Publication number: 20240122200Abstract: Provided is a functional edible oil (FEO), a preparation method therefor and use thereof. The FEO is prepared by ternary transesterification of medium-chain triglycerides (MCTs), oils rich in linoleic acid, and oils rich in linolenic acid. The fatty acid composition and distribution of the FEO were determined and optimized via comparative analysis of indexes such as melting point, and effect of improving glucose and lipid metabolism as determined by animal tests. The FEO has a mass ratio of 2.3 to 4.0 for medium chain fatty acids (MCFAs) in MCTs to long chain fatty acids (LCFAs) in the oils rich in linoleic acid, and oils rich in linolenic acid and a mass ratio of 0.5 to 1.0 for linoleic acid to linolenic acid in the LCFAs, by mass of fatty acids. The FEO is added to food products at ?18.00%.Type: ApplicationFiled: October 14, 2021Publication date: April 18, 2024Inventors: Zheling ZENG, Guibing ZENG, Zhen OUYANG, Bo YANG, Ping YU, Jiaheng XIA, Maomao MA, Dongman WAN, Miao LUO, Cheng ZENG, Xuefang WEN

Publication number: 20240081360Abstract: Disclosed is a base oil for functional food oils and fats, a preparation method therefor and the use thereof. The base oil for functional food oils and fats is formed through ternary transesterification on medium-chain triglycerides, high-melting-point fat and oils rich in linolenic acid. The base oil for functional food oils and fats has a wide melting range, can significantly improve the glucose and lipid metabolism disorder, balance the essential and functional fatty acids in the body, and quickly replenish energy. Animal experiments were conducted and the fatty acid composition and distribution of the base oil were optimized and determined through comparative analysis based on evaluation indicators such as the improved effect in glucose and lipid metabolism and melting point.Type: ApplicationFiled: December 31, 2021Publication date: March 14, 2024Applicant: Nanchang UniversityInventors: Zheling Zeng, Guibing Zeng, Zhen Ouyang, Bo Yang, Ping Yu, Jiaheng Xia, Maomao Ma, Dongman Wan, Miao Luo, Cheng Zeng, Xuefang Wen

Publication number: 20220386136Abstract: Facilitating analysis and resource planning for advanced heterogeneous networks (e.g., 5G, 6G, and beyond) is provided herein. A system is provided that includes a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can include determining that a resource is to be added to existing resources at a grid level of a heterogeneous network. Further, the operations can include selecting candidate locations for placement of the resource based on a coverage-driven objective and a capacity-driven objective defined for the heterogeneous network. The coverage-driven objective can be associated with a demand for services within the grid level of the heterogeneous network. The capacity-driven objective can be associated with demand growth within the grid level of the heterogeneous network. The resource can be a fifth generation millimeter wave node or a cloud radio access network node.Type: ApplicationFiled: August 3, 2022Publication date: December 1, 2022Inventors: Jie Chen, Yuning Yang, Zhen Wan, Wenjie Zhao

Publication number: 20220103271Abstract: Architectures and techniques are presented that can provide point-to-point analysis to generate an improved signal strength prediction (SSP) based on, e.g., earth surface image data processing and analysis to draw conclusions of line of sight (LOS) along the propagation path between a BTS or another AP transmitter and CPE receiver. For example, USGS image data and/or elevation data of locations are identified to correspond to signal propagation between the transmitter and receiver can be analyzed for LOS signal quality at a fixed location, in addition to the statistical model prediction of the RF signal quality. As a result, foliage or terrain that obstructs the LOS can be identified and utilized to improve SSP by eliminating the additional pathloss due to LOS obstructions. Such can provide a significant improvement to SSP results that are conventionally predicted by statistical models rather than a point-to-point analysis.Type: ApplicationFiled: December 13, 2021Publication date: March 31, 2022Inventors: Zhen Wan, Xiaoyu Wang, Ravi Raina, Eric Antonio Alino, Zhefeng Li

Patent number: 10798537Abstract: A speed tier based pricing scheme is utilized to increase average revenue per user (ARPU) for fixed wireless applications. To offer a speed tier based pricing scheme, a radio environment at a location of Customer Premise Equipment (CPE) and/or data associated with cell sites serving the location can be analyzed to estimate a maximum data rate that can be delivered to the user CPE with a high confidence. Based on the estimated data rate, one or more speed tiers that can be offered to the customer for subscription. Further, based on an analysis of observed network usage and/or traffic demand per customer location with reference to the speed-tier classes subscribed to by existing customers, the network can efficiently plan for on-boarding new customers and/or network expansion.Type: GrantFiled: July 9, 2018Date of Patent: October 6, 2020Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Tony Wah-Tung Wong, Zhen Wan, Jyothis John, Ravi Raina
