Molecular phylogenetics of an aquatic plant lineage, Potamogetonaceae
Autor: Brian R. Keener, Jan De Laet, Lone Aagesen, Charlotte Lindqvist, Victor A. Albert, Robert R. Haynes
Publikováno v: Cladistics : the international journal of the Willi Hennig SocietyReferences. 22(6)
Like most aquatic plants, the pondweeds (Potamogetonaceae) are among the most phenotypically reduced and plastic of all angiosperms. As such, hypotheses of structural homology present difficulties for morphological phylogenetic reconstruction. We use

A reconsideration of inapplicable characters, and an approximation with step-matrix recoding
Autor: Jan De Laet, Duniesky Ríos-Tamayo, Pablo A. Goloboff, Claudia A. Szumik
Publikováno v: Cladistics : the international journal of the Willi Hennig SocietyReferences. 37(5)
Evidence for phylogenetic analysis comes in the form of observed similarities, and trees are selected to minimize the number of similarities that cannot be accounted for by homology (homoplasies). Thus, the classical argument for parsimony directly l

A note on Brazeau et al.'s (2017) algorithm for characters with inapplicable data, illustrated with an analysis of their Fig. 3d using anagallis, a program for parsimony analysis of character hierarchies
Autor: Jan De Laet
Brazeau et al. (2017) recently published a paper with a single-character algorithm to calculate the score of a character with inapplicable data on a tree, aiming to maximize homology in such characters. In this note, I show by example (using their Fi

Anagallis, a program for parsimony analysis of character hierarchies. Version 1.03, 8 September 2020. Program and documentation
Autor: Jan De Laet
Anagallis is a computer program for parsimony analysis of character hierarchies that provides a solution to the well-known problem of inapplicable data by maximizing homology in such hierarchies. This file is a pdf-version of a dump of the built-in d

Parsimony analysis of unaligned sequence data: maximization of homology and minimization of homoplasy, not minimization of operationally defined total cost or minimization of equally weighted transformations
Autor: Jan De Laet
Wheeler (2012) stated that minimization of ad hoc hypotheses as emphasized by Farris (1983) always leads to a preference for trivial optimizations when analysing unaligned sequence data, leaving no basis for tree choice. That is not correct. Farris's

Parsimony and the problem of inapplicables in sequence data
Autor: Jan De Laet
© Oxford University Press 2005. All rights reserved. Problems can arise in parsimony analyses when data sets contain characters that are not applicable across all terminals. Examples of such characters are tail colour when some terminals lack tails,

Data decisiveness, missing entries, and the DD index
Autor: Jan De Laet, Erik Smets
Publikováno v: ResearcherID
The decisiveness of a data set has been defined as the degree to which all possible dichotomous trees for that data set differ in length, and the DD statistic (the data decisiveness index) has been proposed to measure this degree. In this paper, we f

52.2: Long Life UHP Lamps for Consumer Applications
Autor: Holger Moench, Jan de Laet, Ulrich Hechtfischer, Ulrich Niemann, Hermann Giese
Publikováno v: SID Symposium Digest of Technical Papers. 36:1600
UHP-lamp based rear projection systems capture the market for large screens. This requires new generations of reliable lamps with very long lifetimes at powers higher than 100W. Sophisticated modelling of plasma, burner and high temperature chemistry
