Abstract: The present disclosure belongs to the technical field of biological control and prevention, and it was found that Pseudomonasnitroreducens strain HS-18 has good degradation activity on AHLs with C4-C14 chain length, with an efficient and notable degradation effect, providing a new biocontrol agent for prevention and treatment of AHLs-mediated pathogens provides and broadening the quorum quenching species of AHL signaling molecules. By using molecular biology technologies, AHL-quenching genes for HS-18, i.e., the encoding genes aigA and aigC of N-acyl homoserine lactone acyl transferase are cloned. The genes aigA and aigC have broad-spectrum and efficient quenching activities on AHLs with different side chain lengths and different side chain substituents. The expression of aigA and aicC can significantly weaken the motility of AHL-mediated pathogens, the formation of biofilm and the production of virulence factors and significantly weaken the pathogenicity of pathogens to the host plant.

Abstract: The present disclosure provides a touch detection circuit, its driving method and a display device. The touch detection circuit includes a touch sensing electrode, a switch control unit, a touch detection unit, a first control signal terminal, a second control signal terminal, a third control signal terminal, a fourth control signal terminal, and a signal output terminal. At a charging stage subsequent to an initialization stage, a touch capacitance is generated at a position corresponding to the touch sensing electrode in the case that the touch sensing electrode is being touched, and the touch sensing electrode is charged through the switch control unit under the control of the first control signal terminal. As a result, it is able to detect charges stored on the touch sensing electrode by the touch detection unit at a detection stage, thereby to determine whether or not the touch sensing electrode is being touched in accordance with a detection signal from the signal output terminal.

Abstract: A serial bus network includes a voltage regulator, a plurality of power switches, and a voltage monitor. The voltage regulator provides power to a plurality of serial buses. Each of the serial buses provides power from the voltage regulator to a device coupled to the serial bus. Each of the power switches switches power from the voltage regulator to one of the serial buses, and includes an input terminal coupled to a voltage regulator output, and an output terminal coupled to one of the serial buses. The voltage monitor is coupled to the voltage regulator and to the output terminal of each of the power switches. The voltage monitor compares bus voltages at the output terminals of the power switches, identifies a lowest of the bus voltages, and adjusts the voltage regulator output voltage such that the identified lowest of the bus voltages is within a predetermined operational voltage range.
