An overview of the HYSPLIT_4 modelling system for trajectories, dispersion and deposition
Australian meteorological magazine, 1998 The HYSPLIT_4 (Hybrid Single-Particle Lagrangian Integrated Trajectory) model is designed for quick response to atmospheric emergencies, diagnostic case studies, or climatological analyses using previously gridded meteorological data. Calculations may be

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 ...

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.

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.

A generally applicable atomic-charge dependent London dispersion correction.
Journal of Chemical Physics, 2018 The so-called D4 model is presented for the accurate computation of London dispersion interactions in density functional theory approximations (DFT-D4) and generally for atomistic modeling methods.
