Dynamical Lifetime Survey of Geostationary Transfer Orbits [PDF]
Celest Mech Dyn Astr (2018) 130: 77, 2019 In this paper, we study the long-term dynamical evolution of highly-elliptical orbits (HEOs) in the medium-Earth orbit (MEO) region around the Earth. The real population consists primarily of Geosynchronous Transfer Orbits (GTOs), launched at specific inclinations, Molniya-type satellites and related debris.

The Dynamics of Sustained Reentry in a Loop Model with Discrete Gap Junction Resistance [PDF]
Phys. Rev. E. 76, 021928 (2007), 2007 Dynamics of reentry are studied in a one dimensional loop of model cardiac cells with discrete intercellular gap junction resistance ($R$). Each cell is represented by a continuous cable with ionic current given by a modified Beeler-Reuter formulation. For $R$ below a limiting value, propagation is found to change from period-1 to quasi-periodic ($QP$)

What's age got to do with it? A primer and review of the workplace aging literature
Personnel Psychology, Volume 75, Issue 4, Page 779-804, Winter 2022., 2022 Abstract As populations in the United States and around the world continue to age, it has become increasingly important to understand how organizations can create working conditions that attract, support, and retain workers across the lifespan. In this paper, we provide a primer on current theory and research on age in the workplace.
