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.

Dispersion-relation-preserving finite difference schemes for computational acoustics

, 1993
Acoustics problems are governed by the linearized Euler equations. According to wave propagation theory, the number of wave modes and their wave propagation characteristics are all encoded in the dispersion relations of the governing equations.

Visible continuum generation in air–silica microstructure optical fibers with anomalous dispersion at 800 nm

, 2000
We demonstrate experimentally for what is to our knowledge the first time that air–silica microstructure optical fibers can exhibit anomalous dispersion at visible wavelengths.

London dispersion in molecular chemistry--reconsidering steric effects.

Angewandte Chemie, 2015
London dispersion, which constitutes the attractive part of the famous van der Waals potential, has long been underappreciated in molecular chemistry as an important element of structural stability, and thus affects chemical reactivity and catalysis ...

Transmission of stationary nonlinear optical pulses in dispersive dielectric fibers. I. Anomalous dispersion

, 1973
Theoretical calculations supported by numerical simulations show that utilization of the nonlinear dependence of the index of refraction on intensity makes possible the transmission of picosecond optical pulses without distortion in dielectric fiber ...

On the dispersion models and atmospheric dispersion

International Journal of Global Warming, 2011
As an air pollutant is transported, the pollutant disperses into the surrounding air so that it arrives at a lower concentration than it was on leaving the source. Strict environmental regulations worldwide resulted in a growing concern about the validity of air quality dispersion models.

Dispersion in Sound

Angelaki, 2018
The premise of this brief study is an examination of the conditions in which a decentering can occur in the Blanchotian manner of the experience of listening to music.

Dispersion, agglomération et re-dispersion ?

Revue d’Économie Régionale & Urbaine, 2002
Résumé Cet article a pour but de présenter de manière synthétique les principaux résultats théoriques obtenus récemment en économie géographique. Pour cela, on utilise un nouveau modèle qui permet d’établir de manière simple des résultats analytiques. Ce modèle est ensuite utilisé pour étudier un certain nombre de questions peu abordées jusqu’à présent
