Abstract: Symmetric spiral configurations of portions of a negative trace and a positive trace with opposite orientations provide for a field cancellation effect in a Wilkinson power divider (or combiner), wherein magnetic fields produced by the positive trace are substantially cancelled out by magnetic fields produced by the negative trace. The geometries of the positive trace and the negative trace effectively produce isolation inductors. Some implementations utilize a transformer, which includes a first positive input port and a first negative input port, an amplifier, and a transformer, which include an input shunt inductor of the differential power divider as part of the transformer.

Abstract: A system and method for determining improved target speeds for accelerated cruise control systems of vehicles. Data is obtained by human-operated ego vehicles, the data including ego-vehicle speeds, lead-vehicle speeds, follow distances, and location tuples of the ego vehicles, such as GNSS coordinates. The location tuples are mapped to lane centerpoints of a high-definition map.

The trained model can be implemented as part of an accelerated cruise control system in a vehicle.

Abstract: An autonomous mobile device (AMD) moves within in a physical space. The AMD may encounter features in the physical space, such as flooring transitions, or obstacles that may impede movement. Sensors such as an ultrasonic sensor, optical time of flight sensors, inertial measurement unit (IMU), wheel speed sensors, and motor torque sensors acquire sensor data. Based on the sensor data, a location of an obstacle, and characterize whether that obstacle is traversable or non-traversable, is determined. If traversable, the AMD may continue moving past the obstacle. If non-traversable, the location of the obstacle may be added to a map used for route planning. Based on the location of the non-traversable obstacle, the AMD may move to a recovery location away from the obstacle, and resume moving.

Abstract: A fusion protein with the amino acid sequence of SEQ ID NO: 1 and the nucleic acid molecule (SEQ ID NO: 3) including an encoding gene of a chimeric antigen receptor and an encoding gene of a chimeric switch receptor are provided. By designing fusion gene containing the encoding gene of the chimeric antigen receptor and the encoding gene of the chimeric switch receptor, PD-L1 activated inhibition of anti-tumor T cell responses is converted into a CD27-mediated activation signal, thereby endowing CAR-T cells with the capability of resisting an immunosuppressive tumor microenvironment, thereby enhancing its in vivo persistence. In addition, the micro-environment near a tumor is regulated by promoting secretion of cytokines IFN-? and IFN-?2 to relieve the immunosuppression thereof, thereby mobilizing the organism autoimmunity to participate in the killing effect on tumor cells, and improving the anti-tumor effect of the CAR-T cells.

Abstract: The present disclosure describes techniques of performing machine unlearning in a recommendation model. An unlearning process of the recommendation model may be initiated in response to receiving a request for deleting a fraction of user data from any particular user.

Confidence values associated with the fraction of user data may be configured as zero to block influence of the fraction of user data on performance of the recommendation model. The unlearning process may be implemented by performing a number of iterations until the recommendation model has converged.
