Determining what sets of trees can be the clique trees of a chordal graph
(Springer, 2012-06-22)
Chordal graphs have characteristic tree representations, the clique trees. The problems of finding one or enumerating them have already been solved in a satisfactory way. In this paper, the following related problem is ...
Comparing trees characteristic to chordal and dually chordal graphs
(Elsevier, 2011-08-01)
Chordal and dually chordal graphs possess characteristic tree representations, namely, clique trees and compatible trees, respectively. The following problem is studied: given a chordal graph G, it has to be determined if ...
Rate of tree carbon accumulation increases continuously with tree size
(Nature Publishing Group, 2014-03)
Forests are major components of the global carbon cycle, providing substantial feedback to atmospheric greenhouse gas concentrations. Our ability to understand and predict changes in the forest carbon cycle—particularly ...
Counting of spanning trees of a complete graph
(Universidade Federal de Santa Maria, 2018)
Pasture trees in tropical México: the effect of soil nutrients on seedling growth

Adaptation of the closest tree method for a two state quartet to Jukes-Cantor tripod trees
(Centro de Investigaciones en Matemática Pura y Aplicada (CIMPA) y Escuela de Matemática, San José, Costa Rica., 2023)
Natural Language Explanation Model for Decision Trees
(Institute of Physics Publishing, 2020-01-07)
This study describes a model of explanations in natural language for classification decision trees. The explanations include global aspects of the classifier and local aspects of the classification of a particular instance. ...
Neighborhood inclusion posets and tree representations for chordal and dually chordal graphs
(Elsevier Science, 2020-07)
This paper is motivated by the following problem: given the family ofclique trees of a chordal graph G, determine whether it is also the family of compatible trees of some dually chordal graph H. A relationship isestablished ...
Amazonian várzea forests: adaptive strategies of trees as tools for forest management
(Universidad Nacional Agraria La Molina. Departamento Académico de Biología, 2004)
Accuracy and Precision of Species Trees: Effects of Locus, Individual, and Base Pair Sampling on Inference of Species Trees in Lizards of the Liolaemus darwinii Group (Squamata, Liolaemidae)
(Oxford University Press, 2012-03)
Molecular phylogenetics has entered a new era in which species trees are estimated from a collection of gene trees using methods that accommodate their heterogeneity and discordance with the species tree. Empirical evaluation ...
