Coefficient fields and scalar extension in positive characteristic
M. Fernandez-Lebron, L. Narvaez-Macarro
Let k be a perfect field of positive characteristic, k(t)_{per} the perfect closure of k(t) and A=k[[X_1,...,X_n]]. We show that for any maximal ideal N of A'=k(t)_{per}\otimes_k A…
Brownian Motion in a Granular Fluid
J. W. Dufty, J. J. Brey
The Fokker-Planck equation for a heavy particle in a granular fluid is derived from the Liouville equation. The host fluid is assumed to be in its homogeneous cooling state and all…
Bubble generation in a twisted and bent DNA-like model
Peter V. Larsen, Peter L. Christiansen, Ole Bang +2
The DNA molecule is modeled by a parabola embedded chain with long-range interactions between twisted base pair dipoles. A mechanism for bubble generation is presented and investig…
Effect of the Introduction of Impurities on the Stability Properties of Multibreathers at Low Coupling
J. Cuevas, J. F. R. Archilla, F. R. Romero
sing a theorem dubbed the {\em Multibreather Stabiliy Theorem} [Physica D 180 (2003) 235-255] we have obtained the stability properties of multibreathers in systems of coupled osci…
Modeling the thermal evolution of enzyme-created bubbles in DNA
D. Hennig, J. F. R. Archilla, J. M. Romero
The formation of bubbles in nucleic acids (NAs) are fundamental in many biological processes such as DNA replication, recombination, telomeres formation, nucleotide excision repair…
Moving breathers in bent DNA with realistic parameters
J. Cuevas, E. B. Starikov, J. F. R. Archilla +1
Recent papers have considered moving breathers (MBs) in DNA models including long range interaction due to the dipole moments of the hydrogen bonds. We have recalculated the value…
