Abstract: Provided are an interaction method and apparatus in a live streaming room, and a device and a storage medium. The method comprises: in response to a trigger operation for a preset duet entry on a live streaming room page, jumping from the live streaming room page to a camera capture page, wherein a host portrait cutout corresponding to the live streaming room page is displayed on the camera capture page and a capture control is provided on the camera capture page acquiring multimedia information captured by a camera, in response to a trigger operation for the capture control on the camera capture page, wherein the multimedia information comprises an image or a video; and synthesizing the multimedia information with the host portrait cutout to obtain a duet multimedia product.

Abstract: A quantitative source apportionment method based on nontarget high-resolution mass spectrometry (HRMS) data of pollution sources and pollution receptors includes: acquiring samples of pollution sources and receptors, pre-processing samples to extract trace organic pollutants; acquiring chromatography-HRMS nontarget data; pre-processing raw data to obtain a HRMS dataset including a mass-to-charge ratio, a retention time, and a peak area; determining a source-sink relationship based on positions of pollution sources and receptors; constructing an input matrix by combining the HRMS dataset and using each sink as a group; adopting an expectation-maximization method or a Bayesian method to calculate contribution of each source based on a standardized input matrix. Beneficial effects at least include the follows.

Abstract: The present disclosure provides a method and apparatus for ingesting data, a device, a storage medium and a program product, and particularly to the field of computer technology, the field of intelligent traffic, and the like. A specific implementation comprises: deploying a first data ingestion system at a first data source, the first data ingestion system comprising a first read plugin, a first transmission plugin and a first write plugin; reading data from the first data source through the first read plugin; writing the data into a first transmission buffer queue through the first transmission plugin; and acquiring the data from the first transmission buffer queue through the first write plugin and writing the data into a first storage component. The data ingestion system in the present disclosure is divided into a read part, a transmission part and a write part. Each part works by means of a plugin.
