Abstract: Solar cells having emitter regions composed of wide bandgap semiconductor material are described. In an example, a method includes forming, in a process tool having a controlled atmosphere, a thin dielectric layer on a surface of a semiconductor substrate of the solar cell. The semiconductor substrate has a bandgap. Without removing the semiconductor substrate from the controlled atmosphere of the process tool, a semiconductor layer is formed on the thin dielectric layer. The semiconductor layer has a bandgap at least approximately 0.2 electron Volts (eV) above the bandgap of the semiconductor substrate.

Abstract: One implementation of the present disclosure is a system including one or more memory devices having instructions stored thereon, that, when executed by one or more processors, cause the one or more processors to receive a selection including a context and a twin function and generate an operation to monitor a graph based on the context, the operation identifying whether one or more new events are added to the graph, the one or more new events affecting a processing result. The instructions cause the one or more processors to cause the twin function to execute responsive to identifying the one or more new events added to the graph that affect the processing result, execute the twin function based on the one or more new events and the context to generate the processing result.

Abstract: Inexpensive and reliable apparatus for blanking the signal path between an antenna and a transmitter or a receiver to protect them from harmful radiation in the absence of power forms supplied thereto. The apparatus is preferably formed as a printed circuit waveguide switch window having a plurality of parallel conductors, such as metal wires or printed circuit traces, disposed on a dielectric substrate. The waveguide switch window is secured between two sections of waveguide. The conductors have a predetermined separation and width that are designed to appear as a solid metal surface that rejects radiation over a wide bandwidth. A bias terminal is coupled to the plurality of conductors, and insulating material is disposed between the bias terminal and the conductors to insulate the top portion of the grid array from the adjacent waveguide. The lower portion of the grid array is grounded to the adjacent waveguide.

Abstract: This invention relates to a heteromultimer and its use in screening pharmaceutically active compounds for modulators of maxi-K channel activity. Such modulators are useful in treating asthma, pregnant human myometrium, hypertension and angina, cerebral ischemia and in conditions where stimulation of neurotransmitter release is desired such as Alzheimer's disease and stimulation of damaged nerves.

Abstract: A millimeter wave device having a dielectric substrate with a pair of substantially parallel planar surfaces with at least one predetermined millimeter wave circuit pattern formed in a conductive layer located on at least one of the substrate surfaces. A substantially planar conductive channel plate is mounted adjacent the conductive layer on one substrate surface with the channel plate having an aperture overlying each circuit pattern formed in the conductive layer. A substantially planar conductive cover plate is mounted adjacent one of the channel plates so as to form a first cavity in the region defined by the substrate surface, the channel plate aperture and the cover plate The device may further include a second substantially planar conductive channel plate mounted adjacent the other one of the substrate surfaces with the second channel plate having an aperture corresponding to and aligned with the first channel plate aperture.

Abstract: Disclosed are nucleic acids encoding the .beta. subunit of the mammalian large-conductance ("maxi-K") potassium channel, cells transformed with such nucleic acids, and .beta. subunit proteins produced by the transformed cells. Within the invention are recombinant host cells expressing .alpha..beta. heteromultimers. Such cells or preparations made from them may be used to screen for pharmacologically active modulators of maxi-K channel activity. Such modulators are potentially useful in treating asthma, pregnant human myometrium, hypertension and angina, cerebral ischemia, and conditions where stimulation of neurotransmitter release is desired, such as in Alzheimer's disease and stimulation of damaged nerves.
