Functional connectivity modulation induced by transcranial direct current stimulation of the motor network investigated by resting state fMRI
2015
This study is aimed at measuring the variation of functional connectivity between cortical brain regions after tDCS along time. For this purpose we enrolled 20 healthy right-handed subjects.

La “uberización” de los centros escolares: reorganización del trabajo pedagógico mediante las plataformas digitales de contenidos
2018
El presente trabajo se inscribe en el marco de un proyecto de investigación de I+D que estudia los cambios producidos en los centros de Primaria por la progresiva sustitución de los libros de texto por los materiales digitales. Uno de esos cambios observados es que los materiales digitales se hacen operativos mediante plataformas digitales que, además, se hacen extensibles a otras muchas tareas de centro. A partir de esta constatación nos ocupamos aquí del estudio de la 'uberización' o reestructuración organizativa del trabajo en los centros que operan con estas plataformas. Para alcanzar tal objetivo hemos recurrido a una metodología de corte cualitativo, tanto para el análisis de la prese…
Design & Optimization of Large Cylindrical Radomes with Subcell and Non-Orthogonal FDTD Meshes Combined with Genetic Algorithms
2021
The word radome is a contraction of radar and dome. The function of radomes is to protect antennas from atmospheric agents. Radomes are closed structures that protect the antennas from environmental factors such as wind, rain, ice, sand, and ultraviolet rays, among others. The radomes are passive structures that introduce return losses, and whose proper design would relax the requirement of complex front-end elements such as amplifiers. The radome consists mostly in a thin dielectric curved shape cover and sometimes needs to be tuned using metal inserts to cancel the capacitive performance of the dielectric. Radomes are in the near field region of the antennas and a full wave analysis of th…
A New Approach to the Modeling of Anisotropic Media with the Transmission Line Matrix Method
2021
A reformulation of the Transmission Line Matrix (TLM) method is presented to model non-dispersive anisotropic media. Two TLM-based solutions to solve this problem can already be found in the literature, each one with an interesting feature. One can be considered a more conceptual approach, close to the TLM fundamentals, which identifies each TLM in Maxwell’s equations with a specific line. But this simplicity is achieved at the expense of an increase in the memory storage requirements of a general situation. The second existing solution is a more powerful and general formulation that avoids this increase in memory storage. However, it is based on signal processing techniques and considerabl…
Is There a Predisposition towards the Use of New Technologies within the Traffic Field of Emerging Countries? The Case of the Dominican Republic
2021
Technological devices are becoming more and more integrated in the management and control of traffic in big cities. The population perceives the benefits provided by these systems, and, therefore, citizens usually have a favorable opinion of them. However, emerging countries, which have fewer available infrastructures, could present a certain lack of trust. The objective of this work is to detect the level of knowledge and predisposition towards the use of new technologies in the transportation field of the Dominican Republic. For this study, the National Survey on Mobility was administered to a sample of Dominican citizens, proportional to the ONE census and to sex, age and province. The k…
Cytokine Polymorphism in Takotsubo Cardiomyopathy

Novo1 1University of Palermo, Palermo, Italy Background: Takotsubo (TT) cardiomyopathy is characterised by an acute left ventricular dysfunction triggered by emotional or physical stresses. Clinically, the syndrome is characterised by acute symptoms mimicking acute infarction without relevant electrocardiographic and biochemical markers of myocardial damage changes. Stressful events inducing an excess catecholamine release and myocardial β-adrenergic receptors (β-AR) seem to play a major role in TT. Ac…
