摘要： In an ultra-wideband (UWB) band-pass filter, an equivalent circuit of a band-pass filter for direct frequency conversion is configured to have a series LC resonator and a parallel LC resonator, the parallel LC resonator is implemented as a short stub and an open stub, and the series LC resonator is implemented by modeling an inductor and a capacitor as a distributed constant circuit. The series LC resonator is implemented to have a 3D structure for effective designing of the band-pass filter by a new method of implementing a series resonator circuit. In the UWB band-pass filter, a low-pass filter for improving band-stop characteristics is additionally connected.

摘要： The present invention provides a method for producing cloned cows by employing in vitro maturation of oocytes and nuclear transfer techniques. The method comprises collecting donor somatic cell lines from cows; maturing oocytes extracted from an ovary in vitro; enucleating the oocyte by cutting a portion of the zona pellucida and squeezing out a portion of the cytoplasm, including the first polar body; inserting the donor somatic cell into the oocyte; electrofusing the cells to produce embryos; post-activating the embryos; transferring them into surrogate cows to produce cloned calves.
