Publication number: 20230288405Abstract: Provided are methods for isolating T-cells with T cell receptors (TCRs) optimized for reactivity to specific peptides and decreased cross-reactivity to non-target peptides. Advantageously, TCRs of the invention can be optimized to target cancer antigens and peptides while having reducing reactivity to healthy cells. Methods of the invention utilize a novel combination of culturing conditions that increase T-cell activation and allow for validation of TCR activity. Culturing conditions of the invention further reduce culturing times generally needed to achieve expanded reactive T-cells. Because of the robust nature of the activation and validation conditions of the present invention, variants of identified TCRs can also be optimized and validated for their response to peptides, including cancer peptides.Type: ApplicationFiled: January 20, 2023Publication date: September 14, 2023Inventors: Leah Sibener, Alejandro Ramirez, John Leonard, Marvin Gee, David Victor Liu

Publication number: 20210339399Abstract: A mobile robot is configured to operate in commercial or industrial settings, such as office buildings or retail stores. The mobile robot can have a motorized base, a robot body on the motorized base, and a mechanical arm coupled to the robot body. The mobile robot can move between floors of a building using an elevator. The mobile robot can interact with an elevator system to call an elevator to a current floor, for instance, using the mechanical arm. When a first elevator arrives to the current floor, the mobile robot identifies that doors of the first elevator are opening and interacts with the elevator system again to cause the first elevator to remain at the current floor. After the interaction, the mobile robot moves toward a target location within the first elevator.Type: ApplicationFiled: April 29, 2020Publication date: November 4, 2021Inventors: Erik Schluntz, Travis J.

Patent number: 11046605Abstract: Random copolymers from itaconic acid and/or isomers and sodium alkenyl sulfonates are obtained by polymerization in an aqueous solution via free radicals at an acidic pH in the range from 1.0 to 3.5 and with a redox system as initiator were described. The copolymers can be used as calcium carbonate and calcium, strontium and barium sulfates mineral scale inhibitors and as dispersants of clays, iron oxides, calcium carbonate and strontium, barium and calcium sulfates. Random copolymers prevent and control damage in an oil reservoir, obstruction of water injection and crude oil production pipelines, and in production rigs due to mineral scale precipitation caused by high levels of salinity of the injection water and formation water. Random copolymers are tolerant to high concentrations of divalent ions, such as calcium, magnesium, strontium and barium, and can be added to the reservoir and to injection or production pipelines, treated water, sea water and water that is used as means of transportation.Type: GrantFiled: October 17, 2019Date of Patent: June 29, 2021Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Raul Hernandez Altamirano, Violeta Yasmin Mena Cervantes, Luis Silvestre Zamudio Rivera, Erick Emanuel Luna Rojero, Jose Manuel Martinez Magadan, David Aaron Nieto Alvarez, Mirna Pons Jimenez, Alejandro Ramirez Estrada, Maria del Pilar Arzola Garcia

Publication number: 20200284296Abstract: A gear train includes a housing, a gear, a shaft, a needle bearing, and a stop shim. The housing includes an end face traversing an axis and a cylindrical surface centered to the axis. The face and the surface define a bore. The gear is disposed in the housing, and is adapted to rotate about the axis. The shaft is engaged to, and projects axially from, the gear. The shaft includes an end portion disposed in the bore. The needle bearing is seated in the bore, and is disposed radially between the surface and the end portion. The stop shim is disposed axially between the end face and the end portion for limiting axial displacement of the gear shaft. The stop shim is made of a material that is harder than a material of the housing.Type: ApplicationFiled: March 7, 2019Publication date: September 10, 2020Inventors: Francisco S. Gonzalez, Samuel R.
