In the third and fourth exercises, students learned two different techniques to construct phylogenetic trees by hand ("base-to-tips" and "tips-to-base"), using the information contained in character-by-taxon matrices and extant outgroups as reference taxa.
The purpose of the paper is to design and test neural network structures and mechanisms for making use of the information that is contained in the character strings for more correct recognition of the characters constituting these strings.
The file character_haplotypes contains a listing of the SNPs or PCR-RFLPs contained in each character haplotype, and the file genome_groups gives the associated genome groups.
He was so uncharacteristically soft-spoken and concise that many in the courtroom had to strain to hear him, and some of his answers could have been contained in 140-character posts on Twitter.
Granted, Twitter's information is contained in 140 characters, so the depth of the information is slightly less intrusive.
The fact that the entire story (such as it was then) could be contained in 140 characters helped, of course.
Neighbor-joining [ 1] or other improved distance methods, e.g., WEIGHBOR [ 2], BIONJ [ 3], FASTME [ 4] and a further approach considering maximum-likelihood estimated triplets of sequences [ 5], are relatively fast (O(n) for n taxa), but first reduce the information contained in the characters to a matrix of distances.
To calculate a distance matrix from the genome group data, first, each genome group was weighted by the number of SNPs or the number of PCR primers (for PCR-RFLP) contained in the associated character haplotype.
Of course, while not every artwork can be contained in under 140 characters, it's a social experiment that has the added benefit of introducing many to the longstanding, eternally human practice of thinking about art.
Historical views of the Irish people are contained in The Irish, a Character Study (1949; rev. ed. 1969) and An Irish Journey (1940).
Variable/uncertain characters contained in the initial multiple sequence alignments cause strong artefacts in the resulting phylogenetic trees, especially for BioNJ and MP trees (see Tables 2, 3,and 4).
