Dynamics of DNA Bubble in Viscous Medium
The damping effect to the DNA bubble is investigated within the
Peyrard-Bishop model. In the continuum limit, the dynamics of the bubble of DNA
is described by the damped nonlinear Schrodinger equation and studied by means
of variational method. It is shown that the propagation of solitary wave
pattern is not vanishing in a non-viscous system. Inversely, the solitary wave
vanishes soon as the viscous force is introduced.Comment: 4 pages. arXiv admin note: substantial text overlap with

Dynamical symmetry breaking of SU(6) GUT in 5-dimensional spacetime with orbifold S1/Z2
The symmetry breaking of 5-dimensional SU(6) GUT into 4-dimensional SU(3) x
SU(3) x U(1) with orbifold S1/Z2 through Scherk-Schwarz mechanism is
investigated. It is shown that the origin of Little Higgs can be generated to
further break SU(3) x SU(3) x U(1) down to the electroweak scale through Higgs
mechanism.Comment: 4 page
