Associations of mortality with own height using son's height as an instrumental variable

A variable height "wobble board".

The "wobble board" has been used for many years for the re-education of the musculature of the ankle and foot after injury. Varying heights of board have been used depending on the range of movement required at various stages of recovery but I have not seen, nor have some experienced colleagues seen, one where the height is adjustable. Such a device is here illustrated. It consists of a circula...

Exploring the Developmental Overnutrition Hypothesis Using Parental–Offspring Associations and FTO as an Instrumental Variable

BACKGROUND The developmental overnutrition hypothesis suggests that greater maternal obesity during pregnancy results in increased offspring adiposity in later life. If true, this would result in the obesity epidemic progressing across generations irrespective of environmental or genetic changes. It is therefore important to robustly test this hypothesis. METHODS AND FINDINGS We explored this...

Three-dimensional bin packing problem with variable bin height

This paper studies a variant of the three-dimensional bin packing problem (3D-BPP), where the bin height can be adjusted to the cartons it packs. The bins and cartons to be packed are assumed rectangular in shape. The cartons are allowed to be rotated into any one of the six positions that keep the carton edges parallel to the bin edges. This greatly increases the difficulty of finding a good s...
