Flavour and Higgs physics near the Fermi scale
No full textAfter a discussion of the hierarchy problem of the Fermi scale, we study
the
flavour and Higgs boson(s) phenomenology of new physics close to it, both
in general and in the specifi c cases of Supersymmetry and composite Higgs
models. First, we promote the approximate U(2)3 symmetry exhibited by the
quark sector of the Standard Model to be a more fundamental symmetry of
Nature, and explore its phenomenological consequences from an effective fi eld
theory point of view. We also study the embedding of natural Supersymmetry
within the U(2)3 framework, focusing in particular on the pattern of
flavour
and CP violation in B decays. Then we consider the CP-even scalar sector of
the next-to-minimal supersymmetric Standard Model. We quantify the impact
of current and foreseen measurements of the Higgs boson signal strengths on
the physical parameters, deriving analytical relations for this purpose, and we
outline a possible overall strategy to search for the other Higgs scalars. Finally
we analyze the constraints from
flavour and electroweak precison tests on composite
Higgs models, for di fferent representations of the composite fermions,
and comparing the case of an anarchic
flavour structure to models with a
U(3)3 and a U(2)3
flavour symmetry
One or more Higgs bosons?
Full text linkNow that one has been found, the search for signs of more scalars is a primary task of current and future experiments. In the motivated hypothesis that the extra Higgs bosons of the next-to-minimal supersymmetric Standard Model (NMSSM) be the lightest new particles around, we outline a possible overall strategy to search for signs of the CP-even states. This work complements Ref. arXiv:1304.3670.Now that one has been found, the search for signs of more scalars is a primary task of current and future experiments.

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
Photogrammetry for 3D representation of human remains from the necropolis KR-N1 in Dhofar (Southern Oman): digital technology applied to osteo-archaeological studies
Full text linkThe poorly preserved human bones discovered during the DHOMIAP Project excavation of the necropolis KR-N1 in the area of Khor Rori (Dhofar, Sultanate of Oman) were an opportunity to apply, for the first time in Dhofar’s pre-Islamic funerary contexts, 3D photogrammetry to osteo-archaeological studies. The low economic engagement and the execution speed make this technique essential in the documentation of barely accessible archaeological remains and
contexts, as already witnessed by previous studies conducted outside this research area. This paper aims to find a more appropriate method and setting for 3D model photogrammetric reconstruction of human remains, demonstrating the importance of this digital technology for the study of poorly preserved osteo-archaeological remains. For these purposes, the results obtained using two different settings for image acquisition (one with macro and one with standard lens) were compared and discussed
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
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
