Abstract: The present disclosure relates to a degradation method of a perfluoroalkyl substance (PFAS). The degradation method includes the following steps: polymerizing indole to synthesize pind; and mixing synthesized pind with the PFAS to form a mixed solution, and illuminating the formed mixed solution to allow pind to generate hydrated electrons (eaq?) for degrading the PFAS. In the degradation method of the present disclosure, indole with a high yield of hydrated electrons is polymerized to generate pind, and pind is used as a precursor for the generation of the hydrated electrons to increase the stability of a molecular structure of pind through a highly conjugated structure formed after polymerization, thereby achieving the purpose of continuously generating the hydrated electrons under ultraviolet irradiation and effectively degrading PFASs, which is of great significance for addressing the environmental pollution problem of PFASs.

Abstract: The invention presents an LED display device featuring a highly efficient installation method. It consists of display screens arranged in a matrix, with adjacent screens connected via a rapid assembly. This assembly includes a motor screw structure affixed to one screen and a nut structure fixed to the adjacent screen. The motor screw structure incorporates a deceleration motor and a screw fixed on the screen, while the nut structure comprises a nut fixed on the screen via a mounting plate. During assembly, power is applied only after alignment, allowing the deceleration motor to rotate the screw. The nut then adjusts the distance between screens until installation requirements are met, enhancing installation efficiency.

Abstract: Disclosed is a method for improving transverse magnetic (TM) mode light extraction efficiency of an ultraviolet AlInGaN light-emitting diode. As the Al content in the AlInGaN light-emitting diode increases, the wavelength decreases gradually. Meanwhile, light extraction dominated by a TE mode is switched to light extraction dominated by a TM mode. To improve the light extraction efficiency of the TM mode, in the present disclosure, a passivation layer is first grown in an etched N-type electrode region and an edge electrode region, and then a reflective metal region of an inverted trapezoidal structure is etched in the region of the passivation layer. Metal with high reflectivity for ultraviolet light is evaporated in the region of the inverted trapezoidal structure, and TM light generated in a quantum well can be reflected to the external through a metal layer with high reflectivity, which improves the TM mode light extraction efficiency.

Abstract: This document describes techniques, systems, and methods for multi-scan sensor fusion for object tracking. A sensor-fusion system can obtain radar tracks and vision tracks generated for an environment of a vehicle. The sensor-fusion system maintains sets of hypotheses for associations between the vision tracks and the radar tracks based on multiple scans of radar data and vision data. The set of hypotheses include mass values for the associations. The sensor-fusion system determines a probability value for each hypothesis. Based on the probability value, matches between radar tracks and vision tracks are determined. The sensor-fusion system then outputs the matches to a semi-autonomous or autonomous driving system to control operation of the vehicle. In this way, the described techniques, systems, and methods can provide high-precision object tracking with quantifiable uncertainty.
