Abstract: An article including: (a) a substrate (i) including a first primary surface and a second primary surface facing generally away from the first primary surface and (ii) exhibiting a substrate index of refraction; (b) a first layer of a high reflectance ink (i) layered over the second primary surface of the substrate, and (ii) exhibiting an ink index of refraction that is greater than the substrate index of refraction; and (c) a second layer of a substantially opaque ink, the second layer layered over the first layer, with the first layer sandwiched between the second layer and the substrate. The first layer is substantially free of a metallic component. For electromagnetic radiation throughout an entirety of the visible spectrum initially transmitted through the first primary surface of the substrate and incident on the first layer, the article exhibits an average reflectance that is greater than or equal to 4%.

Abstract: Provided is a one-component aqueous spray adhesive. The spray adhesive includes an aqueous chloroprene dispersion, where the increase of the Shore A hardness of the formed adhesive film in 0 to 10 hours accounts for equal to or more than 90% of the increase of the Shore A hardness of the formed adhesive film in 0 to 1000 hours; a styrene-acrylate copolymer dispersion having a solid content of 15% by weight to 25% by weight, relative to the total weight of solids of the aqueous chloroprene dispersion; a polyol ester without hydroxyl groups in an amount of 0.9% by weight to 3.8% by weight, relative to the total weight of the aqueous spray adhesive; and an amino acid in an amount of 4% by weight to 15% by weight, relative to the total weight of the aqueous chloroprene dispersion.

Abstract: A method for analyzing a correlation between rail transit and direct current (DC) magnetic bias of a transformer includes the steps of, A: obtaining a current of a feed cable and a DC magnetic bias current: measuring the feed cable current in rail transit and the DC magnetic bias current of a transformer in a power grid within a certain period by a monitoring apparatus; B: calculating a characteristic quantity of the feed current within the measurement period based on the obtained current of the feed cable; C: calculating a characteristic quantity of the DC magnetic bias current within the measurement period based on the DC magnetic bias current; and D: calculating a support degree and a confidence coefficient based on the calculated characteristic quantity of the feed current and the calculated characteristic quantity of the DC magnetic bias current, and generating a correlation rule.

Abstract: Weigh-in-motion sensors comprise a beam including a plate with a load-bearing surface, and a tube portion including a base wall and a cover and defining a cavity therebetween. A sensing package is disposed within the cavity and is under pre-load with the cover and the base wall. The sensing package comprises a piezoelectric element. The base wall includes an aperture extending from a mounting surface to the cavity. The aperture includes a fastener therein to secure the sensing package within the cavity. The fastener is sized having a cross-section dimension taken through a center axis of the fastener that is greater than that of a cross-section dimension of the piezoelectric element taken along the fastener center axis. In an example, the fastener has a cross-section dimension sized about 10 percent or greater in dimension than that of the respective cross-section dimension of the piezoelectric element.

Abstract: An embodiment method includes obtaining information about a serving node and information about a coordinating node of an edge user, performing coordinated scheduling on the edge user according to the information about the serving node and the information about the coordinating node, determining whether the serving node and the coordinating node can simultaneously schedule the edge user. In response to a determination that the serving node and the coordinating node can simultaneously schedule the edge user, the method further includes instructing the serving node and the coordinating node to allocate a same code channel resource to send data to the edge user.
