Hamiltonian dynamics of breathers with third-order dispersion [PDF]
, 2001 We present a nonperturbative analysis of certain dynamical aspects of breathers (dispersion-managed solitons) including the effects of third-order dispersion.

NOAA’s HYSPLIT Atmospheric Transport and Dispersion Modeling System
, 2015 The Hybrid Single-Particle Lagrangian Integrated Trajectory model (HYSPLIT), developed by NOAA’s Air Resources Laboratory, is one of the most widely used models for atmospheric trajectory and dispersion calculations.

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

IEEE Access, 2020 A novel structure is studied with implanting sporadic slots inside a photonic crystal waveguide (PCW) to form sporadic-slot PCW (SSPCW) for realizing compact, all-optical buffers with lowdispersion, distortion, and attenuation (DDA).

Achromatic Metalens over 60 nm Bandwidth in the Visible and Metalens with Reverse Chromatic Dispersion. [PDF]
Nano letters (Print), 2017 In this Letter, we experimentally report an achromatic metalens (AML) operating over a continuous bandwidth in the visible. This is accomplished via dispersion engineering of dielectric phase shifters: titanium dioxide nanopillars tiled on a dielectric ...

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 Schr dinger equations from nonlinear optics.

Exponential decay of dispersion managed solitons for vanishing average dispersion [PDF]
, 2010 We show that any $L^2$ solution of the Gabitov-Turitsyn equation describing dispersion managed solitons decay exponentially in space and frequency domains. This confirms in the affirmative Lushnikov's conjecture of exponential decay of dispersion managed

Interspersions and Dispersions [PDF]
Proceedings of the American Mathematical Society, 1993 An array A = ( a i j ) A = ({a_{ij}}) of all the positive integers is an interspersion if the terms of any two rows, from some point on, alternate in size, and a dispersion if, for a suitable sequence (

The Hydrodynamic Dispersion Characteristics of Coral Sands
Journal of Marine Science and Engineering, 2019 Dispersion characteristics are important factors affecting groundwater solute transport in porous media. In marine environments, solute dispersion leads to the formation of freshwater aquifers under islands.
