• #### Density Estimation by Monte Carlo and Quasi-Monte Carlo ﻿

(2021)
Estimating the density of a continuous random variable $X$ has been studied extensively in statistics, in the setting where $n$ independent observations of $X$ are given a priori and one wishes to estimate the density from ...
• #### Deterministic and Stochastic Dynamics of COVID-19: The Case Study of Italy and Spain ﻿

(2022-02-13)
In December 2019, a severe respiratory syndrome (COVID-19) caused by a new coronavirus (SARS-CoV-2) was identified in China and spread rapidly around the globe. COVID-19 was declared a pandemic by the World Health Organization ...
• #### Discretizations of the spectral fractional Laplacian on general domains with Dirichlet, Neumann, and Robin boundary conditions ﻿

(2017-04-28)
In this work, we propose novel discretisations of the spectral fractional Laplacian on bounded domains based on the integral formulation of the operator via the heat-semigroup formalism. Specifically, we combine suitable ...
• #### Dynamic modeling of the morphology of latex particles with in situ formation of graft copolymer ﻿

(2012-12-31)
Modification of the polymer-polymer interfacial tension is a way to tailor-make particle morphology of waterborne polymer-polymer hybrids. This allows achieving a broader spectrum of application properties and maximizing ...
• #### Dynamic modeling of the morphology of multiphase waterborne polymer particles ﻿

(2013-12-31)
Multiphase waterborne polymer particles provide advantages in more demanding applications, and their performance depends on particle morphology. Currently, no dynamic model for the prediction of the development of the ...
• #### Effect of General Cross-Immunity Protection and Antibody- Dependent Enhancement in Dengue Dynamics ﻿

(2022-02-13)
A mathematical model to describe the dynamic of a multiserotype infectious disease at the population level is studied. Applied to dengue fever epidemiology, we analyse a mathematical model with time delay to describe the ...
• #### Effect of Tissue Elasticity in Cardiac Radiofrequency Catheter Ablation Models ﻿

(2018)
Radiofrequency catheter ablation (RFCA) is an effective treatment for different types of cardiac arrhythmias. However, major complications can occur, including thrombus formation and steam pops. We present a full 3D ...
• #### Electrochemical Potential Derived from Atomic Cluster Structures ﻿

(2016-01-01)
Based on the atomic cluster structures and free electron approximation model, it is revealed that the electrochemical potential (ECP) for the system of interest is proportional to the reciprocal of atomic cluster radius ...
• #### Enhancing sampling in atomistic simulations of solid state materials for batteries: a focus on olivine NaFePO$_4$ ﻿

(2017-03-07)
The study of ion transport in electrochemically active materials for energy storage systems requires simulations on quantum-, atomistic- and meso-scales. The methods accessing these scales not only have to be effective but ...
• #### Enhancing Sampling in Computational Statistics Using Modified Hamiltonians ﻿

(2016-11-15)
The Hamiltonian Monte Carlo (HMC) method has been recognized as a powerful sampling tool in computational statistics. In this thesis, we show that performance of HMC can be dramatically improved by replacing Hamiltonians ...
• #### Estimation of age-specific rates of reactivation and immune boosting of the varicella zoster virus ﻿

(2016-12-31)
Studies into the impact of vaccination against the varicella zoster virus (VZV) have increasingly focused on herpes zoster (HZ), which is believed to be increasing in vaccinated populations with decreasing infection pressure. ...
• #### Ethics of a partially effective dengue vaccine: Lessons from the Philippines ﻿

(2020-07)
Dengvaxia, a chimeric yellow fever tetravalent dengue vaccine developed by SanofiPasteur is widely licensed in dengue-endemic countries. In a large cohort study Dengvaxia was found to partially protect children who had ...
