Comparing the performance of three generations of ActiGraph accelerometers.
ActiGraph accelerometers are a useful tool for objective assessment of physical activity in clinical and epidemiological studies. Several generations of ActiGraph are being used; however, little work has been done to verify that measurements are consistent across generations. This study employed mechanical oscillations to characterize the dynamic response and intermonitor variability of three g...
متن کاملInfluences on childhood height: comparing two generations in the 1958 British birth cohort.

متن کاملOn Generations
The well known operator ordering ambiguity could motivate the existence of generations. This possibility is explored by exploiting the relationship between ordering and discretization rules. 1 Wilson fermion as analogy Non Commutative Geometry is not the only area knowing how to get mass terms from nowhere. Lattice theorists learnt time ago a nice trick from Wilson. Consider the forward and bac...
