Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Advanced Engineering Materials, EarlyView.Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

General Relativity from Causality
, 2017 We study large families of theories of interacting spin 2 particles from the point of view of causality. Although it is often stated that there is a unique Lorentz invariant effective theory of massless spin 2, namely general relativity, other theories ...

Minimal wave speed of a nonlocal diffusive epidemic model with temporal delay
Rocky Mountain Journal of Mathematics, 2014 This paper is concerned with the traveling wave solutions of an epidemic model with nonlocal dispersal and time delay. By a characteristic equation, a threshold is defined. If the wave speed is larger than the threshold, the existence of traveling wave solutions is proved by combining upper-lower solutions with monotone iteration.

Slow and fast minimal speed traveling waves of the FKPP equation with chemotaxis
Journal de Mathématiques Pures et Appliquées, 2022 We examine a general model for the Fisher-KPP (FKPP) equation with nonlocal advection. The main interpretation of this model is as describing a diffusing and logistically growing population that is also influenced by intraspecific attraction or repulsion.

Inflation from a nonlinear magnetic monopole field nonminimally coupled to curvature
, 2018 In the context of nonminimally coupled $f(R)$ gravity theories, we study early inflation driven by a nonlinear monopole magnetic field which is nonminimally coupled to curvature.

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion
Advanced Engineering Materials, EarlyView.This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

Modeling and Simulating an Epidemic in Two Dimensions with an Application Regarding COVID-19
ComputationWe derive a reaction–diffusion model with time-delayed nonlocal effects to study an epidemic’s spatial spread numerically. The model describes infected individuals in the latent period using a structured model with diffusion.
