No full textResistive Plate Chambers are the dedicated trigger muon detector for the Compact Muon Solenoid experiment at the Large Hadron Collider at CERN. HV50 is one of the parameter under study to eventually spot any aging effect. The comparative study is done for Barrel and Endcap region particularly, and as a whole too confirming the excellent behavior of RPC detector and fulfillment of requirement as per decided before the upgrade
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
Variations 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Differenzielle Querschnittsmessung der ̄-Produktion und Interpretation im Kontext der effektiven Feldtheorie unter Verwendung der ATLAS-Detektordaten bei √= 13 TeV
No full textThe study of the production of top quark pairs in association with a photon (̄ ) probes the top-photon coupling (). This coupling is sensitive to new particle interactions Beyond the Standard Model (BSM) physics. The measurement of the absolute differential cross-section in the single-lepton channel of ̄ process is performed in a fiducial region at the particle level. The measurement is carried out using the Run-2 data collected at the ATLAS detector of the Large Hadron Collider (LHC) that corresponds to the centre-of-mass-energy of √ = 13 TeV at the instantaneous luminosity of 139 fb⁻¹. This measurement is employed to study the sensitivity of the ̄ process BSM by using the effective field theory (EFT) framework. The fiducial region is defined by requiring one lepton ( or ), one photon, and at least four jets where one of them is identified as a b-jet. The measurement is performed as a function of the transverse momentum of the photon (T()), and the absolute pseudorapidity of the photon (|()|). The EFT framework used for the interpretation provides higher-order operators that parameterize the potential deviations from the Standard Model (SM). Three of these are considered here for the ̄ process: , , and to model the sensitivity of the process. The photon T in the ̄ process is sensitive to these operators, therefore the cross-section measurement study as a function of is exploited in the EFT interpretation. The estimated 1 limits for the EFT operators , , and are [-0.82, 1.02], [-0.24, 0.14], and [-0.46, 0.97], respectively.Die Untersuchung der Produktion von Top-Quark-Paaren in Verbindung mit einem Photon (̄ ) untersucht die Top-Photon-Kopplung (). Diese Kopplung ist empfindlich gegenüber neuen Teilchenwechselwirkungen jenseits des Standardmodells (BSM-Physik). Die Messung des absoluten Differentialquerschnitts im Einzel-Lepton-Kanal des ̄-Prozesses wird im Fiducialbereich auf Teilchenebene durchgeführt. Die Messung wird anhand der Run-2-Daten durchgeführt, die am ATLAS-Detektor des Large Hadron Collider (LHC) gesammelt wurden und einer Schwerpunktsenergie von √ = 13 TeV bei einer momentanen Luminosität von 139 fb⁻¹ entsprechen. Diese Messung wird verwendet, um die Empfindlichkeit des ̄-Prozesses BSM unter Verwendung des Rahmens der effektiven Feldtheorie (EFT) zu untersuchen. Der Fiducial-Bereich wird definiert durch die Anforderung eines Leptons ( oder ), eines Photons und mindestens vier Jets, von denen einer als b-Jet identifiziert wird. Die Messung wird als Funktion des transversalen Impulses des Photons (T()) und der absoluten Pseudorapidität des Photons (|()|) durchgeführt. Der für die Interpretation verwendete EFT-Rahmen liefert Operatoren höherer Ordnung, die die potenziellen Abweichungen vom Standardmodell (SM) parametrisieren. Drei davon werden hier für den ̄-Prozess berücksichtigt: , und zur Modellierung der Empfindlichkeit des Prozesses. Das Photon T im ̄-Prozess ist empfindlich gegenüber diesen Operatoren, daher wird die Untersuchung der Querschnittsmessung als Funktion von in der EFT-Interpretation genutzt. Die geschätzten 1-Grenzwerte für die EFT-Operatoren , und sind [-0,82, 1,02], [-0,24, 0,14], and [-0,46, 0,97]
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
