The Gompertz curve or Gompertz function is a type of mathematical model for a time series, named after Benjamin Gompertz (1779–1865). It is a sigmoid function which describes growth as being slowest at the start and end of a given time period. The right-side or future value asymptote of the function is approached much more gradually by the ...
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. When the relative growth rate (not the absolute growth rate) is constant ...
The doubling time (t d) of a population is the time required for the population to grow to twice its size. [24] We can calculate the doubling time of a geometric population using the equation: N t = λ t N 0 by exploiting our knowledge of the fact that the population (N) is twice its size (2N) after the doubling time.

Agrobacterium tumefaciens[ 3][ 2] is the causal agent of crown gall disease (the formation of tumours) in over 140 species of eudicots. It is a rod-shaped, Gram-negative soil bacterium. [ 4] Symptoms are caused by the insertion of a small segment of DNA (known as T-DNA, for 'transfer DNA', not to be confused with tRNA that transfers amino acids ...
Two-thirds of U.S. adults say they’re pessimistic about the state of politics in America, according to a new AP-NORC poll. The survey shows 66 percent of U.S. adults say they’re either very ...
Saccharomyces cerevisiae ( / ˌsɛrəˈvɪsi.iː /) ( brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
Sen. Laphonza Butler (D-Calif.) said she has “no concern” about Vice President Harris’s reversals on policy issues, saying the Democratic nominee is “a human being.” In an interview on ...
The average doubling time is 19 to 50 hours. 1 mM sodium pyruvate, penicillin (100 units/ml) and streptomycin (100 μg/ml) are also commonly added to inhibit bacterial contamination. Cultures should be maintained at cell densities in the range 2-9x10 5 cells/ml at 37 °C, 5% CO 2. Cells are non-adherent. [5]
