  • Patent number: 11959906
    Abstract: A time-ordered series of measurements of a polymer made during translocation of the polymer through a Nanopore are analysed. The measurements are dependent on the identity of k-mers in the Nanopore, a k-mer bring k polymer units of the polymer, where k is a positive integer. The method involves deriving, from the series of measurements, a feature vector of time-ordered features representing characteristics of the measurements; and determining similarity between the derived feature vector and at least one other feature vector.

  • Patent number: 11931074
    Abstract: An embodiment of a uterine hemorrhage controlling system comprises a suction module including a suction end coupleable to a pump by a connecting tube, and a sealing module coupled to the suction module. The system may further comprise the pump and a filter coupled to the suction module. A uterine hemorrhage controlling method comprises: shielding a suction module that has been delivered into a uterus; sealing an entrance into the uterus while the suction module is situated within the uterus; applying a negative pressure within the uterus upon activation of a pump; and maintaining the negative pressure within the uterus to induce uterine contraction. The method may further comprise delivering the suction module into the uterus; transmitting bodily fluids, out of the uterus through the suction module, and filtering the bodily fluids.

  • Patent number: 11921103
    Abstract: A sequence of polymer units in a polymer (3), eg. DNA, is estimated from at least one series of measurements related to the polymer, eg. ion current as a function of translocation through a nanopore (1), wherein the value of each measurement is dependent on a k-mer being a group of k polymer units (4). A probabilistic model, especially a hidden Markov model (HMM), is provided, comprising, for a set of possible k-mers: transition weightings representing the chances of transitions from origin k-mers to destination k-mers; and emission weightings in respect of each k-mer that represent the chances of observing given values of measurements for that k-mer. The series of measurements is analysed using an analytical technique, eg. Viterbi decoding, that refers to the model and estimates at least one estimated sequence of polymer units in the polymer based on the likelihood predicted by the model of the series of measurements being produced by sequences of polymer units.

    Abstract: The disclosure provides various systems and methods for identifying individuals from one or more samples. In particular, improved systems and methods of analysis are provided for handling multiple contributors, as well as systems and methods that model not only individual error rates per locus but factor in amplification of errors induced through PCR cycles. In some embodiments, modeling of error rates can be applied in multi-contributor settings to more accurately establish real alleles from artifacts. Other aspects involve application of sequencing in error modeling. Further, methods are provided for determining the presence of common individual DNA profiles in one or more complex DNA mixtures and for deconvolution of multiple complex DNA mixtures into shared individual components. The methods of the disclosure do not require any prior knowledge of individual DNA profiles or contributors to the complex DNA mixtures.

  • Patent number: 10830443
    Abstract: This disclosure relates to systems and methods for tuning combustion dynamics in a combustor. In one embodiment of the disclosure, a method includes providing, via at least one sensor, combustion dynamics amplitude data associated with a combustor. Method may allow monitoring, by an equipment controller communicatively coupled to the at least one sensor, the combustion dynamics amplitude data. The method may allow detecting at least one change in acoustic pressure amplitude associated with combustion in the combustor. In response to detecting the change in the acoustic pressure amplitude, the method proceeds with determining a fuel split change to at least two fuel circuits configured to supply fuel to the combustor, and applying the fuel split change to the combustor.

  • Patent number: 10816203
    Abstract: A thimble assembly, which directs fluid flow through a combustor liner, includes a thimble boss and a thimble. The thimble boss is mounted an outer surface of the liner and surrounds a liner opening, thus defining a thimble boss passage. The thimble is disposed through the passage and the liner opening. The thimble wall extends from an inlet portion to an outlet of the thimble. The inlet portion has a greater diameter than the outlet and defines an inlet plane and a parallel intermediate plane. A terminal plane, parallel to the intermediate plane, includes an array of points most distant from a corresponding array of points defining the intermediate plane. The thimble wall has a non-uniform length, such that the outlet of the thimble is oriented at an oblique angle relative to the terminal plane. The thimble wall may have an arcuate shape defined as one-fourth of an ellipse.
