Threshold Dynamics of a Huanglongbing Model with Logistic Growth in Periodic Environments
Abstract and Applied Analysis, 2014 We analyze the impact of seasonal activity of psyllid on the dynamics of Huanglongbing (HLB) infection. A new model about HLB transmission with Logistic growth in psyllid insect vectors and periodic coefficients has been investigated.

On a Stochastic SEIS Model with Treatment Rate of Latent Population
Abstract and Applied Analysis, 2014 The asymptotic dynamics of a stochastic SEIS epidemic model with treatment rate of latent population is investigated. First, we show that the system provides a unique positive global solution starting from the positive initial value.

Calibrate, emulate, sample [PDF]
Journal of Computational Physics, 2021 Many parameter estimation problems arising in applications are best cast in the framework of Bayesian inversion. This allows not only for an estimate of the parameters, but also for the quantification of uncertainties in the estimates. Often in such problems the parameter-to-data map is very expensive to evaluate, and computing derivatives of the map ...

Dimension reduction for Gaussian process emulation: an application to the influence of bathymetry on tsunami heights [PDF]
, 2016 High accuracy complex computer models, or simulators, require large resources in time and memory to produce realistic results. Statistical emulators are computationally cheap approximations of such simulators.
