Future evolution of cosmic structure in an accelerating universe
(Univ Chicago Press, 2003-10-20)
Current cosmological data indicate that our universe contains a substantial component of dark vacuum energy that is driving the cosmos to accelerate. We examine the immediate and longer term consequences of this dark energy ...
Mode Competition in Relativistic Magnetrons and Injection Locking in KW Magnetrons
(The American Institute of Physics, 2003-12-01)
Both relativistic and nonrelativistic magnetrons are under experimental and theoretical investigation at U of M. Relativistic (Titan‐6‐vane) magnetron experiments (300–400 kV, 1–10 kA, 0.5 microsecond) investigate mode ...
Deposition and Properties of Superconducting MgB 2 Thin Films
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-10)
The recently discovered superconductor MgB 2 with T c at 39 K has great potential in superconducting electronics. In this paper, we review the deposition techniques used for MgB 2 thin films in the light of a thermodynamic ...
GRB Afterglows and Other Transients in the SDSS
(The American Institute of Physics, 2003-04-14)
The Sloan Digital Sky Survey (SDSS) will image one quarter of the sky centered on the northern galactic cap and produce a 3‐D map of galaxies and quasars found in the sample. An additional 225 deg2 southern survey will be ...
Interstellar Pathfinder — A Mission to the Inner Edge of the Interstellar Medium
(The American Institute of Physics, 2003-09-02)
Interstellar Pathfinder (ISP), our first step into the interstellar medium, is a scientific investigation to study the outer boundary of our heliosphere and the interstellar matter that flows into it. A wind of interstellar ...
Ricci-Flat Metrics, Harmonic Forms and Brane Resolutions
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2003-01)
We discuss the geometry and topology of the complete, non-compact, Ricci-flat Stenzel metric, on the tangent bundle of S n+1 . We obtain explicit results for all the metrics, and show how they can be obtained from first-order ...
Surface reconstructions of In-enriched InGaAs alloys
(The American Institute of Physics, 2003-08-18)
The atomic structure of In0.81Ga0.19As/InPIn0.81Ga0.19As/InP alloy layers was examined using in situ scanning tunneling microscopy. The (2×3) reconstruction observed during growth by reflection high-energy electron diffraction ...
