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

Proton decay in 5D SU(6) GUT with orbifold S^1/Z_2 breaking in Scherk-Schwarz mechanism
Proton decay within 5-dimensional SU(6) GUT with orbifold S^1/Z_2 breaking is
investigated using Scherk-Schwarz mechanism. It is shown that in the model
neither leptoquark like heavy gauge bosons nor violation of baryon number
conservation are allowed due to the orbifold breaking parity splitting. These
results prevent too short proton lifetime within the model.Comment: 6 pages, Proceeding of the Conference in Honour of Murray Gell-Mann's
