  • Publication number: 20230288405
    Abstract: 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.

  • Patent number: 11475760
    Abstract: In order to detect movements of objects and/or living beings in a radio range, which enables easily with a minimum of hardware complexity an automated movement detection based on a Single-Sensor, it is proposed to: Collect as input data for the movement detection based on received radio signals of an intended or unintended communication between a transmitting radio terminal being mobile or fixed and a receiving local fixed radio device in the radio range a set of “Channel State Information”-values, determine a change in the received radio signals, which are derived from the facts that the movement influences the transmitted radio signal in the radio range based on the collected CSI-values by the indication of a statistical parameter value, and assess on the basis of the statistical parameter value a “chaos index” value until the “chaos index” value in accordance with a threshold check provides a reliable statement.

  • Publication number: 20210339399
    Abstract: 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.

  • Patent number: 11046605
    Abstract: 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.
