Alfv en spectra in a reversed-shear tokamak plasma with a population of energetic ions exhibit a quasiperiodic pattern of primarily upward frequency sweeping (Alfv en Cascade). Presented here is an explanation for such asymmetric sweeping behavior which involves nding a new energetic particle mode localized around the point of zero magnetic shear.

For the first time, high amplitude (Deltan/n approximately 40%), high Q (up to 100 000) Bernstein, Greene, and Kruskal modes have been controllably excited in a plasma. The modes are created by sweeping an excitation voltage downwards in frequency, thereby dragging a phase space "bucket" of low density into the bulk of the plasma velocity distribution. The modes have no linear limit and differ ...

This article examines the career and reform agenda of Christopher Merrett as a means of evaluating the changing conditions of medical knowledge production in late seventeenth-century London. This period was characterised by increasing competition between medical practitioners, resulting from the growing consumer demand for medical commodities and services, the reduced ability of elite physician...

This article explores the intricate interrelationships between discourses on identity and themultiple processes associated with increasing globalization in the modern age. Globalization is notonly often exclusively associated with worldwide economic integration and the emergence of aborderless global market but also involves sweeping changes on the social, cultural and politicaldomains.
