One of the main goals of Hyper-Kamiokande is the study of asymmetry in the lepton sector using accelerator neutrino and anti-neutrino beams. In this document, the physics potential of a long baseline neutrino experiment using the Hyper-Kamiokande detector and a neutrino beam from the J-PARC proton synchrotron is presented. The analysis has been updated from the previous Letter of Intent [K. Abe et al., arXiv:1109.3262 [hep-ex]], based on the experience gained from the ongoing T2K experiment. With a total exposure of 7.5 MW 10 sec integrated proton beam power (corresponding to protons on target with a 30 GeV proton beam) to a -degree off-axis neutrino beam produced by the J-PARC proton synchrotron, it is expected that the phase can be determined to better than 19 degrees for all possible values of , and violation can be established with a statistical significance of more than () for () of the parameter space

One of the main goals of Hyper-Kamiokande is the study of asymmetry in the lepton sector using accelerator neutrino and anti-neutrino beams. In this paper, the physics potential of a long baseline neutrino experiment using the Hyper-Kamiokande detector and a neutrino beam from the J-PARC proton synchrotron is presented. The analysis uses the framework and systematic uncertainties derived from the ongoing T2K experiment. With a total exposure of 7.5 MW 10 sec integrated proton beam power (corresponding to protons on target with a 30 GeV proton beam) to a -degree off-axis neutrino beam, it is expected that the leptonic phase can be determined to better than 19 degrees for all possible values of , and violation can be established with a statistical significance of more than () for () of the parameter space. Using both appearance and disappearance data, the expected 1 uncertainty of is 0.015(0.006) for
Guía de estudio núm. 56. Julio Le Parc: luz en movimiento
No full textEn esta guía de estudio se lee una breve aproximación al origen del arte cinético y su desarrollo en Argentina y Venezuela, señalando la manera como este arte ha logrado transformar espacios públicos no convencionales mediante la experimentación con la luz y el involucramiento del espectador. Y es en este arte en el que se ubica el artista argentino Julio Le Parc, cuyas exploraciones de materiales y del espacio lo han convertido en un magnífico creador de experiencias cinéticas mediante la luz y el movimiento. Incluye imágenes de siete obras

Chemokines CCL3/MIP1α, CCL5/RANTES and CCL18/PARC are independent risk predictors of short-term mortality in patients with acute coronary syndromes
No full textCytokines play an important role in ischemic injury and repair. However, little is known about their prognostic value in cardiovascular disease. The aim of this study was to investigate the prognostic importance of chemokines CCL3/MIP-1α, CCL5/RANTES and CCL18/PARC for the risk of future cardiovascular events in patients with acute coronary syndromes (ACS). Baseline levels of CCL3/MIP-1α, CCL5/RANTES and CCL18/PARC were determined in ACS patients from the Bad Nauheim ACS II registry (n = 609). During the following 200 days, patients were monitored for the occurrence of fatal and non-fatal cardiovascular events. Patients with CCL3/MIP1α, CCL5/RANTES and CCL18/PARC concentrations in the highest tertile were associated with an increased risk of a fatal event during follow-up (HR: 2.19, 95%CI: 1.04–4.61 for CCL3/MIP1α, HR: 3.45, 95%CI: 1.54–7.72 for CCL5/RANTES and HR: 3.14, 95%CI: 1.33–7.46 for CCL18/PARC). This risk was highest for patients with all three biomarkers concentrations in the upper tertile (HR: 2.52, 95%CI: 1.11–5.65). Together with known risk predictors of cardiovascular events, CCL3/MIP-1α, CCL5/RANTES and CCL18/PARC combined improved the c-statistics from 0.74 to 0.81 (p = 0.007). In conclusion, CCL3/MIP-1α, CCL5/RANTES and CCL18/PARC are independently associated with the risk of short-term mortality in ACS patients. Combining all three biomarkers further increased their prognostic value

Living in the Luberon : Apraisal and perspectives of 5 years of Scientific column
No full textL’auteur montre, à travers les travaux présentés dans le Courrier scientifique du Parc naturel régional du Luberon dans de nombreuses disciplines des sciences de la nature et des sciences de l’homme, comment la région du Luberon constitue un espace marqué par l’approche patrimoniale plus ou moins induite par le Parc et ses actions. Il expose sommairement les incidences de cet état de fait sur les habitants et propose des pistes de recherche pour poursuivre ces investigations.Using the works presented in the Luberon regional natural Park scientific Column, which deals with numerous topics from natural sciences to human sciences, the author shows how the Luberon region constitutes a space marked by the patrimonial approach, more or less induced by the Park and its actions. The author also briefly explains the effects of this fact on the inhabitants and proposes research tracks to pursue these investigations
En papel y en movimiento: la experimentación en los inicios de la obra de Julio Le Parc
No full textEste trabajo aborda los años de formación y las primeras obras de Julio Le Parc en Buenos Aires, previos a su radicación en 1959 en París. Contempla su formación en el sistema de la Escuela Nacional de Bellas Artes, la relación con sus maestros, sus primeros dibujos y obras gráficas, como así también el momento de movilización estudiantil entre 1955 y 1958, cuando Le Parc fue lider de los estudiantes de Bellas Artes porteños. Siguiendo la pista de sus obras sobre papel y sus recorridos institucionales, este texto aborda los años de formación de Julio Le Parc en Buenos Aires en las décadas del 40 y del 50, indagando sobre cambios, persistencias y movimientos.Fil: Dolinko, Silvia Esther.
