Lenses and Learners

no code implementations5 Mar 2019 Brendan Fong, Michael Johnson

Lenses are a well-established structure for modelling bidirectional transformations, such as the interactions between a database and a view of it.

A Model for Anisotropic Interstellar Scattering and its Application to Sgr A*

1 code implementation3 May 2018 Dimitrios Psaltis, Michael Johnson, Ramesh Narayan, Lia Medeiros, Lindy Blackburn, Geoff Bower

For expected values of the inner scale, the scattering kernel for all models is markedly non-Gaussian at 1. 3 mm but is straightforward to calculate and depends only weakly on the assumed model for the wandering of the magnetic field direction.
