Their study in the journal Geophysical Research Letters used a technique called radar interferometry, which measures changes between the satellite instrument and the ground.
A metric, called the similarity index, was devised to measure changes between successive OCA images in the stack (separated by 1 week) in the maximum projection plane at a depth closest to the electrode tip (300-400 µm below the window).
By precisely measuring changes in distance between twin spacecraft orbiting the moon, she and other scientists hope to answer fundamental questions about the moon's evolution and internal composition.
By precisely measuring changes in distance between the twin orbiting spacecraft, scientists will construct a detailed gravitational model of the moon that will be used to answer fundamental questions about the moon's evolution and its internal composition.
In solution, the action of molecular rotors is typically characterized by NMR, measuring changes in coupling between nuclei in the rotor as their proximities change due to rotation.
The measurement can be performed indirectly, e.g. by measuring changes in electrical resistance between the workpiece and the drill bit at the moment of the touch.
By measuring changes in the ratio between the cyan and yellow signal, the possible pathway-specific cytotoxicity of each compound could be determined.
Therefore, to test the idea of protomer segregation more directly we measured changes in BRET between β2AR-Rluc8 and the venus-labeled acceptor β2AR-V (and binding defective mutants of these receptors) due to stimulation with isoproterenol (Figure 4A).
In our study, we measured changes in gene expression between consecutive time points, specifically between 10 to 20, 20 to 40 and 40 to 60 DAA.
To achieve the mission's science goals, the two probes, which can travel more than 200 kilometers apart, needed to be able to measure changes in the distance between them to within a few tenths of a micron per second.
