Abstract: Disclosed are a phenyl amino sodium propionate derivative, a preparation method therefor and an application thereof. Specifically, disclosed are sodium 3-(4-(2-(9H-carbazole-9-yl)ethoxy)phenyl)-2-((2-(4-(4-(2-sodium forrnate-2-((2-(4-fluorobenzoyl)phenyl)amino)ethyl)phenoxy)benzoyl)phenyl)amino)propionate, a preparation method therefor and the use thereof for quality control of a bulk drug or formulation of Chiglitazar or a derivative thereof. Particularly, the compound can be used as a control substance or standard substance for the detection of impurities/related substances in Chiglitazar or a sodium salt drug thereof.

Abstract: An embodiment of the present application discloses a display panel, which includes a display area and a border area defined outside the display area, wherein a thin film transistor layer is disposed on a substrate; a light-emitting device corresponds to the display area and disposed on the thin film transistor layer; a support member corresponds to the border area, the support member is disposed on the substrate, and the support member is configurated to withstand external forces; and each of the support member includes at least one gradation portion, and in a thickness direction of the display panel, a width of the gradation portion has a gradation tendency.

Abstract: A system for automated dynamic compaction includes a compaction crane having a boom and compaction weight, at least one positional sensor, at least one boom deflection sensor, a rotational encoder, and a compaction control system. The compaction control system may be programmed to identify a first drop location having a first target parameter, determine whether the compaction crane is positioned over the first drop location, determine an initial elevation of the compaction weight, lift the compaction weight to a drop height, detect that the compaction weight has been released, re-hoist the compaction weight to the drop height, measure the payout length of a winch cable after each drop, determine a current elevation of the compaction weight after each drop, and determine whether the first target parameter has been satisfied.
