Mild cognitive impairment (MCI), a condition that often predates Alzheimer's disease (AD), can be remotely detected through a self-administered virtual reality brain training game. Thessaloniki, Greece, February 23, 2017 - Greek researchers demonstrated the potential of a self-administered virtual supermarket cognitive training game for remotely detecting mild cognitive impairment (MCI), without the need for an examiner, among a sample of older adults. MCI patients suffer from cognitive problems and often encounter difficulties in performing complex activities such as financial planning. They are at a high risk for progressing to dementia however early detection of MCI and suitable interventions can stabilize the patients' condition and prevent further decline. It has been shown that virtual reality game-based applications and especially virtual supermarkets can detect MCI. Past studies have utilized user performance in such applications along with data from standardized neuropsychological tests in order to detect MCI. The team that conducted this study was the first scientific team to achieve reliable MCI detection using a virtual reality game-based application on its own. In that previous study , administration of the virtual super market (VSM) exercise was conducted by an examiner. The present study eliminated the need for an examiner by calculating the average performance of older adults using a special version of the VSM application, the VSM Remote Assessment Routine (VSM-RAR), at home on their own, for a period of one month. It is the first instance where a self-administered virtual reality application was used to detect MCI with a high degree of reliability. The research team included scientists from the Aristotle University of Thessaloniki (AUTH), the Centre for Research and Technology Hellas/Information Technologies Institute (CERTH/ITI), the Greek Association of Alzheimer's Disease and Related Disorders (GAADRD) and the Network Aging Research (NAR) of the University of Heidelberg. In an article published in the Journal of Alzheimer's Disease, the researchers have indicated that the virtual supermarket remote assessment routine (VSM-RAR) application displayed a correct classification rate (CCR) of 91.8% improving VSM's CCR as assessed in the previous VSM study while achieving a level of diagnostic accuracy similar to the most accurate standardized neuropsychological tests, which are considered the gold standard for MCI detection. Self-administered computerized cognitive training exercises/games are gaining popularity among older adults as an easy and enjoyable means of maintaining cognitive health. Such applications are especially popular among older adults who consider themselves healthy and are not inclined to visit specialized memory clinics for cognitive assessment. If self-administered games and exercises could also detect cognitive disorders, initial cognitive screening could be conducted remotely. The wide implementation of this method of remote screening would facilitate the detection of cognitive impairment at the MCI stage thus allowing for more efficient therapeutic interventions. This preliminary study indicates that automated, remote MCI screening is feasible. This method could be utilized to screen the majority of the older adult population, as it dramatically lowers examination-related costs. The social and economic benefits, especially caregiver and healthcare service burden, of the early detection of cognitive disorders could be enormous. At the same time, as older adults are becoming increasingly computer savvy, it is important to create software that meets their needs and allows them to remain healthy and active. Out team continues its research on the VSM with the aim of improving its usability, shortening its administration time and supplementing the science behind VSM with additional data.

MELBOURNE, Australia, Dec. 09, 2016 (GLOBE NEWSWIRE) -- Adherium Limited (ASX:ADR), a global leader in digital health technologies that address sub-optimal medication use in chronic disease, today announces that some of Europe’s most prestigious clinical opinion leaders have chosen Adherium’s Smartinhaler™ for the myAirCoach programme, part of the European Union’s Horizon 2020 Framework for Research and Innovation. The myAirCoach programme is being funded through the Horizon 2020 framework which is the largest EU Research and Innovation programme ever established with nearly €80 billion of funding available over 7 years (2014 to 2020). The purpose of the myAirCoach programme is to establish whether home monitoring and mobile health (mHealth) systems can be used to predict asthma control and the occurrence of asthma exacerbations. One of the main goals of the project is to help patients manage their health through user-friendly tools that will increase awareness of their clinical state as well as the adherence and effectiveness of the medical treatment they follow. The impact of the myAirCoach programme is expected to set the basis for the widespread adoption of sensor-based self-management systems across the spectrum of respiratory diseases. (Source: http://www.myaircoach.eu/myaircoach/content/what-myaircoach-project) Smartinhaler™ is already proven to reduce hospitalisation as demonstrated in the results of the year-long STAAR study, recently published online in the prestigious peer-reviewed medical journal Thorax . The study revealed a significant reduction in hospital admissions over the course of 12 months as well as substantial other health and quality of life benefits for patients using Smartinhaler™. The data from the STAAR study builds on a study published in January 2015 in The Lancet Respiratory Medicine  which showed the use of the Smartinhaler™ platform increased adherence to preventative medication by 180% and reduced use of reliever medication by 45%. “Successful disease management and prevention is only truly achieved by understanding the real-world complexity of our lives. The best way to do that is through rich data collected in the real world. By providing our innovative solutions to people with asthma, we can help people take the right medicine, at the right dose, at the right time and in the right way,” said Garth Sutherland, Founder & Group CEO of Adherium. “The myAirCoach programme is a leading initiative assessing the impact that digital health solutions, such as Smartinhaler™, can have on patients in a real-world setting. It is a major international project, funded by the prestigious European Union Horizon 2020 framework.” Participating organisations in the myAirCoach project include: Imperial College London, University of Manchester and Leiden University Medical Center. The project is anticipated to run for the next 12 months. Dr. Omar Usmani, Reader in Respiratory Medicine & Consultant Physician, National Heart and Lung Institute, Imperial College London and Royal Brompton Hospital, said; “The myAirCoach programme will help asthma sufferers to manage their health through user-friendly tools that will increase awareness of their clinical state as well as their adherence and the effectiveness of medical treatment they follow.” Professor Fan Chung, Professor of Respiratory Medicine and Head of Experimental Studies Medicine, National Heart and Lung Institute, Imperial College London and Royal Brompton Hospital, commented; “People with asthma are more likely to miss school or work and experience reduced quality of life. We are excited about the collaboration between Adherium and myAirCoach which is expected to set the basis for the widespread adoption of sensor-based self-management systems across the spectrum of respiratory diseases.” Adherium will be supplying a range of products to the programme via three key centres, including devices for inhaled medications manufactured by AstraZeneca and GSK: The project is coordinated by the Centre for Research and Technology Hellas (CERTH), Thessaloniki, Greece and is supported by a group of asthma patients acting as advisors. Other participating organisations in the myAirCoach project include: University of Patras, Allertec Hellas SA, IHP Microelectronics, ZorgGemak (MedVision 360BV), European Federation of Asthma & Allergy Associations, Cnet Svenska AB, Circassia and Asthma UK.

We place in the context of Information-Centric Networks a special class of segment-based caching, named partition-based caching, whereby information items are cached in partitions at different caches in the network. Our rationale lies in exploiting the merits of parallel data transmission, which however may come at the expense of increased network utilization. The study of this cost-benefit trade-off underlines our work. Following a theoretical analysis on the benefits of partition-based caching over single replication caching, we propose three traffic engineering algorithms for assigning content partitions to caches and respective routes. Simulation results indicate that partitionbased caching can indeed improve average content transfer time (up to 65%) at the expense of a tolerable increase in network load (up to 25%), for moderate numbers of content partitions (less than 6), balancing at the same time network load better (at the level of 50%), compared to single replication caching. © 2015 IEEE.

Frequent Episode Mining (FEM) techniques play an important role in data mining, and have multiple applications, spanning from identifying user marketing habits to performing anomaly detection in computer networks. Most of the FEM approaches exhaustively search for frequent patterns, while using a threshold to efficiently reduce the search space. While this approach provides efficient results in small datasets, it fails in large datasets due to heavy processing, which leads to low performance. This paper, proposes a fast frequent episode mining method which utilizes Finite-State Machines (FSM). Initially, a FSM is created based on a subset of the data, in order to approximate the type and frequency of the most dominant episodes. Instead of applying traditional exhaustive search procedures, the parsing of the dataset is herein guided by the proposed FSM approach. Experimental results show that the proposed approach has better time performance than the traditional FEM algorithms, while still maintaining high accuracy. © Springer International Publishing Switzerland 2016.

The objective of this paper is to provide an overview of the Synchronization of Multi-User Event Media (SEM) Task, which is part of the MediaEval Benchmark for Multimedia Evaluation. The SEM task was initially presented at MediaEval in 2014, with the goal of proposing a challenge in aligning multiple users' photo galleries related to the same event but with unreliable timestamps. Besides aligning the pictures on a common timeline, participants were also required to detect the sub-events and cluster the pictures accordingly. For 2015 we have decided to extend the task also to other types of media, thus including audio and video information for a more complete and diversified representation of the analyzed event.

The main promise of current research efforts in the area of Information-Centric Networking (ICN) architectures is to optimize the dissemination of information within transient communication relationships of endpoints. Efficient caching of information is key to delivering on this promise. In this paper, we look into achieving this promise from the angle of managed replication of information. Management decisions are made in order to efficiently place replicas of information in dedicated storage devices attached to nodes of the network. In contrast to traditional off-line external management systems we adopt a distributed autonomic management architecture where management intelligence is placed inside the network. Particularly, we present an autonomic cache management approach for ICNs, where distributed managers residing in cache-enabled nodes decide on which information items to cache. We propose four on-line intra-domain cache management algorithms with different level of autonomicity and compare them with respect to performance, complexity, execution time and message exchange overhead. Additionally, we derive a lower bound of the overall network traffic cost for a certain category of network topologies. Our extensive simulations, using realistic network topologies and synthetic workload generators, signify the importance of network wide knowledge and cooperation. © 2013 IEEE.
