Asymptotic Analysis of discrete nonlinear localised modes in a Kagome lattice

Jonathan AD Wattis, Pilar R Gordoa, Andrew Pickering

We describe a nonlinear kagome lattice with nonlinear dynamics described by Klein-Gordon interactions with a scalar unknown at each node, such as might occur in a nonlinear electri…

Analysis of Genotype-Phenotype Association using Genomic Informational Field Theory (GIFT)

Jonathan Wattis, Sian Bray, Panagiota Kyratzi +1

We show how field- and information theory can be used to quantify the relationship between genotype and phenotype in cases where phenotype is a continuous variable. Given a sample…

Breather modes of fully nonlinear mass-in-mass chains

Jonathan AD Wattis

We propose a model for a chain of particles coupled by nonlinear springs in which each mass has an internal mass and all interactions are assumed to be nonlinear. We show how to co…

Modelling COVID-19 Transmission Dynamics in Ghana

Edward Acheampong, Eric Okyere, Samuel Iddi +3

In late 2019, a novel coronavirus, the SARS-CoV-2 outbreak was identified in Wuhan, China and later spread to every corner of the globe. Whilst the number of infection-induced deat…

Stochastic Fractal and Noether's Theorem

Rakibur Rahman, Fahima Nowrin, M. Shahnoor Rahman +2

We consider the binary fragmentation problem in which, at any breakup event, one of the daughter segments either survives with probability or disappears with probability $1\!-\…

The effects of competition between random sequential nucleation of point-sized seeds and island growth by adsorption of finite-sized grains

A. Khanam, J. A. D. Wattis, M. K. Hassan

We study random sequential adsorption of particles from pool onto a one dimensional substrate following ballistic deposition rules, with separate nucleation and growth processes oc…
