A previous study of the Regge-eikonal model in $" is extended to QED. First we define a reggeon amplitude that is built up by tower diagrams, and then study multiregge exchange by use of Gribov's reggeon calculus. The situation is essentially the same as in @: The eikonal approximation is the true high-energy and weak coupling limit (S -co, N In s = fixed), but it breaks down outside of the weak-coupling limit. This confirms that the eikonal approximation as a model for Regge-cuts is not justifiable by field-theoretic arguments because of the neglect of inelastic intermediate states.

The Regge-eikonal model in $" field theory is studied within the framework of Gribov's reggeon calculus. A condition is derived that indicates what sort of multireggeon exchange diagrams are important for large energies, and it is shown that the eikonal form is valid only in the weak-coupling limit,
## Abstract In this article the forces associated with the gradients of a radio frequency (RF) field at the boundary between fluids and cell membranes are calculated, and it is shown that they can be large enough to affect the particle motion by amounts that are on the same order of magnitude as th
