Abstract: A method for low frequency somatic cell mutation identification and quantification, relating specifically to a method for transposon copy number and genome location identification. Specific sites of different transposon families are used, transposon insertion sequences are specifically enriched via library construction, high-throughput sequencing and bioinformatics analysis are used, and genome locations, copy numbers and types of transposons within samples are accurately identified. The method economically and accurately identifies copy numbers and genome locations of transposons.

Abstract: A three-dimensional (3D) sound localization method, comprising: evaluating distances between a target object and multiple microphones; distinguishing a quadrant in which the target object is located; evaluating multiple elevation angles and azimuth angles of the target object according to spatial coordinates of each of the microphones; setting searching intervals of distance variables between the target object and each of the microphones; generating multiple test points according to the elevation angles, the azimuth angles and the searching intervals of the distance variables; calculating fitness of each of the test points; obtaining fitness values of each of the test points and comparing the fitness values between each of the test points; and, when a convergence condition is reached according to the fitness values, generating a positioning result of the target object.

Abstract: Injectable hydrogel microspheres are prepared by forming an emulsion where hydrogel precursors are in a disperse aqueous phase and polymerizing the hydrogel precursors. In a preferred case, the hydrogel precursors are poly(ethylene glycol) diacrylate and N-isopropylacrylamide and the continuous phase of the emulsion is an aqueous solution of dextran and a dextran solubility reducer. The microspheres will load protein, e.g., cytokines, from aqueous solution.
