Introducción a las técnicas de neuroimagen

La tomografía por emisión de positrones (PET) y la resonancia magnética (RM) ofrecen la posibilidad de estudiar la anatomía del cerebro y su plasticidad, y de detectar las zonas que se activan o las redes que tienen su actividad sincronizada al realizar determinadas tareas. Se hará una breve introducción de distintas técnicas de neuroimagen con ejemplos de aplicación.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Double fermiophobic Higgs boson production at the LHC and LC

We consider the phenomenology of a fermiophobic Higgs boson (h_f) at the Large Hadron Collider (LHC) and a e+e- Linear Collider (LC). At both machines the standard production mechanisms which rely on the coupling h_fVV (V=W,Z) can be very suppressed at large tan beta. In such cases the complementary channels pp to H^\pm h_f, A^0 h_f and e+e- to A^0 h_f offer promising cross-sections. Together with the potentially large branching ratios for H^\pm to h_fW* and A^0 to h_fZ*, these mechanisms would give rise to double h_f production, leading to signatures of gamma gamma gamma gamma, gamma gamma VV and VVVV.Comment: 19 pages, 9 figures, expanded discussion, fig.1 changed slightly, version to appear in Phys.Rev.

Aceite de oliva y cáncer

In the last years, numerous studies have examined the association of dietary fat and cancer. Polyunsaturated fatty acids (PUFA) from n-6 family display a strong promoting effect, this may be partially due to the especially prone to lipid peroxidation of PUFA that leads to formation of aldehydes, which react with DNA bases, forming genotoxic exocyclic etheno(epsilon)-adducts. On the contrary, there are growing evidences that monounsaturated oils, like olive oil, may be associated with a decreased risk of some cancers. However, the epidemiological data do not fully agree with the experimental ones previously published. Minor compounds from (extra virgin) olive oil, mainly phenolics like hydroxytyrosol and tocopherol, are antioxidants and radical scavenging. They can minimize the amount of reactive oxygen species (ROS) generated by fatty acid peroxidation and in the case of monounsaturated fatty acids (MUFA) the DNA damage can be reduced by a lower lipid peroxidation.Numerosos estudios en los últimos años han determinado la existencia de una asociación entre las grasas procedentes de la dieta y el cáncer. Los ácidos grasos poliinsaturados (PUFA) de la familia n -6 pueden tener efectos proliferativos y angiogénicos, lo cual se debe en parte a que son especialmente sensibles a la peroxidación lipídica, formándose aldehídos que reaccionan con las bases del ADN y por lo tanto aductos exocíclicos con propiedades genotóxicas. Por el contrario, el consumo de dietas ricas en ácidos grasos monoinsaturados (MUFA) está relacionado con un menor riesgo de distintos tipos de cáncer. Si bien, los datos epidemiológicos no siempre concuerdan con los datos experimentales. Los componentes menores del aceite de oliva (extra virgen), fundamentalmente el hidroxitirosol y tocoferol, son antioxidantes y secuestradores de radicales libres. Pueden minimizar la cantidad de especies reactivas de oxígeno que se generan por la peroxidación lipídica y además los MUFA son menos sensibles a la oxidación, por lo que se reduce el daño del ADN.The authors would like to acknowledge to the Ministry of Education and Science (ECI) of the Spanish Government for supporting this manuscript (grant AGL2001-0584).

As provas no discurso. Estabelecer os limites

Despite the extensive search that has been done on the phenomenon of evidentiality in the discourse, i.e. the coding of the information source, there are still terminological and conceptual discrepancies that need to be laid out. The present paper presents a theoretical framework of evidentiality. It starts with an examination of the scope of evidentiality in terms of grammar and semantics, ending up with a full understanding of the notion as a functionalconceptual domain. The discussion also focuses on the relationship between evidentiality and epistemic modality since this is still an open-ended issue in the field. We support that a thorough study of particular evidential forms, such as reportative evidential, would be needed as a vibrant continuation of this theoretical revisionA pesar de la investigación extensa que se ha hecho sobre el fenómeno de la evidencialidad en el discurso, es decir, la codificación de la fuente de la información, todavía hay discrepancias terminológicas y conceptuales que necesitan ser consideradas. El presente artículo presenta una discusión teórica de la evidencialidad. Comienza con un examen del ámbito de la evidencialidad en cuanto a la gramática y semántica, terminando con una comprensión completa del concepto como un ámbito funcional-conceptual. La discusión también se centra en la relación entre la evidencialidad y la modalidad epistémica, dado que todavía es un tema abierto en el campo. Apoyamos que un estudio exhaustivo de formas evidenciales concretas, tales como los evidenciales reportativos, sería necesario como continuación dinámica de esta revisión bibliográficaMalgré les recherches approfondies qui ont été menées sur le phénomène de la preuve dans le discours, c'est-à-dire le codage de la source d'information, il existe encore des divergences terminologiques et conceptuelles qui doivent être prises en compte. Cet article présente une discussion théorique sur la force probante. Elle commence par un examen du domaine de la preuve en termes de grammaire et de sémantique, et se termine par une compréhension complète du concept en tant que domaine fonctionnel-conceptuel. La discussion se concentre également sur la relation entre l'évidence et le mode épistémique, car il s'agit d'une question encore ouverte dans ce domaine. Nous soutenons qu'une étude exhaustive des formes concrètes de preuve, telles que les preuves de signalement, serait nécessaire en tant que continuation dynamique de cette analyse documentair

Phenomenological methodology for assessing the influence of flow conditions on the acoustic response of exhaust aftertreatment systems

[EN] The increasing limits of standards on aerosol and gaseous emissions from internal combustion engines have led to the progressive inclusion of different exhaust aftertreatment systems (EATS) as a part of the powertrain. Regulated emissions are generally abated making use of devices based on monolithic structures with different chemical functions. As a side effect, wave transmission across the device is affected and so is the boundary at the exhaust line inlet, so that the design of the latter is in turn affected. While some models are available for the prediction of these effects, the geometrical complexity of many devices makes still necessary in many cases to rely on experimental measurements, which cannot cover all the diversity of flow conditions under which these devices operate. To overcome this limitation, a phenomenological methodology is proposed in this work that allows for the sound extrapolation of experimental results to flow conditions different from those used in the measurements. The transfer matrix is obtained from tests in an impulse rig for different excitation amplitudes and mean flows. The experimental coefficients of the transmission matrix of the device are fitted to Fourier series. It allows treating the influence of the flow conditions on the acoustic response, which is manifested on changes in the characteristic periods, separately from the specific properties of every device. In order to provide predictive capabilities to the method, the Fourier series approach is coupled to a gas dynamics model able to account for the sensitivity of propagation velocity to variations in the flow conditions.

Arte paleolítico en Gorham's Cave (Gibraltar)

En este trabajo presentamos las novedades sobre el arte paleolítico de la cueva de Gorham. En el apartado mobiliar, abordamos una aproximación multidisciplinar en la que se analizan los datos petrográficos, deposicionales, diagenéticos, tafonómicos y antrópicos (técnicos o iconográficos) identificados en dos plaquetas de arte mueble. El arte parietal de Gorham se amplía con las manifestaciones localizadas en una Galería ubicada al final del cavernamiento. En ambos casos, la procedencia estratigráfica o los rasgos estilísticos permiten su atribución al Magdaleniense.We present the news on Palaeolithic art of Gorham’s cave. In paragraph of mobiliary art, we discuss a multidisciplinary approach in analyzing the petrographic, depositional, diagenetic, taphonomic and anthropic (technical or iconographic) data identified of two plaquettes of portable art. The Gorham’s cave art expands with the paintings located in the gallery located at the end of the cave. In both cases, the stratigraphic provenance or stylistic features allow its attribution to the Magdalenian
