Publication number: 20240082285Abstract: The present invention discloses an application of chebulinic acid in preparation of anti-rotavirus drugs, which belongs to the technical field of anti-rotavirus drugs. Chebulinic acid has the effect of resisting rotavirus biosynthesis, has no effect of resistance to rotavirus adsorption and direct killing, and can inhibit the gene expression of VP6 to play an anti-RV role. Network pharmacology analysis indicates that chebulinic acid acts on rotavirus-related genes. Compared with the prior art, the present invention has the beneficial effects that: the present invention relates to an application of chebulinic acid in preparation of anti-rotavirus drugs.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Lijun Song, Wenchang Zhao, Yupei Qian, Yuxuan Feng, Yujing Zhou

Patent number: 10940845Abstract: The present invention discloses a motor-magnetostrictive actuator hybrid brake-by-wire system. The system includes a motor, a transmission mechanism, a magnetostrictive-driving piston mechanism and a floating-caliper disc mechanism. The transmission mechanism includes a planetary gear set and a screw set, and is driven by the motor. The linear motion of the sleeve is achieved by the planetary gear set and screw set. The sleeve pushes forward the piston head of the magnetostrictive-driving piston mechanism and the piston head pushes forward the brake pad back plate of the floating-caliper disc mechanism to clamp the brake disc, which accomplishes braking.Type: GrantFiled: July 20, 2017Date of Patent: March 9, 2021Assignee: HEFEI UNIVERSITY OF TECHNOLOGYInventors: Xianxu Bai, Yang Li, Feilong Cai, Zhiyuan Si, Lijun Qian

Patent number: 9904536Abstract: In an embodiment, a method is performed by a computer system. The method includes determining a scope of widget discovery in a content-management system. The method further includes automatically identifying widget instances of the content-management system that are within the determined scope of widget discovery. In addition, the method includes discovering attributes of the identified widget instances on a per widget-instance basis. The method also includes storing in memory widget-instance relationship data comprising the determined attributes of the identified widget instances. Moreover, the method includes receiving a multi-widget-instance change definition, wherein the multi-widget-instance change definition articulates a specified change to unspecified widget instances which share a specified widget-instance attribute.Type: GrantFiled: September 18, 2015Date of Patent: February 27, 2018Assignee: Quest Software Inc.Inventors: Lijun Qian, Guoxiong Wu, Mary Cindy Ah Kioon, Michel Albert Brisebois

Patent number: 9843651Abstract: In one embodiment, a method includes, responsive to a trigger, automatically discovering localization value sets that are maintained at a plurality of application servers which execute a particular software application such that each localization value set comprises language-specific key-value pairs for user-interface display items of the particular software application and such that the discovering yields an overall collection of localization value sets. The method further includes determining a localization value set of the overall collection that is not stored at the computer system. In addition, the method includes storing the determined localization value set at the computer system.Type: GrantFiled: December 21, 2015Date of Patent: December 12, 2017Assignee: Dell Software Inc.Inventors: Guoxiong Wu, Mary Cindy Ah Kioon, Lijun Qian

Patent number: 7298719Abstract: A new approach is described for scheduling uplink or downlink transmissions in a network having remote terminals communicating with a central hub. The scheduler keeps track of a token count. The token count for a given remote terminal is incremented by a target amount in each pertinent timeslot, but is also decremented each time that the remote terminal is served. The amount of the decrement for one timeslot is the amount of data served, i.e., transmitted to or from the remote terminal, in that timeslot. In exemplary embodiments of the invention, the target amount by which T is incremented depends on the current value of T. Whenever the token count is non-negative (i.e., whenever it has a positive or zero value), the target amount is a desired floor, or lower limit, on an average amount of data delivered to or from the given remote terminal in one timeslot. Whenever the token count is negative, the target amount is a desired ceiling, or upper limit, on the same average amount of data delivered.Type: GrantFiled: April 15, 2002Date of Patent: November 20, 2007Assignee: Lucent Technologies Inc.Inventors: Daniel Matthew Andrews, Lijun Qian, Aleksandr Stolyar

Patent number: 7158804Abstract: Mobiles are sorted by using a first metric and one or more of the sorted mobiles are selected. A second metric is determined using the selected sorted mobiles, and mobiles are selected to transmit during a time period based on the second metric. Multiple embodiments are disclosed using these steps and exact or approximate solutions as to which mobiles should transmit may be determined. By way of example, the first metric may be a weighted marginal rate and the second metric may be an objective function. An uplink proportional fair technique is presented in which, for example, either a single “strong” mobile or a group of “weak” mobiles may be selected to transmit during a single time period. In addition, techniques are presented for determining uplink scheduling when there is partial orthogonality in Walsh codes, modeled by an orthogonality factor, assigned to mobiles.Type: GrantFiled: November 27, 2002Date of Patent: January 2, 2007Assignee: Lucent Technologies Inc.Inventors: Krishnan Kumaran, Lijun Qian

Publication number: 20050239489Abstract: The present invention relates to a method and system for closed loop power control in a mobile communication system. Error is determined between a target signal-to-interference (SIR) and a received SIR. A power control scheme at a power controller of a base station determines a power change that is proportional to the error. Gain of the power controller is selected to achieve minimum error at a subsequent time instant.Type: ApplicationFiled: February 11, 2005Publication date: October 27, 2005Inventors: Lijun Qian, Zoran Gajic
