OsUgp2, a rice UDP-glucose pyrophosphorylase gene, has previously been shown to preferentially express in maturing pollens and plays an important role in pollen starch accumulation. Here, a 1943 bp promoter fragment (P1943) of OsUgp2 was characterized by 5′ deletion and gain-of-function experiments. P1943 and its 5′ deletion derivatives (P1495, P1005, P665(More)
The objective of this study is to compare the accuracy of tumor grade in endometrial cancer between fractional dilatation and curettage (D&C) and postoperative hysterectomy specimen findings. From January 2000 to November 2002, 52 women with abnormal vaginal bleeding and diagnosed or suspected endometrial cancer were treated in the Department of Obstetrics(More)
Spectral leakage in Fourier transform will influence the accuracy of harmonic analysis for asynchronous sampling. The commonly used windowed interpolated FFT algorithm (WIFFTA) can improve the measurement accuracy by windowing the time samples and interpolating the DFT coefficients, but the accuracy is restricted by the frequency resolution. A new algorithm(More)
Acetals such as methylal and ethylal are shown to be particularely effective additives in improving strenth of wood boards bonded with melamine-urea-formaldehyde a(MUF) resins and they show some appreciable effect on other resins, too, particularely PF resins. The thermomechanical analysis and laboratory particleboard results reported show that acetals(More)
With the development of information technology, it’s possible to deliver advertising more accurately. Online behavioral advertising (OBA) is a kind of advertising which tracks individual online behavior in order to deliver advertising tailored to his or her interests. However, consumers still avoid advertising with more precise delivery. We can’t find out(More)
