Structure Of The Sun's Core: Evolutional And Seismological Constraints
No full textIntroduction A variety of solar models (namely, models of stars having solar values of mass, radius, luminosity) is a subject of our study. The hydrogen profile in the star's interior is usually determined by course of the evolution, but we also consider models with arbitrary hydrogen profiles or diffusion profiles also. Applying additional restrictions on the model which follow from recent helioseismic results we consider the question of existence of the models. These restrictions are: 1) calibration of the surface helium abundance and the specific entropy in the convection zone (Vorontsov et al. 1991; Baturin, Vorontsov 1994; there are few results on the helium calibration but we used cited ones because they contain simultaneous determination of the helium and the entropy); 2) estimation of the convection zone depth (Christensen-Dalsgaard et al., 1991); 3) sound speed profile inferred from oscillation frequencies (Vorontsov, Shibahashi 1992)
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
Study of the field-induced evolution of the domain geometry in lithium niobate and lithium tantalate single crystals by in-situ optical method
No full textEvolution of the domain structure geometry including quantitative statistic information about domain walls' orientation has been in-situ studied by optical microscopy and light diffraction with subsequent image analysis in congruent, stoichiometric and MgO doped lithium niobate (LN) and lithium tantalate (LT) single crystals. 2D lithographic pattern with about 20 µm period in CLN was used to study the simplified case of domain kinetics. The appearance of the switching stage with domain walls oriented in both X and Y directions, was shown experimentally. Such behavior was predicted by computer simulation of the domain growth through merging of the neighboring domains
