    A laparoscopic approach to cesarean scar ectopic pregnancy
    (Elsevier, 2021) Pickett, Charlotte M.; Minalt, Nicole; Higgins, Olivia M.; Bernard, Caitlin; Kasper, Kelly M.; Obstetrics and Gynecology, School of Medicine
    Cesarean scar pregnancies confer serious risk and severe morbidity. Appropriate management is the key to preventing complications. Although expectant management is usually contraindicated, the ideal combination of medical or surgical treatments is unclear and must be tailored to the patient’s preferences and stability, provider skill, and the available resources. In this article, we present a combined medical and surgical approach that was successfully employed for the termination and excision of a cesarean scar pregnancy at 12 weeks’ gestation in a patient desiring uterine preservation. A video is included, demonstrating the surgical steps of a laparoscopic approach used to safely resect the pregnancy and cesarean delivery scar with minimal blood loss. The management technique described can be utilized to effectively resolve cesarean scar pregnancy, to possibly decrease the risk of recurrence, and preserve future fertility with a minimally invasive outpatient surgery.

    Video over Software-Defined Networking (VSDN)
    (Elsevier, 2015-12) Owens, Harold II; Durresi, Arjan; Department of Computer and Information Science, School of Science
    Supporting end-to-end quality of service (QoS) for real-time interactive video applications, such as video conferencing and distance learning, requires the network to select an optimum path from among multiple paths. Multiple network paths may be available between the source and the destination, but finding an alternative path is difficult because of the high coupling and complex design of the network. Network architectures such as Integrated Services (IntServ) install the path selected by the routing protocol, which may not deliver best-case performance. Furthermore, it is an arduous task for the video application developer to request service from IntServ. We provide three contributions to the literature on providing end-to-end QoS for real-time interactive video applications. First, we present Video over Software-Defined Networking (VSDN), a network architecture that selects the optimum path using a network-wide view. Second, we describe the VSDN protocol that is used by the developer to request QoS from the network. Finally, we present the results of implementing a VSDN prototype and evaluate the behavior of VSDN using message complexity, network throughput, network delay, and network jitter. The message complexity of VSDN is linear.
