Uncovering latent structure in valued graphs: A variational approach [PDF]

open access: yes, 2010
As more and more network-structured data sets are available, the statistical analysis of valued graphs has become common place. Looking for a latent structure is one of the many strategies used to better understand the behavior of a network.

First steps towards a floral structural characterization of the major rosid subclades [PDF]

open access: yes, 2018
A survey of our own comparative studies on several larger clades of rosids and over 1400 original publications on rosid flowers shows that floral structural features support to various degrees the supraordinal relationships in rosids proposed by ...

Floral structure and systematics in four orders of rosids, including a broad survey of floral mucilage cells [PDF]

open access: yes, 2018
Phylogenetic studies have greatly impacted upon the circumscription of taxa within the rosid clade, resulting in novel relationships at all systematic levels. In many cases the floral structure of these taxa has never been compared, and in some families,

Mechanical damping of wood as related to species classification: a preliminary survey [PDF]

open access: yes, 2009
International audienceSome morphological and biochemical taxonomic markers are also affecting factors of dynamic mechanical properties of wood. Thus, could these properties reflect the classification/phylogeny of taxa?
