An aggregated distribution, commonly found among predators, parasites, and plants is a highly uneven statistical distribution pattern in which they collect or aggregate in regions. These regions may be widely separated, particularly within animal distributions that are influenced by prey or host densities.
When b = 1 and a > 1, there is over-dispersion (small-scale aggregation). When b is > 1, the degree of aggregation varies with p. Turechek et al [62] have showed that the binary power law describes numerous data sets in plant pathology. In general, b is greater than 1 and less than 2. The fit of this law has been tested by simulations. [63]
In molecular biology, protein aggregation is a phenomenon in which intrinsically-disordered or mis-folded proteins aggregate (i.e., accumulate and clump together) either intra- or extracellularly. [1] [2] Protein aggregates have been implicated in a wide variety of diseases known as amyloidoses, including ALS, Alzheimer's, Parkinson's and prion ...
Allee effects are classified by the nature of density dependence at low densities. If the population shrinks for low densities, there is a strong Allee effect. If the proliferation rate is positive and increasing then there is a weak Allee effect. The null hypothesis is that proliferation rates are positive but decreasing at low densities.
Erythrocyte aggregation is the main determinant of blood viscosity at low shear rate. Rouleaux formation also determines Erythrocyte sedimentation rate which is a non-specific indicator of the presence of disease. [6] Influence of erythrocyte aggregation on in vivo blood flow is still a controversial issue. [7]
Research funding is a term generally covering any funding for scientific research, in the areas of natural science, technology, and social science.Different methods can be used to disburse funding, but the term often connotes funding obtained through a competitive process, in which potential research projects are evaluated and only the most promising receive funding.
In economics, the field of public finance deals with three broad areas: macroeconomic stabilization, the distribution of income and wealth, and the allocation of resources. . Much of the study of the allocation of resources is devoted to finding the conditions under which particular mechanisms of resource allocation lead to Pareto efficient outcomes, in which no party's situation can be ...
A Moran process or Moran model is a simple stochastic process used in biology to describe finite populations. The process is named after Patrick Moran , who first proposed the model in 1958. [ 1 ] It can be used to model variety-increasing processes such as mutation as well as variety-reducing effects such as genetic drift and natural selection .
