  • Patent number: 12606669
    Abstract: A biodegradable polymer usable in fishing gear and that biodegrades in aquatic environments. The polymer includes a polymer backbone that has monomeric units that are susceptible to hydrolytic degradation, and a plurality of pH responsive moieties. Each pH responsive moiety is grafted to a respective one of the monomeric units. The pH responsive moieties are relatively hydrophilic when exposed to an aqueous solution of a pro-biodegradation pH range to facilitate hydrolytic degradation of the monomeric units, and are relatively hydrophobic when removed from the aqueous solution of the pro-biodegradation pH range, to protect the monomeric units from hydrolytic degradation.

  • Publication number: 20260094072
    Abstract: A method and system for mitigating predictive multiplicity in a gradient boosting model (GBM). The method includes generating an empirical parameter set based on an approximation search resulting in a subset that includes candidates of at least one weak learner model (WLM) from a predetermined set of WLMs and training iteratively the empirical parameter set to derive a group filtered from the subset based on at least one from among a model selection (MS) technique and an intermediate ensembles (IE) technique. The method also includes selecting sequentially the at least one WLM from the derived group based on the at least one from among the MS technique and the IE technique; and generating the GBM based on a compilation of the sequentially selected at least one WLM, wherein the generated GBM operates below a minimum predefined disagreement threshold related to assessing predictive multiplicity, thereby mitigating the predictive multiplicity.

  • Publication number: 20260073132
    Abstract: Systems and methods for detecting human-generated text and machine-generated text in mixed text are disclosed. A computer program receives a dataset of human-generated text and generates a synthetic mixed text dataset by randomly replacing portions of the human-generated text with machine-generated text. The program evaluates the synthetic mixed text dataset at multiple levels, each representing a different fraction of machine-generated text, and computes a first text discriminator score for each level. Upon receiving a text sample, the program computes a second text discriminator score, fits a kernel density estimate using a Gaussian kernel to model a conditional probability distribution, samples from a posterior distribution, and returns an interval representing the amount of machine-generated text in the sample.

  • Publication number: 20250270653
    Abstract: The present disclosure provides methods and systems for personalized genetic testing of disease in a subject, in particular for identifying and tracking genetic mutations identified in an individual subject to monitor for cancer or for the spread or recurrence of the disease. In some embodiments, custom assays, including custom panels designed to target sequence data corresponding to both subject-specific loci and other loci known for cancer-causing or therapy resistance mutations, are designed based upon the sequencing of a screening biopsy sample. Such custom assays are then run on subsequently obtained tissue samples, such as tissue obtained from a surgical resection of a primary or metastatic tumor or from a lymph node biopsy. The subsequently obtained tissue samples can be taken from the subject at various time points after an initial screening biopsy to further allow for extended monitoring of the subject for spread or recurrence of the disease.

  • Publication number: 20250190465
    Abstract: Systems and methods are provided for providing natural language decision support for pathology. A lower-dimensionality representation of each of a set of received pathology image is generated and a first set of tokens is generated from the representations of the set of pathology images by projecting the lower-dimensionality representations of the received pathology images to a same dimension as an embedding space of a large language model for text tokens or through multimodal blocks added to the large language model such as cross-attention. The large language model is trained on an instruction dataset complied from a plurality of pathology-related sources. A second set of tokens associated with a natural language prompt is received at the large language model. A response is determined from the first set of tokens and the second set of tokens at the large language model.
