A network-based model to assess vaccination strategies for the COVID-19 pandemic by using Bayesian optimization

González Parra, Gilberto Carlos; Villanueva-Oller, Javier; Navarro-González, F. J.; Ceberio, Josu; Luebben, Giulia (Elsevier, 2024-04)

[EN] In this paper we build a network-based model to evaluate and compare vaccination plans in order to find the optimal strategies. The age-structured model is designed to take into account the comorbidity status and ...
Analysis of Key Factors of a SARS-CoV-2 Vaccination Program: A Mathematical Modeling Approach

Martínez-Rodríguez, David; González Parra, Gilberto; Villanueva Micó, Rafael Jacinto (MDPI AG, 2021-04-01)

[EN] The administration of vaccines against the coronavirus disease 2019 (COVID-19) started in early December of 2020. Currently, there are only a few approved vaccines, each with different efficacies and mechanisms of ...
Analytical Solutions of Systems of Linear Delay Differential Equations by the Laplace Transform: Featuring Limit Cycles

Kerr, Gilbert; Lopez, Nehemiah; González Parra, Gilberto Carlos (MDPI AG, 2024-02)

[EN] In this paper we develop an approach for obtaining the solutions to systems of linear retarded and neutral delay differential equations. Our analytical approach is based on the Laplace transform, inverse Laplace ...
Dinámica del virus pandémico AH1N1/09 en la población de Venezuela

González Parra, Gilberto Carlos; Villanueva Micó, Rafael Jacinto; Segovia, Lupe (Interciencia Association, 2012-04)

[EN] The dynamics of the prevalence of the pandemic virus AH1N1/09 in Venezuela, between May and December 2009, is of interest and not easily predictable. The dynamics at the population level of the AH1N1/09 virus and their ...
Existence of Traveling Waves of a Diffusive Susceptible-Infected-Symptomatic-Recovered Epidemic Model with Temporal Delay

Miranda, Julio C.; Arenas, Abraham J.; González-Parra, Gilberto; Villada, Luis Miguel (MDPI AG, 2024-03)

[EN] The aim of this article is to investigate the existence of traveling waves of a diffusive model that represents the transmission of a virus in a determined population composed of the following populations: susceptible ...
Impact of a New SARS-CoV-2 Variant on the Population: A Mathematical Modeling Approach

González Parra, Gilberto; Martínez-Rodríguez, David; Villanueva Micó, Rafael Jacinto (MDPI AG, 2021-03-27)

[EN] Several SARS-CoV-2 variants have emerged around the world, and the appearance of other variants depends on many factors. These new variants might have different characteristics that can affect the transmissibility and ...
Mathematical modeling of childhood obesity from a social epidemic point of view for the spanish region of Valencia: numerical and analytical solutions

González Parra, Gilberto Carlos (Universitat Politècnica de València, 2009-10-22)

This thesis dissertation deals with the mathematical modeling of childhood obesity from a social epidemic point of view for the Spanish region of Valencia. Three mathematical models based on systems of nonlinear ordinary ...
Matrix Nonstandard Numerical Schemes for Epidemic Models

González Parra, Gilberto Carlos; Villanueva Micó, Rafael Jacinto; Arenas Tawil, Abraham José (World Scientific and Engineering Academy and Society (WSEAS), 2010-11)

This paper is concerned with the construction and developing of several nonstandard finite difference (NSFD) schemes in matrix form in order to obtain numerical solutions of epidemic models. In particular, we deal with a ...
Modeling population uncertainty using statistical moments

González Parra, Gilberto Carlos; Cortés, J.-C.; Villanueva Micó, Rafael Jacinto; Santonja, Francisco José (Sociedad de Estadística e Investigación Operativa, 2012-10)

[EN] In this paper a random differential equation system modeling population dynamics is investigated by means of the statistical moments equation. Monte Carlo simulations are performed in order to compare with the statistical ...
Modelling influenza A(H1N1) 2009 epidemics using a randomnetwork in a distributed computing environment

González Parra, Gilberto Carlos; Villanueva Micó, Rafael Jacinto; Ruiz Baragaño, Javier; Moraño Fernández, José Antonio (Elsevier, 2015-03)

In this paper we propose the use of a random network model for simulating and understanding theepidemics of influenza A(H1N1). The proposed model is used to simulate the transmission process ofinfluenza A(H1N1) in a community ...
Solving Allen-Cahn equations with periodic and nonperiodic boundary conditions using mimetic finite-difference operators

Orizaga, Saulo; González Parra, Gilberto Carlos; Forman, Logan; Villegas-Villanueva, Jesús (Elsevier, 2025-01-01)

[EN] In this paper, we investigate and implement a numerical method that is based on the mimetic finite difference operator in order to solve the nonlinear Allen-Cahn equation with periodic and non-periodic boundary ...
