Abstract: Provided are an interaction method and apparatus in a live streaming room, a device, and a storage medium. The method comprises: in response to a trigger operation for a preset drawing entry on a live streaming room page, jumping to a graphic drawing page from the live streaming room page, a drawing trajectory set for a preset object being displayed on the graphical drawing page; when a drawing stroke on the graphic drawing page is received, matching the drawing stroke with the drawing trajectory; and if it is determined that the drawing stroke is successfully matched with the drawing trajectory, displaying prompt information about successful participation in a preset activity, the preset activity and the preset drawing entry having a correspondence.

Abstract: The present disclosure provides a live-stream interaction method, a live-stream interaction system and related devices. The system includes a terminal of an audience, a terminal of an anchor, and a server; the terminal of the audience is configured to present a live-stream interface, and the live-stream interface includes an interaction control that supports interaction, and when the audience triggers an interactive behavior through the interaction control, an interaction image when the audience performs the interactive behavior is acquired; the terminal of the anchor is configured to send the behavior feature of the anchor to the server; the server is configured to acquire the behavior feature of the audience, match the behavior feature of the audience with the behavior feature of the anchor to obtain a matching result, and send a special effect instruction to the terminal of the audience according to the matching result.

Abstract: Disclosed is a method fir measuring a deviation angle of a fatigue microcrack based on nonlinear ultrasound, comprising: preliminarily positioning a fatigue microcrack to obtain a center of the microcrack; selecting a horizontal positive direction, and defining an orientation angle; drawing a positive circumference on a surface of a metal plate, and selecting a fixed interval angle; placing an excitation sensor and a receiving sensor on the drawn positive circumference according to the orientation angle; ultrasonically testing each group of ultrasonic sensing paths, and recording time domain waveform signals formed by each group of ultrasonic sensing paths; converting each group of time domain waveform signals into a corresponding frequency domain graph, extracting an ultrasonic fundamental wave signal amplitude and a second harmonic waveform amplitude, and calculating a relative nonlinear coefficient; drawing an orientation angle-relative nonlinear coefficient polar coordinate graph; and determining a deviat

Abstract: The present invention provides a TPBG antibody, a preparation method thereof, conjugates and use thereof. The TPBG antibody comprises one or more of the heavy chain CDR1, the heavy chain CDR2 and the heavy chain CDR3 of the heavy chain variable region of TPBG antibody, and/or one or more of the light chain CDR1, the light chain CDR2 and the light chain CDR3 of the light chain variable region of TPBG antibody, and the amino acid sequences of which are described in the present invention. The TPBG antibody is humanized antibody with high affinity, and the conjugates prepared by coupling the TPBG antibody with the small-molecule drug toxin MMAF can have a cytotoxicity effects on TPBG-positive cells, therefore the TPBG antibody can be used in the preparation of drugs for treating tumors and the like.
