An eHealth-Care Driven Perspective on 5G Networks and Infrastructure

This work describes the advancements that next generation mobile networks can bring to emergency services on the basis of a fully 5G enabled medical emergency response scenario. An ambulance service combining autonomous driving, advanced on-board patient monitoring, remote diagnosis and remote control from the hospital is introduced, allowing increased levels of care during patient transport and improved early diagnosis, thus enhancing patient survival rates. Furthermore, it is shown that such an ambulance service requires a variety of different traffic types that can only be supported concurrently and with guaranteed quality of service by a high-performance network fulfilling all 5G key performance indicators. The scenario described combines a multitude of aspects and applications enabled by 5G mobile communications, including autonomous driving, ultra-high definition video streaming, tactile remote interaction and continuous sensing, into a compelling showcase for a 5G enabled future. A centralized radio access 5G network with space division multiplexed optical fronthaul using analog radio-over-fiber and optical beamforming is analyzed, fully supporting SDN and NFV for advanced network slicing and quality of service guarantee.</p

The next challenge for world wide robotized tele-echography experiment (WORTEX 2012): from engineering success to healthcare delivery.

Access to good quality healthcare remains difficult for many patients whether they live in developed or developing countries. In developed countries, specialist medical expertise is concentrated in major hospitals in urban settings both to improve clinical outcomes and as a strategy to reduce the costs of specialist healthcare delivery. In developing countries, millions of people have limited, if any, routine access to a healthcare system and due to economic and cultural factors the accessibility of any services may be restricted. In both cases, geographical, socio-political, cultural and economic factors produce ‘medically isolated areas’ where patients find themselves disadvantaged in terms of timely diagnosis and expert and/or expensive treatment. The robotized teleechography approach, also referred to as robotized teleultrasound, offers a potential solution to diagnostic imaging in medically isolated areas. It is designed for patients requiring ultrasound scans for routine care (e.g., ante natal care) and for diagnostic imaging to investigate acute and medical emergencies conditions, including trauma care and responses to natural disasters such as earthquakes. The robotized teleechography system can hold any standard ultrasound probe; this lightweight system is positioned on the patient’s body by a healthcare assistant. The medical expert, a clinician with expertise in ultrasound imaging and diagnosis, is in a distant location and, using a dedicated joystick, remotely controls the scanning via any available communication link (Internet, satellite). The WORTEX2012 intercontinental trials of the system conducted last year successfully demonstrated the feasibility of remote robotized tele-echography in a range of cultural, technical and clinical contexts. In addition to the engineering success, these trials provided positive feedback from the participating clinicians and patients on using the system and on the system’s perceived potential to transform healthcare in medically isolated areas. The next challenge is to show evidence that this innovative technology can deliver on its promise if introduced into routine healthcare

The Deep‐water corals of Cyprus: Environmental settings and ecological features (CYprus Cold‐corals Levantine SeA, Eastern MEditerraneaN: CYCLAMEN)

The recently started research project CYCLAMEN (CYprus Cold-corals Levantine SeA, Eastern MEditerraneaN), will conduct the first detailed study of cold-water coral communities in eastern Cypriot waters. Cold-water coral habitats have been found during exploratory surveys. The 2-yr long project will include the environmental characterization of the area, as well as the study of the spatial distribution of cold-water coral communities. In addition to the study of the biology of the coral species, genetic and eco-physiological studies will be included. This project is the first of its kind in Cyprus and will additionally have an associated scientific outreach programme in order to bring these ecosystems, still poorly known, to the general public. The project is led by the Spanish Institute of Oceanography (IEO), and relies on the participation of research Institutions in Cyprus: The Cyprus Institute (CyI) and the NGO Enalia Physis Environmental Research Centre (EPERC); France: Aix-Marseille University – Mediterranean Institute for Biodiversity & Ecology (AMU-IMBE); Greece: The Hellenic Centre for Marine Research (HCMR); Mónaco: Centre Scientifique de Monaco (CSM); United Kingdom: National Oceanography Centre (NOC), and Spain: Universitat de Barcelona (UB). Here we present the conceptual frame of the project, the background knowledge and the first obtained results in the oceanographic cruise carried out in summer 2015

Interplay between elastic instabilities and shear-banding: three categories of Taylor–Couette flows and beyond

In the past twenty years, shear-banding flows have been probed by various techniques, such as rheometry, velocimetry and flow birefringence. In micellar solutions, many of the data collected exhibit unexplained spatiotemporal fluctuations. Recently, it has been suggested that those fluctuations originate from a purely elastic instability of the shear-banding flow. In cylindrical Couette geometry, the instability is reminiscent of the Taylor-like instability observed in viscoelastic polymer solutions. The criterion for purely elastic Taylor–Couette instability adapted to shear-banding flows suggested three categories of shear-banding depending on their stability. In the present study, we report on a large set of experimental data which demonstrates the existence of the three categories of shear-banding flows in various surfactant solutions. Consistent with theoretical predictions, increases in the surfactant concentration or in the curvature of the geometry destabilize the flow, whereas an increase in temperature stabilizes the flow. However, experiments also exhibit some interesting behaviors going beyond the purely elastic instability criterion.National Science Foundation (U.S.). Graduate Research Fellowship Progra

Robotic Systems for general Surgery, Regulatory approvals and Market potential

In general surgery there exists a tendency towards less invasive procedures. With the use of laparoscopy, patients’ scarring and hospitalization periods have been considerably reduced. Furthermore, computer and robotics technologies have introduced novelties that enhance the surgeons’ skills to accomplish high precision during the complex surgery process. Robotic surgery became reality before the end of last century. Key developments include the Aesop voice-controlled camera-holding device and the Zeus robotic system, both by Computer Motion. A leading role has also been played by the company Intuitive Surgical, that developed the Da Vinci Surgical Robot. A master-slave system architecture was used in relation to both abovementioned robotic systems, where the surgeon is located at a console at the side of the operating table and controls the surgical instruments. The two companies merged in 2003 and the resulting Da Vinci Surgical Robot dominated the market. Other remarkable surgical robots have also been developed for applications including orthopedic surgery, stereotactic brain surgery and urological interventions. In United States, the development, testing and evaluation of any medical robotic device is controlled by the Food and Drug Administration (FDA). In Europe apply similar regulatory requirements but they are not identical and products are often required to comply with both. This study briefly describes the FDA regulatory approval process and discusses the current status of the medical robotic systems market, as well as the future trends. Some of the most important medical robotic systems that have been approved for clinical use are briefly described to show the current status and the potential of the medical robotics technology

AN ONLINE 3D DATABASE SYSTEM FOR ENDANGERED ARCHITECTURAL AND ARCHAEOLOGICAL HERITAGE IN THE SOUTH-EASTERN MEDITERRANEAN

The World Heritage Convention, drawn by various international bodies in 1972, was designed to protect cultural or natural places of outstanding universal value so that future generations may be able to enjoy them. Responding to these principles as well as to the Charter on the Preservation of Digital heritage (Vancouver, 2003), this multidisciplinary project, which involves archaeologists, art historians, conservators and computer scientists, aims to create an open access, 3D interactive online geo-database of endangered architectural and archaeological heritage in the South Eastern Mediterranean basin; a region of tremendous cultural importance whose rech heritage is unfortunately threatened by both natural and human factors. A wide range of 3D modelling and topographic techniques have been applied to create accurate reconstructions of heritage sites, enriched by a extensive array of metadata
