and on the stability of the genetic covariances between the component traits of the multivariate phenotype. We ...

When you envision a leader, what comes to mind? For most, the image is hierarchical—a figurehead at the top, making decisions that cascade down the ranks. However, a radical shift in leadership ...

Currently selection of entities on the battle field is locked to only increment/decrement an integer value. It would be nice if these were directionally informed, based on the arrangement of entities ...

I am working on foot and mouth disease virus serotype A. I estimated natural selection pressure on 1D gene by using the dN/dS ratio using datamonkey server, mainly MEME and FUBAR. I got following ...
