The Radio Extension of the Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy
No full textIn the present talk I discuss the modern technique of ultra-high energy cosmic-ray detection by measuring the radio emission produced during the development of air-showers induced by these particles. One of the successful implementation of this technique is the Tunka-Rex (Tunka Radio Extension) experiment operating since 2012 in the frame of the Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy (TAIGA) located in Siberia nearby Lake Baikal. I discuss the radio detection of air-showers, the methods for reconstruction of primary energy and mass composition, the main results of Tunka-Rex as well as benefits of multi-component detection of cosmic-rays in the frame of TAIGA
Cosmic rays measurements with Tunka Radio Extension
No full textTunka Radio Extension (Tunka-Rex) is an array of 63 radio antennas deployed at the Tunka Advanced Instrument for cosmic rays and Gamma Astronomy (TAIGA). This antenna array detects radio pulses produced by deflection of charged component of air-shower in Earth\u27s magnetic field during its development. Tunka-Rex measures cosmic rays of energies above
100 PeV starting from 2012. The hardware description, methods and latest results are given in this presentation

Reconstruction of air-shower parameters with a sparse radio array
Get PDFThe present study consists of two main parts: a theoretical description of the methods of air-shower reconstruction using the radio technique, and analysis of Tunka-Rex data using the developed methods
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
