Abstract: A baby stroller capable of implementing free switching between a single seat and double seats, includes a stroller body, wherein a retractable chassis is provided at the bottom of the stroller body, a retractable upper enclosure is mounted at a middle portion of the stroller body, the retractable upper enclosure comprises a fixed rod and a telescopic rod, the fixed rod and the telescopic rod each are hollow in a U shape, universal wheels are mounted at the bottom of the retractable chassis, and the telescopic rod is slidably connected in the fixed rod. According to the present invention, areas of an upper enclosure and a chassis of the stroller are reduced at the same time by means of the upper enclosure of the retractable chassis, so as to implement the retraction of the stroller body, and freely switch between the single seat and the double seats.

Abstract: New methods and kits for treating diseases caused or exacerbated by overactivated EphA4 signaling are provided. The method includes administering to a subject in need thereof an effective amount of a small molecule compound inhibitor for EphA4 signaling. Also provided are methods for identifying additional compounds as therapeutic agents useful for treating conditions involving overly active EphA4 signaling.

Abstract: A method of pulsed eddy current (PEC) testing includes receiving metal loss output measurements. The metal loss output measurements are calculated based on eddy current response captured by a probe at a location on a pipe or tank, wherein one or more energized high voltage cables are located within the pipe or tank. The method further includes generating compensated metal loss output measurements to compensate for errors in the metal loss output measurements caused by the energized high voltage cables. The method further includes outputting the compensated metal loss output measurements as PEC test results.

Abstract: Disclosed is a method for preparing an easy-to-swallow composite gel based on high-pressure shear induction and belongs to the technical field of food processing. Marine products are used as raw materials. A cross-linking degree of thermally denatured proteins and a combination degree of functional oil are synchronously regulated, calculated and controlled by one-step of emulsion filling and protein cross-linking. A composite gel prepared has low strength, high water/oil retention rate and the properties of “soft” easy-to-swallow foods. The composite gel is enhanced in efficacy by nutrition regulation, and the prepared easy-to-swallow composite gel achieves precise nutrition regulation. The composite gel is differently shaped by 3D printing according to different people's needs to improve consumers' appetite for easy-to-swallow foods.

Abstract: Disclosed are applications of humic acid (HA) in improving phytoremediation efficiency of heavy metals in waterbody, relating to the technical field of environmental ecological engineering. The phytoremediation of heavy metals is achieved by reducing heavy metals content in the waterbody by planting Vallisneria natans. HA is added to slow down the degreening of Vallisneria natans leaves under heavy metal toxicity, and to increase the accumulation of leaves and roots of Vallisneria natans to heavy metals, together with reducing the leaching capacity of heavy metals in waterbody; HA enhances the activity of enzymes related to reactive oxygen metabolism in plants by stimulating the synthesis of proteins and enzymes in various organs of plants, as well as reducing the concentration of malondialdehyde in plants, regulating the reactive oxygen content in plants, reducing the peroxidation of membrane lipids, and enhancing the resistance of plants to heavy metals.

Abstract: Provided is the discovery of the role of EphA4 signaling in neurodegenerative disorders involving ?-amyloid induced neurotoxicity such as Alzheimer's Disease. New therapeutic methods, therapeutic agents, and kits for treating diseases caused or exacerbated by overactivated EphA4 signaling are provided. Also provided are methods for identifying additional compounds as therapeutic agents useful for treating conditions involving overly active EphA4 signaling.
