The global stability of M33: still a puzzle [PDF]
, 2019 The inner disc of the local group galaxy M33 appears to be in settled rotational balance, and near IR images reveal a mild, large-scale, two-arm spiral pattern with no strong bar.

Stability as a natural selection mechanism on interacting networks [PDF]
, 2010 Biological networks of interacting agents exhibit similar topological properties for a wide range of scales, from cellular to ecological levels, suggesting the existence of a common evolutionary origin.

Analysis of General Humoral Immunity HIV Dynamics Model with HAART and Distributed Delays
Mathematics, 2019 This paper deals with the study of an HIV dynamics model with two target cells, macrophages and CD4 + T cells and three categories of infected cells, short-lived, long-lived and latent in order to get better insights into HIV infection within the

Mathematical Biosciences and Engineering, 2004 Explicit Lyapunov functions for SIR and SEIR compartmentalepidemic models with nonlinear incidence of the form $\beta I^p S^q$for the case $p \leq 1$are constructed. Global stability of the models is thereby established.

Global imbalances and financial stability [PDF]
Journal of Policy Modeling, 2007 Abstract There are two opposing views on global imbalances: The “traditional” view, which regards the imbalances as a threat to global economic and financial stability, and the “new paradigm” view, which considers that they are the natural consequence of economic and financial globalization. In terms of their policy implications, the traditional view

Model for hepatitis C virus transmissions
Mathematical Biosciences and Engineering, 2013 Hepatitis C virus (HCV) is a leading cause of chronic liver disease. Thispaper presents a deterministic model for HCV infection transmission and usesthe model to assess the potential impact of antiviral therapy.
