Abstract: A novel composite biological agent based on a porous frame material, comprising porous frame materials and biomolecules. The porous frame materials cover a biological product, wherein the porous frame materials are metal-organic frame material (MOFs), covalent organic frame materials (COFs), and hydrogen-bonding organic frame materials (HOFs), and the biomolecules are any one or a combination of antibodies, enzymes, peptides, vaccines, nucleotides, and virus species. The composite biological agent uses the porous frame materials and biomolecules to form a porous frame material/biomolecule complex, and the biomolecules are coated to achieve the protection effect. Under the premise of remaining biomolecule activity, the system can achieve efficient separation and recovery of the porous materials and the biomolecules, so that the technical problems of synthesis, storage, release, etc. are solved, a good technical effect is achieved, and the biomolecules are effectively protected.

The porous framework material includes one of the metal-organic framework (MOF) material, the covalent organic framework (COF) material and the hydrogen-bonded organic framework (HOF) material. The biomolecules are biological chiral resolving agents. A pore size of the porous framework material is 0.2-15 nm. The porous framework material serves as a solid carrier. The biomolecules are loaded into the porous framework material. The porous framework material is modified with one or more of carboxyl, hydroxyl, amino, aldehyde, double bonds and mercapto groups.

Abstract: Machine-learned model scoring techniques for reducing model invocations are provided. In one technique, first values for non-pair-specific interaction features that are associated with a first entity are identified. Second values for pair-specific interaction features that are associated with (a) the first entity and (b) a second entity that is different than the first entity are identified. A machine-learned model that has been trained based on the non-pair-specific interaction features and the pair-specific interaction features generates a first score based on the first values. The machine-learned model also generates a second score based on the first values and the second values. A final score for the first entity-second entity pair is computed based on the first score and the second score. Based on the final score, data about the first entity is transmitted over a computer network to a computing device associated with the second entity.

The porous framework material efficiently loads a chiral resolving agent (such as proteins, enzymes, or macrocyclic antibiotics) by means of covalent bonding, adsorption, embedding, and crosslinking, such that a variety of efficient and durable chiral stationary phases are prepared to serve as a novel high-performance chromatographic column filler used for chromatographic chiral separation (such as high-performance liquid chromatography or capillary chromatography).
