Anticyclotomic main conjecture and the non-triviality of Rankin–Selberg L-values in Hida families
Get PDFWe prove the two-variable anticyclotomic Iwasawa main conjecture for Hida families and discuss its arithmetic application to a definite version of the horizontal non-vanishing conjecture, which is formulated in [LV11]. Our approach is based on the two-variable anticyclotomic control theorem for Selmer groups and the relation between the two-variable anticyclotomic L-function for Hida families built out of p-adic families of Gross points on definite Shimura curves studied in [CL16] and [CKL17] and the self-dual twist of the specialisation to the anticyclotomic line of the three-variable p-adic L-function of Skinner–Urban [SU14]
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

A study of an arc sensor model for gas metal arc welding with rotating arc - Part 2: simulation of an arc sensor in mechanically rotating gas metal arc welding
No full textThe high-speed rotating arc process forms a flat bead surface and decreased penetration depth. It can be effectively applied to automatic seam tracking, because the sensitivity of this type of arc sensor is greater than that of the conventional torch weaving method. In this study, a new rotation mechanism was developed by using a hollow shaft motor designed to be installed in the electrode nozzle. By rotating the welding arc, the amplitude of the current waveform increases remarkably since self-regulation of the arc is not fully performed. This paper presents a mathematical model for the dynamic behaviour of the electrode melting rate and arc length to simulate the welding signals in rotating arc welding. A simplified weld pool shape is considered with the dynamic wire melting model, because the welding arc rotates above the preformed weld pool
