According to some embodiments, a device is configured to perform a dual multiply-accumulate operation. In one embodiment of the present invention, the arrangement comprises a split fastening ring and a split O-ring support member. According to the present method the living tissue is subjected to electric field conditions sufficient to cause movement of the polarizable intracellular members toward the cleavage furrow in response to a non-homogenous electric field being induced in the dividing cells.
