  • Patent number: 11842544
    Abstract: A method may include obtaining an image of a scene from a first perspective, the image including an object, and detecting the object in the image using a machine learning process, where the object may be representative of a known shape with at least four vertices at a first set of points. The method may also include automatically predicting a second set of points corresponding to the at least four vertices of the object in a second perspective of the scene based on the known shape of the object. The method may additionally include constructing, without user input, a transformation matrix to transform a given image from the first perspective to the second perspective based on the first set of points and the second set of points.

  • Publication number: 20230390220
    Abstract: Monoamine oxidase A (MAO-A) is an enzyme best known for its function in the brain, where it breaks down neurotransmitters and thereby influences mood and behavior. While small molecule MAO inhibitors (MAOIs) have been developed used for treating depression and other neurological disorder, the involvement of MAO-A in antitumor immunity has not been known. The disclosure provided herein identifies MAO-A as an immune checkpoint and the use of MAOI antidepressants for cancer immunotherapy. Here we report induction of the Maoa gene in tumor-infiltrating immune cells. MAOI treatment significantly suppressed tumor growth in preclinical mouse syngeneic and human xenograft tumor models in a T cell-dependent manner. Combining MAOI and anti-PD-1 treatments generated synergistic tumor suppression effects. Clinical data correlation studies associated intratumoral MAOA expression with T cell dysfunction and impaired patient survival in a broad range of cancers.

  • Publication number: 20230391871
    Abstract: We have discovered MAO-A induction in mouse and human TAMs. Moreover, we determined that MAO-A-deficient mice exhibited decreased TAM immunosuppressive functions corresponding with enhanced antitumour immunity. Building upon these discoveries, we then determined that MAOI treatment induced TAM reprogramming and suppressed tumour growth in preclinical mouse syngeneic and human xenograft tumour models. Surprisingly, combining MAOI and anti-PD-1 treatments resulted in synergistic tumour suppression. Together, these data identify MAO-A as a critical regulator of TAMs, and that show that repurposing MAOIs for TAM reprogramming can be used to improve cancer immunotherapies.

  • Publication number: 20230184045
    Abstract: The present disclosure provides a device and method for diagnosing risk of insufficient hole cleaning problem during drilling wells. The method includes obtaining the measured pressure via several measuring points, and obtaining actually measured value of each measuring point; calculate the theoretical pressure at each measuring points by using the real-time operational data as inputs, evaluating a hole cleaning condition by applying a difference between a theoretical pressure drop and a measured pressure drop to a developed pressure driven hole cleaning model, which gives the risk of insufficient hole cleaning problems and problematic locations. The theoretical pressure drop between two adjacent measurement points along wellbore includes the pressure drop caused by friction effect and hydrostatic effect. However, suspended cuttings in actual drilling fluid may significantly change the pressure drop along wellbore.
