  • Publication number: 20220229959
    Abstract: The present invention relates to an injection-production relationship optimization method based on heterogeneous flow field characterization. The method comprises the steps of: first, calculating a density of a flow field by adopting a method of converting a linear density into a dot density; then, calculating an intensity of the flow field by adopting an analytic hierarchy process; and performing flow field characterization by utilizing mathematical methods such as PCA dimensionality reduction and clustering and calculating a product of flow line densities and intensities of flow fields in different regions of the flow field, and performing optimization for a goal of minimizing a variance of the product in combination of an genetic algorithm to solve the optimum injection-production quantity as an optimum solution (the optimum injection-production quantity) that enables the flow field to be displaced in a balanced manner.

  • Patent number: 11389446
    Abstract: A theranostic agent can be used in both photoacoustic imaging (PAI) and photothermal therapy (PTT) applications. The theranostic agent can include a small molecule, organic compound with absorption in the near-infrared (NIR) interrogation window (700-900 nm). The compound can be a biocompatible organic nanoparticle (ONP). The theranostic agent can be effectively used in PAI and PAI-guided PTT applications. The theranostic agent can be administered to a patient to locate a tumor site in the patient using in vivo imaging techniques. Once the tumor site has been determined, the tumor site can be irradiated with near-infrared light to stop or inhibit the growth of the tumor.
