A conjugate of a toxin and a cytokine, and a fusion protein comprising a bispecific antibody that has a first specificity for a cell marker specific to a malignant cell and a second specificity for a region of IL-15\u03b1, each optionally further comprising a radionuclide, are useful therapeutic reagents for treating leukemias and lymphomas. In one aspect, a scalable solution is achieved through a hardware interface board positioned between the network and the emulator to allow proper transfer there between. Respective first supply terminals of each Hall sensor element are connected together and to a first terminal of a common voltage source and respective second supply terminals of each Hall sensor element are connected together and to a second terminal of the common voltage source so that the common voltage source supplies an operating current for the Hall sensor elements. A conductive material layer is deposited on the back surface of the photovoltaic cell, and is patterned to form a first conductive wiring structure that electrically connects the conductive through-substrate vias and a second conductive wiring structure that provides electrical connection to the backside of the photovoltaic cell. The method, system and apparatus allow the creation of an adapter class, capable of implementing a listener interface, during runtime.
