The Zeeman-Hamilton operator of free charged particles are identified with the Laplacians of certain Riemannian manifolds, called Zeeman manifolds. The quantum Hilbert space, H, decomposes into subspaces (Zeeman zones) which are invariant under the action both of the Zeeman operator and the natural Heisenberg group representation. Thus a well defined particle theory and zonal geometry can be de...

Forty years have passed since the first Explorer orbiting observatory the 1958 mission used to discover the Van Allen radiation belts outside the atmosphere ushered in the modern age of space science. Even though in situ observations of outer space are still restricted to measurements made within the solar system, we now have access to a wide range of cosmic signals, extending from the well und...

To study the dynamical mechanism by which Arctic amplification affects extreme weather events in mid-latitude, we investigated local and remote circulation response to pan-Arctic regional thermal forcing. A comprehensive atmospheric GCM (General Circulation Model) coupled a slab mixed-layer ocean model is used for experiment. With increasing forcing configuration, mid-latitude jet tends shift e...

Regional metamorphism occurs in plate boundary zones. Accretionary orogenic systems form at subduction boundaries in the absence of continent collision, whereas collisional orogenic systems form where ocean basins close and subduction steps back and flips (arc collisions), simply steps back and continues with the same polarity (block and terrane collisions) or ultimately ceases (continental col...

This paper reports the diffuse X-ray features around the Galactic center observed with Chandra. We confirm the ASCA and Ginga discoveries of the large-scale thinthermal plasma with strong lines in the Galactic center region. In addition, many small clumps of emission lines from neutral (6.4 keV line) to He-like (6.7 keV line) irons are discovered. The 6.4 keV line clumps would be reflection neb...
