    • Provided herein are urine progenitor cells and methods for producing a culture of urine progenitor cells from a urine sample. The cells may be selected based upon the use of a selective cell medium, based upon morphology, and/or by selecting cell-specific markers. Also provided is an isolated urine progenitor cell that is c-kit positive and can differentiate into urothelium, smooth muscle, endothelium or interstitial cells. Methods of use of urine progenitor cells are provided, wherein cell are seeded onto a tissue scaffold are provided. Methods of treating a subject in need thereof are also provided, including providing a bladder tissue substrate that includes differentiated UPCs and transplanting the substrate into the patient. Finally, kits are provided that include a container suitable for the transport of a urine sample; media; one or more antibiotics; a package for holding said container, media, and antibiotics; and optionally, instructions for use.

    • Provided is a flux regulation method for use in a power converter, wherein the method is carried out by a flux bias controller. The flux bias controller includes a current detector which is configured to detect the primary current of the transformer of the power converter in a predetermined switching cycle, a DC bias processor which is configured to obtain the duty ratio control signal according to the sampled primary current outputted from the current detector for a switching cycle later than the predetermined switching cycle, and a PWM controller which is configured to generate driving signals to control the on/off operations of the switching circuit of the power converter according to the duty ratio control signal, thereby suppressing the DC bias of the transformer by regulating the duty ratio of the switch circuit.
    • 提供了一种用于功率转换器的磁通调节方法,其中该方法由磁通偏压控制器执行。 通量偏置控制器包括电流检测器,其被配置为在预定的开关周期内检测功率转换器的变压器的初级电流; DC偏置处理器,被配置为根据所输出的采样的一次电流获得占空比控制信号 从电流检测器开始比预定开关周期晚的开关周期,以及PWM控制器,其被配置为产生驱动信号,以根据占空比控制信号来控制功率转换器的开关电路的接通/断开操作,由此 通过调节开关电路的占空比来抑制变压器的直流偏压。
