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.
We have experimentally investigated dynamical hysteresis behavior by changing the sweeping frequency of the cavity input field in the optical bistability of rubidium atoms (in a three-level atomic-type configuration) inside an optical cavity. The shape, width (or area), and direction of the hysteresis cycle are sensitive functions of the sweeping frequency for such an optical bistable system.
Monoclonal antibodies are widely used to target disease-related antigens. However, because conventional antibody binds to the antigen but cannot eliminate the antigen from plasma, and rather increases the plasma antigen concentration by reducing the clearance of the antigen, some clinically important antigens are still difficult to target with monoclonal antibodies because of the huge dosages r...
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...
