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
Twin-grid array as 3.6 GHz epidermal antenna for potential backscattering 5G communication
No full textEmerging 5G infrastructures can boost innovative paradigms for future wearable and epidermal devices exploiting low-power (even passive) wireless backscattering-based communication. To compensate high body and path losses, and to extend the read range, array configurations are required. This letter proposes a flexible monolithic epidermal layout, based on the Krauss array concept, that operates at 3.6 GHz, and it is suitable to be directly attached to the human body. The antenna involves a dual-grid configuration with a main radiating grid backed by a grid reflector placed in touch with the skin. Overall, the number of conductors and dielectric substrates is minimized with benefit to breathability. The antenna is suitable for surface feeding and produces a broadside radiation. Parametric analysis is performed, and an optimal configuration of a four-cell grid is derived and experimentally demonstrated to provide a maximum gain of more than 6 dBi
