Transverse momentum spectra and nuclear modification factors of charged particles in pp, p-Pb and Pb-Pb collisions at the LHC
2018
We report the measured transverse momentum ($p_{\rm T}$) spectra of primary charged particles from pp, p-Pb and Pb-Pb collisions at a center-of-mass energy $\sqrt{s_{\rm NN}} = 5.02$ TeV in the kinematic range of $0.15<p_{\rm T}<50$ GeV/$c$ and $|\eta|< 0.8$. A significant improvement of systematic uncertainties motivated the reanalysis of data in pp and Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV, as well as in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV, which is also presented. Spectra from Pb-Pb collisions are presented in nine centrality intervals and are compared to a reference spectrum from pp collisions scaled by the number of binary nucleon-nucleon collisions. For cent…
Visibilidad internacional de la investigación de la Universitat de València (Web of Science 2000-2009)
2013
En esta publicación se ofrecen los primeros resultados del análisis de la producción científica de la Universitat de València para la década 2000-2009 realizado mediante la explotación de las bases de datos de la Web of Science (SCI, SSCI y A&HCI). La información está organizada en dos capítulos. El primero, dedicado a ofrecer una imagen general de la producción de la Universitat, permite apreciar el volumen de publicaciones circulantes en esas bases de datos, su crecimiento en el periodo estudiado, la tipología documental, el idioma de publicación y su clasificación temática. Para esto se han utilizado dos clasificaciones, la primera más detallada basada en las 247 categorías temáticas en …
La biblioteca en el espacio ciudadano. Reflexiones a partir de la investigación española sobre el usuario de la información, 2005-2019
2021
Los últimos datos sobre el escaso uso de las bibliotecas españolas cuestionan la utilidad de este servicio en la cotidianidad ciudadana. Paralelamente, un movimiento dentro de la Biblioteconomía y Documentación que habla de la biblioteca social, participativa o del bien común, busca ampliar el espacio ciudadano que ésta ocupa. Este trabajo se centra en las implicaciones que para este propósito tienen las últimas investigaciones españolas sobre usuarios de la información. Primero, los datos revelan la escasa participación de los profesionales en estas investigaciones. Segundo, abundan aquellas que se centran en la evaluación de unidades de información, pero escasean las dirigidas a obtener d…
SHORTNESS OF FILUM TERMINALE REPRESENT AN ANATOMICAL SPECIFC FEATURES IN FIBROMYALGIIA : A NUCLEAR MAGNETIC RESONANCE AND CLINICAL STUDY
2015
BACKGROUND: we aimed to assess whether shortness of filum terminale (FT) can represent a specific feature of fibromyalgia. Therefore we investigated benefits coming from FT section with a mini-invasive technique in patients with fibromyalgia. Filum terminale disease (FD), described firstly in 1996, is consequence of an abnormal traction exerted on spinal cord since FT is shorter than usual. Fibromyalgia syndrome (FS) is featured by chronic widespread musculoskeletal pain associated with stiffness and extra-skeletal symptoms affecting many organs and systems. Filum terminale disease and fibromyalgia syndrome share common clinical features in at least one subset of patients. METHODS: we evalu…
Kurzweil-Henstock type integral on zero-dimensional group and some of its application
2008
A Kurzweil-Henstock type integral on a zero-dimensional abelian group is used to recover by generalized Fourier formulas the coefficients of the series with respect to the characters of such groups, in the compact case, and to obtain an inversion formula for multiplicative integral transforms, in the locally compact case.
The Intention-to-Treat Effect of Bridging Treatments in the Setting of Milan Criteria–In Patients Waiting for Liver Transplantation
2019
In patients with hepatocellular carcinoma (HCC) meeting the Milan criteria (MC), the benefit of locoregional therapies (LRTs) in the context of liver transplantation (LT) is still debated. Initial biases in the selection between treated and untreated patients have yielded conflicting reported results. The study aimed to identify, using a competing risk analysis, risk factors for HCC-dependent LT failure, defined as pretransplant tumor-related delisting or posttransplant recurrence. The study was registered at www.clinicaltrials.gov (identification number NCT03723304). In order to offset the initial limitations of the investigated population, an inverse probability of treatment weighting (IP…
Mechanical, thermal and acoustical characterizations of an insulating bio-based composite made from sunflower stalks particles and chitosan
2014
International audience; This study has for objective the determination of thermal, mechanical and acoustical properties of insulating bio-based composite made with chitosan and sunflower's stalks particles. An experimental design was established to find the size grading of particles, the ratio chitosan/sunflower particles and the stress of compaction influencing the thermal and mechanical properties. Composites with a thermal conductivity $(\kappa)$ of 0.056 W/m/K, a maximum stress $(\sigma_{\text{max}})$ of 2 MPa and an acoustic coefficient of absorption $(\alpha)$ of 0.2 were obtained with a ratio of chitosan of 4.3% (w/w) and a size grading of particles higher to 3 mm. These mechanical a…
Characterization and Tuning of Ultra High Gradient Permanent Magnet Quadrupoles
2009
The application of quadrupole devices with high field gradients and small apertures requires precise control over higher order multipole field components. We present a new scheme for performance control and tuning, which allows the illumination of most of the quadrupole device aperture because of the reduction of higher order field components. Consequently, the size of the aperture can be minimized to match the beam size achieving field gradients of up to $500\text{ }\text{ }\mathrm{T}\text{ }{\mathrm{m}}^{\ensuremath{-}1}$ at good imaging quality. The characterization method based on a Hall probe measurement and a Fourier analysis was confirmed using the high quality electron beam at the M…
Plan S: challenges and opportunities in Spain
2019
Spain is one of the most active European countries in the open access (OA) movement. Although the gold route has scarcely been used, the green route has been intensively implemented through fulfilment of European and national mandates and the development of institutional policies. Plan S is becoming a disruptive element in the context of scientific communication, and Spain’s possible adherence to Plan S could imply technical challenges in journals and repositories, additional costs that are difficult to estimate, or refusal to accept the Plan on the part of researchers (based on the loss of freedom to choose the journal in which to publish). However, the implementation of Plan S in Spain wo…
[Spanish funded paediatric research: Contribution of Anales de Pediatría to its dissemination].
2017
Objective: To identify Spanish funded paediatric research published in general paediatric journals included in the Web of Science (WoS) from 2010 to 2014 and those published in Anales de Pediatría. To examine the relationship between funding and the prestige of the journals. To describe the journal conditions to meet the open access criteria. Material and method: Spanish funded paediatric articles (FA) were identified by using the WoS Funding Agency field, and by reviewing the original documents for Anales de Pediatria (AP). For the FA published in AP the number and kind of funding agencies were identified. The possible differences in citations between FA and non-funded was assessed for art…
