This paper reviews ideas presented at the February 1997 Hedberg Research Symposium on petroleum exploration and production in fold and thrust belts, held in Veracruz, Mexico. Exploration in fold-thrust belts has been expanding rapidly due to recent discoveries, improved demand for gas, and improved access to promising areas. At the same time, the methods for exploring in fold-thrust belts and in developing fields have evolved significantly. This was the first AAPG conference to focus on exploration and production within this structural domain. This conference brought together geologists and geophysicists from around the world who are actively working in fold-thrust belts to share their experiences and to address a broad range of exploration and production concerns. Symposium topics included hydrocarbon generation, migration, entrapment and preservation, exploration methods and strategies, field development, and data acquisition. Numerous case studies were presented illustrating these topics. Although exploration and production in fold-thrust belts must address many of the same issues as in other structural plays, there are additional challenges. Fold and thrust belts, for example, are characterized by complex trap geometry;a complex burial and thermal history;a narrow time line between the onset of petroleum generation, migration, and trap development;and a complex history of fill and spill. Other challenges can include difficult terrain, poor seismic quality, high cost of field operations, environmental constraints, and drilling problems related to active tectonic stress regimes. Success in this setting requires efficient application of all available tools to mitigate risk and costs, but given the complex geology and relatively poor imageability, explorationists must be willing to persist in the face of initial failures. The conference offered many illustrations of successful exploration and development programs to encourage geologists and geophysicists working in

In the years before 1947, many if not most, engineers had the idea that it was physically impossible for a solid to amplify electrical signals. After Bell Labs demonstrated that this idea was wrong, how would engineers and managers go about bringing the new amplifying device up to the level of usability of the vacuum tube? How would its unique characteristics be exploited? How would we convince the armed forces that this device could meet their demanding applications? Why did the early transistors lend themselves well to computing circuits and lend themselves poorly to linear amplification? What was the origin of practices such as temperature cycling and burn-in that became widespread in later years? How did Astounding Science Fiction Magazine play a role? How was information exchanged with universities and government organizations:, How were project managers chosen and how did they manage? Some of the answers will be found in these memoirs recalling J.A. Morton's Signal Corps project and J.H Felker's TRADIC Phase I computer project.

The idea of moving picture expert group (MPEG) bitstream scaling relates to altering or scaling the amount of data in a previously compressed MPEG bitstream, The new scaled bitstream conforms to constraints that are not known nor considered when the original preceded bitstream was constructed, Numerous applications for video transmission and storage are being developed based on the MPEG video coding standard, Applications such as video on demand, trick-play track on digital video tape recorders (VTR's) and extended-play recording on VTR's motivate the idea of bitstream scaling, In this paper, we present several bitstream scaling methods for the purpose of reducing the rate of constant bit rate (CBR) encoded bitstreams. The different methods have varying hardware implementation complexity and associated trade-offs in resulting image quality. Simulation results on MPEG test sequences demonstrate the typical performance trade-offs of the methods.

The goal of this article is to show, from the discourses of drinkers' spouses, members of a ''cured-drinkers'' movement in France very different from the AA, what the idea of the contagious character of alcoholism means in the subjects' representations and by extension, what the idea of contagion may contain when seen from an anthropological perspective. This work rests on the observation that many people consider that their spouse's alcoholism makes them sick, and tend to identify with the sick person by finding effects of alcoholism on their own bodies. The notion of contagion qualifies here the perception of the impact of the other's sickness on oneself, by physical and social proximity to the drinker, insofar as the conditions for contagion to be possible include not only sharing the same physical (domestic) space, but also the existence of a social bond.

Based on the common eigenvector of two particles' relative position and total momentum and the idea of Lq representation for describing a particle in periodic lattice we construct a new representation in two-mode Fock space. Squeezing operator in this representation is studied.

This broad-brushed look gives an idea of recent developments in Japan's parallel processing technologies. Workstation clusters, vector parallel processing, the dataflow model, and certain core technologies stand out. National projects transfer technology to business well, but their focus on specific applications has mixed results.
