Abstract: This disclosure describes a system and method for compiling and executing machine learning inferences in an array of multi-core computing devices. Each multi-core computing device can be an application specific integrated circuit (ASIC) or group of ASICS. In many applications, the array of computing devices changes from inference to inference, and can be adjusted based on the requirements of the inference. Additionally, each ASIC can have multiple processing cores, and multiple types of processing cores. Therefore, performing optimizations and scheduling at compile time, can dramatically increase the efficiency of the array in executing the inference. In some implementations, it is possible to select an amount of time or effort to be spent optimizing during compiling, giving the user flexibility in determining whether to spend time during compilation or during execution.

Abstract: An IGBT physical model parameter extraction method includes obtaining an initial value and a transformation range of an IGBT physical model parameter; and correcting a model parameter by means of a correspondence between IGBT dynamic and static features and the IGBT physical model parameter and in combination with an experiment measurement result of the IGBT physical model parameter.

Abstract: Use of Cistanche deserticola polysaccharide (CDP) in promoting the proliferation and differentiation of female germline stem cells (FGSCs) is provided. Specifically, the addition of CDP in an in vitro cultivation system can promote the proliferation and differentiation of FGSCs, and especially can enhance the in vitro directed differentiation of FGSCs into oocytes, which provides a new research reference for studying the generation of oocytes in vivo and in vitro and also brings a new hope for research on physiological infertility.
