It is well established that the conservation of protein structure during evolution constrains sequence divergence. The conservation of certain physicochemical environments to preserve protein folds and then the biological ...

The taxonomic status of the three nototheniids, Lepidonotothen squamifrons, L. larseni and Gobionotothen marionensis from different localities in the Southern Ocean is re-evaluated at the DNA level. DNA sequence divergences ...

Tomato ringspot virus (ToRSV) has been detected in Chile, causing economically important diseases in a wide range of hosts. A ToRSV isolate was obtained from raspberry cv Heritage (Rasp-CL) showing leaf yellowing and ...

A standard engineering procedure for approximating the solutions of an infinite-dimensional inverse problem of the form Ax = y, where A is a given compact linear operator on a Hilbert space X and y is the given data, is ...

Entropy based measures have been frequently used in symbolic sequence analysis. A symmetrized and smoothed form of Kullback-Leibler divergence or relative entropy, the Jensen-Shannon divergence (JSD), is of particular ...

The Neotropical bat genus Chiroderma consists of five recognized species. This study uses DNA-sequence variation of the mitochondrial cytochrome b gene to infer the phylogenetic relationships within Chiroderma. Phylogenetic ...
