Heritability of clubfoot: A twin study [PDF]
Journal of Children's Orthopaedics, 2014 Introduction The aetiology of congenital clubfoot is unclear. Although studies on populations, families, and twins suggest a genetic component to the aetiology, other studies have identified environmental factors. The purpose of this study was to calculate heritability in order to determine to what extent genetic and/or environmental factors contribute

Children of the Twins Early Development Study (CoTEDS): A Children-of-Twins Study [PDF]
Twin Research and Human Genetics, 2019 The Children of the Twins Early Development Study (CoTEDS) is a new prospective children-of-twins study in the UK, designed to investigate intergenerational associations across child developmental stages. CoTEDS will enable research on genetic and environmental factors that underpin parent-child associations, with a focus on mental-health and cognitive

Unzipping flux lines from extended defects in type-II superconductors
, 2005 With magnetic force microscopy in mind, we study the unbinding transition of individual flux lines from extended defects like columnar pins and twin planes in type II superconductors. In the presence of point disorder, the transition is universal with an
