The organic electroluminescent material is a metal complex comprising a ligand La having a structure of Formula 1 and a ligand Lb having a structure of Formula 2. When applied to electroluminescent devices, these new metal complexes can obtain more saturated green light emission and a lower efficiency roll-off, providing more options for the application of phosphorescent OLED materials and devices in high-brightness scenarios. Meanwhile, the metal complexes have lower device capacitance in the devices and better facilitate an increase in the response rate of OLED display devices at a low grayscale and an increase in the refresh rate of the devices. The metal complexes have great advantages and a broad prospect in industrial applications. Further provided are an organic electroluminescent device comprising the metal complex and a composition comprising the metal complex.

Abstract: Methods, systems, and devices for validity mapping techniques are described. A memory device may use a change log to update a mapping that indicates whether data stored at respective physical addresses is valid. For example, the memory device may receive a command associated with data having a corresponding set of addresses (whether logical block addresses or physical addresses). The memory device may set an entry of the change log based on whether the set of addresses are consecutive. For example, the memory device may identify whether the set of addresses are consecutive and may set a flag in the entry of the change log to indicate whether the addresses are consecutive. Then, the memory device may update one or more entries of the mapping corresponding to the entry of the change log to indicate whether the addresses corresponding to the one or more entries of the mapping store valid data.

Abstract: Provisioning an orchestration platform is provided. A pre-application programming interface (API) server hook is used to preprocess a request to generate a custom resource in the orchestration platform. The pre-API server hook generates a custom resource definition corresponding to the custom resource and generates the custom resource based on the custom resource definition. A custom resource definition generation event is monitored for, using a custom resource definition (CRD) meta-controller, to manage a custom resource definition controller corresponding to the custom resource definition. The CRD meta-controller retrieves the custom resource definition controller from a CRD controller configuration repository to deploy the custom resource definition controller on a worker node in the orchestration platform.
