It is also a reminder that reliable (i.e. reproducible) optimization requires efforts to ensure that the subtle signal of between-setting differences is not obscured by spontaneous beat-to-beat biological variability.
Joanie, a fussy Wasp, fears that she's chosen pregnancy for the "wrong reason" - whether to beat her biological timeclock or as a substitute for her failed painting career or as a panacea for marital ills.
She described Barker as a violent woman who beat her biological daughter with a belt and who ultimately "whooped and whooped and whooped on Viola," killing her.
Torres, well aware of such concerns in an era where doping has tainted too many sports, has submitted to extra drug testing in an attempt to prove beyond a reasonable doubt that she is beating the biological clock fairly.
Notably, in order to measure these changes with confidence it was necessary to make numerous replicate measurements to allow the subtle effects of pacemaker timing adjustment to be identified from biological beat-to-beat variability.
Family genetic history, data on how they digest food, how they react to drugs, how fast their hearts beat and other biological data will be collected and collated.
Personified is an opportunity to experience the cutting-edge interfaces used for both the plant-sonification and Fox's investigation into biological beats and rhythms.
We note that it would in fact be extremely challenging to acquire an equivalent dataset in a fixed specimen: in a dead organism the heart will tend to collapse into a shape different to its natural shape when beating, reducing the biological usefulness of the images for functional analysis.
Even if these factors are controlled, blood pressure is subject to biological variation from beat to beat, minute to minute, and day to day.
Inter- and intra-observer variability may not be the dominant source of noise, rather there may well be genuine biological variation between beats.
The midwife placed the ultrasound wand near the boy's shoulder, and the beating heart emerged: my husband's biological child in another woman's body.
