  • Publication number: 20250084465
    Abstract: Methods and systems described herein involve using long cell-free DNA fragments to analyze a biological sample from a pregnant subject. The status of methylated CpG sites and single nucleotide polymorphisms (SNPs) is often used to analyze DNA fragments of a biological sample. A CpG site and a SNP are typically separated from the nearest CpG site or SNP by hundreds or thousands of base pairs. Finding two or more consecutive CpG sites or SNPs on most cell-free DNA fragments is improbable or impossible. Cell-free DNA fragments longer than 600 bp may include multiple CpG sites and/or SNPs. The presence of multiple CpG sites and/or SNPs on long cell-free DNA fragments may allow for analysis than with short cell-free DNA fragments alone. The long cell-free DNA fragments can be used to identify a tissue of origin and/or to provide information on a fetus in a pregnant female.

  • Publication number: 20240018570
    Abstract: Systems and methods for using determination of base modification in analyzing nucleic acid molecules and acquiring data for analysis of nucleic acid molecules are described herein. Base modifications may include methylations. Methods to determine base modifications may include using features derived from sequencing. These features may include the pulse width of an optical signal from sequencing bases, the interpulse duration of bases, and the identity of the bases. Machine learning models can be trained to detect the base modifications using these features. The relative modification or methylation levels between haplotypes may indicate a disorder. Modification or methylation statuses may also be used to detect chimeric molecules.

  • Publication number: 20230382261
    Abstract: A system or method for vehicle-side control of a multi-pile charging session, the system comprising: (a) a plurality of charging piles (10A), each charging pile (10A) including a supply equipment communication controller (10B); and (b) a vehicle electrical system for an electric vehicle with a master battery control unit (18) in data communication with a plurality of battery control units (BCU0, BCU1, BCU2). The master battery control unit (18) is configured to coordinate two or more independent charging sessions through the battery control units (BCU0, BCU1, BCU2) during each multi-pile charging session. Each independent charging session is managed with an independent protocol message exchange through a BCU-to-SECC communication pathway (22) established by power line communication.

  • Patent number: 11608953
    Abstract: A method for simulating a candle flame with at least one computing device. The method may include controlling at least one lighting element according to at least a current wind value and a current flame value. The method may include controlling the current wind value and the current flame value by iteratively determining whether a first event occurred. When the first event is determined to have occurred, the method may include setting the current wind value to a random wind value and then changing the current wind value toward a baseline wind value. When the first event is determined to have not occurred, the method may include changing the current wind value toward the baseline wind value, determining whether a second event occurred. When the second event is determined to have occurred, the method may include setting the current flame value to a random flame value.

  • Publication number: 20220328135
    Abstract: Systems and methods for determining base modifications using electrical signals and other data is described herein. Embodiments can make use of features derived from electrical signals related to sequencing, such as those acquired from using a nanopore, that are affected by the various base modifications, as well as an identity of nucleotides in a window around a target position whose methylation status is determined. Other features may include a vector of statistical values of a segment of the electrical signal corresponding to the nucleotide and a statistical value of the electrical signal in a window in a region of the nucleic acid molecule. The detected base modifications can be used for additional analysis of a biological sample.
