Expanding an abridged life table

Heartwater: an abridged historical account.

Heartwater was first recognised and recorded in South Africa as early as 1838. Since then the disease has been described from almost all the countries in Africa south of the Sahara, from certain islands around Africa and from a number of islands in the Caribbean. Most of the research on the disease, at least until fairly recently, was conducted in South Africa. Progress in research on the disea...

All I Know: An Abridged Report1

Current approaches to formalizing non-monotonic reasoning using logics of belief require new metalogical properties over sets of sentences to be defined. This research attempts to show how some of these patterns of reasoning can be captured using only the classical notions of logic (satisfiability, validity, implication). This is done by extending a logic of belief so that it is possible to say...

Comparison of two methods of constructing abridged life tables.

Life at the front of an expanding population.

Environmental changes have caused episodes of habitat expansions in the evolutionary history of many species. These range changes affect the dynamics of biological evolution in multiple ways. Recent microbial experiments as well as simulations suggest that enhanced genetic drift at the frontier of a two-dimensional range expansion can cause genetic sectoring patterns with fractal domain boundar...

But below the ocean surface is a different story. We know more about the facade of Mars than about the 75 percent of our own plan...
