Publication number: 20220411810Abstract: The present invention discloses a method for site-directed modification of whole plant through gene transient expression. The method as provided for conducting site-directed modification to a target fragment of a target gene in a whole plant comprises the following steps: transiently expressing a sequence-specific nuclease in said plant, wherein a whole plant is used as the subject for transient expression, said sequence-specific nuclease targets and cleaves said target fragment, thereby the site-directed modification is achieved via the self DNA repairing of said plant.Type: ApplicationFiled: August 19, 2022Publication date: December 29, 2022Applicant: INSTITUTE OF GENETICS AND DEVELOPMENTAL BIOLOGY, CHINESE ACADEMY OF SCIENCESInventors: Caixia GAO, Yi ZHANG, Zhongyi WU, Kang ZHANG

Patent number: 10930031Abstract: A method for synchronizing list-mode data of single events in a PET imaging includes: acquiring list-mode data of single events of each independent detector module, calculating a probability density of time intervals between occurrences of single events in detector module and setting initial parameters, determining detection starting time difference of each detector module with iterative peak searching and graded time window, and performing synchronization correction and coincidence discrimination on the single event data in each detector module based on the detection starting time difference. A system for synchronizing list-mode data of single events in a PET imaging includes: a data acquisition and frequency difference compensation module, an initial parameter setting module, a coarse time scale coincidence module, a fine time scale coincidence module and a data synchronization correction and coincidence discrimination module.Type: GrantFiled: August 14, 2012Date of Patent: February 23, 2021Assignee: RAYCAN TECHNOLOGY CO., LTD.
