E.: Automatic clustering of orthologs and inparalogs from pairwise species comparisons.
- Journal of Molecular Biology
, 2001
"... Orthologs are genes in different species that originate from a single gene in the last common ancestor of these species. Such genes have often retained identical biological roles in the present-day organisms. It is hence important to identify orthologs for transferring functional information betwee ..."

protein families. Paralogs that predate the species split, which we call out-paralogs, can easily be confused with true orthologs. Paralogs that arose after the species split, which we call in-paralogs, however, are bona ®de orthologs by de®nition. Orthologs and in-paralogs are typically detected
Empathy: Its ultimate and proximate bases
- Behavioral and Brain Sciences
, 2002
"... The empathy literature is characterized by debate regarding the nature of the phenomenon. We propose a unified theory of empathy, divided into ultimate and proximate levels, grounded in the emotional link between individuals. On an ultimate level, emotional linkage supports group alarm, vicariousnes ..."

, vicariousness of emotions, mother-infant responsiveness, and the modeling of competitors and predators; these exist across species and greatly effect reproductive success. Proximately, emotional linkage arises from a direct mapping of another's behavioral state onto a subject's behavioral
Incremental Evolution of Complex General Behavior
- Adaptive Behavior
, 1997
"... Several researchers have demonstrated how complex action sequences can be learned through neuro-evolution (i.e. evolving neural networks with genetic algorithms). However, complex general behavior such as evading predators or avoiding obstacles, which is not tied to specific environments, turns out ..."

Greed and Grievance in Civil Wars
- Oxford Economic Papers
, 2004
"... Abstract: Of the 27 major armed conflicts that occurred in 1999, all but two took place within national boundaries. As an impediment to development, internal rebellion especially hurts the world's poorest countries. What motivates civil wars? Greed or grievance? This paper compares two contrast ..."

countries return to conflict repeatedly. Are they conflict-prone or is there a feedback effect whereby conflict generates grievance which in turn generates further conflict? It is shown why such a feedback effect might be present in both greed-motivated and grievance rebellions. The results contrast
Psychological stress and the human immune system: A meta-analytic study of 30 years of inquiry
- Psychological Bulletin
, 2004
"... The present report meta-analyzes more than 300 empirical articles describing a relationship between psychological stress and parameters of the immune system in human participants. Acute stressors (lasting minutes) were associated with potentially adaptive upregulation of some parameters of natural i ..."

Chronic stressors were associated with suppression of both cellular and humoral measures. Effects of event sequences
Multiple trophic levels of a forest stream linked to terrestrial litter inputs
- Science
, 1997
"... The importance of terrestrial-aquatic linkages was evaluated by a large-scale, 3-year exclusion of terrestrial leaf litter inputs to a forest stream. Exclusion of leaf litter had a strong bottom-up effect that was propagated through detritivores to predators. Most invertebrate taxa in the predominan ..."

Effects of spatial grouping on the functional response of predators
- Pop. Biol
, 1999
"... A unified mechanistic approach is given for the derivation of various forms of functional response in predator prey models.. The derivation is based on the principle of mass action but with the crucial refinement that the nature of the spatial distribution of predators and or opportunities for preda ..."

The design and implementation of a sequence database system
- In VLDB
, 1996
"... This paper discusses the design and implementation of SEQ, a database system with support for sequence data. SEQ models a sequence as an ordered collection of records, and supports a declarative sequence query language based on an algebra of query operators, thereby permitting algebraic query optimi ..."
