A new, fast, and efficient image codec based on set partitioning in hierarchical trees

IEEE Trans. Circuits Syst. Video Technol., 1996
Embedded zerotree wavelet (EZW) coding, introduced by Shapiro (see IEEE Trans. Signal Processing, vol.41, no.12, p.3445, 1993), is a very effective and computationally simple technique for image compression.

Tree by Tree

2023
This book is a warning and a toolkit for the future of forest recovery. The book investigates the critical biological threats endangering tree species native to the forests of eastern North America, providing a needed focus on this plight. The book suggests that if we are to save our forests, the first step is to recognize the threats in front of us ...

To tree or not to tree

Molecular Ecology, 1998
The practice of tracking geographical divergence along a phylogenetic tree has added an evolutionary perspective to biogeographic analysis within single species. In spite of the popularity of phylogeography, there is an emerging problem. Recurrent mutation and recombination both create homoplasy, multiple evolutionary occurrences of the same character ...

Genome trees and the tree of life

Trends in Genetics, 2002
Genome comparisons indicate that horizontal gene transfer and differential gene loss are major evolutionary phenomena that, at least in prokaryotes, involve a large fraction, if not the majority, of genes. The extent of these events casts doubt on the feasibility of constructing a 'Tree of Life', because the trees for different genes often tell ...

Algorithms on Strings, Trees, and Sequences - Computer Science and Computational Biology

, 1997
Linear-Time Construction of Suffix Trees We will present two methods for constructing suffix trees in detail, Ukkonen’s method and Weiner’s method. Weiner was the first to show that suffix trees can be built in linear time, and his method is presented ...

On Trees and Logs [PDF]

open access: possibleSSRN Electronic Journal, 2002
Abstract In this paper we contrast the main workhorse model in asset pricing theory, the Lucas (1978) tree model (LT-Model), to a benchmark model in financial equilibrium theory, the real assets model (RA-Model). It is commonly believed that the two models entail similar conclusions since the LT-Model is a special case of the RA-Model.

A Tree That's Not a Tree

Mathematics Magazine, 2006
ture game Trinity, you have a gnomon you must screw into a hole?but the threads in the hole are going the wrong way. Wandering about, you encounter an "abstract sculpture," inscribed with the words Felix Klein 1849-1925. Nearby are strange leafy tunnels.
