Global conservative and multipeakon conservative solutions for the modified camassa-holm system with coupling effects
2014
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2014/606249 This paper investigates the continuation of solutions to the modified coupled two-component Camassa-Holm system after wave breaking. The underlying problem is rather challenging due to the mutual coupling effect between two components in the system. By introducing a novel transformation that makes use of a skillfully defined characteristic and a set of newly defined variables, the original system is converted into a Lagrangian equivalent system, from which the global conservative solution is obtained, which further allows for the e…
Search for anomalous Wtb couplings in single top quark production
2008
Made available in DSpace on 2022-04-28T20:46:40Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-11-25 Science and Technology Facilities Council In 0.9fb-1 of pp̄ collisions, the D0 Collaboration presented evidence for single top quark production in events with an isolated lepton, missing transverse momentum, and two to four jets. We examine these data to study the Lorentz structure of the Wtb coupling. The standard model predicts a left-handed vector coupling at the Wtb vertex. The most general lowest dimension, CP-conserving Lagrangian admits right-handed vector and left- or right-handed tensor couplings as well. We find that the data prefer the left-handed vector coupling and set u…

Complexation behaviour of hexadentate ligands possessing N2O4and N2O2S2cores: differential reactivity towards Co(ii), Ni(ii) and Zn(ii) salts and str…
2004
Reactions of divalent metal salts of Co, Ni and Zn with 1,2-di(salicylaldimino-o-phenylthio) ethane (H2L1) and 1,2-di(naphthaldimino-o-phenylthio) ethane (H2L2), having N2O2S2 cores, and 1,2-di(O-salicylaldimino-o-hydroxyphenyl) ethane (H2L3), having a N2O4 core, have been explored. Out of the three ligands and the nine products obtained from the corresponding reactions, two ligands and seven products were crystallographically characterized. However, all the ligands and the products were characterized by analytical and spectral methods. Reaction of H2L1 and H2L2 with Co(II) salts results in oxidative cleavage of the C-S bond to produce a Co(III) product bound to two dissimilar tridentate li…
Science and art from a transevolutionary perspective
2018
From its origins, the human species has manipulated not only the real world but also the figurative one. While that manipulative action of the human species over both worlds was critical for the survival of the species in the beginning of its evolution -now transevolution-, it is also true that in the subsequent culture those worlds have been approached by two trades with highly different conceptual bases, science and art. In this paper I hold the thesis that both trades are necessary to know how to be in the world as well as how to transform it in an appropriate way.
La activación de la inmigración
2020
Los enfoques convencionales sobre las migraciones han tendido a considerar frecuentemente a los inmigrantes como sujetos pasivos en sus procesos de incorporación a las sociedades de recepción. En cambio, cada vez contamos con más muestras de la iniciativa de los propios inmigrantes como actores de procesos de cambio, así como nuevas perspectivas de investigación que tratan de dar cuenta de este giro: el reconocimiento de la autonomía de las migraciones, la relevancia de las capacidades y la agencia de los migrantes en diferentes ámbitos y su contribución al desarrollo de las sociedades de recepción. En realidad, los inmigrantes despliegan diversas estrategias, luchas y resistencias contribu…
Politics of solidarity in the context of European heritage : The cases of the European Solidarity Centre and Hambach Castle
2019
This article explores the politics of solidarity in the framework of constructing a common cultural heritage of the European Union. The politics of solidarity stems from the notion of solidarity embedded to European heritage. We use critical heritage studies as a theoretical approach that understands heritage as an inherently dissonant social construct, produced by various actors according to political, economic and social interests. The study analyses empirical data from the European Heritage Label (EHL), a flagship heritage action of the EU that communicates shared values and a sense of identification to European citizens. Our empirical data includes ethnographic observation as well as in…
Blocos/batucadas en los barrios obreros de Madrid. La percusión colectiva como cultura de clase
2019
Influenciados por los blocos afro y los movimientos antisistema europeos, los primeros blocos de tambores brasileños (batucadas) comienzan a formarse en Madrid en los inicios del milenio. Su continua presencia en las calles durante los años de la crisis y posteriormente en el 15M los ha convertido en un fenómeno cultural imprescindible en cualquier reivindicación popular progresista. Algunos de ellos, ubicados y vinculados a los movimientos vecinales y/o anticapitalistas de los barrios obreros de la capital, forman parte de la vida cotidiana de su entorno a través de su participación en sus reivindicaciones y fiestas. Con su música, entendida como herramienta de transformación social, contr…
Socio-spatial differentiation in transition: a preliminary comparative analysis of post-soviet St Petersburg and Riga
2020
Research into the socio-spatial dynamics in Central European cities is an important area of contemporary transition studies. Open issues in this domain range from defining a theoretical framework to data availability and methodological approaches. As to the former aspect, recent literature focuses on the hybrid nature of the post-socialist urban space, which underwent modernization in the conditions of globalization and economic liberalization; the earlier model of spatial development changed dramatically as a result. The multi-scalar and comparative approaches may shed new light on the complex patterns of urban socio-spatial differentiation and its post-Soviet dynamics. Growing regional so…
