Accurate single-shot quantitative phase imaging of biological specimens with telecentric digital holographic microscopy
2014
The advantages of using a telecentric imaging system in digital holographic microscopy (DHM) to study biological specimens are highlighted. To this end, the performances of nontelecentric DHM and telecentric DHM are evaluated from the quantitative phase imaging (QPI) point of view. The evaluated stability of the microscope allows single-shot QPI in DHM by using telecentric imaging systems. Quantitative phase maps of a section of the head of the drosophila melanogaster fly and of red blood cells are obtained via single-shot DHM with no numerical postprocessing. With these maps we show that the use of telecentric DHM provides larger field of view for a given magnification and permits more acc…
Debating Europe: Effects of the “Eurovision Debate” on EU Attitudes of Young German Voters and the Moderating Role Played by Political Involvement
2016
In the run-up to the elections to the European Parliament in 2014, EU citizens had the unprecedented opportunity to watch televised debates between the candidates running for president of the European Commission. The most important debate was the so-called "Eurovision debate", which was broadcasted in almost all EU member states. In this study we explore the responses of a sample of 110 young German voters, who watched this debate, to the candidates' messages and whether exposure to the debate caused a shift in the respondents' attitudes towards the EU. Combining data from a quasi-experiment, real-time response data, and data from a content analysis of the debate, we find that respondents' …
Not Worth the Net Worth? The Democratic Dilemmas of Privileged Access to Information
2017
In this article, we discuss the democratic conditions for parliamentary oversight in EU foreign affairs. Our point of departure is two Interinstitutional Agreements (IIAs) between the Council and the European Parliament (EP), which provide the latter with access to sensitive documents. To shed light on this issue, we ask to what extent these contribute to the democratic accountability in EU foreign policy? It is argued that the IIAs have strengthened the EP’s role in EU foreign affairs by giving it access to information to which it was previously denied. This does not mean, however, that this increase in power equals a strengthening of the EP as a democratic accountability forum. First of a…
Mínguez, Víctor; Rodríguez Moya, Inmaculada. Napoleón y el espejo de la Antigüedad. Arqueología de las imágenes del poder
2015
En Napoleón y el espejo de la Antigüedad, el Dr. Víctor Mínguez y la Dra. Inmaculada Rodríguez culminan una intensa labor investigadora iniciada con el proyecto I+D “Arqueología de las imágenes del poder. El arte imperial romano como modelo iconográfico en las Cortes Europeas desde el Renacimiento a Napoleón” (P1.1B2012-02), integrado en el Plan de Investigación de la Universitat Jaume I y dirigido por el Dr. Víctor Mínguez. Encabezado por la presentación del prestigioso doctor Philippe Bordes, uno de los máximos especialistas en historia del arte de la Revolución francesa y de la época del Imperio, este ambicioso proyecto elabora un exhaustivo recorrido a través del estudio de los modelos …
Misericordia recuperada. Historia y arte de la antigua casa de la misericordia
2007
La Casa de la Misericordia de Valencia fue creada en 1670 por iniciativa del municipio, siguiendo el ejemplo de las ciudades de Barcelona y Zaragoza, donde en los años 1581 y 1669 respectivamente se habían creado casas de misericordia como albergue para quitar de la vida pública a tos pobres. A lo largo de su larga trayectoria, desde su fundación hasta su extinción en 1981. la institución benéfica pasó por tos más diversos avatares y tuvo dos sedes: la primera situada en la morería enfrente de la iglesia de San Miguel que alojó la institución hasta 1949, y la segunda situada en el barrio de Sosternes cerca del Hospital General; teniendo como sede provisional entre 1949 y finales de 1954, mi…
Integrating Domain Knowledge in Data-Driven Earth Observation With Process Convolutions
2022
The modelling of Earth observation data is a challenging problem, typically approached by either purely mechanistic or purely data-driven methods. Mechanistic models encode the domain knowledge and physical rules governing the system. Such models, however, need the correct specification of all interactions between variables in the problem and the appropriate parameterization is a challenge in itself. On the other hand, machine learning approaches are flexible data-driven tools, able to approximate arbitrarily complex functions, but lack interpretability and struggle when data is scarce or in extrapolation regimes. In this paper, we argue that hybrid learning schemes that combine both approa…
The Lightfield Microscope Eyepiece
2021
Lightfield microscopy has raised growing interest in the last few years. Its ability to get three-dimensional information about the sample in a single shot makes it suitable for many applications in which time resolution is fundamental. In this paper we present a novel device, which is capable of converting any conventional microscope into a lightfield microscope. Based on the Fourier integral microscope concept, we designed the lightfield microscope eyepiece. This is coupled to the eyepiece port, to let the user exploit all the host microscope’s components (objective turret, illumination systems, translation stage, etc.) and get a 3D reconstruction of the sample. After the optical design, …
Laparoscopic endopelvic sacral implantation of a Brindley controller for recovery of bladder function in a paralyzed patient
2008
Background: A number of techniques are being investigated to accomplish bladder control recovery in paralyzed patients using the neurostimulation, but currently, all techniques are based on the dorsal implantation of the electrodes using a laminectomy. Methods: On 27 April 2006 we performed a laparoscopic implantation of a Finetech-Brindley bladder controller on the endopelvic sacral roots in a Th8 completely paralyzed woman who had previously undergone the removal of a Brindley controller due to an arachnoiditis after extrathecal implantation with intradural sacral deafferentation. Results: We required about 3.5 h for the entire surgical procedure; no complications occurred and the patient…
Exploring the spatial relationship between airborne-derived red and far-red sun-induced fluorescence and process-based GPP estimates in a forest ecos…
2019
International audience; Terrestrial gross primary productivity (GPP) plays an essential role in the global carbon cycle, but the quantification of the spatial and temporal variations in photosynthesis is still largely uncertain. Our work aimed to investigate the potential of remote sensing to provide new insights into plant photosynthesis at a fine spatial resolution. This goal was achieved by exploiting high-resolution images acquired with the FLuorescence EXplorer (FLEX) airborne demonstrator HyPlant. The sensor was flown over a mixed forest, and the images collected were elaborated to obtain two independent indicators of plant photosynthesis. First, maps of sun-induced chlorophyll fluore…
