DevOps for network function virtualisation: an architectural approach
The Service Programming and Orchestration for Virtualised Software Networks (SONATA) project targets both the flexible programmability of software networks and the optimisation of their deployments by means of integrating Development and Operations in order to accelerate industry adoption of software networks and reduce time-to-market for networked services. SONATA supports network function chaining and orchestration, making service platforms modular and easier to customise to the needs of different service providers, and introduces a specialised Development and Operations model for supporting developers

The Effects of a Point Loss Contingency on Equivalence
The effects of point loss for symmetrical probe performances on other performances of an observed equivalence class, on the emergence of equivalence performances, and on performances in other contexts were examined. After training six conditional discriminations in three contexts, probes (symmetry, transitivity, symmetrical transitivity) were introduced in contexts 1 and 2. In context 3, only trained conditional discrimination trials were delivered. After demonstrations of equivalence in contexts 1 and 2, point loss was placed on symmetrical performances in one of these contexts; probe trials and point loss for symmetrical performances were simultaneously introduced in context 3. Point loss for symmetrical performances may disrupt other probe performances of an observed equivalence class in that same context; does not necessarily disrupt the emergence of equivalence performances; and may disrupt probe performances in other contexts
A novel method for transcatheter closure of atrial septal defect within an aneurysm of the fossa ovalis: double sheath technique
An aneurysm of the fossa ovalis is frequently associated with an atrial septal defect. Intervention with transcatheter closure of such defects may be difficult since it bears the risk of inadvertent deployment of the device with both umbrellas in the right or left atrium. A novel technique for the closure of such multiperforated aneurysms of the fossa ovalis, which allows central positioning and controlled deployment of the device, is reported.
