L.A. Belyaev and the Archeology of the Volga Region
No full textThe article is dedicated to the jubilee of Leonid Andreevich Belyaev, a renowned Russian archaeologist, scientific figure, Corresponding Member of the Russian Academy of Sciences, and chief editor of the Russian Archaeology journal. The milestones of his life are considered along with the role of the Volga region archaeology in his development as a researcher, as well as the contribution made by Leonid Andreevich to the study of the medieval antiquities of the Volga region. Today, Leonid Andreevich Belyaev is one of the most recognised archaeologists-medievalists solving the fundamental theoretical problems of historical science, managing large field projects, and establishing new directions in the scientific research process. The range of Leonid Andreevich’s scientific interests vividly characterizes the tremendous scope of his personality
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Toward ELF Magnetic Fields for the Treatment of Cancer
No full textThe possibility of a link between childhood leukemia and other cancers and extremely low-frequency magnetic fields has given rise to several epidemiological studies. The existence of amplitude and frequency windows prompts the need of screening through the different parameters of exposure for two reasons: optimization and avoidance of undesired effects. In principle, the most purist, safest way of going from experiments with cellular cultures to experiments with small animals and then finally to clinical trials with humans would be to use homogeneous fields in these several stages. In this way, dosimetry would be much easier, but the drawback would be substantial: for the treatment of humans, much bigger facilities should be used, in order to house devices big enough to generate homogeneous fields in a volume equal to or greater than a human being.Fil: Makinistian, Leonardo.

Supersymmetry status and phenomenology at the Large Hadron Collider
No full textLarge Hadron Collider (LHC) has a great chance to finally reveal supersymmetry which remains a compelling theory for over 30 years in spite of lack of its discovery.It might be around the corner the present LHC era with sensitive dark matter search experiments and international linear collider hopefully coming up in the near future
Extension of Belyaev-Zelivinski method of rotation as intrinsic nuclear excitation
No full textThe method of Belyaev and Zelevinski for handling the rotational collective states of deformed nuclei has been extended. It is shown how a [J(J+1)]2 term naturally occurs in the energy spectrum of a rotational band for even-even nuclei. This is accomplished by modifying the assumption that Belyaev and Zelevinski imposed on their |n\u3e states. This leads to a definite relationship between the coefficient of the J(J+1) and [J(J+1)]2 terms in the energy spectrum. This technique is applied to a single isolated j-level and to an arbitrary level scheme
SUSY:Theory Status in the Light of Experimental Constraints
No full textSupersymmetry remains compelling theory over 30 years in spite of lack of its discovery. It could be already near the corner our days, therefore present and upcoming experiments are crucial for constraining or even discovery of the supersymmetry
Variations on the Author
No full text“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
No full textWe 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
