Abstract: A viral vector delivery system for both respiratory and digestive tracts of pigs and an application thereof are provided. The viral vector delivery system includes a backbone plasmid and a helper plasmid. The backbone plasmid is produced by inserting a full-length cDNA of porcine enterovirus B (PEVB) into a pUC57 plasmid. The helper plasmid is produced by inserting a green fluorescent protein-coding gene into a plasmid pCAG-T7-polymerase. The viral vector delivery system can be constructed with high efficiency, can quickly cause a cytopathic effect (CPE) after infecting cells, has a viral titer up to 107.75 TCID50/mL, and can maintain high stability. A pathogenic epitope for the respiratory and digestive tracts of pigs is inserted into the backbone plasmid to produce a vaccine antigen, which is non-pathogenic, has high stability and a high viral titer, and allows a prominent immunization effect after being inoculated in pigs.

The terminal structure includes a phosphorus-doped silicon oxide layer, a silicon nitride layer, a silicon-rich silicon nitride semi-insulating layer, an undoped silicon dioxide layer, and an organic medium layer. The silicon-rich silicon nitride semi-insulating layer is of an alternating superposition structure of a silicon-rich silicon nitride layer and an ultra-thin silicon nitride barrier layer. The terminal structure effectively prevents external moisture from invading the power device, which improves the robustness of the power device under a moisture condition. The multi-layer silicon-rich silicon nitride is used as a semi-insulating layer, which makes an electric field on a surface of the power device evenly distributed in gradient, prevents the electric field from being gathered at a device terminal.

Abstract: A detection method of polyamines is used to solve the problem that the conventional method is not suitable for detecting polyamines. The detection method of polyamines includes providing a sample with polyamines. The sample and a derivatization reagent with an isothiocyanate group are dissolved in a working solution to form a mixture, while a thiocarbamoylation reaction between the polyamine in the sample and the derivatization reagent is performed to obtain a derivatization solution with a thiourea derivative. The thiourea derivative in the derivatization solution is then detected to obtain a value of polyamine. With such performance, polyamine in the sample can be effectively detected. A diagnostic method of cancers is also disclosed.

Abstract: A device is configured to detect multiple different wakewords. A device may operate a joint encoder that operates on audio data to determine encoded audio data. The device may operate multiple different decoders which process the encoded audio data to determine if a wakeword is detected. Each decoder may correspond to a different wakeword. The decoders may use fewer computing resources than the joint encoder, allowing for the device to more easily perform multiple wakeword processing. Enabling/disabling wakeword(s) may involve the reconfiguring of a wakeword detector to add/remove data for respective decoder(s). Specific decoders may be activated/deactivated depending on device context, thereby efficiently managing device resources.
