Integral curves, such as streamlines, streaklines, pathlines, and timelines, are an essential tool in the analysis of vector field structures, offering straightforward and intuitive interpretation of visualization results. While such curves have a long-standing tradition in vector field visualization, their application to Adaptive Mesh Refinement (AMR) simulation results poses unique problems. AMR is a highly effective discretization method for a variety of physical simulation problems and has recently been applied to the study of vector fields in flow and magnetohydrodynamic applications. The cell-centered nature of AMR data and discontinuities in the vector field representation arising from AMR level boundaries complicate the application of numerical integration methods to compute integral curves. In this paper, we propose a novel approach to alleviate these problems and show its application to streamline visualization in an AMR model of the magnetic field of the solar system as well as to a simulation of two incompressible viscous vortex rings merging.

Interview with postmaster and Army veteran J.D. Bradley. The interview includes Bradley's personal experiences about being a guard during the International Military Tribunal for the Far East in Tokyo after World War II, enlisting in the army, basic training, various assignments, guard duty in the court docks during the tribunal, and guarding Hideki Tojo. Bradley talks about rules and regulations for Military Police guards, steps taken to prevent suicides among the prisoners, the physical description of the interior of the courtroom of the War Ministry Building, checks for hidden weapons in the courtroom, courtroom procedures, various security procedures, steps taken to impress the Japanese people, living quarters and conditions at the War Ministry Building, relations with Japanese civilians, black market activities, his relationship with a Japanese correspondent and trading cigarettes for photographs of the proceedings, Sugamo Prison, and his commanding officer, Lt. Col. Aubrey S. Kenworthy. The interview includes an appendix with photographs.
