Abstract: Disclosed are 3,4-methylenedioxyphenylimidazolylethanonexime ether derivatives, a preparation method and use thereof, and a drug for the treatment of Alzheimer's disease, which relates to the technical field of preparation of acetophenone oxime ether compounds. The (Z)-3,4-methylenedioxyphenylimidazolylethanonexime ether derivatives provided by the present disclosure show a significant effect on the inhibition of NO production, with an EC50 of 2.07-5.41 ?mol/L. Compared with the positive control group of quercetin (with an EC50 of 9.56 ?mol/L) and oxiconazole (with an EC50 of 13.5 ?mol/L), the inhibitory effect is stronger without significant cytotoxicity (cell viability >90%), which can be used to prepare drugs for the treatment of Alzheimer's disease.

Abstract: A lubricating element for drag reduction in production and transportation of water-cut heavy oil in a wellbore comprises a flow guide component and a shell component; the flow guide component is fixed in a cyclone chamber of the shell component, and is provided with an intermediate rod to connect and fix a center cone, a flow stabilizing cone and flow guide blades. The lubricating element is a static element integrating three functions of oil-water separation, water control and liquid ring formation, thereby reducing energy consumption for production and transportation of heavy crude oil, and cutting down surface water treatment facilities.

Abstract: Rhizobial infection is the key process for initiating symbiotic nitrogen-fixing root nodules in legumes, which requires specific recognition of signal molecules produced by the bacteria and their hosts. Here, it is established that rhizobial tRNA-derived small RNA fragments (tRFs) are crucial signal molecules modulating host nodulation, which uncovers a bacterial small RNA-mediated mechanism for prokaryote-eukaryote interaction. Transgenic plants are also provided that express a construct encoding rhizobial-derived tRNA, which is subsequently cleaved to produce artificial tRFs. Constructs and methods of producing the same are also provided, as well as modifications for repressing a mechanism for the negative regulation of nodulation present within plants.

Abstract: A search engine identifies external data records that describe similar entities and may each conform to a different data format or source schema. The engine derives mappings capable of translating data values between differently formatted attributes of two source schemas and uses these mappings to identify degrees of similarity between attributes and schemas. When the search engine receives a search request, the engine translates submitted search criteria into values of a first schema's attributes and then uses the mappings to map those values onto selected attributes of other schemas. The search engine then uses each schema's selected attributes to select external data records formatted in that schema. Each selected record is assigned a match score that is weighted by the similarity of the record schema's selected attributes to the search criteria. Records are then retrieved in order of decreasing match score.
