Incomplete reconnection in sawtooth crashes in ASDEX Upgrade
No full textThe temporal evolution of the sawtooth crash in ASDEX Upgrade Ohmic and ECRH heated discharges is analysed using a heuristic reconnection model to simulate measured ECE signals. The method turns out to be well suited to detect islands of width above 0.1-0.2 times the mixing radius; for smaller island widths, we cannot distinguish between the resistive and the ideal mode. Thus, the nature of the precursor oscillation cannot be fully resolved. In contrast, we find that during the crash phase, reconnection is incomplete and a large island persists that fully reconnects on a slower time-scale after the crash. The observations are consistent with a recent sawtooth model
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
