Abstract: Disclosed are a Nested Named Entity Recognition method based on part-of-speech awareness, system, device and storage medium therefor. The method uses a BiLSTM model to extract a feature of text word data in order to obtain a text word depth feature, and each text word of text to be recognized is initialized into a corresponding graph node, and a text heterogeneous graph of the text to be recognized is constructed according to a preset part-of-speech path, the text word data of the graph nodes is updated by an attention mechanism, and the features of all graph nodes of the text heterogeneous graph are extracted using the BiLSTM model, and a nested named entity recognition result is obtained after decoding and annotating. The present disclosure can recognize ordinary entities and nested entities accurately and effectively, and enhance the performance and advantages of the nested named entity recognition model.

Abstract: Disclosed is an improved approach for efficiently implementing a three-dimensional integrated circuit (3D-IC) design with heterogeneous and/or homogeneous dies. A first die design and a second die design in a three-dimensional (3D) electronic design maybe identified, and a wrapper design may be generated for at least a block of circuit component designs in the second die design for concurrent implementation of both the first and the second die designs. Both the first and the second dies of the 3D electronic design are concurrently implemented based at least upon a floorplan that is generated with at least the wrapper design for the 3D electronic design. A first wrapper and a second wrapper may be respectively generated for the first die design and the second die design based at least in part upon a result of the concurrent implementation.

Abstract: A wireless charger includes a base, a first transmitter, a driver circuit, a controller and an energy radiation member. The first transmitter coil is fixed in the base. The driver circuit is disposed in the base. The controller is disposed in the base and connected to the driver circuit. The energy radiation member is detachable from the base and connected to the base through a wire, and the energy radiation member comprises a second transmitter coil. In the case that the energy radiation member and the base are in a separated state, the driver circuit drives, under control of a control signal from the controller, the first transmitter coil and the second transmitter coil to operate.

Abstract: A minimally invasive hip joint and a joint replacing method are provided. The minimally invasive hip joint includes a threaded rod and a joint body including a plurality of elastic sheets, with their top ends being all disposed at a top end position of the threaded rod, and bottom ends being all movably sleeved on the threaded rod and dispersedly distributed along the circumferential direction of the threaded rod; and the threaded rod is threadedly engaged with a locking component located at the below position of the elastic sheets. The joint replacing method comprises replacing a damaged or undamaged femoral head on a femur with the aforementioned minimally invasive hip joint. When replacing a damaged or undamaged femoral head with the minimally invasive hip joint, it is only necessary to drill at the outer side of the trochanter major and rotate the locking component.
