Abstract: A high viscosity acrylic adhesive is provided, which is composed of acrylic resin polymer as a raw material, mixed with a defoaming agent, an anti-aging agent, etc. By preparing a cross-linked modified monomer containing multiple unsaturated vinyl substituents for acrylic resin polymer, a cross-linked network-like structure of acrylic resin polymer can be obtained. The cross-linked structure of acrylic resin polymer has higher internal stress and can exhibit better bonding performance. The cross-linked modified monomer structure contains many ether bonds generated by cycloaddition reaction, which can form hydrogen bonds with a substrate to enhance the bonding performance of the adhesive. The increase in crosslinking density can hinder the movement of the molecular chains of acrylic resin itself, and the rigid benzene ring structure and high bond energy silicon oxygen bonds in the crosslinked modified monomer structure can synergistically enhance the high-temperature resistance of the adhesive.

Abstract: Provided are an EPSPS enzyme mutant, a nucleic acid molecule, an expression cassette, an expression vector, a recombinant bacterium or a recombinant cell and use thereof. The EPSPS enzyme mutant can effectively solve the problem of non-selectable damage to crops caused by herbicides such as glyphosate, and provides a new route for cultivating glyphosate-resistant crop varieties. Moreover, the EPSPS enzyme mutant also has relatively high practicability and promotional value, can improve a weed control effect, reduce weeding costs, and elevate crop yields in agricultural production. Besides, it further provides an expression cassette expressing the EPSPS enzyme mutant, where the expression cassette contains an EPSPS mutant gene conferring glyphosate resistance on a variety of plants such as soybean and rice.

Abstract: Provided is a biochar-anaerobic membrane biological treatment system and process. The system mainly includes a reaction tank, a membrane module, a macroporous gas distribution device, low-temperature pyrolysis biochar. The application of the process to sewage treatment shows that: under the conditions that the hydraulic retention time is 3.2-7.2 h, the membrane flux is 12.0-17.8 L/m2/h, and the sludge concentration of 7.2-15.6 g/L, multiple objectives of promoting organic micropollutants (OMPs) biotransformation, accelerating methane production and strengthening membrane fouling control were achieved. The system improved OMPs removal efficiency by more than 20%, decreased membrane fouling rate by 50%, and reaching an organic matter removal efficiency of more than 86% at low temperature. The system and process solve the problems of poor OMPs removal efficiency, serious membrane fouling, and low methane yield at low temperature in the anaerobic membrane biological treatment system.

Abstract: Methods, apparatuses, and systems are described for determining whether a user device connected to a network via a first communication channel in a first band of a network device should connect to a second communication channel in a second band of the network device. The network device may determine a trigger event based on a characteristic of the first communication channel. Based on the trigger event, the network device may compare one or more characteristics of the first communication channel with one or more thresholds to determine whether the user device should connect to the second communication channel in the second band.

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.

Abstract: An approach of the present disclosure includes an algorithm to encode an instruction set of a domain-specific processor automatically in an optimal way, and which yields area-effective hardware. Instruction operands and opcodes can be encoded separately or at the same time. Instructions are not encoded one by one but can be encoded in groups, and instructions are grouped automatically. The decoding logic of control signals for each group of instructions, such as register read enable and write enable, is fed to a logic minimizer to obtain an encoding constraint matrix, and the encoding of each instruction in each instruction group is done using an optimal state assignment method.

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.
