With the massive growth of cutting-edge media services such as Ultra-High Definition (UHD/4K) video and immersive media (i.e. Virtual and Augmented Reality-VR/AR), demand for large investments in a scalable, ubiquitous, and robust communication infrastructure and services increases enormously. The H2020 5GCity project aims to provide a solution for such issues by designing, developing, and deploying a sliceable, distributed Cloud/Edge & radio platform with neutral hosting capability to support the sharing between Information Technology (IT) infrastructure owners and media service providers (i.e. vertical media actors). In this work, we initially introduce the essential benefits of the 5GCity technology and neutral host model to facilitate the rise of highly-demanding media Use Cases (UCs) and its implication on how service providers typically operate (in terms of business model). Then, we show how the 5GCity architecture and infrastructure, in light of certain Key Performance Indicators (KPIs), address this demand through three media UCs (namely related to "video acquisition and production at the edge", "immersive services", and "mobile production and transmission") and we explain how they are implemented and deployed in real citywide pilots (in Bristol, Lucca, and Barcelona) to demonstrate the benefits for infrastructure owners and media service providers*.

Large-diameter thick-walled steel pipes during their installation in deep-water are subjected to external pressure, which may trigger structural instability due to pipe ovalization, with detrimental effects. The resistance of offshore pipes against this instability is affected by local geometric deviations and residual stresses, introduced by the line pipe manufacturing process. In the present paper, the JCO-E pipe manufacturing process, a commonly adopted process for producing large-diameter pipes of significant thickness, is examined. The study examines the effect of JCO-E line pipe manufacturing process on the external pressure resistance of offshore pipes, candidates for deepwater applications using nonlinear finite element simulation tools. The cold bending induced by the JCO forming process as well as the subsequent welding and expansion (E) operations are simulated rigorously. Subsequently, the application of external pressure is modeled until structural instability (collapse) is detected. Both the JCO-E manufacturing process and the external pressure response of the pipe, are modeled using a two-dimensional (2D) generalized plane strain model, together with a coupled thermo-mechanical model for simulating the welding process.

A patient presented with a 6-month history of numbness and pain in the left forearm and hand over the ulnar nerve distribution. Radiographs showed a supracondylar process, which was excised. The ulnar nerve had been compressed. The patient was symptom-free two months postoperatively.

Introduction: The anatomical variations of bones in the hand are common. The existence of exostosis and shortening of metacarpal bones has been described in the literature as part of the hereditary multiple exostosis syndrome but no case has been reported with the co-existence of sesamoid ossicles in the same patient.
