Abstract: The present application provides a method for estimating abundance and distribution features of antibiotic resistance genes (ARGs) in surfacial sediments of lake and reservoir, including step 1 of obtaining an annual input total of nitrogen and phosphorus pollutants of each tributary flowing into the lake and reservoir; step 2 of constructing a linear regression equation between the abundance of each type of ARGs and the nitrogen and phosphorus discharge; and step 3 of calculating annual input total of nitrogen and phosphorus pollutants to be estimated for each geographical location of the lake and reservoir using inverse distance weighting interpolation analysis based on the annual input total of the nitrogen and phosphorus pollutants obtained in step 1, and substituting the calculated annual input total into the linear regression equation to estimate the abundance of each type of ARGs and analyze a distribution feature of the ARGs.

Abstract: A method and a system for pollutant identifying and early warning based on cluster analysis include steps of: installing multiple high-definition cameras on a river or a sluice dam, capturing pollutant images in front of the sluice dam at certain intervals, and transmitting the pollutant images captured by the high-definition cameras to a computer; reading the pollutant images transmitted to the computer; extracting a main pollutant color in the pollutant images through cluster analysis; calculating a difference between the main pollutant color and RGB data in a pollutant color gamut database, and setting an aberration threshold to identify the pollutant color; performing scale conversion with two sets of common point image pixel coordinates and actual plane coordinates to calculate a current pollutant area; and judging whether a polluted area exceeds a critical value according to a preset pollutant area threshold, thereby realizing early warning.

Abstract: The present application provides a time synchronization method and an electronic device. The method includes sending a clock synchronization signal and first real time clock (RTC) information separately; and the clock synchronization signal is configured to measure a delay between a first module and at least one second module, the delay is used for phase compensation performed on the clock synchronization signal received at the side of the at least one second module, and the clock synchronization signal after being subjected to the phase compensation is configured to trigger the at least one second module to update local second RTC information to the first RTC information.

Abstract: Techniques for allocating resources including receiving a first sub-stream of a data stream associated with a job and determining a dependency of a plurality of stages of the job. The techniques further include determining a metric for a second sub-stream of the data stream, where processing of the second sub-stream is completed and the metric indicates information associated with the processing of the second sub-stream. The techniques further include allocating resources for processing the first sub-stream based at least in part on the metric and the dependency.

Abstract: A sealed enclosure is disclosed. Sealed enclosure has a case configured to receive an arc-prone electrical component, a face frame defining an opening, a door configured to cover the opening, a sealing surface on the face frame or on the door, and one or more flaps having an sealing portion, the sealing portion being angled relative to the sealing surface, the one or more flaps being operational to flex from a disengaged position when not under pressure, to an engaged position in contact with the sealing surface when exposed to pressure inside the case during an arcing event. Sealed enclosure doors and methods of sealing an enclosure during an arcing event are also provided, as are other aspects.
