Waveform Reconstruction of IBD and Muon Events in JUNO
No full textThe JUNO (Jiangmen Underground Neutrino Observatory) experiment is a multi-purpose neutrino experiment currently under construction in Jiangmen, China. The primary goal is to determine the neutrino mass hierarchy by measuring reactor antineutrinos at a baseline of 53 km. The 20 kton liquid-scintillator detector aims at achieving an outstanding energy resolution of 3%/E(MeV)‾‾‾‾‾‾‾‾√

of Inverse Beta Decay (IBD) events. Hence, the charge and arrival times of individual photons have to be reconstructed with great precision. Furthermore, the suppression of the cosmic muon background is performed by a partial volume veto depending on the first hit time and charge of the muon signals. The IBD waveform study is based on the deconvolution method, which unfolds the photo-electron hit pattern and the single photo-electron response. The results of IBD photo-electron reconstruction and the reconstruction of the first hit time of muons and the corresponding charge are presented
The Jiangmen Underground Neutrino Observatory
No full textThe Jiangmen Underground Neutrino Observatory (JUNO) is a next generation multi-purpose antineutrino detector currently under construction in Jiangmen, China. The central detector contains 20 kton of liquid scintillator and is equipped with 18,000 20 inch and 25,000 3 inch PMTs. The surrounding water pool serves as Cherenkov veto detector allowing muon track reconstruction for a partial volume veto of the central detector. Measuring reactor antineutrinos of two powerplants at a baseline of 53 km, the unprecedented design energy resolution is 3% at 1 MeV. The main physics goal is to determine the neutrino mass hierarchy within six years of run time with a significance of 3-4 sigma. Additional physics goals are the precise measurement of the solar neutrinos, geo-neutrinos, supernova burst neutrinos, the diffuse supernova neutrino background as well as the search for proton decays. Data taking is expected to start in 2021. This talk reviews the current status of the project and the physics goals. Furthermore, the contributions of the German collaboration groups are summarized

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Towards Measuring the Electromagnetic Structure of η’ Mesons with the CLAS g12 Experiment
No full textVariations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
