In this work, we demonstrate how engineering the dielectric layer based on high-k polyvinylidene fluoride (PVDF)-based polymers can lead to a drastic reduction of device driving voltages and the improvement of its optoelectronic properties. We first investigated the morphology and the dielectric response of these polymer dielectrics in terms of polymer (P(VDF-TrFE) and P(VDF-TrFE-CFE)) and solvent content (cyclopentanone, methylethylketone). Implementing these high-k PVDF-based dielectrics enabled low-bias ambipolar organic light emitting transistors, with reduced threshold voltages (<20 V) and enhanced light output (compared to conventional polymer reference), along with an overall improvement of the device efficiency. Further, we preliminary transferred these fluorinated high-k dielectric films onto a plastic substrate to enable flexible light emitting transistors. These findings hold potential for broader exploitation of the OLET platform, where the device can now be driven by commercially available electronics, thus enabling flexible low-bias organic electronic devices.Peer reviewe
Adaptive Neural Network Imaging in Medical Systems
No full textRecent technological advances in medicine has facilitated the development of sophisticated equipment enabling the better delivery of health care services. In parallel, artificial neural networks have emerged as promising tools for the application and implementation of intelligent systems. The aim of this paper is to provide a snapshot of the application of neural network systems in medical imaging. The paper highlights neural network applications in the analysis of cervicovaginal smears, mammography, microscopy, ultrasound imaging, and lesion placement in pallidotomy. It is anticipated that the application of neural network systems in medicine will provide the framework for the development of emerging medical systems, enabling the better delivery of health care
C.S. Lewis: adaptations of life and work
No full textThe author discusses film representations of the life of C.S. Lewis – a famous English Christian writer. She also focuses on adaptations (that include books, television and cinema) of his most famous series The Chronicles of Narnia – series that for already sixty years have been published all over the world
Telematic requirements for emergency and disaster response derived from enterprise models
No full textOne of the prime objectives in disaster response management is to achieve full control of the situation as rapidly as possible. Coordination and communication facility therefore plays an essential role in managing disasters. This chapter discusses Enterprise Models that capture the invariant structures of medical emergency and disaster response management using notions like tasks, roles and agents. On one hand, these notions are generic enabling the model to cope with a broad range of events, from complex, dynamic and multifaceted disasters to more routine medical emergency cases. On the other hand, refinements of the models to specialized cases reveal the coordination and communication needs which are aligned with the context (i.e. the task objectives). This paves the way for dynamic selections of computing and network resource alternatives, possibly scarcely available on the scene, that match with the coordination and communication needs, for instance, hand-offs to a better communication alternative, possibly using a different wireless technology. The Enterprise models, which separate roles responsible for the tasks from the agents assigned to those roles, have the advantage that roles can be virtually moved to the scene of the disaster without the need to transport all agents to the scene. This latter is a simple form of an augmented reality environment, which brings on-site reality at the scene of the disaster into the scope of command and control of off-site teams or team members. A mobile telematic system is needed to bridge the coordination and communication spatial gap between roles or agents; its requirements however can be derived from the Enterprise models
The Nurse of Elfland: Lizzie Endicott and C.S. Lewis
No full textIn Surprised by Joy, C.S. Lewis introduced Lizzie Endicott as the first of two other blessings in his childhood, even before his introduction of Warnie. But apart from his abbreviated 136-word biography, very little is known about the nurse who introduced Lewis to faery tales. Based on the Lewis Family Papers, genealogical research, and personal interviews with Lizzie’s relatives, this article introduces Lizzie to the world of Lewismania. It also suggests various ways in which Lizzie influenced the man and the author that C.S. Lewis became, as well as the mythical worlds he created and Lewis’s anonymous tributes to her
Mobihealth: mobile services for health professionals
No full textThe concept behind the MobiHealth project (MobiHealth, 2002) was to bring together the technologies of Body Area Networks (BANs), wireless broadband communications and wearable devices to provide mobile healthcare services for patients and health professionals. For patients, these technologies enable remote patient care services such as management of chronic conditions and detection of health emergencies. For health professionals the technology offers access to information and communication services from a mobile device, thus enabling mobility for the individual professional and supporting the operation of distributed ‘virtual' healthcare teams (sensu Pitsillides, 1999)
