One may then define the generation time as the time it takes for the population to increase by a factor of . For example, in microbiology , a population of cells undergoing exponential growth by mitosis replaces each cell by two daughter cells, so that R 0 = 2 {\displaystyle \textstyle R_{0}=2} and T {\displaystyle T} is the population doubling ...
The doubling time is the time it takes for a population to double in size/value. It is applied to population growth , inflation , resource extraction , consumption of goods, compound interest , the volume of malignant tumours , and many other things that tend to grow over time.
The effective population size (N e) is the size of an idealised population that would experience the same rate of genetic drift as the real population. The effective population size is normally smaller than the census population size N, partly because chance events prevent some individuals from breeding, and partly due to background selection and genetic hitchhiking.
"My generation is going to have a harder time than boomers. Boomers, they had pensions," Don tells Fortune . But "all you can do when you get knocked off your feet is get back up and dust off."
The rate of evolution is quantified as the speed of genetic or morphological change in a lineage over a period of time. The speed at which a molecular entity (such as a protein, gene, etc.) evolves is of considerable interest in evolutionary biology since determining the evolutionary rate is the first step in characterizing its evolution.

Likewise, page 32 of the 1988 Star Trek: The Next Generation Writer's/Director's Guide for season two states: …the digit following the decimal point counts one-tenth of a day. This was demonstrated by the ship's chronometer in the TOS-Remastered episode, "The Naked Time," and by Captain Varley's video logs in the TNG episode "Contagion". The ...
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. [1] The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period.
This isn’t the first time that better sleep has been linked with a lower risk of dementia: A study published in October even found that people with sleep apnea are more likely to develop dementia.
