The epitaxial structure has a first surface and a second surface opposite to the first surface, and includes a first semiconductor layer, an active layer and a second semiconductor layer that are arranged in such order in a direction from the first surface to the second surface. The conductive layer is formed on a surface of the first semiconductor layer away from the active layer. The first insulating layer is formed on the surface of the first semiconductor layer away from the active layer, and exposes at least a part of the conductive layer.

Abstract: Disclosed is application of acetylacetone in inhibiting the growth of cyanobacteria, that is, acetylacetone is added in water disturbed with cyanobacteria, and the dosage of acetylacetone is not less than 7 mg/L to inhibit the growth of cyanobacteria. Acetylacetone inhibits the growth of cyanobacteria by inhibiting photosynthesis, has a better algicidal effect than common algaecides, is harmless to common bacteria such as Escherichia coli, Salmonella, Bacillus subtilis, and Staphylococcus aureus, and is environmentally friendly and easy to popularize and apply.

Abstract: Querying a data set formed from a version of primary data and secondary data is facilitated. First and second versions of primary data are stored in a primary data version store. Secondary data is received. The secondary data is stored in a secondary data store. A query language statement is received. The query language statement is executed by selecting query results from a data set that includes the secondary data and elements of the first version of primary data not inconsistent with the secondary data.

Abstract: The present invention provides a TiO2-based coagulant and use thereof. The TiO2-based coagulant is obtained by the following steps: uniformly mixing acetylacetone and ethanol and dropwise adding titanium tetrachloride to obtain a solution A; mixing deionized water and ethanol to obtain a solution B; dropwise adding solution B to solution A; stirring to obtain a sol, and then aging the sol to constant weight to obtain the TiO2-based coagulant. The TiO2-based coagulant can be used for treating waste water and algae-laden water. The TiO2-based coagulant exhibits good coagulation effects and high stability, solves the problem of too low effluent pH caused by strong inorganic titanate acidity and is favorable to the subsequent treatment of waste water.

Abstract: This invention relates to the field of molecular physiology. Specifically, this invention relates to the treatment of vasculoproliferative conditions, especially those of the eye and in the treatment of tumours that exhibit vascular proliferation. Levels of leucine-rich alpha-2-glycoprotein (Lrg1) have been demonstrated to be increased in patients suffering from such conditions and animal models of such conditions. Antagonists of Lrg1 can be used to treat vasculoproliferative conditions.

Abstract: Disclosed are a method and a device for detecting traffic signs in an input image camera. The method comprises a color space converting step of converting the input image into a HSV color space image; a filtering step of filtering, based on a predetermined pass range of a standard color of each of the traffic signs, the HSV color space image to obtain a filtered image, and then generating one or more connected domains based on one or more regions in the filtered image; a removing step of removing, based on a standard rule of the corresponding traffic sign, at least one of the generated connected domains, not being the corresponding traffic sign, and letting others of the generated connected domains be candidate traffic sign domains; and a recognition step of recognizing, based on a feature of each of the candidate traffic sign domains, the corresponding traffic sign.
