Modified sleeping beauty transposase polypeptide with increased solubility for transfection into cells as an isolated protein
This disclosure provides improved reagents and methods for inserting a transgene into the genome of a living host cell. Sleeping beauty (SB) transposase is used in protein form rather than as a vector.

The changes increase solubility while maintaining transposase activity, thereby adapting the variant transposase for the purpose of promoting recombinant integration of a transgene into a target cell when used in protein form rather than as a polynucleotide vector. The modified transposase is highly soluble in electroporation buffer and thermostable during storage. When introduced into a host cell, it promotes integration of a transgene into the genome of the cell in a dose-dependent manner. It is degraded within 48 hours, thereby rapidly clearing transposase activity from the host cell. |

Method for operating an air conditioning system for a vehicle, and air conditioning system arrangement
A method for operating an air conditioning system for a vehicle for transporting persons. The air conditioning system, depending on the current number of passengers in a passenger compartment of the vehicle (level of occupation), controls a fresh air volume flow to be introduced into the passenger compartment from outside the vehicle in order to maintain a predefined minimum ambient air quality. The air conditioning system determines a total water mass flow, which is currently produced by the passengers in the passenger compartment, on the basis of air-conditioning measurement values and a current value for at least one operating parameter of the air conditioning system. From the total water mass flow and a predefined value for a water mass flow produced by a single passenger, the system determines the current number of passengers in the passenger compartment. There is also described an air conditioning arrangement for carrying out the method. |

Remote vehicle guidance
Techniques for providing remote guidance to a vehicle operating in an environment, by an operator located in the environment, are described herein. The operator can include a safety observer configured to observe one or more vehicles operating in the environment and may identify a scenario that requires a modification to a vehicle operation (e.g., stop forward movement, change direction of travel, modify a maximum speed, etc.). The operator may access a graphical user interface (GUI) via an operator computing device, and may input a constraint to modify the vehicle operation. The vehicle computing system may receive a control signal including the constraint, and may modify a vehicle trajectory based on the constraint. The vehicle computing system may later determine that a condition associated with the constraint is satisfied, and may continue vehicular operation in absence of the constraint. |

Distributional expert demonstrations for autonomous driving
The present disclosure provides methods and techniques for evaluating and improving algorithms for autonomous driving planning and control (PNC), using one or more metrics (e.g., similarity scores) computed based on expert demonstrations. For example, the one or more metrics allow for improving PNC based on human, as opposed to or in addition to optimizing certain oversimplified properties, such as the least distance or time, as an objective. When driving in certain scenarios, such as taking a turn, people may drive in a distributed probability pattern instead of in a uniform line (e.g., different speeds and different curvatures at the same corner). As such, there can be more than one “correct” control trajectory for an autonomous vehicle to perform in the same turn. Safety, comfort, speeds, and other criteria may lead to different preferences and judgment as to how well the controlled trajectory has been computed. |

Particle filter to detect static and dynamic obstacles
Briefly, example methods, apparatuses, and/or articles of manufacture may be implemented to access, from at least one memory device, sensor measurements generated by one or more sensors mounted in a vehicle and to generate an occupancy grid having grid cells that track occupancy, by static obstacles and dynamic obstacles, in an environment of the vehicle based on the accessed sensor measurements. An apparatus may additionally allocate (i) a first set of particles to estimate occupancy of grid cells by the static obstacles and states of the static obstacles and (ii) a second set of particles to estimate occupancy of grid cells by the dynamic obstacles and states of the dynamic obstacles. An apparatus may additionally execute one or more operations to plan motion of the vehicle based on the estimated occupancy of grid cells by the static obstacles and dynamic obstacles. |
