Matronas y cambio social en la segunda mitad del siglo XX. De mujeres y partos
2014
Esta investigación profundiza en el análisis de los cambios que se produjeron en la asistencia al parto en la segunda mitad del siglo XX en nuestro país, como consecuencia de las transformaciones políticas, culturales, económicas y sociales. Hemos avanzado en el conocimiento de lo que significó la puesta en marcha de las grandes unidades hospitalarias y en qué medida se transformó la atención al parto de un acto íntimo que se realizaba en el propio domicilio de la parturienta a un acto médico, altamente tecnificado y medicalizado, por tanto, de menor cercanía humana entre la mujer y las profesionales que le ayudan en su parto. Hemos centrado nuestra atención en el hospital de referencia de …
The strong coupling constant: State of the art and the decade ahead
2022
This document provides a comprehensive summary of the state-of-the-art, challenges, and prospects in the experimental and theoretical study of the strong coupling $\alpha_s$. The current status of the seven methods presently used to determine $\alpha_s$ based on: (i) lattice QCD, (ii) hadronic $\tau$ decays, (iii) deep-inelastic scattering and parton distribution functions fits, (iv) electroweak boson decays, hadronic final-states in (v) e+e-, (vi) e-p, and (vii) p-p collisions, and (viii) quarkonia decays and masses, are reviewed. Novel $\alpha_s$ determinations are discussed, as well as the averaging method used to obtain the PDG world-average value at the reference Z boson mass scale, $\…
Open-source QCD analysis of nuclear parton distribution functions at NLO and NNLO
2019
We present new sets of nuclear parton distribution functions (nPDFs) at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO). Our analyses are based on deeply inelastic scattering data with charged-lepton and neutrino beams on nuclear targets. In addition, a set of proton baseline PDFs is fitted within the same framework with the same theoretical assumptions. The results of this global QCD analysis are compared to existing nPDF sets and to the fitted cross sections. Also, the uncertainties resulting from the limited constraining power of the included experimental data are presented. The published work is based on an open-source tool, xFitter, which has been modified to be ap…
