Abstract: Provided are a phosphorescent organometallic complex and a use thereof. The metal complex has a ligand with a structure represented by Formula 1 and may be used as a light-emitting material in an electroluminescent device. These novel metal complexes can not only maintain low voltage and improve device efficiency in electroluminescent devices but also greatly reduce the half-peak width of light emitted by these devices so as to greatly improve color saturation of the light emitted by these devices, thereby providing better device performance. Further provided are an electroluminescent device and a compound formulation.

Abstract: A level shifter circuit uses standard n-channel and p-channel transistors except for a pair of Lateral-Diffusion Metal-Oxide-Semiconductor (LDMOS) transistors that have an added lateral diffusion under the gate between the source and the conduction channel, increasing the breakdown voltage. The source of each LDMOS transistor connects to a drain of a transient differential transistor that has its gate driven by a oneshot that generates a pulse after an input transition. After the pulse ends a holding differential transistor draws a smaller bias current from the LDMOS transistors. The source of each LDMOS transistor connects to the drain and gate of a p-channel sensing transistor that drives gates of mirror transistors generating mirrored currents to cross-coupled n-channel mirror transistors that drive both terminals of a bistable latch that holds the output using a floating ground between driver transistors of a Buck converter switched by the bistable latch.

Abstract: An exhaust gas mixer arrangement for mixing exhaust gases of an internal combustion engine with an additive comprises an exhaust gas flow duct (28) with an inlet area (24) arranged upstream and with a discharge area (26) arranged downstream. The exhaust gas flow duct (28) is bent in a coil-like manner at least in some areas between the inlet area (24) and the discharge area (26).

Abstract: Disclosed is a method for producing three-line hybrid wheat parent foundation seeds, including: determining whether sterile-line head progeny rows satisfy 100% sterile degree index of a sterile line or not by bagged selfing of the sterile-line head progeny rows, separately harvesting the bagged outcrossed heads satisfying the index to achieve cyclic breeding of sterile-line spike lines, and mixedly harvesting the sterile-line head progeny rows satisfying the index for sterile-line foundation seed plots; conducting test crossing on the separately harvested bagged outcrossed head seeds and the restorer-line head progeny rows, correspondingly numbering the restorer-line head progeny rows and bagged test-crossed heads, and separately harvesting bagged test-crossed seeds; conducting yield comparison on the separately harvested bagged test-crossed seeds, taking a part of preserved restorer-line head progeny row seeds meeting the requirement for cyclic breeding of restorer-line spike lines, and then planting the res
