The analysis of the cultural Cold War in Latin America has experienced a growing interest from disciplinary fields such as cultural history or literary studies. In this line of work, and with the aim ...of contributing to a transatlantic approach to the problem, the special issue "Cultural ties of socialist and transatlantic friendship: Latin American writers and the Eastern Bloc during the Cold War" emphasizes the study of the interrelationships between Latin American literature and various European socialist countries. For this, it attends to a corpus of a plural nature: from fictional texts or analysis of periodicals to, above all, non-fiction texts that authors of diverse origins (Argentina, Uruguay, Chile, Cuba or Mexico) produced after passing through nations located beyond the Iron Curtain.
The Cold War motivated the international cultural field to replicate the geopolitical tensions and affinities that gripped the world.The positive side of this process contributed to the expansion of ...national literatures in environments where traditionally they had not found great resonance. However, the perverse effects were translated into various exclusions and dogmatic impositions that undermined the autonomy of writers. Latin American literature experienced, in this context, a process of globalization. The aim of this text is to testify to the complexities inherent to the reception of this literature in socialist Romania, for which a remarkable set of periodicals is analyzed, especially from 1964 to 1971.The translation, edition and physical reception of the Latin American authors themselves it was produced according to changing structural determinations, which show the evolution of the Romanian political-cultural field itself, but also thanks to individual gatekeepers who brought Latin American literature closer to the Romanian public.
After having announced the statistically significant observation (5.6σ) of the new exotic πK atom, the DIRAC experiment at the CERN proton synchrotron presents the measurement of the corresponding ...atom lifetime, based on the full πK data sample: τ=(5.5−2.8+5.0)×10−15 s. By means of a precise relation (≈1%) between atom lifetime and scattering length, the following value for the S-wave isospin-odd πK scattering length a0−=13(a1/2−a3/2) has been derived: |a0−|=(0.072−0.020+0.031)Mπ−1.
The observation of hydrogenlike πK atoms, consisting of π^{-}K^{+} or π^{+}K^{-} mesons, is presented. The atoms are produced by 24 GeV/c protons from the CERN PS accelerator, interacting with ...platinum or nickel foil targets. The breakup (ionization) of πK atoms in the same targets yields characteristic πK pairs, called "atomic pairs," with small relative momenta Q in the pair center-of-mass system. The upgraded DIRAC experiment observed 349±62 such atomic πK pairs, corresponding to a signal of 5.6 standard deviations. This is the first statistically significant observation of the strange dimesonic πK atom.
The adapted DIRAC experiment at the CERN PS accelerator observed for the first time long-lived hydrogenlike π^{+}π^{-} atoms, produced by protons hitting a beryllium target. A part of these atoms ...crossed the gap of 96 mm between the target and a 2.1 μm thick platinum foil, in which most of them dissociated. Analyzing the observed number of atomic pairs, n_{A}^{L}=436_{-61}^{+157}|_{tot}, the lifetime of the 2p state is found to be τ_{2p}=(0.45_{-0.30}^{+1.08}|_{tot})×10^{-11} s, not contradicting the corresponding QED 2p state lifetime τ_{2p}^{QED}=1.17×10^{-11} s. This lifetime value is three orders of magnitude larger than our previously measured value of the π^{+}π^{-} atom ground state lifetime τ=(3.15_{-0.26}^{+0.28}|_{tot})×10^{-15} s. Further studies of long-lived π^{+}π^{-} atoms will allow us to measure energy differences between p and s atomic states and so to discriminate between the isoscalar and isotensor ππ scattering lengths with the aim to check QCD predictions.
This special issue-'Indigenismo on Stage: Artistic Expression and the Inter-American Indigenista Movement in the Mid-Twentieth Century'-aims to present the staging of indigenismo by analyzing its ...'indianizing' side. The process we call 'indianization' consists of promoting the recognition of indigenous cultural and especially artistic 'specificities', as determined by the inter-American indigenismo that consolidated in Pátzcuaro, Mexico, starting with the first Inter-American Conference on Indian Life in 1940. Concretely, this special issue addresses the staging of indigenist indianization in two crucial domains: 1) 'indigenous' artistic expression as it was promoted by indigenismo; and 2) the abstraction/generalization of 'indigeneity' and 'indigenous people' that operationalized and successfully spread this indigenismo. These two concerns bring together the contributions to this issue (articles, a review essay, and a collective dialogue), which explicitly adopt a transnational perspective or, when they focus on specific countries, consider their indigenist connections to the rest of the Americas. Grounded on the analysis of a notable variety of objects of study (statuary, music, handicrafts, photography, engraving, and theatre), this special issue follows an itinerary that runs from the early twentieth century to the present.
This article examines the treatment of the figure of the 'Indian' in the Bolivian theater of the 1920s. It opens up with a presentation of the theatrical work of Bolivia's generación del 21. The ...selected corpus is then read as a set of texts that discuss the intersections between the notions of the 'Bolivian nation' and 'indigeneity,' two key elements in the intellectual debates of early 20
th
century Bolivia. It attends to the connection between these plays and Bolivian indigenismo and inter-American indigenismo more broadly, thereby highlighting how the 'Indian' was understood to be a contemporary subject constrained by specific material circumstances. The article considers the plays Supay marca (1928), by Zacarías Monje Ortiz, which premiered in 1920; two plays by Antonio Díaz Villamil: La voz de la quena (1988), which premiered in 1922 and La Rosita (1928 2001), which premiered in 1925; and Los lobos del Altiplano (1930), by Federico Ávila.
The data centre at the Galician Institute of High Energy Physics (IGFAE) of the Santiago de Compostela University (USC) is a computing cluster with about 150 nodes and 1250 cores that hosts the LHCb ...Tiers 2 and 3. In this small data centre, and of course in similar or bigger ones, it is very important to keep optimal conditions of temperature, humidity and pressure. Therefore, it is a necessity to monitor the environment and be able to trigger alarms when operating outside the recommended settings. There are currently many tools and systems developed for data centre monitoring, but until recent years all of them were of commercial nature and expensive. In recent years there has been an increasing interest in the use of technologies based on Arduino due to its open hardware licensing and the low cost of this type of components. In this article we describe the system developed to monitor IGFAE's data centre, which integrates an Arduino controlled sensor network with the Nagios monitoring software. Sensors of several types, temperature, humidity and pressure, are connected to the Arduino board. The Nagios software is in charge of monitoring the various sensors and, with the help of Nagiosgraph, to keep track of the historic data and to produce the plots. An Arduino program, developed in house, provides the Nagios plugin with the readout of one or several sensors depending on the plugin's request. The Nagios plugin for reading the temperature sensors also broadcasts an SNMP trap when the temperature gets out of the allowed operating range.
