For this edition, a number of typographical errors and minor slip-ups have been corrected. In addition, following the persistent encouragement of Olga Oleinik, I have added a new chapter, Chapter 25, which I titled "Recent Results." This chapter is divided into four sections, and in these I have discussed what I consider to be some of the important developments which have come about since the writing of the first edition. Section I deals with reaction-diffusion equations, and in it are described both the work of C. Jones, on the stability of the travelling wave for the Fitz-Hugh-Nagumo...

The Great Lakes Computer Science Conference is held biannually in Kalamazoo, Michigan. It is a wide-focus conference concerning all areas of Computer Science. Typically, research in data structures, algorithms (both parallel and sequential), database and VLSI design. Artificial intelligence has received the most attention. The 1989 proceedings of the Great Lakes Computer Science Conference consists of 64 papers. Artificial Intelligence, with 11 papers, is the field which was widely attended.

Endovascular Interventional Neuroradiology is comprised of selected papers from the prestigious "Stonwin Medical" "Conference," which each summer invites a group of internationally prominent neuroscientists, bioengineers, neurosurgeons, and radiologists to explore and discuss selected topics of neurosurgical investigation. This volume addresses recent advances in endovascular approaches to cerebral circulation, including: Surgical exposure of the superior ophthalmic vein in the management of carotid cavernous fistulas at Johns Hopkins; Current and future perspectives in interventional...

Selected papers from the prestigious Stonwin Medical Conference, which each summer invites a small group of neurosurgical investigation. This volume presents recent advances in research and practice of surgery of the severed spinal cord. Future volumes will treat similarly focused, cutting-edge topics. In terms of editorial strategy, this series will afford Springer entree to a select groups of neurosurgeons.

The problems of surgical intervention in and about the diencephalic region have stimu- lated the interest of neurosurgeons throughout the world. It was therefore not totally surprising when Professor A. N. Konovalov proposed this topic for discussion at the Fifth Annual Stonwin Medical Conference. Bringing the leading figures in this area to New York for a roundtable conference was an exciting challenge. Professor Russel H. Patterson, Jr., generously consented to be our guest of honor. The conference was held at the Winston Estate on July 13-14, 1987, and met our every expectation for a...
