    Augmented EHR: Enrichment of EHR with Contents from Semantic Web Sources

    [EN] This work presents methods to combine data from the Semantic Web into existing EHRs, leading to an augmented EHR. An existing EHR extract is augmented by combining it with additional information from external sources, typically linked data sources. The starting point is a standardized EHR extract described by an archetype. The method consists of combining specific data from the original EHR with contents from the external information source by building a semantic representation, which is used to query the external source. The results are converted into a standardized EHR extract according to an archetype. This work sets the foundations to transform Semantic Web contents into normalized EHR extracts. Finally, to exemplify the approach, the work includes a practical use case in which the summarized EHR is augmented with drug¿drug interactions and disease-related treatment information.This work has been supported by the Spanish Ministry of Economy and Competitiveness and the FEDER program through grant TIN2014-53749-C2-1-R, and by the Spanish Ministry of Science, Innovation and Universities through grant PTQ2018-009924.Mañas-García, A.; Maldonado, JA.; Marcos, M.; Boscá, D.; Robles, M.

    Electrical model for characterizing CVD graphene

    Full text link
    Due to its extremely small thickness (0.35 nm), graphene is an intrinsic 2D nanomaterial. As in many other nanomaterials, its unique properties are derived from its exceptional dimensions. One of these properties is its linear dispersion equation that implies charge carriers with extraordinary high mobility. Therefore, the electronic properties of the material can lead to a big improvement in the performance of known electronic devices, or even result in novel devices for a post-silicon era

    Method for electrical evaluation of graphene using a GFET structure

    n this work, we explain a method to characterize graphene using electrical measurements in graphene field-effect transistors (GFET) devices. Our goal is to obtain the material electronic properties from the output characteristics of one GFET device. For the previous purpose, we will need to apply a physical model that allows us to correlate the electronic behavior of a GFET with the material properties

    Improve data management in two public hospitals in Paraguay - Hospital de Clínicas and Instituto Nacional del Cáncer (INCAN). Currently, data management in oncology department is complex and requires advanced Information System to process data where "omic" information should be integrated together with patient's clinical data to improve data analysis and decision-making process. Conceptual Modelling is an important and essential activity that helps us not only to design an abstract model of an advanced Information System but also facilitates the development process.CONACYT - Consejo Nacional de Ciencias y TecnologíaPROCIENCI

    Detailed Clinical Models Governance System in a Regional EHR Project

    Full text link
    The final publication is available at Springer via http://dx.doi.org/ 10.1007/978-3-319-00846-2_313In this work we present the Concept Oriented Repository (ROC), a system developed for the management of clinical information models, also known as detailed clinical models (DCM). It has been developed to be used in the Electronic Health Record project of the Valencia regional health agency (AVS). The system uses DCMs as a way to define clinical models independently of the healthcare standard chosen by the organization. These definitions create a framework where different actors can come to agreements on which information has to be represented and managed in the project. These concepts can be used later for the definition of technical artifacts (archetypes, templates, forms or message definitions) to be used by AVS information systemsThis work has been funded by Electronic Health History project from Valencia Health Agency (HSEAVS).Boscá Tomás, D.; Marco Ruiz, L.; Moner Cano, D.; Maldonado Segura, JA.; Insa, L.; Robles Viejo, M.

    Graphene for energy storage

    Full text link
    Due to its excellent mechanical, termal, optical and electrical properties, graphene has recently attracted increasing attention. It provides a huge surface area (2630m2 g-1) and high electrical conductivity, making it an attractive material for applications in energy-storage systems

    Dynamic local strain in graphene generated by surface acoustic waves

    Full text link
    We experimentally demonstrate that the Raman active optical phonon modes of single layer graphene can be modulated by the dynamic local strain created by surface acoustic waves (SAWs). In particular, the dynamic strain field of the SAW is shown to induce a Raman scattering intensity variation as large as 15% and a phonon frequency shift of up to 10 cm1^{-1} for the G band, for instance, for an effective hydrostatic strain of 0.24% generated in a single layer graphene atop a LiNbO3_{3} piezoelectric substrate with a SAW resonator operating at a frequency of \sim 400 MHz. Thus, we demonstrate that SAWs are powerful tools to modulate the optical and vibrational properties of supported graphene by means of the high-frequency localized deformations tailored by the acoustic transducers, which can also be extended to other 2D systems.Comment: 10 pages, 7 figure

    Polyaniline-coated carbon papers for supercapacitor electrodes

    Full text link
    Graphene and carbon nanotubes are promising materials for supercapacitor electrodes because of their high specific surface area and excellent electrical, thermal, and mechanical properties. However, these materials suffer from a high manufacturing cost and some aggregation of graphene layers or the presence of toxic residual metallic impurities of carbon nanotubes
