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 ...

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 ...

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 ...

Bluetongue Disease Control in Northern Ireland During 2017 and 2018
Frontiers in Veterinary Science, 2019 Since the emergence of bluetongue virus in central and northern Europe in 2006, Northern Ireland's (NI) surveillance programme has evolved to include the use of risk assessments and simulation models to monitor the risk of bluetongue incursion. Livestock

Frequency-Oriented Subsampling by Photonic Fourier Transform and I/Q Demodulation
IEEE Photonics Journal, 2017 Subsampling can directly acquire a passband within a broad radio frequency (RF) range, avoiding down-conversion and low-phase-noise tunable local oscillation. However, subsampling suffers from band folding and self-image interference.
