    摘要： A transceiver circuit having 10 mb and 100 mb transmit and receive circuitries using the power saving methods of the present invention is disclosed. The power consumption of the transceiver circuit can be significantly reduced by providing each defined subcircuit with its own power supply and means of activation and deactivation. However, the method for activating and deactivating digital subcircuits and analog subcircuits are different and therefore different types of control signals and methods are provided. Furthermore, there are two general types of power-saving situations. The first type is near total circuit power-down and the second type is partial circuit power-down. The present invention in yet another embodiment discloses a method for minimizing energy usage during idle period.

    摘要： A method for realizing an authentication center (AC) and an authentication system are disclosed. The method comprises: a UE sends an authentication request to an AC and applies for temporary authentication information, the AC assigns a first authentication random code to the UE, then the UE calculates a first response code and sends it to the AC, the AC assigns the temporary authentication information to the UE after authentication and authorization; the UE sends a login request to the application system (AS) which assigns a second authentication random code to the UE, and the UE uses it and the temporary authentication information to calculate a second response code, and sends this code to the AS; the AS sends the second response code to the AC for authentication and authorization; the AC returns the authentication result to the AS which in turn returns the authentication result to the UE.

    摘要： The present invention provides non-small cell lung cancer markers and the use thereof. The non-small cell lung cancer markers in the present invention include at least one of the 26 selected detectable mature microRNAs existing stably in human serum or plasma. The invention also provides a probe combination, kit and biochip for detecting the non-small cell lung cancer markers. The invention further provides a method for detecting microRNAs in the serum of lung cancer patients. By detecting the variations of microRNAs in the serum of lung cancer patients, the disease can be diagnosed in vitro; the progression course of the disease can be predicted; the occurrence of complications, the rate of relapse and the prognosis of the disease can be monitored; the drug efficacy and therapeutic effects can be analyzed. The method in the present invention enables extensive detection spectrum, high sensitivity, low cost, convenient sample taking and preservation. The method can be applied in the general survey of disease, solves problems of the low specificity and sensitivity encountered with previous single markers, and increases significantly the clinical detection rate of diseases, all of which make it an effective means for diagnosing diseases at an early stage.

    摘要： For rotationally symmetric aspheric lenses, one can establish lens design and layout based upon the phase delay function exp[−iφ(ρ)]. An embodiment of the invention is a method for calculating a corresponding variation in focal length denoted by f(ρ). According to an aspect, one can also assert a shape for the focal length f(ρ) and thereafter calculate a phase delay function in order to synthesize a novel lens. New EDoF lens designs are obtained by selection of an inner and outer focal length connected by a simple curve that can be approximate by a polynomial. From the selected f(ρ), one can synthesize a finished EDoF lens design and fabricate the lens. Another aspect of this invention is directed to a method to tailor prior-art EDoF lenses so that their performance over some range is improved.
