Publication number: 20240346270Abstract: Molecular anti-counterfeiting taggants are made from a plurality of synthetic polynucleotides that collectively encode a bit sequence using the sequences and hybridization states of the polynucleotides. The polynucleotide taggant is placed on an item as a molecular identifier of authenticity. The bit sequence encoded by the polynucleotide taggant is read out using a substrate which has bound polynucleotides complexes that hybridize with the synthetic polynucleotides in the polynucleotide taggant. A detectable signal is present where hybridization occurs. To prevent a bad actor from reverse engineering and creating a copy of the polynucleotide taggant using the results of hybridization to the substrate, multiple versions of the substrate are created. Each version hybridizes to different subsets of the synthetic polynucleotides in the polynucleotide taggant. A detectable pattern on the substrate that is present when exposed to the polynucleotide taggant is used for validating authenticity of the item.Type: ApplicationFiled: April 17, 2023Publication date: October 17, 2024Inventors: Yuan-Jyue CHEN, Karin STRAUSS, Christian PAQUIN, Alexander Steven CROWN, Sergey YEKHANIN

Publication number: 20240304302Abstract: A system is provided that employs a machine learning (ML) decision tree to provide a treatment analysis for an arrhythmia. The ML decision tree includes decision nodes (non-leaf nodes) and treatment analysis nodes (leaf nodes). Each decision node corresponds to a feature derived from electronic health records and has branches corresponding to feature values. A treatment analysis node corresponds to a treatment analysis based on feature values of a path from the root node to that treatment analysis node. To provide a treatment analysis for a candidate, the system identifies a path from the root node to a treatment analysis node based on a candidate feature vector derived from an electronic health record of the candidate and outputs the treatment analysis of the treatment analysis node of the identified path.Type: ApplicationFiled: March 6, 2024Publication date: September 12, 2024Inventors: Christopher J.
