Publication number: 20200331910Abstract: Disclosed are compounds that are shown to inhibit the biological activity of nitric oxide synthases (NOSs). Also disclosed are pharmaceutical compositions comprising the compounds, and methods of using the compounds and pharmaceutical compositions for treating a subject in need thereof. Because the disclosed compounds are shown to inhibit the activity of nitric oxide synthases (NOSs), the disclosed compounds and pharmaceutical compositions may be utilized in methods for treating a subject having or at risk for developing a disease or disorder that is associated with NOS activity.Type: ApplicationFiled: June 26, 2020Publication date: October 22, 2020Inventors: Richard B.

Patent number: 8351349Abstract: In Universal Network, there is disclosed a method and system for realizing location management of multihomed terminals, the system comprises home domains and foreign domains, in which the home domains of a multihomed terminal refer to the domains managing the multihomed terminal; the other domains are the foreign domains of the multihomed terminal; each domain includes at least one Identifier Mapping Server and one Accessing-Switching Router; the Identifier Mapping Server memorizes and manages the mapping information; and the Accessing-Switching Router allocates the mapping information for multihomed terminals. This invention facilitates the implement of multihoming in the Internet and makes the network resources be used efficiently. Especially, the Internet service providers can manage the multihomed terminals easily and efficiently.Type: GrantFiled: August 6, 2009Date of Patent: January 8, 2013Assignee: Beijing Jiaotong UniversityInventors: Ping Dong, Haisheng Jiang, Hongke Zhang, Dong Yang, Yajuan Qin, Xiaobo Liu, Feng Qiu

Patent number: 8068439Abstract: A method of Concurrent Multipath Transfer which is based on the relational paths, characterized in that for a packet lost in a path, it allows other packets sent from the path and/or other paths to point out the lost packet through a gap report. According to the present invention, any lost packets and abnormal paths can be found as fast as possible, and can be retransmitted quickly. So this method can avoid the failure of all paths from handing in packets to upper layer only for the abnormity in one path, which limits the speed of whole association.Type: GrantFiled: June 24, 2009Date of Patent: November 29, 2011Assignee: Beijing Jiaotong UniversityInventors: Hongke Zhang, Chang Liu, Dong Yang, Ping Dong, Yajuan Qin, Huan Yan, Liang Sun

Patent number: 8015603Abstract: A method for packet transmission in an MIP network is disclosed. A mobile node sends to a Home Agent (HA) a first Firewall Detection (FD) packet encapsulated with IP security (IPsec) protocol and a second FD packet encapsulated with the IPsec protocol and User Datagram Payload (UDP) protocol. The mobile node determines whether there is a firewall blocking an IPsec packet between the mobile node and the HA according to a Firewall Detection Reply (FDR) packet from the HA. If there is a firewall, packets are encapsulated with the UDP protocol and binding update and packet exchange are performed; otherwise, binding update and packet exchange are performed. A mobile node for packet transmission is also provided. Embodiments of the present invention enables the mobile node to exchange a packet with a correspondent node when there is a firewall not supporting the IPsec protocol between the mobile node and the HA.Type: GrantFiled: September 14, 2007Date of Patent: September 6, 2011Assignee: Huawei Technologies Co., Ltd.Inventors: Hongke Zhang, Sidong Zhang, Shen Yang, Wei Su, Yan Ren, Zuzhou Zheng, Yajuan Qin, Shuai Gao, Jianglin Wang, Ying Liu, Fuyou Miao

Publication number: 20080072279Abstract: A method for a MIPv6 packet traversing a firewall includes: acquiring filtering information containing the home address of a Mobile Node (MN) from an MIPv6 packet initiating communication; establishing a filtering rule according to the filtering information; and filtering a sequent MIPv6 packet according to the filtering rule. A firewall according to the above method is also provided. According to the present invention, it may be guaranteed that a MIPv6 pack may reliably traverse a firewall in various cases. Moreover, in the case that an MN and a CN do not know whether there is a firewall between them and do not know the location of the firewall, the normal communication may still ensure not to be interrupted when the address of the MN changes.Type: ApplicationFiled: September 19, 2007Publication date: March 20, 2008Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Fuyou MIAO, Hongke ZHANG, Sidong ZHANG, Shen YANG, Wei SU, Yan REN, Zuzhou ZHENG, Yajuan QIN, Shuai GAO, Jianglin WANG, Ying LIU
