Disclosed herein is a compound comprisingor a pharmaceutically acceptable salt or a prodrug thereof;wherein Y, A, X, R and D are as described. An opening of the battery case 5 is sealed with a sealing plate 10. A gas bubbling means is provided in the reaction chamber for bubbling the gas to be treated into the liquid thereby dissolving the gas into the liquid and increasing a pressure inside the reaction chamber. To minimize potential call failures during CSFB, the UE may autonomously perform an additional cell search, in particular a search for cells on a RAT different from the initial target RAT. Thus, the one or more circuits may be configured to mark instructions fetched into the processor’s instruction pipeline to indicate their branch prediction dependencies, directly or indirectly detect incorrect branch predictions, and directly or indirectly flush instructions in the instruction pipeline that are marked as being dependent on an incorrect branch prediction. Through the phonetic input method, the invention enables a user to select a candidate sentence that she wants to input, reducing the input error rate and increasing hisher input speed.
