Abstract: Disclosed in the present invention is a generative event extraction method based on ontology guidance, including: (1) constructing an event ontology knowledge base; (2) designing an event trigger word extraction template and an event argument extraction template; mapping an input event text to a first input sequence, and mapping an input event text integrating an event ontology to a second input sequence; (3) designing a class label mapping function that maps multi-word labels to event types and/or role types; (4) extracting the event ontology corresponding to the input event from the event ontology knowledge base, and constructing the first input sequence and the second input sequence according to the event trigger word extraction template and the event argument extraction template; and (5) predicting, by the event extraction model, the event type and the role type according to the class label mapping function and a processing mechanism thereof, and outputting an event trigger word span and an event argument

Abstract: A continuously variable transmission with both equal-difference output and equal-ratio output includes an input mechanism, a hydraulic transmission mechanism, a planetary-gear-set convergence mechanism, an equal-difference output mechanism, an equal-ratio output mechanism, a clutch assembly, and a brake. The clutch assembly connects an output end of the input mechanism to an input end of the hydraulic transmission mechanism and the planetary-gear-set convergence mechanism and connects an output end of the hydraulic transmission mechanism to the planetary-gear-set convergence mechanism. The clutch assembly connects the planetary-gear-set convergence mechanism to the equal-difference output mechanism and the equal-ratio output mechanism. The clutch assembly connects the equal-ratio output mechanism to the equal-difference output mechanism.

Abstract: A heparin skeleton synthase originates from Neisseria animaloris, with an amino acid sequence as shown in SEQ ID NO.2 and a nucleotide sequence of the coding gene as shown in SEQ ID NO.1. Its recombinant expression level is 6.8 times that of the existing heparin skeleton synthase KfiA from Escherichia coli K5, and total enzyme activity per fermentation liquor is 5.22 times that of the heparin skeleton synthase KfiA. The heparin skeleton synthase mutants obtained through site-directed mutagenesis of the sites No. 16, No. 25, No. 30, No. 111, No. 165, and No. 172 in the amino acid sequence of the said heparin skeleton synthase all have high expression levels.

Abstract: A battery case and a battery are provided. The battery case includes a case body. The case body is formed by a sheet-shaped plate being bent and welded. The plate has a first end and a second end. After the case body is bent, the first end is welded to the second end, a welding position at which the first end is welded to the second end is compressed to form an explosion-proof recess.

Abstract: A network security management method is provided. In the method, configuration data that includes at least one access control policy for a network asset of a target cloud tenant is received. The network asset includes a private network, a subnet of the private network, and a cloud instance of the subnet. A network management and control unit and an access control policy set corresponding to the network management and control unit are determined according to the configuration data. The network management and control unit includes one or more of a private network-level management and control unit, a subnet-level management and control unit, and an instance-level management and control unit. The access control policy set of the network management and control unit is transmitted to the cloud instance that is associated with the network management and control unit to manage network traffic of the cloud instance.

Abstract: An access processing method and apparatus for remotely controlling a terminal, and a storage medium. The method includes: obtaining identity information of a target user from a user terminal, returning a controllable device set corresponding to the target user to the user terminal based on the identity information, receiving, from the user terminal, a target device identifier selected from the controllable device set, and obtaining verification information of a target device indicated by the target device identifier, the verification information including: access information for accessing the target device, and controlling the verification information to be transmitted to the target device to allow, based on verification of the verification information passing, access and remote control on the target device.

Abstract: The invention relates to antibacterial compounds and their use to treat bacterial infections. More particularly, the invention relates to substituted biphenyl compounds having antibacterial activity. The invention provides methods for treating bacterial infections using PBDEs that have not previously been used to treat bacterial infections. The invention further provides novel PBDEs that are useful in such methods.
