2 That is, deforestation is essentially referring to a change in land use, not in tree cover. Defining deforestation thus implies a definition of forest, which, in the FRA, combines physical criteria (minimum thresholds of 10 percent canopy cover, 0.5 [1.2 acres] ha in area and 5 m [...
We can define derivatives for stochastic growth rate, using exact formula derived inTuljapurkar (1990b). First use Eqs. (19) and (22) to obtain stationary sequences of population structuresUtand reproductive value vectorsVt. Now the growth ratea=a(Bt) is a function of the sequence of rando...
This statistic shows the percentage of the population in Manitoba in low income from 2000 to 2021 according to low income measures (LIMs). 13.9 percent of the population of Manitoba was considered to be in low income in 2021. Percentage of Manitoba's population in low income from 2000 to ...
the values can be listed as a finite or infinite sequence of values 1, 2, 3 …. For a discrete random variable, its probability distribution is any graph, table or formula that assigns a probability to each possible value. The sum of all probabilities must be 1, a...
We took BTHUA as an example to verify the results of the derivation of the population gravity center in 3.2 simulated urban agglomerations. We calculated the latitude and longitude of the BTHUA population center of gravity from 2005 to 2018 according to the population gravity center formula in ...
the quality score is obtained from the Q score of the original VCF file, which ranges from 0 to 1. For ExpansionHunter, we defined a quality score based on the copy numbers and confidence intervals of each allele in the called genotype. Each allele’s score is calculated by the formula: ...

7d). The average Pearson correlation coefficient between the change in median fixation duration and fraction of SR cells equaled 0.26 (averaged across bootstrap samples from n = 10–29 fish, see “Methods”) and was significantly larger than randomly shuffled controls (p < 0.001, one...
A Z-score was calculated to account for variation in ages within each study visit using the following formula: (Microbiota age of child—median microbiota age of ‘healthy’ child at same study visit)/standard deviation of microbiota age of ‘healthy’ child at same study visit. Reporting ...
The formula for calculating stratified random sampling sample size, n = z2*S2*deff/d2, was used to calculate the sample size required for analysis. We defined the two-sided significance levels α = 0.05, 1 − β = 0.8, and zα/2 = 1.96. The deff value of ...
