Marsupial relationships and a timeline for marsupial radiation in South Gondwana.
Recent marsupials include about 280 species divided into 18 families and seven orders. Approximately 200 species live in Australia/New Guinea. The remaining species inhabit South America with some of these secondarily ranging into North America. In this study, we examine marsupial relationships and estimate their divergences times using complete mitochondrial (mt) genomes. The sampling, which i...
متن کاملSupporting Inter-Group Relationships in Human-Centered Chance Discovery
Human-centered chance discovery involves ad-hoc teams of experts who inspect the output of a chance discovery algorithm and develop scenarios for decision making. The team members typically are from different areas, such as product design or marketing, and have relationships to their own teams in these areas. Therefore the inter-team relationships affect the performance of the chance discovery ...
متن کاملChance factors in studies of quantitative structure-activity relationships.
Multiple regression analysis is a basic statistical tool used for QSAR studies in drug design. However, there is a risk or arriving at fortuitous correlations when too many variables are screened relative to the number of available observations. In this regard, a critical distinction must be made between the number of variables screened for possible correlation and the number which actually app...
متن کاملGive chance a chance
How did I get to become a cell biologist? Or, more generally, why do things happen the way they do? The answer provided by the philosopher Democritus and later adopted by Jacques Monod is "everything existing in the universe is the fruit of chance and necessity." While I read Monod's book Chance and Necessity as an undergraduate student, little did I appreciate the accuracy of this citation and...
متن کاملInduction of a marsupial density model using genetic programming and spatial relationships
Machine learning techniques have been developed that allow the induction of spatial models for the prediction of habitat types and population distribution. However, most learning approaches are based on a propositional language for the development of models and therefore cannot express a wide range of possible spatial relationships that exist in the data. This paper compares the application of ...
