Sobre las identidades narrativas

La interpretación narrativa es un modo de conectar la obra de arte con la historia y a partir de ahí configurar la identidad narrativa en términos dinámicos. La interpretación narrativa es un camino viable para el pensar cuando éste trata de dar cuenta de formas problemáticas de arte, como el arte actual, ya que tiene la ventaja de trabajar con el contexto de la obra en vez de tratarla aisladamente. Una obra es lo que es gracias a sus conexiones con obras anteriores y posteriores. La narratividad es probablemente el mejor modo de establecer, explicar y comprender estas conexiones. El objetivo de este artículo es mostrar que puede haber un tipo de interpretación que configure la identidad narrativa de la obra y que esta identidad no se restringe a la identificación, sino que crea una identidad dinámica para la obra.My contention is that narrative interpretation is a way to connect the artwork with preceding and succeeding artworks and that through these connections it configures the work’s narrative identity as a dynamic one. Narrative interpretation is a clear option to deal with problematic art forms, such as the avant-garde, for example, because it has the advantage of dealing with the context of the work instead of treating it as an isolated object. A given work –whether an artwork or not- is so through its connections with preceding and succeeding works. Narrative is perhaps the best way of establishing, explaining and understanding these connections. My aim is to show that there can be a kind of interpretation that brings forth the narrative identity of the artwork and that this identity is not restricted to a means for identification, but is also the configuration of a dynamic identity for the artwork

El arte, la muerte, la historia. El problema del tiempo y la historia en las reflexiones estéticas hegelianas

This paper analyzes the role that time and history have within Hegelian philosophy, particularly within Hegelian Aesthetics. One central idea is that during the XIX century the relationship between art and time is postulated very emphatically; the Hegelian Aesthetics are assumed in this paper as a paradigm of the afore mentioned relationship. From the point of view of the aesthetic ontology, the paper inquires about the roles that time and history have in the art field and also it questions what is the significance of the art history and if art is essentially historic. It investigates the theoretical consequences for the Ontology of the introduction of art and history in Aesthetics. History is one of the ways of being of time, but not the only one; therefore, there are other kinds of temporalities that fit the artwork. From the historical and temporal assumptions, the paper problematizes ideas like the universality of beauty and the eternity of the Idea.Este texto lleva a cabo un análisis del papel que cumplen el tiempo y la historia dentro de la filosofía hegeliana, específicamente en la estética. Se parte de la idea de que en el siglo XIX se instaura radicalmente la relación entre arte y tiempo y se toma la estética hegeliana como paradigma de dicha relación. Desde el horizonte de la ontología estética, se reflexiona acerca del papel que cumplen el tiempo y la historia en el arte y se pregunta qué significa la construcción de una historia del arte y si el arte es esencialmente histórico. Asimismo, se investiga sobre las consecuencias de la introducción de tiempo e historia para la estética en su relación con la ontología, después se pregunta qué significa pensar el ser desde el tiempo y la historia. Se asume además que la historia es uno de los modos de ser del tiempo, mas no el único, y que por tanto, al arte corresponden también otro tipo de temporalidades. Desde los postulados históricos y temporales, se problematizan ideas como la universalidad de la belleza y la eternidad de la Idea

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| &lt; 0.03 at 95% confidence level.

Measurement of b jet shapes in proton-proton collisions at root s=5.02 TeV

We present the first study of charged-hadron production associated with jets originating from b quarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data sample used in this study was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 27.4 pb(-1). To characterize the jet substructure, the differential jet shapes, defined as the normalized transverse momentum distribution of charged hadrons as a function of angular distance from the jet axis, are measured for b jets. In addition to the jet shapes, the per-jet yields of charged particles associated with b jets are also quantified, again as a function of the angular distance with respect to the jet axis. Extracted jet shape and particle yield distributions for b jets are compared with results for inclusive jets, as well as with the predictions from the pythia and herwig++ event generators.Peer reviewe

Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets

Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.Peer reviewe

Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at root s(NN)=5.02 TeV

The second-order Fourier coefficients (v(2)) characterizing the azimuthal distributions of Y(1S) and Y(2S) mesons produced in PbPb collisions at root s(NN) = 5.02 TeV are studied. The Y mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb(-1). The scalar product method is used to extract the v2 coefficients of the azimuthal distributions. Results are reported for the rapidity range vertical bar y vertical bar < 2.4, in the transverse momentum interval 0 < pT < 50 GeV/c, and in three centrality ranges of 10-30%, 30-50% and 50-90%. In contrast to the J/psi mesons, the measured v(2) values for the Y mesons are found to be consistent with zero. (C) 2021 The Author(s). Published by Elsevier B.V.Peer reviewe
