When you know this, “Then you start seeing the world in a different way.” This evolutionary connection fueled the artist’s imagination as well as his interest in the natural world and its origins, which rivals only his compul...

GPS Trajectory Biometrics: From Where You Were to How You Move

In this paper, we study how well GPS data can be used for biometric identification. Previous work has considered only the location and the entire route trajectory pattern. These can reveal the user identity when he repeats his every day moving patterns but not when traveling to new location where no route history is recorded for him. Instead of the absolute location, we model location-independe...

Causes of Inequality in Health: Who You Are? Where You Live? Or Who Your Parents Were?

Amongst 33-year olds in the UK National Child Development Study (NCDS), ill health (as measured by cardinalised responses to a question on self-assessed health) is concentrated amongst the worse off. We seek to decompose these inequalities in ill health into their socioeconomic causes. In this decomposition, inequalities in health status depend on inequalities in each of the underlying determin...

Explosive eruptions, like the ancient events at Mount Vesuvius in Italy and the modern ones...
