  • Patent number: 11473088
    Abstract: Various aspects of the present invention relate to a method of treating cancer in a subject having cancer cells, wherein the cancer cells possess at least one growth hormone receptor, and wherein the method includes controlling an action of the growth hormone receptor. In various non-limiting embodiments, controlling an action of the growth hormone receptor may occur via knock down of the growth hormone receptor, or may be caused by inhibiting growth hormone action, such as via the use of antibodies directed against growth hormone or the growth hormone receptor. Methods may also relate to administering an antagonist of the growth hormone receptor, and administering at least one anti-tumor drug in concert with administration of the antagonist. Another aspect may include a method of maintaining an anti-tumor drug in cancer cells of a subject by controlling an action of at least one growth hormone receptor in the cancer cells.

  • Patent number: 11419541
    Abstract: Methods of patient-specific modeling of the mechanical properties of bone and related systems. The methods include obtaining a bending stiffness (K) of a bone specimen non-invasively and non-destructively in a dynamic 3-point bending test, creating a mathematical mechanical model of the bone specimen, assigning an elastic modulus (E) to the bone specimen of the mathematical mechanical model, determining the flexural rigidity of the bone specimen from simulating the mathematical mechanical model, determining a discrepancy between the flexural rigidity of the bone specimen from the simulated mechanical model and based on the obtained K, adjusting the elastic modulus of the simulated mechanical model to minimize the discrepancy, adjusting the elastic modulus until an optimized elastic modulus is determined where the discrepancy is reduced below a predetermined threshold, and applying the optimized elastic modulus to the simulated mechanical model to determine a strength of the bone.

  • Patent number: 11366478
    Abstract: Systems, methods, and computer program products for autonomous car-like ground vehicle guidance and trajectory tracking control. A multi-loop 3DOF trajectory linearization controller provides guidance to a vehicle having nonlinear rigid-body dynamics with nonlinear tire traction force, nonlinear drag forces and actuator dynamics. The controller may be based on a closed-loop PD-eigenvalue assignment and a singular perturbation (time-scale separation) theory for exponential stability, and controls the longitudinal velocity and steering angle simultaneously to follow a feasible guidance trajectory. A line-of-sight based pure-pursuit guidance controller may generate a 3DOF spatial trajectory that is provided to the 3DOF controller to enable target pursuit and path-following/trajectory-tracking. The resulting combination may provide a 3DOF motion control system with integrated simultaneous steering and speed control for automobile and car-like mobile robot target pursuit and trajectory-tracking.

  • Patent number: 11360058
    Abstract: A method of quantifying a target compound includes applying an oxidation/reduction potential to an electrochemical cell (14); measuring an electrochemical current during the application of the oxidation/reduction potential; and ionizing and directing the target compound before and after the application of the oxidation/reduction potential to a mass spectrometer (16) that measures a target compound ion intensity. The method further includes determining a target compound ion intensity change due to the application of the oxidation/reduction potential and determining a total amount of the target compound in the sample using the measured electrochemical current and the target compound ion intensity change. Determining the target compound ion intensity change may comprise either comparing the target compound ion intensity before and after the electrolysis relative to a reference peak or comparing the integrated peak area of a target compound ion in an extracted ion chromatogram before and after the electrolysis.
