Abstract: A method for preparing a tumor-derived microparticle by a microwave includes the following steps: step 1, Lewis lung carcinoma (LLC) of a lung adenocarcinoma cell line is taken and then the LCC is cultured in a culture dish for more than 24 hours (h) to obtain cultured cells; step 2, microwave heating treatment is performed on the cultured cells obtained in step 1 to obtain treated cells; step 3, the treated cells obtained in step 2 are placed into a constant temperature incubator for cultivation for 24 h; and step 4, a supernatant of cells is collected from the culture dish cultured in step 3, and multiple centrifugation treatments is performed on the supernatant by using a density gradient centrifugation method to obtain a precipitate which is the tumor-derived microparticle TMPMW.

Abstract: This application provides a task scheduling method, an electronic device, a chip system, and a storage medium, and relates to the field of task scheduling technologies. The method includes: In some quick response scenarios of the electronic device, for example, in a stylus scenario, some or all threads that support the scenario are set to run on a processor core with a higher computing capability, so that the processor core with a higher computing capability can quickly process the threads. In addition, after the scenario ends, the thread may be further switched from the processor core with a higher computing capability back to an original processor core.

Abstract: A polynucleotide having promoter activity of a malate dehydrogenase gene (mdh gene), a transcription expression cassette, recombinant expression vector and recombinant host cell containing the polynucleotide having the promoter activity, a method for constructing a promoter mutant, a method for regulating the transcription of a target gene, a method for preparing a protein, and method for producing a target compound. The polynucleotide having the promoter activity is a mutant of an mdh gene promoter, and compared with a promoter of a wild-type mdh gene, the promoter activity of the mutant is significantly improved. After operably linking the mutant to a target gene, the expression efficiency of the target gene can be significantly improved, thereby effectively improving the yield and transformation rate of a target compound.

Abstract: Disclosed herein are systems and methods that describe a noise-shaping (NS) SAR architecture that can be simple, effective, and low power. In an aspect, a method includes the operation of receiving a first analog input; determining a first digital output based on the first analog input; obtaining a first quantization error for the first digital output; integrating the first quantization error; receiving a second analog input; and determining a second digital output based on the summation of the second analog input and the first integrated quantization error to perform noise-shaping.
