  • Patent number: 11973657
    Abstract: A system may receive enterprise information associated with a client enterprise. The system may select, using an industry analysis model, a set of queries associated with obtaining status information that is associated with a technology profile of the client enterprise. The system may generate client data that is associated with the enterprise information and the status information. The system may convert, using a matrix factorization technique, the client data associated with the client enterprise to a client matrix. The system may convert, using the matrix factorization technique, reference data associated with reference enterprises to a reference matrix. The system may determine, based on a comparison of the client matrix and the reference matrix, a set of scores associated with technology metrics of the technology profile. The system may perform an action associated with the client enterprise based on the set of scores.

  • Publication number: 20230038792
    Abstract: Aqueous mixtures can include cellulose nanocrystals and sulfonated polyester, where a glass transition temperature (Tg) of the sulfonated polyester is greater than 25° C. In some instances, exemplary aqueous mixtures also include one or more additives, such as pigment. Exemplary aqueous mixtures can be applied as a film that is typically hydrophobic and resilient against water at room temperature. Upon application of warm water, such as at temperatures of from about 30° C. to about 60° C., the film can be removed with no or limited abrasion and/or with no or little removal oils.
