This is the exponential (or Malthus's “geometric”) model—the simplest possible model of population growth. It assumes a constant growth rate r that can be positive, zero, or negative (although not smaller than −1). The continuous equivalent to Eq. (18) is the differential equation: ...
We can define derivatives for stochastic growth rate, using exact formula derived in Tuljapurkar (1990b). First use Eqs. (19) and (22) to obtain stationary sequences of population structures Ut and reproductive value vectors Vt. Now the growth rate a = a(Bt) is a function of the sequenc...
from Chapter 19 / Lesson 5 89K Explore population growth rates and how to determine the per capita growth rate of a populate using a simple formula. Discover why studying per capita growth rates is important and practice using the formula with sample populations. Related to this Questi...
First, the MOF-derived hollow NiS2 spheres as the nanoreactor can effectively restrain the agglomeration of SnS2 by providing sufficient reaction sites for the growth and firm anchoring of SnS2 nanosheets. Second, the N-doped carbon skeleton in-situ-formed from the carbonization of MOFs can not...
In this work, we demonstrate the role of the loading rate in mechanosensing. First, we stretch cells at different frequencies and amplitudes, and show that their mechanosensing response (as measured by YAP nuclear localization and focal adhesion growth) can be explained by the applied loading rate...
Guo et al. BMC Genomics (2015) 16:177 Page 2 of 15 skeletal muscle also contains a considerable population of fibroblasts, intramuscular adipocytes, and other cell types including nerve cells and blood vessels [3]. All of these components contribute to skeletal muscle growth, most likely in a...
We calculated the variance inflation factor (VIF) value of AOga against CAGexp to assess the collinearity effect according to the formula of VIF and the AOga variance explained by CAGexp (49% by our study [18] and about 50% in the previous studies [32]). Generally, a VIF value exceeding...
[1821]: chapter 6). The restrictive conditions Ricardo utilizes to arrive at this fundamental result involve, in particular, a labor theory of exchange value: It is supposed that the relative prices of commodities are explained by the quantities of labor time directly and indirectly required in ...
At week 25 of each year, we record the per capita growth rate over the previous year as well as the per capita growth rate from the initial population size (see Scott et al. (2014) for associated formulas). We also record the total fox population and the number of eagles feeding on ...
