Abstract: A white coating material includes 10-70 weight % of hollow glass beads (HGBs) and 30-90 weight % of resin. An intelligent thermochromic coating material includes 10-70 parts by weight of HGBs, 30-90 parts by weight of resin and 0.5-5 parts by weight of reversible thermochromic microcapsules. Due to the rich multi-level cavity structure of HGBs and the inherent characteristics of the polymer, the average reflectivity of the coating layer in the solar spectrum range is as high as 0.96, and the long-wave infrared emissivity can be as high as 0.95. The optical properties, whiteness and hiding power are better than traditional white coating materials based on titanium dioxide. The coating layer added with a small amount of reversible thermochromic microcapsules can switch freely its color between ultra-white and another color as the ambient temperature changes, thereby achieving intelligent adjustment of solar heating and passive radiative cooling.

Abstract: A vortex beam-excited precision grating displacement measurement apparatus, which performs displacement measurement by taking a vortex beam carrying topological charges as an excitation light source of a grating and by using the interference of a ±m-order diffracted vortex beam. In the vortex beam-excited precision grating displacement measurement method and apparatus, the displacement p/m of the measured displacement corresponds to the rotation of a circle 2? rad of an interference petal pattern, and then the rotation of 1° of the interference petal pattern corresponds to the measured displacement amount of p/360m. Compared with a conventional grating measurement method, the present disclosure provides a grating interference sensing signal that realizes a higher optical subdivision rate itself.

Abstract: According to implementations of the subject matter described herein, there is provided a solution for protein structure prediction. In this solution, a constraint set for a target protein is obtained, the constraint set comprising constraints for structural properties of the target protein. Feature information is extracted from the constraints respectively, and weights corresponding to the constraints are determined respectively based on the feature information of the constraints. Each weight indicates a degree of influence of the corresponding constraint in prediction of a structure of the target protein. The structure of the target protein is predicted based on the constraints in the constraint set and the weights. According to the solution, through the pre-processing on the constraints for use, it is possible to solve potential conflicts in the constraint set and eliminate constraint redundancy. This enables accurate prediction of the structure of the target protein.

Abstract: According to implementations of the present disclosure, a solution is proposed for protein structure prediction. In this solution, from a fragment library for a target protein, a plurality of fragments is determined for each of a plurality of residue positions of the target protein. Each fragment comprises a plurality of amino acid residues. Then, a feature representation of structures of the plurality of fragments is generated for the each residue position. Next, a prediction of at least one of a structure and a structural property of the target protein is determined based on the respective feature representations generated for the plurality of residue positions. In this way, the solution can leverage structural information of fragment libraries to complement and complete information used in protein structure prediction, and the accuracy of protein structure prediction is thus improved.
