Turing-region preservation in matrix-oriented splitting methods for reaction-diffusion systems
Angela Monti, Fasma Diele, Carmela Marangi
We develop matrix-oriented formulations of first-order splitting integrators for two-species reaction-diffusion systems on 2D domains, using the Gierer-Meinhardt system as a benchm…
Transient Instability and Patterns of Reactivity in Diffusive-Chemotaxis Soil Carbon Dynamics
Fasma Diele, Andrew L. Krause, Deborah Lacitignola +3
We study pattern formation in a chemotaxis model of bacteria and soil carbon dynamics as an example system where transient dynamics can give rise to pattern formation outside of Tu…
Patterns in soil organic carbon dynamics: integrating microbial activity, chemotaxis and data-driven approaches
Angela Monti, Fasma Diele, Deborah Lacitignola +1
Models of soil organic carbon (SOC) frequently overlook the effects of spatial dimensions and microbiological activities. In this paper, we focus on two reaction-diffusion chemotax…
Evaluating the impact of increasing temperatures on changes in Soil Organic Carbon stocks: sensitivity analysis and non-standard discrete approximation
Fasma Diele, Ilenia Luiso, Carmela Marangi +1
A novel model is here introduced for the SOC change index defined as the normalized difference between the actual Soil Organic Carbon and the value assumed at an initial reference…
Novel energy-preserving splitting integration for Hamiltonian Monte Carlo method
F. Diele, C. Marangi, C. Tamborrino +1
Splitting schemes are numerical integrators for Hamiltonian problems that may advantageously replace the Störmer-Verlet method within Hamiltonian Monte Carlo (HMC) methodology. How…
