Dispersion measures and dispersive orderings [PDF]
Statistics & Probability Letters, 2003 In this paper, the comparison of random variables according to the functionals of a general class of dispersion measures is characterized in terms of the dilation order. The Gini's mean difference is a particular member of this general class. In addition, a new and weaker order, called the second-order absolute Lorenz ordering, is introduced, and we ...

Dispersive stabilization [PDF]
Bulletin of the London Mathematical Society, 2010 Ill posed linear and nonlinear initial value problems may be stabilized, that it converted to to well posed initial value problems, by the addition of purely nonscalar linear dispersive terms. This is a stability analog of the Turing instability. This idea applies to systems of quasilinear Schrödinger equations from nonlinear optics.

Shock Waves in Dispersive Hydrodynamics with Nonconvex Dispersion [PDF]
SIAM Journal on Applied Mathematics, 2017 Dissipationless hydrodynamics regularized by dispersion describe a number of physical media including water waves, nonlinear optics, and Bose-Einstein condensates. As in the classical theory of hyperbolic equations where a non-convex flux leads to non-classical solution structures, a non-convex linear dispersion relation provides an intriguing ...

Secondary wind dispersal enhances long-distance dispersal of an invasive species in urban road corridors [PDF]
, 2011 Roads contribute to habitat fragmentation and function as dispersal barriers for many organisms. At the same time many nonnative plant species are associated with road systems, a relationship that has been explained by the availability of disturbed ...

SSRN Electronic Journal, 2017 Estimation error has plagued quantitative finance since Harry Markowitz launched modern portfolio theory in 1952. Using random matrix theory, we characterize a source of bias in the sample eigenvectors of financial covariance matrices. Unchecked, the bias distorts weights of minimum variance portfolios and leads to risk forecasts that are severely ...

Ants cannot account for interpopulation dispersal of the arillate pea Daviesia triflora [PDF]
, 2009 • Estimating distances and rates of seed dispersal, especially long-distance dispersal (LDD), is critical for understanding the dynamics of patchily distributed populations and species’ range shifts in response to environmental change.
