A method for correcting a determination threshold of a floor medium and a method of detecting thereof are provided. The method is used for controlling a mobile robot equipped with a sound emitter and a sound receiver to detect and recognize the floor medium during a movement just started. A first detection result of a current floor medium is obtained by actively transmitting and receiving a sound signal, then, a to-be-adjusted detection result of the current floor medium is obtained only by passively receiving the sound signal through the sound receiver, and according to the similarity/difference of the two detection results, the determination threshold is corrected in the case of passively receiving the sound signal, so that the to-be-adjusted detection result is determined to be consistent with the first detection result.

The present invention identifies the PPP2R1B gene, as a human tumor suppressor gene. Sequencing of the PPP2R1B revealed that the gene is located on human chromosome 11q22-24 and that gene were mutated in tumors and tumor cell lines, leading to the classification of this gene as a tumor suppressor. Further analyses have demonstrated the presence of a number of mutations in the gene in lung, colon, breast and cervical cancer cells. Methods for diagnosing and treating cancers related to this tumor suppressor also are disclosed.
