    摘要： A method and system for extracting coronary vessels fluoroscopic image sequences using coronary digital subtraction angiography (DSA) are disclosed. A set of mask images of a coronary region is received, and a sequence of contrast images for the coronary region is received. For each contrast image, vessel regions are detected in the contrast image using learning-based vessel segment detection and a background region of the contrast image is determined based on the detected vessel regions. Background motion is estimated between one of the mask images and the background region of the contrast image, and the mask image is warped based on the estimated background motion to generate an estimated background layer. The estimated background layer is subtracted from the contrast image to extract a coronary vessel layer for the contrast image.

    摘要： For cognitive radio systems, the transmit power of a cognitive radio device is controlled so that the cognitive, unlicensed radio device does not interfere with the use of a shared spectrum by a primary, licensed device. Controlling the transmit power includes determining a distance, or a function of the distance, between a primary transmitter of the primary device and the cognitive radio device based on sensing information from a spectrum sensing process. The maximum transmit power of the cognitive radio device is then dynamically controlled based on the distance, or the function of the distance, while considering a worst case scenario of an underlying cognitive radio model, to guarantee a quality of service requirement of the primary device.

    摘要： The present invention relates generally to organic chemistry, biochemistry, pharmacology and medicine. More particularly, it relates to 3-benzylidene-indolin-2-one derivatives and their physiologically acceptable salts and prodrugs which modulate the activity of protein kinases (“PKs”), especially protein tyrosine kinase, and, therefore, are expected to exhibit a salutary effect against disorders related to abnormal PK activity. The present invention is further directed to methods of using of these compounds, alone or in combination with other therapeutic agents, for the alleviation, prevention and/or treatment of protein kinase-mediated diseases and disorders, such as cancer.

    摘要： The linear vibrator includes a base forming a hollow space, a suspension fixed on the base, and an oscillating portion suspended in the hollow space by the suspension. The suspension defines a flat part, a connecting portion bent downward from the flat part, and a spring portion extended horizontally in a direction parallel to flat part from the end of the connecting portion. The suspension is directly connected with the outside component, thereby transmitting the vibration to the outside component rapidly.

    摘要： A control circuit for a switched mode power supply includes a transconductance amplifier circuit for receiving a voltage signal related to a current from an input of the power supply and producing a first signal, an analog signal processor coupled to the amplifier circuit for receiving the first signal and a second signal from the input of the power supply and a third signal from an output of the power supply. The analog signal processor is configured to produce a fourth signal as a function of the first, the second, and the third signals. An adder circuit is coupled to the fourth signal and a dimmer control signal, and the adder circuit is configured to output a fifth signal. A comparator circuit is coupled to the adder circuit for providing a control signal to a power transistor that controls current flow in the power supply based on comparison of the fifth signal and a reference signal.
