Book Description
Anna Seghers’s Transit is an existential, political, literary thriller that explores the agonies of boredom, the vitality of storytelling, and the plight of the exile with extraordinary compassion and insight. Having escaped from a Nazi concentration camp in Germany in 1937, and later a camp in Rouen, the nameless twenty-seven-year-old German narrator of Seghers’s multilayered masterpiece ends up in the dusty seaport of Marseille. Along the way he is asked to deliver a letter to a man named Weidel in Paris and discovers Weidel has committed suicide, leaving behind a suitcase containing letters and the manuscript of a novel. As he makes his way to Marseille to find Weidel’s widow, the narrator assumes the identity of a refugee named Seidler, though the authorities think he is really Weidel. There in the giant waiting room of Marseille, the narrator converses with the refugees, listening to their stories over pizza and wine, while also gradually piecing together the story of Weidel, whose manuscript has shattered the narrator’s “deathly boredom,” bringing him to a deeper awareness of the transitory world the refugees inhabit as they wait and wait for that most precious of possessions: transit papers.

IAU C196 coincided with the 8 June 2004 transit of Venus, producing the exciting, eclectic mix that can be found in these proceedings: the amazing history of the English North-country astronomers of the seventeenth century; the AU at a precision of 1.4 m; the explanation for the infamous black drop effect; a possible Mayan observation of a transit of Venus in the thirteenth century; the vexed question of leap seconds and time scales; history, distances, parallaxes, the solar system at exquisite precision and future space missions that will revolutionise astronomy.

Book Description
The Gunn-Hilsum Effect covers the physical principles controlling the operation of transferred electron devices. These devices have been proven quite useful in the generation, amplification, and processing of microwave signals well into tens of gigahertz range. Organized into seven chapters, the book focuses on the analytical and numerical approaches of the two vital aspects of device behavior for a given bulk semiconductor: boundary conditions or contacts and the local circuit environment. The opening chapter of this book discusses the negative differential mobility (NDM) characteristics for a range of electric fields in the velocity-field relation of specific semiconductors and the response of such a sample to a charge fluctuation, leading to the growth of stationary and/or traveling high electric field domains. The next two chapters describe how the boundary conditions and the circuit control the manifestation of current instabilities in such systems and how this control can be understood in a simple manner. Chapters 4 and 5 discuss the numerical and experimental investigations of comparatively long bulk samples, with an emphasis on the essential NDM semiconductor n-GaAs. These chapters also examine the production of different current-voltage relationships and instabilities by cathode contacts and the control of the oscillatory characteristics of an electrically unstable sample by different circuit conditions. Chapter 6 presents both time-independent and time-dependent computations, with the latter focusing on the small-signal impedance and stability aspects. The last chapter of this book addresses the construction and evaluation of typical short devices, describes how their oscillatory characteristics compare with the long samples studied in the first six chapters, and discusses the use of short devices as amplifiers. This book is an ideal source for device engineers and designers wishing to apply transferred electron devices in creative ways.
