Compounds for fluorescence sensing of duplex formation
Herein reported are new tricyclic cytidine compounds, such as 8-diethylamino-tC (8-DEA-tC), that respond to DNA and/or RNA duplex formation with up to a 20-fold increase in fluorescent quantum yield as compared with the free nucleoside, depending on neighboring bases. This turn-on response to duplex formation is by far the greatest of any reported nucleoside analogue that can participate in Watson-Crick base pairing. Measurements of the quantum yield of 8-DEA-tC mispaired with adenosine and, separately, opposite an abasic site show that there is almost no fluorescence increase without the formation of correct Watson-Crick hydrogen bonds. Kinetic isotope effects from the use of deuterated buffer show that the duplex protects 8-DEA-tC against quenching by excited state proton transfer. DFT calculations provide a rationale for the observed photophysical properties that is dependent on duplex integrity and the electronic structure of the analogue. |

Regulating device and method for regulating the steering angle of a vehicle
A regulating device for regulating the steering angle of a vehicle includes a first controller unit having at least one integrating component and configured to receive a control difference between first steering angle information, which is deduced from nominal steering angle information, and an actual steering angle. The first controller unit provides actuation information for a motor operating the steering. A compensation control circuit superposed on the first controller unit is provided. The compensation control circuit has a feedback path receives actuation information of the motor, the output torque of the motor, and/or information dependent on the output torque of the motor as the input variable and, based on the input variable, provides steering angle compensation information. |

Systems and methods for automatic air and electrical connections on autonomous cargo vehicles
The technology relates to autonomous vehicles having hitched or towed trailers for transporting cargo and other items between locations. Aspects of the technology provide a smart hitch connection between the fifth-wheel of a tractor unit and the kingpin of a trailer. This avoids requiring a person to make physical pneumatic and electrical connections between the fifth-wheel and kingpin using external hoses and cables. Instead, the necessary connections are made internally, autonomously. For instance, the fifth-wheel may provide air pressure via one or more slots arranged on a connection surface, and the trailer is configured to receive the air pressure through one or more openings on a contact surface of the kingpin. An electrical connection section of the fifth-wheel may also provide electrical signals and/or power to an electrical contact interface of the kingpin. Rotational information about relative alignment of the trailer to the tractor unit may also be provided. |

Steering device
A steering device according to one embodiment includes: an input device including an input shaft to which rotation associated with operation is transmitted, and a transmission shaft that is disposed orthogonal to the input shaft and rotates in conjunction with the input shaft; a reducer receiving a rotational drive force from the input device and outputting a rotational force about a rotational axis with a reduced rotational speed and an increased torque; a motor providing a rotational auxiliary force to the reducer in a direction that augments the rotational driving force; and an output arm coupled to the reducer and rotating about the rotational axis in a predetermined angular range by the rotational force outputted by the reducer. The input device is disposed on one side of the reducer. The motor is disposed adjacent to a direction orthogonal to the transmission shaft and on the one side of the reducer. |

System and method for adjusting an air deflector
A system and method for adjusting an air deflector on a roof of a truck cabin to an optimal position when the truck is connected to a trailer, where the system comprises an air deflector, an electric actuator, and an electronic control unit, where the system further comprises a handheld device provided with stored information of different truck types and a table for different truck-trailer combinations, where the handheld device is adapted to determine a value corresponding to the height of the trailer and a value corresponding to the distance between the truck and the trailer, to determine a set value for the actuator based on the values and the stored information, and to send the set value to the electronic control unit, where the electronic control unit is adapted to set the air deflector in an optimal position by adjusting the actuator in dependency of the set value. |
