We have implemented a 2D electrostastic plasma particle in cell (PIC) simulation code on the Caltech/JPL Mark IIIfp Hypercube. The code simulates plasma effects by evolving in time the trajectories of thousands to millions of charged particles subject to their self-consistent fields. Each particle`s position and velocity is advanced in time using a leap frog method for integrating Newton`s equations of motion in electric and magnetic fields. The electric field due to these moving charged particles is calculated on a spatial grid at each time by solving Poisson`s equation in Fourier space. These two tasks represent the largest part of the computation. To obtain efficient operation on a distributed memory parallel computer, we are using the General Concurrent PIC (GCPIC) algorithm previously developed for a 1D parallel PIC code.

Dynamic load balancing has been implemented in a concurrent one-dimensional electromagnetic plasma particle-in-cell (PIC) simulation code using a method which adds very little overhead to the parallel code. In PIC codes, the orbits of many interacting plasma electrons and ions are followed as an initial value problem as the particles move in electromagnetic fields calculated self-consistently from the particle motions. The code was implemented using the GCPIC algorithm in which the particles are divided among processors by partitioning the spatial domain of the simulation. The problem is load-balanced by partitioning the spatial domain so that each partition has approximately the same number of particles. During the simulation, the partitions are dynamically recreated as the spatial distribution of the particles changes in order to maintain processor load balance.

Two articles, one written by Elaine Schad titled 'The Art of Teaching Art' and another by Susan Shelton titled 'Denton school participates in art program', for the Denton Record-Chronicle. Both pieces cover art education in local schools and the help of NTIEVA and their teaching of DBAE.

Article discusses the flight schools in Oklahoma that left an impact on U.S. Army Air Force history by training pilots for participation in World War II. Leo Kelley includes recollections from the pilots who trained in these schools to create a portrait of the experience.

Article describes the period of historic preservation in the 1980s in Guthrie, Oklahoma to restore the downtown area. Charles L. W. Leider discusses resource surveys of the area and recommendations for preservation of the Victorian-style architecture.

For the Record section including the minutes of the quarterly board meeting of the Board of Directors of the Oklahoma Historical Society that was held on July 25, 1990.

Editorial contrasting the private, personal near-death experience with the public concept of the experience, and finding important messages for humanity that are common to both.

Article discusses the use of cane and reed whistles among the tribes of Eastern Oklahoma, examining the physical details of the artifacts and providing some historical context.

Article creates a biographical portrait of the life and career of James C. Neal, the first director of Oklahoma A. & M.'s Agricultural Experiment Station, and the lives of his family. Berlin B. Chapman examines key correspondence from the Neal family to construct a clearer picture of the times and their connection to the founding of Oklahoma A. & M.

Article proposing three etiologies responsible for the near-death experience, which are referred to as an altered state of consciousness: physiologic, pharmacologic, and psychologic. It recommends research to determine what developmental factors influence the emotionality of the experience and how in-depth understanding can be used to provide better patient care.

Notes and Documents column including a description of the Paul Miller Papers and their contents. Kayla Barrett provides some biographical information about Paul Miller, who donated the materials to Oklahoma State University in 1982.

Article examines the cultural heritage and legacy of John Rollin Ridge, a journalist of Cherokee descent who went into hiding after killing a man. Clyde Ellis explores his relationship with Cherokee leader Stand Watie and his identity as an expatriate of his tribe.

The Dallas Voice featuring an article about LGBT friendly candidates and a campaign ad for Ann Richards.

An article from the High Points Pilot Point ISD newsletter written by Jackie McBroom about the Gee Junior High School and new art program led by the NTIEVA group. At the bottom are pictures of the new teachers.

Article from the Slatonite newspaper about a bid to save the Slaton Harvey House from being demolished.

A group of documents from the U.S. Department of Health and Human Services announcing 60 new postdoctoral fellowships in AIDS research with the support of the National Institute of Allergy and Infectious Diseases.

Article describes the life and career of Charles H. Sawyer, an artist and attorney from Connecticut who moved to Indian Territory to participate in the Dawes Commission. James C. Milligan and L. David Norris discuss his accomplishments, which included creating the state seal, and political cartoons.

For the Record section including the minutes of the annual meeting of the Oklahoma Historical Society and the minutes of the quarterly board meeting of the Board of Directors of the OHS that were both held on April 13, 1990.

Article purporting that near-death studies can be viewed within a theoretical framework of "paradigms" and "paradigm shifts" as explicated by Thomas Kuhn. Assuming the validity of Kuhn's model, it hypothesizes that the paradigm of today's "normal science" is shifting to a new paradigm to accommodate data from near-death studies.

Article explores the public perception of Oklahoma throughout history by examining its representation in various forms of media such as film, magazines, newspapers, and novels. Tommy R. Thompson discusses the changes in Oklahoma's public image as it went through periods of recession as well as periods of economic progress.

Study of near-death verdicality in the hospital setting. The paper describes problems, both anticipated and unanticipated, that were encountered. Based on the successes and failures of this undertaking, recommendations for future research of this type are presented.

Article reviewing one previously reported and three new pediatric near-death experiences (NDEs), in which the experiencers were interviewed as children, and which suggests that the childhood core NDE as described by Melvin Morse and colleagues may be expanded to include feeling pain-free, seeing a light at the tunnel's end, entering the light, and time alteration.

Article describes the establishment of the University of Oklahoma Press, their unionization efforts, and bargaining with university administrators for benefits. Cynthia J. Wolff provides historical context for the attitudes towards unions during the mid-twentieth century.

Article explores the skirmishes led by Texas cavalry units and their Indian allies in the south that acted as a precursor for a much larger conflict, the Civil War. Douglas Hale investigates how loyalties to the different armies caused intertribal conflict and damage to Indian Territory.
