  • Publication number: 20190234937
    Abstract: Described herein are in vitro cancer metastasis models that recapitulate biological facets of organ specificity as indicated by the behavior of human colorectal cancer cells when on substrata of liver and lung biomatrix scaffolds, organ-specific matrix extracts generated by novel decellularization strategies. Tumor cells spontaneously formed colonies that mimicked in vivo metastatic lesions in terms of histology, biology and genetic and other phenotypic traits. Not to be bound by theory, it is postulated that responses of tumors to radiation or chemotherapeutic agents proved dependent on the matrix substratum used; thus, thus the scaffolds are believed to provide a powerful tool for cancer research and diagnosis.

  • Publication number: 20180218287
    Abstract: An online system receives content items, for example, from content providers and sends the content items to users. The online system uses machine-learning models for predicting whether a user is likely to interact with a content item. The online system uses stored user interactions to measure the model performance to determine whether the model can be used online. The online system determines a baseline model using stored user interactions. The online system determines whether the machine-learning model performs better than the baseline model or worse for each content provider. The online system determines whether to approve the model for online use based on an aggregate normalized performance metric, for example, a metric representing the fraction of content providers for which the model performs better than the baseline. If the online system determines to reject the model, the online system retrains the model.
