Abstract: Methods, systems and apparatus, including computer programs encoded on computer storage medium, for training a neurosymbolic data imputation system on training data inputs in a domain to impute missing data in a data input from the data domain. In one aspect a method includes, for each training data input, adding random noise to missing fields of the training data input; generating an embedding data input for the training data input using concept embeddings from the domain; processing the noisy data input and the embedding data input through a correlation network to obtain correlation data; applying attention to the noisy training data input and the correlation data to generate a combined data input; processing, by an autoencoder, the combined data input to obtain a decoded data output; computing a difference between the decoded data output and the training data input; and updating parameters of the data imputation system using the difference.

Abstract: A device may generate a synthetic knowledge graph based on a true knowledge graph, may partition the synthetic knowledge graph into a set of synthetic data partitions, and may determine, using a plurality of teacher models, an aggregated prediction. The aggregated prediction may be based on individual predictions from corresponding individual teacher models included in the plurality of teacher models. The device may determine, using a student model and based on the synthetic knowledge graph and noise, a student prediction. The student model may be trained based on historical synthetic knowledge graphs and historical aggregated predictions associated with the plurality of teacher models. The device may determine an error metric based on the aggregated prediction and the student prediction, and may perform an action associated with the synthetic knowledge graph based on the error metric.

Abstract: A device processes a knowledge graph to select a set of triples and generates a first class based on the set of triples. The device determines a quantity of quasi-identifier attributes in the first class and compares the quantity to a predefined parameter. The device embeds the knowledge graph to generate an embedding space representation, identifies a second class, and determines a first quantity of nodes in the first class and the second class. The device compares the first quantity to the predefined parameter and identifies a third class. The device determines a second quantity of nodes in the first class and the third class and compares the second quantity to the predefined parameter. The device merges the second class or the third class with the first class, based on the comparisons, to generate anonymized nodes for the knowledge graph.

Abstract: The present invention provides a use of IGF-1 in the preparation of medicaments for preventing and/or treating liver tumors, relating to the technological field of prevention and treatment of hepatocarcinoma. In embodiments of the present invention, experiments are carried out on mice, demonstrating that over-expression of IGF-1 in hepatocytes induces the apoptosis of cancerous cells indirectly, and inhibits the occurrence and development of liver tumors; high level of IGF-1 significantly promotes the function of thymus, delays the degeneration of thymus, and does not cause the dysfunction of thymus; high level of IGF-1 significantly promotes the function of spleen T lymphocyte; high level of IGF-1 significantly enhances the number and activity of tumor infiltrating T lymphocytes; long-term over-expression of IGF-1 does not significantly promote the incidence of tumors in all organs and tissues in mice, indicating the safety of high IGF-1 level in the body.

Abstract: A mold with cavities for nanoimprint lithography and a method of imprinting the same. The mold is a one-piece structure, including an upper mold and a lower mold which are welded together. The upper mold is evenly provided with a plurality of stepped holes. A plurality of grooves are provided at an upper surface of the lower mold. Both ends of each groove are respectively connected to an external high-pressure water pump and an external vacuum pump via pipelines. An airtight cavity is additionally provided at the interior of the mold to form a negative pressure in the cavity by vacuumizing during the imprint process. In the demolding, a crack is formed at the interface between the mold and the imprint resist by using water pressure and expands to the entire interface for the demolding of the imprinted structure.

Abstract: A method and apparatus for integration of operating systems solve the problem in the conventional techniques with low efficiency in switching among the operating systems. The techniques of the present disclosure firstly starts a first operating system and its agent process, and then starts a second operating system, wherein the second operating system may call the agent process to request the first operating system for resources required by the second operating system. The second operating system may directly request the first operating system for the needed resources, which realizes the coexistence of the first operating system and the second operating system without mutual switching between the operating systems.
