Publication number: 20220304313Abstract: 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.Type: ApplicationFiled: March 22, 2022Publication date: September 29, 2022Inventors: Lianhui ZHANG, Huishan WANG, Lisheng LIAO, Wenting WU, Lingling DONG, Xinghui FAN

Patent number: 10139948Abstract: 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.Type: GrantFiled: August 24, 2016Date of Patent: November 27, 2018Assignees: BOE TECHNOLOGY GROUP CO., LTD., BOE (HEBEI) MOBILE DISPLAY TECHNOLOGY CO. LTD.Inventors: Mingyan Zhu, Xiangyuan Sheng, Weihou Li, Lingling Dong, Yu Chen

Patent number: 9384708Abstract: The present document provides a method and apparatus for managing a display screen, and the display screen includes at least two display areas. The method includes: detecting a first display effect damaged value of a first display area in the at least two display areas; comparing the first display effect damaged value with a predetermined threshold value, and outputting a first comparison result; and when the first display effect damaged value is larger than the threshold value, adjusting a display effect of the first display area to a first display effect based on the first display effect damaged value, to match the first display effect with a second display effect of a second display area without stains. Through the above technical scheme, adjustment is performed on display effect of the display screen, which guarantees the display effect of the display screen and makes the user experience of users enhance greatly.Type: GrantFiled: November 4, 2011Date of Patent: July 5, 2016Assignee: ZTE CorporationInventors: Fengpeng Liu, Haibo She, Dongmei Liu, Lingling Dong, Qinli Sun, Zongwei Huang
