    Abstract: The invention provides a method, apparatus, device and storage medium for predicting a protein binding site. The method comprises the steps of: receiving a protein sequence to be predicted, dividing the protein sequence by using a preset sliding window and sliding step to obtain a plurality of amino acid sub-sequences, building word vectors for the protein sequence according to the amino acid sub-sequences, extracting document features from word elements, building document feature vectors for the protein sequence according to the extracted document features, extracting protein chain biological features from the amino acid sub-sequences, building biological feature vectors for the protein sequence according to the extracted biological features, classifying the amino acid sub-sequences expressed with the document feature vectors and the biological feature vectors by using a preset amino acid residue classification model to obtain amino acid residue types for the protein sequence.

    Abstract: The present disclosure provides a multi-arm spacecraft model predictive control method based on the mixture of Gaussian processes, equipment, and a medium. Model predictive control has excellent performance in dealing with complex nonlinear systems such as multi-arm spacecrafts with various constraints, and is widely applied to ground robots, unmanned aerial vehicles, autonomous driving and other practical scenarios. Therefore, a task space controller is designed based on the model predictive control in the present disclosure. Besides, in order to enhance the anti-interference capability of the present disclosure, an interference model is established and compensation is carried out in the model predictive control by utilizing the characteristics of small training data volume and high training speed in the mixture of Gaussian processes. Finally, a thrust distribution method is designed to complete platform control. The method provided by the present disclosure is convenient and intuitive in design and has relatively high practicability.

    Abstract: Disclosed is an aqueous fluorescent ink and a preparation method and use thereof. The aqueous fluorescent ink provided by the present disclosure includes 0.10%-0.14% of polystyrene micro-spheres, 0.010%-0.014% of fluorescent dyes, 0.4%-0.6% of surfactants, and the balance of water. The present disclosure uses polystyrene micro-spheres as a fluorescent dye carrier, which is colorless and transparent under ordinary daylight and completely invisible, and displays fluorescence only when irradiated by ultraviolet light and has high fluorescence intensity. The surfactant makes the polystyrene fluorescent micro-spheres uniformly dispersed in the fluorescent ink, and the stability of the fluorescent ink is improved. Water is used as a solvent, which has excellent safety and environmental friendliness. The accuracy of the printed patterns can reach 30 μm, which can help realize large-format ultra-high-precision patterned anti-counterfeiting encryption printing. Through precision printing, the two-dimensional code can be implemented with one code for one object, and has excellent anti-counterfeiting ability.
