  • Patent number: 11961589
    Abstract: A processing system uses a Bayesian inference based model for targeted sequencing or variant calling. In an embodiment, the processing system generates candidate variants of a cell free nucleic acid sample. The processing system determines likelihoods of true alternate frequencies for each of the candidate variants in the cell free nucleic acid sample and in a corresponding genomic nucleic acid sample. The processing system filters or scores the candidate variants by the model using at least the likelihoods of true alternate frequencies. The processing system outputs the filtered candidate variants, which may be used to generate features for a predictive cancer or disease model.

  • Publication number: 20240117435
    Abstract: Systems and methods for predicting survival outcomes in patients diagnosed with Myelodysplastic Syndrome (MDS) are disclosed. One method may include: receiving DNA sequencing data derived from a methylation assay performed on a biological sample associated with the at least one patient; computing methylation beta-values for one or more CpG-sites identified in the sequencing data; identifying one or more differentially methylated regions (DMRs) based on statistical analysis of the methylation beta-values for the one or more CpG-sites; selecting, via a feature selection process, a subset of the one or more DMRs to utilize as training data; and training, using the training data, the classifier to predict the survival outcome of the at least one patient. Other aspects are described and claimed.

  • Patent number: 11927519
    Abstract: Synthetic human cell mimic hydrogel particles and their use in cytometric or coulter device applications are described. The synthetic human cell mimic hydrogel particles described herein are selectively tunable to have at least one optical, volumetric, or capacitance property that is substantially similar to a corresponding optical, volumetric, or capacitance property of the human cell mimic hydrogel particle's natural biological cell counterpart.

  • Publication number: 20230298029
    Abstract: A method of evaluating a merchant cash advance option may include receiving time series information including a plurality of signals representing transactions of merchants and customers where at least one of the signals relates to product returns. The method may further include aggregating the time series information, generating a plurality of trained models associated with the product returns, employing a selected model to forecast return volume and repurchase volume for a given merchant, determining a risk assessment value for the given merchant, and, if the risk assessment value is below a risk threshold, providing an offer of a merchant cash advance to the given merchant based on the forecast return volume and repurchase volume.

  • Publication number: 20230297943
    Abstract: A method of facilitating a product return transaction may include receiving product return data from a merchant indicating merchant-specific information on product returns to the merchant and receiving an indication of a product return request from a customer. The method may further include employing a trained model to determine a likelihood of return rating associated with physical receipt of a returned product associated with the product return request based on the product return data, responsive to the likelihood of return rating exceeding a threshold, extending a credit to the customer based on a value of the returned product, and enabling the customer to initiate a product repurchase using the credit.
