Your mass will stay the same wherever you go in the universe but your weight will fluctuate depending on the mass and position of the objects around you.
They utilized the stream made by the oscillating bubbles, which can control the position of the objects.
The problem considered here is that of identifying shape and position of the objects on the sole basis of measurements on the external boundary of the domain.
With these matrices we were finally able to calculate the real position of the objects in the arena from the pixel coordinates derived from the recordings.
Paired Students t-test was used to analyse whether there was a significant difference in time spent exploring the novel and familiar objects and the novel and familiar position of the objects within each genotypic group and the wildtype mice.
This is equivalent to a decrease of 0.87 Pearson r units—a dramatic decorrelation in the spatial pattern of activity, despite a tiny change in the position of the objects.
