Decentralisation, Dispersal and Dispersion

South African Geographical Journal, 1974
Abstract The terms decentralisation, dispersal and dispersion are used extensively in the literature of regional economic development. The first may refer to the decentralisation of core areas, to the process of dispersal, or to the state of a spatial system. The second term is concerned mainly with process and the third with pattern but no consistency

Dispersal in microbes: fungi in indoor air are dominated by outdoor air and show dispersal limitation at short distances

ISME Journal, 2013
The indoor microbiome is a complex system that is thought to depend on dispersal from the outdoor biome and the occupants’ microbiome combined with selective pressures imposed by the occupants’ behaviors and the building itself.

Dispersion-managed solitons at normal average dispersion

Nonlinear Optics '98. Materials, Fundamentals and Applications Topical Meeting (Cat. No.98CH36244), 1998
We find that in a dispersion-managed fiber, in which the strength of the dispersion management is above some threshold, solitons can exist with normal average dispersion. When the normal average dispersion is below some limiting value there exist two soliton solutions with the same pulse duration and different pulse energies.

New dispersion-decreasing dispersion management

SPIE Proceedings, 2004
In this paper, we introduce a new dispersion management method of realizing exponentially decreasing dispersion fiber by using only two kinds of segments of fibers with different dispersions connected together. Exponentially decreasing dispersion fiber is used to obtain the optimum soliton transmission situation.

Dispersion-managed breathers with average normal dispersion

Optics Letters, 1998
Analytic and numerical evidence is presented that demonstrates that a dispersion-managed breather can be supported in an optical fiber even when the average dispersion is in the normal regime. This nonlinear behavior, which is contrary to guiding-center theory, is shown to originate from the reversible dynamics associated with the strong quadratic ...

Dispersion-managed solitons with net positive dispersion

Optics Letters, 1998
Propagation of dispersion-managed solitons in the net positive-dispersion regime is studied. A new form of sideband generation that is due to perturbations is identified. Some collision anomalies are pointed out.

Competition for Dispersal in Ant-Dispersed Plants

Science, 1981
Two closely related and coexisting plants (Chenopodiaceae) of the Australian arid zone are adapted for seed dispersal by ants. These facultatively perennial shrubs persist in saltbush communities largely as a result of highly directional dispersal to ant mounds, where conditions are favorable for establishment and growth.

Good Dispersion, Bad Dispersion

Review of Economic Studies
Abstract We document that most dispersion in marginal revenue products of inputs occurs across plants within firms rather than between firms. This is commonly thought to reflect misallocation: dispersion is “bad”. However, we show that eliminating frictions hampering internal capital markets in a multi-plant firm model may in fact ...

Intercontinental Dispersal III

1952
So monotonous is the behavior of plants in dispersal that its students can hardly avoid in the end a feeling of boredom. The same features constantly recur upon the map; the same tracks repeat themselves without end. Soon a point is reached, where the budding phytogeographer unconsciously begins to inquire, why there is seemingly no end to the same ...
