An electrical connector includes a conductive shell having a chamber and having a mating end and a cable end. The cyclic substrate only weakly binds to the enzyme acceptor fragment of \u03b2-galactosidase. When the lower mov-able contact is positionally fixed to the body, the pressed portion is pressed from the upper side by fixing structure for the upper movable contact, and the lower movable contact is positionally fixed. R6 is a protecting group, an amidoalkyl, an alkyl, an alkyl ketone, an alkenyl, an alkynyl, a cycloalkyl, an aryl, or an aralkyl. The magnitude of the initial program pulse for the current stage being performed is dynamically set as a function of the number of program pulses used for the same stage of the multi-stage programming process when programming non-volatile storage elements connected to on one or more previously programmed word lines.
