Symbolic Spaces in Late Capitalism, Where Art is A Proposal and not a Conclusion
Mariano O. de Blas
Journal of Arts and Humanities , 2013,
Abstract: Capitalism is the predominant conceptual system configuring and forming our reality. It is difficult, perhaps almost impossible, to imagine another one, because we are immersed in the conceptual approaches of this reality, the one of capitalism. Art is able to represent, symbolically and accurately this conceptual reality, but also to encourage us to imagine other realities even if it is only able display this one accurately (without critic). The concept of this reality is based now on consumption through virtual identities. The value of art is affected by this premise, meaning that the artist is valuable mainly because he is converted into a logo, a valuable signature on the work. This phenomenon not only reflects our conceptual approach to reality but also unveils it, revealing new aspects of our reality and what we think about it. However, art is able to go further and present different approaches to our concepts about reality. It could mean that art promotes us to imagine other realities, at least unconsciously, for both art producers and viewers. Finally, this scheme has to be included in a new revolutionary tool, the web, a virtual multidimensional space, where contemporary art takes part. Therefore, in the “space” of the web, art can communicate more than ever and can transform itself and present this transformation beyond the established limits, contributing to produce a more flexible and imaginative way of thinking.
Electroweak limits on physics beyond the Standard Model
J. de Blas
Physics , 2013, DOI: 10.1051/epjconf/20136019008
Abstract: We briefly review the global Standard Model fit to electroweak precision data, and discuss the status of electroweak constraints on new interactions. We follow a general effective Lagrangian approach to obtain model-independent limits on the dimension-six operators, as well as on several common new physics extensions.
Enigmatic barrows without offerings: Monte Deva (Gijón) and Berducedo (Allande), in Asturias
de Blas Cortina, Miguel ángel
Trabajos de Prehistoria , 2004,
Abstract: The structural simplicity of two large barrows and their lack of grave goods make enigmatic tomb types, that although part of the megalithic tradition, could be located in the Early Bronze Age (Monte Deva V). Their easy classification as “poor tombs” (large poor tombs?) ought to raise the possibility of other interpretations. The barrows, built by poorly nucleated societies in a context of very low population density, and with limited possibilities of exchange, are likely to be more due to a concrete funerary form, whose variations are considered, than to exclusively economic reasons. La simplicidad estructural de dos grandes túmulos y la carencia de ofrendas sintetizan modalidades sepulcrales enigmáticas que, si bien instaladas en la tradición megalítica, podrían situarse en el Bronce Antiguo (Monte Deva V). A su cómoda catalogación como “tumbas pobres” ( grandes tumbas pobres?) se le debe oponer la plausibilidad de otras opciones. Construidos por sociedades poco nucleadas, en un contexto de baja densidad demográfica y de limitadas posibilidades de intercambio, es probable que se deban más a una precisa normativa funeraria, cuyas variantes son consideradas, que a razones exclusivamente económicas.
Un rara avis de la alfareria Prehistórica en Asturias: las sugerencias inducidas del Vaso Neolítico (IV milenio a. de C. TL) de la Hoz de los Cavíos (Pilo a).
De Blas Cortina, Miguel ángel
Munibe Antropologia-Arkeologia , 2011,
Abstract: La cerámica prehistórica anterior al Edad del Hierro es apenas conocida en Asturias, tal vez por su propia escasez, probablemente sustituida por recipientes corruptibles. El hallazgo solitario de un vaso de gran calidad técnica y cuidada decoración, depositado en una peque a cueva situada en el fondo umbrío e insalubre de un desfiladero da pie a distintas consideraciones sobre su posible significado. Fechada la vasija por el método TL en el IV milenio a. de C., su ubicación en un claro paraje de conexión y ruptura entre ambientes naturales muy distintos, abona la hipótesis de la anotación simbólica de los lugares de paso y de articulación de universos económicamente complementarios propiciando, además, la revisión de la naturaleza y distribución las huellas de la vida neolítica en un territorio crucial en sector centro-este asturiano.
The Least Supersymmetric Signals at the LHC
de Blas, J.;Delgado, A.;Ostdiek, B.
High Energy Physics - Phenomenology , 2013,
Abstract: We study the implications at the LHC for the minimal (least) version of the supersymmetric standard model. In this model supersymmetry is broken by gravity and extra gauge interactions effects, providing a spectrum similar in several aspects to that in natural supersymmetric scenarios. Having the first two generations of sparticles partially decoupled means that any significant signal can only involve gauginos and the third family of sfermions. In practice, the signals are dominated by gluino production with subsequent decays into the stop sector. As we show, for gluino masses below 2300 GeV, a discovery at the LHC is possible at \sqrt{s}=14 TeV, but will require large integrated luminosities.
Electroweak constraints on new physics
F. del Aguila,J. de Blas
Physics , 2011, DOI: 10.1002/prop.201100068
Abstract: We briefly review the limits on new interactions implied by electroweak precision data. Special attention is payed to the bounds on the Higgs boson mass. We also comment on the required cancellation among the new contributions to precisely measured electroweak observables in any Standard Model extension, if the new particles have to evade the indirect constraints on their couplings and masses but still remain at the LHC reach.

Global Constraints on Lepton-Quark Contact Interactions
J. de Blas,M. Chala,Jose Santiago
Physics , 2013, DOI: 10.1103/PhysRevD.88.095011
Abstract: The Large Hadron Collider can do precision physics at a level that is competitive with electroweak precision constraints when probing physics beyond the Standard Model. We present a simple yet general parameterization of the effect of an arbitrary number of lepton-quark contact interactions on any di-lepton observable at hadron colliders. This parameterization can be easily adopted by the experimental collaborations to put bounds on arbitrary combinations of lepton-quark contact interactions. We compute the corresponding bounds from current di-lepton resonance searches at the LHC and find that they are competitive with and often complementary to indirect constraints from electroweak precision data. We combine all current constraints in a global analysis to obtain the most stringent bounds on lepton-quark contact interactions. We also show that the high-energy phase of the LHC has a unique potential in terms of discovery and discrimination power among different types of lepton-quark contact interactions.
Renormalization Group Constraints on New Top Interactions from Electroweak Precision Data
Jorge de Blas,Mikael Chala,Jose Santiago
Physics , 2015,
Abstract: Anomalous interactions involving the top quark contribute to some of the most difficult observables to directly access experimentally. They can give however a sizeable correction to very precisely measured observables at the loop level. Using a model-independent effective Lagrangian approach, we present the leading indirect constraints on dimension-six effective operators involving the top quark from electroweak precision data. They represent the most stringent constraints on these interactions, some of which may be directly testable in future colliders.

de Blas,A; Bargalló,R; de la Hoz,J;
Información tecnológica , 2004, DOI: 10.4067/S0718-07642004000300005
Abstract: in this paper the preisach model as an alternative to analytical approximations to characterize magnetic hysteresis in numerical methods applied to calculations or analyses in electrical engineering, is presented the fundamentals of the classical preisach model are explained showing alternatives for its definition. a fit is proposed for the method chosen which obtains good results using a small number of experimental curves. a generic algorithm for its solution as a numerical method is also presented. finally, an alternative assay is proposed which allows obtaining experimental data for definition of the model without the need for sophisticated equipment . it is concluded that the classical preisach model is as simple a system for execution as the numerical method, permitting prediction of the value of the induction for an instantaneous value of field intensity, based on prior performance
