Data Mining and KDD: A Shifting Mosaic

Data Mining is an idea based on a simple analogy. The growth of data warehousing has created mountains of data. The mountains represent a valuable resource to the enterprise. But to extract value from these data mountains, we must "mine" for high-grade "nuggets" of precious metal -the gold in data warehouses and data marts. The analogy to mining has proven seductive for business. Everywhere the...

An indicator of forest dynamics using a shifting landscape mosaic

The composition of a landscape is a fundamental indicator in land-cover pattern assessments. The objective of this paper was to evaluate a landscape composition indicator called ‘landscape mosaic’ as a framework for interpreting land-cover dynamics over a 9-year period in a 360,000 km study area in the southern United States. The indicator classified a land parcel into one of 19 possible landsc...

Large Variations in HIV-1 Viral Load Explained by Shifting-Mosaic Metapopulation Dynamics

The viral population of HIV-1, like many pathogens that cause systemic infection, is structured and differentiated within the body. The dynamics of cellular immune trafficking through the blood and within compartments of the body has also received wide attention. Despite these advances, mathematical models, which are widely used to interpret and predict viral and immune dynamics in infection, t...

Shifting Sugars and Shifting Paradigms

No organism lives in a constant environment. Based on classical studies in molecular biology, many have viewed microbes as following strict rules for shifting their metabolic activities when prevailing conditions change. For example, students learn that the bacterium Escherichia coli makes proteins for digesting lactose only when lactose is available and glucose, a better sugar, is not. However...
