EN TORNO A LA CULTURA POLÍTICA DE LA ALTA MAGISTRATURA

2008

International audience; One of the most striking facts in the political history of the monarchy in early modern Spain is the growth of a significant state bureaucracy. At the same time, there occurred an intensive reflection on justice, law and government which led to the publication of numerous political and legal treatises. If we know, at least theoretically, how the main institutions of the government worked, we are still ignorant about much concerning the social and cultural profile of the royal officials of the monarchy. Firstly, the goal of this contribution is to offer an analysis on a particular kind of bureaucrats, namely the lawyers, by placing them in their political and institut…

Las enfermedades exantemáticas: el sarampión y la escarlatina en las revistas pediátricas españolas (1900-1950)

2013

La revolución microbiológica de finales del siglo XIX supuso un cambio profundo en el abordaje tanto de la patología, la clínica y la terapéutica de las enfermedades infecciosas, como en la medicina preventiva y la epidemiología. Este nuevo enfoque restó protagonismo al pensamiento hipocrático sobre los aires, las aguas y los lugares, que aún influía en el estudio de las enfermedades. Desde esta perspectiva este trabajo se propone mostrar dos enfermedades exantemáticas, sarampión y escarlatina, caracterizadas por una gran morbi-mortalidad, y de las que hasta la fecha no se ha realizado un examen profundo en historia de la medicina española. Para conseguirlo se han recogido las publicaciones…

Search for a Dark Leptophilic Scalar in e(+) e(-) Collisions

2020

Many scenarios of physics beyond the standard model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constraints on additional scalars with masses in the MeV to GeV range could be significantly weakened if they interact predominantly with leptons rather than quarks. At an e+e- collider, such a leptophilic scalar (φL) would be produced predominantly through radiation from a τ lepton. We report herein a search for e+e-→τ+τ-φL, φL→ℓ+ℓ- (ℓ=e, μ) using data collected by the BABAR experiment at SLAC. No significant signal is observed, and we set limits on the φL coupling to leptons in the range 0.04<mφL<7.0 GeV. These bounds s…

Particle identification in ALICE: a Bayesian approach

2016

We present a Bayesian approach to particle identification (PID) within the ALICE experiment. The aim is to more effectively combine the particle identification capabilities of its various detectors. After a brief explanation of the adopted methodology and formalism, the performance of the Bayesian PID approach for charged pions, kaons and protons in the central barrel of ALICE is studied. PID is performed via measurements of specific energy loss ($\mathrm{d}E/\mathrm{d}x$) and time-of-flight. PID efficiencies and misidentification probabilities are extracted and compared with Monte Carlo simulations using high-purity samples of identified particles in the decay channels ${\rm K}^0_S \righta…

Measurement of the Lund jet plane using charged particles in 13 TeV proton-proton collisions with the ATLAS detector

2020

The prevalence of hadronic jets at the LHC requires that a deep understanding of jet formation and structure is achieved in order to reach the highest levels of experimental and theoretical precision. There have been many measurements of jet substructure at the LHC and previous colliders, but the targeted observables mix physical effects from various origins. Based on a recent proposal to factorize physical effects, this Letter presents a double-differential cross-section measurement of the Lund jet plane using 139  fb−1 of √s=13  TeV proton-proton collision data collected with the ATLAS detector using jets with transverse momentum above 675 GeV. The measurement uses charged particles to ac…

Transitivity and Evaluation in American and Spanish Parliamentary discourse: the 2015 State of the Union Address in the US vs. the 2015 State of the …

2022

The present study explores the interplay of evaluation and transitivity in an American and Spanish parliamentary debate by President Obama and PM Rajoy aiming at legitimizing their actions and at convincing candidates to vote for them in the upcoming elections. A further objective is to investigate whether the transitivity and appraisal analyses illustrate the politicians’ ideological positions. Within the general framework of Systemic Functional Linguistics (SFL), we use the results obtained for Appraisal following Martin and White’s appraisal scheme [Cabrejas-Peñuelas, A. B. (2020). Metaphor, metonymy and evaluation as political devices in American and Spanish parliamentary political disc…

Propuesta de mejora del gráfico de control c mediante el diseño óptimo de un esquema de muestreo doble

2019

En el control estadístico de procesos, la herramienta más utilizada para monitorear el número promedio de no conformidades es el gráfico de Shewhart C. Este gráfico se basa en el supuesto de que el número de no conformidades en las muestras es bien modelada por la distribución de Poisson, y aunque es un gráfico fácil de usar, su capacidad para detectar cambios pequeños es baja, por lo que es necesario tomar tamaños de muestras grandes, aumentando los costos relacionados con el muestreo. Por lo anterior, se propone el desarrollo de un esquema de muestreo doble para el gráfico de control C. Además de derivar la expresión matemática adecuada para la evaluación exacta de la Longitud Media de Co…

Measurements of underlying-event properties using neutral and charged particles in pp collisions at root s=900 GeV and root s=7 TeV with the ATLAS de…

2011

We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. Events were selected using a minimum-bias trigger which required a charged particle in scintillation counters on either side of the interaction point. Particle flows, sensitive to the underlying event, are measured using clusters of energy in the ATLAS calorimeters, taking advantage of their fine granularity. No Monte Carlo generator used in this analysis can accurately describe the measurements. The results are independent of those based on charged particles measured by the ATLAS …

Luminosity determination in pp collisions at s=7 TeV using the ATLAS detector at the LHC

2011

Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at s√=7 TeV are presented. The luminosity is independently determined using several detectors and multiple algorithms, each having different acceptances, systematic uncertainties and sensitivity to background. The ratios of the luminosities obtained from these methods are monitored as a function of time and of μ, the average number of inelastic interactions per bunch crossing. Residual time- and μ-dependence between the methods is less than 2% for 0<μ<2.5. Absolute luminosity calibrations, performed using beam separation scans, have a common systematic uncertainty of ±11%, do…
