Threshold Dynamics of a Huanglongbing Model with Logistic Growth in Periodic Environments
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.

Assessment of the Variational Quantum Eigensolver: Application to the Heisenberg Model
We present and analyze large-scale simulation results of a hybrid quantum-classical variational method to calculate the ground state energy of the anti-ferromagnetic Heisenberg model.

The Achaemenid Expansion to the Indus and Alexander’s Invasion of North-West South Asia [PDF]
There is a range of evidence that informs us about the organisation of the Achaemenid Empire, but our understanding ofthe eastern-most reaches of the empire, which lie within the bounds of modern-day Pakistan is relatively limited. Whilethere is evidence

On a Stochastic SEIS Model with Treatment Rate of Latent Population
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]
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 ...

Fast Gaussian Process Emulation of Mars Global Climate Model
The NASA Ames Mars Global Climate Model (MGCM) software has been in steady use at NASA for decades and was recently released to the public. This model simulates the complex interactions of various weather cycles that exist on Mars, namely the Dust Cycle,
