Abstract: A method for controlling an antenna of a mobile communication application system based on double quaternions in MEMS inertial navigation. The method comprises: introducing an antenna control quaternion based on a navigation attitude quaternion; in each interrupt cycle of a navigation computer, updating the two quaternions respectively using a carrier system measured by a gyroscope relative to a rotation vector of an ideal platform coordinate system; in each filter cycle, correcting the error of the navigation attitude quaternion respectively using a Kalman filter; according to the relationship between the attitudes determined by the two attitude quaternions, determining the angular speed in an antenna control instruction; and finally, driving a servo system to rotate at an antenna servo control angle converted by an antenna control quaternion attitude.

Abstract: The present invention relates to a method for treating a Helicobacter pylori (IP) infection and/or an associated disease in an individual, comprising administering to the individual a therapeutically effective amount of a pharmaceutical composition containing a short-chain fatty acid or a pharmaceutically acceptable salt thereof, alone or in combination with an anti-HP agent, and a pharmaceutically acceptable carrier, wherein the short-chain fatty acid has the formula: in which R1 and R2, independently, are C1-C8alkyl or H, R3 is aryl or heteroaryl, and n is 0, 1, 2, 3, 4, 5 or 6. The present invention also relates to a method for treatment of Helicobacter pylori (HP) infection or disease associated with HP infection by administering a therapeutically effective amount of an HDAC inhibitor or a pharmaceutically acceptable salt thereof, alone or in combination with an anti-HP agent, and a pharmaceutically acceptable carrier.

Abstract: A method for treating a subject having radiation fibrosis is disclosed comprising topically administrating to the subject an effective amount of a compound of the formula: R1 and R2, independently, is H or C1˜C6 alkyl; R3 is aryl or heteroaryl; and n is 0, 1, 2, 3, 4, 5, or 6.
