Nonlinearity, 2004
Summary: Ecological vector fields \(\dot x_j= x_if_i(x)\) on the nonnegative cone \(\mathbb{R}^n_+\) on \(\mathbb{R}^n\) are often used to describe the dynamics of \(n\) interacting species. These vector fields are called permanent (or uniformly persistent) if the boundary \(\partial\mathbb{R}^n_+\) of the nonnegative cone is repelling. We construct an

The Persistent Mystery of Adenovirus Persistence
Trends in Microbiology, 2016Human adenovirus (HAdV) often causes acute, lytic infections which are readily recapitulated in culture models. Alternatively, HAdV can establish persistent infections which have been difficult to reproduce in cell culture and are poorly understood. A recent study reveals how HAdV can re-task the host cell antiviral response to establish persistence.

The Persistence Space in Multidimensional Persistent Homology
2013Multidimensional persistent modules do not admit a concise representation analogous to that provided by persistence diagrams for real-valued functions. However, there is no obstruction for multidimensional persistent Betti numbers to admit one. Therefore, it is reasonable to look for a generalization of persistence diagrams concerning those properties ...

Persistent Problems with Persistent Herpesviruses
New England Journal of Medicine, 1981Persistent infections occur with all the human herpesviruses: herpes simplex virus (HSV) Types 1 and 2, cytomegalovirus (CMV), varicella zoster virus (VZV), and Epstein–Barr virus (EBV).
