High Performance 3D PET Reconstruction Using Spherical Basis Functions on a Polar Grid
2011
Statistical iterative methods are a widely used method of image reconstruction in emission tomography. Traditionally, the image space is modelled as a combination of cubic voxels as a matter of simplicity. After reconstruction, images are routinely filtered to reduce statistical noise at the cost of spatial resolution degradation. An alternative to produce lower noise during reconstruction is to model the image space with spherical basis functions. These basis functions overlap in space producing a significantly large number of non-zero elements in the system response matrix (SRM) to store, which additionally leads to long reconstruction times. These two problems are partly overcome by expl…
The factorization method for electrical impedance tomography data from a new planar device.
2006
We present numerical results for two reconstruction methods for a new planar electrical impedance tomography device. This prototype allows noninvasive medical imaging techniques if only one side of a patient is accessible for electric measurements. The two reconstruction methods have different properties: one is a linearization-type method that allows quantitative reconstructions; the other one, that is, the factorization method, is a qualitative one, and is designed to detect anomalies within the body.
Virtual Hierapolis: tra tecnicismo e realismo
2011
[ES] Una de las principales actividades de la MAIER tiene como objetivo desarrollar una línea de investigación dirigida a la restauración virtual y la reproducción 3D de los antiguos monumentos de la ciudad romana de Hierápolis de Frigia, Turquía. El proyecto, llamado "Virtual Hierápolis, se ha desarrollado gradualmente en las últimas tres temporadas de excavación (años 2007-2009) y ha madurado a partir de las primeras experiencias de la RV aplicada a este sitio en años anteriores. Esta investigación, coordinada por el Director de la misión italiana, prof. F. D'Andria, y llevada a cabo en el Laboratorio de Tecnologías de la Información (ITLab) dell'IBAM-CNR de Lecce (Italia), implica unidad…
Now you see me: perception as a basic principle in foreign languages learning
2016
No observamos todo lo que somos capaces de ver, ni escuchamos todo lo que creemos oír. Percibimos, en gran medida, aquello que estamos esperando que suceda y no lo que realmente sucede, hacemos reconstrucciones y predicciones constantemente. Así funciona el cerebro. En el caso de estudiantes cuya lengua materna es similar al español el principio de cierre hace que sean capaces de entender el sentido general del texto sin tan siquiera tener mucha práctica con el español. Por otro lado, este proceso puede suponer un impedimento a la hora de discriminar las diferencias que existen entre ambas lenguas. Buena prueba de ellos son aquellos que a pesar de vivir años en un ambiente de inmersión ling…

The relation between human values and perceived situation characteristics in everyday life
2018
Values refer to abstract beliefs which serve as guidelines in peoples’ life and affect the way people and events are evaluated. Simultaneously, unlike attitudes, values transcend specific actions, and situations. While recent research showed that values are related to the attention and interpretation of situational information in standardized laboratory settings, up to date hardly any empirical work investigated how values relate to situation perception in daily life. In our study, we assessed the relation between the endorsement of human values and situation characteristics (i.e., the 8 DIAMONDS). Using the Day Reconstruction Method in two samples (German and US-American), we found that es…
Estudio piloto de la validez convergente de la adaptación española del Denison Organizational Culture Survey (A pilot study of the convergent validit…
2016
The Denison Organizational Culture Survey (DOCS) is one of the most used instruments in the study of organizational culture. The aim of this study was to evaluate the convergent validity of the Spanish version of the DOCS using the Organizational Culture Inventory (OCI) developed by Cooke and Lafferty. This instrument is the most widely used and researched tool in the field of organizational psychology. The convergent validity of these instruments was evaluated using Pearson’s correlation analysis. The sample comprised 344 members from different research groups of a Spanish university. A poor correlation was found between the DOCS and the aggressive-defensive culture dimension of the OCI. H…
Experiencia de implantación de un método docente constructivista en la enseñanza de la medicina legal: La libertad de prescripción como ejemplo
2009
Introducción. El método constructivista va implantándose lentamente en la formación médica. En este tipo de aprendizaje, es el alumno el que va a construir el conocimiento sobre las bases cognitivas que ya posee. El profesor que sigue este método no se limita a suministrar un conocimiento ya elaborado, sino que ha de dirigir al alumno en su proceso autónomo y activo de aprendizaje. La principal limitación es el tiempo necesario para llevarlo a cabo con éxito porque obviamente el alumno necesita una información previa y un tiempo de elaboración y procesamiento de esos datos para conseguir construir un aprendizaje duradero. En el texto que sigue se describe la experiencia de la aplicación del…
Acromion clavicular joint reconstruction with LArS ligament in acute dislocation
2019
Background: The acromion clavicular joint dislocations are common injuries of the shoulder. The severity is dependent upon the degree of ligamentous injury. Surgical treatment is typically performed in higher grade acromioclavicular separation with several static and dynamic operative procedures with or without primary ligament replacement. Methods: 47 patients with acute Rockwood type III, IV, and V injuries were treated surgically with LARS reconstruction. The success of technique was evaluated by radiographic outcomes for each patient at every follow-up visit (one,three, 12 months), while to assess pain reduction and clinical evaluation Visual Analogue scale score (VAS) and Constant-Murl…
IMPLANT-PROSTHETIC REHABILITATION OF UNIDENTARE EDENTATION – PRINCIPLES OF TREATMENT
2015
For a practitioner with experience, the restoration with one or two individual crowns is relatively simple from clinical and technical point of view, but if a single crown has to be rebuilt in areas with major aesthetic concern, the prosthetic restoration becomes a challenge for any team of professionals. A major challenge for such a team si the unidental restoration, with or without implants, of a single incisor from the frontal maxillar area, especially the central superior incisors. These teeth have a highly aesthetic part since they are in direct connection with the shape and the aspect of the face. In the evaluation of the dental shape of the central incisors we can use different param…
