The positioning control of the hydraulic support pushing system in the fully mechanized mining face is the key technical support to realize intelligent mining.The opening and closing of the existing support switch reversing valve will cause a sudden change in the system pressure and flow under the conditions of high pressure and large flow, which w

The action potential forms the basis of cardiac pacemaking, conduction, and contraction.Action potentials can be recorded from numerous preparation types, including ventricular or atrial trabecules, Purkinje fibers, isolated cardiac myocytes.Numerous techniques are also available as well, such as the conventional microelectrode and the single-cell
