Archaeobotany: The wheat and the chaff

Enhanced: Separating the Wheat from the Chaff

Seeing the world around you is like drinking from a firehose. The flood of information that enters the eyes could easily overwhelm the capacity of the visual system. To solve this problem, a mechanism-attention-allows selective processing of the information relevant to current goals. As the eminent physiological psychologist Helmholtz [HN2], [HN3], [HN4] noted over a hundred years ago, even wit...

Winnowing Wheat from Chaff: The Chunking GA

In this work, we investigate the ability of a Chunking GA (ChGA) to reduce the size of variable length chromosomes and control bloat. The ChGA consists of a standard genetic algorithm augmented by a communal building block memory system and associated memory chromosomes and operators. A new mxn MaxSum fitness function used for this work is also described. Results show that a ChGA equipped with ...

Polymorphisms and atrial fibrillation: sorting the wheat from the chaff.

In the last 5 years, we have gained an increasing appreciation for the genetic contribution to atrial fibrillation (AF). While Mendelian families with AF have been reported, they have typically been considered rare. Studies from Framingham and Iceland have demonstrated a genetic basis for AF in the general population. Family members of those with AF have an odds ratios of 1.8 for developing the...
