The midgut is a uniquely tractable model to study adaptive growth; not only can gene expression be manipulated and lineages traced at single-cell and whole-tissue levels, but complete population counts of all cell types are possible.
Even as it seeks to complete the official population count for 2000, the Census Bureau finds itself engaged in a battle with House Republicans over how the bureau is conducting its head count.
This assumption is clearly an approximation but more complete animal-population counts of comparable length do not seem to exist.
Estimation in population count models is, therefore, completed through likelihood-based approaches, requiring approximation of the integral over the random effects.
Since only a small percentage of cases and controls did not complete a study interview, population counts were derived from the interviewed sample without adjustment for interview completion.

The parametric statistics returned for each supplied polygon include the count (number of grid cells used in the analysis), minimum population count, maximum population count, range of population counts, mean population counts, and standard deviation of population counts.
A higher percentage of households completed and returned census forms this year than in 1990, reversing a three-decade trend away from participation in the national population count, census officials said today.
