Comparative analysis of hepatitis C virus phylogenies from coding and non-coding regions: the 5' untranslated region (UTR) fails to classify subtypes (2006)

Hraber, Peter T, Fischer, William, Bruno, William J, Leitner, Thomas, Kuiken, Carla

Abstract Background The duration of treatment for HCV infection is partly indicated by the genotype of the virus. For studies of disease transmission, vaccine design, and surveillance for novel...

HLA and HIV Infection Progression: Application of the Minimum Description Length Principle to Statistical Genetics (2005)

Hraber, Peter T., Korber, Bette T., Wolinsky, Steven, Erlich, Henry A., Trachtenberg, Elizabeth A., Kepler, Thomas B.

The minimum description length (MDL) principle states that the best model to account for some data minimizes the sum of the lengths, in bits, of the descriptions of the model and the residual error....

On the species of origin: diagnosing the source of symbiotic transcripts (2001)

Hraber, Peter T, Weller, Jennifer W

Abstract Background Most organisms have developed ways to recognize and interact with other species. Symbiotic interactions range from pathogenic to mutualistic. Some molecular mechanisms of...

Dynamics, Computation, and the "Edge of Chaos": A Re-Examination (2000)

Melanie Mitchell, James P. Crutchfield, Peter T. Hraber

In this paper we review previous work and present new work concerning the relationship between dynamical systems theory and computation. In particular, we review work by Langton [21] and Packard [29]...

The Ecology of Echo (1999)

Peter T. Hraber, Terry Jones, Stephanie Forrest

This paper describes one such model, called Echo, whose emphasis is on the essential components and interactions of ecosystems. Many CAS can be viewed as ecologies (e.g., [24, 46]), but our focus in...

Evidence for Adaptive Evolutionary Convergence in the Base Composition . . . (1997)

Schultes Hraber Labean, Erik Schultes, Peter T. Hraber, Thomas H. Labean

Like proteins, single-stranded RNA's (ssRNAs) undergo intramolecular folding into complex conformations which determine their metabolic function1-3. We have compiled nucleotide composition data,...

Community Assembly in a Model Ecosystem (1996)

Peter T. Hraber, Bruce T. Milne

Environmental and biotic factors regulate species abundance and the composition of ecological communities. However, it is difficult to demonstrate principles of community assembly in nature due to...

Revisiting the Edge of Chaos: Evolving Cellular Automata to Perform Computations (1994)

Melanie Mitchell, Peter T. Hraber, James P. Crutchfield

We present results from an experiment similar to one performed by Packard [24], in which a genetic algorithm is used to evolve cellular automata (CA) to perform a particular computational task....

Comparative Analysis of Expressed Sequences in Phytophthora sojae1

Qutob, Dinah, Hraber, Peter T., Sobral, Bruno W.S., Gijzen, Mark

Phytophthora sojae (Kaufmann and Gerdemann) is an oomycete that causes stem and root rot on soybean (Glycine max L. Merr) plants. We have constructed three cDNA libraries using mRNA isolated from...

Global Similarities in Nucleotide Base Composition Among Disparate Functional Classes of Single-Stranded RNA

Erik Schultes, Peter T. Hraber, Thomas H. LaBean

The number of distinct functional classes of single-stranded RNAs (ssRNAs) and the number of sequences representing them are substantial and continue to increase. Organizing this data in an...
