In a method for instant messaging using a control device, a user is authenticated with an instant messenger server. The semiconductor device includes a first circuit and a switch that controls conduction between an input terminal and the first circuit. Each molecular wire is bound, at one end, to the conductive nanoparticle and, at the opposed end, to one of a pair of electrodes. Latch and ramp portions of clips cooperate with the respective fasteners to draw the end-caps into a close locking engagement with the appliance door. The process includes peening of the article, optionally followed by an annealing treatment. In one embodiment the method includes the step of inserting a guide wire into the upper gastrointestinal tract, via a gastric opening in the gastric wall and an abdominal opening in the abdominal wall of the patient, the guide wire having a first end that extends from the mouth of the patient, and a second end that extends from the abdominal opening of the patient.
