    Abstract: A computer-implemented method includes encoding a radiance field of an object onto a machine learning model; conducting, based on a set of training images of the object, a training process on the machine learning model to obtain a trained machine learning model, wherein the training process includes a first training process using a plurality of first test sample points followed by a second training process using a plurality of second test sample points located within a threshold distance from a surface region of the object; obtaining target view parameters indicating a view direction of the object; obtaining a plurality of rays associated with a target image of the object; obtaining render sample points on the plurality of rays associated with the target image; and rendering, by inputting the render sample points to the trained machine learning model, colors associated with the pixels of the target image.

    Abstract: A method for catalytic synthesis of ammonia under normal pressures, including: performing a reaction of hydrogen and nitrogen to synthesize ammonia under normal pressures by taking a liquid alloy as a catalyst in a reactor, where the reactor contains a molten salt, the density of the molten salt is smaller than that of the liquid alloy, and the molten salt is used for providing a reaction interface and isolating the liquid alloy from being introduced impurities. The first metal can react with the nitrogen to produce the metal nitride, and the molten salt can provide a new reaction interface for the metal nitride to react with the hydrogen to synthesize the ammonia, so that the metal nitride can continuously generate the ammonia, and the synthesis of the ammonia can be effectively catalyzed. In addition, the molten salt can prevent the liquid alloy from contacting with the oxygen and the water vapor of the outside atmosphere, thereby preventing the liquid alloy from being oxidized and prolonging the service life of the liquid alloy.

    Abstract: A preparation method for mutant cells with deletion of target genes, at least comprising the following steps: (1) transfecting a sgRNA group into same host cells, where the sgRNA group includes two sgRNAs that target different sites of a same target gene, and the number of the sgRNA group may be one or more than one. When the number of the sgRNA group is more than one, each different sgRNA group targets one different target gene. (2) Enriching the host cells expressing one or more sgRNA groups. (3) Culturing the host cells obtained from step (2) to produce mutant cells with deletion of target genes.

    Abstract: Disclosed is a nucleic acid test kit, comprising a Cpf1 test system, said Cpf1 test system comprising: a guide RNA, a Cpf1 protein, a nucleic acid probe, and a manganese ion-containing solution. Also provided is a mutated Cpf1 protein and a nucleic acid test kit containing the mutated Cpf1 protein. Also provided is a crRNA for testing coronavirus nucleic acid, and a nucleic acid test kit containing said crRNA. Further provided is a use of the nucleic acid test kit, and a test method for the nucleic acid. When the nucleic acid test kit, mutated Cpf1 protein, or crRNA of the present invention are used for nucleic acid testing (for example, testing the nucleic acid of a SARS-related coronavirus or MERS coronavirus), the signal strength during the test is substantially enhanced, and the test time is thus reduced and the test efficiency improved. In addition, the sensitivity, specificity, and accuracy are high, the test is visual, the cost is low, the operation is simple and convenient, and no large-scale complex t equipment is required.

    Abstract: Example embodiments relate to methods for disseminating scaling information and applications thereof in very large scale integration (VLSI) implementations of fixed-point fast Fourier transforms (FFTs). One embodiment includes a method for disseminating scaling information in a system. The system includes a linear decomposable transformation process and an inverse process of the linear decomposable transformation process. The inverse process of the linear decomposable transformation process is defined, in time or space, as an inverse linear decomposable transformation process. The linear decomposable transformation process is separated from the inverse linear decomposable transformation process. The linear decomposable transformation process or the inverse linear decomposable transformation process is able to be performed first and is defined as a linear decomposable transformation I. The other remaining process is performed subsequently and is defined as a linear decomposable transformation II. The method for disseminating scaling information is used for a bit width-optimized and energy-saving hardware implementation.
