Publication number: 20240132979Abstract: A set of primers and probes for simultaneous detection of Cymbidium mosaic virus (CymMV), Odontoglossum ringspot virus (ORSV), and Cymbidium ringspot virus (CymRSV) and a method for detecting CymMV, ORSV, and CymRSV, along with a method for their detection, are disclosed. The method involves designing multiplex real-time quantitative PCR detection primers and probes for CymMV, ORSV, and CymRSV and applying these primers and probes to the real-time quantitative PCR simultaneous detection of CymMV, ORSV, and CymRSV. It allows for faster detection of CymMV, ORSV, and CymRSV, taking only one-third of the time compared to uniplex real-time quantitative PCR technology, thereby reducing testing costs by approximately ? to ½ for each sample. The primers and probes are highly specific and sensitive, with a sensitivity as low as 1 to 10 copies. It provides an efficient and feasible detection method for early detection and prevention of CymMV, ORSV, and CymRSV.Type: ApplicationFiled: January 1, 2024Publication date: April 25, 2024Applicants: FLOWER RESEARCH INSTITUTE OF YUNNAN ACADEMY OF AGRICULTURAL SCIENCES, YUNNAN UNIVERSITYInventors: Lihua Wang, Aiqing Sun, Xuewei Wu, Suping Qu, Yiping Zhang, Xiumei Yang, Yan Su, Feng Xu, Lifang Zhang

Patent number: 9813926Abstract: Provided are methods, corresponding apparatuses, and computer program products for performing out-of-band sensing on an unlicensed frequency band. A method comprises sending a configuration message for configuring measurement on at least one channel in a frequency band of a primary system; receiving a measurement report made based upon the configuration message; and determining the usability of the at least one channel based upon the measurement report, wherein the configuration message includes information regarding a respective predetermined threshold of energy detection or primary-system-feature detection, and the measurement report is for reception when a measured energy detection value or a measured primary-system-feature detection value of a received signal on the at least one channel is less than the respective predetermined threshold. With the claimed inventions, the spectrum efficiency would be improved and interference between a secondary system and an LTE system could be alleviated.Type: GrantFiled: March 26, 2012Date of Patent: November 7, 2017Assignee: Nokia Technologies OyInventors: Haitao Li, Haipeng Lei, Kodo Shu, Rui Wang, Honglin Hu, Huiyue Yi, Xiumei Yang
