In a turbine engine with an annular recuperator surrounding the turbine, exhaust gas is directed from the turbine to the recuperator by a generally curved exhaust dome. In another mode, the application responds based upon its own current state and the state of a second application. In this way, a UE can make full use of the padding bits of the obtained multiple TBs, and report the buffer status flexibly. In an implementation, two wafers are prepared and then bonded together to form a structure. When N<NMAX, lines not carrying functional data are partially powered down between calibrations.
