This volume describes the Pomeron, an object of crucial importance in very high energy particle physics. Starting with a general description of the Pomeron within the framework of Regge theory, the emergence of the Pomeron within scalar field theory is discussed, providing a natural foundation on which to develop the more realistic case of QCD. The reggeization of the gluon is demonstrated and used to build the Pomeron of perturbative QCD. The dynamical nature of the Pomeron and its role in small-x deep inelastic scattering and in diffractive scattering is also examined in detail. The volume concludes with a study of the colour dipole approach to high energy scattering and the explicit role of unitarity corrections. This book will be of interest to theoretical and experimental particle physicists, and applied mathematicians. First published in 1997, this title has been reissued as an Open Access publication on Cambridge Core.

Let us not go over the old ground, let us rather prepare for what is to come. -Marcus Tullius Cicero Improvements in the health status of communities depend on effective public health and healthcare infrastructures. These infrastructures are increasingly electronic and tied to the Internet. Incorporating emerging technologies into the service of the community has become a required task for every public health leader. The revolution in information technology challenges every sector of the health enterprise. Individuals, care providers, and public health agencies can all benefit as we reshape public health through the adoption of new infor- tion systems, use of electronic methods for disease surveillance, and refor- tion of outmoded processes. However, realizing the benefits will be neither easy nor inexpensive. Technological innovation brings the promise of new ways of improving health. Individuals have become more involved in knowing about, and managing and improving, their own health through Internet access. Similarly, healthcare p- viders are transforming the ways in which they assess, treat, and document - tient care through their use of new technologies. For example, point-of-care and palm-type devices will soon be capable of uniquely identifying patients, s- porting patient care, and documenting treatment simply and efficiently.
