Sweet potato (Ipomoea batatas L. cv. Lizixiang) is a nutritious arable crop with a low drought tolerance during growth and maturation. The Arabidopsis HOMEODOMAIN GLABROUS 11 (HDG11) gene can increase drought tolerance in tobacco and tall fescue plants. To determine the effect of HDG11 in the sweet potato, transgenic plants that expressed the HDG11 gene(More)
This paper proposes to improve the accuracy of motion vectors for video de-interlacing by selectively using optical flow results to assist the traditional block-based motion estimation used in video codec. Firstly, a framework for performance evaluation is proposed so that the subjective performance of de-interlacing will not matter in applications such as(More)
The catalytic activity of polyaniline-HX (X=I, Br, Cl) (PANI-HI, PANI-HBr, PANI-HCl) for the cycloaddition of CO2 to propylene oxide (PO) to produce propylene carbonate (PC) was studied for the first time. It was shown that all the PANI salts were active for the reaction, and PANI-HI was most active and selective. On the basis of the preliminary results,(More)
In the presence of an easily prepared supported ruthenium hydroxide catalyst, Ru(OH)(x)/Al(2)O(3), various kinds of structurally diverse primary azides including benzylic, allylic, and aliphatic ones could be converted into the corresponding nitriles in moderate to high yields (13 examples, 65-94% yields). The gram-scale (1 g) transformation of benzyl azide(More)
The N-alkylation of ammonia (or its surrogates, such as urea, NH(4)HCO(3), and (NH(4))(2)CO(3)) and amines with alcohols, including primary and secondary alcohols, was efficiently promoted under anaerobic conditions by the easily prepared and inexpensive supported ruthenium hydroxide catalyst Ru(OH)(x)/TiO(2). Various types of symmetrically and(More)
