Stability of Global Monopoles Revisited [PDF]
Physical Review Letters, 2000 We analyze the stability of global O(3) monopoles in the infinite cutoff (or scalar mass) limit. We obtain the perturbation equations and prove that the spherically symmetric solution is classically stable (or neutrally stable) to axially symmetric, square integrable, or power-law decay perturbations.

Mathematical analysis of a two-tiered microbial food-web model for the anaerobic digestion process
Mathematical Biosciences and Engineering, 2023 In this research paper, we presented a four-dimensional mathematical system modeling the anaerobic mineralization of phenol in a two-step microbial food-web. The inflowing concentrations of the hydrogen and the phenol are considered in our model.

Modeling Citrus Huanglongbing transmission within an orchard and its optimal control
Mathematical Biosciences and Engineering, 2020 Citrus Huanglongbing (HLB) is the most devastating citrus disease worldwide. In this paper, a deterministic dynamical model is proposed to explore the transmission dynamics of HLB between citrus tree and Asian citrus psyllid (ACP).

Truss geometry and topology optimization with global stability constraints
Structural And Multidisciplinary Optimization, 2020 In this paper, we introduce geometry optimization into an existing topology optimization workflow for truss structures with global stability constraints, assuming a linear buckling analysis.

Global Stability of Fluid Flows Despite Transient Growth of Energy. [PDF]
Physical Review Letters, 2019 Verifying nonlinear stability of a laminar fluid flow against all perturbations is a central challenge in fluid dynamics. Past results rely on monotonic decrease of a perturbation energy or a similar quadratic generalized energy.

Global Stability for Fractional Diffusion Equations in Biological Systems
Complex, 2020 This paper proposes a new method of construction of Lyapunov functionals for the dynamical systems described by fractional differential equations and fractional partial differential equations. The proposed method is rigorously presented. Furthermore, the
