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: This application relates to communication methods and apparatuses. In an example method, a first communication apparatus generates first indication information, and sends the first indication information to a second communication apparatus. The first indication information indicates M orbital angular momentum (OAM) modes jointly supported by the first communication apparatus and the second communication apparatus, where there is a correspondence between N OAM modes in the M OAM modes and a demodulation reference signal (DMRS) port.

Abstract: A power converter comprising a first capacitor, a flyback conversion module, a soft-start module, and a feedback control module. The flyback conversion module is coupled with the first capacitor and configured to receive a first control voltage across the first capacitor. The soft-start module is coupled with the first capacitor and is configured to charge the first capacitor during a startup stage, to increase the first control voltage to an expected voltage value at the end of the startup stage. The feedback control module is coupled with the flyback conversion module and is configured to control the flyback conversion module to output a substantially constant voltage or current after the startup stage. Wherein the expected voltage value is a value of the first control voltage when the flyback conversion module outputs a substantially constant voltage or current after the startup stage.

Abstract: Aspects of the present disclosure include a dimming device comprising a dimming signal interface module which includes an optical coupling module and an analog-digital converter module having its input terminal connected to the input terminal of the dimming signal interface module and its output terminal selectively connected to the optical coupling module. The dimming signal interface module may receive digital signals and analog signals. When the analog signals are received by the input terminal of the dimming signal interface module, the analog-digital converter module may convert the analog signals to square-wave signals and output the square-wave signals to the optical coupling module. When digital signals are received by the input terminal of the dimming signal interface module, the output terminal of the analog-digital converter module may be disconnected from the optical coupling module. The dimming device may be able to receive digital and analog control signals to be used for dimming.

Abstract: A lamp driving module for a gas-discharge lamp includes a lamp ballast module, and a lamp power control module coupled to the lamp ballast module. The lamp power control module is configured to drive the lamp in a DC mode during a run-up state and in an AC mode when not in the run-up state. The lamp power control module is configured to heat the amalgam in the lamp more quickly, accelerate migration of the released mercury vapor throughout the lamp discharge tube, and allow the lamp to get brighter faster.
