Memoria y pasado español en la narrativa de Andrés Trapiello

[ES]Esta tesis doctoral surge en el contexto de las iniciativas sociales, políticas y culturales respecto a la recuperación de la memoria del pasado español focalizado en la Guerra Civil –y en el que estamos asentados desde las últimas décadas del siglo XX– pero cuyas manifestaciones más importantes se han producido durante la primera década del presente siglo. El de la memoria es un tema muy controvertido y difícil de abordar, sobre todo porque una de sus principales características radica en la interdisciplinariedad de su estudio, aunque la principal materia de estudio aquí es la literatura, y en concreto la narrativa española llamada “de la memoria”, y cuya producción está viviendo sus horas más notables de la pluma de autores como Andrés Trapiello. Las obras de Trapiello trascienden las motivaciones o características personales para convertirse en el mejor ejemplo de la evolución del tratamiento que la “memoria histórica” ha recibido en la sociedad, pues es sabido que la literatura parte de los cambios sociales y se adapta a ellos, ofreciendo a los lectores aquello que necesitan o reclaman en cada momento. La originalidad de Andrés Trapiello (León, 1953) reside en que ha sido capaz de congregar varios subgéneros narrativos en un mismo producto, la ya aludida “novela de memoria”; de este modo nos encontramos con novelas policiales (Los amigos del crimen perfecto, 2003), ensayos (Las armas y las letras, 1994), diarios (Días y noches, 2000), novelas con tintes autoficticios (El buque fantasma, 1992), novelas documentales (La noche de los Cuatro Caminos, 2001) u obras marcadas por la polifonía en las que en cada capítulo cambia el narrador, convirtiéndose casi en relatos reticulares (Ayer no más, 2003)

Andrés Trapiello: An Autofictional Author?

Desde finales del siglo XX asistimos a una corriente literaria en continuo auge y cuyo origen lo encontramos en los años 70 en Doubrovsky, se trata de la “autoficción”, un híbrido literario y cultural que permite al egocéntrico autor postmoderno mostrar su egolatría sin la necesidad de tener que recurrir a un género desprestigiado como la autobiografía (Alberca, 2009: 18). La autoficción que encontramos en El buque fantasma (1992) y en Ayer no más (2012) del leonés Andrés Trapiello tiene la peculiaridad de ajustarse al “principio de indecidibilidad” creado por él mismo (Trapiello, 2013) y que se basa en la imposibilidad de decidir si lo que se cuenta en la novela es real o no, lo cual representa la victoria de la veracidad sobre lo verídico.The theory of the “autofiction” created by Doubrovsky en the seventies experienced a huge increase during the last two decades of the 20th Century. This technique, a hybrid between literature and cultural studies, allows the postmodern author to show his egotism without resorting to the discredited autobiography (Alberca, 2009:18). The Spanish author Andrés Trapiello has developed this autofiction in his own way, calling it “indecidibilidad” (Trapiello, 2013). Among Trapiello’s narrative production, El buque fantasma (1992) and Ayer no más (2012) are two of his novels where we find autofiction more clearly. This “indecidibilidad” consists in the affirmation that it is impossible to say if the story we find in the novel is true or not, about the veracity versus truthful facts

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

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

Calibration of the CMS hadron calorimeters using proton-proton collision data at root s=13 TeV

Methods are presented for calibrating the hadron calorimeter system of theCMSetector at the LHC. The hadron calorimeters of the CMS experiment are sampling calorimeters of brass and scintillator, and are in the form of one central detector and two endcaps. These calorimeters cover pseudorapidities vertical bar eta vertical bar ee data. The energy scale of the outer calorimeters has been determined with test beam data and is confirmed through data with high transverse momentum jets. In this paper, we present the details of the calibration methods and accuracy.Peer reviewe

Search for top squark pair production in a final state with two tau leptons in proton-proton collisions at root s=13 TeV

A search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at s = 13 TeV is presented in a final state containing hadronically decaying tau leptons and large missing transverse momentum. This final state is highly sensitive to high-tan beta or higgsino-like scenarios in which decays of electroweak gauginos to tau leptons are dominant. The search uses a data set corresponding to an integrated luminosity of 77.2 fb(-1), which was recorded with the CMS detector during 2016 and 2017. No significant excess is observed with respect to the background prediction. Exclusion limits at 95% confidence level are presented in the top squark and lightest neutralino mass plane within the framework of simplified models, in which top squark masses up to 1100 GeV are excluded for a nearly massless neutralino.Peer reviewe

Measurement of the t(t)over-barb(b)over-bar production cross section in the all-jet final state in pp collisions at root s=13 TeV

A measurement of the production cross section of top quark pairs in association with two b jets (t (t) over barb (b) over bar) is presented using data collected in proton-proton collisions at root s=13 TeV by the CMS detector at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The cross section is measured in the all-jet decay channel of the top quark pair by selecting events containing at least eight jets, of which at least two are identified as originating from the hadronization of b quarks. A combination of multivariate analysis techniques is used to reduce the large background from multijet events not containing a top quark pair, and to help discriminate between jets originating from top quark decays and other additional jets. The cross section is determined for the total phase space to be 5.5 +/- 0.3 (stat)(-1.3)(+)(1.6) (syst)pb and also measured for two fiducial t (t) over barb (b) over bar, definitions. The measured cross sections are found to be larger than theoretical predictions by a factor of 1.5-2.4, corresponding to 1-2 standard deviations. (C) 2020 The Author.

Search for a Light Charged Higgs Boson Decaying to a W Boson and a CP-Odd Higgs Boson in Final States with eμμ or μμμ in Proton-Proton Collisions at √s=13 TeV

A search for a light charged Higgs boson (H+) decaying to a W boson and a CP-odd Higgs boson (A) in final states with eμμ or μμμ is performed using data from pp collisions at √s=13  TeV, recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9  fb−1. In this search, it is assumed that the H+ boson is produced in decays of top quarks, and the A boson decays to two oppositely charged muons. The presence of signals for H+ boson masses between 100 and 160 GeV and A boson masses between 15 and 75 GeV is investigated. No evidence for the production of the H+ boson is found. Upper limits at 95% confidence level are obtained on the combined branching fraction for the decay chain, t→bH+→bW+A→bW+μ+μ−, of 1.9×10−6 to 8.6×10−6, depending on the masses of the H+ and A bosons. These are the first limits for these decay modes of the H+ and A bosons.Peer reviewe

Search for supersymmetry in proton-proton collisions at 13 TeV in final states with jets and missing transverse momentum

Results are reported from a search for supersymmetric particles in the final state with multiple jets and large missing transverse momentum. The search uses a sample of proton-proton collisions at root s = 13 TeV collected with the CMS detector in 2016-2018, corresponding to an integrated luminosity of 137 fb(-1), representing essentially the full LHC Run 2 data sample. The analysis is performed in a four-dimensional search region defined in terms of the number of jets, the number of tagged bottom quark jets, the scalar sum of jet transverse momenta, and the magnitude of the vector sum of jet transverse momenta. No significant excess in the event yield is observed relative to the expected background contributions from standard model processes. Limits on the pair production of gluinos and squarks are obtained in the framework of simplified models for supersymmetric particle production and decay processes. Assuming the lightest supersymmetric particle to be a neutralino, lower limits on the gluino mass as large as 2000 to 2310 GeV are obtained at 95% confidence level, while lower limits on the squark mass as large as 1190 to 1630 GeV are obtained, depending on the production scenario.Peer reviewe

Search for dark matter particles produced in association with a Higgs boson in proton-proton collisions at √s = 13 TeV

© 2020, The Author(s). A search for dark matter (DM) particles is performed using events with a Higgs boson candidate and large missing transverse momentum. The analysis is based on proton- proton collision data at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb−1. The search is performed in five Higgs boson decay channels: h → b b ¯ , γγ, τ+τ−, W+W−, and ZZ. The results from the individual channels are combined to maximize the sensitivity of the analysis. No significant excess over the expected standard model background is observed in any of the five channels or in their combination. Limits are set on DM production in the context of two simplified models. The results are also interpreted in terms of a spin-independent DM-nucleon scattering cross section and compared to those from direct-detection DM experiments. This is the first search for DM particles produced in association with a Higgs boson decaying to a pair of W or Z bosons, and the first statistical combination based on five Higgs boson decay channels.
