Patent number: 11963519Abstract: The present disclosure provides a kit and method for constructing a long-acting depression animal model. The present disclosure adopts Bacille Calmette-Guerin (BCG) (or Mycobacterium bovis (M bovis)) and low-dose pertussis toxin (PTX) for combined induction, which greatly reduces modeling cost. A mouse model constructed by the method of the present disclosure can clearly distinguish a time interval of pathological behaviors from a time interval of depression-like behaviors and has prominent face validity and predictive validity. The method of the present disclosure is simple and convenient and does not require a large number of tedious daily operations as the depression model construction by chronic unpredictable stress, chronic restraint stress, social defeat, mother-child separation, or the like. The mouse model of the present disclosure can provide a valuable long-term intervention window for research on antidepressant therapy.Type: GrantFiled: August 25, 2022Date of Patent: April 23, 2024Assignee: Northwest Institute of Plateau Biology, CASInventors: Cen Li, Hongxia Yang, Jing Zhao, Lixin Wei, Yuzhi Du, Yuancan Xiao, Hongtao Bi, Zhanjuan Chen, Yajun Qiao, Jianv Wang

Patent number: 11739996Abstract: A system for controlling or optimizing the performance of a vapor compression system by modifying the actuator commands via an output interface, that realizes thermofluid property functions and their derivatives as spline functions which are represented in a coordinate system that is aligned with a fluid saturation curve. The system includes an interface configured to receive measurement data from sensors, a memory configured to store thermofluid property data and computer-executable programs including a B-spline method, and a processor for performing the computer-implemented method. The processor is configured to take as input two thermofluid property variables, and compute a coordinate transformation in which one axis of the coordinates is aligned with the liquid and vapor saturation curves. In the saturation-curve aligned coordinates, a spline function represents the thermofluid property function, with coefficients and knots stored in memory.Type: GrantFiled: February 18, 2022Date of Patent: August 29, 2023Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Christopher Laughman, Scott Bortoff, Hongtao Qiao
