A composite modular energy absorbing assembly with one or more gamma structures 100 that are interposed with one or more delta structures 200. The apparatus includes a first mandrel and a second mandrel that inserts into and is axially moveable within the first mandrel. The compositemetal shaft subset preferably includes the middle irons with medium lofts such as the five, six, and seven iron shafts. There are various ways to determine the relative distance between the target and the device. The item listing is utilized for posting with a listing manager. The low conductivity region increases the effective width of the tunnel barrier, making electrons tunnel a greater distance, which reduces the memory element’s conductivity.
