Calomyscinae Vorontsov and Potapova 1979
No full text<p>Subfamily Calomyscinae Vorontsov and Potapova, 1979. Zool. Zh., 58:1393.</p> <p> COMMENTS: Although earlier authors associated it with New World sigmodontines, Vorontsov and Potapova (1979) recognized <i>Calomyscus's</i> combination of distinctive features by setting it apart as a tribe in the subfamily Cricetinae of the family Cricetidae. Pavlinov (1980c) kept it with sigmodontines, and Agusti (1989:387) summarily regarded it as the only living member of the Myocricetodontinae. Carleton and Musser (1984:313) discussed the different taxonomic assignments of <i>Calomyscus,</i> its characteristics that did not fit with Old World hamsters (Cricetinae), and the dental similarities between <i>Calomyscus</i> and Miocene <i>Democricetodon,</i> and remarked that <i>" Calomyscus</i> could be justifiably classified among the cricetodontines, a group hitherto supposed extinct."</p>Published as part of <i>Guy G.

Phase Composition, Surface Morphology, and Dielectric Properties of Poly(Vinylidene Fluoride)–Cobalt Ferrite Composite Films Depending on Thickness
No full textThis study investigates the effect of polyvinylidene fluoride–CoFe2O4 (PVDF-CFO) composite film thickness on their supramolecular structure, phase composition, and dielectric properties. The composites were synthesized from PVDF with CFO nanoparticles using the Dr. Blade method to obtain film thicknesses ranging from 15 to 58 μm. The data obtained show that the thinner film (15 μm) has a higher β-phase content compared to the thicker films (58 μm), as confirmed by FTIR and Raman spectroscopy. Scanning electron microscopy (SEM) showed that increasing film thickness within the studied range leads to the development of larger spherulitic structures and increased porosity. Atomic force microscopy (AFM) analysis also showed that thicker films have higher tensile strength due to their larger cross-sectional area, while thinner films exhibit lower elasticity. A more uniform microstructure and an increased electroactive phase in thin films result in increased permittivity, which is critical for PVDF-based sensors and energy devices

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
