Abstract: A two-quaternary ammonium compound has a structural formula of formula (I). L1 is a C1 to C8 alkylene group; L2 is a C1 to C8 alkylene group; Z1 is nitro group or a halogen or methoxy group; Z2 is nitro group or a halogen or methoxy group; Z3 is nitro group or a halogen or methoxy group; R?H or a C1 to C6 alkyl group; a, b, and c are independently an integer from 0-5; and M is a pharmaceutically acceptable anion, such as a bromine ion, chlorine ion, sulfonate radical, etc. A stereoisomer or mixture of stereoisomers, or a pharmaceutically acceptable salt or solvate or eutectic of the compound of formula (I) forms a composition with a pharmaceutically acceptable carrier, or forms a compounded prescription with other active components, and the composition or compounded prescription may be used in the preparation of a muscle relaxant.

Abstract: A new scalable approach to conflict-free deployment of changes across networks. The conflict rules or constraints may be modeled using policies and algorithms to determine an optimized schedule for change deployment.

Abstract: A method includes receiving, at a model and optimization framework, a request, rendered in a first format, for a service to be implemented on a subset of a software-defined network. The request includes at least one constraint affecting implementation of the service. The method includes producing an optimized solution, rendered in a second format, for implementing the service based on the at least one constraint. The method includes translating the optimized solution to the first format and providing instructions for a cloud manager to implement the service consistent with the translated optimized solution.

Abstract: Concepts and technologies disclosed herein are directed to a multi-tier fault tolerant network design with Quality of Service (“QoS”) considerations. According to one aspect, a network planning system can identify at least one critical site of a plurality of sites. The critical site is considered to be critical for survivability of a network. The network planning system can construct a topology that connects the plurality of sites. The network planning system can determine a shortest path for each network link in the topology. The network planning system can check a service level agreement to determine a reliability requirement for each link in the topology that is not connected to the critical site. The network planning system can implement a reliable adaptive multipath provisioning algorithm to adaptively determine a bandwidth allocation on each link in the topology based, at least in part, upon the shortest path and the reliability requirement.

Abstract: Communication networks go through frequent upgrades, whereby access point (AP) devices that serve network client devices are brought offline to effectuate the upgrade. Concurrently upgrading too many AP devices within a given geographic area can lead to coverage holes where no service is available, congestion where data cannot be sufficiently communicated, or other service degradation. On the other hand, upgrading too few AP devices within the area can result in a network-wide upgrade time that is too great. An architecture is presented that can efficiently generate a schedule for upgrading AP devices of a communication network.
