Abstract: A method for assessing test adequacy of deep neural networks based on element decomposition is provided. The network testing is divided into black box testing and white box testing, of which key elements are decomposed and defined. Network parameters including a weight matrix and a bias vector are extracted. Importance values of neurons in individual layers of the deep neural network are calculated and clustered, and an importance value hot map of neurons in each layer is generated based on clustering results. Mutation testing, and index calculation and evaluation are performed.

Abstract: The present application discloses a PEGylated asparaginase and use thereof. In this application, the polyethylene glycol (PEG) is coupled to the N-terminal amino of 1 or 2 subunits of L-asparaginase, and the molecular weight of the PEG is 30-40 KDa. The PEG is preferably branched and has an aldehyde serving as an activating group. The PEGylated asparaginase is useful in the preparation of anti-tumor drugs.

Abstract: The disclosure provides a method of making an iron matrix composite. A Fe—Ni—P composite powder having a particle size of one to two micrometers and a Fe—N powder having a particle size of 100 to 250 nanometers are used as the raw material. The size and axial displacement of pressing heads of a graphite mold are controlled to realize the control of the porosity of porous iron. The composite produced comprises two surface layers of a Fe—Ni—P alloy and an intermediate layer of porous iron having a porosity of 14 to 39%. The method enables a reduced weight of the Fe—Ni—P alloy and enables shock absorption and damping properties to be imparted to the composite. In addition, an optional subsequent deep cryogenic treatment allows the Fe—Ni—P alloy to be subjected to phase transition from a metastable gamma-phase to an alpha-phase, thereby substantially improving the hardness and strength thereof.
