In this talk I report on a thorough comparison between the bound state and rigid rotator approaches to generate baryon states with non–zero strangeness in chiral soliton models. This comparison shows that the scattering amplitude in the bound state approach contains contributions generated by the exchange of the rigid pentaquark excitation, and that the two approaches are consistent with each o...

This tutorial paper gives a fairly gentle introduction to the basic mathematics required to understand encryption systems. Three main areas are covered: modular arithmetic, prime numbers and probability theory. These should help the reader to understand how conventional and public-key encryption systems work, how they might be attacked and how to improve their security. snellwilcox.com Putting ...

To the Editor, I am writing this letter concerning the “Clinical Picture in Hematology” entitled “Isolated Zinc Deficiency Causing Severe Microcytosis and Sideroblastic Anemia” by Shweta et al. in a recent issue of this journal [1]. Although we have seen several cases of zinc and iron deficiency with geophagia, hepatosplenomegaly, growth retardation, and hypogonadism (Tayanç-Reimann-Prasad synd...

The old picture environment, introduced by Leslie Lamport into the LATEX kernel almost 20 years ago, appears to be neglected in favor of more modern and powerful LATEX packages that eliminate all drawbacks of the original environment. Nevertheless it is still being used behind the scenes by a number of other packages. Lamport announced an extension in 1994 that should have removed all the limit...

Figures 2 and 3 are time-lapse frames taken of the Sacramento WSR-57 radar repeater scope during the early morning hours of 'Dec. 20, 1968. A Fairchild recording camera was used. The aperture setting was f/8, and the film was 35-mm Eastman Plus-X, type 4231. Almost all echoes in the photographs are ground clutter. Figure 2 (1136 GMT) shows a weak apparent hook-or 6-shaped precipitation echo (A)...

The concept of tree-based picture generation is introduced. It is shown that there are equivalent tree-based deenitions of four picture-generating devices known from the literature, namely collage grammars, mutually recursive function systems, context-free chain-code grammars, and 0L-systems with turtle interpretation. Furthermore, generalisations of each of these systems are discussed.
