    摘要: The present invention is gallium nitride based operational amplifier because reliability and performance of the gallium nitride is better than the silicon counterpart in radiation environment. The operational amplifier includes four stages, first stage is dual input balanced output differential amplifier, second stage is dual input unbalanced differential amplifier, third stage is buffer stage to couple second and fourth stage, and fourth stage is cascaded common source amplifier with degeneration. A capacitor coupled between second and third stage is to enhance the stability of operational amplifier.

    摘要: The disclosure provides a method for evaluating whether an individual with cancer is suitable for being administered with anti-cancer drugs. Wherein the anti-cancer drug is a CDK inhibitor. The method includes the following steps: (1) detecting a copy number of a first gene and a copy number of a second gene from an in vitro sample of the individual with the cancer to obtain a copy number variation (CNV) of the first gene and a copy number variation (CNV) of the second gene; (2) calculating a copy number variation ratio (CNV ratio) between the copy number variation (CNV) of the first gene and the copy number variation (CNV) of the second gene, wherein the first gene encodes a cyclin and the second gene encodes a cyclin dependent kinase inhibitor (CDKN); and (3) determining whether the individual with the cancer is suitable for being administered with the CDK inhibitor according to the CNV ratio.

    摘要: A center of pressure (CoP) based control system includes a sensing device and an electronic device connected to the sensing device. The sensing device includes sensors each of which continuously measures force exerted thereon by a subject and generates a sense signal based on a result of the measurement. The electronic device is connected to the sensing device, and receives the sense signals from the respective sensors, generates CoP data associated with a CoP trajectory based on the sense signals, determines whether a turning point exists in the CoP trajectory, generates an indication signal based on a result of the determination, and generates a control signal based on a direction of one of displacements of the CoP.
