The results from single-joint elbow motion show, as predicted by the theory, that we can replicate many well-known impedance control phenomena from the first principles of optimality and conceptually explain the origins of co-contraction in volitional human reaching tasks.
This was useful in explaining the origin of High Amplitude Propagating Contractions, motor activity of the colon felt to be primarily responsible for cramping pains when high volume luminal liquid meets solid stool.
By investigating the structural differences of the prefabricated GO papers and their swelling behaviors during reduction, as well as the unlike microstructures of the obtained RGO papers, we interpreted the origin of the pH-mediated controllable contraction and mechanical performance of RGO papers.
In agreement with the origin of the tissues, the muscle contraction and the nerve cell system were the most prominently enriched biological processes in both age-positions in VL muscles and in brain cortex, respectively (Table 3).
In all the w1118 larvae (n = 60) imaged in this work, the dominant form of contraction was a peristaltic wave of caudal origin (see Movie S1).
Retrograde coronary blood flow during isovolumic ventricular contraction may be the origin of the persistent end-diastolic pressure and distension perturbation.
During cerebral vasospasm, sustained arterial contraction is at the origin of increases in the shear stress of endothelial cells and is associated with modifications of endothelial permeability, expression of adhesion molecules and myointimal proliferation [ 16, 17].
In a companion paper by the same group of researchers, Erb et al. [ 20] focuses on the contribution of non-artifactual vascular motion induced by muscle contraction to the biological origin of the same signal.
We went through a period of contraction".
The period of contraction is called systole.
That ends a run of seven quarters of contraction.
