Abstract: The present disclosure provides methods and systems for tracking a shipping vessel travel route through a retail enterprise during a stock cycle. Location information associated with assets can be collected at a retail location, from which a detailed route through the retail location may be recreated and overlaid on map data reflecting a retail location layout. Further analysis may be performed on the route. Additionally, the route may be overlaid on a map, including product information and packaging information, allowing for various metrics and metric visualizations to be generated that can be further analyzed to achieve various objectives.

Abstract: Provided are a sulfur-resistant and corrosion-resistant low-carbon alloy-based coiled tubing and a preparation method thereof. The sulfur-resistant and corrosion-resistant low-carbon alloy-based coiled tubing is prepared by subjecting a steel strip to butt welding, curling molding, tube blank welding, extrusion molding, weld heat treatment, and cooling in sequence, and the sulfur-resistant and corrosion-resistant low-carbon alloy-based coiled tubing includes the following components by mass percentage: 0.04% to 0.08% of C, 1.5% to 2.0% of Mn, 0.1% to 0.3% of Si, 0.1% to 0.3% of Cr, 0.05% to 0.3% of Mo, 0.04% to 0.07% of Nb, 0.005% to 0.025% of Ti, 0.01% to 0.05% of Al, not greater than 0.3% of Ni, not greater than 0.3% of Cu, not greater than 0.02% of P, not greater than 0.02% of S, and Fe and unavoidable impurities as a balance.

Abstract: Disclosed is technology for determining a wait time of objects in a designated area of a physical space. A system can include: cameras positioned proximate the designated area to capture image data of the designated area, location signaling devices to capture wireless signals indicating locations of the objects, the locations being provided as location data, and a computer system. The computer system can: receive the image data and the location data, translate the receive image data into a predetermined coordinate plane, retrieve one or more artificial intelligence (AI) models from a data store, identify the objects within the designated area based on applying the AI models to at least the translated image data, correlate the identified objects with the received location data, and determine wait time information of the identified objects in the designated area based on applying the AI models to at least the correlated data.

Abstract: Methods and compositions for modulating hydrogel gelation and mechanics for 3D cell culture are provided. Hydrogels have a variety of benefits for cell and tissue culture, including without limitation homogeneous distribution of materials and cells at the initiation of the 3D cell culture, disruption of network formation and disassociation of the 3D cell culture for cell retrieval, etc. The method for modulating the stiffness of a hydrogel solution comprises contacting a hydrogel solution with an effective amount of a competitor agent sufficient to modulate the stiffness of the hydrogel solution. In some embodiments, the methods further comprise contacting the hydrogel solution with a catalyst agent wherein the catalyst agent increases the forward and reverse reaction rate of reversible covalent bond formation that occurs in the hydrogel solution.

Abstract: Provided is a road-rail dual purpose quick disassembly and assembly type rail grinding maintenance robot, including a left robot grinding unit, a right robot grinding unit and quick unit connecting devices. The two robot grinding units are fixedly connected to the left and right sides of the quick unit connecting devices by the quick unit connecting devices so as to achieve quick assembly and disassembly of the robot. Each of the robot grinding units includes a robot grinding device, a rail walking device, road walking devices, a frame, a shell component and an electric control component. The robot grinding device is fixedly installed on the inner side of the upper part of the frame. The rail walking device and the road walking devices are fixedly installed at the bottom of the frame. The degree of intelligent and flexible of rail grinding operation can be significantly improved.
