  • Patent number: 11744861
    Abstract: Disclosed are methods of eliminating at least on target cell in a subject, comprising administering to the subject an effective amount of a composition comprising a plurality of immune cells, wherein each immune cell of the plurality expresses one or more chimeric ligand receptor(s) (CLR(s)) that each specifically bind to a target ligand on the at least one target cell, wherein specifically binding of the one or more CLR(s) to the target activates the immune cell, and wherein the activated immune cell induces death of the target cell. Exemplary target cells include, but are not limited to, hematopoietic stem cells (HSCs).

  • Patent number: 10451417
    Abstract: A method for acquiring a remote object is provided. The method comprises obtaining a sequence of position samples of the remote object, identifying one or more sets of spatially clustered position samples from among the obtained position samples, and applying curve-fitting to at least one set of spatially clustered position samples to obtain a trajectory of the set of spatially clustered position samples. Also provided is a method for tracking a remote object. The method comprising obtaining an estimated trajectory of the object, obtaining one or more position samples of the object, comparing the obtained position samples with positions computed based on the estimated trajectory, and determining that the object is being tracked based on whether the obtained position samples are consistent with the computed positions.

  • Patent number: 9957439
    Abstract: Friction reducers for hydraulic fracturing fluids, hydraulic fracturing fluids containing the friction reducers, and methods of making and using same are disclosed. The friction reducers comprise ethylene oxide polymers, propylene oxide polymers, ethylene oxide-propylene oxide co-polymers, and combinations thereof, and can further comprise a dispersant, such as polypropylene glycol. The friction reducer formulations can be active across a wide range of brine salinities, and tolerant of high levels of divalent cations in solution. The friction reducers can have a cloud point temperature, above which temperature they can precipitate out of solution and deposit on a surface of a hydrocarbon-bearing formation to inhibit hydration of the shale formations lining the fractures.
