Mortality trends and differentials in South Africa from 1997 to 2012: second National Burden of Disease Study

The Lancet Global Health, 2016
Background: The poor health of South Africans is known to be associated with a quadruple disease burden. In the second National Burden of Disease (NBD) study, we aimed to analyse cause of death data for 1997–2012 and develop national, population group ...

Stationary Rotating Strings as Relativistic Particle Mechanics [PDF]

, 2008
Stationary rotating strings can be viewed as geodesic motions in appropriate metrics on a two-dimensional space. We obtain all solutions describing stationary rotating strings in flat spacetime as an application.

Model Reduction Near Periodic Orbits of Hybrid Dynamical Systems [PDF]

, 2015
We show that, near periodic orbits, a class of hybrid models can be reduced to or approximated by smooth continuous-time dynamical systems. Specifically, near an exponentially stable periodic orbit undergoing isolated transitions in a hybrid dynamical ...

Estimating the changing burden of disease attributable to low levels of physical activity in South Africa for 2000, 2006 and 2012

South African Medical Journal, 2022
Background. Physical activity is associated with a lower risk of cardiovascular outcomes, certain cancers and diabetes. The previous South African Comparative Risk Assessment (SACRA1) study assessed the attributable burden of low physical activity for ...
