Influenced by traditional thought, accompany with social stability, the development of production, medical improvement, inadequate experience and the blindness imitated the Russian mode, China had presented the tendency of high born, low death and high growth.
Complexity of Homogeneous Spaces and Growth of Multiplicities
We give a representation-theoretic interpretation of this number as the exponent of growth for multiplicities of simple G-modules in the spaces of sections of homogeneous line bundles on G/H.
A necessary and sufficient geometric condition on the growth of the boundary of approximate tiles is reduced to a problem in Fourier analysis that is shown to have an elegant simple solution in dimension one.
We prove a Tauberian theorem of the form $\phi * g (x)\sim p(x)w(x)$ as $x \to \infty,$ where p(x) is a bounded periodic function and w(x) is a weighted function of power growth.
A complex Radon measure μ on ?n is said to be of at most exponential-quadratic growth if there exist positive constants C and α such that.
In this paper, a C-K model with solvable endogenous fertility under the strongly additive utility function is presented.
By numerical analysis, the fertility decreases with the per capita capital and per capita consumption increasing and increases with the per capita capital and per capita consumption decreasing on the economic growth path are obtained.
However, recent studies have documented that the practice of this system has led to dramatic decreases in soil fertility and forest environment as well as in productivity.
Organic C, total N, available N and available K content increased gradually, and soil fertility was enhanced.
As no male sterile genes have been reported in this region, ms157 could be a novel gene related to fertility.
For one-dimensional diffusion processes and birth-death processes, these bounds are sharp in the sense that the upper one and the lower one are only different by a constant.
Based on the fundamental processes of birth, death, dispersal and speciation, the neutral theory provided the first mechanistic explanation of species abundance distribution commonly observed in natural communities.

Some diagnostics in nonlinear reproductive dispersion models
This article discusses the problem of the detection of influential cases in nonlinear reproductive dispersion models (NRDM).
If the basic reproductive number σ is below unity, O is globally stable and the disease always dies out.
This was done by determining the duration of each life stage of the mites, the intrinsic rate of population increase (rm), mean generation time (T) and net reproductive rate (R0) of the spider mites on each of the host plant species.
