Efficient coupling of within- and between-host infectious disease dynamics

no code implementations18 Dec 2023 Cameron A. Smith, Ben Ashby

Various approaches have been proposed to model both within- and between-host dynamics, but these typically require considerable simplifying assumptions to couple processes at contrasting scales (e. g., the within-host dynamics quickly reach a steady state) or are computationally intensive.

Critical weaknesses in shielding strategies for COVID-19

1 code implementation15 Sep 2021 Cameron A. Smith, Christian A. Yates, Ben Ashby

An alternative and widely discussed public health strategy for the COVID-19 pandemic would have been to 'shield' those most vulnerable to COVID-19 (minimising their contacts with others), while allowing infection to spread among lower risk individuals with the aim of reaching herd immunity.

Adaptive modelling of variably saturated seepage problems

no code implementations11 Jan 2021 Ben Ashby, Cassiano Bortolozo, Alex Lukyanov, Tristan Pryer

In this article we present a goal-oriented adaptive finite element method for a class of subsurface flow problems in porous media, which exhibit seepage faces.
