Abstract: An ionic phosphorescent metal complex has a formula of formula (I). R1 and R2 are the same or different, and are independently selected from alkyl, aryl and heteroaryl, wherein the alkyl, aryl and heteroaryl are optionally substituted with 1-5 of the following groups: halogen, alkyl, alkoxy, alkylthio, amino, alkylamino, dialkylamino, arylamino, diarylamino, haloalkyl, cyano, nitro, alkenyl, aryl and heteroaryl optionally substituted with 1-3 aryl groups; R3 is independently selected from halogen, alkyl, haloalkyl, alkoxy, alkylthio, amino, alkylamino, dialkylamino, cyano, nitro or alkenyl; M is Cu(I), Ag(I) or Au(I). The organic light-emitting diode prepared by using the phosphorescent metal complex of formula (I) as a dopant for an emissive layer is capable of achieving high-performance organic electroluminescence and is applicable to the fields of lighting and flat-panel display.

Abstract: A multi-target kinase inhibitor is shown in formula (I), in which R is selected from formula (a), formula (b), formula (c), formula (d), formula (e) and formula (f). The multi-target kinase inhibitor can effectively inhibit the enzymatic activities of RET, VEGFR3 and PDGFRA, and can effectively treat diseases that are regulated and controlled by multi-target kinases and are related to abnormal signal transduction pathways of the multi-target kinases, including cancers of breast, respiratory tract, brain, reproductive organ, digestive tract, urinary tract, eye, liver, skin, head and/or neck and distant metastatic cancers thereof, and lymphoma, sarcoma, leukemia and the like. The active ingredients of the pharmaceutical composition of the present invention comprise a multi-target kinase inhibitor, which accounts for 1-50 wt % of the composition.

Abstract: A system and methods are provided for determining a vehicle action during a phantom projection attack, including processing a received image to identify a traffic object, and creating from the received image multiple processed images that are applied to respective neural network (NN) models. Latent representations of the multiple processed images from each of the NN models are then fed to a combiner model trained to determine whether the latent representations indicate a phantom projection attack, and, responsively to a determination of a phantom projection attack, issuing a phantom projection indicator.
