Abstract: A method for supporting aerial operation includes obtaining a real-time location of an aircraft, obtaining a location of a supply station, obtaining a location of a next waypoint, and controlling the aircraft based on a status parameter related to a flight status of the aircraft associated with the real-time location of the aircraft. Controlling the aircraft includes controlling, in response to the status parameter satisfying a first preset condition, the aircraft to fly to the next waypoint; and controlling, in response to the status parameter satisfying a second preset condition, the aircraft to fly to the supply station.

Abstract: An intelligent smog-penetrating optical imaging detection device and a method of thereof, and belongs to the technical field of photoelectric imaging. The intensity information, the spectrum information, and the polarization information of light are organically combined, the three functions of intensity imaging, spectrum imaging and polarization imaging can be achieved, traditional imaging detection is beneficially supplemented, smog can be penetrated, the image contrast of imaging is improved, and therefore the working distance is increased. The intensity information reflects the detection distance, the target shape, the target size and the like; the spectrum information reflects material components, surface morphology and the like of a space target; the polarization information reflects the material and roughness of the target and the contrast with the background; and the intensity, spectrum and polarization three-dimensional information is jointly applied, the image contrast can be increased by 2-3 times.

Abstract: A hydrogel for cell-laden bioprinting, bioink, and a preparation method and an application thereof, relates to the technical field of biomedical polymer hydrogels. The hydrogel for cell-laden bioprinting is polymer gel formed by adding a cell-specific material into a matrix of alginate and gelatin and crosslinking and curing, wherein the cell-specific material is polypeptide selected according to different laden cells. The structures printed using the hydrogel may have the advantages such as adjustable mechanical properties, adjustable porosity, high biocompatibility, high printing accuracy, and high customizability, which may widely support the printing of human tissues and organs such as spinal cord, cartilage, and heart, and has good prospects for applications in tissue repair, organ transplantation and so on.
