Abstract: A method for predicting mtDNA mutation threshold, fertility risk and oocyte retrieval number includes: establishing an incidence probability prediction model of mitochondrial mutation and estimating a mutation threshold s; establishing a fertility risk prediction model and predicting a fertility risk of a mutation carrier; and establishing an oocyte retrieval prediction model by binomial distribution and calculating oocyte retrieval number by PGT of a mutation carrier. The incidence probability prediction model is used to estimate a threshold value of common mtDNA mutations and predict a mother's fertility risk and the oocyte retrieval number by PGT. On the basis of the fertility risk prediction model and oocyte retrieval prediction model, the fertility risk and a minimum oocyte retrieval number by PGT needed to give birth to a healthy offspring can be calculated by knowing a mitochondrial DNA mutation ratio of mutation carrier which is helpful for genetic management and genetic consultation.

Abstract: In the field of communications technologies, embodiments of the present invention provide a method for detection using a YI algorithm and a YI detector, so as to solve the technical problem of poor detection performance caused by signal environment variation in the prior art. In the embodiment of the present invention, parameters are obtained according to a received signal; a level threshold at each level starting from a level corresponding to a Tailbits value is obtained according to the parameters, and validity of at least one node at the level is determined according to the level threshold, where the level is the same as a level of the level threshold; and a detection identifier is output according to the validity. The embodiment of the present invention is mainly applied to a scenario of detection using thresholds.

Abstract: An electronic device includes a front frame, a back cover, a support stand rotatably connected to the back cover, a display panel and a circuit board. The display panel and the circuit board are fixed between the front frame and the back cover. The circuit board includes a first contact and a number of second contacts. The second contacts surround the first contact. The support includes a central shaft and a third contact. The central shaft is electrically connected to the first contact. The third contact rotates with the rotation of the central shaft to contact each of the second contacts. The circuit board includes a circuit and a processor. The electric circuit generates different signals when the first contact is connected different second contacts. The processor adjusts an orientation of display content on the display panel to rotate based on the signal.
