Abstract: A glycoside conversion method based on high-speed countercurrent chromatography, relating to the technical field of glycoside conversion, and specifically relating to a use of a high-speed countercurrent chromatograph in the bioconversion of a glycoside component. In the present method, a high-speed countercurrent chromatograph serves as a reactor for performing a bio-enzyme conversion reaction on a glycoside component, differences in the distribution of the glycoside and an aglycone in two solvent phases are utilized, a glycoside hydrolase is added in advance to an aqueous phase solution as a stationary phase, and a glycoside substrate to be converted is added into a mobile phase. During operation of the countercurrent chromatograph, the enzyme is located in the stationary phase, and because the substrate glycoside more readily dissolves in the aqueous solution, in a mobile process, the glycoside enters the stationary phase from the mobile phase and undergoes a complete enzymolysis reaction with the glycoside hydrolase to produce a micromolecule aglycone, and the produced aglycone flows out with the mobile phase, completing the process of bioconversion and separation. In the present method, a high-speed countercurrent chromatograph serves as a bioconversion reactor, allowing conversion and separation to be completed at the same time, and allowing inhibiting effects to be eliminated from the enzymolysis reaction process, increasing the conversion rate.

Abstract: A binary multi-band power distribution (BMBPD)-based low signal-to-noise ratio sound event detection method, which uses a combination of BMBPD and random forest (RF) to provide excellent performance. The BMBPD binarizes pixels the grayscale of which is less than a certain threshold in an MBPD image to 1, and the remainder to 0, which may highlight pixels related to a sound event in the MBPD image while suppressing the influence of noise, thereby reducing the influence of noise in a low signal-to-noise ratio environment on a sound event to be measured. By means of performing discrete cosine transform (DCT) on an BMBPD image block, a main part of Z encoding of a DCT coefficient is used as a feature of the sound event, i.e. BMBPD-DCTZ, and an RF classifier is used to train and detect the BMBPD-DCTZ. The method has a wide range of applications to sound levels and has strong robustness in severe non-stationary noise.
