The human-computer connection: An overview of brain-computer interfaces
2018
This article introduces the field of brain-computer interfaces (BCI), which allows the control of devices without the generation of any active motor output but directly from the decoding of the user’s brain signals. Here we review the current state of the art in the BCI field, discussing the main components of such an interface and illustrating ongoing research questions and prototypes for controlling a large variety of devices, from virtual keyboards for communication to robotics systems to replace lost motor functions and even clinical interventions for motor rehabilitation after a stroke. The article concludes with some insights into the future of BCI.
Suicidio y crítica cultural en la medicina española del siglo XIX
2015
El presente trabajo explora el destacado papel del suicidio en la crítica cultural desplegada por los médicos españoles del siglo XIX a través de un análisis de los principales modelos teóricos que inspiraron sus aportaciones en torno a la causación del mismo. En la primera mitad del siglo, el factor etiológico más discutido fueron las pasiones, las cuales, de acuerdo con el espiritualismo dominante, actuaban en tensión permanente con un yo reflexivo, consciente y dueño de su libre albedrío. Posteriormente, y en el contexto de una progresiva somatización de los fenómenos morales e intelectuales, la concepción del suicidio como un acto libre del individuo fue modificándose hasta considerarlo…

Post-Secular Identity? Developing a New Approach to Religion in International Relations and IR Studies
2021
In spite of the increasing presence of religion in international relations with various publications observing this presence and numerous authorities calling for the inclusion of religion into mainstream research, there is no universal consent to recognize religion’s role in IR. In our opinion, the only way to reconcile IR with the international reality in which religion has been and will remain present in the foreseeable future is for the researchers themselves to construct—especially those oriented towards broad, non-Western perspective—a new face of the discipline, the face which in this article we call the post-secular identity of IR study. Assuming that identity is first and foremost a…
Glial ion transport and volume control.
1991
K(+)-induced glial swelling results from an intricate interaction of transport and diffusion processes and metabolic stimulation, with many open questions remaining. Our concept of the major mechanisms involved can be summarized as follows: high extracellular K+ causes a burst-like stimulation of Na+/K+ ATPase and, hence, increases the metabolic demands. Lactate is produced; the cell is slightly acidified. To maintain a normal intracellular pH, the Na+/K+ antiporter extrudes protons and supplies Na+ for further Na+/K+ exchange. In addition, K+ ions enter the cell via membrane channels or furosemide-inhibitable transport. K+, Cl-, and lactate- ions accumulate as the osmotic basis for cell sw…
Un condiscípulo español de Alexander von Humboldt en la Bergakademie de Freiberg: Josef Ricarte y su informe sobre el método de amalgamación de Born …
2004
[ES] Se estudia la labor de Joseph Ricarte, pensionado en París y luego en Centroeuropa, para estudiar el método de amalgamación de Born. El trabajo de Ricarte fue especialmente interesante en la Escuela de minas de Schemnitz, a cargo del profesor Antón Ruprecht, en 1787, aunque también se exponen los viajes de aprendizaje con Andrés Manuel del Río por diversas regiones centroeuropeas (Alta y baja Hungría, Austria, Bohemia,etc...) hasta su llegada a Freiberg, en Sajonia, donde estudiaron con A. Werner y fueron compañeros de Alexander von Humboldt. Acompaña al artículo una disertación de Ricarte sobre las mejoras introducidas por Ruprecht al método del barón de Born.
Novel·les de ciència. La ciència i la tecnologia en la literatura
2014
La major part de la literatura sovint intenta oblidar el paper essencial que la ciencia i la tecnologia modernes juguen en la configuracio de les societats actuals i en la manera de viure-hi. Fou Jules Verne, fa ja uns 150 anys, qui va comencar a ser conscient de la necessitat que la ciencia i la tecnologia intervinguessin de manera activa en la narrativa moderna. Ho va anomenar la «novel·la de la ciencia». Mes endavant, el genere literari de la ciencia-fi ccio sembla haver assolit el paper d’aquella novel·la de la ciencia que Jules Verne va comencar. Amb aixo, la ciencia-ficcio es configura tambe com una narrativa adient per a l’aprenentatge del futur, ja que descriu diversos mons possible…
Autoantibody detection using indirect immunofluorescence on HEp-2 cells
2009
The detection of autoantibodies is an important element in the diagnosis and monitoring of disease progression in patients with autoimmune diseases. In laboratory diagnostic tests for connective tissue and autoimmune liver diseases, indirect immunofluorescence on HEp-2 cells plays a central role in a multistage diagnostic process. Despite the high quality of diagnostics, findings at different laboratories can differ considerably due to a lack of standardization, as well as subjective factors. The present paper formulates recommendations for the standardized processing and interpretation of the HEp-2 cell test for the detection of non-organ-specific (especially antinuclear) antibodies. It pr…
Tautology as presumptive meaning
2008
Ever since the seminal work of Paul Grice, tautologies such as Business is business have been discussed from a number of angles. While most approaches assume that tautological utterances have to do with the operation of conversational maxims, an integrated analysis is still lacking. This paper makes an attempt at analysing tautologies within the framework of Levinson (2000), who proposes a distinction between three pragmatic levels, namely Indexical Pragmatics, Gricean Pragmatics 1, and Gricean Pragmatics 2. It is shown that observations of Ward and Hirschberg (1991) on the exclusion of alternatives, the claim of Autenrieth (1997) that the second NP in nominal equatives is predicative, and …
