Abstract: A high-nickel ternary core-shell precursor for a lithium battery, a positive electrode material and a preparation method therefor. The chemical structural formula of the precursor is zNi(C4H7N2O2)2—Nix-zM1yM21-x-y(OH)2, wherein M1 and M2 are two of cobalt, aluminum, and manganese. The preparation method comprises: pumping a prepared metal salt solution, a dimethylglyoxime-ammonia water composite solution, and an ammonia water solution into a reaction kettle, maintaining the pH of a reaction system, and controlling the reaction time to obtain a sphere-like precursor inner core with a structural formula of Ni(C4H7N2O2)2; pumping the metal salt solution and the ammonia water solution, stopping pumping the dimethylglyoxime-ammonia water composite solution, pumping a sodium hydroxide solution to obtain a sphere-like core-shell precursor, washing, drying, sieving and deironing the precursor, mixing with a lithium source, and calcining to prepare the positive electrode material.

Abstract: System and method for sensing movement such as chest movement of each of a plurality of target test subjects by: transmitting, at each of N transmitting antennas (TXs) of a phased multiple-input multiple-output (phased-MIMO) radar, a common frequency modulated continuous wave (FMCW) signal in each of a plurality of time division multiplex (TDM) slots, each TDM slot having associated with it a respective weight selected in accordance with a transmit steering vector configured to cause a coherent summation of transmitted signal in a desired direction ?0 toward at least one target; receiving target-reflected energy associated with the transmitted FMCW signals at a virtual array formed by stacking signal from P TDM slots received via M receiving antennas (RXs) of the phased-MIMO radar; and processing an output of the virtual array to extract therefrom signal received from the desired direction ?0 to determine thereby target movement in the desired direction ?0.

Abstract: The disclosure belongs to the field of biotechnology, and in particular to a blocking ELISA kit for detecting an antibody to swine acute diarrhea syndrome coronavirus (SADS-CoV) N protein. The kit includes an enzyme plate coated with SADS-CoV N protein, an HRP-labeled mouse anti-SADS-CoV N protein monoclonal antibody (mAb), a positive serum control, and a negative serum control. The kit may detect positive sera diluted at 1:512, with no cross-reaction with positive sera against porcine epidemic diarrhea virus (PEDV), transmissible gasteroenteritis virus (TGEV) and porcine deltacoronavinis (PDCoV) etc., and the intrabatch and interbatch coefficient of variation is less than 10%. The comparison result with the indirect immunofluorescence test shows that the concordance rate of the blocking ELISA kit of the present disclosure is 99.6%, the Kappa value is 0.91, and the blocking ELISA method established by the present disclosure is highly consistent with IFA.
