Abstract: A method and apparatus for predicting transmission of an infectious disease, a computer apparatus, and a storage medium. The method includes determining one or more objects to be predicted, matching in a historical travel path database for a corresponding predicted path of each of the one or more objects to be predicted, and determining a transmission trend of the infectious disease in the one or more objects to be predicted based on the predicted travel paths. The predicted travel path of each object to be predicted is matched in the historical travel path database thus achieving the effect of reducing the computation amount of obtaining the predicted travel path.

Abstract: Provided are a SiC/ZrC composite fiber, a preparation method and use thereof. The SiC/ZrC composite fiber has a diameter of 10 to 70 μm. The method includes mixing liquid polycarbosilane with a zirconium-containing polymer to obtain a hybrid spinning solution, and then performing electrospinning to obtain a SiC/ZrC composite fiber precursor, crosslinking and thermally treating the SiC/ZrC composite fiber precursor in a protective atmosphere to obtain the SiC/ZrC composite fiber. The SiC/ZrC composite fiber is continuous and uniform, has an adjustable diameter, and thus has outstanding tensile strength and breaking strength and excellent high-temperature resistance. Without use of any organic solvent or spinning agent, the method achieves short process flow and high yield, indicating wide application prospects.

Abstract: A wireless sensor network deployment structure combined with SFFT and COA and a frequency spectrum reconstruction method therefor. The wireless sensor network deployment structure includes: frequency spectrum acquisition sensor nodes dispersed in each region, and a sink node, wherein all the frequency spectrum acquisition sensor nodes have the same structure, and include: a broadband frequency spectrum antenna, a delayer, an ADC, a first baseband processing module, a DAC and a transmitting antenna that are successively connected; all the frequency spectrum acquisition sensor nodes are cooperated to realize SFFT and COA of signals; the signals transmitted by all the frequency spectrum acquisition sensor nodes are superimposed over the air and received by the sink node; and the sink node extracts a data domain from a received signal frame by post-processing, thereby completing frequency spectrum reconstruction. The solution can be easily deployed in an existing wireless sensor network without changing the traditional ADC working mode and communication mode; moreover, the delay is shorter, the sampling rate of the reconstructed frequency spectrum is higher, and the complexity is lower.

Abstract: A method for preparing a fluorescent polarizing film based on directional arrangement of quantum rods. In the method, an inkjet printing technology is used for printing quantum-rod ink having proper viscosity and surface tension on a substrate according to a preset pattern, and directionally arranging quantum rods to obtain a fluorescent polarizing film. The diameter and spacing of fluorescent lines obtained by the method can be controlled and adjusted according to parameter conditions such as a needle aperture, a printing speed, and a preset pattern. The prepared transparent fluorescent film with directionally arranged quantum rods has a high degree of polarization, can be prepared on a flexible substrate in a normal temperature environment, and has wide applicability.
