Abstract: A hot bed deformation tolerance structure for a large-sized continuous fiber high-temperature 3D printer is provided. Size changes caused by thermal expansion of a hot bed are compensated through motion coordination of a secured hot bed support assembly and a motion device, especially for an aluminum alloy material. A Z-direction motion structure of this structure is fixedly mounted with a frame and works at room temperature. A compensation motion module is fixedly mounted with a Z axis and incompletely secured with the hot bed support assembly, and works at room temperature with the Z axis. The hot bed support assembly is incompletely secured and partially in a high-temperature chamber, with a maximum working temperature of 300° C. The hot bed support assembly retains motion redundancy in a direction of thermal expansion deformation, tolerates thermal deformation through a linear motion module, and compensates for metal deformation through horizontal motion coordination.

Abstract: The present disclosure provides the use of BAZ1B_K426hy in the preparation of a product for tumor detection and belongs to the field of biotechnology. The present disclosure further provides a group of immunogenic polypeptides, including polypeptide A and polypeptide B. An anti-BAZ1B_K426hy polyclonal antibody is prepared by conducting mixed immunization on an animal with the immunogenic polypeptide. The polyclonal antibody can specifically recognize an endogenous protein BAZ1B_K426hy by enzyme-linked immunosorbent assay (ELISA)/Dot blot/Western blot, which is used for preparation of detection products for tumors and Williams syndrome.

Abstract: In some examples, a system includes a memory configured to store a database comprising a map of a plurality of runways in an aerodrome and a receiver configured to receive a clearance for a vehicle from a traffic control system. The system also includes processing circuitry determine that the vehicle is active on a first runway of the plurality of runways based on a state vector for the vehicle and based on the map of the plurality of runways. The processing circuitry is also configured to determine that the vehicle is active on a second runway of the plurality of runways based on the received clearance. The processing circuitry is further configured to confirm whether the first runway matches the second runway and present, via a display, an indication that the vehicle is active on the first runway in response to confirming that the first runway matches the second runway.

Abstract: In some examples, a system includes a receiver configured to receive a signal and processing circuitry configured to determine a velocity vector of the ownship vehicle and determine a position of a target vehicle relative to the ownship vehicle based on the signal, determine a velocity vector of the target vehicle relative to the ownship vehicle based on the signal and the velocity vector of the ownship vehicle, and determine a characteristic of a graphical vector icon of the velocity vector of the target vehicle based on a display range of a graphical user interface. The processing circuitry is also configured to present, via a display, the graphical user interface including a first graphical icon corresponding to the ownship vehicle, a second graphical icon corresponding to the target vehicle based on the position of the target vehicle relative to the ownship vehicle, and the graphical vector icon with the characteristic.
