Freeze-out radii extracted from three-pion cumulants in pp, p–Pb and Pb–Pb collisions at the LHC
2014
In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose-Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted using two-pion correlations, and characterize the system at the last stage of interaction, called kinetic freeze-out. In low-multiplicity collisions, unlike in high-multiplicity collisions, two-pion correlations are substantially altered by background correlations, e.g. mini-jets. Such correlations can be suppressed using three-pion cumulant correlations. We present the first measurements of the size of the system at freeze-out extracted from three-pion cumulant correl…

Los orígenes del Grial en las leyendas artúricas: interpretaciones cristianas y visiones simbólicas
2008
El presente artículo describe en síntesis los orígenes y desarrollo literario posterior del tema Grial, desde las primeras leyendas artúricas. Pese a sus posibles inicios paganos, el Grial pronto es identificado con el Santo Cáliz de la Última Cena, lo que imprime un carácter religioso a los relatos en los que se integra el motivo de su búsqueda como objeto perdido. A partir del siglo XIV esa religiosidad se desdibuja y cuando el tema del Grial sea recuperado para la literatura y el arte será como objeto de valor místico o espiritual, que supera el sentido netamente cristiano que tuvo en el Medievo. This paper traces the origins and literary development of the legend of the Holy Grial as it…

Stimulation of calcium uptake by norepinephrine or high external potassium in human calyces and renal pelvis.
1989
The effects of stimulation with either 10 mumol/l norepinephrine or 85 mmol/l extracellular potassium concentration on calcium uptake were studied in muscle strips from human renal calyces and from the renal pelvis. The apparent uptake of calcium under control conditions was essentially complete after 30 min. Stimulation of the muscle strips with norepinephrine or high external potassium significantly (P less than 0.05) increased the calcium uptake over the control values at 30 and 100 min, whereas 45Ca efflux was virtually not affected. It is concluded that the mechanical responses of the muscle strips to norepinephrine or high external potassium correspond with an increased uptake of calc…
Nomen est omen : kirjoittaja oppimassa nimien symboliikkaa Alice Munron novelleista
2021
Kirjoittamisen pro gradu tutkielmani tavoitteena on selvittää, miten valittu henkilöhahmon nimi ja luonne täsmäävät eli onko nimivalinta uskottava ja kuinka kirjailija voi kertoa henkilöhahmosta jotain olennaista pelkän nimen avulla. Pyrin löytämään kirjoittajana kirjoittamisen tutkimukseen vastauksia, kuinka nimillä tuodaan henkilöhahmoille syventävä identiteetti tai kuinka rakennan henkilöhahmon nimen avulla tarinaan uuden tason? Kanadalaisen Nobel-palkitun kirjailijan Alice Munron (s.1931) novellit ovat tunnettuja monitasoisuudestaan, mutta niiden henkilöhahmojen nimeämistä on tutkittu vähän tai sitä, käyttääkö Munro henkilöhahmojen nimeämisessä tietoista menetelmää. Analysoin otantaa Mu…

Investigations of Anisotropic Flow Using Multiparticle Azimuthal Correlations in pp, p-Pb, Xe-Xe, and Pb-Pb Collisions at the LHC
2019
Measurements of anisotropic flow coefficients ($v_n$) and their cross-correlations using two- and multi-particle cumulant methods are reported in collisions of pp at $\sqrt{s} = 13$ TeV, p-Pb at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV, Xe-Xe at $\sqrt{s_{_{\rm NN}}} = 5.44$ TeV, and Pb-Pb at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV recorded with the ALICE detector. The multiplicity dependence of $v_n$ is studied in a very wide range from 20 to 3000 particles produced in the mid-rapidity region $|��|<0.8$ for the transverse momentum range $0.2 < p_{\rm T} < 3.0$ GeV/$c$. An ordering of the coefficients $v_2 > v_3 > v_4$ is found in pp and p-Pb collisions, similar to that seen in large coll…
First measurement of quarkonium polarization in nuclear collisions at the LHC
2021
The polarization of inclusive J/$\psi$ and $\Upsilon(1{\rm S})$ produced in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=5.02$ TeV at the LHC is measured with the ALICE detector. The study is carried out by reconstructing the quarkonium through its decay to muon pairs in the rapidity region $2.5<y<4$ and measuring the polar and azimuthal angular distributions of the muons. The polarization parameters $\lambda_{\theta}$, $\lambda_{\phi}$ and $\lambda_{\theta\phi}$ are measured in the helicity and Collins-Soper reference frames, in the transverse momentum interval $2<p_{\rm T}<10$ GeV/$c$ and $p_{\rm T}<15$ GeV/$c$ for the J/$\psi$ and $\Upsilon(1{\rm S})$, respectively. The polarization parameter…
Performance of the ALICE experiment at the CERN LHC
2014
ALICE is the heavy-ion experiment at the CERN Large Hadron Collider. The experiment continuously took data during the first physics campaign of the machine from fall 2009 until early 2013, using proton and lead-ion beams. In this paper we describe the running environment and the data handling procedures, and discuss the performance of the ALICE detectors and analysis methods for various physics observables.
