Abstract: Example aspects include techniques for query processing over deep neural network runtimes. These techniques include receiving a query including a query operator and a trainable user defined function (UDF). In addition, the techniques include determining a query representation based on the query, and determining, for performing the query in a neural network runtime, an initial neural network program based on the query representation, the initial neural network program including a differentiable operators corresponding to the query operator. and executing the neural network program in the neural network runtime over the neural network data structure to generate a query result. Further, the techniques include training the initial neural network program via the neural network runtime to determine a trained neural network program, and executing the trained neural network program in the neural network runtime to generate inference information.

Abstract: The present disclosure provides a heteropoly oligosaccharide and an application thereof in improving plant disease resistance. The heteropoly oligosaccharide includes seven D-glucose residues and one D-galactose residue.

Abstract: A method for preventing information from being stolen includes: pre-establishing a sensitive character database in a mobile terminal; monitoring screen recording content when a screen recording function is activated by the mobile terminal; determining whether a sensitive character in the sensitive character database appears in the screen recording content; and if yes, the screen recording function is paused or a screen recording result is displayed by a black screen. A storage device and a mobile terminal are also provided.
