Abstract: A low-cost and high-strength Bi-based superconducting wire/tape and a preparation method thereof, the preparation method includes: 1. subjecting a first Bi-based superconducting wire/tape to electrochemical silver reduction to remove a Ag alloy layer to obtain a second Bi-based superconducting wire/tape; and 2. subjecting the second Bi-based superconducting wire/tape to surface enhancement, such that a Cu layer is formed to obtain the low-cost and high-strength Bi-based superconducting wire/tape. An electrochemical silver reduction technology combines with an electrochemical additive method to remove a Ag alloy layer on a surface of a Bi-based superconducting wire/tape and coat a high-strength Cu layer, such that a low-cost and high-strength Bi-based superconducting wire/tape can be prepared, which reduces a preparation cost and improves a strength of a Bi-based superconducting wire/tape to meet the application requirements of large super-strong magnets.

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.

Abstract: A high-temperature wide-bandgap power module and a preparation method thereof is provided in the present application. In the high-temperature wide-bandgap power module, SiC power chips are arranged in the cavity, and bonding wires are used to establish electrical connections. An ultrathin composite conformal coating consists of inorganic film and Parylene-HT film is arranged on the surface of the circuit to provide long-term reliable insulation while only imposing minor thermo-mechanical stresses on bonding joint at high-temperatures, which prolongs the module's life time. In addition, the hermetic sealing adopted in the present application blocks the external water, oxygen and chemical pollution, thereby alleviating the thermal degradation of the conformal coating and safeguards the internal circuit. Overall, the hermetic sealing and conformal coating ensure the long-term 250 degrees high-temperature working capability of the wide-bandgap power module.

Abstract: A data-driven audio codec system that involves producing multiple compressed streams comprising encoded information (e.g., codeword indices) at different time scales (time intervals or frequency). This may allow for separation of different properties of speech, such as content and aspects of style (prosody), into the different compressed streams without explicitly enforcing it, i.e., in an unsupervised manner. Speech audio is encoded to produce a plurality of encoded streams comprising encoded information for the speech audio at different time scales. The plurality of encoded streams are decoded to generate output audio.
