A suffix tree or not a suffix tree? [PDF]

open access: yesJournal of Discrete Algorithms, 2015
In this paper we study the structure of suffix trees. Given an unlabeled tree $ $ on $n$ nodes and suffix links of its internal nodes, we ask the question "Is $ $ a suffix tree?", i.e., is there a string $S$ whose suffix tree has the same topological structure as $ $?

Tree compression with top trees [PDF]

open access: yesInformation and Computation, 2013
We introduce a new compression scheme for labeled trees based on top trees. Our compression scheme is the first to simultaneously take advantage of internal repeats in the tree (as opposed to the classical DAG compression that only exploits rooted subtree repeats) while also supporting fast navigational queries directly on the compressed representation.

Pairs of trees in tree–tree triangulations

open access: yesDiscrete Mathematics, 2007
AbstractA triangulation T of a compact 2-manifold is said to be a tree–tree triangulation if the graph of T can be partitioned into two induced trees. Hence each tree–tree triangulation is a triangulation of the 2-sphere. Recognizing tree–tree triangulations among all simple spherical ones can be seen to be an NP-complete problem.

Comparative analysis of flavonoids, polyphenols and volatiles in roots, stems and leaves of five mangroves [PDF]

open access: yesPeerJ, 2023
Mangrove plants contain a variety of secondary metabolites, including flavonoids, polyphenols, and volatiles, which are important for their survival and adaptation to the coastal environment, as well as for producing bioactive compounds.

FastTree 2 – Approximately Maximum-Likelihood Trees for Large Alignments

open access: yesPLoS ONE, 2010
Background We recently described FastTree, a tool for inferring phylogenies for alignments with up to hundreds of thousands of sequences. Here, we describe improvements to FastTree that improve its accuracy without sacrificing scalability.
