Previous studies attempted to estimate the impedance by recording force as a result of position perturbations, but these experiments do not require a feasible task of human beings.
Molecular recognition forces are measured by recording force curves between modified tips and sample and then assessing the unbinding force between complementary receptor and ligand molecules from the adhesion force observed upon retraction.
One vessel en route from Curaçao to New York encountered the storm on two separate occasions, recording Force 8 winds on the Beaufort scale both times.
The objective of this study is to develop and validate a force logging system that can record forces at multiple locations inside a brace, as well as brace strap tension, and correlate these forces with different body positions.
Recorded forces were normalized to cross-sectional area to provide isometric tension (T).
The penetration resistance was calculated by dividing the recorded force by the bearing area of the needle.
We developed a data-acquisition system that can record force and EMG data simultaneously with fMRI signals.
It is able to record force displacement hysteresis with a resolution of better than 1 mN and 20 nm for force and displacement measurements, respectively.
The 'indirect' method (from the maximum recorded force as a function of the embedded length) and the calculation from an individual force displacement curve yielded very similar results.
