A hybrid cytokine comprising the B-chain of hepatocyte growth factor and IL-7, linked by a linker molecule, having pre-pro-B growth stimulating activity. The circuit comprises a coupling circuit that provides capacitance or electromagnetic coupling to pass an externally-derived stream of pulses to a microprocessor therein by either, in the case of capacitance coupling, connecting an external device that generates the stream of externally-derived of pulses to a valve stem of the tire and an electrical ground. Further aspects of the invention relate to methods of making and using such compositions of the invention, as well as articles and kits associated with the compositions. A single level shifter can be connected to multiple driver modules, thereby reducing the area required to implement level-shifting for multiple word-lines. A first refrigerant passage extends from the flow adjustment part to the first evaporator, and a second refrigerant passage extends from the flow adjustment part to the second evaporator.
