CAD model of the #tricycle subframe. The chain ring is very nearly as big as the front wheel (80 teeth!). It drives an epicyclic gearbox mounted in the nose of the vehicle, which also has a disc brake. The epicyclic will drive a secondary chain via a sprocket mounted to the left hand spoke flange, but this is not yet shown. There will be no ratchet on the secondary chain, so the disk brake on the…

Temporal Exposure Dependence Bias in Vaccine Efficacy Trials
Using time-to-event methods such as Cox proportional hazards models, it is well established that unmeasured heterogeneity in exposure or infection risk can lead to downward bias in point estimates of the per-contact vaccine efficacy (VE) in infectious disease trials. In this study, we explore an unreported source of bias-arising from temporally correlated exposure status-that is typically unmeasured and overlooked in standard analyses. Although this form of bias can plausibly affect a wide rang…
