Ética del discurso: ¿un marco filosófico para la neuroética?

2013

Neuroethics requires a framework of philosophical ethics from which to interprete, integrate and criticiseneuroscientific progress in moral field. This article sets out to: 1) Show to what extent this framework is necessary; 2) Tackle the question of the method for constructing this framework; 3) Compile the main tópoi of the neurosciences that the framework has to interpret and integrate; 4) Propose the ethics of discourse as a philosophical framework for neuroethics; 5) Display certain shortcomings of this framework and put forward the dialogical ethics of cordial reason as being more appropriate.La Neuroética necesita un marco de ética filosófica desde el que interpretar, integrar y crit…

Optimization of Delayed-State Kalman-Filter-based Algorithm via Differential Evolution for Sensorless Control of Induction Motors

2010

This paper proposes the employment of the differential evolution (DE) to offline optimize the covariance matrices of a new reduced delayed-state Kalman-filter (DSKF)-based algorithm which estimates the stator-flux linkage components, in the stationary reference frame, to realize sensorless control of induction motors (IMs). The DSKF-based algorithm uses the derivatives of the stator-flux components as mathematical model and the stator-voltage equations as observation model so that only a vector of four variables has to be offline optimized. Numerical results, carried out using a low-speed training test, show that the proposed DE-based approach is very promising and clearly outperforms a cla…

Les exercices gradués dans la méthode du Grammalessico francese a uso degl’italiani d’Arminio Wurmbrand Bianchi

2020

L’article se propose d’analyser les exercices du manuel d’Arminio Wurmbrand Bianchi, Grammalessico francese a uso degl’italiani, qui ont une forme et une structure que l’on retrouve dans de nombreux manuels s’inspirant des méthodes dites « synthétiques ». Wurmbrand, en effet, introduit dans son manuel une nouveauté pour pourvoir au caractère incomplet de la méthode synthétique : il propose, ainsi, avant chaque exercice, la traduction des seuls termes « radicalement dissemblables » des deux langues « similaires à l’origine » qui caractérisent la langue française et la langue italienne. Le but est de fournir aux élèves la maîtrise lexicale de la langue française avec une attention toute parti…

Shape evolution in even-even N≤126, Z≥82 nuclei

2010

The shape evolution in the neutron-de cient lead, polonium and radium nuclei has been investigated via in-beam and delayed y-ray and conversion electron spectroscopy. The lead isotope 180Pb is found to still exhibit prolate excited structure, related to the known intruder structures in the heavier isotopes. The production cross-section of 180Pb was only 10 nb, one of the lowest ever employed in an in-beam experiment. A candidate for an excited prolate band was found in 192Po, making it the rst polonium isotope for which both oblate and prolate rotational bands have been established. Contrary to the previous results, the current experiments indicate that the onset of deformation in the radiu…

Biomechanical analysis of Ascending Thoracic Aortic Aneurysm (ATAA)

2021

According to the reports of the World Health Organisation (WHO), cardiovascular diseases are the number one cause of death worldwide. Specifically, arterial disease and degeneration are the major reasons for cardiovascular death and disability. Because these diseases are dependent on the changes of the mechanical properties of the arterial wall, it is very important to know as much as possible about the structural composition of arteries. The human aorta is the biggest artery in the body and consists of three main parts, ascending aorta, aortic arch and descending aorta. The walls of the arteries consist of three layers, the intima, media and adventitia, where each of the layers has differe…

Optically pumped Cs magnetometers enabling a high-sensitivity search for the neutron electric dipole moment

2020

An array of 16 laser-pumped scalar Cs magnetometers was part of the neutron electric dipole moment (nEDM) experiment taking data at the Paul Scherrer Institute in 2015 and 2016. It was deployed to measure the gradients of the experiment's magnetic field and to monitor their temporal evolution. The originality of the array lies in its compact design, in which a single near-infrared diode laser drives all magnetometers that are located in a high-vacuum chamber, with a selection of the sensors mounted on a high-voltage electrode. We describe details of the Cs sensors' construction and modes of operation, emphasizing the accuracy and sensitivity of the magnetic-field readout. We present two app…

First measurement of proton's charge form factor at very low $Q^2$ with initial state radiation

2017

We report on a new experimental method based on initial-state radiation (ISR) in e-p scattering, in which the radiative tail of the elastic e-p peak contains information on the proton charge form factor ($G_E^p$) at extremely small $Q^2$. The ISR technique was validated in a dedicated experiment using the spectrometers of the A1-Collaboration at the Mainz Microtron (MAMI). This provided first measurements of $G_E^p$ for $0.001\leq Q^2\leq 0.004 (GeV/c)^2$.

Normal pressures and frictional tractions on shallow conical hopper walls after concentric filling: Predictions and experiments

2013

Author's version of an article in the journal: Chemical Engineering Science. Also available from the publisher at: http://dx.doi.org/10.1016/j.ces.2012.11.028 A silo with a shallow hopper is designed to achieve the required silo capacity when the headroom available is limited, provided that the issue of segregation of stored particulate solids is not a problem. Several analytical models have been proposed to try to predict the design loads for such shallow silo hoppers to guarantee their structural integrity. In this study, a novel finite element analysis has been conducted to explore the development of pressures and tractions on the wall of a full scale shallow hopper when it is filled wit…
