Abstract: A reduction in wake effects in large wind farms through wake-aware control can improve farm efficiency. The wake of a wind turbine presents complications for nearby turbines, depending on the atmospheric conditions, turbine characteristics, and turbine siting. The nascent field of wind farm flow control seeks to reduce the deleterious effects of the wake momentum deficit by leveraging the turbine as a flow actuator though the intelligent scheduling of either the blade pitch, rotor speed, or nacelle yaw.

Abstract: The present invention concerns methods of reducing the antigenicity of a proteinaceous compound while maintaining the compounds biological activity, as well as proteinaceous compositions with biological activity but reduced antigenicity. These methods and compositions have significant benefits to a subject in need of such compounds and compositions. Also included are modified toxin compounds that are truncated and/or possess reduce antigenicity. Such designer toxins have therapeutic, diagnostic, and preventative benefits, particularly as immunotoxins. Methods of treating cancer using these immunotoxins are provided.

Abstract: A flat panel x-ray imager exhibiting reduced ghosting effects and overvoltage protection by appropriate leakage current characteristics of the thin-film transistor array. A top electrode of a suitable material is directly on an amorphous selenium-based charge generator layer allowing charge transport across the layer, thereby reducing ghosting. Alternatively, a non-insulating organic layer may be between the top electrode and the charge generating layer. The thin-film transistors have leakage current that rises relatively slowly with voltage across the transistor within a range that matches exposure through an object being imaged but rises at a sufficiently higher rate within a higher range to provide protection even when a corresponding region of the charge generator layer receives greater amounts of x-rays. A voltage is applied to the top electrode. This voltage may be within the range of 500 V to 2,000 V.
