Development of forest structure and leaf area in secondary forests regenerating on abandoned pastures in Central Amazonia [PDF]
, 2005 The area of secondary forest (SF) regenerating from pastures is increasing in the Amazon basin; however, the return of forest and canopy structure following abandonment is not well understood. This study examined the development of leaf area index (LAI),

Generating Compact Tree Ensembles via Annealing
, 2020 Tree ensembles are flexible predictive models that can capture relevant variables and to some extent their interactions in a compact and interpretable manner. Most algorithms for obtaining tree ensembles are based on versions of boosting or Random Forest.

Fragmentation of Random Trees [PDF]
, 2014 We study fragmentation of a random recursive tree into a forest by repeated removal of nodes. The initial tree consists of N nodes and it is generated by sequential addition of nodes with each new node attaching to a randomly-selected existing node.

Trees, Forests, and Total Positivity: I. $q$-Trees and $q$-Forests Matrices [PDF]
The Electronic Journal of Combinatorics, 2021 We consider matrices with entries that are polynomials in $q$ arising from natural $q$-generalisations of two well-known formulas that count: forests on $n$ vertices with $k$ components; and rooted labelled trees on $n+1$ vertices where $k$ children of the root are lower-numbered than the root.

Trajectories of Physical Function in Canadian Children with Juvenile Idiopathic Arthritis
Arthritis Care &Research, Accepted Article.Objectives We describe trajectories of physical function in children newly diagnosed with juvenile idiopathic arthritis (JIA) and identify trajectories with persisting functional impairments and associated baseline characteristics. Methods We included patients enrolled in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry ...

Abiotic controls on macroscale variations of humid tropical forest height [PDF]
, 2016 Spatial variation of tropical forest tree height is a key indicator of ecological processes associated with forest growth and carbon dynamics. Here we examine the macroscale variations of tree height of humid tropical forests across three continents and ...
