A semiconductor device includes first and second semiconductor regions, and a third semiconductor region between the first and second semiconductor regions, wherein the dopant concentration of the third semiconductor region is greater than the dopant concentration of the second semiconductor region. A machine includes: a body; a plurality of bays in the body, wherein each bay is configured to receive a respective module; and a power source carried by the body. The first wireless network suspends allocation of radio resources to the mobile wireless device based on receipt of a suspension message from the mobile wireless device, or based on knowledge of a paging cycle for mobile wireless device in the second wireless network, or based on detection of an out of synchronization condition with the mobile wireless device. The storage phosphor assembly comprises an insert plate having a first and second side, a back end member having two ends, and a first and second edge insert. A drive belt transmits torque from the output shaft to the flywheel so as to rotate the flywheel upon rotation of the output shaft. Once these are determined, an MIP solver would generate an optimized bit sequence.
