The Federal Express Help Desk Expert System is a joint effort between AT&T and Federal Express with resources and responsibilities being equally shared by the two companies.

The large concentrations of free carriers (electrons or holes) present in modulation doped quantum well (MDQW) samples have important effects on their optical properties.

The concept of the ferreed was presented in an earlier article in this journal.1 The purpose of this paper is to describe the evolution of this device during its further development.

The spectacular success of the electronic technology during the last decade, particularly in the field of computers and semiconductors, has provided a challenge to the communication industry.

The Ferret Document Browser is a vehicle for exploring the design and use of broadband document storage and retrieval systems.

A variety of chiral esters of a range of 4-n-alkanoyloxybiphenyl -4'-carboxylic acids were prepared in order to produce three closely related homologous series of liquid-crystalline materials, The

The optically active 4-hydroxy-(2' - methylbutyl)benzoate esters of the 4-n-alkoxycinnamic acids have been made and characterized.

In a recent series of articles, Tellegen1 has discussed the possible applications of a new circuit element which he calls a gyrator.

The advantages of Digital Loop Carrier Systems operating on wire pairs can be enhanced by the use of lightguides in place of wire pairs.

The need for passive nonreciprocal structures has long been recognized.1 In the microwave field, Hogan's gyrator 2 paved the way for an increasingly important class of such devices.
