El error diagnóstico en radiología. Análisis de variables explicativas
2019
ANTECEDENTES: Se ha demostrado que la etiología del error médico es multifactorial, con convergencia de factores humanos activos (errores de percepción, cognición y/o comunicación) y factores latentes del sistema. Los factores latentes del sistema son aquellas variables que pueden predisponer a la aparición de errores activos, o aumentar el impacto negativo de estos. Incluyen una amplia variedad de elementos, entre otros el material de trabajo inadecuado, la sobrecarga de trabajo, la falta de experiencia del radiólogo, la información clínica insuficiente y la no disponibilidad de estudios previos. Nuestra hipótesis de trabajo es que los factores latentes contribuyen significativamente al er…
Securitización e inversiones extranjeras: control del riesgo de ciertas inversiones para la seguridad nacional del Estado
2019
El aumento constante de las inversiones extranjeras durante las últimas décadas ha venido acompañado de un cambio en sus parámetros. El origen de las inversiones varía, como lo hace su naturaleza y destino. La posibilidad de que sectores claves de la economía del Estado receptor acaben en manos de inversores extranjeros, en ocasiones pertenecientes o controlados por un Estado foráneo, es vista con prevención en muchos países y acentúa la creciente oposición al libre comercio y a la inversión extranjera. La limitada respuesta -ex post- ofrecida por el marco normativo internacional, lleva a los Estados a diseñar respuetas ex ante, dirigidas a controlar ciertas inversiones que por su origen, c…
Controllo contabile e controllo di costituzionalità delle leggi: una diversa prospettiva sul giudizio di costituzionalità in via incidentale

Norme perturbative degli equilibri economico-finanziari ed atipicità degli effetti delle decisioni di accoglimento? - 6. Le prospettive: il controllo sui costi dei diritti e sugli effetti delle sentenze. Some recent rulings of Italian Constitutional Court (Corte Cost. n…
Innovació en la manera d'avaluar de treballs en grup per motivar l'atenció dels alumnes
2014
En el nou escenari educatiu de l'Espai Europeu d'Educació Superior (EEES) cobra gran rellevància l'aprenentatge dels alumnes alhora que desenvolupen competències que els ajudin en el seu futur exercici professional. Entre aquestes habilitats es troben la capacitat de treball en equip i la capacitat d'exposar els resultats d'aquest treball d'una manera clara, concisa i rigorós. Per això el professor ha d'incentivar als alumnes a que es prenguin aquesta activitat amb la suficient motivació i fomentant la dedicació de la mateixa. Tradicionalment, l'exposició d'aquests treballs només interessava als propis membres del grup mentre que els seus companys veien aquesta activitat de forma passiva qu…
Crystal structure of (2E)-3-[4-(dimethylamino)phenyl]-1-(thiophen-2-yl)prop-2-en-1-one
2017
In the title chalcone-thiophene derivative, the dihedral angle between the aromatic and the thiophene rings is 11.4 (2)°. In the crystal, molecules are linked by C—H⋯O and C—H⋯S weak interactions along [100], forming rings of R22(8) graph-set motif, by C—H⋯O weak interactions along [010], forming C(6) chains, and by weak H(methyl–group)⋯Cg(thiophene ring) interactions into dimers; the crystal packing resembles a herringbone arrangement when viewed along [100]. A molecular docking calculation of the title compound with the neuraminidase enzyme was carried out.
Mapping daily evapotranspiration at field to global scales using geostationary and polar orbiting satellite imagery
2010
Abstract. Thermal infrared (TIR) remote sensing of land-surface temperature (LST) provides valuable information about the sub-surface moisture status required for estimating evapotranspiration (ET) and detecting the onset and severity of drought. While empirical indices measuring anomalies in LST and vegetation amount (e.g., as quantified by the Normalized Difference Vegetation Index; NDVI) have demonstrated utility in monitoring ET and drought conditions over large areas, they may provide ambiguous results when other factors (soil moisture, advection, air temperature) are affecting plant stress. A more physically based interpretation of LST and NDVI and their relationship to sub-surface mo…
Communication-Efficient Federated Learning in Channel Constrained Internet of Things
2022
Federated learning (FL) is able to utilize the computing capability and maintain the privacy of the end devices by collecting and aggregating the locally trained learning model parameters while keeping the local personal data. As the most widely-used FL framework,Jederated averaging (FedAvg) suffers an expensive communication cost especially when there are large amounts of devices involving the FL process. Moreover, when considering asynchronous FL, the slowest device becomes the bottleneck for the cask effect and determines the overall latency. In this work, we propose a communication-efficient federated learning framework with partial model aggregation (CE-FedPA) algorithm to utilize comp…
Monitoring Water and Energy Cycles at Climate Scale in the Third Pole Environment (CLIMATE-TPE)
2021
A better understanding of the water and energy cycles at climate scale in the Third Pole Environment is essential for assessing and understanding the causes of changes in the cryosphere and hydrosphere in relation to changes of plateau atmosphere in the Asian monsoon system and for predicting the possible changes in water resources in South and East Asia. This paper reports the following results: (1) A platform of in situ observation stations is briefly described for quantifying the interactions in hydrosphere-pedosphere-atmosphere-cryosphere-biosphere over the Tibetan Plateau. (2) A multiyear in situ L-Band microwave radiometry of land surface processes is used to develop a new microwave r…
