We identify primal and dual formulations in the finite element method (FEM) solution of the vector wave equation using a geometric discretization based on differential forms. These two formulationsâ€¦ (More)

Using Eulerâ€™s formula for a network of polygons for 2D case (or polyhedra for 3D case), we show that the num dynamic degrees of freedom of the electric field equals the number of dynamic degrees ofâ€¦ (More)

When Î¼eÎ³ (or Ï„Î¼Î³) loop involves a vector boson, the amplitude is suppressed by more than two powers of heavy particle masses. However we show that the scalar boson loop diagrams are much less damped.â€¦ (More)

By studying the nonperturbative contribution to the Dokshitzer-Gribov-LipatovAltarelli-Parisi and Gribov-Levin-Ryskin equation, it is found that (i) the nonperturbative contribution suppresses theâ€¦ (More)

It may be true that mankind's hope is the identification of the living meaning of natural structures. However, scientists including physicists, chemists, and biologists have not found any evidence ofâ€¦ (More)
